As no one, I believe, will attempt to dispute my claim to being the father of canine pathology, it will be expected of me, as its parent, from time to time to be doing something for the child of my adoption. Not to disappoint such expecta- tions, this edition will be found to present some important alterations, improvements, and additions. The anecdotical . portion, as not necessarily connected with the subject at large, has given place to a more strict philosophical inquiry into the animal himself, and to the introduction of many diseases not noticed before. The matter of the work is now divided into three parts. The first embraces the Natural History of the Dog, with an Inquiry into his individual ori- gin, and into the source of some of his prominent varieties. The second part is devoted to a theoretical and practical consideration of the System of Breeding and Rearing these Animals, with their general Treatment, as conservative of Health. The third part comprehends the Diseases of Dogs; the alphabetical arrangement of which, in former editions, has given place in this to such a methodical classification as, while it renders it not less easy of reference to the amateur, will be more acceptable to the professional reader, from the relative view it will afford him of the various subjects thus congenerously grouped. Not that what is now offered has any pretensions to a strict nosological classification : on the contra ly, it is evident that the work must yet be so framed A 4 PREFACE TO THE THIRD EDITION. as to be a vade mecum to as many non-medical as medical readers; and a rigorous application of nosology would, therefore, be too technical for the occasion. It may here- after assume a still more systematic dress: at present, festi- natio tarda est will probably apply; and until circum- stances allow or call for it, attempting too much might be found to be a preventive to the attaining of a little even. As regards the work generally, if my exertions should tend to alleviate the sufferings of an animal whose utility and good qualities can never be too highly estimated, I shall have accomplished my object : and here, probably, my ad- dress ought to terminate ; but during the course of a long life, the circumstances of having been seen so repeatedly changing from one to the other of the seeming discordant pursuits" of human and brute surgery ; of army life, both military and medical ; and of private life, as the country sportsmen, or the closeted author; have, I am aware, ex- cited the curiosity of many, and subjected me to the tax of great inconsistency of conduct, and vacillation of purpose from others. Wishing, in common with the rest of man- kind, to stand well with the world, and knowing that, however I may not be able entirely to rid myself from these imputations, I may yet, by detailing the principal circum- stances which led to these constantly varying pursuits, shew that they were less sought by than forced on me, and that by such apologetical statement I may at once blunt censure and satisfy curiosity ; with which intentions only I am induced further to intrude by the following PROFESSIONAL LIFE OF THE AUTHOR. I was educated with my maternal grandfather, a dignitary of the cathedral of St. David's; the bishop of the diocess becoming my godfather, with an understanding that I was to be brought up to the church, under his auspices. Unfortunately, the prin- ciples of my father, as a dissenting divine, frustrated these pros- pects ; and it was at length agreed between the two parents, that I should be consigned to a less scholastic but more la- borious profession, the ars medendi, which first aberration laid the foundation of all the subsequent ones ; for of all professions, that of a parish priest oifers the fewest temptations to deviate from a direct course. In consequence of this agreement, I was, at the age of fourteen, placed with an eminent practitioner in Buckinghamshire ; and at twenty-one was entered a pupil at the Borough Hospitals, under the direct guidance of the ingenious Dr. Haighton, where I remained nearly three years, the last of which was passed under the roof of this friend of my family; and to whom, during my stay, it was my study to discharge some of my obligations, by actively employing myself in assist- ing him in his physiological experiments, and in myself making many of those particular dissections, and the whole of the draw- ings designed to illustrate the re-union of divided nerves, and the nature of the interposed substance, that gained him the prize medal of the Royal Institution ; and which further led to the discovery of the division of the facial nerves as a cure for tic douloureux. About this time the public attention became en- gaged in forming a national college for the systematic study of brute medicine. One professor (M. St. Bel) had been already engaged; and there was yet wanting an assistant teacher of a 2 6 PROFESSIONAL LIFE OF THE AUTHOR. anatomy and demonstrator; which being offered me, I accepted, and by so doing a second important aberration from purposed intentions was committed ; but enthusiastically attached to ani- mals as I was, as well as to natural history and comparative anatomy, it was little to be wondered at, if a young man should embrace a situation where his duties and his inclinations so well accorded. It may also readily be supposed, that the time thus passed would tend to divert my attention from my legitimate profession of human medicine; and although, after I left the Veterinary College, I resumed it for a twelvemonth in Sussex, yet I was again influenced, by strong temptations held out, to enter on a course of public teaching of the veterinary art; and also to engage in the practice of it at Lewes, where I met with much notice and encouragement. An improvident management of my resources, however, forced me from hence ; and I once more resumed human surgery in a regiment of mihtia, with which I remained, until, at the recommendation of the late General Gwynne, always a kind and zealous friend, I was appointed to a surgeoncy in one of the troops of horse artillery, then stationed at Woolwich, with which I remained nearly three years, extend- ing my knowledge of human medicine by witnessing the judicious management of the Woolwich Artillery Hospital, under the direction of the late Dr. Rollo ; and as though tlie practice of brute medicine was ever to mute itself with whatever other pur- suits I might be engaged in, I was requested to add to my duties the inspection of the extraordinary cases which might occur among the invalid horses belonging to the establishment. As may be supposed, my time spent here was neither idly, unpleasantly, or nnprofitably employed; but my relations be- coming urgent with me to leave the army, and wholly con- fine myself to human medical practice near them, I left the Artillery, and made my debut as a surgeon in the neigh- bourhood of Queen Square, London. Even here, however, the latent spark, which had smouldered but was not extinguished, again shewed itself by the employment of the hours that my PROFESSIONAL LIFE OF THE AUTHOR. 7 professional avocations left me in preparing and publishing the Anatomy of the Horse, in folio monthly numbers, with botli coloured and plain plates. Of this work, it is certainly not too much to say, that it was a spirited undertaking : it was also thought so worthy of encouragement by that excellent character and great lover of this animal, George the Third, that he was pleased personally to urge my continuance of it, giving me, at the same time, permission to dedicate it to him. Settled as [ now appeared to be, even yet a new aberration awaited me, fate herself seeming to have ordained that I should not remain long in one situation ; for the death of a near relative investing me with a considerable property, I relinquished my professional pursuits, and retired into the country, where the expences of a sporting establishment in a few years forced on me the necessity of again adopting a new course of life. In consequence, I first accepted a commission in the North Gloucester Regiment of Militia, and in it, passed a campaign in Ireland during the rebellion; but after two years wasted in this manner, prudence dictating that it was doing nothing towards my future welfare, on the announce- ment of the expedition to the Helder, I offered my services to the Medical Board, which were accepted, and 1 was provision- ally appointed surgeon to the second battalion of the 40th re- giment, with which 1 immediately embarked for Holland. As this corps particularly distinguished itself, and bore the brunt of several actions, my experience in my profession received consi- derable additions ; but neither my prospects nor interests seemed to be much brightened by my services, although a public ac- knowledgment of them by the regiment, coupled with a request for my continuance with it, was formally made to the Medical Board ; but which availed little, for the system of favoritism of the surgeon-general of that time made him, at the instance of Ge- neral Cameron, then embarking for the West Indies, order me to accompany him, although but three weeks returned from Holland. Indignant at such treatment, 1 refused to go ; and thus any claim of mine for active service in several regiments was, in one mo- 8 PROFESSIONAL LIFE OF THE AUTHOR. inent, cancelled. Some years after this, when in professional attendance on the late excellent Duchess of York, her princely consort admitted my active services on the Continent (for he had often himself inspected my hospital regulations, with which he always expressed himself as particularly well pleased), and tliat they deserved a different treatment from the Medical Board, hut over which he had no controul. After this throwing up of my commission, I did not immediately turn my attention to any new pursuit, but remained some time in suspense, at the instance of my kind friend and patron Lord Craven, who also had' himself left the 40 th regiment, with some expectation of obtaining the command of a rifle corps, and in which he promised to procure me a commission, in case his interest should fail to gain me the surgeoncy of it. I was, however, to be again foiled, together with his lordship, who, instead of his meditated appointment, was promoted to the rank of a district general ; and I was conse- quently once more left to pursue my own fortune. Being not altogether destitute, I was in no hurry at that moment to risk a new run of ill luck ; but, on the contrary, quietly retired into the north of England, where my days were occupied in sketching, shooting, or fishing, and my evenings in arranging my materials for the First Edition of the Veterinary Outlines. But such a plan of life did not long accord with my naturally active habits ; and, moreover, it offered no prospect of future benefit and ad- vancement. I began therefore again seriously to consider, to what object I should next turn my attention. The practice of human medicine naturally presented itself ; but it was unpleasant to reflect, that 1 bad lost some years in my start, and that my cotemporaries, from the advantage of early residence and local- ity, had outstripped me in the race ; and that, the market being already overstocked with human surgeons, I had numerous diffi- culties to overcome, and additional time to waste, before I could hope to get even into tolerable practice. I, however, removed to London, where I some time lingered in uncertainty : but my Veteri- nary Outlines, which I had in the mean time published, becoming PROFESSIONAL LIFE OF THE AUTHOR. 9 known, together with the public remembrance of what little no- toriety attached to my name as an early teacher at the Veterinary College, almost insensibly, and certainly unexpectedly, drew me into correspondences and practice on the diseases of horses, dogs, and domestic animals in general, which, increasing daily, at length determined me to devote all my future professional energies to these subjects. In this almost unbeaten tract I might hope to reap both fame and emolument ; and although it might not appear so honourable a calling as that of human medicine, it was, at least, a very useful one, and, under all the foregoing cir- cumstances, the most prudent one. The resolve was followed by a popular and extensive practice in the British metropolis, during which I produced a successiou of veterinary publications, all of which have received the meed of public approbation, by passing through several editions, and by having been translated into several continental languages. Firmly resolved no more to deviate from this settled line of practice (which, although it was not that it has ever been my wish that I had remained in, yet has proved a remunerating one to me, and 1 hope not altogether a useless one to the public), I remained engaged in it for twenty years, although twice exposed, during that time, to temptations of a profitable and flattering nature to translate my professional services, first to India, and next to Russia. To induce me to take the direction of a veterinary school in Peters- burgh, Prince Gargarini was directed, when the crowned heads were in England, to offer me the usual temptation of a title, with a liberal pension. By declining these, I hope I somewhat reclaimed a character for consistency, if not for prudence and wish for aggrandizement. For myself I have never repented the step ; the retirement I have some years enjoyed, is still em- ployed in editing new editions of my former works, or collecting materials for others connected with the improvement of the per- sons and treatment of our domestic animals. Thus, though hap- pily not called on by want, my energies, my competence, and 10 PROFESSIONAL LIFE OF THE AUTHOR. my leisure, are yet devoted to the cause of humanity, aud to that course which chance forced me into. Little as this recital offers for boast or exultation, I shall, without doubt, be taxed with egotism and vanity, by introducing it. I have unquestionably personal motives in so doing ; but if I know myself, they centre in the hope that thereby I may at once satisfy all curiosity ; and that wherever I may be, I may stand confessed to the world with regard to what I have been, and with regard to what I am, and ever mean to be. We have every one of us a sphere of action of our own : mine is a humble and limited one ; but the more narrow its limits, the more ne- cessary is it that it should not be clouded by any doubts or obscurities. PART THE FIRST. THE NATURAL HISTORY OF THE DOG, AND HIS VARIETIES. THE importance of the dog in the scale of animated nature admits of no dispute ; but, on the contrary, is forced on our conviction by many striking proofs ; among which the wide range of his geographical distribution, which exceeds that of almost any other scion of the zoological tree, stands prominent1. Its weight, indeed, is such as nearly to persuade us that no country is largely blessed with Nature's gifts which does not possess the dog ; and certainly none can deserve the title of civilized, which, owning him, has not engaged him in a close domestication : on the contrary, we have reason to believe that it was one of the earliest efforts of associated man, to secure to himself and fellow men the friendship and services of an animal whose manners, in his wild state even, must have exhibited physical and intellectual powers which, in an eminent degree, qualified him, when reclaimed, to become a watchful and effective guard against the more predatory and ferocious brutes around ; a powerful assistant and ally in that further conquest which he (man) would be naturally led to medi- tate over other animal races ; as well as a devoted and interesting 1 " Almost every nation of the earth, intertropical, temperate, and polar, possesses its own peculiar variety of the dog ; the theatre of observation, there- fore, is the world itself; and any thing like a description of the whole race would require a much more intimate knowledge of the surface of the earth than is at present obtained."— Griffith's Animal Kingdom. 12 NATURAL HISTORY OF THE DOG. companion2. Indeed, his protection against tlie ferocity of other animals could hardly be obtained by any other than this canine compact : neither is it too much to assert, that but for this he could never have extended his conquest over other brute races, or, having effected it, it would have been utterly impossible to have maintained it. In great truth, therefore, the subjugation and domestication of the dog may be called the triumph of reason over nature ; and, as observed by Baron Cuvier, it is the most complete, singular, and useful conquest, man has ever made. Viewed in these several relations, our inquiries concerning the dog necessarily embrace, first, his natural history, properly so called ; and, secondly, his artificial history, or the alterations effected in him by his domestication with man. The natural history of an animal is most satisfactorily com- menced by inquiries into its direct origin ; and in this instance it would be peculiarly gratifying to trace the source from whence has been derived a race now so extensively diffused among us ; and one that is become not more important by the value of its services, than interesting by its amiable and com- panionably qualities. But, unfortunately, we have to lament, that around the descent of no quadruped does there hang so much obscurity as about that of the dog ; and however reason and analogy may lead us to conclude him an original animal ; and however well convinced the majority may be that he is so, yet the subject is so beset with difficulties and contradictory appearances, that we cannot wonder at the doubts which exist in the minds of others on the subject. Some eminent naturalists have even doubted, whether the dog be not wholly a factitious 2 " The intelligence and moral qualities of the dog, which it possesses in common with the rest of the class, though much greater in degree, form a sub- ject perfectly impenetrable by our limited faculties: we may contemplate the effect, but can by no means arrive at the cause ; we may speculate and conjec- ture, but can never demonstrate." Loc. cit.—u It is the dog only which takes delight in associating with us; and it is impossible for the naturalist, when tak- ing a survey of the whole animal creation, not to feel a conviction, that this friendship between two creatures so different from each other must be the re- sult of the laws of Nature." — Bltrchell's Travels in Africa. NATUHAL HISTORY OF THE DOtJ. 13 animal; one not acknowledged by tlie great architect of nature, but altogether compounded from such spurious sources as the intermixture of various nearly-allied animals. Others have al- lowed him a more direct lineage, by confining his descent to one among those which compose the genus in which he is placed : thus, some have considered his parentage derived from the wolf, some from the fox, others from the chacal or jackal, and a few have regarded the hyena as his primogenitor. So infinitely varied are the scions of this great tree, that among those who, like myself, strongly advocate his claim to originality of forma- tion, there are many of them who yet deem it impossible that all of his varieties can have sprung from one root. They can- not bring themselves to suppose, that even the powerful agencies of climate, food, and domestication could have operated diver- sities so monstrous and so multiplied ; but, on the contrary, they maintain that he was originally formed in such corresponding varieties as fitted him to inhabit the different countries in which he was placed. I am as much as ever inclined to the opinion that the dog, in his native character, is an original animal ; but whether he descended from an individual type, or from types fitted for different localities ; whether he may not by intermixture with other members of his genus have also diversified his kinds, I am not ready to assert, nor prepared to deny. But when wre regard attentively the effects produced by the powerful agencies already hinted at, particularly that resulting from climate, and that brought about by man when he assumes to himself the di- rection of the sexual intercourse, I cannot but incline to think, that the varieties of this animal, numerous and disproportionate as they are, might result from these united causes of themselves. I am convinced that this is at present the less popular opinion ; but as I will endeavour to examine it with candour, and will equally state the arguments against it, as those for it, I cannot mislead by such a course, even if my opinion could be supposed to weigh materially : on the contrary, I shall further the cause of truth by a discussion thus conducted ; and if a satisfactory 14 NATURAL HISTORY OF THE DOG. conclusion cannot be drawn by a few moments thus spent, at least it will not be uninteresting- to the admirer of the animal, who may, perhaps, more readily afterwards draw his own inferences therefrom. In the zoological arrangement of the great naturalist, Sir Charles Linne, the Dog, Cams familiaris, is the first species of a genus which comprehends animals whose exterior forms and habits are considerably varied, but whose generic characters bear a close resemblance to each other. The animals included are, the Wolf, Can. lupus; the Fox, Can. vulpes ; the Jackal, Can. aureus, and the Hyaena, Can. hya>na3. The characters of the genus are drawn from the number and the incisive formation of the teeth. There are, in front, six pointed conical fore teeth above and below ; the laterals being more lobated and longer than the others. The molar or grinding teeth are furnished with pointed prominences, and in the intermediate space between the incisor and molar teeth placed on each side, above and below, is found a solitary incurvate tush, from whence this tooth derives its characteristic name of canine, wherever it is met with. The specific characters, or those by which this great master distin- guished the dog from the other members of the genus, are — the head carinated or keel-shaped on the crown ; the lower lip hid by the upper, indentated and naked at the sides; tongue smooth ; five rows of whiskers on the upper lip ; nostrils turned outward, into a crescent-shaped furrow ; upper margin of the ears reflected and doubled posteriorly ; anterior margin three lobed, with seven or eight hairy warts on the face ; teats ten, six abdomimil, four pectoral ; feet subpalmated, toes furnished with curved claws, not retractile. Baron Cuvier excludes the hyaena from the genus Canis, but retains the other members of the Linnaean arrangement. His generic characters are - three false molars above, four below, 3 The hyena is not admitted among the canina; of modern naturalists. A more close anatomical comparison has shewn that his organization required the for- mation of a distinct niche for his reception, as will be further noticed. NATURAL HISTORY OF THE DOG. 15 and two tuberculous teeth behind each carnivorous one. The first of these tuberculous teeth in the upper row is very large. The upper carnivorous tooth has but a single small tubercle within, but the lower one has its posterior point altogether tuber- culous. Their tongue is soft. The fore feet have five toes, and the hinder four." "The specific characters of the domestic dog, Canis fami- liaris, L., are— his curved tail, and his variations, ad infinitum, as to size, form, colour, and the quality of the hair. The dog is the most complete, the most remarkable, and the most useful conquest ever made by man. Every species has become our property ; each individual is altogether devoted to his master, assumes his manners, knows and defends his property, and re- mains attached to him until death; and all this proceeds neither from want nor restraint, but solely from true gratitude and real friendship. The swiftness, the strength, and the scent of the dog, have created for man a powerful ally against other animals, and were, perhaps, necessary to the. establishment of society. He is the only animal which has followed man through every region of the earth. « Some naturalists think that the dog is a wolf, others a do- mesticated jackal. The dogs, however, which have become wild again in desert islands, do not resemble either of these species. The wild dogs, and those belonging to barbarous people, such as the inhabitants of New Holland, have straight ears, which would lead us to the belief that the European races, which ap- proximate the most to the original type, are our shepherd's dog and our wolf-dog. But the comparison of crania points to a closer approximation in the mastiff and Danish dog: after which come the hound, the pointer, and the terrier, which do not differ between themselves except in size and the proportions of the limbs. The greyhound is more lank, and its frontal sinuses are small, and its scent more feeble. The shepherd's dog and the wolf-dog resume the straight ears of the wild dogs, but with a greater development of the brain, which proceeds increasing, with a 16 NATURAL HISTORY OF THE DOG. proportionate degree of intelligence, in the barbel and the spaniel. The bull-dog, on the other hand, is remarkable for the shortness and vigour of its jaws. The small chamber dogs, the pugs, spaniels, shock dogs, &c, are the most degenerate productions, and constitute the most striking marks of that power which man exercises over nature. " The dog is born with the eyes closed. He opens them the tenth or twelfth day. His teeth begin to change in the fourth month, and his growth terminates at two years of age. The female goes with young sixty-three days, and brings forth from six to a dozen young ones. The dog is old at five years, and seldom lives more than twenty. The vigilance, the bark, the singular mode of copulation of this animal, and his striking susceptibility of a varied education, are universally known4." The artificial history of the dog may with propriety commence with the synopsis of the varieties into which he is branched out. In the other species of the genus to which he belongs, this would rather belong to their natural history ; but it must be considered, that by far the greater number of the varieties "of the dog have been the result of circumstances not contemplated by nature : on the contrary, many of them, we know, have arisen from the direct agency of man himself ; and the greater proportion are wholly domesticated with him. The synoptical view of this subject taken by that eminent zoologist M. Frederic Cuvier (a younger brother of the Baron), being now very generally fol- lowed by our best naturalists, will furnish me with an order of description slightly varying from that pursued in the last edition, but not, I believe, less demonstrative or interesting. Founded on the construction of the various organs of the body, internal as well as external, these illustrious brothers have reared their 4 This illustrious naturalist evinces some of the nationality which marked Buffon in his reveries on the origin of the dog: nor can I agree with him that the dog is old at five ; he is, on the contrary, then in his prime. And by limiting the number of progeny to twelve, he is equally in error: I took myseb from a pregnant setter, after her death, sixteen young ones, within a week of their expected birth. NATURAL HISTORY OF THE DOG. 17 systems on the most solid base ; employing principles wliich must produce the best effects on zoology, by rescuing it from fabled representation, traditionary account, or purposed exaggeration5. The shape of the head, and the length of the jaws and muzzle, have furnished him, as he conceives, with facilities in arranging the dog varieties in the order of their approach to the parent stock, which he does in three several groups. 1. Matins5 ; 2. Spaniels^ ; 3. Dogues. 5 It is true, that a general view of anatomical structure has been that wliich has been pursued in the various systematic arrangements, from Aristotle to Lin- naeus, who also framed his groupings on structural criteria. But as it was principally founded on the existing peculiarities of the organs of circulation in such animals as possessed a cardiac system, so it was too general, and by no means sufficiently precise for the critical distinctions required by genera even, and still less of species; as we have seen instanced in the introduction of the hyena among the canina?. Zootomy is of little use whenever it is confined to any single manifestation of life: structure and function are inseparable ; and as the functional manifestations are numerous, so must the structural display be extensive, or it will fall short of its ends. In the immense variety of ani- mated forms which surround us, we are dazzled by the complexity which ap- parently belongs to each, and are apt to shrink from the seeming arduous task of further inquiry. But if we regard nature on the principles of true philoso- phy, we shall find that a fundamental simplicity reigns throughout her works; and provided we commence by an examination and comparison of the organi- zation with each other; if we extend it to the development of organization and function, as viewed in those in the next degree of complexity; progressing to the highest link in the chain; the task will be rendered easy, and we shall be no less surprised with the simplicity and unity of nature's laws, as displayed by such an examination of the animal kingdom throughout, than by the progres- sively increasing perfection in structure of its members as we advance. It is the apparent uniformity and harmony observed throughout every page of Nature's history, particularly as regards animal life, which embarrassed the attempts of the early zoologists: the gradations of organization, when cur- sorily or exteriorly viewed only, slide into each other with such lightly touched shades, that it is not to be wondered at, if in the absence of the stronger mark- ings and distinctive lines traced by comparative anatomy, the divisions proved incorrect, or the groupings imperfect. 0 I do not think this a sufficiently precise term for this group, nor, indeed, a correct one, according to the usual translation of the term mastiff. With- out, however, here entering into the origin of this dog, the matins are none of them properly mastiffs. 7 Spaniels, as derived from dogs of Spain, is evidently erroneous, when it includes those of Newfoundland, Siberia, &c. If it bespeaks dogs with a particular cOTering, il includes every variety, from the wiry hair of the northern 18 NATURAL HISTORY OF THE DOG. 1. MATINS. " The anatomical character of this group is— the head more or less elongated ; the parietal bones insensibly approaching each other ; and the condyles of the lower jaw placed in a horizontal line with the molar or upper cheek teeth."

If it is to class together dogs of scent, it should have taken in all the former, but particularly the Irish greyhound, or boar-hound of by-gone times, a dog of exquisite scent. 8 M. F. Cuvier finds the head of this half-reclaimed animal to resemble that of the French matin, and his form to approximate to the shepherd's dog; and hence he places it at the head of the list, as retaining most of the distinctive characters of the wild and original stock. 9 A nationality not uncommon with the French has made their naturalists attach wonderful importance to their matin, as the progenitor of most of our large and valuable breeds. Pennant identifies it with the Irish greyhound, which it somewhat resembles; but it is not so tall, nor is its hair so wiry. It is very common in France as a cattle dog, and ageneral guard ; but in my own opi- nion it is, at least, not the genuine source from whence we derive our greyhounds. Still less is it connected in any way with either the bull-dog or the mastiff of England ; but much more with the boar and wolf-hound. Sir William Clayton observes, "The French matin is tall and slender for his size, and resembles a half-bred greyhound." Mr. Wilson also says, "It appeared to me a kind of lurcher; and if I were to analyse its characters, I would say it was an inter- mediate between the shepherd's dog and the greyhound." It may be added, that it is strong, courageous, and swift ; yet not deficient in the sense of smell, and was originally of a fawn colour, though I believe- it is now Often varied. Buffon's fanciful theories made this dog, which in its origin he considers a native of temperate climates, to become the Danish dog when carried to the north, and the greyhound when under the influence of the south. It is evident he could not become the English greyhound by this principle ; and, indeed, we have sufficient reason to believe we derive the greyhound from a very different source. It is to be regretted that Mr. Griffith did not lend his powerful aid to a more critical examination of the sources of these several varieties. Original and valuable as are some of his elucidations, he is lamentably meagre here, instead of a close investigation; he appears to conclude that the Moloss.an or Albanian do>r, the French matin, the Irish greyhound, with the Danish dog, and even the modern greyhound, are but ramifications of each other This » settling the matter concisely, but certainly not satisfactorily.

Misconceptions arise, by either confounding this dog with the Dalmatian, or otherwise from not considering the Dane in two distinct varieties : 1. The Great Dane, he Grand Danois, Buffon, which is considered as one of the largest dogs known. Marco Paolo must have inflated those probably which he describes as having seen of the size of asses. They are smooth coated, and appear to have been of a light fawn colour ; but are now often seen brindled, or broadly spotted, or patched with a dingy brown on the ori- ginal ground. The dogs of Epirus, so famed for their strength and courage, were of this kind. (Aristotle, lib. iii, c. 21. Pliny also notices them in terms of admiration, lib. viii, c. 40.) It appears to have a near connexion with the smooth varieties of the German boar-hound. 2. The Lesser Dane, Dal- matian, or Coach Dog, he Braque de Bengal, Buffon, is a beautiful animal, regularly spotted over his body with black or dark blue spots on a light ground. In form he is between the hound and pointer, and without doubt might be cul- tivated into the one or the other. Bewick is severe on Buffon, under the idea of its incapacity of scenting game. But to give validity to his criticism, he should have proved that it. wanted the faculty, which I make no doubt was as inherent in him as in any hound whatever. It had not been taught the pur- suit of game, and was therefore not impressed with the ardour. Had Bewick confined his objection to the locality chosen by Buffon, that of Bengal, where a-dog of his markings is not common, he might have had reason. 11 The Irish and Scotch greyhounds, Can. grains Hybernicus, Ray, et Scoticus, Fleming, do not differ materially from each other, and both un- questionably own the same origin, and are synonymous with the German boar- hound and wolf-hound: as is well known, they are ronirli wire-haired dogs. Such as I saw in Ireland were majestically large, and united considerable speed with immense strength: they were of a light grey colour, with a mixture of yellow or fawn-coloured tinting. A century back, the Irish wolf dog, it is said, was nearly four feet high. The Marquis of Sligo is among the few who B 20 NATURAL HISTORY OF THE DOG. c, Russian greyhound12; d, Italian greyhound13; e, Turkish greyhound14; to which should be appended the smooth or modern greyhound, Lepor arias, Fleming15. preserve this race, which he does at Westport, in the county of Mayo. The Scottish greyhound, deer-dog, or ratche, is somewhat less in size than the Irish ; at least such as I have seen more resemble a strong, coarse wire-haired true greyhound ; but which, probably, depends on the deterioration of inter- mixture : for it is said that a few yet exist in the Highlands of nearly the same proportions with those of Ireland. Captain Brown, in his interesting Biogra- phical Sketches of Dogs, informs us that Capt. Macdonell, of Glengarry, a gentleman remarked for his attachment to whatever characterizes the sports and customs of former times, keeps up this breed; an;l in order to preserve it from degenerating by consanguineous origin, he crosses them both with the blood-hound from Cuba, and the shepherd's dog of the Pyrenees ; which latter is distinguished for its size, beauty, and doc.lity. Sir Walter Scott's cele- brated dog Maida was of this breed, and is said to have been a most noble animal. The boar-hound of Germany is not, however, of necessity a rough- coated dog, for it is more than probable that he derives his origin from the great Dane ; whereas the rough-coated may be presumed to have drawn his from intermixture with some of the larger northern varieties, as the Siberian, Esquimaux, &c. ; all of which are guarded with a thick curled coat. 12 The Russian greyhound is not unlike that of Scotland, and possesses much agility. It remains to remark, that under whatever name this variety passes, whether of boar-hound, or of Irish or Scotch greyhound, it is a dog gifted with an excellent sense of scenting, and is equally brave, gentle, and affectionate: when, therefore, naturalists take on themselves to attach certain qualities to certain structural peculiarities only, as exquisite sensibility of smell, inherent sagacity, and devoted attachment to one group only, they limit nature within bounds she does not own. 13 The Italian greyhound is a pigmy variety, of elegant form, but timid, sensitive, and tender in the extreme. 14 The Turkish greyhound is even smaller, hardly so slender, and is fre- quently naked. 15 The modern or smooth greyhound is wholly a factitious animal, and ex- hibits, in a wonderful manner, the power of cultivation. In early times this dog hunted as well by scent as by sight; and with such qualifications he must have proved very destructive to the larger kinds of game, as deer, wild goats, foxes, &c. Such a dog was the gazehound, of whose extraordinary powers in selecting and keeping his game in view we have many accounts. But as the larger varieties of game became scarce, or was principally hunted by packs of hounds, so the use of the greyhound became confined to the taking of the hare. To do this, however, effectually, the arts of cultivation and selection were called into practice, thereby to produce an increased celerity of motion, by a corresponding alteration in the form of the machine. The head was rendered flat and pointed, to offer less resistance to the wind, and to subtract from its weight: the chest was considerably deepened, somewhat at the ex- pense of its general circular capacity, but without wholly destroying its seg- NATURAL HISTORY OP THE DOG. 21 2. SPANIELS. Anatomical character : " The head very moderately elongated ; the parietal bones do not approach each other above the temples, mental flexure of rib; by which respiration could be increased, although both weight and resistance were decreased. The abdomen became wonderfully contracted, and its intestinal contents so devoid of all interstitial matter, as to offer little obstruction to the momentum of the machine, and little obstacle to the dilatations of the diaphragm. The extremities were at once fined and greatly extended, and their angles rendered capable of great extension by lengthening those portions which were principally concerned in propelling the machine, and shortening those which operated more in support than progression: thus it is with the greyhound, as with all animals of great speed, that the knee and the hock are both placed by nature very near the ground, dependant on the curtailment of the intervening portions. The mus- cles of the back, loins, and thighs in the greyhound are singularly large; and thus all these advantages of the bony mechanism can be assisted by an increase of moving power. But, that this increase of velocity gained might not destroy the equality between the pursuer and the pursued, which is an invariable law in nature, it followed that the head becoming long and pointed, occasioned such contraction of the frontal sinuses as to injure the sense of acute smell, and to annul the power of following the game by scent; and the greyhound is therefore now forced to trust to his vision alone, which at once brings him and his prey more on a par with each other. This cranial alteration appears also to have some effect on the faculties of this dog, by lessening the aptitude to education, and confining the general intelligence ; but it does not do it in the degree that some naturalists would imply. The descent of the modern grey- hound is not distinctly traceable ; but it may reasonably be conjectured to be derived from the smooth variety of the wolf or boar-hound, rendered fine by transportation into warmer climates. Its name is said to be of Grecian origin : the race is certainly a very diffused one, and although we have the merit of having cultivated it to its utmost extent, as regards its celerity of motion, it is by no means exclusively English. In the Levant it is very common. In Turkey we have the authority of Mr. Dallaway for asserting that the grey- hound is common, and that there they are large and white, with their legs and tails fantastically stained with red. In Laconia they are, according to Mr. Hobhouse, also large, and their hair long. The long-haired greyhound is therefore by no means confined to northern climates ; neither are long external coverings of hair among other domestic animals uncommon in the warmest countries, as we see in the cats, rabbits, and goats of Angora ; but the hair so seen, however long, possesses a silky fineness of texture, and does not retain animal heat as does the thick, wiry hair of northern animals, with a matting of wool at the roots. The greyhounds of the east, although delicately fine in their limbs, have many of them long silk-like coats. The elegant animal called the Persian greyhound, to the utmost lightness of form and smoothness of body adds the peculiarity of having his ears, legs, and tail, befringed with very long fine hair, like that of the setter or spaniel.

For a more full account of this important variety of the canine race, I would recommend the reader to a Treatise on Greyhounds, attributed to Sir Wnr Clayton, a Baronet of sporting celebrity. In this elegant and classic produc- tion will be found a fund of interesting and instructive matter relative to the breeding, rearing, and treatment of these dogs. According to the modesty of its author, it is besprinkled with " a few classical flowers ;" but the reader will find it a gay parterre, where literary and sporting subjects change hands at every turn. 16 King Charles II, it is known, was extremely fond of spaniels, two varieties of which are seen in his several portraits, or in those of his fa- vourites. One of these was small, of a black and white colour, with ears of an extreme length ; the other was large and black, but the black was beautifully relieved by tan markings, exactly similar to the markings of the black and tan terrier: this breed the late Duke of Norfolk preserved with jealous care. That amiable and excellent lady, the Princess Sophia of Gloucester, shewed me a very line specimen presented to her by that nobleman, after receiving a pro- mise, guaranteed by her royal brother, that she was not to breed from it in a direct line. Another was shewn to me by the late Lady Castlereagh, received after a similar restriction. Even the Duchess of York could not obtain one but on the same terms, as she herself informed me. 17 No dog presents such endless varieties as the Spaniel; all, however, admit of two common divisions, into land and water spaniels : the latter are derived from the northern, the former from the eastern dogs. Land Spaniels are all characterized by a long silky coat; and whether strong and muscular, or slender and diminutive, they are equally elegant and interesting. They are proverbially faithful ; and to the sportsman they are highly important, from their keen scent and attachment to the pursuit of game. NATURAL HISTORY OF THE DOG. 23 Lin. is — Addenda, The Newfoundland dogW; The Alpine spaniel20. « The Setter is undoubtedly derived wholly from the spaniel, and not, as has been supposed, from a mixture of spaniel and pointer Robert Dudley Duke of Northumberland, is recorded as the first person who broke (to the net) a setter (i. e. a spaniel), so called from its lying down before game until a net was drawn over both dog and game. After this aptitude had been displayed, ,t is natural to suppose that the breed would be continued, and future cultiva- tions increased its size and powers. The setter retained the name of spaniel until of late years ; and to this day he is caUed, in Ireland, the English spamel. Gay calls him the « creeping spaniel ;" Thomson, also, has How, in his mid-career, the spaniel struck Stiff by the tainted gale, with open nose Outslretch'd, &c. The old English setter is now scarce, and has given place to a breed of less docility and subjection, but of enlarged size and increased speed: these are mostly red, and are of Irish origin. The term Index, by which the setter has been known, it is evident is not more appropriate; indeed, it is less so than to the pointer. . w The Newfoundland dog, now so much cultivated among us, was, without doubt, originally received from the country he derives his name from; but whether he derives his original parentage from thence admits of much doubt; indeed, I believe it admits of an absolute denial. In all probability he owns a lineal descent from the large Spanish dog, introduced by the early dis- coverers of the American continent, which, intermixing with the native breeds, produced an increase of size and power among them. These would be en- couraged by the natives, because the uses they made of them as beasts of draught were thereby better fulfilled. Such, we have reason to believe, was the first improvement made on the native dogs of these countries, which, as iar as a factitious breed can continue its like, seems to have remained a standard anion- them ever since, and is that which forms the smaller smooth aquatic dog of Newfoundland. When the English settled themselves here, they, with- out doubt, carried with them some of the largest and most powerful of the water spaniel breed, to assist them in the hunting and shooting of wild fowl ; and there is little reason to doubt but that this was the source from whence our admired specimens of the large Newfoundland dog arose; the breeding of which, however, was never carried to any great extent in that country. The rigors of the climate, and the difficulty of procuring food for it during some seasons of the year, were unfavourable to both the production of numbers and to the full development of the frame. The splendid animal we now see lias been greatly increased in size since its residence among us : we have culti- vated it so as to make it now an English breed, while in Newfoundland it. is at present so nearly extinct, that a gentleman relates, in No. 123 of the new series of the Sporting Magazine, that he could not find a single dog of the kind in St. John's. It is, therefore, a fallacy for naturalists to assert that the dog we possess is the same with that which is " employed in their native districts in place of the horse." 80 It appears to mc a complete misnomer to call this a spaniel. It is not 24 NATURAL HISTORY OF THE DOO. Var. F — The Water Spaniel, Cants aquaticus, Lin.; chien bay-bat, Buff.

Essentially this is the same as the blood-hound. The older varieties of the hound were all designated by the term Talbot, which term is, however, now often applied to the blood-hound, he being, with the exception of an occasional pack of harriers of the old growth, the only hound left with heavy limb and long pendulous ears.

It is too heavy for the purposes of hunting, audi believe betrays no propensities of this kind; but it is in every respect a mastiff', possessing all the qualities of our dog so called, and his appearance likewise, with the exception, that the upper lip is less pendulous, and the face altogether shorter. Mr. Griffiths has much curtailed its dimen- sions when lie gives the height as two feet at the shoulders. There is extant an engraving, made from a portrait taken by Mr. Edward Landseer, of one which at a year old was six feet eight inches in length from the nose to the end of the tail, and two feet seven inches in height at the shoulders, at which time he must have had some inches to grow. I saw, some years ago, two of these dogs, of size nearly equal to this, and of the usual colour, which is a tawny, between red and yellow. 1 The Terrier. It is by no means easy to trace the origin of this useful and interesting race, which is branched out into endless varieties. In The Farrier and Naturalist, No. 10, it is said " that the terrier's name appears to be derived from his entering holes in the earth after his game, and from the minute description given of him in Oppian's poems, who lived in the days of Severus, A.D. 194. It is certain that the breed has been long known in this island, and so far appears to have been an original native. Linnaeus states it -was first introduced on the continent, so late as the reign of Frederic the First." I cannot, however, agree with what follows,— that it is probably the vertagus or tumbler of Raii, and some other writers, which was, I belic\e, a very different variety ; nor am I aware that any of the true terrier breed has discovered the smallest propensity to this stratagem. The qualities of the terrier are to the full as diversified as his form: he may be taught to do any thing that dogs do, and to assist in the pursuit of every species of game ; but his instinctive propensities are directed to the destruction of what is called vermin, as badgers, polecats, rats, mice, &c. The rough terriers are usually grey or white; the predominant colour of the smooth kind is jet black, vpih elegant tan markings.

I am not aware that any sporting dog, of the markings of the Dal- matian which follows our carriages, is used in India. It is true there is a small variety of pointer, spotted, brindled, or pied in the colours of the Dalmatian; but I do not know whether that has ever reached India ; still less likely is it to be used as a sporting dog.

K — Shepherd's dog, Can. fam. domesticus, Lin. ; Le chien de Berger, Buff.2 2 Notwithstanding the great variations in size met with in the pasture or shepherd's dog, in different countries of the globe (for he is probably the most extensively diffused of the race), yet he everywhere preserves some personal characteristics, which mark Ins adherence to the original type in a greater degree than in any other race over which man has so arbitrarily exercised his dominion. One of these is, his quantity of covering, which is invariably great, particularly about the neck. In temperate climates his coat is long and shaggy ; in cold ones it is coarse, and crisped or waved in minute curls ; in arid regions his hair is still long and shaggy, but fine. In Britain it is remark- able that we have resemblances of all these varieties, as witnessed in the large drovers' dogs which attend the beast markets; the true shepherd's dog of South Britain, and the sagacious colly of North Britain. The ears are never entirely pendant in any of the race; but in the British varieties, and many others also, are half erected, or half pricked, as it is called. The colour is also very generally grey, more or less dark. The natural tail of the British breeds is bushy, somewhat pendant, and recurved, such as is seen in the colly ; but in England a custom has so long prevailed of cutting off the stern, that many of these dogs are now actually born with less than half a tail; which serves to shew how even the bony structure also, in other instances the most permanent of the whole, bends to circumstances arbitrarily imposed, and con- tinued with regularity. The visage of the shepherd's dog is more or less pointed; in the colly it is much so; but in the large drover's dog of South Britain it is much less : this latter dog is remarkable for seldom trotting or walking, but, on the contrary, he paces either fast or slow. The whole race have the additamcntary toe, or dew-claw of the sportsman.

The origin of this dog is difficult to trace, particularly from the sources pointed out by the naturalists of the last century ; yet if we direct our attention closely to the subject, we shall detect a very near resemblance between him and some of those specimens derived from Australia and high northern latitudes, but which, it may be observed, differ among themselves; the dog used to prevent the destructive attack of wolves on the rein-deer, and which drives them to the fold, being, we are told, not the same with that used about the Mackenzie river. 3 Linnseus seems to have fallen into much error in naming this Molossus; but his error was less than that of Buffon, who considered the bull-dog to be the parent of the mastiff, itself originating in the alteration which a temperate climate had wrought on his universal progenitor, the shepherd's dog. In my present opinion, for I once thought differently, the bull-dog is either imme- diately derived from an accidentally sltmted variety of mastiff, which sup- position the outward bending of his fore-arms, and general contortion of limbs, as well as the projection of his lower jaw, would favour, by bespeaking a ricketty constitution ; or otherwise he may have been mediately brought about, and not improbably, according to the supposition of the late Sydenham Ed- wards, who to much acquirement as a naturalist added a particular attach- ment to this dog. He is of opinion that he is derived from an accidental or designed mixture between the large mastiff and the pug-dog, which was then known as the Dutch, or small mastiff; and which, it must be observed, is by no means, in Holland, Germany, &c, the artificial animal we rear ; but, on the contrary, as I have seen it there, is much larger and fiercer than our degenerate race : and it must be allowed, that a progeny derived from it in this form, by means of the mastiff, might soon be cultivated into the bull-dog. That the origin of the bull-dog is wholly artificial is evident; for such a dog «:ould not live in a slate of nature; and that he draws this artificial origin from NATURAL HISTORY OF THE DOG. 27 Var. Q — The Mastiff, Can. fam. Anglicus, Lin. ; Le dogue de fort race, Bull'.1 British cultivation, is equally so, from the degeneration which invariably takes place when he is transported into distant countries. There is a brutal courage about this dog, called forth on the slightest excitement, as an accidental noise, &c, which particularly characterises the breed; and its frame is eminently formed to retain the hold it takes of any thing, by the recession of its nostrils, which do not thus interfere with respiration, as well as by the power with which its masseter muscles can act on jaws whose place of seizure are so little removed from the centre of motion. Mr. Griffith observes, " The in- ternal changes which determine the external characters of this dog, consist in a great development of the frontal sinuses, a development which elevates the bones of the forehead above the nose, and which leads in the same direction the cerebral cavity. But the most important change, and that perhaps which causes all the others, although we cannot perceive the connexion, is the diminution of the brain. The cerebral capacity of the bull-dog is sensibly smaller than in any other race ; and it is, doubtless, to the decrease of the encephalon that we must attribute its inferiority to all others in every thing relating to intel- ligence. The bull-dog is scarcely capable of any education, and is fitted for nothing- but combat and ferocity. A fifth toe is occasionally found, more or less developed, on the hind feet of this race. This, like all other races far removed from the primitive type, is difficult of reproduction; the males are seldom amorous, and the females frequently miscarry. Their life, also, is short, though their development is slow : they scarcely acquire maturity un- der eighteen months, and at five or six years shew signs of decrepitude." * Mr. Griffiths derives the mastiff from the bull-dog, which appears to me most erroneous, the latter being a dog of much later date. The mastiff is a straight-limbed dog, his lips are characteristically pendulous in a much greater degree than the bull-dog, and he is never underhung, and seldom has dew- claws, which are so common to some breeds of the bull-dog. His tail also is longer, thicker, and less tapered, and seldom carried erect. Buffon forgot the antiquity of this dog when he attributed its origin to the bull-dog and the Irish greyhound ; nor is it likely, considering the known tendency in the bull-dog to degenerate, that he would be so extensively diffused, and so readily preserve in this wide diffusion his hereditary form and qualities. Wherever he is met with, he is nearly the same, whether it be in the Alps, in Poland, Sweden, Italy, Spain, or the Levant. As he extends into warmer countries, how- c\ er, he becomes rather more slender; thus the mastiffs of Cuba, in the Zoo- logical Gardens, approach the old Spanish pointer in figure. The breed of mastiffs was, in "olden times," an important branch of British commerce; and when this island was under the Roman yoke, these dogs were in such re- quest, that an officer was appointed, under the name of Procurator Synegii, to superintend the breeding and transmitting them to the Roman amphitheatre. Straho tells us that these dogs have been trained to war, and were used by the Gauls against their adversaries. As a guard, there is no dog whatever that can supersede the mastiff; but unfortunately the beauty of the Newfound- land dog has almost done this, and the change lias not been a fortunate one ou 28 NATURAL HISTORY OF THE DOG.

The detail I have already entered into is of itself, I should the score of trust. The mastiff is vigilant in the extreme, and no less cautious than watchful : in prosecuting his duty, he is silent as a sentry ; and while there is no danger he appears as monotonous and indifferent to all around him ; and under such circumstances it is difficult to decide which of the two is most like an automaton. But a suspicious footstep made with caution is instantly heard, and as instantly but silently watched and attended to. An ill-looking per- son is not molested, but is followed as far as the precincts of the guard extend ; and so long as nothing is touched, the intruder is safe ; but no longer. Even then he is seldom injured ; sometimes he is merely led out ; and unless resistance is offered, few lacerations have been received from this formidable but generous beast. What would I not have given to have seen the one which was found standing over a robber who had broken into a yard at Islington ! The owner was called up by the watchman, w ho informed him that, " by the bustle he heard in his yard, something was going on wrong there." It was the brave mastiff, who had siezed the thief, had thrown him down, and had been stand- ing over him, it appeared, two or three hours : as long as the man remained quiet, the dog did not even threaten ; but the moment he stirred only, a tre- mendous growl informed him he had better remain still. There are not ninny Newfoundland dogs which would have exhibited this forbearance; yet they are also brave and generous, but being more uncertain, are very inferior as direct guards for important trusts. The mastiff never sleeps on his post, the New- foundland dog does ; lor he is a lively fro!icksome creature, who is much in action, even when chained up; and therefore when night comes he sleeps. The mastiff has been for ages employed as a guard ; and therefore, like the watchman, during the day he sleeps, as a part of his nature and duty : neither has he any pleasures to pursue ; but, like the shepherd's dog, all his propen- sities merge within his business. I have somewhat dilated on this matter, be- cause I think the threatened extinction of the mastiff is an unfortunate circum- stance in commercial, rural, and domestic economy. NATURAL HISTORY OF THE DOG. 29 hope, confirmatory of the originality of the dog-, as tending to shew that he differs essentially from every other member of his genus. In the specific differences quoted by the authorities which have been noticed, there appears no mention of what may be, with justice, called special characteristics, as never appear- ing in any of the other species. The tail of the dog always takes an arched direction, and it always likewise, I believe, inclines to the left : whenever also any white is present about the body, the tip of the tail is sure to be of the same colour. Of the caninae, the dog alone has offered himself for domestication; and had there not been insuperable objections to the others, the enterprize of man would undoubtedly have attempted it. The bark of the dog is certainly an additional trait in his character, but it must be allowed to be not of much force, seeing that it is not invariably attached to them : all wild dogs are more or less mute, and some half-reclaimed ones howl only. The originality of the dog, there- fore, ought not, I conceive, to be any longer considered as ques- tionable. Nevertheless there are authorities of much weight, who attribute to him either a mixed or a spurious derivation. Mr. Wilson says, " Many well known varieties of the dog exhibit so wolfish an aspect, that their descent from that species can scarcely be a matter of doubt." Although this similarity in some is true, as it is also that these two species have intermixed, and have produced prolific offspring, yet when it is well known that in a state of nature the utmost abhorrence to each other exists, I cannot admit that such can be a frequent, although 1 am not able to deny its being an occasional, source of some mixed breeds, but to the perpetuity of which I should be very sceptical. The real identity between the dog and wolf is farther contradicted by the angular form of the bony assemblage of the head of the wolf ; the auditory portions of his temporal bones are likewise placed higher, and more anteriorly in the skull ; the orbitary fossas are more inclined, and his teeth are longer, stronger, and present some differences in form ; his cubitus is longer and more obliquely placed than the dog's, and his tail is always pendulous. NATURAL HISTORY OF THE DOG. The fox differs essentially from the dog, in being a solitary nocturnal animal, and in having a specific formation, to assist his vision at night, in the linear direction of his pupil ; his teeth also differ in direction ; and though the intermixture between him and the dog has been forced, it has been an unnatural one ; nature having in them, as in wolves, marked their want of identity by a settled general aversion. The character of the fox has none of the traits of the dog ; no efforts have been able to wholly reclaim him : the suspicious watchfulness and the sudden treachery of a predatory animal, never wholly leave him. He is also, to a cer- tain degree, like the chacal, mephitic throughout his numerous varieties, and which property is so purely vulpine, that it is not, I believe, imparted to his bastard progeny. The modulations of voice of the fox, throughout its variations, are totally unlike that of the dog : also he whines continually. To the hyena as a parent of any variety of the dog, although the notion is entertained by Pallas as the origin of the mastiff, it may be objected as most un- likely : the hyena is of a totally distinct genus, and the union, if effected and productive, could not, by the usual laws of nature, have become perpetuated. Guldenstaedt attributes some of our dogs to the chacal or jackal, and details their proofs of identity5. Pallas, too, is of a similar opinion ; and also asserts, that the Kalmuc dogs are neither more nor less than jackals6, and the remainder he appears to think derived from spurious sources?. 5 " Oderat anum altering ; coha;ret copula junctus."— Nov.

NATURAL HISTORY OF THE DOG. 31 Mr. Wilson's opinion seems to lead to a supposition that the chacal may be regarded as the true wild dog, and as such, the true source probably of most of our domesticated dogs. Fortu- nately for the claim of the dog to the honour of an original and specitic formation, this theory, otherwise very specious from the great similarity of structure between the two animals, loses its principal force, as is indeed admitted by Mr. W., when we reflect that this origin cannot apply to the wild dogs of New Holland, nor to those of North and South America, where, not- withstanding the assertions of Father Gili, Humboldt has clearly proved the dog to have been known long before the first visits of Europeans. In these countries, at least, we must look for another origin for the dog ; which Pallas has supplied by deriving the larger tribes, as the mastiff, &c. from the hyena, and the terrier from the fox. Mr. Wilson has very successfully combated these immediate origins ; but he is equally convinced with them that some of our larger breeds are derived from the wolf. As regards the identity of the dog with the jackal, there can, I think, be but one opinion, when we consider the circumstances of the limited geographical distribution of the latter animal. It is well known that he is formed for warm regions only : in the colder he never multiplies, with all the care man can bestow on him ; and near the tropics no art can even keep him alive. He is physically designed for a high temperature, and cannot be natu- ralized by art, like many other animals, to a cold one : it would be most irrational, therefore, to suppose that he would be chosen as the progenitor of an animal so widely diffused, north, east, west, and south, as the dog. There are also, if not great struc- tural dissimilarities between the animals, yet some distinctive marks of much weight. Like the fox, although it may in its own country be sufficiently tamed to allow of being handled, it sub- mits from fear ; but no kindness, however long continued, can inspire confidence in it. It also emits the most offensive odour, which it does not, like some of the mephites or skunks, lose under domestication. The dog, therefore, may lay claim to a true ori- NATURAL HISTORY OF THE DOG. ginality of general character, which is sufficient for my present purpose. But whether some of his endless varieties may or may not have arisen either from his own intermixture with some of the nearly allied species, or have resulted from intermixtures between these allied species themselves, my limits will not allow me to inquire further than by glancing at the agencies of climate and domestication ; which if they have not themselves originated these variations in size, form, and character, may yet be shewn to be fully equal to account for the diffusion throughout the world from one original type. Both sacred and prophane history have united in deriving man from Asia, where we also find some of the most valuable of his domesticated animals, as goats, sheep, dogs, &c, still existing in their primeval state. If man, therefore, found the means of transporting himself over the face of the globe, it may be sup- posed he would be accompanied by these his dependents ; and if man himself owes his variations from what must have been his original type to the interventions of climate, diversifications of food, and altered habits, it is most rational to suppose similar alterations might take place in the animals he fostered. But it might be expected, as it is found to have happened, that among them the varieties of form, colour, and properties, would be more nume- rous and remarkable ; because, in addition to the effects of climate, man assumed the direction of all their energies, the selection of their food, and the regulation of their sexual intercourse. Even climate alone is equal to produce wonderful changes on animal bodies. In ourselves it begets the extremes of white and black in the colour of our skins within the tropics ; while extra-tropical shades ranging between, mark the degrees of heat and cold. Most of the animals of high northern latitudes become of a lighter hue, as winter approaches, from a similar principle of adaptation with that which also increases the quantity of their clothing ; the light colour preventing the natural heat of the body escaping by the active radiation which occurs from bodies more darkly clad. The alteration in the general texture of these coverings, by the NATURAL HISTORY OP THE DOO. 33 effect of climate, is no less remarkable than that produced on their colours. In the sterile and inhospitable regions, where ice and snow hold a stern dominion, the quadrupeds are furnished with a short fleecy tegument, which is rendered still warmer by either a long and shaggy, or a short and crisp surtout of strong hair. The feathers of alpine water fowl conceal an immense mass of the warmest down underneath, while the land birds of these regions are feathered down to the very claws. To further exem- plify the effects of climate, observe how different are the clothings of the thick-fleeced dog of Baffin's Bay and the naked dog of Bar- bary ; the dense woolly covering of the European sheep, and the thin hair of those inhabiting hot countries. Contrast the glossy tunic of the Arabian stallion with the shaggy coat of the Shetland pony ; and further, it may be observed, that where, for the pur- poses of beauty, nature has bestowed on the beasts of arid climes a long coat or covering, it is commonly observed to be one whose thin and silky texture can neither absorb the solar ray3 nor con- fine the animal heat : this may be seen in the lengthened fine hair of the goats, cats, and rabbits of Angora, and other eastern countries. Our domesticated animals are even under the in- fluence of climate, and, as winter advances, they are seen to change their thin fine hair for one of longer and thicker texture. Our horses in autumn prepare for the coming season, and change their fine summer coat for one thicker and longer ; but, under an artificial climate produced by hot stables and extra clothing, by losing the stimulus of necessity, they retain the same appearance throughout the year. Neither are the coverings of the body the only parts that are subject to the effect of climate ; the form and bulk also are equally affected by its operations. By its powerful agency, varieties the most disproportionate are produced. Com- pare the eastern pigmy horse, scarcely thirty inches high, and the diminutive ponies of Shetland ; compare these with the stately coach and cart horses of England. Place together the gigantic urus of Lithuania ; the monstrous bison of America, with his shoulders surmounted by an enormous lump of flesh ; the mild 84 NATURAL HISTORY OF THE DOG. zebu of Africa; the musk bull of Arctic regions; the European ox, and the dwarf bull of India, not higher than a young Eng- lish calf; having so done, the extremes of size and dissimilitudes of form and character will leave us in astonishment at the num- ber and variety of Nature's works. If we carry on the compari- son to sheep and swine, we shall find the effects of climate as apparent on them as on the horse and ox. In Africa, the sheep are found swift, tall, gaunt, and even bold, with a pendulous dewlap. In Turkey, they are seen with a fleshy rump entirely disproportioned to the other parts. In Persia, this disproportion is translated to the tail, which is said, in some instances, to weigh fifteen or even twenty pounds. In Iceland, sheep are found with three or more horns ; in Wallachia, with two only, but those are long and spiral ; and in Kamtschatka they also have horns of an enormous length, but without convolutions. In northern countries the sheep are diminutive ; but in temperate climates they arrive to a great size and weight. In swine, the variations, in size at least, are equally disproportionate. In England the hog has at- tained to the following extraordinary proportions : length, three yards eight inches ; height, four feet and a half ; weight, seven hundred pounds. In China, on the contrary, he measures from eighteen to twenty inches in height, and in some parts of India he is still smaller. In Piedmont, swine are black ; in Bavaria, red ; and in Normandy, white : and, as a further proof of the effect of locality on them, it is observed, that the breeds originally re- moved to Cuba are become twice as large as those first taken there. Need we, therefore, seek for a varied parentage for the dog, although a specimen is shewn in the Dresden Museum, that at its death, which occurred when it was two years old, measured only five inches and a half in length, the precise extent from the corner of the eye to the tip of the nose of the great Saxon boar-bound. Man himself has varied from two feet to eight and a half in his height. Domestication is no less an important agent in the alterations it produces on those animals, because it subjects them to have NATURAL HISTORY OF THE DOG. 35 their food selected, their exertions forced or restricted, and their temperature raised or diminished at the will of the owners. Variations produced by these united means would offer to man the temptation of perpetuating them, which he would do by re- gulating the sexual intercourse, and propagating from such dupli- cates only as approached a given form. In other instances an accidental variation occurred, or a singular deformity was seized on and propagated by future similar selections, until it became permanent, and then it constituted a breed. To something of this kind we owe the wry-legged terriers, so useful in the shooting of rabbits. It is probable, also, that a crooked mastiff offered the foundation for the bull-dog breed. I have thus far principally treated of the form and varieties of the dog : I would fain say something of his qualities also, that I might thereby more effectually advocate his cause ; and that, by exciting inquiry into his real character and virtues, I might awaken a due consideration for him in the minds of those (of whom there are but too many) who now regard him with indifference, perhaps with contempt, or it may be with aversion. It is proba- ble that such feelings arise, in many, less from the natural im- pulses of the heart, than from a mistaken opinion of the actual rank that these animals ought to hold, by their services, their en- dearing qualities, and the entertainment they afford. If it were customary to consider the higher orders of brute animals in gene- ral not as mere machines, endowed with instinctive faculties only for the mere preservation of their existence and extension of their species ; but, on the contrary, if they were universally regarded in their true light, as beings higldy intellectual, actuated by the noblest passions, endued with memory and recollection, disposed to imita- tion, profiting by experience, and acquiring skill from discipline and instruction, then we might hope to see them properly estimated, their importance acknowledged, and their treatment amended. The properties here detailed are, in some degree, common to all ; but in the dog they shine with a lustre that none but those who study the animal can be aware of. We owe something also of the con- 30 NATURAL HISTORY OF THE DOG. tempt in which dogs arc held to the figurative language derived from eastern writings, both sacred and prophane. " You dog! " is a common term of reproach used towards those, as well as by those, who have not half the virtues of one; yet in uninformed- and in unrellecting minds, this metaphoric sarcasm serves to be- get contempt, both for the original and the portrait. Our oldest writers, with whom every thing vile and base is doglike, are full of this imagery. Even the sacred writings, abounding in the sublimest precepts of humanity, have added their share of obloquy and reproach, which sinks deep in many minds, and begets a tra- ditional contempt and ill-will towards one of the most deserving animals of the brute creation. To combat these popular sources of inhumanity, I have before observed, no means seem so well calcu- lated as to place the subject of our inquiry in his proper point of view, which is not that of a mere instinctive machine, but that of an intellectual being, and that of one who uses his mental and bodily powers principally for the good of mankind. For the rationality of the dog I am almost ashamed to contend, the proofs are so numerous ; and yet there are those who deny it hiin, in the face of the ablest philosophers and metaphysicians, who have clearly allowed him this distinction ; but the extent of his reasoning powers has occasioned great diversity of opinion among them also. Much, however, if not all, of this discordance has arisen for want of a precise idea of that inherent property we name instinct, under which general term it has been too common with writers to include the phenomena of reason. It is foreign to my present purpose, if it were within the reach of my ability, to enter on a metaphysical inquiry into the faculty of reason. It will be sufficient if I attempt to analyse the property of instinct : in doing which, if I should be enabled to prove that innumerable actions performed by dogs are not at all referrible to this qua- lity, I shall have compassed my object ; for if such actions are not instinctive, they must be rational. Instinct may be defined to be, that property in animals by which such actions are performed as immediately tend to the pre- NATURAL HISTORY OF THE DOG. 37 servation of themselves and the propagation of their species. It is a principle that may be considered as inherent in the organiza- tion of an animal body, by which, without instruction, de- liberation, or experience, it is urged to do whatever is im- mediately necessary for its self-preservation, and the conti- nuance of the species. It develops itself (contrary to reason) in full perfection as soon as it is wanted. The young chick, the moment it is disencumbered of its shell, dexterously picks up its food, and judiciously selects it from extraneous matter. The indigent and blind puppy, immediately on its entry into the world, searches out the mammillary processes that yield its nutriment, and adapts the surfaces of its little mouth to ex- haust the gland, with more dexterity than the most acute philoso- pher aided by every mechanical principle could do. The opera- tions of instinct being directed to the preservation of existence and the continuance of the species, it was necessarily given per- fect, or these ends would not have been answered ; but as its operations seem confined wholly to these great ends, so it is very limited in its scale of action, and admits of little, if any, improve- ment. In domestic as well as in unreclaimed animals, such actions as are directed to the essential laws of preservation and propagation remain always alike: the same general aptitudes, the same dexterity in catering for their food, excluding their enemies, and fostering their young, were as apparent two thou- sand years ago as at the present day. The instinctive princi- ple, as a purely preservative one, was originally given to them perfect ; it therefore required no extension, and it has received none. If this definition of instinct should be considered correct (which the more I consider the matter the more I am convinced that it is so), it will require but little observation on any of the higher orders of animals around us, but of quadrupeds particu- larly, and of these the dog more especially, to force conviction on our minds, that innumerable actions are daily performed by them, all of which are totally unconnected with either of these c2 38 NATURAL HISTORY OF THE DOG. great instinctive principles. It must be, therefore, self-evident, that all such actions must be extra-instinctive, and the result of rational operations of the brute mind. In the dog- these intel- lectual phenomena present themselves in infinite variety, and the impulses whereby they are directed seem equally diversified ; but my limits will not allow me, in this edition, as in the last, to bring forward illustrative anecdotes in proof of these positions ; and they are the less necessary, as most of them have been copied into various publications. A very excellent collection of this nature has been made by Capt. Brown, and to the perusal of which I would strongly recommend any sceptic on either the utility, the virtue, or the intellectuality of the dog. He is con- fiding, and obedient in the extreme. His bravery is well known, and it is admirably set off by his mercy, which to a conquered or to a lesser foe is often very remarkable. Most faithful and dis- interested, no temptation can make him desert his master, or his property especially entrusted to him. In the exercise of these proofs of his fidelity, all danger is disregarded ; even the press- ing calls of cold and hunger are not sufficient to make him aban- don his duty ; and the pages of history are fraught with well- authenticated accounts, where actual starvation has overtaken him when thus employed. This is no exaggerated picture, but a true portrait of the Dog as he is usually found, and the very few instances of darker shadowing, universally frail as we are our- selves, ought not to lessen our due appreciation of the mass. Such being the case, can we treat an animal of his worth with too much consideration and kindness ? Are we not as well bound by duty as by interest, to foster him with care, to protect him from harm, and to administer to his wants in sickness ; and yet is he in general so treated? On the contrary, is he not neglected by one half of mankind ; and by more than a half of the re- mainder is he not despised and ill-treated ? Were it otherwise, pages written in illustration of his history ; on the cultivation of his varieties ; and the improvement of his talent, would be con- sidered as honourable offerings to society : neither would the NATURAL HISTORY OF THE DOG. 39 human surgeon, in turning aside from the higher duties of his profession, to describe the numerous diseases, and to detail suc- cessful methods of combating them in him, as well as in the horse, be considered as having, in the smallest degree, compro- mised either his professional or personal respectibility. It ill accords with the boasted ' ' march of intellect," that the study and improvement of any branch of philosophy should do other than elevate the professor of it. "They manage these things better in France." Justly convinced, that whatever is useful and humane is honourable also, this enlightened nation encourages brute medicine to the utmost, by the erection of colleges, the appointment of professors, and the granting of diplomas to its students, who then move in honourable competition and associ- ation with the practitioners of the parent art. PART THE SECOND. THE REPRODUCTIVE SYSTEM ; OR THE BREEDING AND REARING OF DOGS, THEORETICALLY AND PRACTICALLY CONSIDERED: WITH THE GENERAL TREATMENT OF THEM, BOTH AS PREVENTIVE AND CURATIVE OF DISEASE. THE breeding and rearing of dog's are important considera- tions, both to the rural economist and the sportsman : the sub- ject is also intimately connected with their medical treatment ; for there are particular diseases attendant on both mother and offspring while in a state of mutual dependance on each other. The reproduction of the animal form is brought about in dogs by desires that are not constant, but which among the wild breeds occur about once a year : in domesticated dogs, on the contrary, as shelter and nourishment under the fostering care of man are present at all times of the year, so the periods of their osstrum, or heat, return at uncertain intervals of six, seven, or eight months, as confinement or highly stimulating food may hasten the sexual excitement1. The heat or oestrum of bitches is the consequence of a sympa- thetic action between all the organs concerned in generation, 1 It has been attempted to bring on the sexual appetency or heat in bitches by stimulating injections, and it now and then succeeds: but as it is an un- natural process, and as the constitutional sympathy cannot be supposed to be so fully excited as to produce a general consent of parts, impregnation does not always follow the intercourse, and, when it does, the progeny are some- times ad'ected by it, proving weak and unhealthy. I once saw a litter thus artificially urged into life, where every one was ricketty. 42 THE REPRODUCTIVE SYSTEM. which at these times become more highly susceptible and vas- cular, as is shewn by tumefaction of the external parts, and a discharge from the vulva. There are likewise strong marks of general excitement throughout the body; the plethoric and irritable state of which is such, that those bitches that have been before subject to fits, are now peculiarly Hable to them ; and con- vulsions often appear at this time in those that have not before been affected by them. It is evident, therefore, that the precau- tions of cooling food, judicious exercise, and opening medicines, are necessary at these periods, for the young and delicate parti- cularly; and they are still more so for such bitches as are intended to be debarred from the dog; for, in these latter cases, their excitement remains long in action, when they are deprived of the satiety of sexual intercourse. Bitches should therefore be alloived to breed, nor is it good for their health to preArent it ; for nature almost invariably punishes extraordinary deviations from her estabHshed laws, of which the reproductive system is one of the most important. Breeding, therefore, is so much a healthy and necessary process, that bitches prevented from it rarely remain unaffected by disease, and more particularly those whose confined and luxurious lives espe- cially require the aid of such outlets to the superabundance of the system as are opened during the processes of breeding and rearing of young. In such, barrenness is particularly hurtful, and greatly assists in producing, sooner or later, enormous and diseased collections of fat either universal or partial. The par- tial collections frecpiently shew themselves by a swelling on each side of the loins> the consequence of a deposit of adipose substance around each ovaria. In other cases, particularly where barrenness is occasional only, the mamm*, or milk glands, become affected with small indurations; which are apt even- tually to end in confirmed scirrhi or open ulcers. See Scirr- hous Diseases of Glands, Class V. — A more immediate evil likewise often awaits the preventing of the sexual intercourse, which is, a troublesome accumulation of milk in the mammae, or teats ; for the various organs of generation have such a sympa- THE REPRODUCTIVE SYSTEM. 43 thetic connexion with each other, that when females are denied the doo-, still, when the customary period of gestation or going with young has passed, milk will nevertheless appear in the lac- tiferous glands. This sometimes occurs to a very considerable degree, and occasions much heat and distention. It is more particularly observed in such females as have already had young ones, and they invariably suffer most in the future privation. In such cases, it is proper gently to press out the milk daily, winch will greatly relieve the animal; the teats should also be fre- quently bathed with a mixture of brandy and vinegar a little weakened with water. Food should be given sparingly, and that of a vegetable nature is best; strong exercise should also be encouraged, and an occasional dose of physic will prove useful. The author of an elegant Treatise on Greyhounds (whose opinion, as an observant sportsman and breeder, ought to have due weight), remarks, that where breeding has been always prevented, he has never found any injurious effects whatever to follow from it. It is undoubtedly true, and it accords with my own experience, that the constitution having once been sub- jected to the reproductive process, or, in other words, that it is in those which have been once allowed to breed, that the injurious consequences are most observed; in every instance they are more liable to suffer from the future deprivation of it than those in whom the constitutional sympathies have never been fully excited throughout the generative system. It may also be remarked, in answer to the above statement, that sport- ing and other dogs accustomed to moderate feeding and regular exercise (which are evidently those Sir W. C. draws his in- ferences from), will bear this deprivation with much greater im- punity than those that are more confined and altogether more artificially treated. But as a law in the animal economy, and as one applicable to the general state and constitution of the dog, the reproduction of the species is a necessary, a natural, and, consequently, a healthy process ; and the theory is borne out by the fact for attentive observation extended to all the varieties oj the species, will shew, that the suffering of bitches to breed, not 44 THE REPRODUCTIVE SYSTEM. only tends to keep them in health, but that those which have been allowed to bring up numerous litters, have more invariably attained a great age than such as have been debarred the inter- course. It may be added, that the same is observed in the human, where the average of longevity among females is de- cidedly in favour of the married, compared with the single. Bitches in heat are very canning, and often elude all but the greatest vigilance in their attempts to escape in search of a mate ; and thus, for want of due caution, many frustrate the hopes of their owners in the desired breed ; and many others meet their death by becoming lined by a dog so extremely dis- proportionate in size that the mothers are found unable to bring forth. When, therefore, a bitch has so escaped, it will be pru- dent immediately to follow her ; not only to prevent the . inter- course altogether, but to guard against the brutal folly of boys and others, who, when it has taken place, often throw cold water over the animals, or tear them away from each other by violence. I have seen the parts of the female actually suffer inversion from this : other injurious consequences have also very frequently followed^. To the dog, likewise, it is no less hurtful, by fatally rupturing the bloodvessels of the parts3, or by other lacerations. Impregnation takes place sometimes at the first copulation, in others not until the second, third, or fourth ; and in some cases I a Brutal as is the practice of spaying in ordinary cases, it would be ad- missible, in an instance where it was known that a very favourite and very small bitch had copulated with a very large bony dog; for in such case, as little risk would attend the operation of spaying, judiciously performed at a proper time of the pregnancy, but extreme risk would be incurred by waiting the natural time of bringing forth, so it would be very proper to have it done. See Spaying, among the Operations, Class XII. 3 This retention of the male within the female parts after the act has been apparently completed, arises from a peculiarity of structure in both. In the male, the corpora cavernosa have two large lateral protuberances, which, when distended with blood, effectually retain the penis within the vagina of the female, till the venereal orgasm has entirely ceased. The clitoris of the fe- male also partakes of a similar structure, and firmly retains the penis in coitu by a protuberant ring, which then closes firmly on it. The same structure is apparent in all the canine congeners. THE REPRODUCTIVE SYSTEM. 45 have known, from decided proofs, that impregnation did not ensue until the seventh warding. Dogs should be suffered, there- fore, to remain together some days to insure prolific intercourse. This protracted period, however, applies more particularly to pampered and tender dogs ; those which five less artificially as sporting and rural dogs, conceive usually at the second or third warding. During gestation, dogs do not appear to suffer much derangement of system ; some, however, appear to be listless nauseated, and averse to particular foods; and most of them are more thirsty at this than at other times. It is not easy to detect whether bitches are in pup until the fourth or fifth week after warding ; about which time the teats enlarge, the flanks fill, and the belly assumes a fulness and rotundity unnatural to it at others. Towards the seventh week, the belly becomes pendulous, and the future increase is not so observable as the previous. In the last week of pregnancy, the contents of the belly seem to in- cline backwards, the vulva increases in size, and a slimy matter (to soften and lubricate the parts) often issues. Pupping usually comes on the sixty-second, sixty-third, or, at farthest, on the sixty-fourth day. A quarter or half an hour, and sometimes a longer time, intervenes between the expulsion of each foetus. 1 have known a solitary puppy appear on the seventieth day from the last intercourse, and that in a case where superfcetation was improbable. See Pupping. -During the pregnancy of bitches, particular care should be taken to observe, and to remove, any appearance of mange or other affections of the skin and surface : if this be neglected, the progeny will be brought into the world with an hereditary taint that no future endeavours can wholly eradicate. Dogs are certainly capable of superfcetation ; that is, impreg- nation may take place at more than one warding, and that by distinct mates. The fact was long ago admitted by naturalists and physiologists*; since which time numerous circumstances ,In the superfcetation of brutes, is there not reason to suppose that the Jrm i confuted from each ovaria in succession ? or do the ova or germs pVclt tnemselves indiscriminately from- both 7 The interestrng .xper.rnents of Dr. Haighton, related in the PhUosofhical Transactions, 17OT, p. 1S», 40 THE REPRODUCTIVE SYSTEM. have fallen under the notice of sportsmen that confirm the matter. I have, in several instances, seen whelps of the same litter with appearances which bore evident marks of different origin, and where the future disproportion in size, with all the distinctive marks of varied species, clearly evinced that more than one male was concerned in the process. Antecedent i?npressions received have often cm effect on the progeny. — Superfcetation is apt to be confouuded with, or its phenomena are sometimes accounted for by, another process, still more curious and inexplicable, but which is wholly dependent on the mother ; where imprintings which have been received by her mind previous to her sexual intercourse are conveyed to the germs within her, so as to stamp one or more of them with cha- racteristic traits of resemblance to the dog from which the im- pression was taken, although of a totally different breed from the real father of the progeny. In superfcetation, the size, form, &c. of the additional progeny all fully betoken their origin. In these instances of sympathetic deviation, the form, size, and character are, in most, principally the mother's ; but the colour is usually the favourite's, with, perhaps, a few characteristic blendings of ex- ternal resemblance intermixed. It would appear that this mental impression, which is perhaps usually raised at some period of oestrum, always recurs at that period, and is so interwoven with the organization even, as to become a stamp or mould for some if not all of her future progeny ; the existence of which curious anomaly in the reproductive or breeding system is confirmed by acts of not unfrequent occurrence. I had a pug bitch whose constant companion was a small and almost tvhite spaniel dog, of Lord Rivers' breed, of which she was very fond. When it be- came necessary to separate her, on account of her heat, from this dog, and to confine her with one of her own kind, she pined ex- cessively ; and notwithstanding her situation, it was some time and by Mr. Cruickshanks, id. p. 197, tend to throw light on this curious sub- ject. Superfcetation seems extended also to the human ; instances ol iliis un- recorded in Blumenbach's Institutions of Physiology, and in White's work on the Regular Gradation of the Human Race. THE REPRODUCTIVE SYSTEM. 47 before she would admit of the attentions of the pug dog placed with her. At length, however, she did so ; impregnation fol- lowed, and at the usual period she brought forth five pug pup- pies, one of which was elegantly white, and more slender than the others. The spaniel was soon afterwards given away, but the impression remained ; for at two subsequent litters (which were all she had afterwards) she presented me withawfo'fc young one, which the fanciers know to be a very rare occurrence5. 5 It is a curious circumstance, that each succeeding white puppy was less slender in form than the preceding, though all were equally white ; which shewed, as I have before stated, that this mental influence extends less per- fectly to the individual form, than to its external characters, particularly of colour ; and also that it lessens by time and absence. When, therefore, pups of completely different forms and kinds proceed from one litter, superfceta- tion has occurred, and not mental influence. The Rev. R. Lascelles, m his Letters on Sporting, p. 250, relates a case of a greyhound bitch, entrusted to the care of a servant, which whelped one perfect greyhound and six complete curs • the curs were the likeness of the dog she domesticated with in common ; the single one resembled the greyhound she was taken to during her heat. There is little reason, therefore, to doubt that the bitch had been previously lined by the cur, and the single greyhound pup was the effect of superfcetation. I mention this to shew how easy this mistake between two different causes may occur, and how they may be distinguished. I was not fortunate enough to rear either of my white puppies: the late Lord Kelly offered me fifteen guineas for one of them at three months old. Lord Morton bred from a male quagga and a chesnut mare. The mare was afterwards bred from by a black Arabian horse ; but still the progeny ex- hibited, in colour and mane, a striking resemblance to the quagga. D. Giles, Esq. had a sow of the black and white kind, which was bred from by a boar of the wild breed, of a deep chesnut colour : the pigs produced by this inter- course were duly mixed, the colour of the boar being in some very predomi- nant. The sow was afterwards bred from by two of Mr. Western's boars, and in both instances chesnut marks were prevalent in the litter, which, in other instances, had never presented any appearance of the kind. Phil. Trans. 1821.— The former cases tend to confirm what I have before remarked, that the mental influence excited on these occasions extends less to the internal or- ganization than to the external characters of colour and covering. The fol- lowing will, however, shew, that impressions from terror may sink so deep as to affect the organization also of the progeny. In the Linnamn Society of London is found an account, by Mr. Milne, of a pregnant cat, his own pro- perty the end of whose tail was trodden on with so much violence, as, appa- rently, to give the animal intense pain. When she kittened, five young ones appeared, perfect in every other respect except the tail, which was, in each one of them, distorted near the end, and enlarged into a cartilaginous knob.— Lin. Trans.., vol. ix, p. 323. 48 THE REPRODUCTIVE SYSTEM. The late Dr. Hugh Smith used to relate a similar instance which occurred to a very favourite female setter that often fol- lowed his carriage. On one occasion, when travelling in the country, she became suddenly so enamoured of a mongrel that followed her, that, to separate them, he was forced, or rather his anger irritated him, to shoot the mongrel, and he then pro- ceeded on his journey. The image of this sudden favourite, how- ever, still haunted the bitch, and for some weeks after she pined excessively, and obstinately refused intercourse with any other dog. At length she admitted the caresses of a well-bred setter ; but when she whelped, the Doctor was mortified with the sight of a litter which he perceived bore evident marks (particularly in colour) of the favoured cur, and they were accordingly destroyed. The same also occurred in all her future puppings : invariably the breed was tainted by the lasting impression made by the mongrel. It is, therefore, evident, that to ensure a select breed, too much care cannot be taken to render the choice of the male agreeable to the female ; and also, that where a female of a very valuable breed has been long habituated to any favourite male companion, and which it is not intended she should be allowed to breed by, that it is advisable to separate them even before the oestrum or heat of the bitch comes on, which will prevent the disappointment that might otherwise occur. Like begets like, is the dog-breeder's axiom ; and when the anomalies noticed do not interfere, the produce of a connexion between dogs of a similar breed usually exhibits traits of indivi- dual resemblance to each, united with the characteristic marks common to the breed in general. Sportsmen incline to the opinion, that the male pups are more strongly tinctured with the external form of the father than of the mother, and vice versa ; but though instances may occur to favour such conclusion, it is not a uniform occurrence. When the parents are of different breeds0, the varying outlines of each are usually softened and 6 When dogs of different breeds arc brought together, the progeny are said to be a cross. Thus, pointers are sometimes crossed With foxhounds, to in- THE REPRODUCTIVE SYSTEM. 49 blended in the progeny, in nearly equal proportions*. But this division of parental character is not always equal : it sometimes happens that the more notable characteristics of form, size, and qualities, and even of sex, are principally derived from the male parents. In others a stronger similitude to the mother is appa- rent; and it now and then happens that these partialities seem to crease their speed and ardour. The effect of these crosses is retained to the seventh or eighth generation: among turf sportsmen it is supposed to exist, in horses, to the twentieth successive descendant. 7 These hlendings of the individual character of each parent are illustrated by hybridous animals: how easily traced, and yet how blended into a whole, are the characters of the horse and ass, as observed in the hybrid mule ! These hybridous productions also completely disprove the opinion some physmlog.sts have formed, that the male parent, in the probative act, imparts nothing be- yond the mere stimulus of life to the ovum or germ of the female; tor it must he evident that the germ in the mare is naturally of the horse species; and did such germ merely receive the vivifying principle by the sexual in- tercourse, it would be indifferent to the future produce whether the father were a horse or an ass. "Some physiologists (and among them Sir E. Home) have supposed that the ovum or germ, previous to impregnation, is of no sex, but is so formed as to be equally fitted to become a male or female foetus, and that it is the process of impregnation that marks the sex, and produces both male and female generative organs. However this opinion may seem to be supported by facts, and although instances do occur that give reason to suppose that the male parent has con- siderable influence in determining the sex, yet others arise to prove the female to be equally concerned in this matter. It is true that some dogs, some stallions, and some bulls, are remarked for begetting a greater number of males than females ; while others are the parents of more females than males. In the Phil. Trans. 17S7, p. 344, mention is made of a gentleman who was the youngest of forty sons, all produced in succession, from three different wives, by one father, in Ireland. But it is, at the same time, equally notorious, that some bitches, let them breed by what dog they will, yet still have a plurality of one sex. The same occurs, in a much greater degree, among other domestic animals. Mr. Knight remarks on the equal aptitude in the female in determining the sex : " In several species of domesticated animals (I believe in all), particular " females arc found to produce a majority of their offspring of the same sex; " and I have proved repeatedly, that, by dividing a herd of thirty cows into " three equal parts, I could calculate with confidence upon a large majority " of females from one part, of males from another, and upon nearly an equal " number of males and females from the remainder. I frequently endeavoured " to change the habits by changing the male, but with success."— Phil. Trims. 1809, p. 397. In King's I. nuclei/ church are the effigies of seven successive daughters born to a man by his first wife, and of seven soils born to him by a second wife, in succession. 50 THE REPRODUCTIVE SYSTEM. be confined to a part of the progeny only, or is divided between the parents. This is sometimes observed when a breed is made between a pointer and setter, in which case it has not unfre- quently happened that a part of the litter has produced nearly thorough-bred pointers, while the remainder have proved well- bred setters. Breeding back, as it is popularly called among sportsmen, is not one of the least curious, nor one of the least important among the phenomena which attend the reproductive system. If it were not for the irregularities lately pointed out, which occasionally occur by mental influence, we might be led to conclude that a family character was originally imprinted on the generative organs, or that the ova or germs of the future race were formed after one common hereditary mould ; for it is often observed, not only among dogs, but among other domestic animals, and even in man also, that their progeny bear a greater resemblance to the grandam or grandfather than to their immediate parents. It is evident that this is more likely to happen where a common character has been preserved during successive generations, or, in turf language, where the blood has been kept -pure; which is nothing more than an established variety, being acted on in its successive generations by the owner, in the direction of the sexual intercourse, the selection of food, discipline of qualities, and regulation of habits. That we may not, however, attribute principles to nature which are, perhaps, much under the influence of art, it will be prudent to recollect, that, in a philosophical point of view, we have no such thing as a pure breed among any of our domestic animals. Our most boasted specimens are either altogether degenerates^ 9 A more close examination of the subject will shew not only that our most highly prized animals are degenerates, but that many of them are monstrosities. Degeneracy, among naturalists, is a departure from originality and a state of nature ; thus, philosophically, wild animals only can be considered as perfect. But man, to gratify his artificial wants, has cultivated forms and properties in them, which, however they may prove beneficial to himself, render the animals subjected to such alterations unfitted for the purposes they were originally THE REPRODUCTIVE SYSTEM. 51 or produced from congenital varieties ; the native and original types are mostly unknown to us. In tracing the natural history of the dog, we must feel convinced that what we call breeds are but varieties which have been generated by various causes, as climate, peculiarity in food, restraint, and domestication. Man, active in promoting his own benefit, has watched these gradual alterations, and has improved and extended them by aiding the causes that tend to their production, and by future care has per- petuated and made them permanently his own. Many of the varieties among dogs and other domestic animals destined for. What would become of some of our cultivated breeds of dogs, were they turned loose in a wild country? Could a pack of pugs hunt down the antelope ; nay, could they even subsist in a state of nature? The high-bred greyhound's speed and vision united would fail in the same circumstances; de- prived, as he would find himself by cultivation, of the means of following his prey through its various windings by scenting his course. The pointer might stand, and his partners might back him, until they became together converted into monuments of devotion to an artificial excellence which had converted them into a group of mummies : the pursuits of their cultivated talent would infallibly starve them. As promoters of the ease and comforts of mankind, every one yields the well-merited honours that are distributed among our enterprising cattle breed- ers ; but the philosopher, retired from the world, and the naturalist, con- templating his subject freed from extraneous bearings; they regard the boasted excellencies of our domestic animals in general as monstrosities. The majestic large breed of heavy cart horses, cultivated to their present stature by the luxuriant nature of the herbage in this and some other countries, would be ill calculated to save themselves from beasts of prey, by either flight or active resistance : their immense weight would sink them in loose soils, that their more agile originals wonld bound over with instinctive celerity ; and the scanty herbage in nature's wilds would ill suffice their multiplied wants. With the ox and sheep a constitutional obesity is encouraged, until the fat and mus- cular parts are lotally disproportioned to the bony mass that is to support them, which lessens, according to modern excellence, in an inverse proportion to its necessities; and, as though the degeneration was not sulh'ciently pursued, in the polled breeds those original marks of distinction and safety, the horns, also yield to the sacrifice. Even the finest edibles among our garden bulbs, as the carrot, parsnep, &c. &c. are monstrosities, enlarged at the expense of the stem and other parts ; and the disproportionate magnitudeof our fruit is attributable to the monstrosity of the pericarp. It is not attempted to argue that these are not actual advantages to mankind, nor to detract from the merit that lias intro- duced these acknowledged improvements ; if is merely suggested to show that misconception and mis-appropriation of terms often arise according as the sub- ject is viewed by the naturalist or the rural economist. D 52 THE REPRODUCTIVE SYSTEM. are the effect of monstrosity, or have arisen from some anomaly in the reproductive or breeding process. When these accidental varieties have exhibited a peculiar organization or form which could be applied to any useful or novel purpose, the objects have been reared and afterwards bred from; and when the singularity has been observed in more than one of the same birth, it has been easy to perpetuate it by breeding again from these congeners, and confining the future intercourse to them. To these accidental variations from general form and character among dogs we are to attribute our most diminutive breeds, our pugs, bull-dogs, wry-legged terriers, and some others10 : our general breeds are, however, rather the effect of slow cultivation than of sudden and extraordinary production. It has been before observed, that every variety or breed has a ten- dency to degenerate, or travel backwards to something like the ori- ginal standard : this tendency is greatest in the accidental varieties or breeds just hinted at, in which a few succeeding generations11 10 Among other domesticated animals, prominent instances present themselves of accidental variety. The solidungular breed of swine, with their undivided feet and the ancon or otter breed of sheep, described by Colonel Hum- phries, in Phil. Trans, for 1813, part i, may be noticed in proof. These sheep were derived from the accidental deformity of one American lamb, born with leSs most disproportionately short to the rest of his body, which deformity, added to great crookedness of the fore legs, rendered him unable either to run or to break fences. . With these qualities it was determined to attempt a breed of this kind; and, by confining the intercourse between him and his future offspring, it succeeded, and the ancon or otter breed is now established. The pure milk-white breeds which we witness now as permanent among ferrets, rabbits, mice, &c. originally sprang from one accidental vanet, of each Man himself is not exempt from this departure from estabhshed form ^ character^ as we witness in the Albino, who presents the same leucccth.op.c constitutional characters in the deficiency of colouring matter, a similar i^*™!™ pupU, and consequently the same intolerance of light, » the SLb.

THE REPRODUCTIVE SYSTEM. 53 is sufficient to destroy all appearances of variation from tlie original ; but in breeds more nearly approaching the original, as well as such as have been long established, it requires a much longer time wholly to degenerate them. The tendency to resume the original type is, however, inherent in all our domestic animals, and in none more than the dog ; and judicious efforts employed to counteract this property form a principal part of the art of suc- cessful breeding in rural economy. Notorious varieties or breeds are, therefore, the consequence of our attempts at the improvement of such races of dogs, or of any other domestic animals, as exhibited a constitutional tendency to a particular form or character, the properties of which are either known or expected to prove useful. Or they originate in the adoption of any accidental variety that may spring up in the way lately described. Or a breed may be established by any deter- minate form or quality, within certain limits, being previously fixed on ; after this individuals are selected, perhaps not exactly similar, but each of which having distinct points of resemblance to the desired form, conjointly, the full end may be gained in their own union and that of their affinities. In this way the most sur- prising alterations in the animal character have been, and still may be, brought about ; and forms almost ideal have been, and still may be, realized12. A breed or variety being adopted and established, its permanency must depend on the care bestowed not only in selecting proper individuals to propagate from, but also in the adoption of such other circumstances as tend to preserve the animals themselves in that state the nearest approaching to 12 Among the experienced fanciers of the small yellow and white spaniels, which much resemble those known by the name of the Marlborough breed, this is particularly exemplified. These elegant animals are very common among the Spilalfields weavers ; and to such a perfection have they brought the art of breeding them, that it is affirmed they can insure, almost to a cer- tainty, the requisite quantity of colour, the length of coat, its texture, and its disposition to cu:l or to remain straight. The Herefordshire ox can be bred to a white or a half white face ; and the horns of some breeds can be insured to an inch. The colour of the game cock is arbitrarily imposed by the handler and feeder ; and the experienced pigeon-fancier can breed to a feather. D 2 54 THE REPRODUCTIVE SYS'I EM. what has been established as the standard. These circumstances include choice of situation, proper food, due exercise, with judi- cious restraint and discipline. The aids we should lend to per- petuate a diminutive race would be, close confinement, artificial heat13, and sparing food. Were our attempts directed to the external covering, artificial warmth would render it thin and fine ; while, on the contrary, exposure would thicken and pro- bably lengthen it. If great size exists, and we wish to continue or increase it, we should allow but one or two young to remain in a fitter; we should not only feed the mother liberally, but it would be proper early to accustom the young to eat of animal food also : adding to all these, the free access of air, ample room, and opportunity for full exercise, But, above all, the perma- nency of a breed must depend on the judicious selection of in- dividuals as parents, which, having the specified and definite form in the greatest degree, are enabled in their progeny to perpetuate the same. This care, when long continued, of con- fining to particular races or breeds the means of continuing their species, constitutes what is termed purity of blood, Immense importance is attached to this purity of blood, or lineal descent, amongst the breeders of almost every kind of domestic animal^. The scientific sportsman acknowledges it, in its fullest degree, m .3 The French are said to give their diminutive breeds spirituous liquors When they are young, to stop their growth : if it has this effect, ,t ,s because Irtificial hen, and a Quickened circulation produce premature development of the frame, and thus promote an early pubertj. 14 The cart. taken by the Arabs in preserving the breeds of their horses m0st rtmarkabl;.

THE REPRODUCTIVE SYSTEM. 55 the genealogy of his clogs ; and experience teaches him that a certain degree of perfection, once gained, can only be continued by successive propagation from the blood or same stock. In our selection of parents for multiplying a breed a variety of circumstances should necessarily engage our attention ; as, whether we are continuing a race already established, im- proving a defective one, or altogether forming a new variety. In either case, but particularly in the two latter, one or two propagations are not sufficient to enable us to judge of the merits or demerits of the products : anomalies may occur, monstrosi- ties appear, or our dogs may breed back. It should likewise be always present to us, that, in despite of all our care, and in face of the most favourable opportunities for selection, still perfect speci- mens to propagate from are unattainable ; and as, therefore, we are necessarily to expect defects, it should be our care to well examine that we do not select our male and female parents with each the same faulty form or property; for, however perfect they may be in other respects, they are, in such a case, totally unfit to breed from together. We may, for instance, suppose an otherwise eligible pair of pointers, of the purest blood, but that each, from early and constant confinement, had contracted long, weak, spreading phalanges or toes, instead of a round, cat-like form of foot. By choosing a mate for each of these whose feet were unusually small, round, and firm, we might remedy this defect, and preserve their excellencies ; but it would be only propagating deformity to breed from them together. We can only expect to prove successful in rearing a superior race of any domestic animal, when we make our selection of parents with a careful reference to the merits and defects in each, by balancing the one against the other, and by thus combining their different properties. It is by inattention to these circumstances that so many persons, after giving immense prices for animals of particular stocks, have found themselves foiled in their attempts at rearing any thing beyond mediocrity, which animals under the judicious management of a Russell, a Coke, or an Ellman, among cattle, 56 THE REPRODUCTIVE SYSTEM. or an Orford, a Meynell, a Rivers, or a Topham, among dogs, would have produced unrivalled forms. It is no less to he understood, that it is not the form only that we can alter or bring into an hereditary line ; the aptitudes and qualities may also be cultivated and made to descend in succession equally with the external form. Temper, sagacity, and aptness to receive instruction, are all hereditary, and are all equally to be taken into the account by a breeder. Some breeds of pointers require little breaking, but the first time they come on game they exhibit the required properties with nearly the steadiness of an old dog. A common fault is often committed by theoretical and inexperienced breeders, which consists in cultivating a particular quality, or propagating a particular point of form ; while, at the same time, losing sight of the integrity of purpose, they deteriorate the aggregate. In this way, fox-hounds may be bred to run nearly as fast as greyhounds, but it is at the expense of their scent, their hardihood, and, I suspect, of their sagacity also. For it cannot be too strongly inculcated on the mind of every breeder, as an established law in the animal economy, that an extraordinary de- gree of excellence existing in any set of organs, whether it be natural or acquired, is almost invariably accompanied with a pri- vation of the usual quantity of it in some other is. This law is fully exemplified in those animals where breeding is carried to its greatest refinement; or, in other words, where cultiva- tion in qualities or form, or both, weakens or destroys the in- stinctive habits and original structure to such a degree as to make the subjects of it inferior in their reproductive processes, both as breeders and rearers of progeny; and which appears to extend throughout all our very high bred animals : among the feathered race it is peculiarly remarkable.

Breeding Li-aud-In. — Among tlie practical and systematic breeders of all domestic animals, and among none more than those sportsmen who devote themselves to the improvement of the dog, a great diversity of opinion has always existed on the subject of consanguineous breeding; or of that between near re- lations, characterised by the term In-and-in. The conflicting authorities on the subject are numerous, and the testimonies con- tradictory ; and it is more than probable that they will remain so, until a long course of experiment is undertaken by a body or society of scientific and observant breeders on various domestic animals, for the express purpose of arriving at the truth in this particular. A few solitary or isolated facts can do little to set the subject at rest : theory can only assist by philosophically di- recting the inquiry aright : truth should be the ultimate object of every pursuit, and, from whatever source it is obtained, it should be embraced. I profess to have had little experience my- self as a practical breeder, but I have endeavoured to profit by the experience of others. I am by no means wedded to the in- and-in system of breeding; and when I hear grave authorities stating facts (the only sure guides to truth) against it, I am dis- posed to waver; but renewed examination produces counter statements, and I retrace my steps and become, as formerly, a defender (but, I own, not so zealous one) of consanguineous breeding. I will, however, endeavour to state the pro's and con's fairly, and then leave the matter, where it should be left, with the experimentalist. The first argument that presents itself in favour of multiplica- tion from near relationship is, that the early human and brute races must of necessity have been produced from the nearest affinities ; and it is unreasonable to suppose that nature would have set out on a principle tending to the immediate deteriora- tion of her works. This, however, has been called the mere argu- ment of necessity, and is said to apply only to the precise period 58 THE REPRODUCTIVE SYSTEM. when there was no other connexion possible. I admit that tliis is an argument of necessity, viewed with reference only to pri- mitive times; but it stands otherwise, when we reflect that, tor ages after, consanguineous marriages were consummated among nations of refinement, and to this day, among savage tribes par- ticularly, their reigning families and chiefs confine themselves to marriage among lineal kindred16; and yet in neither instance has any degeneration been observed. From a parity of reasoning, as we know that an insuperable bar has been placed against propagation among the several genera, by an instinctive, aver- sion, that the specific forms might not be lost in hybridous productions ; so it does not appear to be straining analogy too much to suppose that, had ill effects followed from consan- guineous intercourse, something like this instinctive aversion would be manifested here also". Neither does it appear, a priori, easy to substantiate either moral or physiological reasons why is The Egyptians are said to have allowed of the marriages of brothers to sisters. The Athenians admitted the betrothing of brothers and sisters of the half blood, if related by the father's side. The marriage of Abraham with his sister assures us that it was practised among the Chaldeans; and it may be re- marked, that, when this island was conquered by Ca>sar, a peculiar system of cohabitation prevailed.-Uxores habent deni duodenique inter se communes, et maxime fratres cum fratribus, parentesque cum liberis; sed si qui sunt ex his nati, eorum habentur liberi, quo primum vurgo quasque deducta est.— Paley'sNat. Hist. " It may be argued, that such aversion is manifested in the political restric- tions relative to consanguineous marriages among enlightened nations. That such prohibitions were necessary from moral and political necessity is evident; for, by extending the social compact to marriages without the family pale, knowledge and the arts were extended, improved, and became a common property ; wealth was diffused, communities were enlarged, and social inte- rests joined those who before were in opposition to each other ; and, above all, the demoralizing and depopulating effects of an early departure from chastity, which unreserved family communication led to, was prevented. It is however, clear, from history and from philosophical investigation, that such aversion is neither instinctive nor necessary, but an acquired regulation of passion, implanted by education, and made general by refinement. Sir W. C_N observes that, according to Varro, this aversion has really occurred even in animals — Equus matrem ut saliret adduci non posset, Dv Re Rmlica, lib. ■ ii, e. 5; but the ingenious Baronet candidly acknowledges that subsequent experience has not justified the assertion. THE REPRODUCTIVE SYSTEM. 59 breeding among lineal kindred should of necessity prove de- teriorating to the future progeny, when no family departure from the original type is apparent. The same organization, the same constitutional sympathies, the same aptitudes, when not defective, would tend, under union, to produce a perfect simili- tude : but facts are infinitely more to our purpose than the most specious arguments. We are assured, that the Arab horses of high blood are usually bred in-and-in; and we know that no people in existence are equally observant of the purity of lineal descent among these animals as they are ; and as these horses have maintained their high character for ages, it forms a strong presumption in favour of this system. Mr. Bakewell, whose name will ever rank high as a breeder of cattle, reared his valuable stock wholly from consanguinity: in fact, his important improvements were all founded on this intercourse among kindred, or their affinities. Mr. Meynell, who was no less celebrated as an experimentalist in the breeding of sporting dogs, propagated the whole of his celebrated fox hounds in this manner. I have already stated, that numerous and powerful opponents exist to the system of in-and-in breeding, whose opinions ought to have their due influence when considering the question18. Sir John Sebright, who has been long known as a practical breeder and scientific experimentalist, has given us his opinions on the sub- ject, in a Letter on The Art of Improving the Breeds of Do- mestic Animals ; and as great importance is justly attributed to his opinions, as there detailed, I shall, in candour, quote so much as is necessary to shew the drift of his arguments. He says, "If " a breed cannot be improved, or even continued in the degree "■ of perfection at which it has already arrived, but by breeding " from individuals, so selected as to correct each others defects, 18 The principal arguments, in my own mind, against tins mode of increase are that hereditary diseases, which in some breeds are considerable, arc, by ibis means, perpetuated and probably increased; and also, that when breeding by relationship is a settled practice, the accidental defects are too upt to be passed over unobserved. 00 THE REPRODUCTIVE SYSTEM. " and by a judicious combination of their different properties (a " position that I believe will not be denied), it follows that " animals must degenerate by being long bred from the same " family, without the intermixture of any other blood, or from " being what is technically called bred in-and-in." Against the contrary opinion, as held by Bakewell, the ingenious Baronet thus reasons : — " No one can deny the ability of Mr. Bakewell " in the art of which he may fairly be said to have been the " inventor ; but the mystery with which he is well known to " have carried on every part of his business, and the various " means which he employed to mislead the public, induce me " not to give that weight to his assertions, which I should do to " his real opinion, could it have been ascertained." To Mr. Meynell's opinion of the same tendency, he replies — " Mr. Mey- " nell's fox-hounds are quoted as an instance of the success of "this practice (i.e. the in-and-in ) ; but, on speaking to that " gentleman upon the subject, I found that he did not attach the meaning that 1 do to the term in-and-in. He said, that he " frequently bred from the father and the daughter, and the " mother and the son. This is not what I consider as breeding " in-and-in ; for the daughter is only half of the same blood as " the father, and will probably partake, in a great degree, of " the properties of the mother." Sir J. S. also, in another part of his letter, states some im- portant facts on the matter in these words : ~" I have tried « many experiments by breeding in-and-in upon dogs, fowls, " and pigeons : the dogs became, from strong spaniels, weak " and diminutive lap-dogs ; the fowls became long in the legs, " small in the body, and bad breeders." Sir W. C n, in his Treatise on Greyhounds, is also, in some degree, unfavourable to breeding a-kin. He says, " II " continued for some litters, a manifest inferiority of size, and a " deficiency of bone, will soon be visible, as well as a want ol " courage and bottom; though the beauty of the form, with the « exception of the size, may not be diminished." THE REPRODUCTIVE SYSTEM. Ol Buffon argues on the same side:—" Ce qu'il y a de singulier, " c'est qu'il semble que le modele du beau et du bon soit dis- " perse par toute la terre, et que dans chaque climat il n'en reside " qu'une portion qui degenere toujours, a moins qu'on ne la « reunisse avec une autre portion prise au loin ; en sort que pour " avoir de bon grain, de belles fleurs, &c. &c. il faut en en- '« changer les grains et de ne jamais semer dans le meme terrein « qui les a produits ; et de meme, pour avoir de beaux chevaux, « de bons chiens, &c. &c. il faut donner aux femelles du pays des "males etrangers, et reciproquement aux males du pays des " femelles etrangeres ; sans cela les grains, les fleurs, les ani- " maux degenerent, ou plutot prennent uni si fort teiuture du " climat, que la matiere domine sur la forme, et semble l'aba- " tardir, I'empreinte reste, mais defiguree par tous les traits, qui " ne lui sont pas essentiels. En melant au contraire les races, et «* surtout en les renouvelant toujours par les races etrangeres, la " forme semble se perfectionner, et la nature se relever et donner " tout ce qu'elle produit de meilleur." Buffon Hist. Nat. torn, iv, p. 216.— Mr. Beckford, in his Thoughts on Hunting, appears equally averse to consanguineous canine breeding. " A very fa- « mous sportsman has told me, that he frequently breeds from " brothers and sisters. As I should be very unwilling to urge " any thing in opposition to such authority, you had better try " it ; and if it succeeds in hounds, it is more, I believe, than it " usually does in other animals." It remains to add, that many practical breeders of inferior note are averse to propagating in succession from near relationship by blood, as brother and sister, father and daughter, &c. &c. ; but many allow even the benefit of relationship in a more remote degree. This is particularly the case with some rearers of game fowls, who are favourable to breeding from the third remove, which they call a nick. From all which discrepancy of opinion may be gained, that the subject is at present somewhat pro- blematical; and, that the opposition to it, if not altogether un- founded, lias, nevertheless, not yet received such an accumulation 02 THE REPRODUCTIVE SYSTEM. of striking and incontrovertible facts as to force conviction. One thing it is but just to state, which is, that breeding in-and-in among dogs, which is the point more immediately connected with our present inquiry, seems to have more opponents than it has in the multiplication of any other domestic race of animals. Whe- ther it be, that dogs, from their habits of close intimacy with us, aftbrd more opportunities of close observation ; or whether there be really an inherent aptitude in them unfavourable to propaga- tion from near affinities, is not agreed on generally; but the prejudice deserves to be fully canvassed by a series of experi- ments and observations, having for their object the truth, and that only. THE REARING OF YOUNG DOGS. To procure the whelping of dogs in the spring is undoubtedly desirable in kennels where many dogs are reared ; and in such it is usual to encourage the season of heat in the females by liberal feeding, &c, so that the young thus early produced may benefit by the genial warmth of the summer, and expand their limbs by exercise in the open air more freely. The number of young that are brought forth at a birth varies from one to twelve : instances have occurred where sixteen have been whelped, and I once re- moved the same number from a dead setter : five, six, and seven, are common numbers^. How many it is proper for the mother to rear, must depend on circumstances : one that is very strong and healthy may, with full feeding, bring up five : but when the breed is valuable, and great size and strength are required, four, or even three, are more proper : among the delicate breeds no more should ever be allowed. If a foster mother is procured for the supernumerary pups, she should, if possible, be of the same breed with themselves ; for from the experience I have had in this particular, I am strongly inclined to believe that the qualities ■9 Albertus relates his knowledge of a mastiff bitch, which littered the vast number of fifty young ones at three consecutive parturitions; viz., nineteen at the first, eighteen at the second, and thirteen at the last. REARING OF YOUNG DOCS. 63 of a foster mother are, in some degree, transferred with the milk; and when the breeds are distinct, this must be very pre- judicial. I am also borne out in this opinion by the testimony of other observant sportsmen2<>. Constitutional diseases may be likewise gained by this means*. At times, some difficulty is experienced in getting a foster parent to receive strange young : in which case it is usual to sprinkle them with the milk of the bitch they are to be put to : but when even this will not avail, the removal of her own young will commonly excite the feelings of maternity towards the stranger : the former plan is, however, commonly sufficient, acting as it does on a similar principle with that by which shepherds succeed, who when a ewe dies, take her lamb, and, having found a ewe with a dead one, the dead lamb's skin is stripped off by them, and sewed around the living lamb, who is then received by the foster parent as her own. Most animal instincts connected with the reproductive system are conducted by means of smelling. Puppies are bom blind, and remain so for many days ; their ears are also impervious. Eyesight and hearing would have been useless to animals so indigent, and which, in a state of nature, were intended to remain buried the first weeks of their existence in holes and dark caverns. These organs only deve- • lope themselves when their owners begin to be sensible of their wants : the lids unclose by degrees, and then exhibit a mem- branaceous covering, or rather a thickened state of the conjunctive tunic; but which gradually becoming absorbed, presents ulti- mo The learned author of A Treatise on Greyhounds introduces some quo- tations to shew that this effect had not escaped the attention of the antients. Columella, lib. vii, c.12, has the following remarks on it:— "Nec nunquam eos "quorum generosam volumus indolem conservare, patiemur alienee mitncis "uberibuseducari, quoniam semper lac et spiritus maternus longe magis m- « genii atque incrementa corporis augent." Similar observations occur in Xc- nophon. de Venal. 987; Oppian. Venal, i, Wi-Cynosophium &c > I was acquainted with a very fine child with diseased eyelids, who was the only one thus affected out of a large family; she was likewise the only one put out to nurse. The woman who suckled her had a large family also, and most of her children have the same affection; and I have traced diseases m dogs, and habits also, to the source of foster parentage. 64 REARING OF YOUNG DOGS. mately a perfect eye. At this early age, the whole skin presents a beautiful pink tinge, which disappears by degrees, and gives place to a clear white in most parts of the body ; while the rctu- mucosum of such parts as are intended to exhibit a dark hue, as the roof of the mouth, paws, nose, &c, at the same time assumes its intended colour. The upper milk or temporary teeth, both cutting and grinding, appear first, and are tolerably complete at a month old ; the others appear later, by which arrangement the teats of the mother do not suffer : the milk teeth give place to the permanent set at six or seven months. The testes do not descend into the scrotum till the third, fourth, or fifth week, but they may be felt a week previously within the abdomen, on each side of the penis. Dogs are often born with supernumerary claws, among sportsmen called dew claws : some of these have a corresponding metacarpal or metatarsal bone, others are appendant only to the integuments. In either case they should be taken off early.— See Operations. n. When many young of a litter are preserved, they should be early accustomed to lap : milk which has been boiled and slightly sweetened is proper ; when given raw it is apt to purge, and sweetening it makes it more nearly resemble the mother's milk. Meat, also, cut fine may be early given, as it will materially save the mother, and benefit the progeny also: clean litter, free access of air, and room for exercise, are essentials to their well doing. Young dogs should be early accustomed to restraint, with a chain and collar ; otherwise, when they are accidentally tied up, it is apt to occasion great alarm: I have seen fits follow this. Confinement, however, under any circumstance, should be only occasional, and never long continued : thousands are ren- dered weak, ricketty, and have their feet spread out into thin narrow phalanges, by close and early confinement. Young dogs are liable to several diseases that are peculiar to this stage of their existence. One of the most fatal of these is of a tabid nature, and appears principally confined to some breeds, particularly to terriers, pugs, the smaller kinds of spaniels, and REARING OP YOUNG DOGS. 65 others of the diminutive races ; and more especially to such as live luxuriously, and are closely confined. Among these, certain individuals at each littering present young, either already dis- eased, or with such a tendency to it, that the complaint alluded to soon makes its appearance, and with greater certainty when they have to combat with bad air, confined situation, and want of sufficient nutriment. — See Diseases of Glands, Class V. Worms are very common in young dogs, perhaps few are without them ; whenever, therefore, puppies have fits, irregular bowels, violent and unnatural appetite, and a general unhealthy appearance, worms may be suspected as the cause. — Rickets also are very injurious to them sometimes, particularly among the breeds that are closely confined, as in cities and large manu- facturing towns. See Diseases of Bones, Class VI. Young dogs are also liable to a peculiar spasmodic affection of the bowels. I have seen it epidemic among them. See Spasmodic Colic, Class II. The age of dogs. — These animals do not, like horses and cattle, present any exact criterion of their age ; nevertheless, attention to the following appearances will assist us in deter- mining the matter. At about four years, the front teeth lose their points, and each of them presents a flattened surface, which increases as the age advances ; they likewise lose their white- ness. In dogs fed much on bones, and in those who "fetch and carry? these teeth suffer very much, and are sometimes broken out, while the dog is yet young. The holders, or tusks, are also blunted by the same causes. At seven or eight, the hair about the eyes becomes slightly grey. Gradually, likewise, a greyish tint extends over the face ; but it is not till ten, eleven, or twelve years, that the eyes lose their lustre : when become dim, general decay proceeds rapidly, though the life of some dogs is extended to fifteen, sixteen, or seventeen years ; and I have seen a mother and son vigorous at twenty and twenty-one years old. Although such instances as the latter must be considered as rare, jet even these have been exceeded, if I might depend on my au- GG GENERAL TREATMENT. thority; for I once saw a small French clog, which I was assured had reached his twenty-fourth year, and which, at the time I saw him, was still vigorous and lively. I am not aware that much difference exists between the various breeds, as to the age they ar- rive at : spaniels, however, I have observed are usually long lived ; while terriers, on the contrary, I have seldom observed very old. The usual life of the dog may be considered as ranging between twelve aud fifteen years : domestication has tended, in some de- gree, to curtail the period, but not so much as might be expected2, considering the powerful operation of artificial habits. THE GENERAL TREATMENT OF DOGS AS PREVENTIVE OF DISEASE. The prevention of disease, it is evident, is an important con- sideration ; and, as such, it may with propriety precede the cure. To guard against the loss of health, we must carefully regulate the essential habits of life of the animals we domesticate. Thus, with our dogs, we attend to their feeding, housing, cleanliness, and exercise. We must also examine their condition, on which both their ordinary health, and their capability for such services as we require of them, will much depend. The feeding of dogs.— This is necessarily an object of im- portance, not only as regards the wants of the animal, but also as respects the different quantities and qualities proper under dif- ferent circumstances. A great error is committed when we feed our dogs on one scale: such as giving the dog which has slept through the day, the same quantity as is set before the pointer that has been hunting incessantly four or five hours. In qua- 2 Buffon calculates the length of life in the dog from the time of his growth. " La duree de la vie est dans le chicn, comme dans les autres auimaux, pro- " portionelle au temps de I'accroissement ; il est environ deux ans a croitre, ils " vit aussi sept fois deux ans."— Buffoti, Hist. Nat., torn, v, 223. /Elian considers fourteen years as the natural period of life in dogs.— JElian, De Nat. Animal., lib. iv, c. 41. Some of the ancients have stated that a difference exists in the duration of life between the sexes, but experience justifies no such distinction. Arnanus !) animal food affords most nutriment, so, when the bodily exer- tions are great, as in sporting dogs, then flesh is the best food. On the contrary, when bulk without much nutriment is required, as for such as are much confined and do little, then vegetable matter is best adapted to their wants. This subject appears to be one of very general iuterest ; for no questions have been more frequently asked the author of these pages, than- -What kind of food is the best for dogs, and what quantity of it ? It is difficult to prescribe generally a precise quantity— some dogs require even naturally more than others ; and, for the same reasons, it is not easy to give general directions with regard to the quality and kind also. If, however, the rationale of nutrition be at- tended to, and the above principles kept in mind, the owners will find no difficulty in deciding when one or the other kind is proper, or when a mixture of both is to be preferred. Many opinions prevail on the subject of horse-flesh as food for dogs ; its qualities being as strenuously supported by some, as they are condemned by others. The proper mode of con- sidering the matter is to regard it as a strong and actively nutritious food, very fit for dogs who undergo great exercise ; to such it never proves hurtful: but where it is given to those who have little exercise, it proves too nutritious, and is apt to pro- duce a foul stinking coat and itching skin. Much diversity of opinion prevails also as to whether it is better to be given raw or dressed. In a state of nature, it is evident that dogs live on raw meat, and there is no doubt that this best fits them for very active exercise, and endues them with the most vigour and du- rability. Raw flesh of every kind appears particularly to in- crease the courage and ferocity ; and where these qualities are requisite, this mode of feeding will undoubtedly tend to add to them: such food may therefore be considered as proper for sporting dogs, as greyhounds, foxhounds, and harriers, in the height of the season of their employ : for pointers, setters, and spaniels, in very hard and constant work, it is equally good ; but with moderate work, I have found mixed food pre- e 2 70 FEEDING OF DOGS. ferable, obedience and sagacity being here more wanted than ferocity. When, therefore, raw meat, as horse-flesh, can be pro- cured sweet and fresh, it not only increases the animal ardour, but it will go the farthest of any in point of economy, by nou- rishing- most. When it is at all putrid, dressing considerably restores it. Carrots, parsneps, cabbages, and, indeed, all vegetable matter, will feed dogs sufficiently well for the purposes of existence; and if either milk or good pot-liquor be added, they will form a nutritious diet. It is, however, prudent here to introduce one very necessary caution, which is,— that the broth or liquor in which salted meat has been boiled should never be used for this purpose. Most dogs who have been confined on ship board during a long voyage contract an obstinate species of mange, wholly owing to their being fed on salt pot-liquor. This is not sufficiently attended to among sportsmen ; and their servants are very apt to give the liquor in which salt pork and bacon have been boiled, with other brine, to the great injury of the animals. Greaves, or the refuse of the matter from which tallow has been pressed, is with many persons a favourite food, because it is a convenient one ; and, when mixed with a sufficient quantity of vegetable matter, it makes a hearty meal for large dogs, or such as live without doors, and are subjected to much exercise. I should, however, never make use of greaves myself, when any of the before-mentioned articles could be procured. The inhabi- tants of cities and great towns often find it extremely incon- venient to find food for large dogs, particularly when there are many to feed. The following plan is peculiarly adapted for such situations ; and, by this means a wholesome, nutritious, and cheap food may be conveniently obtained. It consnsts of the tripe or paunches of sheep, which, being thoroughly cleaned, are to be boiled half an hour, or forty minutes, in a moderate quan- tity of water. When taken from the water, they should be hung up to cool, and the boiling liquor they came out of should be poured on bread raspings ; those of French bread are the best. FEEDING OF DOGS. 71 The quantity of raspings should be so regulated, that, when soaked and cold, the mess may be of the consistence of an ordi- diuary pudding before boiling. The paunches being also cold, but not before, should be cut into fine pieces, and mixed with the soaked raspings : when raspings cannot be procured, meal or biscuit may be substituted. The mixture, it is evident, may be made to contain more or less animal matter, by increasing or lessening the proportion of paunch, or other kinds of meat may be substituted ; but the author is disposed to think that tripe is at once nutritions and innocent, and tends little to make' a dog foul and gross. When likewise it is intended or wished to make the mixture more enticing, the offal or intestines of chickens and other fowl may be obtained from the poulterers, and boiled with the tripe. Of all substances in general use, except horse-flesh, the entrails of chickens is that most eagerly sought after by dogs ; and it is one which fattens them faster than any other. For the convenience of persons resident in London, it should be noticed, that the venders of ready dressed sheep heads sell the trimmings as clogs' food, and they form an excellent one. Sportsmen in the country who are averse to flesh-feeding, or cannot always procure it, use various articles for the purpose : it is likewise very often, in retired situations, a difficult matter to find proper substances for this purpose. In some kennels a mixture of meal and milk is used, aud dogs will thrive on it during the season they do not hunt ; but when they are strongly exercised, and hunt several days in the week, this food is hardly sufficiently nutritious. All the meals of wheat, barley, oats, and rye, are used for dog-food ; but it is no difficult matter at once to decide, that wheat meal, when it can be procured, is to be pre- ferred ; for it is much less likely to produce mange and a heated skin than the others. Biscuits are in very common use: the damaged sea-biscuit is often employed ; but of late, Smith's dog bread has taken the lead with many good sportsmen, and is good, being known to be a compound of the different meals. 72 FEEDING OF DOGS. Barleymeal and oatmeal are very commonly used, and either is sufficiently nutritious when mixed with milk or broth ; but they have certainly some tendency to produce a red itclnng skin when constantly used ; for which reason a portion of potatoes should be mixed with them. Potatoes, even without meal, will be found to form a good food for dogs which are not wanted for very active exertion : they are cooling, and, when mixed with milk or butter- milk, are sufficiently nutritious for all common purposes, and form in this way an economical and wholesome food: if they are not relished alone, a small proportion of greaves, or other fatty matter, may be added, which will render them palatable. When circumstances render it absolutely necessary to feed principally on either barley or oat meal, the heating effects may be also greatly obviated by mixing it with buttermilk. In all cases likewise of eruptive affection, as mange, canker, &c, but- termilk will be found to possess something of a curative as well as preventive quality. In the feeding of favourites much error is frequently com- mitted ; for, their tastes being consulted, they are too apt to be wholly fed on flesh, and this in great quantities too. In such cases, although the evil is acknowledged, yet it is alleged that the animals will not eat any other food ; it is, however, always in the power of those who feed them, to bring them to live on vegetables entirely even, if it be desired ; but it requires, in some cases, considerable determination and perseverance. If the usual quan- tity of meat a dog eats be minced extremely fine, and a small portion of mashed potatoes be mixed with it, it will not be possible for him to separate the animal from the vegetable por- tion : if he refuses to eat the mixture, let it remain until hunger obliges him to do it. At each meal, a very small additional quantity of potatoes may be added ; and this practice, if persisted in, will bring him at last to live almost wholly on potatoes, or any other vegetable that may be selected . In a medical point of view, a vegetable diet is often very important. In many cases a com- FEEDING OF DOGS. 7* plete change of food forms the very best alterative; and, in others, it is a most excellent auxiliary to the curative treatment which is to be adopted. The cases that require a change from an animal to a vegetable diet are frequent: all eruptive diseases; all fat and plethoric dogs ; all coughs, dependent on congestion or repletion ; and various other inflammatory tendencies, render sucli change essentially necessary to the health of the dog. At what periods dogs ought to be fed, is frequently likewise a matter of consideration and difference of opinion ; but is most likely to be settled aright, by considering it on the principles already touched on. In a state of nature, even a daily meal among dogs must be very precarious ; for, in some situations, vegetable food cannot be obtained, and then the hunting down of other animals, or the meeting with the offal or refuse of what may have been hunted by others, must be the principal support. For this reason, Nature has kindly and wisely fitted a dog with a stomach that digests his food, particularly of the animal kind, very slowly ; so that a full meal of flesh is not digested in less than twenty-four hours. Those, therefore, who feed their dogs on animal matter never need to do it more than once a day ; nor do dogs require to be fed oftener if meal be given, when the quantity is sufficient. But it must be remembered that, under a life of confinement and art, where all the functions are weakened, as they must of necessity be in those dogs who are petted and indulged, it is better to feed them in smaller quantities twice a day. If fed once only, they become heavy and sleepy, and lose much of their vivacity. This may elicit an observation, that hard-worked dogs, as soon as fed, should be shut up, to encou- rage sleep. Digestion goes on better sleeping than waking; and more nutriment is obtained from the food in this way than when an animal is suffered to run about after eating. It may be also not improper to notice the unnecessary fear that many persons encourage relative to the giving of bones to dogs. Except from those of fish, or the legs and wings of poultry, which break into splinters, and may choak, I never 74 HdUSING OF DOtiH. remember having seen a dog injured by a bone ; but I have great reason to think that the stomachs of these animals would be often benefitted by the action of the bones : and also, that although the teeth are thought to be broken by them (and now and then, though but seldom, they may be), yet that the evil is more than counter- balanced by the mechanical action of the bones cleaning away the tartar, that otherwise accumulates around them. ]STo fear need be entertained of their occasioning obstruction ; the power of their gastric juices is equal to the total solution of the largest bones they can take down. 1 have seen a pointer of my own swallow the shank bone of a leg of mutton, which he was unable, from its size and strength, to break. I am of opinion that bones are a healthy addition to their food, and certainly, from their soluble cpialities, they are very nutritive. The stomach of the dog is as complete a digester of bones as the iron screwed pot ap- paratus of Count Rumford. THE HOUSING OF DOGS. This subject will occupy but little of my time, as I would hope there are not many persons who would be inhuman enough to turn an unoffending and faithful animal out without shelter during the cold and clamp of our nights4. Too many, however, err on the other hand, by placing their dogs in close coufined 4 In charity, I would believe, that when persons turn their dog out to sleep in the open air, they conclude him to be naturally a nocturnal animal, and that therefore such exposure is natural to him; but they are totally in error : and even had he been so in his aboriginal state, yet artificial habits and close domestication have so altered his nature, as to render him unfitted to cope with cold and moisture without pain and danger. The dog, however, really is not by nature a nocturnal animal, like the fox, whose predacious habits in search of fowls when at roost make night the especial season of his prowtings; and to which end nature has furnished him with a structural peculiarity in his organs of vision, totally different to that of the dog. The eye of the fox presents a pupil like that of the cat, likewise a nocturnal animal, whose contractions are not. circular, like those of the dog, or our own, but are linear, and capable of ex- treme dilatation and contraction. The dog having no such apparatus, was evidently intended to sleep during the night; and as in a state of nature he could furnish himself with a cavern, surely his master ought to supply him with some shelter: if with a kennel, let the opening incline to one side. W ASHING OF DOGS. 75 boxes or houses, without sufficient ventilation. A wicker basket is the best covering for most pet dogs, except Italian greyhounds and the naked Barbary dog, which may be further protected by a wooden house, or by a coverlet. Dogs sleeping without doors should have the use of a kennel well closed from rain and wind ; but, of course, open in front, provided such front is not opposed to driving rain, snow, &c. I would not even mention such minute matters, but that I know some well-meaning persons err from want of thought more than from want of humanity. The sportsman may assure himself, that the comfort of a sheltered and even soft and warm bed of straw, are as necessary, not only to the comfort but to the health also of his dog on his return from the fatigues of the chase, as the feather-bed and its coverings are to himself. The same stiffness, the same rheumatic pains, and inca- pacity of ready motion, await the dog as his master, if these pro- tections are not enjoyed by both. The kennels of our best hunting establishments are usually excellently adapted to give sufficient warmth with sufficient ventilation ; but it is of much importance, where hounds sleep on benches, that no direct draught of air be allowed to drive over them. WASHING OF DOGS. There are few sources more productive of disease to dogs than a wanting of general cleanliness in the air they breathe, and in the state of all those matters they are in communication with, as their beds, &c, and particularly in the state of their hides. Doo-s confined together in a close unventilated situation beget coughs, which often end in permanent asthma : if young, they be- come tabid; if adults, mangy or dropsical. The acrid fumes from their own bodies, when in close confinement, and more par- ticularly from their urine, stimulate the eyes, and produce diseased eyelids. It is also assistant to health, that confined dogs should have their hides rubbed every day with a hair cloth, or a w isp of straw : this dislodges the furfuraceous matter of the skin, 7() WASHING OF DOGS. and prevents its adhesion, which forms the first step to mange : it also assists general circulation, and stands in the stead ot exercise. This practice of rubbing would prove an excellent substitute tor washing in many cases, particularly where water proves injurious, which it sometimes does to delicate dogs. Washing of dogs is, under some circumstances, a very ne- cessary practice, and, when judiciously managed, is salutary also : but, when otherwise, it is productive of more mischief than persons are aware of. There is not a more fertile source of disease to dogs, than suffering their coats to remain wet after washing or bathing. In the first place, it subjects those who are unused to it to colds, distemper, inflammations, or asthma ; and in those to whom the practice is common, it is scarcely less pernicious ; for, though it may not occasion immediate disease, it nevertheless, in the end, frequently produces canker or mange. It may be observed, as a proof of this, that dogs who often go into the water are seldom without some affection of this kind. Canker, particularly, is almost confined to dogs who swim much, or who are washed often, without being properly dried after- wards : it should, therefore, be most attentively observed, when clogs are washed, that they are also carefully dried after it. Very small dogs, for this purpose, may be wrapped up in a blanket : large dogs, after being well rubbed, may be permitted to run into a stable among clean straw, which is a very excellent means of drying them, and, from its warmth, a very safe one. It should also be remembered, that, in ascertaining the proper warmth of the water for the washing of dogs, the heat, which appears trifling to the hand of a servant always used to dabbling in suds, will scald an animal unused to any thing but cold water. Washing should not be repeated oftener than once a week, even with the best care ; for it certainly promotes mange and canker. Rub- bing the skin with a flannel and dry bran is better. In slight rednesses of the skin, washing with common gin will often remove them. In similar cases, yellow soap well rubbed in, and then EXERCISE. 77 completely washed off, is also a good practice. But, however hurtful a too frequent system of water washing may be to healthy dogs, to diseased ones both hot and cold bathing are of the greatest service. — See Bathing, Class XIV. EXERCISE. The want of due exercise is the cause of nearly one half of the diseases of dogs ; and the ill effects of this deprivation are very often heightened by inordinate feeding also. It should be re- membered, that a dog is an animal of prey, destined, in a state of nature, to hunt for his food, and to sacrifice to his appetite lesser and weaker animals, whose exertions to escape must keep him in a continual habit of most active exercise. Wild dogs, therefore, probably do not get a regular and full meal twice in a week : how great, therefore, must be the difference, when they are either shut up in a warm room twenty-two out of twenty- four hours; or are, perhaps, fastened by the necks for many months together, without any other exercise than what the length of their chain allows them ! In such cases, if they have plenty of air, and are moderately fed, the want of exercise shews itself by mange or canker: if the repletion does not escape by this outlet, then the effects become apparent by an enormous increase of fat, which usually ends in asthma and dropsy. Nothing affords a stronger conviction of the necessity of exercise to animals than their natural love of play, which was given as a principal means of preserving health. In cities and great towns, it is a very excellent plan to teach puppies to play with a ball ; by which means they will exercise themselves very well in wet weather, or when they cannot be taken out ; and, when early taught it, will continue through life attached to the exertion : such as will not amuse themselves in this way, may yet all be taught to fetch and carry. A very mistaken opinion prevails, that, because a dog is turned into a yard or court an hour, or half an hour, that he exercises himself ; on the contrary, in general he regards this as a punishment, and sits shivering at 78 EXERCISE. the door the whole time. Dogs are more disposed to take exercise in company than alone : emulation induces them to run and frolic with each other ; it is prudent, therefore, to allow every favourite a companion. For sporting dogs, constant ex- ercise is also essentially necessary : when taken up for the season, if they are close kennelled, it is very common, when they are again wanted, to find them fat, out of wind, and easily fatigued ; for not only is the habit of exertion lost, but the muscles of the body have actually become lessened and weak- ened by the inactivity. Exercise improves the wind, by taking up the surrounding fat from the heart and chest ; thus allowing the lungs to expand more freely. Fits are a very common con- sequence of confinement without regular exercise ; and it is very usual for a dog, particularly a sporting one, which has been closely and long shut up, on gaining his liberty, to experience a violent fit : the same also occurs to clogs after long voyages. Exercise should, therefore, be allowed to every dog; and as this should be done in proportion to his other habits, to lay down any general rule on this head is nearly impossible : for such as are very fat, it should not be violent, but it should be long continued ; when too violent, it is apt to produce epilepsy or asthma. Sporting dogs require gallops, to fit them for their work, and to give them wind ; and, for this purpose, they should be taught to follow a horse. Lesser dogs, and all who are at other times confined, require at least two hours' exercise every day. Whenever circumstances absolutely preclude exercise, the only preventive to the evils threatened by the deprivation, is a lessening of their food, and that it be principally composed of vegetables : alterative medicines, as laxatives and emetics, should also be administered.

The term condition, as applied to dogs, is correspondent with the same term as used among horses ; and is intended to cha- racterise a healthy external appearance, united with a capability. CONDITION. 7y from full wind and perfect vigour, to go through all the exer- cises required of them. It is, therefore, evident, that condition is of material consequence to sportsmen : indeed, it is of in- finitely more importance than is generally imagined. What would be thought of the sporting character, who should enter his horse for racing without any previous training? And how much chance would he he presumed to have, even « to save his distance," without this precaution? Is it not equally reasonable to suppose that pointers, setters, spaniels, and, more than all, oreyhounds, require training ; or, in other words, to be m full condition also? It is notorious, that pointers, setters, and spaniels, if they are what is termed foul in their coats, never have their scent in perfection. It must be equally evident that, unless they are " in wind," they cannot range with speed and durability ; aud, without some previous training, it is impossible they should be so. Those persons, therefore, who expect su- perior exertion from their dogs in the field, would do well to prepare them by a previous attention to their condition. In greyhounds, intended either for matches, or for simple coursing, .it is evident that this is absolutely necessary to insure success. In simple coursing, they are pitted against • an animal very nearly equal in speed to themselves, and always in condition by its habits. If, therefore, a clog of acknowledged goodness is beaten by a hare, especially at the beginning of the season, it is ten to one but the condition of the dog is at fault. It is self- evident that perfect condition must be more than equally im- portant in coursing matches ; where a dog has two competitors to beat, the hare and the other dog. The manner of getting dogs into condition is- very simple, and either consists in reducing the animal from too full and solt a state, to one of firmness and less bulk; or it consists in raising a lean and reduced dog to lustiness, hardness, and vigour. Some sportsmen prefer the one state, and some the other, to begin upon. If a dog is fat, his treatment must be entered on by physic and sufficient exercise, but not by a privation of food ; 80 EXCESSIVE FATNESS. and it must be particularly observed, that his doses of physic be mild, but more in number. The exercise should be at first gra- dual and slow, but long continued; and at last it should be increased to nearly what he will be accustomed to when hunting. If there is the least foulness (i. e. if the secretions of the skin are impure) apparent in the habit, besides physic and exercise, alteratives should be given also: these medicines immedi- ately follow tbe subject of condition. Some sportsmen regularly dress their dogs, before the hunting season, with sulphur, even though no breaking out appears, and I by no means think the practice a bad one. Others curry or brush their dogs, whether any skin affection appears or not ; and, to greyhounds, it is a very proper means of keeping up the equilibrium of the circula- tion, and of promoting muscular elasticity. When a lean dog is to be got into condition, less physic is necessary ; but good flesh feeding, plenty of exercise, and a due administration of alteratives, are principally to be resorted to : nevertheless, one or two doses of very mild physic will here also promote the condition, and even assist the accumulation of flesh. EXCESSIVE FATNESS. Among the various defects in condition, obesity, or an over- loading of the adipose matter or fat of the body, is one of the most common. A proper plumpness of appearance denotes health ; but when the animal oil becomes inordinately dispro- portionate to the other parts of the body, it proves a source of numerous diseases. The natural tendency of dogs to become fat is considerable, for any dog may be made so by mo- derate feeding only, with little exercise. Provided the accumula- tion has been quick, the dog may be reduced to his former state without prejudice ; but, when a dog gradually accumulates much fat from over-feeding and confinement, then the accumulation itself becomes so completely a disease, that even exercise and abstinence will not always wholly reduce him ; for the formation of the adipose substance is so habitual a work of the constitution, EXCESSIVE FATNESS. 81 that, however little food the animal takes, short of starvation, that' little goes to the formation of animal oil. The truth of this may he known by the notorious fact, that many fat dogs eat but very little. There are, therefore, two sources of obesity; one over-feeding; the other, want of exercise : and when, as is very frequently the case, both causes happen to meet, in the same subject, then the accumulation is certain. When dogs are over-fed, whatever is taken into the body, more than the general secretions require, is either converted into fat, or forms some other unusual secretion ; as a purulent flow from the ears in canker, or scabs on the skin in mange. Exercise increases all the usual secretions ; hence, under strong exercise, more nutriment is required: and thus, in such cases, full feeding does not produce fat; but, even in full exercise, provided some of the usual secretions are stopped, though the others may be in full force, yet an inordinate quantity of animal oil is apt to form: thus spayed bitches and cas- trated dogs usually become fat, however they may work, because in them the sexual secretions are inert. Fat more readily accumulates in middle-aged and old dogs, than in the young ; and the adeps of old dogs is more hurtful to them than that of the young ; the reason of which appears to be, that all aged animals have their fat placed more inwardly, while in the younger ones it is found more upon the surface of the body. A state of excessive fatness is an almost certain fore- runner of asthma. It is also the parent of mange, canker, and other eruptive diseases ; and not unfrequently it occasions epilepsy, from the pressure it produces on the vessels of the head and chest. I have also seen an excessive deposition of fat within the chest, particularly around the heart and large vessels, which has terminated by a rupture of one or the other of them. ALTERATIVES. These various states of want of condition require the use of alteratives : there are also many states in which, although there 82 ALTERATIVES. appears no very serious disease, yet a sufficient remove from health exists to make some alteration in the constitution ne- cessary. When this is the case, the end may, in general, he attained hy these remedies. An actual disease may also exist, whose removal can be best effected by a slow but uniform change, to be wrought in the constitution by what are, from this cir- cumstance, termed alteratives. Hence excessive fatness, chronic coughs, fits, glandular swellings, mange, 8cc. &c. are best at- tacked by these slow but sure means. Various substances are used as alteratives ; as antimonials, and the different ^preparations of mercury, iron, and tin. The nitrate of potash ( nitre ), the supertartrate of potash ( cream of tartar), aloes, salines, &c. &c. &c, are excellent alteratives. Tartarized antimony ( emetic tartar) often proves a very useful alterative in the chronic asthmatic cough to which dogs are subject, given as an emetic once or twice a week, in doses of one grain to three. Antimonial powder, or James's Powder, may be also given with benefit as an alterative in similar cases. Crude antimony- is often found useful in diseases of the skin; but it is unfortunately very uncertain in its operation : that is, some dogs will bear a considerable quantity, while others cannot even take a small one without violent sickness : the usual dose is from half a scruple to half a drachm. Nitrate of potash (nitre) is a very useful alterative to dogs, for hot itching humours and redness of the skin, in doses of four grains to ten. The super- tartrate of potash (cream of tartar) may be also given as an alterative with benefit, in larger doses, in the same cases : all the preparations of mercury, though excellent alteratives, re- quire great caution when frequently repeated, or regularly given ; for dogs are easily salivated, and salivation produces very hurtful effects on them. Dogs, when fully salivated, lose their teeth very early, and their breath continues offensive through life. The whole of the feline tribe are also easily affected by mercury. I was requested to inspect the very large lion that so long graced Pidcock's ALTERATIVES. 83 Menagerie. It may be remembered by many, that this noble animal's tongue constantly hung without bis mouth; which arose from his having been injudiciously salivated, many years before, by a mercurial preparation applied by the keeper for the cure of mange. The submuriate of mercury (calomel) is, like- wise, very irregular in its action on dogs ; I have seen eight grains fail to open the bowels of even a small one, while, on the contrary, I have been called to a pointer, fatally poisoned by ten grains. It forms, however, a useful auxiliary to purgatives, in doses of three or four grains ; and as it not unfrequently acts on the stomach, so it may be used with advantage as an emetic in some cases, particularly in conjunction with tartarized anti- mony (tartar emetic). When, therefore, a purgative is brought up again, in which calomel was a component part, it may be sus- pected to arise from this source, and, if it is necessary to repeat the purge, the mercurial should be omitted. The various preparations of iron form excellent alteratives in some cases of weakness, particularly of the stomach and bowels, for which affections they act best when united with the aromatic bitters. Sulphur is the alterative remedy in the most general use of any ; but its properties in this respect are much over- rated. It is a very common practice to put a roll of brimstone into the pans from whence dogs drink their water ; the impreg- nation of which, by means of the sulphur, is expected to keep the animals in health : but so completely insoluble in water is brimstone in this state, that a roll of it so kept would not lose ten grains of its weight in ten years, nor would it become in the least altered in its quality. Sulphur in powder, or flour of brim- stone, as it is termed, is, however, more active ; but even in this form it often passes through the bowels nearly unchanged : it proves, in other instances, slightly . purgative. In one disease, however, it seldom fails to do good, even unaccompanied by any thing besides, which is the piles, to which complaint many dogs are very subject. In conjunction with other alteratives of the cooling, cleansing kind^ it proves also useful in mangy eruptions, F 84 EMETICS. canker, &C; and I am disposed to think, that one part of supertartrate of potash (cream of tartar), with two parts of sulphur, forms the best alterative that can be given in these cases. Externally applied, the benefits of sulphur are much more apparent, and are too well known to need enumeration. Alteratives are, therefore, of almost universal application, as they are both preventive and remedial ; they prevent the accu- mulation of fat and other matters, as the milk in the teats of bitches, foulness in the skin, congestions in the chest, &o. As remedies, they are adapted to all diseases of long standing, by their gradual action. Emetics. Among the various alteratives, none are more salutary to dogs than emetics : vomition appears almost a natural act m dogs ; at least it is one that they voluntarily excite, by eating emetic vegetables, as the long wild grass, so hurtful to pastures. Dogs, in common with all quadrupeds who eat animal matter, are&subject to irregular digestion and a train of symptoms that we denominate bilious. In the canine species these are par- ticularly prevalent; and dogs appear to be instinctively tauglit to relieve themselves from them by an emetic, which they take more frequently, when they can procure it, than we are aware of. It is evident, therefore, that such as are much con- fined, and those which inhabit large cities, must suffer in their health from the want of this usual evacuation. To remedy tins, when circumstances wholly prevent their reaching the grass, or other emetic vegetables, some of the dog-grass might be brought to them, either gathered, or the roots of it might be placed in pots for their use : in fact, it is sold in Covent Garden for the express purpose. In default of this, a mild occasional vomit, ot tartarised antimony (emetic tartar), or calomel, will become a very proper method of imitating this natural evacuation of the dog; and will tend much to keep such in health as are subjected to heating food, confined air, and little exercise. Emetic tartar EMETICS. 85 may be readily given as a ball ; or it will sometimes be volunta- rily taken in a little milk or broth, or between small slices of meat, or with butter ; in quantity from one grain to three : a very large and strong dog might require four grains. Calomel also, from a grain and a half to four grains, forms a very useful and cleansing emetic, acting, as it usually does, upon both the stomach and bowels. These articles may also be mixed in equal propor- tions, and of the mixture from a grain and a half, as the smallest dose, to four, five, or six grains as a full one, may be given with benefit in any affection where both these intentions are to be fulfilled : in pure febrile cases, it may be prudent to trust to the tartarized antimony alone ; an antimonial emetic being peculiarly called for in these cases by the power it possesses of lessening the action of the heart and arteries. Common salt is also a ready domestic puke for dogs ; the half of a small tea-spoonful being sufficient for one of a diminutive size ; a tea-spoonful for a larger ; and a tea-spoonful and a half for the largest : but it is apt to act violently, and is, therefore, not to be recommended for such as are tender or delicate ; many such having been destroyed by it. Greater objections even may be made to Turpith mineral and crude antimony ; to both of which, however, sportsmen are apt to be very much attached, but without any good reason, for both are very violent in their action : crude antimony is also un- certain. No possible good cau be derived from these drastics, except, Othello like, the poor dogs which take them are after- wards to be loved " for the dangers they have passed." Many are killed outright by them, and many more would share the same fate, were it not that their poisonous emetic qualities are such as often to cause them to be rejected by the stomach almost immediately they are taken. It may be proper to observe, that where calomel, or any of the heavy metallic substances are given to dogs, it should not be done in liquids; for, by falling to the bottom of the vessel, they escape being taken. Mixed up with butter, or enclosed between two thin slices of meat, dogs may often be deceived to take medicines without force, particularly f2 86 LAXATIVES AND PURGATIVES. when the matter mixed is tossed to them ; by which they catch it without smelling it : for so keen is their scenting quality, that otherwise, they will be very apt to detect the attempted decep- tion ; and some will even be timid for a long time afterwards of receiving any thing offered by the hands. Laxatives and Purgatives. These evacuants are both preventive and curative of disease : they are valuable alteratives, and active immediate agents in acute affections. By opening the bowels, we remove a. frequent cause of irritation to the system; and a very considerable source of skin affections also ; for whatever is taken up superfluously by the system is apt to find itself an outlet there. We thereby like- wise prevent pulmonary congestion, and deposits of fat. which would obstruct the visceral functions. Laxatives are good pre- ventives against that habitual costiveness common to dogs, and all other carnivorous animals : such, therefore, as are flesh-fed should have this tendency obviated by laxatives ; and the best which offers itself is a portion of vegetable matter with their flesh food : potatoes, or even greens, can always be procured, and will answer the purpose. This is the more necessary, for costiveness sometimes occasions fatal obstructions ; and a costive habit brings on fistulee, and also affords encouragement to the breeding of worms.— Medicinal laxatives are numerous. Epsom salts (sulphate of magnesia), dose one drachm to two; castor oil, two drachms to four ; syrup of buckthorn, the same quantity ; will either of them answer this end, the quantities being increased if those mentioned are not found sufficient : but as these direc- tions are intended to meet the tender pet of the drawing-room, as well as the strong inhabitant of the kennel, so it is prudent to specify the minor dose : more may be added, but it is too late to subtract when too much has been given. Purgatives may be made by increasing the doses of any of the laxatives. Jalap is not a bad purgative to dogs, hut it is uncer- tain, some being little affected by it; rhubarb is equally so; LAXATIVES AND PURGATIVES. 87 senna I have no experience of; gamboge is very drastic ; calomel is an excellent auxiliary to other purgatives on some occasions ; but given alone it is apt to deceive, by proving more emetic than purgative : neither will the stomach or bowels bear a sufficient quantity without producing much derangement in the system, as violent vomiting, tenesmus, and sometimes sudden salivation. Aloes form the safest general purge to dogs ; and such are the peculiarities of the canine bowels, that while a man can take with impunity as much calomel as would kill two large dogs, a mode- rate sized dog will take a quantity of aloes sufficient to destroy two stout men. The smallest dog can take fifteen or twenty grains ; half a drachm is seldom too much, but the smaller dose had better be tried first : medium sized dogs usually require a drachm, and some large dogs have taken more than two drachms : I have given three to a strong Newfoundland dog without ex- traordinary active catharsis ; but, as before observed, dogs differ much in their different habits, and it is therefore most prudent to begin with a dose too small than one too large: hundreds of dogs are every year destroyed by temei-ity in this particular. The Mastiff Pug, or supposed origin of the Hull Dog, p. 26. 88 LAXATIVES AND PURGATIVES. Whenever a purgative is given, let the dog have some vegetable food, if possible, a day or two previously ; an active cathartic, given soon after a full meal of flesh or bones, might destroy by hurrying the undigested food into the intestines, where it might form such an impacted and obstructing mass as could not be overcome. Likewise, when a purgative has been given, it is prudent to place before the dog some broth, milk, &c, to assist purgation. Let me warn sportsmen who are putting their dogs through a course of physic, for hunting, or coursing purposes, to be aware, that it is not the inordinate strength of the dose which does good ; on the contrary, violent physic defeats its own pur- pose : it is a mild and repeated emptying of the bowels which unloads the system at large, and at once strengthens the solids and purifies the fluids. PART THE THIRD. THE DISEASES OF DOGS. GENERAL TREATMENT OF DOGS UNDER DISEASE. I SHALL commence the subject with making some observa- tions on the diseases of dogs generally ; and with offering some practical directions applicable to the principal of them. The dog I have already shewn to be partially an omnivorous animal. Man is decidedly omnivorous, and, as might be expected, a great likeness exists between their organs of assimilation, which extends itself into their diseases also, the human and canine maladies running a remarkable parallel together. This similarity of dis- ease does not, however, equally extend to all the domestic ani- mals around us. The sequine and human diseases have numerous dissimilarities ; the bovine still move, and consequently the dis- eases of the dog must be studied distinctly from the other branches of veterinary inquiry : to which circumstance we must attribute the lamentable state of canine pathology until now. The human practitioner, from this striking similitude of disease, might often safely and beneficially prescribe for the dog, while the veterinarian is precluded by the specialities alluded to. Un- fortunately, however, the one has often thought the matter be- neath him, while the other found it above him ; and thus between the two, the poor dog has been too often neglected. The time is, however, hastening, when this valuable servant of man will find auccour in his hour of need : these pages, I believe, have done something for him : he has a warm and able friend in the 90 GENERAL TREATMENT humane and ingenious Mr. Youatt (see the end of this article). Nor will the medical treatment of the dog hereafter fail to form a part of the course of instruction in the St. Pancras Institution. It is likewise no less true than curious, that not only do the maladies of the canine race very nearly resemble those of the hu- man species, in cause, appearance, and effect ; but the similarity is extended to the number and variety of them also, as may be seen by a reference to the nosological catalogue, where many complaints will be found that have no existence among other do- mestic animals. These affinities will, however, cease to excite wonder when we consider that, in addition to the complexity of structure in dogs, their complete domestication has subjected them to lives wholly artificial, and, in many instances, to habits the most unhealthy. It is not, however, in every case, that these analogies would enable the human practitioner to judge of or prescribe for the diseases of the dog : on the contrary, in many instances, the most acute physician and the most able veterina- rian would be equally at a loss without a previous acquaintance with canine pathology. Among other sources of difficulty to both, the canine specific diseases may be quoted, which are nei- ther met with in the human, or the ordinary veterinary practice : another important deviation from the line of both practices arises fr om the very different effects that some of the remedies employed by both would have when administered to the dog. Fifteen grains of emetic tartar would probably destroy any dog; five hundred could be given to a horse without injury. Ten grains of calomel, though a full dose, is by no means a de- structive one to a human subject ; yet I have seen a large pointer killed by this quantity, which had been ordered by an eminent surgeon : even three or four grains will often puke violently, and twice the quantity will often fail to purge : twenty times the quantity would fail to do one or the other in the horse. On the other hand, three drachms of aloes, which would probably prove fatal to nine human persons out of ten, might be taken by some large dogs with impunity. A dog could take, without any OF DOGS UNDER DISEASE. 91 derangement, a dose of opium which would destroy a man ; on the contrary, the quantity of nux vomica, or cro wfig, that would de- stroy the largest dog, would fail to destroy a man. A very small quantity of oil of turpentine will kill a dog ; when in human prac- tice, a considerable dose is frequently given as a vermifuge1. Between the effects produced by many medicinal articles on the stomachs of other domestic animals, and that of the dog, a still more marked distinction, or, at least, a more universal one, exists. Without knowing better, one might be misled by the accounts we read, and hear from sportsmen, of the monstrous doses they give of some medicines : the fact is, the stomach re- jects it at once,— a dog is soon vomited, and thus is not de- stroyed ; give him half the quantity, and it would kill, because it might not be immediately rejected. It will therefore be evident, that neither the human physician nor the veterinary practi- tioner can be equal to a successful medical practice on dogs, without much attention to the subject, and much experience in it. It adds to our difficulty in collecting the diagnostic signs of dis- ease, that our patient, like the human infant, cannot speak : with dogs, nothing but very long habit of observation of these appear- ances in a vast number of cases, united with a natural quickness i The critic should beware sometimes when he wields the lash, for fear the stroke may recoil. When this work first appeared, and was reviewed, great surprise was expressed, because I had made so palpable an omission, as not to insert oil of turpentine as a vermifuge for the dog. Perhaps the reviewer was the same gentleman noticed by Mr. Youatt, in The Veterinarian, No. 13, p. 11, who gave one or two drachms of it to a stout spaniel for tape-worm, which destroyed him instantly. In a late sporting work of great volume, we find it also recommended to give half a pint of linseed oil and two drachms of oil of turpentine as a " sovereign remedy" for worms. It would be no easy matter to get the quantity down, and the quality of the turpentine would in all probability kill : the same work recommends, as a cure for fits, from two to eight grains of tartar emetic. Very few dogs would survive the taking of the larger dose. I saw a large and valuable dog destroyed by ten grains, given at the instance of a veterinary surgeon even. It is much to be regretted, that gentlemen and authors are so ready to offer medical instructions on matters they know nothing about. There is certainly no more reason why the most, finished sportsmen should be able to prescribe for the diseases of horses or dogs, than that their valets who attend on them, or the barber who shaves them* should understand their diseases. 92 GENERAL TREATMENT of perception, can enable the practitioner, in very many cases, to arrive at a just conclusion. The symptomatology of canine dis- ease is necessarily diffused through the manifestations of the indi- vidual ailment. As in the human, and other brute subjects, wii regard the state of the circulation by the pulse2, and by the ratio of respiration. We examine into the state of the excretions when in our power, and we attentively examine by the eye, and the touch, every part of the body ; by which we often gain much information that the fears or the patience of the animal might conceal. We ought also to examine the eyes and tongue, the one, as indicatory of both inflammation and hepatic effusion, and the other, of affection of the alimentary canal: nothing is to be done without experience, and a professed and particular attention to the subject. When, also, the existing disease has been ascer- tained, and the appropriate treatment has been determined on, still another difficulty often presents itself ; which is, how to ad- minister the remedy. Now and then, dogs prove very refractory, and no small degree of force is necessary to get any medicine down. In general cases, however, a slight degree of dexterity 2 The pulse of the dog may be felt by the heart, and at various points of both the fore and hind legs, but particularly at the inner side of the protuberant callosity of the carpus or knee. The range of pulsation between a very large and a very small dog is not less than 20; thus, if 100 be taken as the usual number of the first, and 120 for the latter, whatever is found to much exceed this, may be usually laid to the account of an inflammatory state. It must, how- ever, be observed, that from the greater irritability of lesser animals compared with the larger, and the extreme quickness of their circulation, the motions of the heart and arteries do not present such exact criteria of health and disease as they do in the horse and other large animals. Nevertheless, the action of the heart, and the pulsations of the larger arteries, may be felt with propriety in many cases, and will serve as some guide to ascertain the degree of excitement. The pulsations will not only be increased in quickness, but they will present a vibratory feel in violent inflammatory affections. In inflammations of the lungs they will be very quick and small, but will increase in fulness as the blood flows dining bleeding. Something like the same will occur, but not in an equal de- gree, in inflammations of the stomach and bowels also. As the pulsatory mo- tions, therefore, are not so distinct in the dog as they are in larger animals, so, in general, the state of the breathing, which, in most cases, is regulated by the circulation, may be principally attended to as a mark of greater or less inflam- matory action. When a dog, therefore, pants violently, his circulation, or in other words his pulse, may be considered as quickened. OF DOGS UNDER DISEASE. will accomplish the purpose, the particulars of which are detailed below3. Dags under disease are very tender animals, and require very great attention and care to insure their recovery : it is, however, too common with many persons to neglect them under these cir- cumstances; and if they are placed in a cold room, or an out- house, with stale or broken victuals and water placed before them, it is frequently all the attention they experience : unless, perhaps, to all this maybe added, something of doubtful effi- cacy as a remedy. But when we consider how very tender many of these animals are rendered by confinement and artificial habits, it will be clear that, under sickness, they must require peculiar care and attention. Warmth seems particularly congenial to the feelings of sick dogs, and is often of more consequence to 3 The best method of administering remedies—Place the dog upright on his hind legs, between the knees of a seated person, with his back inwards (a very small dog may be taken altogether into the lap). Apply a napkin round his shoulders? bringing it forwards over the fore legs, by winch they become secured from resisting. The mouth being now forced open by the pressure of the fore finger and thumb upon the lips of the upper jaw, the medicine can bo conveniently introduced with the other hand, and passed sufhciently far into the throat to insure its not being returned. The mouth should now be closed and it should be kept so, until the matter given has been seen to pass down. When the animal is too strong to be managed by one person, another assistant is re- quisite to hold open the mouth; which, if the subject is very refractory, is best effected by a strong piece of tape applied behind the holders or fangs of each jaT'he difference between giving liquid and solid medicines is not considerable A ball or bolus should be passed completely over the root ot the tongue, and dexterously pushed some way backwards and downwards. When a liquid remedy is given, if the quantity is more than can be swallowed at one effort, it should be removed from the mouth between each deglutition, or the dog may be strangled. The head should also be completely secured, and a little ele- vated to prevent the liquid remedy from again running out. Balls of a soft consistence, and those composed of nauseous ingredients, should be wrapped in silver or other thin paper, and greased, or they may occasion so much disgust as to be returned. Medicines wholly without taste, as mercurials, antimonials, &c may be frequently given in the food; but sometimes a considerable incon- venience attends this, which is, that if the deception is discovered by the dog, he will obstinately refuse his food for some time afterwards. The purging salts may also be sometimes given in food, being mistaken by the animal for the sapid effect produced by common salt. 94 GENERAL TREATMENT their recovery than is imagined : many of their diseases degene- rate into convulsions when they themselves are exposed to cold. Cleanliness of every kind, and a change of their litter or bed par- ticularly, is very grateful to them in many cases of putridity, as in distemper, &c. Complaints purely inflammatory, it is evident, must be treated by abstinence ; but, in all others, the weakness present must be combated by nutritious aliment. It is not sufficient, as is often imagined, that food, particularly of the common kind, be merely placed before a sick dog. In many such cases, the appetite wholly fails ; and, if even the ani- mal could eat, the stomach would not at this time digest hard meat, or any of the common matters usually given to dogs. In these instances, nourishment is best received from strong broths, gravy, jelly, or gruel ; or, perhaps, best of all, from thick gruel and a strong animal jelly, mixed ; for I have always remarked, that no simple liquid will afford equal nutriment with one thickened with flour or other meal. Sick dogs are also very fan- ciful, and often require enticing to eat, by the same arts we use towards children. Fresh meat of any kind, but very lightly broiled, will sometimes tempt them. At others, pork in particu- lar is highly relished ; while, in some cases, raw meat alone will be taken4. But in almost all cases, if the slightest inclination for food remains, horse-flesh, lightly dressed, will be found irresisti- ble, so great is their preference for this food. The extreme fickleness of their appetite, when sick, makes it necessary that every kind of edible should be tried, as that which is voluntarily taken will always digest more readily than that which is forcibly given ; still bearing in mind, that as support is essential, parti- cularly in all illnesses of long continuance, so, when food is ob- stinately refused, nourishment should be forced down. In cases requiring active cordials, ale may be mixed with gruel or gravy : wine is seldom advisable, from its disposition to inflame the 4 Sir Astley Cooper instituted a course of experiments to determine the de- gree of solubility, by digestion, in various meats within the stomach of dogs ; when the result was greatly in favour of the digestible properties of bacon and pork. OP DOGS UNDER DISEASE. ^5 bowels. I have, however, now and then used it with benefit in highly putrid cases of distemper ; in which instances forced-meat balls also prove both nutritious and cordial. The intensity of mental feeling in the dog is at all times great, but under disease it appears doubled ; and although it may, to a superficial observer, look like an affectation of tenderness, it is a very necessary caution to observe, that at these times their, minds should be soothed by every means in the power of those around them. Harshness of manner and unkind treatment, in many instances, very evidently aggravate their complaints : under some diseases, their irritability of mind is particularly apparent; of which distemper is a very prominent example. I have several times witnessed an angry word spoken to an healthy dog produce instant convulsions in a distempered one who happened to be near; and the tits that come on spontaneously in distemper, almost instantly leave the dog by soothing notice, so open are they to mental impressions. Joy and surprise will also often prove equally injurious to them when they are very weak. Even among those who conceive themselves minutely acquainted with dogs (and who probably are so with the sporting kinds, and with such as lead more natural lives in the open air of the country, with the advantages of moderate feeding and due exercise) there will be many who will regard these extreme cautions as unneces- sary. The number and variety of the diseases quoted will also probably excite their surprise ; and, unaware of the existence even of many of them, they will be apt to consider the diversity of symptomatic appearances described, the cautions insisted on, and the minuteness of detail in the medical treatment, as, in a great degree, superfluous : but a little further inquiry will satisfy such, that no animals can differ more widely than the dogs they are accustomed to, and those that are born, bred, and perhaps constantly reside in cities, towns, or other close situations. These instructions are necessarily confined to no one meridian : as well as the more healthy country animal, they embrace also the pet, and pampered favourite, that is perhaps immured, twenty- three out of the twenty-four hours, in a hot drawing or bed-room, PROFESSIONAL ATTENDANCE, &c. breathing the same confined air, eating the same luxurious food, and exercising in the same easy carriage, with his owner. A life so wholly artificial alters the mental and bodily properties to such a degree, of such as are subjected to it, that their constitutional tendency to disease is almost as great as that of those they belong to : under disease their irritability is nearly equal, the diversi- ties of their symptoms alike numerous ; and, consequently, they require every portion of that caution and attention I have pre- scribed to insure their recovery. PROFESSIONAL ATTENDANCE AND ADVICE FOR DOGS. I presume I hardly need to further inform the proprietors of dogs, that no written instructions can meet every case ; the va- riations in disease, the anomalies attending the symptoms ac- companying it, and the impropriety of giving even the most accredited remedies in particular cases, all require the judgment of a medical practitioner. Neither, I presume, is it necessary, after what has been observed on the peculiarities of the canine constitution, to insist much on the little certainty of deriving be- nefit from even professional attendance, unless such professional attendant should have made the diseases of dogs an object of par- ticular inquiry. Fortunately for the race, Mr. Youatt, who first studied under me, and who has since far outstripped his master, offers a ready acquirement of canine pathology, by making his Public Lectures at his own Theatre, as well as at the London University, embrace the diseases of Dogs, to which subject it is well known he has for many years successfully given his attention. His humane endeavours are, therefore, directed to qualify future veterinarians for this unique practice, as well as to fill up the present gap, by lending his professional aid to the animal himself, cither by personal attendance, or written consultation ; and I should fail in my duty to the cause of humanity, to the possessors of clogs, and to Mr. Youatt also, if I did not strongly recommend application to be made to him, wherever interest is excited with regard to the health of any domestic animal what- INFLAMMATORY AFFECTIONS. 1)7 ever, but of the subject of my present pleading (the dog) in par- ticular.

Idiopathic or Primary Fever is not very apparent in the dog, although our present knowledge will not allow us to deny its occasional existence. We are, however, certain, that if it ever does exist in its simple and uncombined state, it does not often remain so ; but is usually, in its early stage, translated to some individual organ, or set of organs, and then runs its course as symptomatic fever, which is by no means uncommon in the dog : on the contrary, prominent instances are offered us in the fever of distemper, and in the fever of rabies ; in both of which there is evidently, throughout the system generally, a state of dif- fused inflammatory action : and although both of these partake of the nature of specific affections, yet the anomalous symptoms of each are such as to render it difficult to fix their original seat of attack, or to establish their true characters. Sub-Class I. Inflammation of Mucous Membranes. SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. The Distemper, as characterizing an individual disease, though a very absurd and indefinite term, is become so conventional, that it is not easy to rid our descriptions of it. It is thought to have gained this name from the same source that we derived the disease itself, the French ; with whom it is called La Maladie. It is, however, possible that it was called distemper alter the 98 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. epidemic catarrh of horses, which being a common complaint long known by that name, and in some respects not unlike it, might readily occasion it to be so called. This scourge to the canine race, now so general, does not appear to have been known a century ago5 ; and throughout the European continent it was, until lately, described rather as an occasional epidemic which visits the different countries every three or four years, than as a settled constitutional guest among dogs, like the glanders of horses, or the measles or hooping cough in the human6. Our continental neighbours appear to have transmitted it to Eng- land : and here also it seems first to have appeared rather under the type of an accidental epidemic, but which is now be- come, by some morbid combinations, a permanent disease, to which every individual of the canine race has a strong inherent liability. That we imported it, is evident from the circumstance, that the earliest notices we have of it in English sporting works 5 In opposition to this late appearance of the distemper, it has been con- jectured that it was not unknown to the ancients, and was called the Angina, being one of three diseases to which dogs, according to them, were liable ; Madness and Podagra forming the other two. But an attentive examination of the symptoms, as detailed by Aristotle, .Elian, and such other ancient authors as have left us their observations on the canine race, will clearly shew that the distemper, as it is known among us, was unknown to them. Their angina appears to have been an accidental epidemic, which confined iis attacks almost wholly to the throat, producing in us imposthumes, like quinsy in the human; but the grand characteristic, of primary and continued dis- charge from the nasal mucous membranes, is wholly unnoticed.— See JElian deNal. Animal, lib. iv, c. 40; Aristotle Hid. Animal, lib. viii, c. 22, &c. &c. 6 In the Grand Encyclopedic MUhodique the disease is thus described: "II c'est jette, il y a quelque annees, une inaladie epideinique sur les chiens ''dans toute l'Europe; il en est inort une grand partie sans que Ton put "trouver de remede au mal."— Livraison LIX Chasses. In the Diet. Vet. of H. D'Arboval, we also read, "Selon quelques personnes, il n'y a pas long-temps que l'on connait cette maladie en Europe, et ce serait seulement vers le milieu du siecle dormir qu'elle s'y serait manifested ; quelque auteurs pretendcut memo qu'elle a ete importee d'Angleterre en Fi ance en 176!); cependant on se rappelle qu'au mois de Mars 1714, on l'a vue regner comme epizootiquement dans nos provinces meridionales, avec complication d'angiiie gangriineuse.

SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 9Q are subsequent to its announcement in the pages of similar con- tinental publications ; and though a few among their writers affect to attribute it to British origin, the best informed think otherwise. It is a disease of the most protean character, as- suming such different appearances, and exhibiting such anoma- lous symptoms, as to render it extremely difficult to define ; and until, by a long and diversified series of experiences, we have been able to separate its true pathognomonic from its occasional symptomatic phenomena, it is in vain to expect it. The few writers who have noticed it among ourselves offer full proof how little is really known of it? : and with our neighbours, the French, the discordances in opinion relative to it, are more than equal to our own ; numerous as have been the individuals among them who have made an object of inquiry. Mon6. Hurtrel D'Arboval, the best veterinary gleaner the continental field produces, bears me out in this assertion8. Notwithstanding the fixed and per- 7 Dr. Darwin, it is true, characterized it as a debilitating patarrh ; but it is evident he took a very superficial view of its whole nature and conse- quences, when he considered the only treatment necessary, was, that the air should be allowed to p:iss freely over the ulcerated surfaces of the nose. If the schneiderian membranes were the sole seat of the disease, there might be some shew of pathological reasoning in this; but as an early participation is made either with the lungs, the intestines, or the brain, from which it derives some of its strongest characters, so it is evident the rationale of Dr. Darwin falls to the ground. The further absurdity of directing that distempered dogs should be allowed to drink from a stream, that the contagious mucus of the nostrils, having escaped one passage, may not again enter another, and thus re-poison the dog, also proves his erroneous vjews of it. The philanthropy of Dr. Jenner induced him to turn his attention to the same subject, in hopes to ward off its consequences by vaccination; in consequence of which he has drawn an outline (in vol. 1 of Med. and Ckirurg. Tracts) of a disease which is, as well observed by Mr. Youatt, " made up of distemper and rabies, and unlike both." 8 " Plusieurs auteurs 1'ont en outre consk'cree comme upe espece de gourme, romme une maladie depuratoirc, comme le resultat d'une crise salutaire qui debarrasse la nature, et on I'a comparee a. la gourine des solip&des, et a IS pe- tite-verole de Pcspece humaine.

It is likewise endemial, and attacks the dogs of a particular district, leaving others comparatively free. When it shews itself as an epidemic, its versatility of character in dif- ferent seasons is often remarkable. I have seen it accompanied with marked biliary affection in every dog attacked that season : many of the cases of that period had also a pustular eruption. 1 have seen it also make its appearance, in a few instances during one particular period, by a phlegmonous tumour of some part of the body, but principally of the head. In the summer of 1805, many of the distempered subjects were attacked with a peculiar and painful spasmodic colic, which neither constipated nor re- laxed the bowels ; but after continuing acute two or three days, usually terminated fatally. In the few cases which ended favour- ably, active purgatives of calomel and aloes appeared beneficial.

Neither an. I at all aware that it has ever been seen in the fox : there is a vulpine mange with- out doubt; but whether a s/urijir catarrh exists also, is not, I bel.eve, known among us. SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 101 that whenever distemper rages as an epidemic, it commonly as- sumes some particular characteristic type, without its usual ver- satility. One year shall be remarkable for the harassing' and ob- stinate diarrhoea that appears ; another for the more than usual tendency to epilepsy and spasm ; while in a third, a malignant putrid type will sweep off most of those affected. Causes. — Constitutional liability may be reckoned as a princi- pal among these ; and it is so inherent in the canine constitution, that very few escape it altogether, the predisposition alone being itself sufficient to generate it, although it is probably more fre- quently assisted by some occasional cause, as cold, &c. Conta- gion is another fruitful source of it ; and however a few persons may doubt the contagious nature of distemper, those who have taken the pains to examine the matter, are as convinced of it as the force of facts can make them. Dogs living out of doors principally, and which are thereby rendered healthy and hardy, will sometimes bear up against the predisposition for a long period, and some as long as they live ; but such even, if they become exposed either to the effluvia, or to the contact of the morbid secretions on a mucous or an ulcerated surface, very seldom escape it. In many cases, the slightest application of it, or even being exposed to the air impregnated with the exhalations from a distempered dog for a few minutes, is sufficient for the purpose. As it is communicable by the contact of the diseased catarrhal secretion, it may be supposed that purposed inoculation readily introduces it into the system, and such is the fact. Ne- vertheless, at times the constitution is not open to receive the contagion, and not only will inoculation fail to produce it, but also constant communication, and every other means whereby it might be supposed communicable. At some future time, how- ever, the disease will be readily produced in the same dog, by apparently less active agencies. The occasional causes are nu- merous: whatever tends to produce debility in the system is a grand one ; thus distemper frecpiently follows other diseases, as pneumonic attacks : the confinement and treatment which bad o 2 102 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. mange requires is observed to produce it also ; and the tabid and ricketty very rarely escape it in its severest form10. Cold acci- dentally applied, as washing without drying afterwards, or throw- ing a puppy or young dog into the water, has often brought it on ; forcing such a one to sleep exposed, does the same. Sudden haemorrhages, and an immediate change from a full to a low diet, or an unusual day's fatigue, are each of them causes that I have seen produce distemper11. The period of its attack follows the same uncertainty as marks its other phenomena. I have known it to affect puppies of a few weeks old, where it might be supposed that the constitutional predisposition alone could have produced it : this occurs parti- cularly to the diminutive breeds, as pugs, very small spaniels, pigmy terriers, Italian greyhounds, and other minute varieties ; in which cases it is almost invariably fatal. It more commonly, however, makes its appearance between six and twelve months : among country dogs it is protracted to the period of 'full growth often ; but no age is exempt from it, and it is not uncommon to see it in three, four, or five year old dogs, with which it usually proves extremely severe. Neither is its attack confined to once ; it will now and then appear not only a second, but a third time 10 Mr. Youatt observes the same also. " When (he says) I see a puppy with man«re, and that peculiar disease in which the skin becomes corrugated, and more" especially if it be a spaniel, and pot-bellied or ricketty, I generally say I can cure the mange, but that the dog will soon after die of distemper: and it so happens in three cases out of torn."— Veterinarian, No. 26, p. 76. i' The French entertain an opinion, that feeding dogs on animal food is pro- ductive of distemper. At the Parisian Veterinary School the whelps of a bite* were divided; one half were fed on raw meat, and the other half on soup and , eo-etables. Of the first division each contracted the distemper ; of the latter one only became affected, and that slightly ; which circumstance was thought confirmatory of the opinion ; but it is not difficult to prove that tins concha , is neither consistent with reason nor fact. We know dogs to be naturall, a, - nivorous ; and it is not reasonable to suppose, that feeding them after the method which nature pointed out would render them more obnoxious to disease It » likewise in direct contradiction to fact, because nothing so tends to keep off distemper as flesh feeding and high condition. I have invariably observed that the fattest puppies bore up longest against the disease, and weathered it best when it did arrive. SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 103 even, an instance of which fell under my own notice, where I was assured by a lady of great respectability that a very favourite dog, then very ill of the disease, had been twice before distempered with the same, with intervals of two years be- tween each attack, the first of which was, if my memory serves me aright, in France, the second in India, and at last the cruel complaint carried off this faithful companion of an affectionate mistress in England. The dogs used in rural economy, and yard dogs, are not treated by it with equal virulence ; but wherever man has interfered in forcing an artificial breed, and in maintaining and perfecting a degree of forced excellence, there the disease is always severe. It is thus that it is so fatal to high bred hounds, pointers, setters, and spaniels ; and to terriers and greyhounds it is even more so. Mr. Youatt observes, that few dogs imported into this country as exotics do well with it ; thus the greater part of the northern dogs brought by Captain Parry were carried off by it within a twelvemonth. Some breeds possess an hereditary tendency to have it worse than others of the same kind : litter after litter of some sporting strains will hardly yield more than one or two survivors. In such case, I would advise the breeder to cross the race, or to altogether try a new one. Symptoms. — These are marked throughout with such variety, that it is not easy to set before the reader any strictly diagnostic sign or signs : even the nasal defluxion, so common to the com- plaint, does not always appear, until the distemper has made some progress ; and sometimes also in the midst of its most fatal course it is arrested. Nevertheless there are certain symptoms of distemper usually present in most of its cases. One of the earliest of these is a short, dry, husky cough, which is followed by a lessening of the appetite, of the flesh, strength, and spirits : the coat also begins to stare, and the eyes to wink in a full light, as though painfully affected by it: they also, if observed in the morning, exhibit the remains of a little hardened mucus, which may be seen adhering to the inner corner of each, while a 104 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. general cloudiness of the cornea steals over its surface : the nose also is bedewed with a watery discharge, greater or less, as the membranous linings of the orbits and nasal cavities are more or less inflamed ; in which state it may sometimes remain for two or three weeks without much alteration ; it eventually, however, increases, and changes from a limpid watery fluid to a muco- purulent discharge, which flows down the face from the inner corner of each eye ; and, as the disease becomes more intense, it frequently glues up the lids during the night, and blinds the dog, until his efforts have opened them. The nasal discharge, which is first thin and watery, becomes muco-purulent, and next one of direct pus, by which his nose is no less closed up each morning, by the viscid exudation, than his eyes. As the intensity of the mucous inflammation extends, the cough also, which was at first a slight huskiness of expiratory effort only (or perhaps hardly existed at all, for in some cases but little cough attends the early stages), increases to a distressing, harsh-sounding, and frequent attempt at forcing something up from the throat, by an effort that appears compounded of coughing and vomiting. To these appearances are usually added, wasting, weakness, listless- ness, and lessening of the appetite also. Thus far the symptoms detailed bespeak a true catarrhal affec- tion, in the popular and usual acceptation of the term; by which is understood, an inflammation of the air-passages productive of defluxion. But as the true etymology of catarrh extends to in- flammation of the mucous surfaces of the body generally, and as distemper deserves the full extent of signification, we shall now have to follow it as it extends itself over the one or the other of these mucous surfaces principally ; or as it diffuses itself uni- versally through the whole : dependent on which election, are the various types which the future progress of the disease assumes. The transmission of the affection to the brain or its meninges, we are led to suppose takes place, not only by the epileptic symptoms of some cases, or the chorea and paralysis of others ; SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 105 but even more certainly by tbe morbid appearances which pre- sent themselves after death. HoAvever, whether this occurs by continuity of substance, or by metastasis, we are not aware; although analogically it may be supposed to be by the former, in which case the inflammation may shape its course from the orbitary fossas, or it may follow the more likely track of the pituitary sinuses. It is not, however, unlikely, that in some few cases a true metastasis does occur ; for we • occasionally have a very sudden attack of epilepsy, without any of those premonitory symptoms which usually predict, with malign certainty, the distempered fits ; and there is more reason to conclude this, for a single fit, not followed up by another, particularly when it appears early in the complaint, is often not injurious ; and there- fore we may suppose it the consequence of a sudden metastasis, which as quickly returns to its original seat. In the ophthalmia and acute founder of horses, and in the gout of the human sub- ject, these rapid transitions of disease are not uncommon. Our knowledge of cerebral affections is very confined ; but we have reason to suppose that the nature of morbid attacks on the sensorium and its dependencies, are varied like those of other organs. Probably also much may depend on the immediate portion affected, as whether it be the cerebral substance or its matrices : nor is^ it, therefore, unreasonable to conclude, that to this it is owing that the nervous affections which accompany the disease are of such different complexions. The early listlessness, the general prostration of strength apparent in all, unquestion- ably spring from the want of due administration of healthy nervous energy ; but the phenomena that are here hinted at, are the consequence of a morbid energy, that is sometimes partial ; in which case it is possible that the spinal brain is principally affected : sometimes it is total, when we may conclude that the cranial brain is the seat of attack. Under this view, we are not surprised to observe in some distempered cases, that the nervous weakness is confined to the loins and hinder extremities ; and, while the dog is strong and active in his fore parts, the debility 10() SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. of the hinder makes him totter, aiid almost drag the remaindei of his body after him. Again, at other times, this paralytic affection is more universal, and affects all the limbs, and occa- sionally the head likewise ; when the poor brute reels about as though he were drunk. Neither of these paralytic states, pro- vided they are not followed up by more active symptoms, are of necessity or certainty fatal, but, on the contrary, often prove temporary only. In some cases, the nervous affection, instead of being paralytic, is one of true chorea, or St. Vitus's dance : a convulsive twitching attacks sometimes the head, sometimes one limb, less frequently is it universal from the first, but it often becomes so, doubling up the animal into the most extra- ordinary contortions. If these spasms increase in intensity, they will affect him as well when he lies down as when he stands, and asleep as well as awake: in this case he dies a miserable death from sensorial and muscular exhaustion. This affection, how ever* is likewise not necessarily fatal in itself; for although it may accompany the complaint throughout, it will often slowly disappear : but unfortunately it is too apt to end in fatal convulsions ; and when it does not do this, it sometimes continues through life.— See Chorea, Class II. The symptomatic epilepsy of distemper, or Jits, may often be predicted with tolerable certainty, one, two, or three days before they come on ; when, if judicious means are resorted to, they may be often averted ; but, having once occurred, and the first fit being followed up by another within two or three days, it is Very sddom indeed that any hope is left. The precursory symptoms are such as betoken a highly increased, though morbid energy in the sensorium From an emaciated, weak, and spirit- less state, the dog becomes cheerful and alert; his dim and watery, or purulent eyes, become clear, and sparkle with anima tion ; and if attentively viewed, the pupil towards its bottom presents an internal reddening of a fiery aspect; the nasal dis- charge, likewise, frequently either lessens, or is wholly sus- pended, and a momentary check to the accompanying diarrhoea SPECIFIC CATARRHAL DISEASE^ OR DISTEMPEli. 107 occurs sometimes also. How far these latter circumstances are in any way concerned in producing the epilepsy may be with some a matter of doubt; but the sudden cessation of these morbid discharges can be readily accounted for by the increase of the nervous power, which gives, for a time, new life to the diseased parts: and this view appears most, correct, for as the symptomatic tokens of morbid energy precede the stoppage of the discharge, or are at least coeval with it, it would be placing effect before cause to conclude otherwise. It is worthy of re- mark, that the more active symptoms of the epileptic attack are often likewise preceded by a series of spasmodic irritations, which commence at the seat of sensation : thus it is very com- mon for a day, sometimes for two or three days previously, to observe a convulsive twitching of the eyelids, or of the lips or lace, which increases to a quivering of the lower jaw, such as we often witness in dogs eagerly watching the food preparing for them, or when expecting any wished for object, as the going out of the sportsman who has been harnessing for the field in Sep- tember. Here again the symptoms are identified with excite- ment of the nervous energy. These spasmodic irritations, how- ever trifling at first, soon increase to a direct convulsive champ- ing of the whole mouth, as though something unpleasant in it was attempted to be got rid of: during this action, the poor animal stands distressed, though somewhat unconscious. The sensorial excitability is now arrived at such a height as to be readily acted on by trifling accidental circumstances ; thus an angry word spoken to the dog, a sharp rebuke to another, or the sHit of one in a tit, will be often sufficient to bring one on him also. It is by an observance of this effect that we are likewise able to understand why fondling or encouraging a dog under these primary attacks, will shorten the duration, and sometimes stop the fit altogether ; and also we learn why the sudden sti- mulus brought on by dashing cold water in the face will often do the same; which practice should always therefore be resorted to on these occasions. When the epileptic fits, however, have 108 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. gained their full hold on the dog, these means usually fail. A partial or total mental alienation now takes place : when total, the poor brute is often perfectly phrenitic ; lie waters and dungs unconsciously, he tears up the ground, bites every thing around him, and not unfrequently himself also. When the fit is over, he shakes himself, and looks and acts as usual, unless the attacks have been very violent and long continued, when they leave him greatly exhausted and dispirited. The second, third, or fourth day from the first appearance of these violent fits, particularly when they recur every hour or two, commonly closes the scene, the animal being worn down by the additional strength and increased frequency of each succeeding spasm. Tt is during one of these fits, that a dog is apt to be sacrificed under a suspicion of madness; but the suddenness of the seizure ought to inform the looker-on of the total impossibility of its being rabies, which is always, in the worst cases, marked with some recollection, some knowledge, and which never exhibits the indiscriminate fury which characterizes epilepsy. See Rabies, Class VIII. In another form of epileptic fit, the dog is seen to walk round and round, his steps usually directed to one side only, with measured and solemn pace, but in general wholly unconscious to every thing around. This is not a very frequent form of the nervous affection ; but I have seen several instances of it, all of which proved fatal. Query, may not this be con- sidered as a partial attack on the brain, principally directed to one side of it ? Pneumonia, or inflammation of the lungs, is also another st ate which the specific catarrhal disease assumes, which it may be supposed to do, bypassing through the larynx into the bronchia; the attack on which is shewn by symptoms of quickened breath- ing, with a short and more sonorous cough : if the inflammation extends, and direct pneumonia is the consequence, unless it be very timely put a stop to, it will carry the dog off— See Pneu- monia, Class I, Sub-Class III ; where the symptoms and treat- ment are detailed. SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 101) The abdominal viscera, but more particularly the intestines, are oftentimes also very violently attacked in distemper. As regards the boivels, they are now and then affected very early in the complaint; but when the catarrhal affection is fully de- veloped, with its usual marks of lassitude, thirst, disinclination for food, shivering, and creeping to the fire, or to some shel- tered corner, with great discharge from the nose and eyes, it is then more usual for the intestines to become the subject of attack. Dogs brought up very hardily, and exposed much to the open air, and to a high and dry atmosphere, may escape diarrhoea altogether ; but of the very young and delicate breeds, and indeed of all such as are more artificially treated, and are confined in cities and towns, the majority have first, diarrhoea, or simple excitement of the muscular contractions of the bowels, which hurries on the contents in liquid and unassimilated dis- charges of the aliment ; and next follows the more serious affec- tion of the intestinal mucous membranes, when the discharges change to a brown or lead-coloured mucus ; and in these cases, when real feces are evacuated, blood usually accompanies them, or it follows them in a few distinct drops. These appearances betoken an ulcerative state of the intestinal canal, and much danger is present : when more mucus and blood is passed than fecal matter, and the fetor is extreme, the case may be considered hopeless. The pustular and yellow appearances of distemper. — Pro- tracted cases of distemper are sometimes accompanied by a pustular eruption, which extends over the surface of the chest and belly, and peels off in scales : but this iutegumental deter- mination seldom affords any relief, and such cases almost in- variably terminate fatally. This state is also sometimes accom- panied with an hepatic affection of a very fatal character, which has been called among sportsmen the yellow disease, from its tinging every part of the surface of the body with a yellow hue ; the urine also is of a deep yellow, the consequence of some morbid translation of the inflammation to the secreting vessels of 110 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. the liver. Mr. Youatt has found this state most frequent in the hound and greyhound; he also has observed it particularly where there is little catarrhal exudation from the nose, which I believe is the case, although I have also seen it accompanied by a profuse discharge ; but it has then been in instances where the disease has run its course, under what I shall next proceed to notice. Tlie virulent and putrid type of distemper, which I have ob- served more common to hot weather than to any other season' although occurring at all times also, is a sequel to either the catarrhal, pneumonic, or hepatic states ; and often itself rages as an epidemic form of the disease, assuming all the characteristics of typhus, gravior, or malignant fever. These cases are accom- panied by great debility, rapid emaciation, and total loss of ap- petite ; the pituitary discharge is great, very foetid and bloody ; bespeaking extensive ulceration of the nasal membranes, which sometimes is such as to occasion haemorrhage from the part : while excoriation of the lips and cheeks follows the contact of the sanies which pours from the eyes, and even the ears also, in some cases: the gums bleed, the tongue is covered with a dark crust, sometimes is ulcerated, and the whole body emits a pecu- liar cadaverous smell. Stools are frequently passing, which re- semble a mixture of mucus, blood, and putrid bile; and the wretched animal trails out a miserable existence, commensurate with the severity of his complaint, his own strength, or the means made use of to combat it: thus in some cases it lasts a few days, and in others it is protracted to two or three weeks even, before he finally sinks. Post-mortem appearances.— These, as may be supposed, vary with the quantum of attack made on individual parts of the body. The morbid anatomy of the head, if we commence with the pituitary membrane, betrays, in every instance, diseased appear- ances, and mostly the whole extent of it, from the nasal fossa? to the frontal sinuses : the aathmoid cells and turbinated cavities are in the first stages very highly injected, in the next suffused with SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. HI pus, and in the last ulcerated; the degrees of which are how- ever not always in the exact ratio of the symptomatic appear- ances • but nevertheless correspond in some degree thereto. Within the cranium, when violent epileptic fits have accom- panied the disease, the membranes of the brain are usually found highly charged witli blood; and when these have continued an unusual length of time, 1 have thought 1 discovered some soften- ing of the cerebral substance itself. Mr. Youatt has found the base of the brain highly injected, and there is often an increase of the serous fluid. The spinal brain presents also phenomena in its morbid anatomy worthy of notice: when the paraplegia, or paralytic weakness of the hinder extremities, has been a marked feature of the complaint, the sheath of the spinal rope has been found more highly vascular, and suffused with an undue quantity of serum. T am also disposed to believe, from my own observations, that the tendency to universal paralysis often draws its origin from a morbid increase of the fluid of the ventricles of the cranial brain. The morbid appearances in the thoracic viscera, in pneumonic cases, are often considerable, from their commencement in the larynx, along the trachea, and throughout its bronchial ramifica- tions, which present inflammatory marks, and muco-purulent secretion in abundance. When pneumonia has been very active, coagulable lymph is sometimes found to be thrown out into the air-cells, congesting the lungs; at others, suppuration takes place, and minute, or in some cases larger, vomicae are found. Less frequently adhesions are met with between the costal and pulmonic pleurae, which occur in protracted cases ; but serous effusion is not uncommon. The heart 1 have found gorged with blood in some of these cases, the pericardium inflamed, and its fluid increased in quantity. The diseased marks of the abdominal viscera vary as follow : the stomach is not often much altered; sometimes, however, the villous surface is somewhat injected, particularly towards the pyloric extremity. The intestines usually bear their full pro- 112 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. portion of morbid characters, being often inflamed throughout, and occasionally are contracted in portions, particularly the ileum ; while the colon is often beset with dark patches, and the rectum with ulcerated spots, when the diarrhoea has been violent and long continued12. The rest of the chylopoietic viscera, in bad cases, partake more or less of the morbid influence, particu- larly the liver, which I have sometimes seen much paler than natural, softer in texture also, and, as it were, macerated: in other cases I have seen it grumous, surcharged with blood, with its biliary duct and sac engorged with an hepatic secretion, as foetid and decomposed as the matter of the stools themselves : in fact, the animal mass throughout, in the malignant cases 1 have noticed, presents a state of complete putrid solution. Prognosis. — To form a decisive opinion of the result of any distempered case, and at almost any period of the complaint, is very difficult ; and I would strongly recommend the veterinary practitioner never to speak confidently with regard to either a fortunate or unfortunate result, however flattering or however adverse the appearances may be. Very young dogs seldom live, puppies of a few weeks old almost never : the difference in these respects, however, between dogs brought up in a state of hardi- hood, and those petted and artificially treated, as well as between those living in the country and those residing in cities, is very great, and should influence the prognostic much. I have already shewn that different varieties have it worse than others, and that some breeds of the same variety possess a particular aptitude to fall under its attacks. The appearance of one fit very early in the complaint is not alarming ; but if it be more advanced, it is truly so ; and when followed up by a second and a third, the 12 Mr. Youatt observes on the state of the intestines, " that if they have been chiefly attacked, we have intense inflammation of the mucous membrane, and, generally speaking, the -small intestines are almost filled with worms. If the dog has gradually wasted away, we have contraction of the whole canal, including even the stomach, and sometimes considerable enlargement of the mesenteric glands." The value of these remarks, in a practical point of view, I need not point out SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. case is nearly hopeless. When the eyes soon after its appear- ance betray a great impatience of light, and look red within, the dog will have it severely, and the extreme quantity of nasal discharge which follows will be apt to wear him down ; if it becomes bloody, it will be still more likely to do so. When the catarrh degenerates into pneumonia, if it is at all intense, it is not often successfully combated. The diarrhoea commonly at- tendant on the complaint is very apt to prove so obstinate as to reduce the animal strength beyond the powers of the constitution to restore, even without the weight of the specific disease attached to it : when therefore the diarrhoea continues to resist medical aid, and is attended with tenesmus and bloody purulent stools, it will generally prove fatal. The breaking out of a pustular eruption, and a yellow tinge pervading the surface of the body, are usually precursors of death. The spasmodic twitchings which sometimes accompany the complaint, if constant and vio- lent, expend the vital energies fast, and usually end fatally : this event may be almost certainly predicted, if the animal loses flesh fast under them ; but let them be as violent as they may, and indeed whatever other unfavourable appearances may occur, if the dog continues to gain flesh, the chances are that he will recover. The treatment of distemper will necessarily vary considerably, according to the mode in which the attack is made, as well as the age, constitution, &c. of the object of it. It is somewhat singular, that while the very best practitioners so often fail in their treatment of the complaint, we seldom meet with a sports- man or breeder of dogs, but who, according to his own account, can readily cure it, " being in possession of what he fondly flatters himself to be an infallible remedy for it." 1 once thought a remedy of my own discovery almost so: but though it re- mains a valuable one, it is far from infallible, and I suspect most of these are much farther from such a character : it hap- pens however with these gentlemen, that, under the exhibition of some medicine (having met with two or three successful cases 114 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. which would perhaps have done well without any thing) such has been afterwards considered as the grand specific. But con- tinued experience leads us to a conclusion, that although many different remedies are useful, according as one or other form of the disease prevails ; yet that there is not, and I believe cannot be, a specific for this protean disorder. As most cases of dis- temper commence by cough or slight defluxion from the nose and eyes, with a failing in the ordinary appetite and spirits, and a gradual losing of flesh, an emetic is the first remedy ; it clears the stomach and bowels, and sympathetically lessens the in- flammatory action going on. Should the pulse or the state of breathing, or the violence of the cough, indicate any determina- tion to the lungs, bleed by all means, to the amount of from three ounces to five or six, according to size, age, &c, particularly if the dog be in good case and moderately strong. The bowels should also be opened by a laxative; but if it is not found ne- cessary to bleed, then substitute a mild purge for the laxative ; unless the dog is either very young, the breed very tender, or there is much emaciation ; in that case merely open the bowels by the laxative. As an emetic, either tartarized antimony (emetic tartar) or calomel may be used ; sometimes one and sometimes the other are to be preferred : when there is any disposition to purging already observed, give the tartar emetic only, in the form and quantity directed under Emetics (p. 84). In other cases, let the puke be made of equal parts of calomel and tartarized an- timony, from half a grain to a grain and a half of each ; or even two grains of each will not be too much for a full grown dog of the largest breeds. Mr. Youatt, with much judgment, prefers this form of vomit, on the grounds that it proves a laxative as well as a puke ; and, as before observed, if there is not already any tendency to looseness, it is the preferable one. The articles used on these occasions by sportsmen, as Turpith mineral and crude antimony, are highly objectionable, on grounds stated in the general directions relative to emetics (p. 85). Salt also SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 115 should only be used for the purpose when the articles already prescribed are not within reach. The early insertion of a seton should depend on circumstances: if that state of impatience of light noticed in the symptoms presents itself, and the pupils look red within, and the cough is harsh, dry, and frequent ; by all means insert one as soon as possible ; but if, on the contrary, the discharge is become purulent and profuse ; and particularly if the dog be not strong, but is losing flesh daily, by no means do so ; the indiscriminate use of setons in distemper is calcu- lated to do much harm. The same may be said oi purgatives, of which 1 would again remark, that while the dog is full, and his inflammatory symptoms run high, two or three moderate purges are proper ; forms of which may be seen at p. 86. Cos- tiveness must, in all cases, be avoided ; but it is best combated by laxatives, except in the very early stages, when, as observed, a purgative is admissible and highly proper ; for unloading the bowels, like unloading the stomach, will tend greatly to lessen irritation, and reduce the inflammatory action of the heart and arteries ; but at the same time that, under these views, they are valuable agents, we must not lose sight of the diarrhoea which is so fatal a symptom of the disease, and which too free a use of them might tend to bring on. These primary depleting means having been carried into effect, proceed with the following : — Antimonial powder 2, 3, or 4 grains Nitrate of potash (nitre) 5, 10, or 15 grains Powdered ipecacuanha 2, 3, or 4 grains. Make into a ball with the minor, medium, or major quantities, according to the size and age of the dog, and give two or three times a day, as the symptoms are more or less urgent ; diminish- ing the quantities if they occasion sickness. When the cough is very distressing, by which pneumonic symptoms may be ap- prehended, add to each dose of these medicines from half a grain to a grain of digitalis (foxglove). Should nothing- new in the symptoms occur, it would be prudent every third or fourth day to repeat the emetic, and to keep the bowels open ii 116 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. also ; but now more than ever avoid active purgation13. Should the disease take on still more active symptoms of pneumonia, or inflammation of the lungs, which will be known by the quick la- borious breathing, the head being elevated, and the dog remain- ing in a sitting position instead of lying down, however fatigued ; then follow the directions given under the head pneumonia, Class I, Sub-Class III. Diarrhoea, or looseness, is one of the most obstinate and fatal accompaniments that attends distemper : it sometimes commences with it, and is then suffered to go unchecked, from a supposition that the complaint may be thus carried off ; but it should never be allowed to go unrestrained for more than two days ; and not even that time, if the disease be at all advanced, or the dog at all emaciated ; otherwise he will be speedily brought so low as to be past recovery. In very young dogs, worms will often greatly aggravate the diarrhoea, and the malign symptoms in general. If any such appearances occur, or any suspicions arise that such is the case, treat as ordered under the head Worms, Class III ; and then proceed with the most effective means of combating the flux, as detailed under Diarrhoea, Class III. The epileptic fits of distemper are the most formidable of all the various types under which the disease rages. It occasion- ally commences by a fit, which should be instantly attacked by an active emetic, and that should be followed by a purgative ; in 13 It was in this stage of the complaint that I used to experience such bene- ficial effects from the distemper remedy first brought forward by me. That it acted, in many cases, as a specific, is most ecu-tain; for without any sensible effect the disease was suddenly arrested, and this so frequently, that I placed unlimited confidence in its general efficacy. I have now no longer any interest in the remedy, or connexion with the vender of it; and I make no doubt that when I had, I was too zealous in my faith in it: but I can with truth assert, that if I now had one hundred dogs in the distemper, I should not th.uk I did them justice if I did not try it on every one. When it is beneficial, the effect is immediate: one dose has often cured ; but when no amendment is observed from two or three consecutive daily doses, I should not recommend any further trial • for it will not benefit that case. When it does good, it acts so promptly, that it occasions surprise, and has been thus lauded to the skies : where it does not, it naturally disappoints, after so much praise, and is then by the other party blackened to the shades. SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. 117 which case it often happens that no more appear14. But when a fit occurs in a more advanced stage of the disease, another will be almost sure to follow, unless such an impression can be made as to cause a counteraction. If a close observation is carried on, the symptoms noted will enable the treatment to take the start of the attack. First give an active emetic, and then follow that up by a brisk purgative. Mr. Youatt recommends a full dose of calo- mel united with opium : insert a seton in the neck, smearing the tape with blistering ointment. Should repeated attacks succeed, give the following to a medium sized dog every two hours, and half the quantity to a small one, in a spoonful of ale: — jEther ■. 1 drachm Tincture of opium half a drachm Camphor 6 grains Spirit of hartshorn 1 drachm. Place the patient in a very warm bath, and retain him there twenty minutes, keeping him also both warm and moist some hours afterwards, by means of wrapping in flannel and placing before a fire : avoid irritation, force nourishment, and endeavour to shorten every fit, by sprinkling cold water in the face, and likewise by soothing language and manner, which have often the happiest effect in lessening the force and duration of the convul- sion. If these means should fortunately succeed, continue to keep the animal quiet both in mind and person, and particularly refrain from allowing active exercise, which is very apt to bring on a recurrence of the fits. See more on this subject in the article Epilepsy, Class II. The chorea of distemper is hardly less to be dreaded than the epilepsy ; for if it is not so immediately fatal, it yet frequently leaves the dog helpless and useless for life. As soon, therefore, as I have observed that one, or even two, violent fits appearing thus early in the complaint, are not always followed by others, nor by any greater severity of symptoms than usual. Is such a fit at all similar to what sometimes precedes eruptive human complaints 1 h2 118 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. there is any appearance of spasmodic twitchings, if the dog be not much emaciated, or the nasal discharge very great, insert a seton ; stimulate the spine every day ; push a cordial tonic plan of medi- cines ; with liberal feeding, and an occasional warm bath. See Chorea, Class II. The debilitating stage of distemper.- -I left off the continuous treatment of the disease, after I had pursued it to its sequel as a phlegmonous affection. Active catarrhal inflammation leaves it when the purulent secretion is fully established ; that is, when pus flows abundantly from the nose and eyes ; after which, what- ever fever remains is of the symptomatic and often hectic type, unless active pneumonic or hepatic affection supervene. It hap- pens, that when I had pursued the treatment of the disease thus far, it was convenient to stop, and introduce such occasional states as are apt to intervene between the first and second stages ; as pneumonia, diarrhoea, epilepsy, chorea, &c. These being no- ticed, I shall now return, and continue the treatment of the true muco-purulent catarrhal affection ; which having been attacked, as directed, by depletion and such other means as tend to combat the acute inflammatory state, must now be as actively pursued by other means ; or a direct asthenic state, or one of diminished vital action, will take place of that where there had been too much. The means hinted at, are the judicious and liberal use of tomes'* and which may with propriety be varied to meet the different complexions that the disease is still likely to assume. One of these is the continued discharge from the nose and eyes, with harassing cough, debility, and emaciation; which state I have i* Among these tonics, none are more ^^^^^0^ most nutritious and tempting W^j^J^gL HX quently, but not in cloying quantities.

I profess not myself to have made use of cantharides or Spanish flies, as a means of checking the inordinate catarrhal discharge ; but I would strongly recommend that a trial should be made of them, when it did not appear to give way to the usual treatment : it may be done after the following manner : — Cantharides, finely powdered 4 grains Gumarabic ditto 1 drachm Opium ditto 1 £rain Chamomile flowers ditto 1 draclmi. Make into twelve, nine, or six balls, and give one night and i6 There is a fashion in our medical opinions, as well as in others. Mr. Youatt doubts the efficacy of gum resins and balsams ; and such is my reli- ance on his judgment, that had he said he was convinced of their inefficacy from his own experience, I should, notwithstanding the benefit I may fancy I have seen attend their use, have even doubted myself; but when he ob- serves, " that they are beginning to get into disrepute in the practice of human medicine," and when he appears to give this as the principal grounds of his objection to them, I must still maintain my opinion of their worth. Neither would their inertness in man necessarily prove them so in the diseases of the dog : we should fail to excite vomition in ourselves by any moderate quantity of calomel; or to excite sleep in the dog by any doseof opium. Buttheseingredients are most active in both these instances to the adverse subjects. I would, there- fore, recommend them to the trial of the practitioner ; and as long as they appear to d'o good, to continue them, but no longer. One thing in their favour is, that for years the compound tincture of Benjamin, known as the Friar's balsam, was a medicine in high repute in some kennels, where nothing beside ever was given. It formed also a nostrum of public sale and estimation, from experi- ence in its efficacy. 120 SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. morning, pushing it to three times a-day, if no amendment takes place. The malignant type of the disease will be found very difficult to contend with ; it is not, however, altogether hopeless, but it can be only successfully combated by prompt and unwearied at- tention. I would recommend the following for trial : — Powdered catechu H drachm Quinine 1 scruple Powdered opium 3 grains Powdered ginger 1 drachm. Mix with conserve of roses into eight, six, or four balls, and give one three times a-day, if the case appears desperate. This form is peculiarly adapted to those cases combined with obsti- nate diarrhoea, in which, while we are checking that by common astringents, we are losing ground by the hectic fever; but by using this we are fulfilling both intentions at the same time. It is also evident that we must vary our curative endeavours to pre- vent the septic or putrid tendency : if, therefore, the above should disagree or seem to fail in arresting the disease, either of the following mixtures may be tried ; beginning with the first, and changing it for the second if it should produce purging, or not sit easy on the stomach, or if benefit does not follow its administra- tion. Under either of these circumstances, the second may also be afterwards changed for the third. Should the price of the quinine be objected to in the prescription for the balls, substitute carbonate of iron, two drachms : if in the liquid mixture, supply its place by two drachms of each of the Peruvian and cascarilla barks : but if humanity be consulted, it will say, try the quinine.

Give of either, one, two, three, or four table spoonfuls, according to the size of the dog, every three or four hours : and if the diarrhoea should be thought any bar to the administration, in- crease the opiate to forty drops with each dose, but continue the medicine, if possible, alone ; if not, alternate it with the reme- dies detailed under Diarrhoea, Class HI. If, however, every remedy only increases the alvine flux, then all but astringents must be discontinued ; for every other means must give place to attempts at restraining this most fatal state, even to the conti- nuance of the antiseptic and astringent plans together, if they be found wholly incompatible with the state of the bowels. Cleanliness is very desirable in every stage of distemper, but in the putrid type it is essentially necessary, as well to the reco- very, as to the comfort of the animal : the free access of pure air is also indispensable, and the removal of every thing likely to har- bour putrid exhalations is highly proper : the litter should be constantly changed, or, if any other bedding be used, it should be washed and dried, or replaced by other. The apartment, kennel, &c, should be cleansed of the putrid effluvia by the use of either the chloride of soda, or lime, according to the directions accompanying those valuable disinfectants ; and which, either of them, particularly the latter, is able to do to admiration : the for- mer is also even more useful in another point of view. I have noticed the phagedenic ulcers which are apt to break out over the face, nose, mouth, &c. : and of the malignant tumours which form in the submaxillary glands, and sometimes in the parotid also ; or, in other words, that break out at the side of the head, and in the angle of the jaws. These take on often a gangrenous appearance, spread over the face, offer a most offensive putrid i-** SPECIFIC CATARRHAL DISEASE, OR DISTEMPER. discharge, and by their irritation greatly aggravate the dangers and sufferings of the animal. These ulcerations, even when extending fast, by being bathed with a solution of the chloride of soda properly diluted, are in most cases brought into a healing state, and in all are deprived of their malignancy, prevented from multiplying, and rendered inoffensive. I have hitherto offered no directions on the subject of the oph- thalmia, which is so liable, in this virulent kind of distemper, to attack either one or both eyes with such an intensity of inflam- mation, that abscess forms on the surface of the cornea, usually about the centre of the pupil ; the ulceration of which sometimes makes its way through the coats, lets out the aqueous humour, and substitutes around its edges fungoid masses : in fact, such apparent havock takes place, that all hope of recovery would seem at an end : yet, surprising as it may seem, this apparently irreparable disorganization is so completely removed, and the true organization so restored, that no traces of the injury remain afterwards. — See Ophthalmia, Class X. Vaccination and inoculation with the matter of distemper have been both practised, one for the -prevention, the other for the mitigation of the disease. Vaccination so performed, is a proof of the gullibility of the public, and readiness to believe wliat is wished, particularly when it comes from a popular source, and where it would be unfashionable to disbelieve. My early expe- riments convinced me of its total inefficacy as a preventive of distemper ; but so positive were the assertions to the contrary, that I spoke diffidently. Dr. Jenner had lent his name to the error, and I make no doubt he believed what he asserted ; but he had not waited the proof. Vaccination, it is now sufficiently ascertained, neither exempts dogs from the distemper, nor does it appear at all to mitigate its severity ; for I have seen a suffi- cient number of dogs which had been vaccinated afterwards die of distemper. Inoculation with the matter of distemper is equally ineffectual in mitigating the complaint, even when it is borrowed INFLAMMATION OF THE AIR-PASSAGES, OR COUGH. 123 from the mildest forms: on the contrary, many dogs, which have taken the disease by inoculation, have had it with peculiar seve- rity, and others have sunk under it. INFLAMMATION OF THE MUCOUS COATS OF THE INTESTINES. Dysentery, as an idiopathic affection in dogs, is very rare ; but an irritation productive of morbid and inordinate mucous dis- charge is produced by various causes. A principal one is the consequence of long-continued diarrhoea common to distemper, as so lately shewn.— See also Diarrhoea, Class III. Another is the result of bilious inflammation.— See Enteritis, Class I, Sub- Class IV. A third cause is the introduction of poisons. — See Class VIII. Super-purgation will bring it on, as noticed with Enteritis and Diarrhoea: the presence of worms will likewise occasion it. — See Worms, Class IV. Inflammation of the Mucous Coats of the Bladder.— See Cystitis, Class I, Sub-Class IV. INFLAMMATION OF THE AIR-PASSAGES, OR COUGH. Idiopathic catarrh will sometimes attack dogs, producing the same symptoms as a common cold usually does with us ; as de- fluxion from the nose and eyes, with cough and slight symptoms of fever. The treatment proper will be an emetic ; mild doses of antimonial powder (from two grains to five), moderate feeding, open bowels, and no exposure to wet or cold. Symptomatic coughs are of several kinds, as that of distem- per, of asthma, of pneumonia or inflamed lungs, and of worms.— See these several affections in the Index. 124 INFLAMMATIONS OF THE DRAIN AND LUNGS. Sub-Class II. INFLAMMATION OF THE BRAIN (PHRENITIS). Symptomatic phrenitis only is found in the canine catalogue ; but of this there are some varieties, dependent principally on the diseases which they are accompaniments to. The epilepsy of dis- temper is an instance of cerebral inflammation, known as well by post-mortem examinations as by the consequences : at the same time it may be urged, that the phrenitic symptoms are seldom of sufficiently long continuance to assure us that the inflammatory state is not conjoined with some other irritations : I shall leave this to the judgment of those who are disposed to study the de- scription of distemper. — Rabies in a few instances produces some decisive violence, and some mental alienation in the dog, as we know by his attack on men and brutes that he has been acquainted with, and also by the morbid appearances which present them- selves after death. — The epilepsy attendant on ivorms, and that which attacks dogs after long confinement, are probably com- pounded of a spasmodic attack on the sensorium and of determi- nation of blood to it : in both cases there are some phrenitic symp- toms occasionally present.— See these several subjects in the body of the work. Sub-Class III. hiflammatory Affections of the Thoracic Viscera. PNEUMONIA, OR INFLAMMATION OF THE LUNGS. Pneumonia is not an unfrequent complaint among dogs, and in some years it rages in an epidemic form, when it destroys num- bers ; in other cases it may be directly traced to the action of cold on the body. I have seen it brought on, in a great number of instances, by the cruel practice of clipping or shearing rough dogs in cold weather. Throwing dogs into the water, and after- wards neglecting to dry them, is also not an uncommon cause : PNEUMONIA, OR INFLAMMATION OP THE LUNGS. l25 shutting a dog out for the night houseless ; in fact, any unusual exposure to cold may occasion it. In many instances it is brought on by distemper. The epidemic pneumonia has usually proved rapid in its progress, and very fatal : at all times also it is to be dreaded, for in most instances it arrives at such a height, before it attracts sufficient notice, as to baffle all attempts at reducing the inflammation. During one of the periods m which it raged in an epidemic form (a warm mild spring), few ot those attacked survived beyond the third day ; about which time most of them were suffocated by the serous effusion poured into the chest. This, though a frequent mode of its termination, in general cases, is not the only fatal one ; for I have seen it also de- stroy by congestion within the substance of the lungs. It yields, however, to a prompt and judicious treatment, sufficiently often to make every effort worth the trial. Inflammation of the lungs shews itself by a quick laborious respiration ; the heart beats m a very rapid but oppressed manner. The head is held up to enable the do- to breathe more freely ; he also prefers sitting to lying down/for the same reasons; which circumstances alone are diag- nostic of the disease. Considerable moisture distils from the nose • which, like the ears and paws, is in general extremely and unnaturally cold. A short quick cough is often present, but not invariably so. The care should be begun by bleeding, and that very largely ; but it must be particularly remembered, that it ought only to be attempted early in the complaint : if it is performed after the se- cond day, the dog commonly dies under the operation. This circumstance should never be forgotten by a practitioner who may happen to be called in, the recollection of which may save him much mortification and disgrace. The first bleeding, if early attempted, may prove useful, provided it is a full and co- pious one. For method and quantity, see Operations. The whole chest should likewise be immediately blistered between the fore legs, and behind the elbows, first removing the hair, and finish- ing by covering the parts with a cloth carefully secured. If blis- •L^° CANINE ASTHMA. tering ointment is not at hand, oil of turpentine with flour of mustard, well rubbed in, and repeated at intervals of two or three hours, will do nearly as well. Give a purgative, throw up a clyster also, and in two hours commence with the following : — Powdered foxglove (digitalis) 12 grains" Tartar emetic 3 grains Nitre 1 drachm. Mix, and divide into six, nine, or twelve powders, or form into balls, and give one every two or three hours : but if there should be much cough present, then substitute the following : — Tincture of foxglove 1 drachm Tartarized antimony (tartar emetic) 3 grains Nitrated potash (nitre) 1 drachm Oxyme] 2 ounces. Give from a tea to a dessert-spoonful of this mixture every two or three hours : should either of these medicines act as a vomit, moderate the dose. It is peculiarly requisite also to keep the dog in a cool temperature, and, provided his skin is screened from the access of cold, it is no matter how cool the air he breathes may be. If amendment should not be apparent in four hours, the bleeding may be repeated, and the blistering likewise. But if, in spite of these renewed applications, the nose and mouth continue intensely cold, the head remains elevated, and the mo- tion of the heart indistinct, a fatal termination may be expected. CANINE ASTHMA. Whatever difference there may be between the human asthma, considered as a spasmodic aflection, aggravated by paroxysms, and that of our present subject, which I consider as more allied to morbid alteration resulting from slow inflammation, yet in its leading symptoms it so nearly resembles that type of the disease called the aerial or dry human asthma, as to allow of the 7 In the administration of digitalis, the pulse should be frequently examined : it is de- sirable that this active remedy should he administered vigorously until the pulse is found to intermit ; alter which time, it should be less actively pursued, for fear of carrying the enervating effect too far. 127 CANINE ASTHMA. application of this popular term. The inhabitants o country owns and villages can for. no just idea of the prevalence and destructive nature of this disease in cities bourhoods, where it is a most common complaint. It derives Us origin from the artificial mode of life forced on pet and fancy do°s, whose close confinement, and over feeding, lead to an ex- traordinary accumulation of fat: and according to the degree m which these predisposing causes have been applied, the disease appears earlier or later in life. In some it comes on at three or four years old: in others, rather less «^*^Jr* not appear until seven or eight: but, sooner or later, most dog , confined in close situations, deprived of exercise, and fed with - heating and luxurious food, become subjected to it, and as cer- tainlv have their lives shortened by it. The disease is usually very insidious in its attack, commencing by a slight cough, which returns at uncertain intervals, and is therefore hardly noticed. Gradually, however, the cough be- comes more frequent and troublesome, and assumes its pecuhar harsh, dry, and sonorous character; and is then often mistakn for a bone in the throat, or for sponge having been designedly .riven. It becomes now excited by every change of temperature, r •, mtn at length, it is almost incessant, ana food, or posmon until, at len ^ even the sleep is interrupted by it. the breatliing affected ; sometimes it is very laborious and painful. The irrita tion of the cough frequently excites nausea and sickness but nothing is brought up except a little frothy mucus from the bron- chial passages, where its presence forms the source of the irrita- tion When the disease is formed, its further progress is quicker or slower as the exciting causes are continued or discon- tinued , the modes also by which it produces its fatal termination are not always the same. In some cases, the irritation of the cough, and the accompany- ing hectic, emaciates and wears down the animal : in others he pulmonary congestion stops respiration, and kills by a sudden Suffocation; or the obstruction the blood meets with m lts pas- CANINE ASTHMA. sage through the heart, occasions accumulation in the head, and convulsive fits are the precursors of death. Now and then a rupture of the heart, or of some large bloodvessel, suddenly de- stroys : but by far the most common termination of the complaint is in dropsy, or serous collections within the chest or belly, or both, but most frequently of the latter. In these cases, the limbs and external parts of the body waste, but the belly increases in its size ; the legs also swell ; the hair stares ; the breathing be- comes very laborious ; and, in the end, suffocation ensues. The morbid appearances, on dissection, are by no means uni- form, but in every instance they are considerable, particularly within the chest. Adhesions sometimes first attract our notice ; next the substance of the lungs, which is occasionally emphyse- matous from ruptured air-cells, and they slightly crepitate under the touch. I have also found a muco-purulent extravasation within the air-cells ; but the appearance most common to them has been, a total change of their natural structure into a granular bluish mass. In some instances, a morbid translation of the external fat was found to have taken place from without inwards ; by which the diaphragm, large vessels, and the interstitial mem- branes of the chest, becoming obstructed and overcharged with adipose substance, the respiratory functions were at length to- tally suspended. The abdominal viscera are very frequently but little affected ; occasionally, however, the mesenteric glands are enlarged, and the liver almost nonsecretory of bile ; and still more frequently the spleen particularly has been found greatly en- larged and diseased. — See Splenitis, Chronic. The care of the disease is always a matter of much uncertainty, and unless it be attempted in the first stages, and before visceral in- jury has procetded too far, the chances of complete recovery are but small ; yet we may often palliate the symptoms. Artificial habits, particularly those of want of air and exercise, with su- perabundance of food, being in nine cases out of ten the cause, it is evident, that without these are in future rigorously and judi- ciously attended to, medicine will avail little. It is unfortu- CANINE ASTHMA. 129 nate, that the accumulation of fat is, in some dogs, so much a disease, that even a very small quantity of food will fatten ; but even that quantity must, however, be still further reduced, so as to produce absorption of the oil ; or it will be in vain to hope for amendment : means to effect which are detailed under the head Feeding. An airy place ought to be allowed the animal to sleep in - but above all, regular and judicious exercise must be given; not violent, but gentle, and long continued. The absorption of the accumulated fat will be materially assisted by a regular ex- hibition of purgatives once or twice a-week. Bleeding now and then gives a temporary relief; and in the incipient stages, when there is any suspicion of inflammatory action going on in the air vessels, it is proper; but in the advanced stages it seldom does much good. Of the various remedial plans I have pursued, none have ap- peared more uniformly beneficial, than a course of emetics, steadily persisted in twice a-week : see Emetics, p. 84. In the intermediate days alteratives were administered, with the occa- sional use of a purgative, provided the dog was strong, fat, and plethoric ; otherwise this was dispensed with : but it should be remembered, that this remedial plan must be uniformly and long continued, to ensure permanent benefit. The alterative is as follows : — Calomel (submuriale of mercury) half a grain Nitre (nitrate of potash) 5 grains Cream of tartar (supertarlrate of potash) 10 grains Antimonial powder 2 grains.— Mix. This may be given either as a powder, or it may be made into a ball with honey ; the dose being repeated once or twice a-day, according to the urgency of the case : the quantities may be also lessened or increased, according to the effect produced ; the recipe is intended for a dog of middling size. On the morning that the emetic is given, the alterative should be omitted ; and where the alterative is repeated night and morning, it will be pru- dent to watch the mouth, that salivation may not unexpectedly |:}<) CANINE ASTHMA. come on. If this should happen, discontinue the medicine tor some days. Where also the calomel has been found to disagree, I have substituted the following alterative with benefit: — Nitre (nitrate of potash) 3 grains Tartar emetic (tartarized antimony) a quarter of a grain Powdered foxglove (digitalis) half a grain. — Mix. This may be given as the other, and alternated with the emetic also, watching the effects of the foxglove, through the medium of the pulse, that they may not be too violent. In some cases of long standing, where the attendant cough has been very harsh, noisy, and distressing, I have added ten, twenty, or thirty drops of tincture of opium (laudanum), or the eighth, sixth, or fourth part of a grain of opium, to each alte- rative with advantage. In other instances, the cough has been best allayed by an evening opiate of double the strength before prescribed. I have, now and then, experienced benefit also from the use of the balsamic gums, which may be all tried, therefore, in obstinate cases. Relief has been obtained likewise from the following, given every morning: — Powdered squill half a grain Gum ammoniacum, powdered 5 grains Balsam Peru 3 grains benzoic acid 1 grain Anisated balsam of sulphur to form a ball. Or, Inspissated juice of the white garden lettuce ... half a drachm Tincture of balsam of Tolu 1 drachm Powdered gum arabic and extract of liquorice 1 ounce each Make into balls, and give one night and morning. The following I have found to mitigate the severity of several cases, and it deserves a trial : — Extract of cicuta half a drachm Extract of hyoscyamus 10 grains Powdered digitalis a scruple Conserve of roses to make 10, 8, or 6 balls, according to the size of the dog ; of which one may be given night and morning ; increasing the INFLAMMATORY AFFECTIONS. J31 dose if it occasions no disturbance in the system. Mr. Youatt lias, I believe, found benefit in asthmatic cases from the exhibition of prussic acid : but the powerful nature of this remedy requires professional assistance when it is administered. Sub-Class IV. Inflammatory Affections of the Abdominal Viscera. INFLAMMATION OF THE STOMACH (GASTRITIS). The stomach is less frequently affected with idiopathic inflam- mation than the bowels ; it is, however, now and then the seat of . primary inflammation, and it often becomes alfected when the bowels are so. In idiopathic gastritis, the sickness is incessant and most distressing ; the thirst is unquenchable, and whatever is taken in, is immediately thrown up again. There is also very great distress in the countenance, but the dog evinces less dis- position to hide himself than in simple bowel affection : the mouth slavers, and is hot and cold by turns. The disease, when violent, is seldom relieved, even by any treatment : but when it does admit of cure, it is done by bleeding early and largely, both by the neck, and by leeches to the region of the stomach. The warm bath should be used, injections should be repeatedly admi- nistered : the chest should be blistered also ; but nothing ought to be given by the mouth. The stomach is likewise liable to inflam- mation from poisonous substances : a very marked and peculiar one results from rabies. The medical treatments of these va- rieties are detailed under the head Poisons. INFLAMMATION OF THE INTESTINES (ENTERITIS). The intestines of dogs are very irritable, and extremely sub- ject to inflammation ; and the phlegmasia? affecting them are of various kinds, according to the operating cause. Distemper is the cause of a variety, that shews itself by a continued diarrhoea. Dogs arc very liable to rheumatism ; but it is no less 13*2 INFLAMMATION OF THE INTESTINES. true than curious, that a dog never has acute, and seldom chronic rheumatism either, that is not accompanied, more or less, with in- flammation of his bowels : this connexion is, however, confined . to the dog alone. In many cases the bowels are the immediate and principal seat of the rheumatism, which is productive of a peculiar enteritis, easily distinguished by those conversant with the diseases of dogs; and further noticed below. Poisons pro- duce a most fatal inflammation in the bowels of dogs ; the effects of which are treated on under the head Poisons. Among the various inflammatory affections, four kinds are pe- culiarly common to the intestines of dogs. The first is that which is brought on by rheumatism, as already explained.- See Rheumatism. Inflammed bowels, from costiveness, forms the second kind, and is a very common occurrence. Dogs will bear costiveness for many days before inflammation comes on; but, when it has commenced, it is not easily removed. This kind is known by the gradual manner in which it attacks, and by its being at first unaccompanied by any very active symptoms. The dog appears dull, dislikes to move, and hides himself ; his belly is hot, and sore also • the constipation is sometimes so complete, that nothing at all comes from him ; at others a few drops of faeces are strained out at every effort, which is apt to make the observer suppose that the doo-is not costive, but, on the contrary, relaxed; he is, therefore, led&to neglect the principal means of relief. In the inflammation arising from costiveness, the sickness of stomach is not at first so distressing ; nor is the dog so extremely anxious for water, as he is when it arises from cold alternating with heat, and its attack is more acute. The obstruction that exists is commonly situated far back in the larger bowels, so that, by introducing the finger into the fundament, a quantity of hardened excrement may frequently be felt This occurs so often, that, whenever costiveness is even suspected, the dog should be examined, by passing the fore finger up the anus. Obstructions may, however, exist in any portion of the in- INFLAMMATION OF THE INTESTINES. 133 testiual track. I have in my possession a portion of jejunum ; in the centre ot which intestine is a cork, that had been brutally forced down the throat. Needles and pins form fatal obstruc- tions sometimes, by getting across the bowels. I have also known a splinter of a chicken bone imbed itself in the sub- stance of ono of the intestines, and form an insurmountable stoppage. Intussusception also now and then occurs, in which one portion of bowel gets folded within another from spasm, and thus forms a complete interruption to the passage of the faeces. Whenever we can ascertain, by the anus, that the obstruction consists of a simple accumulation of hardened excrement within the rectum, it is evident that purging medicines by the mouth can do little good, but may do a great deal of harm, by forcing the impacted contents into a more solid mass. The hardened matter should be carefully broken and separated by the finger, or by a forceps, or the handle of a spoon ; and it may then be brought away piecemeal. If this cannot be effected, or the fascal mass be situated completely without the reach, clysters should be constantly kept up the intestines ; that is, as soon as one comes away another ought to be thrown up. The dog should also be put into a warm bath frequently, which often proves the most effectual means of removing obstinate costive- ness. Medicines by the mouth are not to be neglected, par- ticularly where the obstruction does not exist within the reach of the finger ; on the contrary, a large dose of castor oil may be first tried, which, if it fails to open the bowels, should give place to stronger means. From three to six or eight grains of calomel may be mixed with from half a drachm to one or two drachms of aloes, according to the size and strength of the dog. If the stomach should reject the first dose, add a quarter of a grain of opium to the second : or, a dose of Epsom salts, dis- solved in broth, may be tried. Fortunately for medicine, wc have now a purgative so subtle and' minute, that even a drop put on the tongue proves a powerful laxative. The croton oil \1 134 INFLAMMATION OP THE INTESTINES. acts as powerfully on dogs as on the human subject, and there- fore in these cases should be tried. Repeat the purge, whatever it may be, every three or four hours, until it operates. In the third inflammation (enteritis), or that which comes on spontaneously from irritation, or from the effect of cold, the early symptoms are more acute; great heat, thirst, panting, and restlessness, are apparent even from the first attack. The sto- mach is incessantly sick, and throws off all its contents, mixed oftentimes with biliary matter, and all food is refused, but water is sometimes sought for with anxiety. The belly is ex- tremely hot, and painful to the touch ; the eyes are red, and the mouth and nose are alternately hot and cold. The animal fre- quently lies on his stomach, expresses great anxiety in his countenance, and the pulse is extremely quick but small. En- teritis may be distinguished from spasmodic colic by the extreme tenderness and heat in the bowels, which are not so apparent in the latter complaint. Under these circumstances, the dog should be early and freely bled. From three to six or eight ounces may be taken away, according to the size and strength of the patient. A laxative of castor oil, or of Epsom salts, should be adminis- tered; but unless the bowels are obstinately bound, and have been so for several days, nothing drastic should be given by the mouth, as it would only heighten the inflammatory symptoms. The animal should be bathed in warm water every three or four hours- when that is found too troublesome, from his size or other circumstances, the belly may be rubbed with hot water, or fomented with hot flannels; but one or the other must by no means be omitted. Clysters of castor oil, with mutton broth, should be frequently thrown up, till evacuation is procured ; and when the case is desperate, the belly may also be rubbed with oil of turpentine between the bathings, or covered with a blister- or a mustard poultice may be applied. No food should be given, and cold water should be removed; but the dog may be drenched with mutton broth. In case the vomiting continues INFLAMMATION OP THE INTESTINES. 135 obstinate, with every dose of castor oil, and with every drench of mutton broth, give from ten to twenty drops of laudanum : if the animal becomes paralytic in his lower extremities, if the sickness proves incessant, and the mouth and ears become cold and pale, mortification is at hand. Enteritis, or red colic, is not always accompanied with costiveness; in some there is very little ; and in a few cases the bowels are even lax : but, in the greater number of instances, costiveness to a certain degree is present ; for, even when it did not exist previous to the attack, it is pretty sure to be brought on by it : an effectual laxative is, therefore, premised early in the complaint. If the dog is very delicate, this primary laxative may be castor oil ; but when that is not at hand, or fails in its operation, I have used mild doses of Epsom salts with advantage ; and, in some instances, these have remained on the stomach when castor oil has been rejected. — See Costiveness. Bilious inflammation of the bowels forms the fourth kind of intestinal inflammations ; originating, as I suspect, in some affec- tion of the fiver, which alters its secreting qualities, and makes it, instead of engendering a healthy bile, secrete one of a black noxious kind ; which, as soon as it passes into the bowels, irri- tates and inflames them most highly. This species of enteritis may be distinguished from the other kinds, by the early vomiting of a black or yellow foetid matter, and likewise by the bilious matters evident in the purgings. Poisonous substances will, however, sometimes produce similar appearances in the stools ; caution is therefore requisite in deciding between the two, as the treatment for the one, and that for the other (see Poisons), should be somewhat different. In the inflammations arising from mineral poisons, the vomitings are incessant, and usually frothy and streaked with blood ; the mouth swells, and emits an offensive odour ; and the stools are more bloody and less tinged with dark bile. This inflammation may be distinguished from the bilious by the thirst, which is insatiable under the action of poison. INFLAMMATION OF THE INTESTINES. Bilious inflammation is not a very untractable complaint, when judiciously managed. When the purghigs are already con- siderable, nothing stronger than castor oil, with some opium, should be given ; but this should never be neglected : if even the evacuations are frequent, profuse, and bloody, a mild dose, with forty or fifty drops of laudanum, is proper at first. When the evacuations by the bowels are very trifling, a mild mercurial purge should not be neglected, which I have sometimes found of the greatest service ; as, Submuriate of quicksilver (calomel) 12 grains . Aloes 3 drachms Opium 1 g^in- Make into four, six, or eight balls, according to the size of the dog, and give one every four or five hours till relief is obtained. It will be prudent to give clysters of mutton broth,, and also to force some down the throat : and when the sickness is very ob- stinate, adding to it twenty or thirty drops of laudanum. The warm bath, or fomentations, should be likewise made use of, in case the belly feels hot and tense. When, however, the bilious purging is very great, has existed some time, and in addition to the quantity evacuated, the stools are found to be tinged with blood; here laxatives may be dispensed with, and instead of them, the following should be given : — Powdered calumba 1 drachm Powdered chalk 1 drachm Powdered gum arabic 1 drachm Powdered opium 1 grain. Mix, and divide into three, five, or seven balls, according to the size of the dog, and give one every three or four hours: throw up also starch clysters. The distressing sickness that sometimes accompanies these aggravated cases, and the bloody evacuations likewise, render it very difficult to distinguish them from those that occur from the administration of mineral poisons, without a minute attention to circumstances already detailed. The sick- ness is, however, best relieved in all of them by the powder of INFLAMED LIVElt. 137 calumba, with laudanum, given in moderate but frequent doses, as from ten to fifteen grains of the powder, and from fifteen to twenty-five drops of the opiate. INFLAMED LIVER (HEPATITIS). The hepatic organ in dogs is subject to two inflammations ; one rapid and acute, the other slow and chronic. Acute inflammation of the liver is not a very frequent disease, but I have several times met with it. It may be brought on by cold, and shews itself by dulness, restlessness, panting, and unusual inclination to drink. There is also present, in some cases, frequent sickness ; but it is seldom of that distressing kind which accompanies inflammation of the stomach or bowels. Hepatitis may be distinguished from peripneumony, or inflamed lungs, by the absence of an intense coldness of the nose and mouth; neither is there a watery exudation from them, as in pneumonia; nor is the head held up to facilitate breathing. From inflamed bowels it may be distinguished, by the general symptoms being, although not very unlike, yet less severe, with less prostration of strength ; neither is the region of the belly so hot and tense, although I have observed the right side con- siderably enlarged and tender to the touch in some cases. On the second day of the inflammation, the urine becomes of a deep yellow : the skin appears likewise universally tinged, but the coverings of the eyes and mouth particularly so. This disease is sometimes attended with purging, but much oftener with constipation. When active purging is present, the complaint usually degenerates into the bilious, or fourth kind of inflammation of the bowels. — See Inflamed Bowels. In most instances it proves fatal, unless attended to sufficiently early; and such a termination is at hand when the sickness becomes frequent, when the limbs appear paralytic, and the mouth is pale as well as cold. The proper treatment of hepatitis consists in early and 138 INFLAMED L1VEK. plentiful bleeding; a stimulating or blistering application ap- plied to the belly, particularly towards the right side, with ojjeniug medicines ; and, if circumstances should prevent the application of any stimulant to the region of the liver, the dog should be put into warm water twice or thrice during the day. After the bowels have been well opened, give the following, every three or four hours : — Powdered foxglove 8 grains Antimonial powder 16 grains Nitrated potash (nitre) in powder 1 drachm. Mix, and divide into seven, nine, or twelve powders ; or make into as many balls, according to the size of the dog. If, under this treatment, amendment does not become apparent, repeat the bleeding, and stimulate the skin more actively. Chronic inflammation of the liver arises sometimes sponta- neously, and is idiopathic. In other cases it is brought on by the agency of other affections. Long continued or inveterate mange will tend to produce disease in the liver. In some cases of distemper, also, a dull inflammatory action of the liver occurs, and which is almost always accompanied with a pustular eruption over the belly. The skin is also commonly tinged with a biliary sulfusion ; but the urine is invariably impregnated with much bile ; and both this state, and that more active biliary suffusion, which takes place in some cases of distemper, are known by sportsmen as the yellows. The symptoms are dulness, wasting, a staring coat, and very often a tumour may be felt in the right side of the belly. From the unhealthy appearance of the hair, this disease is often mistaken for worms ; but it may be distin- guished by the want of the voracity of appetite which charac- terizes worms, and also by the general and constant dulness of manner : sometimes, also, it is connected with chronic splenitis, and also with the asthma. The treatment of this disease should be commenced by a mer- curial purge, after which give, night and morning, one of the fol- lowing balls : - INFLAMMATION OF THE SPLEEN. 139 Submuriate of quicksilver (calomel) 20 grains Antimonial powder 30 grains Powdered myrrh 2 drachms Powdered gentian 2 drachms Aloes .-. 2 drachms. Mix with any adhesive matter, and divide into fifteen, twenty, or twenty-five balls, according to the size of the dog. Mercurial ointment 1 ounce Blistering ointment 2 drachms Ointment of yellow wax 1 ounce. Rub into the region of the liver a small portion of this ointment (the size of a nutmeg) once every day. Pursue this treatment some time, carefully watching the mouth, to guard against sud- den and violent salivation. A moderate soreness of the mouth is, however, to be encouraged and kept up : nor have I ever suc- ceeded in removing the complaint without it. INFLAMMATION OF THE SPLEEN (SPLENITIS). Acute inflammation of the spleen, although there is no reason to doubt its existence, I have never marked ; but chronic inflam- mation of this organ I believe by no means uncommon, having myself seen several instances, and I know of one at the present moment in a Newfoundland dog, the property of a friend : at least, from former cases which fell under my observation, I con- clude it so, and am pretty certain I am not deceived. This dog had been subject to great confinement, not being loosened from his chain for weeks together. He was received by my friend with an unthrifty looking coat, but gorged with flesh : the mis- chief, however, was done, and soon began to shew itself; he be- came emaciated, while the left side of the abdomen remains hard and protruded; he husks, and has irregular loose stools. These, in essential particulars, were the symptoms exhibited by the cases 1 have hinted at ; the post-mortem examination of which pre- sented a mass of indurated disorganized matter, very different from the usual vascular spongy structure of the liver. In some 110 RHEUMATISM. asthmatic cases I have found both the liver and spleen diseased in the same way, particularly the latter ; but whether it was a consequence or a cause, I know not. INFLAMED BLADDER (CYSTITIS). This is not a very common complaint among dogs, neverthe- less it now and then occurs : in the year 1810 there was an epi- demic prevalent, in which the bladder was in every instance very much inflamed ; and in many of the cases which occurred it was exclusively so. Cystitis shews itself by a very frequent pulse, great restlessness, and panting : in some instances the urine is evacuated by frequent drops, tinged with blood ; in others there is a total stoppage of it. The belly appears hot, swelled, and is very tender to the touch, particularly between the hind legs. The animal affected should be liberally bled, and have open- ing medicines ; clysters and the warm bath are also to be re- sorted to, and frequently repeated Diuretics are improper, but antimonials, as antimonial powder, or small repeated doses of emetic tartar, are by no means to be neglected. Where the warm bath is not convenient, warm fomentations may be pro- perly substituted. Leeches may also be applied. Sub-Class V. Inflammation of Ligamentous and Aponeurotic Expansions. RHEUMATISM. There is no disease, except distemper and mange, to which dogs are so liable, as to a rheumatic affection of some part or other of the body. Rheumatism presents almost as many varieties in dogs as it does in man; and it has some peculiarities that are observed in the dog only. A very extraordinary one is, that rheumatism never exists in a dog without its affecting the bowels ; RHEUMATISM. 1^1 that is, whatever part of the body becomes rheumatic, either an active rheumatic inflammation will be found to exist in the bowels also, or they will be attacked with a painful torpor : and, in either case, costiveness will be commonly present. The most usual form of this complaint is one which is very similar to the human lumbago. In this case a dog is, in general, seized with a partial or total loss of the use of his hind legs ; his back, particularly about the loins, appears tender and painful to the touch. He screams on being moved; his belly is hot, and very sensible to pressure, and his bowels the seat of much pain. The nose is hot also, the mouth dry, and the pulse considerably increased in fre- quency. Sometimes the paralysis is not confined wholly to the hinder legs, but the fore legs are partly, or completely, paralysed, and helpless also. It seldom attacks the smaller joints, but con- fines itself to the trunk and upper portions of the extremities : neither does it wander, as the human rheumatism, from place to place, but usually remains where it first attacked. A certain prognostic of the termination of this acute type of the complaint is very difficult to form ; for, in some cases, the limbs recover themselves very speedily, in others more slowly ; while, not unfrequently, the paralysis remains through life, and, when confined to the hinder extremities, the animal drags them after him as long as he lives, or gets the habit of carrying them completely from the ground by the strength of his fore quarters. When the paralysis is universal, the chance of perfect recovery is less than when it is partial; though, from this also, dogs do now and then recover by active and judicious medical treatment. It is to be remarked, however, that too often, although the general health may be established, yet some weakness will remain in the loins and extremities : but more particularly it may be regarded as a rule, from which there are few deviations, that, when a dog has once had rheumatism, he will be extremely liable to it again on the access of cold. There is a singular variety of rheumatism that seems to be com- bined with a spasmodic affection, which peculiarly affects the 142 RHEUMATISM. neck, occasioning swelling, stiffness, and extreme tenderness of the part. Sometimes also it troubles, at the same time, one or both fore legs ; but even here, the attack on these distant parts appears to be more symptomatic than idiopathic, for the bowels are always affected, and it happens invariably, that, when they are relieved, the violence of the complaint is always mitigated in the liuibs or neck18. I have not found any one kind of dog to be na- turally more prone to rheumatic affections than another, all seem alike subject to them ; but those become most so that live most artificially, and such as are usually kept warm, but become acci- dentally exposed to wet or cold. The spring produces more in- stances of this disease than any other time of the year, probably from the prevalence of easterly winds at that season1^ The treatment of canine rheumatism should be as follows: — In every instance the bowels must be particularly and promptly attended to ; and in no way does this indication seem better effected than by first placing the animal in warm water, and keeping him there for a quarter of an hour, at the same time rub- bing him well over the affected parts. When taken out, wipe him dry ; wrap him well up in a blanket, and place him within the warmth of a fire : first, however, giving him the following :— Tincture of opium 20 drops Vitriolic sether 30 droPs Castor oil 1 ounce- This quantity is proper for a middling sized dog, and may be increased or diminished in strength at pleasure : should it not be found to operate as a laxative, a clyster should be likewise ad- ministered ; and, in default of that acting also, give the follow- ing ball, increasing or diminishing its size and strength according to circumstances: — '8 See a note on this subject appended to Spasmodic Colic, Class II. 19 Dogs, particularly such as are closely domesticated, become remarkably open to atmospheric impressions. Any sudden change of weather, especially from a dry to a moist state, may be seen in the depressed countenance ami listless maunerof many of them. Many others cannot be exposed to an easterlj wind, for a quarter of an hour ev en, without becoming affected with rheumatism.

Make into a ball with lard or butter, which give ; and, if neces- sary, repeat every four hours till the bowels are perfectly open ; and keep them gently so by mild aperients for several days after, or until amendment takes place.

Soap liniment (opodeldoc) two parts. Mix. The warm bath should be repeated at intervals of one or two days, according to the quickness or slowness of the amendment ; moderate feeding only should be allowed. Sometimes food is al- together refused ; more frequently the animal is as willing to eat as°at other times ; and it is not uncommon, in some of these cases, from a morbid sympathy of the stomach and bowels, for him to be more than usually voracious. When the paralysis occa- sioned by rheumatism continues to deprive the limbs of their mobility, I have experienced some good effect from electricity, in others from mercurial frictions, and in some cases from blisters along the spine : where the hinder Umbs only have been para- lytic, a very large pitch plaister, applied over the whole loins, reaching to the tail, as well as covering the upper parts of the thighs, and worn for two months, or even longer, has been of great service. I have experienced benefit also from the cold bath ; but the warm bath, though a most admirable remedy dur- ing tie rheumatic attack, I have never found to give any relief to the future paralysis. Finally, when all these have altogether failed, I would advise a trial of the tonic plan recommended for Chorea; and as a last resource acupuncturation might be tried, which see among the Operations. 144 CLASS II. Spasmodic Diseases. EPILEPSY. Epileptic fits are of frequeut occurrence in dogs, and may, like those in ourselves, be considered both idiopathic and symp- tomatic ; or, in otber words, they appear constitutional at some times, the result probably of particular organization, and at others are caused by accidental irritations, as worms, metastasis in distemper, &c. Blows on the head have made dogs subject to occasional attacks of epilepsy ; and the nervous susceptibility of some is such, that any unusual excitement, whether of joy or fear, will bring it on. Sporting dogs, particularly such as are what is called very high bred, in which the mental irritability is artificially increased, are often the subjects of it when ranging in the pursuit of game, and particularly such as have been pre- viously confined much ; from the unprepared state of the brain to bear the unusual quantity of blood determined to it. In some dogs, the mere plethora of the constitution, or the fat accumu- lated, are sufficient to produce an attack ; and such, without other excitement, if made to travel an unaccustomed distance be- hind a horse or carriage, particularly at a quick pace, fall into a fif, and from doing it unobserved are frequently lost. Fear will often occasion an epileptic attack in young dogs, or in dogs of any age, if previously debilitated by illness. Worms are a very common cause of epilepsy in young dogs ; and teething in pup- pies. Distemper also ushers in its attack sometimes by a fit of this kind, in which case it is not an unfavourable symptom ; on the contrary, when epileptic fits occur during the progress of the disease, they commonly destroy the patient. The epilepsy of distemper may be readily distinguished from the other varieties by the attendant symptoms of that disease being present, as well EPILEPSY. as by the full detail of its peculiarities of attack under that head, (p. 116.) The treatment of epilepsy must be preceded by an inquiry into its probable cause. Where close confinement and accumulation of much flesh may be supposed the principal agents, let the dog be bled, purged, moderately fed, and regularly but not violently exercised. Where a natural irritability, as in the high-bred sporting varieties, appears the cause of the excitability, it should be moderated by accustoming them to a more uniform and full supply of the objects occasioning it, with a habit of regular ex- ercise, whether wanted for sporting purposes or not : thus, for a valuable setter belonging to a gentleman, which seldom went to the field without an epileptic attack, I recommended his being taken into a country more plentifully supplied with game than his neighbourhood afforded ; the consequence of which was, that though, for a few days after his removal, he had fits more fre- quently than ever, yet they gradually lessened, and at length wholly left him. Where repletion and want of condition appear the principal causes, lower the system by bleeding, purging, and occasional emetics, as detailed under the General Treatment oj Dogs (p. 66). A seton is also a valuable remedy, and when- ever fits have become habitual, insert one, and keep it open some months. An epileptic fit can often be stopped by cold water thrown over the head and body ; and whenever a fit has occurred, the dog should have a brisk purge, as costiveness is not an unfrequent cause ; and this is the more prudent, because should it arise from any other source, the treatment is equally proper. Such an oc- currence ought also to be followed by an examination of the stools, and by looking for other signs of worms, which are often the occasion of it. See Worms, Class III. The epilepsy of bitches ivhen suckling' is of a different kind to that I have been treating of, being wholly asthenic, and conse- quent to the attempt of the mother to furnish a greater number of 140 EPILEPSY. young than the constitutional strength of the animal is equal to20. It is found principally among fancy and highly-petted dogs, whose irritability of temperament is thus increased by their artificial habits : occasionally, however, it occurs with others less confined and pampered, where the owners are anxious to save several of a litter, or are forgetful to supply the necessary extra nutriment. The appearance of these fits is made at uncertain periods of lac- tation, as the constitution begins to sympathize extremely, sooner or later, with the unnatural call made on it. The mother may go on well for weeks even ; suddenly, however, she will be seized with convulsions, which will follow each other with rapidity, and carry her off : the cause of which is seldom suspected, but it almost always arises from debility thus brought on. The mother should always, therefore, be allowed to suckle as many puppies only as her constitutional powers are equal to ; but to specify the precise number is totally impossible, as some can bring up five or six with more ease than others can rear three. Strong healthy bitches, that have before brought up young, may rear four or five : delicate ones are sufficiently burthened with three ; many can only bear two. The treatment is to be commenced by an immediate removal of 2<> Without consideration, some might say, how then do dogs in a state of na- ture survive these hazards? to which may be replied, Let nature alone, and she will provide for her own children ; interfere with her, and she leaves the onus with you. In a state of nature, the canina; breed but once in the year, and never have more, I believe, than five or six at a birth. Cultivation and do- mestication have so altered their habits (see p. 41), that our dogs breed three times in two years, and some five times in three years, and have s.x, eight, and occasionally many more whelps at a birth. We have also decreased then- powers of supplying these extra wants, by the very same means we have in- creased their generative powers; by making them artificial instead of natural animals. I have had many occasions of proving, that this artificiaJ cultivation weakens their resources under disease, and under other acc.dental circum- stances, as breeding, &c. Nature thus punishes the deviations from her esta- blished rules; and as this frequent gestation and unusual rearing of extra nu- merous progeny is of man's own work, he must oppose art to art, by destrouno as many of the young as may be supposed beyond the powers oi the mother to rear- and also by giving her extra support, to nourish the remainder. EPILEPSY. 147 the puppies : one or two may be put to her for half an hour, morning- and evening ; or, if she is distressed at their loss, and lias much milk left, one may remain with her ; but, unless the ma- jority are taken away, she cannot be saved. As an internal re- medy, employ the following : — Sulphuric a?ther 1 drachm Tincture of opium (laudanum) 1 drachm Strong ale 2 ounces.— Mix. Give from a dessert to two table-spoonfuls of this mixture, ac- cording to the size and strength of the patient, repeating the dose every two or three hours. Force down also some nutritious mat- ter, solid or liquid, as diet ; and, as soon as the animal will eat, let the food be of the very best kind, and in sufficient quantities. But let the warm bath be resorted to before all. The true idiopathic epilepsy, or that which becomes habitual without a known or accidental cause (or even that which is occa- sioned from accidental causes), should it resist the preventive means already directed, must be combated by antispasmodics and tonics : commence the treatment, however, by the following, where the dog is strong, and in full condition : if otherwise, pro- ceed with the next recipe : — Calomel (submuriale of quicksilver) 8 grains Carbonate of iron half a drachm Extract of hemlock (cicula) I scruple. Mix with conserve of roses, palm oil, &c. &c. ; sufficient to form twelve, nine, or six balls, of which give one every morning. Should these not mitigate the attacks, try the following : — Nitrate of silver (lunar caustic), finely powdered... 2 grains Spiders' web, called cobweb 5 grains Conserve of roses sufficient for balls. Make into nine, twelve, or fifteen balls, according to the size of the dog ; of which give one every morning. CHOREA, SPASM, CONVULSION, AND PARALYSIS. Chorea, known in the human subject as St. Vitus's dance, is a peculiar modification, or compound of spasm and paralysis. Wc K 148 CHOREA, SPASM, CONVULSION, AND PARALYSIS. have sufficient reasons for considering the whole of these as aris- ing from certain morbid affections or states of the brain ; though po°st-mortem examinations have often failed to detect any struc- tural alteration there ; and when such do occur, some might be led to attribute them to the force of the symptoms ; or, in other words, as an effect rather than a cause. Chorea is sometimes general, as is seen in some states of distemper, when the animal as umver- sally affected with muscular spasmodic contractxons from head to foot, as well sleeping as waking : every limb is alternately flexed and straightened, as though the poor brute was in constant and fatiguing exercise; while his cries and moans bespeak his suiter- inas, and he dies, worn out by the irritation and exhaustion pro- duced, earlier or later, as his own strength or the degree of the disease operate for or against him. Chorea is, however, more frequently partial, and these con- vulsive twitchings are confined sometimes to the head and neck, which are bowed continually ; occasionally only apart of the lace is so convulsed ; in others the fore quarters are principally affected, being drawn down with distressing regularity. Now and then it is in the hinder quarters, and sometimes in one limb only ; but wherever it exists it seldom affords any respite. In this state a dog will continue, particularly when it is the consequence of dis- temper, for a longer or shorter period; and oftentimes it remains throu-h life, rendering the objects of it useless as sporting dogs, cuard°s, &c. Chorea may be the consequence of other irri- tations beside distemper, as worms, injuries received on the head and debilitating diseases ; but the distemper is the most frequent cause. . The treatment is usually of the tonic kind, although m the more early stages it may not be imprudent to act on a supposition that some revulsive means, directed to the sensorium, might be useful In such case, a seton might be applied, or a blister to the back ot the head ; or the spine might be stimulated ; but it is rare, when the disease has continued some time, that these means are at- tended with benefit. We may expect more from tonic remedies, CHOREA, SPASM, CONVULSION, AND PARALYSIS. 149 as liberal feeding, pure air, the cold bath, frictions, with the following : — Nitrate of silver, ground very fine 3 grains Carbonate of iron, powdered 2 dracluns Gentian ditto 3 dracluns Conserve of roses sufficient to make twelve, nine, or six balls, of which, give one every night ; and if the medicine is well borne on the stomach, give it both night and morning, It is the practice at the Royal Veterinary School of Lyons, to treat dogs in this com- plaint with the gum assafoetida, dissolved in vinegar, both by the mouth and by clysters ; and the accounts are very favourable with regard to it, if it is sufficiently long continued, but most so in those cases where there is neither paralysis nor marasmus. Other tonic formulae may also be used, in which the sulphate of iron, sulphate of zinc, quinine, very minute doses of the strychnine, as one-eighth of a grain, may any of them enter. It is not, however, improbable that the disease will baffle every attempt at cure. Spasm differs from chorea, principally in its being an irregular motion rather of the internal than the external muscular fibre ; when very violent and diffused, it degenerates into what is popularly un- derstood by convulsion, in which way it is that partial spasm, parti- cularly chorea, ends : thus the twitchings which affect the limbs in distemper, when, instead of lessening they increase daily, usually end by one universal convulsive attack, which destroys the animal. Dogs are very subject to spasm from a variety of occasional causes ; it is also the usual accompaniment of several idiopathic diseases. Rheumatism produces spasmodic affections of the bowels, and often likewise of the neck, fore extremities, &c. In rabies, spasmodic contractions are very common. Spasmodic colic is not unfrequent in dogs; it also affects the bowels of puppies in a very particu- lar manner sometimes. — See Colic. Cramp, which is the familiar term among sportsmen for spasm, occasionally seizes the limbs suddenly, attacking first one and k 2 150 CHOREA, SPASM, CONVULSION, AND PARALYSIS, then the other. Tetanus, or locked jaw, is also a spasmodic affection. The best external antispasmodics are the warm bath, with close confinement in flannel afterwards. In some cases, an ex- traordinary degree of warmth, in whatever way applied, has proved useful, with volatile embrocations applied to the pained parts. Internally the following may be given :— JEther 20 10 60 Tincture of opium (laudanum) 20 to 60 drops Camphor 3 to 6 grains. Mix these together, and give in a table-spoonful of ale or of wine and water, according to the urgency of the symptoms. No fear need be apprehended from an over-dose of opium; for in these cases analogy between the human and brute should not be allowed to guide the exhibition; a dog will bear five times the quantity of opium that a human person could. When spasm affects the bowels, sometimes much benefit arises from clysters with a drachm of laudanum in each. See Colic, Spasmodic- Warm bathing, as before noticed, should never be omitted as a remedy in general spasm; but, in some cases of long-continued spasmodic affection, more purely paralytic, as in the twitching* arising from distemper, tonic remedies, with cold bathing, are more proper. Extensive bleeding has very often relieved some occasional spasms; and other cases of longer standing have been benefitted by the treatment detailed under the head Ept- ^ Paralysis is probably the consequence of a diminution of sen- sorial excitement, by which a total or partial loss of motive power is experienced in certain parts of the body : in extreme cases it m*y l general; it is usually, however, local. Rabies is a very common cause of paralysis of the jaws and muscles of he throat, loins, and hinder extremities: sometimes an universal paralytic weakness is also diffused over the frame in rabid dogs Distem- per very commonly is attended with some paralysis of the hinder TETANUS, OR LOCKED JAW. 151 parts, sometimes of the head and fore legs, and now and then it is mildly but universally diffused. A frequent source of paralysis is rheumatism, which see (p. 140). The treatment must vary according to the cause producing the affection. General warmth, with stimulating applications to the immediate parts, is proper for most early cases : when long con- tinued, the cold bath proves often most efficacious ; but still, dur- ing the intervening time, the body should be kept warm. As a general remedy in rheumatic paralysis, an extensive pitch plaister deserves an immediate trial. Blisters and electricity are some- times useful. For local injuries, a seton opposite the injured part often proves beneficial. Electricity is worthy of attention. Acu- puncturation, both in chorea and in paralysis, is deserving of trial. The process is detailed with Operations, Class XII. TETANUS, OR LOCKED JAW. It is remarkable, that although dogs are very subject to vari- ous spasmodic affections, yet to that called tetanus, or locked-jaw, they are so little so, that I never met with more than three cases of it among many thousands of diseased dogs. These are, how- ever, sufficient to establish the susceptibility of the dog to the complaint. Two of these cases were idiopathic, one being appa- rently occasioned by exposure to cold air all night : in the other, the cause was obscure. The third was of that kind called symp- tomatic, and arose from external injury done to one of the feet. In each of these cases the convulsive spasm was extreme, and the rigidity universal but not intense. In one case the jaw was only partially locked. Both warm and cold bathings were tried; large doses of opium and camphor were given by the mouth, and thrown up in clysters also. The spine of one was blistered. Stimulating frictions were applied to all, but in neither case with any salutary effect. 152 SPASMODIC COLIC. Among the spasmodic affections of dogs, those attacking the bowels are particularly deserving of notice, from their singularity, importance, and variety. In all violent colics there is probably some spasmodic constriction ; and thus the colic of worms ; that resulting from acrid poisons, particularly of lead ; or from consti- pation ; or from bilious inflammation, invariably present appear- ances of some spasmodic action on the canal. There is also the spasmodic colic of rheumatism (p. 140), which is of so peculiar a nature as hardly to allow us to conclude whether it be a cause or an effect, by the circumstance that no relief from the rheumatic; or spasmodic symptoms, which affect the head, neck, or limbs, can be obtained, until the bowels are relieved of their contents. The true spasmodic colic in dogs is violent in its symptoms, obstinate in character, and very often fatal iu termination. I was apt formerly to attribute these cases to the presence of worms, and I am still inclined to think that these animals, par- ticularly the tape worm, will now and then occasion similar symptoms; but the generality of cases may be considered as arising from an irritation sni generis. Certain appearances also might beget a suspicion, that the head, iu these instances, was the sole seat of the complaint : but however the head may be con- nected with the disease, the nervous affection is spent on the intestinal tissues; and the bowels are the ostensible seat of the morbid attack1, which is of a peculiar spasmodic nature, and commonly attended with a slight degree of inflammation. • If reference is made to the article Distemper, and if the physiological hints there thrown out on the connexions between the brain, as the scat of sensorial and motive power, be looked over, it will be an introduction to what is (o follow: which I would premise by observing, that although in a work at first intended as a popular vade mecum on a new branch of the an medendi, I was somewhat obliged to fix the description of a disease where we could best identify it by its consequences, yet it docs not follow, that as we proceed wc may not be allowed to enlarge our sphere of reasoning, and direct our inquiries rather beyond the plain matter of fact. Under this view, with our SPASMODIC COLIC. 153 The symptoms are dulness, loss of appetite ; the nose is hot, but the forehead particularly so ; with some panting, and much restlessness. In some cases, there are appearances of acute occasional pain ; in others, there is seen but little ; but in all there is a particular stupor, and a very remarkable inclination to ran round in a circle, and that always in the same direction. The sight seems affected, and sometimes the senses are wholly lost, at others, although the stupor is considerable, yet the facul- ties are not totally obscured. In some cases, paralysis comes on, and the head becomes drawn to one side; and I have always observed it to incline to the same side that, while capable of moving, the dog turned upon. The limbs also participate in these extreme cases, and become contracted likewise. It is necessary to observe, that lead received into the stomach will also produce all these symptoms occasionally. The duration of the complaint is various. It sometimes de- stroys in a few days, while some cases linger two or even three weeks ; but eventually five out of every six attacked with it, die. On dissection, slight marks only of inflammation usually appear ; and now and then intussusception is present ; but in all, portions of the bowels in a contracted state are met with, extended knowledge of the phenomena of nervous distribution, and the inti- mate connexion of all diseases of increased action (and spasm may be but a morbid modification of such action) with the brain, as so admirably entered into by Dr. Clutterbuck, are we warranted in indulging in a suspicion that this particular variety of colic, and that also described with rheumatism, as a rheumatic spasm of the neck and bowels, may be rather symptoms of idiopathic affectio&'of the brain than of the parts we detect the consequences in? In the affection under our immediate consideration, the symptoms give strong indication of a direct attack on the sensorium itself; but in pursuing the disease, either as to the consequence of a fortunate termination, which seems always the result of applications to the intestinal track, and also the absence of morbid phenomena of any extent in post-mortem examinations of the brain, the probabilities seem to incline to the idiopathic seat being within the bowels themselves; always bearing in mind, that the first reason is the most cogent of the two : for the absence of cerebral marks of disease is no proof of morbid action not having gone on. The matter is worthy of all the observation, and all the consideration of the veterinarian. 154 SPASMODIC COLIC. while other portions again seem larger than usual, and are flabby and unnaturally relaxed, as though they had lost all their tone by the disease. The most attentive dissection of the head, in these cases, has never detected any morbid appearances there, except, in one or two instances, a slight increase of vascularity. The affection of it, therefore, during the progress of the com- plaint, must be considered as purely symptomatic, and as not at all referrible to any specific affection of the sensorium itself; and, although the head feels hot during the disease, the eyes are flushed, and great pain appears in it, from the pressure that is always made by the animal against the hand, when it is held to it ; and the sense of pleasure that is manifested when the fore- head is rubbed; yet direct medical applications to the head, as fomentations, blisters, and leeches, have always failed to give any relief; while the only remedies that have succeeded have been such as were applied immediately to the bowels. The treatment I have found most successful consisted in early and active evacuations, as „ ., half an ounce Castor oil Oil of peppermint * d™P Tincture of opium 20 dr°P8' If this should fail to relieve the bowels in half an hour, repeat it ; and in an hour or two from this second exhibition, if no stool has been procured, and real costiveness had been previously present, oive aloes half a drachm to a drachm, or a drachm and a hall, according to the size of the dog. Aperient clysters must also be thrown up, and often repeated, until the bowels are suffi- ciently evacuated. During the course of that part of the treat- ment directed to opening of the bowels, the spasmodic construc- tions can be attended to at the same time also, by batlnng in water sufficiently warm. Frictions with some spirituous mix- ture to the belly, as gin, or olive oil two parts and oil ol tur- pentine one part. When the bowels are emptied, then give the following : — DIARRHCEA, OR PROFUSE PURGING. 155 yEther half a drachm to a drachm Tincture of opium ditto Camphor 3 to 6 grains Castor oil 3 to 5 drachms. I add castor oil to the antispasmodic mixture, from a confidence in its being a valuable agent in quieting the irritation, as well as in overcoming the obstruction ; but if diarrhoea have already come on, then it should be omitted. Anodyne clysters must also be thrown up after the bowels have been opened ; the warm bath, likewise, and stimulating frictions should be continued, at short intervals, until the case is hopeless or mitigated. The occasional and epidemic spasmodic colic of puppies, though essentially the same with that we have described, de- serves a separate notice, because it sometimes rages in an epidemial form ; and also because it appears more directly an intestinal attack; the head not being affected either with vertigo or stupor : its spasms take place at intervals, occasioning loud cries while they last. The treatment, however active and judi- cious, is seldom successful ; but that which has seemed the most efficacious has been mercurial purgatives ; as calomel one gram, aloes a scruple, opium a quarter of a grain : make into a ball, and give every two hours, until the bowels are open. A young dog of some strength and size should have a double dose ; a Newfoundland, a treble one. Warm bath, stimulating frictions, and clysters, aie equally proper here as in the preceding. CLASS III.

Docs arc subject, under various morbid affections, to loose- ness of bowels : it is one of the most common and obstinate 156 DIARRHOEA, OR PROFUSE PURGING. symptoms in distemper ; and in that complaint the evacuations are of a very variable quantity, colour, and consistence ; some- times glairy, at others thin and watery ; often frothy, pale, and in small quantity; now lead-coloured, and then bloody. In bilious purging they are yellow or black; and when worms exist, they change frequently, but usually have some glair, and are often frothy also. When diarrhoea continues for many days, the rectum becomes inflamed and slightly ulcerated within the fundament, by which a constant irritation and tenesmus are kept up ; and the poor animal, feeling as though he wanted to evacuate, is continually trying to bring something away. On observing this, persons are frequently led ip to error ; for, under a supposition that there exists actual costiveness at the time, they give purging medicines, which greatly aggravate the complaint, and frequently destroy the dog. When the diarrhoea is con- siderable, there is always violent thirst, and cold water is sought after with great eagerness ; but which increases the evil, and, therefore, should be removed, and broth or rice-water should be substituted in its room. When diarrhoea has con- tinued many days, particularly in the malignant distemper, it often takes on something of a dysenteric appearance, from the mucous surface of the intestines becoming inflamed, and throwing off their mucous secretion in great quantities with every motion. The cure of diarrhoea must depend on the light in which we are led to consider it ; whether as a disease of itself, or as merely the symptom of some other existing disease. For instance, a bilious purging, which comes on suddenly with violent vomiting, is best removed by evacuants to carry off the vitiated bile from the bowels. In the looseness occasioned by worms also, purga- tives or other vermifuges should be made use of to remove the cause, and not astringents, which would merely apply to the effect. But when diarrhoea appears an idiopathic affection, that is, as a diseased action of the bowels themselves, and also when it is produced by distemper, it should in either case be imme- diately checked, or it may produce such weakness and emacia- DIARRHOEA, OR PROFUSE PURGING. 157 tion as will destroy the dog. In the distemper it is particularly necessary to check the looseness very early ; for when it is con- tinued beyond the third or fourth day, its invariable effect is to destroy the appetite, after which, of course, the weakness in- creases in a double degree. The remedies employed, when diarrhoea is a primary com- plaint, are generally either of an absorbent or an astringent na- ture : but a long experience enables me to state, that the loose- nesses or scourings of dogs are best combated by a proper mix- ture of both these. In the purging which accompanies distem- per, however, the disease frequently proves very obstinate, and even baffles every endeavour to remove it. Suet, boiled in milk, has been long a favourite domestic remedy, and in slight cases is equal to the cure. Alum-whey has also proved useful, but more frequently as an injection, than by the mouth. Great bene- fit has also been experienced from an infusion of the inner rind of the barberry, particularly when the evacuations have been glairy and mucus-like. In cases where there has been an appear- ance of much bile in the stools, and the dog has been strong, I have found it prudent sometimes to premise an emetic of ipeca- cuanha, after which either of the following recipes may be used with advantage. In point of efficacy they are to be ranked, ac- cording to my experience, in the order in which they stand. No. 1. Powdered opium 5 grains Powdered catechu 2 dracluns Powdered gum arabic 2 dracluns Prepared chalk 2 drachms Powdered ginger half a drachm.

Mix with six ounces of boiled starch, and give a dessert or a table-spoonful every four, six, or eight hours. In very obstinate cases try the following : — No. 4. Powdered resin 3 drachms Powdered opium 6 grains Powdered chalk 2 drachms Powdered alum 1 drachm. Conserve ot roses sufficient for balls : Form into four, six, or eight balls, according to the size of the dog, of which give one every two or three hours. It is necessary to be aware that the action of astringents is varied and uncertain. In one case one remedy only will prove successful, and in another a very different one will alone do good: But in the looseness that accompanies distemper, it may be ob- served as a general rule, that absorbent astringents succeed best. In some very desperate cases of diarrhoea, when all other means have failed, I have derived great benefit from astringent clysters ; and this so frequently, that I would, in all such instances, strongly recommend their adoption. From the benefit that is frequently experienced from their use ; and from the tenesmus, and appear- ance of the stools, in which a drop or two of blood is squeezed out at the last expulsive effort, we might judge that the rectum, or sometimes the colon, is, in many cases, the principal seat of the complaint, and post-mortem examinations shew this to be ac- tually the case. Astringent clysters may be composed of alum whey, winch is nothing more than milk curdled with alum. Suet, boiled in milk, is also an excellent clyster for the purpose. Boiled starch is likewise a valuable astringent clyster, and, perhaps, is the very best that can be used, if the powder No. 1 be added to it. In diarrhoea, it is of the greatest consequence that the strength should be supported by liberal but judicious feeding ; and it must COSTIVENESS. 159 not be forgotten that, when the appetite ceases, starch, with gravy, should be forced down in small quantities, bat often. The animals affected with this complaint should be kept very quiet and warm, both which parts of the treatment must be care- fully attended to. In some instances I have witnessed the good effects of a daily warm bath. I have also observed, where the diarrhoea of distemper has existed in a dog who had been before closely confined, that removing him into a more free and pure at- mosphere has tended greatly to check the disease. COSTIVENESS. Dogs, as carnivorous animals, have naturally a dry constipated habit, that is greatly increased, in many cases, by the bones they receive as food, which, when given in great quantities, ag- gravate the natural torpor of their bowels, particularly where they cannot relieve themselves by a natural evacuant in the dog- grass. Costiveness is productive of numerous evils ; it increases the disposition to mange and other diseased secretions. It also pro- duces indigestion, encourages worms, makes the breath foetid, and blackens the teeth: but it is principally to be avoided from the danger, that the contents of the bowels may accumulate and bring on inflammation. -See Inflamed Bowels. Whenever a dog has been costive three days, and one or two moderate ape- rients have failed of opening the bowels, it is not prudent to push the means of relief farther by more violent purgatives; for this would be apt to hurry the contents of the intestinal canal into one mass, whose resistance being too great for the bowels to over- come, inflammation follows. Mild aperients may be continued, but clysters are principally to be depended upon.— See Clysters. In such cases, the introduction of the clyster pipe will often de- tect a hardened mass of excrement. If the action of the pipe, or the operation of the liquid, should not break this down ; it is ab- solutely necessary to introduce the finger, or, in a very small dog, AU" INTESTINAL WORMS. a lesser apparatus, and mechanically to divide the mass and bring it away. The recurrence of costiveness is best prevented by ve- getable food and exercise : but when vegetable food disagrees, or is obstinately refused, boiled liver often proves a good means of counteracting the complaint. — See Feeding. Colic, Inflammatory. — See Class I, Sub-Class IV. Colic, Spasmodic. — See Class II. INTESTINAL WORMS. Of those worms which appear indigenous to the intestines of the dog, the tarda, or tape worm, from its flat figure, is the most prejudicial, and the most difficult to remove. I have known four or five hundred joints (each a distinct animal) passed by a dog, whose united length would encircle his body many times. Some- times they become coiled up into a ball, which thus forms an impenetrable obstruction within the intestines, and destroys the dog. The teres, or long cylindrical worms, resembling earthworms in figure, but of a whitish colour, are the most common to dogs ; and, when existing in great numbers, particularly in puppies and young ones, sometimes prove fatal by the convulsions they occasion. In distemper they greatly aggravate the symptoms ; so much so, that to destroy them, frequently cures the dog. The natural situation of these worms is within the intestines, but they sometimes crawl from them into the stomach, and are then brought up by the sickness they occasion. The ascarides, or small thread-worms, likewise occasionally infest dogs, residing principally within the rectum. They pro- duce an intolerable itching in the parts behind, to relieve which, those troubled with them are seen continually drawing the funda- INTESTINAL WORMS. 1G1 ment along the ground. Except by the irritation occasioned, which may weaken when it is excessive, they do not appear to do much internal injury. The constitution of some dogs appears particularly favourable to the generation of worms ; for, destroy them as often as you will, they soon return again. Puppies, dur- ing every stage of their growth, are very liable to them : in many, the increase of the body appears checked by their ra- vages. The presence of worms, when they exist in considerable num- bers, is easily detected; for such a dog has usually a slight cough, his coat stares, he eats voraciously, yet seldom fattens : his evacuations prove also a most unequivocal symptom ; for they are, in such cases, peculiarly irregular, being at one time loose and slimy, and at another more hard and dry than natural. The belly likewise is often tense and enlarged. When very young dogs have worms, the first that pass are seldom noticed, for they seem to affect the health but Uttle ; but gradually, as they increase, purging becomes more frequent ; and the animal, though lively, becomes emaciated ; his appetite is often irregu- lar, his nose hot and dry, and his breath foetid. The growth likewise appears stationary, and in this way it is very common for him to continue, till a fit or two carries him off, or he dies tabid. In adult dogs, worms are less fatal, though, from the ob- structions they form, they sometimes kill them Hkewise ; and they always occasion a rough unhealthy coat, with a hot nose and foetid breath ; and in both the young and the full grown, they occasionally produce epileptic fits. It does not follow, be- cause no worms are seen to pass away, that one who exhibits the other symptoms of them has none ; neither, when they are not seen, does it follow even that none pass ; for, if they remain long in the intestines after they are dead, they become digested like other animal matter. The treatment of worm cases in dogs has been like that of the human, and the remedies employed have been intended cither to destroy the worms within the body, or otherwise to 162 INTESTINAL WOKMS. drive tkem mechanically, as it were, out of the bowels by active purgatives : but, as these latter means were violent (for, without the very mucus of the bowels, as well as the faeces, were ex- pelled, no benefit was derived from them), so the remedy, in many instances, became worse than the disease. Many sub- stances have, therefore, been tried, iu hopes of destroying these animals within the body ; and it is evident, that any thing that could certainly do this would be most important, as it would obviate the necessity of having recourse to the violent purgative means heretofore employed. For this purpose, substances which present small spiculi, or points, have been found the best adapted for the destruction of worms, by abrading their external or internal surfaces, and that without, in the slightest degree, injuring the patient. Among huntsmen and gamekeepers, glass, very finely powdered, is a very favourite remedy. An old man of this description, in Buck- inghamshire, was famed for worm killing in dogs, and his only means used was glass finely powdered, and given as a ball. Mr. Youatt also recommends the same. If this should be ob- jected to, from what I believe to be a groundless fear, that it is dangerous, try the following : — Cowhage (dolichos pruriens, Linn.) half a draclim Tin filings or iron, made with a very fine file.... 4 drachms. Form into four, six, or eight balls, and give one every morning ; after which, a mercurial purgative will be proper. I have oc- casionally succeeded, in very obstinate worm cases, by moderate daily doses of Epsom salts. Ascarides are best destroyed by soap or aloetic clysters. The tape-worm is not unfrequently removed by mercurial purges ; but a still more certain remedy for this noxious guest is such doses of oil of turpentine as a dog could take safely, remembering that dogs bear very little of it : to some, however, it proves much less hurtful than to others. A small clog might be tried with half a drachm given night and morning, mixed with the yolk of an egg, for a few days : a PILES— FISTULA IN THE ANUS. 163 larger two scruples, and the largest a drachm, beginning always with a very small dose, and increasing it, if it produce no disturbance. PILES. Dogs are very subject to piles, but the symptoms by which the complaint shews itself are by no means known as such, although they are not very dissimilar to the human haemorrhoids. The complaint is brought on by confinement, heat, and healing food; and shews itself by a sore red protruded anus, which the dog aggravates by dragging it on the floor : it is likewise fre- quently the effect of costiveness. The tenesmus occasioned by diarrhoea may readily be mistaken for piles, from the anus ap- pearing red and sore : and it is evident that in such a case, to effect a cure the looseness must be restrained, and the sore anus may be anointed with the ointment directed below, omitting the tar. The habitual piles will be greatly relieved by the use of the following ointment : — Sugar of lead 6 grains Tar half a drachm Elder ointment, or fine lard 3 drachms. Mix, and anoint the fundament with it two or three times a-day. To correct the habit towards the disease, feed moderately on cooling food, exercise sufficiently, and, as long as the disposition to it is considerable, give daily one of the following powders : — Nitrated potash (nitre), powdered ... half a drachm Milk of sulphur 3 drachms. Divide into nine, twelve, or fifteen doses. FISTULA IN THE ANUS. Tins is not a very uncommon complaint in dogs, and is de- rived from constitutional aptitude, as a carnivorous animal, to the formation of fseees so hard, and so difficult of evacuation, as often to abrade the rectum, and produce inflammation and ulcera- L 104 DROPSY. tion : this sometimes has ended in leaving a fistulous opening in the cellular substance which surrounds it, and which usually makes its way outwards. A mere external fistula, or external opening by the side of the anus, not communicating with the rectum, may, in general, be cured by any mild stimulant daily inserted to the bottom : but an internal one, by which is meant a fistulous communication between the rectum and the external opening, which buries itself into the cellular tissues around it, will usually require an operation for its cure. A probe-pointed bistoury must be passed up the fistulous orifice, while a finger of the unemployed hand is introduced within the rectum, which will guide the section to be made. By this means the fistulous cavity formed in the cellular substance, and that existing in the rectum, are to be laid into one, by dividing it down, from its utmost extent to the verge of the anus. When a true fistulous opening exists, but not communicating with the intestine (which is very seldom the case in the dog), the point of the bistoury, when it has been passed up to the limits of the external wound, must be forced through the intestine, and then carried downward. It must, however, be remarked, that when this latter fistula is the consequence of external violence, it should not be so treated until fully tried by stimulants ; to which, as before observed, it will commonly yield without an operation. The section being made, introduce lint dipped in the compound tincture of benjamin between the edges of the wound, and into the sinuous hollow ; keeping the body during the cure gently open. CLASS IV. Morbid Collections of Fluid. DROPSY (HYDROPS) Is by no means uncommon in canine pathology. Dogs are most subject to ascites, or dropsy of the belly. In the next DROPSY. 165 degree of frequency they have hydrothorax, or dropsy of the chest ; less frequently they have encysted dropsy ; and, least of all, are they subject to anasarca, or dropsy of the skin, unless when accompanied by ascites. The former is usually the con- sequence of some other chronic affection, as asthma, tabies, &c. : neglected mange has also produced it, but more frequently it is Mowed by ascites. Acute hydrothorax commonly succeeds to active inflammation of the lungs; in which cases, about the third day from the pneumonic attack, the water begins to be formed within the cavity of the chest, and increases so as to suffocate the animal in a few hours.— See Inflamed Lungs. Dropsy of the chest may be known to exist by the extreme uneasiness the dog shews when he lies down, and by his attempts, under such circumstances, to elevate Ins head. The chest will also appear full and swollen, and the water within may be gene- rally heard on motion. The beating of the heart will likewise afford a decided characteristic of the complaint; for the hand, placed on one side of the chest, will be affected with a kind of thrill, very different from the usual sensation presented by the beating of the heart of a healthy dog. The cure may be attempted by the means recommended for ventral dropsy; but I have hitherto found the disease fatal in every acute case, without exception. In both the chronic and acute it may not be amiss to try the effects of paracentesis, or the operation of letting out the dropsical accumulation, which will afford the only chance: in the chronic hydrothorax I have pro- longed life, even some weeks, by this means ; but as the cause which had operated in producing it had injured the constitution beyond repair, so I never established a perfect cure. The operation of paracentesis thoracis, or puncturing the chest, though not quite so simple as letting off water from the belly, yet is neither a complex nor a dangerous one, if only a moderate portion of caution be used. Make an opening through the integuments, by means of a lancet, near the anterior edge'of the eighth or ninth rib, about the termination of the bony portion l2 !()(> DROPSY OF THE BELLY. of the rib into its cartilaginous addition, which will be readily detected by the touch. Previous to making the opening, draw the skin a little to one side, to ensure a ready closing of the ca- vity against the entrance of the external air. Carefully introduce a small trochar, rather upward and backward, so far only as just to penetrate the pleura, which will be known by a gush of fluid : now withdraw the trochar, and push the canula a bttle forward, to evacuate the fluid effectually. If both cavities are found drop- sical, open the other side also ; which done, close the opening or openings with adhesive plaister, and bandage over it. DROPSY OF THE BELLY (ASCITES). This is not an uncommon disease with dogs ; and a prodigious quantity of water is sometimes accumulated within the abdomen. The causes of the disease are various. Among the most common are long-continued asthma ; a diseased state of either the liver or spleen ; tabies mesentericus ; and old, virulent, and wholly neg- lected skin affections, particularly mange. The serous accumu- lation is sometimes slow, at others very rapid ; and the symptoms that precede the attack are, of course, as various as the causes that produce it. In some cases the forerunner is a harsh cough ; in other instances nothing is observed but a ravenous appetite2; and the dog, although he may eat an additional quantity, yet he will waste in flesh. Gradually, however, his belly begins to swell, and grows round, hard, and shining. The breathing becomes quick and laborious, and he lies down with difficulty ; he drinks much : and, though in the early stages he may eat heartily, yet, as the disease advances, his appetite fails, and, sooner or later, he becomes suffocated from the impediment to the free action of the lungs. Dropsy of the belly may be distinguished from/ntf, by the par- ticular tumour that the belly forms, which, in dropsy, hangs pen- s In these cases it is more than probable that the mesenteric glands have taken on disease : when dropsy is the consequence of diseased liver, the appe- tite is not usually so ravenous. DROPSY OP THE BELL V. 107 dulous, while, at the same time, the back bone sticks up, and the hips appear prominent through the skin : the hair stares also, and the feel of the coat is peculiarly harsh. It may be distin- guished from pregnancy by the teats, which always enlarge as gestation advances ; neither has the impregnated belly, however full, that tight tense feel, nor the shining appearance, observed in dropsy : there may be also foetal inequalities distinguished in it ; and, when pregnancy is at all advanced, the young may be felt to move. The most unequivocal mode, however, of detecting the presence of water is by the touch. ]f the right hand be laid on one side of the belly, and the other side is gently struck with the left, an undulating motion will be perceived, exactly similar to what would be felt by placing one hand on a bladder of water, and striking it with the other. Treatment of ascites, or dropsy of the belly. — . The medical treatment, in these cases, is seldom attended with success, be- cause the complaint itself is seldom primary, but the consequence of some other destructive chronic affection, which has probably already committed fatal ravages on the constitution. Now and then, however, I have seen attacks of ascites apparently not pre- ceded by either of these affections ; and in these I have sometimes succeeded in obtaining an evacuation of the water, and in pre- venting a recurrence of it also. But such instances are so in- ferior in point of number to the others, that, in general terms, ventral dropsy may be described as a most fatal disease. Paracentesis abdominis, or tapping, holds out the most rational hope. I have repeatedly tapped dogs ; from some of which I have drawn off many quarts of fluid, sometimes of a gelatinous consistence, at others simply serous and thin. In some cases I have repeated the operation two or three times, whieh has tend- ed to prolong life; but eventually the same fate awaited the greater number. The operation of tapping a dog does not differ in any respect from the same process in the human. A trochar is the most proper instrument for the purpose, but the operation may be performed by a lancet, and the puncture should be made 1GS DROPSY OF THE BELLY. directly in the linea alba, or median line of the belly, about raid- way between the pubis and umbilicus, or navel ; by which no important vessel, nor any thickness of muscle, will be endangered. If a trochar is used, make the puncture at once ; but take care that it does no more than penetrate the cavity. Should a lancet be employed, do the same ; but in this case, a quill having both ends perforate should form a canula after the puncture. The evacuation of all the water may be proceeded on at once without fear ; the animal will express no uneasiness nor faintness ; but will conduct himself as though nothing had happened. A bandage moderately tight should be applied round the belly, and retained there many days, or even weeks, to assist the absorbents by its pressure. I have also tried various other means for the evacuation of the water, but they have seldom afforded any permanent benefit. In a very few instances only, diuretics have produced a salutary and durable effect : of which class I have found the digitalis, or foxglove, the very best. Now and then, however, other medi- caments of this kind have succeeded when this has failed. I shall, therefore, detail such recipes as appear best suited to the case, observing that, with regard to the foxglove, it is most certain in its effect as a diuretic, as well in the canine as the human species, when it neither occasions sickness nor purging. The dose should, therefore, be always so regulated as to avoid these effects : — No. 1.— Powdered foxglove 12 Srajns Antimonial powder 15 Sralns Nitrated potash (nitre) 1 drachm. Mix, and divide into nine, twelve, or fifteen parcels, one of which give night and morning. No. 2.— Powdered foxglove 9 Srilins Powdered squills 12 &rn"ls Supertartrate of potash (cream of tartar) 2 drachms. Mix, divide, and give as No. 1. No.3.-Oxymelof squills 1 0 >"'<•'' Infusion of tobacco (as directed) half an ounce Spirits of nitrous Kther (meet spirit of nil,;) ... half an ounce Tincture of opium halfa drachni Infusion of chamomile 8 ounces. DROPSY OP THE SKIN. 169 Mix, and give from two tea-spoonfuls, to a large table-spoonful, night and morning. The tobacco infusion may be made by pouring two ounces of boiling water on a drachm of tobacco. I have, in some instances, combined calomel with the other reme- dies to the amount of half a grain, or a grain, night and morning ; and this apparently withbenefit. I have also tried the effect of strong mercurial purges twice a week, in cases where diuretic medicines failed of relieving, Friction and the warm bath have been also used, but without apparent advantage4. In the few dropsies where- in diuretics succeeded, active stomachic tonics followed their use : in some instances they accompanied them. Nor should these be omitted where tapping is employed, as the only means likely to prevent the belly from again filling. DROPSY OF THE SKIN (ANASARCA). As before observed, this complaint very seldom occurs, unless as an accompaniment of ascites. I have, however, now and then seen it, and, in most of the cases, it was in old dogs who had laboured under some previous debility. In such instances, when any remaining stamina affords a chance for recovery, the treat- ment recommended for dropsy of the belly may be resorted to : very small punctures may also be made in the distended skin. Hydrocephalus internus, or dropsy of the brain, can hardly be said to belong to the canine nosology ; but on turning to the description of epilepsy, it will be seen, that morbid anatomy has shewn a diseased increase of the serous fluid of the cerebral cavity to be no uncommon circumstance. Hydrorachis, or dropsy of the spine, by reference to former articles, will be found to exist without its congenital character, and that, perhaps, more often than we at present suppose. Encysted DROrsv. — An accumulation either of serum, or of 4 In one case, one part of oil of turpentine, with two parts of olive oil, nibbed into the belly night and morning, appeared to excite absorption; but it must be noticed, that the turpentine was also given at the same time in- ternally, to the amount of thirty drops twice a-day. 170 DROPSY OF THE SKIN. a fatty or gelatinous matter, within a particular sac, is thus called. The dropsy of the ovaria is by much the most frequent of this kind, and, to a certain extent, is very common in bitches ; but it is in these general cases, more an accumulation of fat than serosity. I have, however, seen instances of true ovarial dropsy of the hydatid kind, which all terminated fatally, although they proved very slow in their progress : they are to be detected by the swelling being less universally diffused, and having obscure undulation. The tumours may also be often traced to have com- menced on one side only ; sometimes it continues to occupy more of one side than the other : the enlargement, probably, first appeared in the loins, and did not extend downwards until it gravitated there by its weight. The treatment of these cases must be the same with that of ascites ; but I never saw but one which did terminate favourably, and in that I discharged the fluid contents by a trochar effectually : in others, this mode failed, and even hastened the death. Hydatids, independent of the ovaries, likewise now and then form a species of dropsy in other parts. I have seen them in the liver, the lungs, the spleen, and the brain. Dropsy of the eye-ball is sometimes seen either idiopathic or traumatic. — See Diseases of the Eyes. CLASS V. Diseases of Glands. CANINE SCIRRHUS AND CANCER. Scirrhus in the human subject is considered as the primary stage of cancer ; but dogs, though very subject to tumefactions which present much of the character of human scirrhus, and which degenerate into obstinate and increasing ulceration, yet do not often present an equal likeness of the human cancer. The canine scirrhus, likewise, is not wholly like that of our own ; CANCER. 171 for, instead of exhibiting various strata of morbid matter, the innermost of which is the most condensed, there are seen, in the canine tumours of this kind, appearances more resembling a collection of glands, or of firm hydatids; each of which exhibits on a section of it, a distinct diseased process. Scirrhous indura- tions appear to arise from the same causes that tend to the pro- duction of mange ; namely, a superabundance of the secretions of some parts, the effect of a general fulness of habit striving to relieve itself. These tumours are, therefore, most frequent among dogs which are hotly kept, over-fed, and suffer much confine- ment. Scirrhous mamma. — The lactiferous glands are very usually the seat of scirrhous tumours, particularly among those bitches who have not been allowed to breed ; especially when plethoric, and when their exertions and their feeding bear no proportion to each other. The origin of these tumours may be very fre- cpaently dated from an inflammation in the mammae, from retained milk when the pups have died ; or from the coagulating of that milk which forms, by sympathy, about the period a bitch would have pupped, provided she had been allowed to breed. A small nucleus, or kernel, not larger often than a pea, is first felt within the gland, which sometimes increases fast ; at others it enlarges very slowly, appearing to give little uneasiness, until its weight makes it prove troublesome. If the tumour is not dispersed in this state, sooner or later, one or more small shining vesicles form on its surface, which ulcerating, ooze out an ichor or glairy fluid, but seldom produce a healthy pus. The first opening often heals up, but others follow ; and, in the end, two or three, or more, appear at the same time, which, breaking in different parts, are soon licked into one sore by the animal ; and although the ulceration does not spread rapidly, or put on the virulence of human carcinomatous ulcerations, it seldom heals afterwards, but, at length, wears down the animal by the continued discharge. While the tumour is externally whole, and is throughout indurated, without hydatid-like vesicles, it 172 CANCER. may be, now and then, dispersed by the frequent application of active discutients, as Muriate of ammonia (crude sal ammoniac.)... I ounce Acetic acid (vinegar) 4 ounces. Bathe with this three or four times a-day. Brandy and water, or vinegar, or common salt and water, are also good discutients. In some cases, the repeated application of leeches will be found beneficial. In others, the means recommended for the cure of bronchocele may be tried, with the addition of sarsaparilla. During the attempts at discussing these tumours, a repetition of the causes producing them should be carefully avoided, such as a sympathetic repletion of the teats from coagulated milk, and the obstruction to its passing off, by depriving them too early of their young ; but particularly by avoiding whatever tends to produce repletion, as confinement, over-feeding, &c. &c. As, however, all means at dispersing these tumours are very apt to fail, and ulceration almost invariably occurs, it follows that extirpation, or the cutting of them out, is the remedy usually necessary to be resorted to for their complete removal. This operation may be safely performed, in every instance, with only common precautions : out of innumerable cases on which 1 have operated I never lost one. It is, however, in general, prudent to let the tumour increase till, by its weight, it becomes pendulous, and detached from the abdominal muscles, when it may be dissected out without any danger of opening the peri- toneum, or of wounding large arterial branches. In dividing the integuments, care should be taken to destroy but little of their surface, except such as may be actually diseased ; for, by detaching the tumour neatly from its coverings by a careful dissection, and by leaving some sound integument, the wound much sooner closes, and the cicatrix which follows is necessarily smaller, and less corrugated. As the excision proceeds, the bloodvessels should be taken up ; and, when the tumour is re- moved, two or three stitches should be introduced into the opposite edges of the skin to bring them together ; by which the BRONCHOCELE. 173 cure will be considerably expedited. These stitches, however, ulcerate out in three or four days ; but they usually have, by this time, performed their office, and the remaining wound will require only common dressing, with the addition of bandages sufficient to prevent the dog from interrupting the healing by her nose and tongue. Wens and scirrhous tumours are not confined to the teats only ; nor are dogs without them, as well as bitches. There is scarcely a part of the body but what I have seen these wen-like enlargements on ; the treatment of which in nowise differs from the plans already laid down. BRONCHOCELE, OR GOITRE. Bronchocele is a steatomatous swelling of the glands of the throat, apparently of the thyroid, and is a very common com- plaint among dogs. Pugs, barbets, and French pointers, are peculiarly liable to it. In the human species, this disease is most common to the inhabitants of mountainous countries. But in dogs it does not appear endemial, and is more confined to some particular breeds. Other dogs, as terriers, spaniels, &c, sometimes, however, have it ; but it is not frequent in these, and in the larger tribes it is very seldom seen. The swelling comes on generally while very young, and continues to enlarge to a certain size ; after which it usually remains stationary, seldom increasing to such a degree as to prove fatal. It is, however, troublesome, and in some measure hurtful, from the pressure it occasions on the surrounding parts. The treatment is not difficult, nor usually unsuccessful, when early adopted. Friction is of much benefit. Internally, one of the following balls should be given every day ; in bad cases, twice a day : — Burnt sponge 1 drachin Nitrated potash (nitre) half a drachm. Make into six, nine, or twelve balls, according to size, &c. 174 SCIRRHOUS TESTICLES— CANCER. Mild mercurial ointment half an ounce Blistering ointment half an ounce. Mix, and rub the swellings once a-day with a portion equal to a hazel nut, or a walnut, according to the size of the dog ; first clipping away the hair, and, after the application, wrapping up the neck with a bandage, to prevent the ointment from being rubbed off. During the use of this application, the mouth should be examined now and then, to guard against the sudden attack of salivation. Should this treatment fail to remove the tumour, recourse may be had to the new remedy Iodine, which has proved so successful in the human goitre, and in a few cases of goitre in the dog also it has been exhibited with some success ; but its extreme potency of action requires that it should be given only under the immediate superintendance of one well acquainted with its qualities. SCIRRHOUS TESTICLES. The testicles in dogs are sometimes also the seat of scirrhous induration. In such cases, one or both of these glands become hard, painful, and rather tender, with a shining fulness of the scrotum : occasionally ulceration takes place, but it is rare. If the tumour does not readily give way to the application of the active discutients that are recommended for the mammary scirrhi of bitches, try the effect of a regular administration of burnt sponge, as recommended under bronchocele. In some cases, mercurial frictions have succeeded; but, in default of these, proceed, without delay, to castrate, to prevent the disease from extending up the spermatic chord. — See Castration, CANCER. I have already stated that the virulence of the human car- cinomatous ulceration, is commonly wanting in Avhat I call the canine cancer; for though spreading and incurable, as regards its locality, yet it seldom extends beyond the precincts of the gland it is seated in; and if it ever makes further inroads, they CANCER. 175 are slow, and not marked with constitutional derangement for a long time : are seldom, if ever, translated to the lungs ; and do not appear to give those lancinating pains felt by the human victim. Still there are characters in it, which make the term applicable ; and now and then also, more virulent features mark its progress. I have likewise occasionally seen the ulcerous affection, called canker in the ear, when of long standing, take on the true carcinomatous character, and extend rapidly over the muscles of the face, till, having destroyed one eye, and commenced its at- tack on the throat and tongue, the animal was destroyed. I have also seen cancer in its most malignant form in cats ; first attack- ing the mammas or teats, and then spreading over the abdominal muscles and surrounding parts. Cancers of the vaginee and uterus are by no means uncommon, and are sometimes occasioned by the foolish practice of exciting premature oestrum by stimulating injections ; but more frequently by a brutality often exercised towards dogs, of dashing them with cold water, or of forcibly separating them during copula- tion. Cancer sometimes attacks the labiae, at others the inner surface of the vulva, and sometimes extends to the uterus ; but, in either case, it presents a fungous excrescence, of a deep red or of a more livid colour, with ulcerated uneven edges, while bloody ichor constantly distils from the surface. In the very few cases where I have seen animals suffered to live to the extent of the complaint, the fatal termination has been slow but certain : gradually, the morbid secretion of the part united with the irrita- tion ; but, principally, the former has worn down the animal. When cancerous ulcerations have taken place in these or in other parts, I have seldom succeeded in restoring a healthy action, or of promoting a cure, otherwise than by excision. Now and then, however, I have experienced benefit from the use of the bruised leaves of the hemlock, as a poultice daily ; with balls composed of one, two, or three grains of extract of hemlock (ac- cording to the size and strength of the dog), and ten, fifteen, or. twenty grains of burnt sponge, in each ; repeated once or twice 176 TABIES MESENTERICUS. a-day, as the health would bear them. Extirpation is however the most eligible remedy, and may be, in most cases, practised with safety by an experienced surgeon or veterinarian. When cancer is purely glandular, from its circumscribed form, no dif- ficulty will be found in detaching the whole morbid substance ; but when it has attacked the muscular, cellular, or superficial parts, as the face, parieties of the abdomen, scrotum, vulva, or uterus, then the utmost caution is requisite to remove every dis- eased portion. It must also be taken into the account, that al- though, in the canine cancer, ulceration does not often re-appear in the immediate part, when the operation has been judiciously performed, yet, when the constitution has long been affected with this ulcerative action, it is very apt to shew itself in some neighbouring part soon after. TABIES MESENTERICUS. A tabid state of young dogs has already been touched on in the rearing of puppies : it is born with some, and acquired by others. Some breeds, particularly pugs and terriers, are singu- larly liable to it ; dependent on the attempts that have been made to breed them very small, or to a particular "fancy," i. e., form or colour. In these cases, it appears hereditary, and is disse- minated through the whole stock : it may also be produced after birth by close confinement, bad air, and the want of a due supply of healthy milk, or other nutritious food when that is dried up. The objects of it present a stinted growth, bowed legs, with the elbows directed outwards, coat staring, the belly pendulous, and a countenance of peculiar sharpness and saga- city. When it proves fatal, the mesenteric glands are found diseased, enlarged, and impervious to the transmission of chyle : morbid marks likewise are not unfrequent in the liver : the intes- tines also are often filled with worms, but which are frequently more a consequence than a cause ; sometimes, however, they appear to occasion the disease. DISEASES OF BONES. 177 The treatment, when worms are the cause, should commence by destroying' them ; when otherwise, act according to circum- stances : if the milk of the mother be suspected, change it, or give cow's milk boiled with flour and sugar, with minced meat. Use the cold bath ; allow wholesome air and exercise ; use fric- tions to the body, give a mild mercurial aperient every third day, and on the intermediate ones a tonic ball of carbonate of iron, gum myrrh, and gentian. This disease is sometimes com- bined with rickets, which see in the next class. CLASS VI. Diseases of Bones. RICKETS (RACHITIS). Rickets is very like to tabies, in all its causes, and also in some of its, appearances and effects : it is common to the same breeds, and is both occasional and hereditary. It is occasional when it meets with the circumstances of confinement, bad air, filth, and unwholesome food, or the milk of an unhealthy mother. Many whelps are born with the predisposition, among the fancy breeds in the confined parts of great cities and large towns, particularly pugs and the smaller sort of bull dogs : there is also a breed of wry-legged terriers which without doubt originated in ricketty specimens which were afterwards culti- vated for particular purposes, principally rabbit-hunting. The affection often appears soon after birth ; and shews itself by the slow development of the body, except in the head, belly, and joints, all of which enlarge at the expense of the rest of the parts: particularly it attacks all the joints of the extremities; these swell into protuberances, probably from a sympathy in the constitution to make up, by bulk, what the bones want in pon- derosity, but which is not effected ; for, deprived of their earthy solidifying principles, they yield to the superincumbent weight, and the cylindrical ones particularly become crooked. Cleanli- 178 DECAYED AND TARTARED TEETH. ness, good air, free exercise, and wholesome food, will com- monly prevent it in the future breeds of such dogs as have shewn a disposition to it. As a cure, an invigorating diet added to these, with the occasional use of tonic bitters if the appetite fail s, or the digestion should appear defective, will answer the in- tention. Unconsolidated fracture. — The phosphate of lime, or osseous matter which should form the callus of bones, in some cases is never deposited between their fractured ends, and a mere cartilaginous union remains. It is evident this is, in fact, a disease of the same nature, and probably originates in the same causes with rachitis ; and if our instances were sufficiently multiplied, we should find this proved by fact. — For the treat- ment, see Fractures and Dislocations. DECAYED AND TARTARED TEETH. Sportsmen and persons living in the country, who are habi- tuated only to healthy dogs, will smile at such a head line ; but were they in London, or other large cities and towns, where dogs are petted and immured in hot apartments night and day ; where also they are gorged with the richest food, and are not exercised but in a carriage ; and withal are probably descended from a long lineage of parentage equally unnaturally treated ; they would see sufficient of these effects of an imperfect diges- tion, to make them aware that this article is perfectly in place ; and the remarks which follow are in unison with the general intention of these pages, to let nothing pass unnoticed which a long and critical attention to the habits and diseases of these animals renders necessary to be guarded against and remedied. In the dogs I have described, nothing is more common to find than carious teeth, insufferably foetid ; others displaced, prevent- ing mastication ; or an immense accumulation of tartar which covers them, erodes the gums, and makes the animal insufferably offensive. The veterinarian will often be called on to remedy these evils : the decayed teeth he must remove, and the displaced URINARY CALCULI. 175) ones also; the tartaric deposit he must likewise completely scale off with proper dental instruments ; for the accumulation is not only most unpleasant to tl?^ owners, but injurious to the dogs, by its septic tendency, and its invariably ending in the destruction of the teeth. The ulcerations are best removed by touching them with a mixture of a proper strength made from the solution of the chloride of soda with water : by the use of this, these ulcers will quickly heal ; and the continuance of it will do much to remove the remaining fcetor, and stop the turther deposit of tartar, particularly if coupled with a corresponding improvement in the general treatment of the animal. ANCHYLOSIS AND EXOSTOSIS. Stiff joints, splents, and spavins, occasionally enter the kennel as well as the stable ; and when not too far advanced in the ossifying process, may sometimes be checked by a blister re- peatedly applied, at each application covering the part well up, and carefully muzzling the dog. — See Blistering, Class XII. CLASS VII. Calcular Concretions. There is hardly any cavity of the body of the dog in which calcareous matter has not been found ; as in the brain, in most of the glands, and in the intestines, where, occasionally, considerable masses have been detected, some of which had formed themselves a sac by distention of the intestinal coats. A case of this kind appears in No. 36 of The Veterinarian, where a calculus was found encysted within the parietes of the ileum. URINARY CALCULI. These are not very common, but however do exist ; and nearly the whole pelvis of the kidney in one case was found to be occupied by a calculus ; much pain had hecn suffered, much emaciation was M 180 VESICAL CALCULI, Oil STONE IN THE BLADDER, present, and whenever he urined, blood and mucus were passed with the fluid. VESICAL CALCULI, OR STONE IN THE BLADDER. This is a more common complaint than the last : I have myself met with several instances; and I have not less than forty or fifty calculi by me, which I took from * Newfoundland dog, after his death, occasioned by the obstruction to the passage of the urine by means of these stones. Death had already happened before I was called in, or probably relief might have been afforded by an operation; but the symptoms had been, constant difficulty in his urinary evacuations, until one of the number of calculi had entered the urethra, and had so blocked up the urinary flow, that mortification ensued. When a small calculus obstructs the urethra, and can be felt, it may be attempted to be forced forwards through the urethra to the point of the penis, from whence it may be extracted by a pair of forceps : it it can- not be so moved, it may be cut down upon and removed with safety But when one or more stones are withm the bladder, we must attempt lithotomy, after having fully satisfied ourselves of their existence there by the introduction of the sound : to do which it must be remembered that the urethra of the dog, m passino- from the bladder, proceeds nearly in a direct bne back- wards ; and then, making an acute angle, it passes again for- wards to the bladder. It must be, therefore, evident that, when it becomes necessary tointroduce a catheter, sound or bougie it must first be passed up the penis to the extremuy of this angle : the point of the instrument must then be cut down upon, and from this opening the instrument can be readily passed forwards into the bladder. The examination made, and a stone detected it may, if a very small one, be attempted to be pushed forward by mis of a fiiiger passed up the anus into the urethra ; but a this could be practicable only where the dog happened to be a le one, it ismost probable that nothing short of the operation of lithotomy would succeed. To this end, the sound being m- POISONS. 181 troduced, pass a very small gorget, or otherwise a bistoury, along its groove into the bladder, to effect an opening sufficient to admit of the introduction of a fine pair of forceps, by which the stone may be laid hold of and extracted. CLASS VIII. Poisons, Mineral, Vegetable, and Animal. Poison, though a very popular term, is yet, in some respects, a vague and indefinite one; as substances that are most noxious and destructive to one class of animals are perfectly harmless to others. Henbane (hyoscyamus niger, Linn.), which is eaten with impunity by horses, oxen, goats, and swine, proves most baneful to the canine genus. Opium, on the contrary, may be taken in considerable quantities, by dogs, without serious injury ; but it rarely fails to prove fatal to the human subject. The phellandrium aquaticum kills horses, while oxen eat it with- out harm; and the hedgehog, we are told, will devour can- tharides with impunity in large quantities. Poisons have, there- fore, been divided into relative and common, or such as are hurtful only to particular classes of animals ; and those which prove destructive to all, as the several oxides of mercury, arsenic, and copper ; the concentrated acids, &c. &c. Dogs are not unfrequently poisoned either by accident or design ; and as the circumstance is sometimes discovered in time for relief to be afforded, so a knowledge of counter poisons, and of the general treatment proper on such occasions, form material branches of canine pathology ; and as also, when no relief can be obtained, it is still very desirable for the ends of justice (when wilful poisoning is suspected) to be enabled to establish the fact of administering, and of the nature of the subject administered ; so an acquaintance with the various substances commonly em- ployed for this purpose, the symptoms produced by them, and 31 2 182 MINERAL POISONS. the appearances that the parts acted on present after death, are necessary portions of the canine medical practice. The limits of the present work will necessarily confine me to noticing such articles only, as, by their popularity, are most likely to be made use of purposely to destroy, and such as chance may, with some probability, throw in the way of the animals themselves. Those who wish for further information relative to the effects produced on dogs by various poisonous agents, may consult Abbe Fontana, Orfila, Mr. Brodie, &c. &c, who have sacrificed more dogs, in experimental inquiry, than hu- manity dares to think of, though science might demand it. Mineral Poisons. Corrosive sublimate, or oxymuriate of quicksilver, is a most deadly and unmanageable poison to dogs, in doses as small even as five or six grains. Its effects are observed soon after it is taken, by the distress of the animal, by his frequent retchings, insatiable thirst, panting, and anxiety for a cool situation. Ihe mouth becomes swollen ; if the dose has been large, it appears ulcerated also, and emits a very fetid odour, which circumstance forms a very strong characteristic both with regard to the animal's having been poisoned, and also to the article employed for the purpose. As the symptoms advance, the retchings a e tinged with blood; the stools become liquid and bloody also; he heart beatsfaintly,butwith rapidity: the extremes become cold ; violent tremblings, paralysis, or convulsions follow, and death relieves the suiLr. On examination of the body afterwards, the whole alimentary canal, beginning at the mouth and pro- ceeding backwards, exhibits marks of the corrosive nature of the matter taken. The stomach, on being opened, wil appear lered with highly inflamed patches, and the villous fold, of its inner and rugose surface will present gangrenous and ulcera ted pot , and a ready separation of the mucous from he muscular oat with blood often suffused between them; winch «mu„ MINERAL POISONS. J.83 stances only take place when a most acrid poison has been swal- lowed. The intestines also shew appearances of great inflam- mation, particularly of their inner surface, which will be found sprinkled with gangrenous sjiecks, and, moreover, frequently filled with a thick bloody mucus. Such are the usual morbid appearances: but, satisfactorily to detect the presence of a poison, and the immediate nature of it, some of the liquid con- tents of the stomach and bowels, both before and after death, should be saved, and undergo a rigid chemical analysis. In general cases, the addition of potash to some of these liquid contents will occasion a light yellow precipitate when corrosive sublimate has been the poisonous agent5 ; but a practical chemist will employ many other tests. The medical treatment to be pursued in these cases consists in both endeavouring to envelope and to neutralize the acrid matter : the former may be attempted by means of a glairy fluid, for which purpose the whites of eggs have proved the most effectual remedies, beaten into a liquid, given in large quantities, and repeated as often as they have been ejected : when these are not immediately at hand, milk may be substituted. Mild clysters should also be thrown up. When the stomach is some- what appeased, give an opiate and castor oil. Large doses of soap, dissolved in water, have been recommended as a counter poison to corrosive minerals, or their preparations, and, in the absence of eggs, should be tried. Arsenic. — This powerful oxide is often given to dogs, and not unfrequently they find it for themselves in a state of mixture with other matters placed to poison rats. The effects produced by it resemble those occasioned by corrosive sublimate, except that, although they prove equally fatal, they are not apparently so interne. The mouth, likewise, is not usually affected, in an equal A ready, although not a very humane, mode of detecting the presence of poisonous matter, is to give to Cowls, birds, or any small animal, Bome of the early ejected contents of the stomach of the dog to which poison has been supposed to be given ; but this ought never to be attempted, unless the ends of justice imperatively demanded it, and no tests could be procured. 184 MINERAL POISONS. degree, by this poison as by the other. Dissection, also, detects similar morbid appearances to those above detailed ; but, unless a very large dose has been taken, there is not such complete lesion of the coats of the stomach and intestines, but the gan- grenous spots and the excess of inflammation are fully sufficient to detect the disorganizing action of a mineral poison. Instead of subjecting the liquid contents of the stomach and bowels to the action of potash, as directed when corrosive sublimate is looked for, it is usual to detect arsenic by applying the blue ammoniacal sulphate of copper, which will produce a lively green if arsenic is present. A red hot iron will also occasion these contents to give out a garlic-like smell under similar circum- stances. The treatment proper, in cases of arsenical poisoning, is to give sugar dissolved in milk, in considerable quantities, until it may be supposed that all the poison is evacuated from the stomach, when a similar treatment is to be pursued to that before recommended. Verdigris.— The rust of copper is often taken by dogs, from the careless practice of leaving acidulous remains of food in copper vessels. The effects produced are not unlike those al- ready detailed, but less violent; neither are the appearances after death dissimilar, except that the ulceration and gangrenous spots are less strongly marked. The presence of copper may be de- tected by the prussiate of potash, which occasions a reddish precipitate in the liquid contents of the stomach and bowels when added thereto. . The treatment in nowise differs from that detailed in mercurial poisonings. Lead.— I have frequently seen dogs fatally poisoned by drink- ing water from leaden vessels, or by lapping the water lett in the hollows of the lead coverings of areas, &c. The same occurs likewise from the licking of paint, which they may have acci- dentally smeared themselves with; and it is to be observed, that a smaller quantity of lead in this way is sufficient to prove fatal, MINERAL POISONS. 185 than would be supposed. The symptoms produced are vertigo, violent griping pains, vomiting, with purging stools in some cases, and costiveness in others : towards the close of fatal cases, paralysis and spasmodic twitchings take place. On dissection of these bodies, there is seldom observed imy lesion of the coats of either the stomach or bowels ; but the inflammation is intense, and appears usually in patches. 1 have also not unfrequently met with intussusception. The treatment is to be commenced by an active purgative, as sulphate of magnesia (Epsom salts). Should this be rejected, a ball with calomel and aloes, and a quarter of a grain of opium, may be substituted, and may be repeated until the bowels are perfectly cleared out. The body should be afterwards kept soluble by castor oil ; for I have always observed that a costive habit from paralytic torpor of the bowels remains some time after the action of lead. Quicksilver. — When mercurial ointment is rubbed on dogs, without muzzling or covering them, it is very common for them to lick themselves, and to become, by this means, fatally poisoned. In such cases the stomach is usually but slightly affected, but a diarrhoea of great violence follows, attended with bloody stools, the consequence of ulceration in the bowels. In these cases, commence the treatment by giving a mixture of castor oil and white of eggs, in equal parts, sufficient to remove the offending matter ; proceed next to wash off all the remaining ointment, and then give opiates and astringents. — See Looseness. From this detail of appearances produced by the more active mineral poisons, both before and after death (which are all drawn from numerous and well defined cases that too frequently came under my notice), it will be apparent, that it is not difficult to discriminate between the inflammatory symptoms brought on by their agency, paiticularly when full doses have been given, from those inflammations occasioned by cold or other causes. When caustic mineral salts or acids have been taken, tha symptoms ara always more urgent, the progress more rapid, and the pain and 180 VEGETABLE POISONS. distress greater than when inflammation has proceeded from other sources. The fcetor from the mouth, and the bloody vomitings and stools, are also strong characteristics of acrid poisons in the living patient: those to be gained after death are the inflam- mation and gangrenous state of the alimentary canal; but more particularly the ulcerated state of the stomachs and bowels, and the early tendency in the whole body to become putrid and de- composed. The foetor that comes from the diseased parts is likewise peculiar in these cases, being more than usually pungent and lasting ; so much so, that I have distinguished it three months afterwards° from the instruments, dress, and other articles used during the examination of the body : fortunately this can now be immediately removed by the chloride of lime. Vegetable Poisons. Opium.— In the former edition of the Canine Pathology, I stated that, as tar as my experience went, opium was not dele- terious to dogs when received into the stomach ; for that very large doses of the solid mass were invariably returned from the stomach, and that smaller, though yet considerable ones, pro- duced but little derangement of the system. Orfila, however, whose experience has been purchased by the sacrifice of whole hecatombs of dogs, asserts that opium will kill, although he acknowledges (and which corroborates my former remarks on it) that it is so variable in its effects, that he has often given very considerable doses without at all injuring the animal. When it does prove fatally deleterious, the symptoms detailed by him are convulsive efforts of all the muscular parts, succeeded by dejec- tion and universal paralysis. On dissection, little appearance of inflammation is visible in the digestive organs, but there is more of it in the lungs. Orfila likewise observes (which fully agrees , u is no, vm unusual for the solve,,, power of the gastric juice to erode „ JitZ coats of the stomach; but, in such case, the opening . one -mple T terminate one only, and always situate at that part where the gravUy o ££E55 J Placed it particular., in contact with the stomach, and «■ no other. VEGETABLE POISONS. I87 with my experience), that the narcotic effect of opium is not apparent in the dog by any dose taken into the stomach ; but it is a curious fact, that introduced either into the bloodvessels by injection, or into the intestines per ano, it exerts its narcotic in- fluence fully. Vomic nut, or crowfig (Strychnos nux vomica, Linn.)— This berry, or rather seed of a berry, is a native of the East Indies, and is a violent narcotic poison to many animals : to others it proves not equally noxious ; but it does not appear wholly inno- cent to any. It possesses great power, but is very unequal in its action, not only on different animals, but also on the same animal at different times, and under different circumstances. It is a common but a very erroneous prejudice, that it proves poisonous to such animals only as are born blind. It is a deadly agent, not only to the whole of the canine and feline genera, but it destroys hares, rabbits, horses, asses, and most birds. It is irregularly deleterious to man, fifteen grains having proved fatal to one, and a whole nut or seed has failed to injure another. Leuriero relates, that a horse died in four hours from a drachm only. Five or six grains are sufficient to kill a rabbit or hare. I destroyed a very large rabid Newfoundland dog in five minutes and a half by a drachm of it, which was given in butter. Half a drachm was given to another, of middling size, which destroyed him in twenty-eight minutes; and twelve grains proved fatal to a smaller one in twenty-five minutes. A watery extract is more quick, as well as more certain, in its action, a few grains of which seldom fails to kill in a few minutes, if given in solution : it acts less speedily when given in the form of pills. But as it is, under all circum- stances, not uniform in its action, so I cannot, as formerly, recom- mend it as a safe agent to depend on for the destruction of a dog. When it is actually necessary to destroy one of these valuable animals, humanity dictates that it should be done speedily, and in such a way as will prolong the sufferings as little as possible, and a note appended will point out one in unison with these 188 VEGETABLE POISONS. views. It is, however, sufficiently deleterious to make it very commonly resorted to on such occasions by malicious persons ; particularly as it can be easily procured, under pretence of destroying vermin of various kinds. Like opium, the nux vomica fails to produce any of its soporific effects on dogs, when intro- duced into the stomach ; but it occasions violent tetanic convul- sions, laborious respirations, and general torpor, and it thus kills by robbing the nervous system of its energy ; and that so speedily, that its presence is not easily detected by any morbid appearances brought on : neither are any means, unless imme- diately resorted to, sufficient to restrain its consequences. An emetic should be given within a minute or two after the exhibi- tion of the poison ; and this should be followed by a large tea- spoonful of mustard, to give a reasonable chance of success. Angustura pseudo ferrugincea. — A false species of angustura has entered into the shops of many druggists, and has occasioned considerable mischief. Some years ago, I unfortunately de- stroyed a very favourite dog by giving him, as a tonic remedy, this spurious article, which had been furnished me by my drug- gist, as the genuine angustura bark. This deleterious article, although it is decided by Humboldt to be nowise related to the angustura tribe, has yet been very generally diffused, and used as a substitute for the true bark*. Prussic acid. — In its highly concentrated state, this acid (which, it is fortunate, is extremely difficult to obtain, and still more so to preserve) is so active, that one, or, at the most, two drops applied within the eye, nose, or on the tongue, are suf- ficient to destroy life in a minute or two. It is to the presence of this acid that many vegetable substances, particularly all bitter kernels, owe their deleterious properties. The lauro cerasus, or cherry laurel, used in cooking, for the kernel-like flavour it gives under distillation, yields a water that proves 1 L. A. Phinch, a French apothecary, has accurately described the article in a memoir, entitled Notice Chimiquc stir les Angtislurcs dcs Commerce. VEGETABLE POISONS. 189 poisonous to dogs. The essential oils of the cherry laurel, and of bitter almonds, are both so strongly impregnated with prussic acid, that a very few drops given to the largest dog prove immediately fatal" . An extract also, made from either of these articles, speedily kills in a small dose. The effects produced by all these are nearly similar: taken into the stomach, they destroy by at once paralyzing the sensorium: introduced im- mediately into the bloodvessels, most of them exert a narcotic influence, but are no less certainly fatal. An emetic imme- diately administered, and followed up by active spicy stimu- lants, as mustard, pepper, &c, mixed with vinegar, afford the best chances of arresting the baleful effects of these potent articles. The Woorara, Lamas, Ticimas, Faba sancti ignatii, Upas an- tiar, and Upas tiente, are vegetable poisons, indigenous to southern and eastern climes, and by far more potent and deadly than our most noxious articles. Prepared with much art and care, these extracts retain their poisonous qualities a great length of time ; and the smallest puncture made with the finest instrument, as a sharp dart or arrow, embued with a solution of either of these extracts, proves fatal, in some instances, within a minute. Mr. Brodie has detailed some experiments made by him with these poisons on dogs, which shew their dreadful activity. Mons. de la Condamine's experiments at Paris are still more frightful pictures of their potency. a It is not unfrequently a subject of inquiry, how it may be possible to destroy a dog with least pain to himself, and least shock to the feelings of his owner. Although shooting and hanging are not, in themselves, painful deaths, yet the violence necessarily committed is revolting to one's feelings. It is both selfish and imprudent to familiarize the minds of servants to these acts. Whenever, therefore, cases arise (and many such do occur) where it would be infinitely more humane to destroy an animal than to prolong a miserable existence; and when the more usual modes are objected to on account of the violence and force necessary, either of these essential oils dropped on the tongue, or a very small ball made from the extract, will ex- tinguish life almost instantaneously, and without pain. 1.90 RABIES CANINA, OR CANINE MADNESS. History of Rabies. The popular term of madness among dogs has, of late years, given place to the more classical one of rabies; but a slight view only of the subject is sufficient to shew, that this disease yet wants a name more strictly descriptive of its nature and characters than any of those in general use. The complaint 9 The term rabies is, however, but a revival of its original name. Pliny calls the disease rabidus canis, and canis rabiosa is familiar in Horace, as well as in other ancient authors: but we have weightier objections to such no- mination ; for if madness be incorrect as depicting a state of wild delirium, un- governable fury, and mental alienation, which never fully exist in the very worst cases, and are present only in shadow in the majority of them; then rabies as significant of unqualified rage, fierceness, and promptitude to do mischief (Iracunde et rabie se facere aliquid, Ciceuo), must be equally so. Hydrophobia, by which the canine rabies has been sometimes called, is even more uncharacteristic; in fact, it is a complete misnomer; because a repug- nance to water, or dread of it, either taken inwardly, or when outwardly applied, forms no pathognomonic symptom here, but, on the contrary, may be considered as uniformly absent. Neither has it a full claim to be re- tained for the human malady: for hydrophobia is by no means invariably pre- sent in it; and if it were, it must have an adjunct to give it precision, seeing that a dread of water is a symptom common to several other diseases also, as hysteria, gastritis, angina, &c. Were it likewise peculiar to this complaint alone, and did it invariably mark and accompany every case, it must even then be objectionable; for water is not alone the dreaded object; and it can be only considered as a type of every thing liquid: for not only does every thiug of this nature produce equal horror, but also whatever can, by a forced analogy, recal fluids to the recollection, does the same. This circumstance has, therefore, occasioned hygrophobia to be proposed as a substitute for hydrophobia. Caelius Aurelianus informs us, that some of the old writers called it aerophobia, from the effect which the motion of the air even pro- duces : and others, determined to foil all criticism, have named it pantepkobia, or a dread of every thing. Dr. Parry has proposed rabies contagiosa as a substitute for hydrophobia ; but if he meant to apply it as a new term, he was in error; for Jos. de Aromatarius published a treatise Dc Rabie Contagiosa, at Frankfort in 1026. Rabies, however, equally exhibits an unfaithful picture of the irritability of the human character under the disease as of that of the dog: neither can we yield our suffrages to the adjunct contagiosa-; for the best writers are not yet agreed on the extent of its contagious character, nor of the animals capable of propagating it. 'I he term of cyntinlhropia. bj which it lias also been called, from a morbid supposition in the mind of the patient that he was personally identified with the dug, needs no comment; but RABIES CAN1NA, OR CANINE MADNESS. 191 itself is, unquestionably, one of great antiquity; for we have authentic accounts of it for more than 2000 years. It is de- scribed both by Aristotle and Diascorides. Other of the ancients likewise notice it10.— History has continued to furnish us with numerous traces of it, particularly in Europe, where it seems sometimes to have raged with epidemic fury, and at others to have been but little known11. In 1 500, Spain was ravaged by it. In 1604 it was very common in Paris12 ; and 100 years after this, Germany became the theatre of this dreadful scourge among its wolves as well as dogs. Historians of every age have left short but frightful records of its dreadful visitations ; and some works of magnitude, written by the authors of Spain, Italy, Germany, and France, have more fully detailed its ravages, but so blended with received errors, as to convey little information on the subject. The illustrious Boerhaave may, perhaps, be considered the first who, by attentive observation, threw light on the rabid malady in dogs13. In England, little had appeared worthy of notice before the account presented by Mr. Meynell. This celebrated sportsman published his memoir in the tenth volume of the Medical Commentaries ; and if his account of ca- nine madness does not exactly coincide with future representa- tions drawn from a wider field of observation, it nevertheless characterizes the disease with considerable precision; and, at in my own opinion there are less objections to cynolyssa, provided that "Kva-sra may be critically translated into torment from the bite of a venomous animal, which is said to be the case. >° Aristotle is however said to be the first writer who alludes to it. (Hist. Animal., lib. 7, cap. 22.) But his opinion that it was not communicable to man, shews that it was in his time but ill understood. Some doubt also seems to be entertained, whether Hippocrates, in his Coacte Preenotiones, intended to describe the rabid malady, when he says " Phrenetic! parum bibentes, strepituni valde pcrcipientes, tremuli aut convulsi." 11 Not that I believe the rabid malady ever arises spontaneously; but that sometimes the inoculation of it takes place under circumstances parti- cularly favourable to its rise and future propagation, as will be hereafter explained. 12 Journal de Henri IV, tome iii, p. 221. 13 Aphorism 1135, where, although some error is apparent, yet much truth also appears. 192 RABIES CANINA, the time it was written, was calculated to do infinite good, by banishing some dangerous and erroneous opinions relative to it. In 1806, rabies among dogs became very common in England, and abounded in the vicinity of London, where, during the next year, it increased to such a degree, that a day seldom passed without my being consulted on one or more cases of it : some- times I have seen three, four, or five a-day, for weeks toge- ther. In the two following years it continued to rage also : after which, for several subsequent years, it was less prevalent ; but it never became apparently extinct or rare as before. In 1820 it was again observed to be on the increase, and for three or four years continued alarmingly common, when it again moderated for a few following seasons; but since 1828 its ravages have exceeded even its former bounds. Of these latter visitations I have been a more quiet spectator; but of those which occurred between 1805 and 1820, I was a very active one. The publicity which attached to my attention to the diseases of dogs occasioned constant reference to me on the subject, and threw such opportunities in my way of observing this dire malady in all its varieties in both man and beast, as had pro- bably, at that time, never before fallen to the lot of any indi- vidual whatever". These opportunities, I believe, I did not neglect; it was a field so little trodden, that the few truths which had sprung up, were choaked by error; and the im- portance of the subject at that time was such, that it became imperative on those whose experience enabled them to do it, to set the subject in its true light, and to divest it of many gross and serious mistakes that hung about it; and which none but those whose opportunities of observation were great, and whose .Since .hat time, the opportunities -J^^^^^SS! greater than my own, uniting, as he was enabled o o rtiis ooBortunity of expressing my obligations to me s»i SLffKJ L Views Of the .natter, and for many valuable facts also. OR CANINE MADNESS. urn inclination to profit by them was also considerable, could do. Towards the close, therefore, of 1807, 1 placed before the public, in a Domestic Treatise on Horses and Dogs, a detailed account of rabies ; and soon after, being requested to furnish an account of it also for the Cyclopaedia of Dr. Rees, a condensed form of it was there inserted. It becomes not me to say further of these accounts; but others have said of them, that they furnished the most faithful picture of the disease that had, at that period, ever appeared15. I would 15 The alarming prevalence of rabies at the periods alluded to, produced in- numerable papers, tracts, and even volumes on the subject, of which there were but few that did not borrow something from one or other of the above sources. Of these writers some had the candour to own the obligation ; others contented themselves with adopting and then offering as their own, as much as suited their purpose: while one or two have even affected to dispute the cor- rectness of my views, apparently less from a legitimate search after truth, than to favour the different opinions they had formed of the subject. Among those who omitted any such notice, I must quote Dr. Gilman, who, in his justly ad- mired Prize Dissertation, may without hesitation be said to have borrowed much from me. Dr. Parry even observes of it, "that the symptoms of rabies were evidently taken from the article Dog, in Rees's Cyclopedia, or at least from the same source." Rabies Contagiosa, pp. 170-1.— Dr. Gilman had ready access to the author of that article, and he found him, when they met at the house of Mr. Boyd (a gentleman whose hand had been lacerated by a rabid dog), most ready to afford him every information on the subject, and to lend him the work quoted. If in any way I assisted in the great cause of humanity (and humanity itself was concerned in the production of so valuable a work as that of Dr. Gilman), I am gratified ; and had the ingenious author acknow- ledged the debt, it would not, I hope, have detracted from his fame, while it would have been creditable to his candour. I would also appeal to Mr. Lips- comb, and to a few others, whether they did not find me always ready to fur- nish them with all the information they sought for: but I never saw or heard of any one of them afterwards. They are welcome, but this is not my plan : on the contrary, it is my pride never, knowingly, to have committed a literary theft, by becoming a plagiarist: when I differed, I have endeavoured to express my dissent with candour; and where I have borrowed, I have owned the obli- gation: and of this I am assured, that there is full as much of sound policy as honest principle in the practice. Silence, however, is charity, compared with a method pursued by some authors, of abusing whatever they cannot confute. Of this unfair practice the Treatise on Rabies Contagiosa, or Canine Hydro- phobia!! by the late Dr. Parry, of Bath, is an instance. Dr. P., to es- tablish an untenable theory of his own, endeavours either to make the state- ments of others bend to the view he has taken, or otherwise attempts to throw discredit on such as he finds too stubborn for his purpose. From observation 1!)4 RABIES CANINA, hope, therefore, that, in the present detail, as much has been added on the subject to each several edition of the work, and to none made on three hydrophobous cases only, and on but one or two rabid ones he affects to disprove the vast mass of testimony offered by other observant and distinguished professional characters, during the last century; affirming, that by all of them, the disease, in both the human and brute subjects, has been equally mistaken in cause, appearance, and effect. The facts, which the unli- mited opportunities afforded to myself and Mr. You alt, enabled us to lay be- fore the public, militated much against these new views of Dr. Parry: and as the o-eneral credence given to our statements, and the weight which was at that time&attached to our opinions, would naturally offer some hindrance to their pro- cess, it became, therefore, a great point with him, to throw a disparaging shade over our writings in particular; and the consequence was, that they were neither examined with candour, nor contradicted with courtesy. On the contrary, to produce an appearance of discordance and opposition between their several parts, he selected detached and remote passages, and placed them continuously, purposely to give them the appearance of a contradictory whole ; in which way it is evident that the most perspicuous writer that ev er put ,,en to paper might be betrayed into the most glaring. seeming inconsisten- cies This dogmatic denial of palpable and well-known facts is of little con- sequence to us, comparatively with the extreme danger of reviving one of the most injurious errors which the barbarism of former times had retained ... some writings, and in some prejudices: but had not Dr. P. maintained that the rabid dog dreaded water as much as the hydrophobous man, he was fearful he should not establish his favourite theory, that the human and brute malady arc wholly the same in cause, appearance, and effect. " La, ryngea spasm 18, withDr P., the foundation of both diseases; and as the. hydrophobic symptom is one resulting from this spasm in the human subject, hydrophobia must ne- cessarily be present in the dog also ; and to establish the doctrine, he denies tes- timonies the most numerous, credible, and even then very generally es a- blished. Without a marked instance in which this laryngeal spasm was present ,n the dog, he pronounces every canine case, in which there is not a mamfest dread of water, to be spurious; and, in fact, any disease but rabies. How- ever in the total absence of facts, nothing remained but to resort to arguments; and of what nature Dr. P.'s were, maybe gained from the following specimen, which does not stand alone in futility.

Is it not also equailj true, that as experience and observation led us to distinguish between the pathognomonic signs as they appeared in the human and brute constitution, the names applied to the two diseases became effectually disjoined I Neither in the obscurity of the last century, or the more early periods, was canine madness so called, when specifically noticed. It was only so nominated cursorily, and in common parlance by persons not even pretending to scientific discrimination in general, or conversant with the complaint in particular.

Trolliet, p. 267. It may be added also, that we have innumerable instances of names borrowed from the human and applied to the brute, and vice versa, from an ideal resemblance ; although the designation might be essentially as completely a misnomer as the present. Towards Mr. Youatt, Dr. P. acted with even greater want of urbanity ; for an intimacy in early life with his father might have lessened the severity, even if it could not ward off the justness of his criticism. Yet with a feeling that does Mr. Youatt infinite credit, his retort is thus mildly couched, — "Let this uncan- did review, and gross mis-statement of some cases, published by me fifteen years ago, be now forgotten. The wound rankled for awhile, and the more so, as inflicted by the friend and fellow-student of my father. He now sleeps in peace. He was a scientific practitioner, and a good man." The cases alluded to by Mr. Youatt, and which were so unmercifully handled, appeared in the Medical and Physical Journal, and in the London Medical Repository ; and were drawn with that perspicuity and accuracy which mark his other scientific productions. That they were faithful portraits of the disease, his extensive op- portunities and habits of observation will vouch, and every other author ac- knowledges; yet Dr. P. denies the existence of every one of these as a true instance of rabies : on the contrary, so well versed does he think himself in canine pathology, that, by the mere statement of symptoms, he takes on himself to pro- nounce some of them Bronchitis, some Pneumonia, and others pure Inflamma- tion of the Fauces ! ! ! What opinion must Dr. Parry have of his own discrimi- nation, who could thus, on the questionable evidence of one or two cases only, and those most unsatisfactorily examined, question and deny the united testimonies of two persons, who could have no interest in deceiving, but every stimulus to offer the truth, and whose united opportunities extended to the per- sonal and minute examination of many thousand cases ! .' ! As regards this truly acute author, and I believe generally respected man, I would say, with Mr. Youatt, ilRequiescal in pace;" but I conceive the cause of truth rendered it imperative on ine to resist this attack as I have done; for Dr. Parry must ever be considered as a formidable antagonist, wherever science offered an arena; and as the " Addicti jurarc in verba magislri" is apt to influence the opinion of those who either want leisure, inclination, or ability to think for them- selves, and as I conceive that the errors he advocated were of vital import- ance to the safety of mankind, I do hope to rebut them, and to make the con- trary apparent in the course of my description of the disease. N 196 RABIES CANINA, mind, the errors and prejudices with which the consideration of it was fettered. Although, for ages, even, the plague has hardly been more dreaded, yet in this, as well as in other countries^, no equally important subject has been less understood or more mis- represented. As already shewn, its popular name ol madness conveys an erroneous and hurtful impression with regard to at; and where it has been called hydrophobia, it has tended to keep alive an absurdity greater than the other. The wormed dog is still by many thought to be rendered incapable of taking the disease; by others, he is only harmless if he does become affected : both are errors of the grossest kind, and lead to very serious dangers. That a mad dog carries his tail between Ins legs -that he is instinctively avoided by others-that bread meat &c. besmeared with the saliva, blood, or any of the secretions of a mad dog, is refused with horror by others-that the to e of a healthy dog, should he become at any time afterwards ratod, is dangerous-are all equally erroneous, although even now very F ^teUstory of the rabid malady may properly commence by an inquiry into its origin.

The human diseases quoted, are by long experience now very generally allowed to be confined to a contagious origin only ; for it is well known that these maladies were not indigenous to any of the newly discovered countries, however extensive their tract, and whether intra or ex- tra-tropical, but that they only followed the march of their in- vaders. Now, as canine madness stands precisely in the same situation with syphilis, small-pox, and measles, there being yet many countries where it is unknown ; are we not warranted in concluding, that neither does that also now ever arise sponta- neously ? But we must not content ourselves with analogy in searching after important truths, and this is a most important one ; as upon it must be grounded our capability, or otherwise, of a total extermination of the disease. Opinions grounded on experience are valuable ; hypotheses from minds accustomed to deep reasoning and extensive research are to be respected ; but it is on facts only that we must mainly rest. There are authorities of respectability who maintain that rabies is yet spontaneously generated^ ; and if such be the case, no legal enactments of what- 17 The illustrious Boerhaave seems to have indulged such an opinion. " Oritur fere semper ab aliis animalibus prius rabiosis suscepta contagio ; tamen et sponte quibusdam orta legitur et observatur." Aphorism. 1130. Sauvages favoured an opinion of its present contagious origin, and Orfilahas even carried the capability into other animals also. Dr. Hamilton, an elaborate writer on rabies, advocates the probability of a spontaneous origin from a new poisonous compound, gene- rated from putrid sordes, surrounding the animal, when the body is in a particular situation or condition. Query, What situation or what condition ? The rabies which Professor Rossi roduced by keeping cats shut up in a room was sympto- matic, and not the specific and communicable disease. Majendie, Dupuytren and Breschet, subjected dogs to the utmost state of filthy and close confinement for a long time ; and though they became very generally diseased, not one be- came rabid. If putrid animal sordes could originate rabies, how often must it break out among the dogs of the lower class of dog-dealers and fanciers in London, where hundreds of birds, rabbits, guinea-pigs, &c. with every variety of dog, are confined in one small close room, or cellar? neither is it probable but cases of dose confinement must have been frequent in those countries which it has never yet visited. Er. Gillman likewise embraces a similar opinion appa- rently on the authority of a single case, the correctness of which there is great reason to doubt. Mr. Coleman also advocates spontaneous origin from the same causes with Dr. Hamilton ; and such an opinion, from such a source, I am both N 2 198 RABIES CANINA. ever severity, short of the extinction of the whole race, could se- cure us. There are others also (and hy much the most numerous, and, without any offence to the former, by much the most ex- perienced) who maintain that the disease is never now of spon- taneous origin18. My own opinion, formed on an acquaintance with it of twenty five years, in a great many of which the rabid cases amounted to several hundreds per year, is most decidedly in favour of the contagious origin of the disease, and none other. While 1 was thus in the midst of it, I never met with one instance where it occurred in a dog wholly secluded from the access of others. I have met with cases where the utter seclusion has been peremptorily stated ; but not only have such statements, on ex- amination, invariably been found untenable, but they have served, inmost instances, in a remarkable manner, to confirm the opinion here advocated'9. Great as my opportunities have been, they, surprised at and sorry for. I am naturally surprised at so acute a reasoner falling into, what I deem, an error, in the face of so many facts confirmatory of its contagious origin only. I am sorry for it, because in a teacher deservedly so high in estimation, the error is likely to be diffused Dr. EU.ot.on is also among thisuumber ; and Mr. Dewhurst, a very respectable medical pract.tioner likewise ranges himself on this side, and details a most dub.ous case which he insiders in proof of it, in No. 32 of The Veterinarian, but wkch is most ably answered by Mr. Youatt in No. 33 of that work, where he de- monstrates, that the morbid appearances after death were c early not those of rabies, and the symptoms, while living, Mr. Dewhurst was unable to give.

His sentiments on this head, therefore, cannot fail to have weight ; and what are they ? After debating the point in his pamphlet be- fore noticed, he says, "I think we are justified in concluding, from the foregoing statement, that rabies is produced by inoculation ■ alone." The "I think" was pure parlance, and meant assurance strong, as reference to the work will shew. he promptly informed me, that if the dog was so, he certainly must have be- come so without infection (which he knew was in direct opposition to my opinion) ; for that this dog, which was a very great favourite, had never, for many months, been out of doors alone, nor, indeed, at any time, out of the sight of either himself or his valet, who .was also attached to the dog, and had the ex- press care of him when his master was absent. As, therefore, neither of them had ever seen him bitten, they were positive on the subject. Anxious to arrive at the truth, where so important a matter was concerned, I commenced a close examination of the other servants, and it was, at length, remembered by the footman, that one morning, when the master's bell rang for the valet to take this dog from the bed-room, as he was accustomed to do, his absence occasioned the footman to answer it; and this man distinctly recollected the dog accompanying him to the street door, and also that, while engaged in receiving a message brought, he distinctly remembered that the dog went a little way into the street, and was suddenly attacked by another that passed, seemingly without an owner. Here was an explanation of the apparent difficulty: this passing dog, there is little reason to doubt, was rabid, and, pursuing the usual march of mischief, he bit the favourite.' — Another case, even more confirmatory of the possibility of be- coming mistaken on this subject, is that of a Newfoundland dog, which was con- stantly chained to his kennel during the day, and suffered to be at large only during the night within an inclosed yard. This dog became rabid, and, as no dog was known to have had access to the yard, it seemed to be an established certainty in the mind of his owner, that he generated the disease spontaneously. This case I also sifted with great perseverance, to elicit the truth ; which was this ; that the gardener to the family remembered, one night in bed, hearing an unusual noise, as though the Newfoundland dog was quarrelling with another, but which, from the dog's confined situation, made him believe was impossible, and he therefore took no notice of the subject. He also recollected, that, about this time, marks of a dog appeared in liis garden, which, on account of the height of the wall, surprised him ; and he further remembered, that remains of hair were discovered on the wall which separated the garden from the yard where the dog was confined, but which circumstances, until strict inquiry was 200 RABIES CANINA, The Alleged Causes of Rabies. The remote causes of spontaneous rabies, as advocated by the favourers of that doctrine., are various. Heat has long been con- sidered as a grand agent, but the direct proofs to the contrary are fast wearing away this prejudice. It is known that many countries under the torrid zone are entirely free from canine madness ; and in such as it is found, it does not appear to gain any accession to its frequency or morbid character20. We have Barrows' authority for stating, that it is almost, if not entirely, unknown over the vast continent of South America. In many of the western isles it is a stranger; and, in Egypt, Volney says he never heard of it. Larrey, Brown, and others, inform us, that it has never visited the burning clime of Syria. Neither is it more prevalent in cold climates ; and although it sometimes visits northern latitudes, it shews no preference for them, and, in Greenland, is said to be altogether unknown. In temperate cli- mates, on the contrary, it is most prevalent, not perhaps owing any thing to an extra-tropical situation, but merely because in such latitudes the most populous countries are usually situated ; and, in such, all matters of interest are more likely to be noticed. In the United States of America, it is sufficiently frequent", and throughout Europe we are but too well acquainted with it. made, had excited no attention. About the same time, the neighbourhood, it ap- peared, had been alarmed by the absence of a large dog belonging to one of the inhabitants, which had escaped from confinement during the mgh^ evidently under symptoms of disease. Here, also, a ready solution of the d.mculty oc- curred and there is no reason to doubt but that the cases detaded M Lr Oilman and Mr. Dewhurst originated under circumstances equally acc.dental and unnoticcd.-SVc Mr. Youatl on the subject, also Vet. 3d. » It cannot, however, be denied, that heat accelerate* , the _ attack ,n such as have been bitten, particularly when conjoined with great boddy excitement In this way, a dog that has been inoculated, but in which the d.sease m.ght not ap- pear probably for weeks, by taking long and severe exercise .n very hot wea- S er E almost certain to be attacked with it the next day.

OR CANINE MADNESS. 201 Seasons have also been alleged as the probable cause of mad- ness among dogs ; and, as might be supposed, simmier has long been famed for its superior germination of it ; and the dog-days probably owe their name to the fancied prevalence of it then1. But it is now sufficiently notorious that rabies is not more preva- lent at one season than at another2. The quality and quantity of the food has been assigned as a cause of rabies ; but in dogs which have been accidentally sub- jected to a deprivation of food, bordering upon starvation, it never yet took place3. Repletion has never occasioned it, al- though it has proved the parent of many other inflammatory affections. Putrid food has been fully proved to have no title to generating it : neither would it, a priori, be Hkely to produce it in predatory animals, whose stomachs must, by nature, be form- ed to subsist on matter in various stages of decomposition. In Lisbon, in Constantinople, and other eastern cities, dogs are the only scavengers; and, at the Cape of Good Hope, Barrow informs us, the Caffrees feed their dogs wholly on putrid flesh, and no such disease is seen among them. Abstinence from water is an old and popular supposed cause of madness ; but, in India, where, from the drying of the water-tanks, many brutes perish ; 1 When Sirius reigns, and the Sun's parching beams Bake the dry gaping surface, visit thou Each ev'n and morn, with quick observant eye, The panting pack.

M. Andry, in his Rdclierches sur In Jlage, Paris, 1780, observes that January the coldest, and August the hotest months, furnished the fewest instances. 11 n'est point vrai que cette maladie soit plus commune pendant les froids rigoureux de l'hiver, ou les chaleurs ex- cessives de V6t6, qu'au printemps et-en automne. — Trolliet. 3 Among innumerable experiments which have been made, I will only notice the cruel but striking one at the Veterinary School of Alfort. Three dogs were chained, fully exposed to the heat of the sun. Nothing but sailed meat was given to one ; water alone to the second; and neither food nor drink to the third. As might be expected, every one perished ; but neither of them exhibited the slightest symptom of rabies. — See Dissertation sur la Rage, by M. Blcynier, Paris. 202 R AHIliS CANINA, and in northern latitudes, where the supplies are frozen, yet mad- ness is not observed to be the consequence of either. In fact, in the rage for experiment, dogs have been purposely subjected to all these supposed causes, but without having once produced the disease. It is unnecessary to combat the opinion of Dr. Mead, and others, that an acrid state of blood, from the want of per- spiration in the dog, is a remote cause of madness. Neither have we more reason to suppose that any state or peculiarity of atmosphere can give rise to it, although it may favour the exten- sion and activity of the contagion. But if none of these causes engender the rabid malady, can we yet attribute the extreme variations in its prevalence at one time in preference to another ; its visitation of one district, and its al- most total absence from those around it ? Can we account for these on the simple principle of contagion ? that is, must every dog be actually inoculated with the rabid virus ? In this I feel myself warranted in replying in the affirmative ; for there is little reason to doubt, that, in certain situations, and during certain seasons, peculiar changes take place, which prove decidedly favourable to the germination of the rabid virus* ; and to which we ascribe its appearing endemial at one time and epidemial at another. The same circumstances, also, may occasion a more early development of the disease (as I have already proved with regard to heat and excitement), and in this way increase its ap- parent prevalence, by bringing numerous cases together, which would otherwise be spread over a greater extent of time. Was the dog the immediate species of the canince in which rabies first originated ?-This is a question not easy of solution, thouo-h many from localizing their views, would be led to promptly answer yes : but where the wolf is still found in great numbers, he has equal aptitude to take on the disease by inoculation; even 4 U was the decreased predisposition to take on the disease a, that parti- culartime, which made the experiment of Dr. Hertwig, veterinary professor a SSta so unproductive. He inoculated fifty-nine dogs wiA the mus and yet o^ly fourteen became rabid : at. another time it is not unlikely that the num- bers might have been very dift'ercnt. OR CANINE MADNESS. more disposition to spread it ; and at least equal capability, from the virulence of Lis virus, to make it certain in effect : some accounts would even give to it a most frightful activity5. A priori, therefore, we have as much right to assign the palm of priority to the wolf, as to the dog; and could this attached friend of man speak for himself, he would willingly give up his claim : as, however, the traditions of three thousand years have assigned it to the dog, let it rest. The for, we have also suf- licient proof, is a subject of the affection ; yet the extreme rarity of vulpine rabies, even in those countries where he abounds, would lead us to conclude, either that his inherent aptitude to germinate the contagion is small, or that his solitary habits ex- clude him from attack. Of the chacal or jackal, as a canine con- genor, I know nothing decisive : he has been said to have been seen rabid ; but I believe the authority is questionable. Some of the favourers of a spontaneous origin in the disease include the cat also : we certainly do know that this animal is capable of re- ceiving and of communicating it, but we have not one authentic fact of which I am aware to give us reason to suppose it is ever generated by grimalkin : there have been also statements of the same kind with regard to other animals, and to man also ; but they are wholly unauthenticated, and very generally disbelieved. Wliat rabid animals are capable of communicating it. — For a long time, the facts which should elucidate this point accumulated so slowly, and then were so discrepant, that it was difficult to come to any conclusion on it. At first the propagation was thought to be limited to the canine and febne genera : gradually 5 Fortunately, the ravages of the rabid wolf are unknown among us; but in France, Spain, and Germany, they are but too common. His savage nature makes him, under the excitement of this inflammatory disease, highly fero- cious, and he seeks objects of every kind wherein to propagate his own suffer- ings ; and as his size enables hiin to reach it, so he commonly inflicts his wounds on the face, and thus he more certainly insures a fatal issue. The ex- tent of some of these ravages may be gained by reference to Astruc Mem. Montpcllier, 1819; d'Arluc Recueil Penodique, torn. 4; Baudot Mem. de la Soc.

'20-1 RABIES CANINA, we were constrained to admit that other quadrupeds besides these had by their bite produced it also ; but as such as could be well authenticated were partially if not wholly carnivorous, so the ca- pability was then, in the opinion of many, confined to them0. Other facts are on record which have brought man within the propagating class? : the horse, badger, and pig, also are more than suspected, and the result has been, that Mr. Youatt states his full conviction that " the virus of every rabid animal will communicate the disease." This gentleman's own opportunities for conclusion, united with the ardour of his research, afford a pre- sumption that such may eventually be found to be the case : it, however, becomes us to pause in the absence of conclusive evi- dence. Our extended experience has therefore taught us, that quadrupeds universally seem obnoxious to it ; the feathered tribe appear also not exempt; but how much lower in the scale the liability extends, we are yet to learn. It was the opinion of Kuzard, founded on a series of experiments, and again repeated at Alfort, as well as of Professor Betti, of Florence, an ex- perimentalist also, that herbivorous animals are incapable of producing the rabid malady. Drs. Vaughan and Babington also equally failed lo propagate it from the herbivora. Others likewise of our most eminent medical practi- tioners think the propagating power confined to such animals only as natu- rally employ their teeth as weapons of offence. Sir Astley Cooper, and Mr. Coleman also, I believe, think thus, and it must be allowed that there is a great air of philosophy in the limiting the power of generating the disease to the carnivorous and pugnatory classes. But it must, at the same time, be al- lowed, that some objections present themselves to the theory ; one of which is, that the human saliva has produced rabies by inoculation : to which, how- ever, it will probably be replied, that man is half carnivorous ; he has also canine teeth : by which mode of argument casuists may attempt to save the credit of the theory as regards the horse, which has been said to have pro- duced the disease ; for he also has canine teeth, and most certainly uses them pugnaciously in retaining his hold first taken by his incisors. ''On the 19th of June, 1823, in the presence of numerous medical students, MM. Majendie and Breschet, in the H6tel-Dieu, absorbed some of the saliva of a man tlv n dying of hydrophobia, by means of a bit of rag, and conveying it only twenty paces from the bed of the patient, they inoculated two healthy dogs with it: one of these became rabid on the twenty-seventh of July, and bit two others, one of which so bitten was attacked on the twenty-sixth of August. Mr Earlc, of St. George's Hospital, also inoculated several rabbits with the saliva of a woman with hydrophobia, some of which became rabid. Dr. OR CANINE MADNESS. 205 The saliva of a rabid animal contains the rabid virus. — Is it the only animal secretion which is thus empowered ? This is a point not yet determined. It has been thought, that the frothy secretion about the mouth was principally bronchial. In the hu- man subject it is possible that it is so ; but it is more than proba - ble that it is not entirely so, but that the saliva is in intimate mixture with it. It has been a question, therefore, whether this bronchial secretion is capable of producing the disease. Mons. Trolliet, a French author of some repute, asserts, that this alone is the vehicle of contagion8 ; and, to make good his premises, he asserts, that the salivary glands, living or dead, present no marks of affection ; but the mucous bronchial surfaces always do. On this I have to remark, that the statement is totally at variance with my own observations ; the salivary glands being, as far as I recollect, in every instance, involved in one common inflamma- tion with the parts around, themselves being also individually, sometimes very highly, injected, and always enlarged ; while, it must be observed, the bronchiae are not always marked with traces of active inflammation. In this respect, Mr. Youatt's ex- perience coincides with my own9 ; but we both regret that we Zinche, of Jena, has proved that the common fowl can be made rabid by the canine virus. Valentin. Let. stir la Rage, Jour, de Med., vol. xxx. This will serve to strengthen the faith in the account of Mr. King, of Clifton, who pro- duced rabies in a fowl by means of the saliva of an ox, which had just died of that complaint. 8 Propositions Aphoristiques : 1.

To those whose faith is strength- ened by the antiquity of an opinion, it may be observed, that the ancients were universally impressed with a belief that the saliva alone contained the morbific virus; and particular families or tribes (the Marii and Psilii, Africans who * 206 RABIES CANINA, have not, before this, put the matter to the test of experiment ; and it would have been more satisfactory had M, Trolliet done the same. It is enough, however, for our present purpose, that we know that the saliva is, at least, the principal medium of com- munication from the sick to the healthy. It has analogical proofs, also, that it is the only one ; the blood, the milk10, and the flesh, have all been proved to be innocuous, while the saliva enjoys a potency which even powerful chemical agents cannot destroy11. Among the dissenters to the rabid virus being confined to the salivary secretion, are Drs. Hamilton and Bardsley. These gen- tlemen entertain a notion that the infection may be received, in a state of vapour, either through the pores of the skin, or by inhala- tion, or by both1*. But this doctrine is now discredited, and was never supported by palpable facts. practised at Rome, were of this kind) enjoyed the privilege of drawing out the poison in these cases by suction with the mouth. — (Plin.

Another, who was inoculated with morbid saliva, mixed with a strong solution of arsenic, wholly escaped; while a cat, inoculated with the same saliva, diluted with a tincture of cantharides, became rabid nine days after A rabbit was inoculated with a mixture of rabid saliva and volatile alkali ; it died on the eleventh day. Another, inoculated with virus and human saliva, escaped disease. A dog, inoculated with the same morbfo saliva, mixed with a diluted solution of phosphorus, although he became sick on the tilth day, nevertheless escaped infection. A cock, inoculated w-.th the same saliva, mixed with some of the gastric juice of a cat, died on the fourteenth ^12 The work of Dr. Hamilton is, as might be expected, elaborate, but theo- retical. Dr. Bardsley has united what he supposes proofs with his theory ; but as along experience, among those best fitted to judge of tlie subject, has never confirmed them, it may be supposed that they owed their origin to other sources The principal fact on which he grounds his opinion relative to the capability of receiving rabies by means of infected vapour, was gained from Mr Trevalyan's experiments. This gentleman, after losing almost a pack of hound8 by madness, was led to suspect that contagion might lurk u the sur- rounding materials of his kennel. The litter was carefullj destroyed, .he OR CANINE MADNESS. 207 Can the poison make its way into the constitution through the medium of an epithelium, or mucous surface, as that of the nostrils, lips, or eyelids13? involves an opinion of greater probability, and certainly of equal importance, and is a question on which nega- benches were scalded, the joints, crevices, &c. were painted, and the walls white-washed; the pavement was also scalded: nevertheless the rabies again appeared. Mr. Trevalyan was now more than ever convinced that some subtle contagion lodged concealed within the apertures of the benches or pavement ; the whole was therefore removed, and the edifice was again white-washed and painted, after which no rabies appeared. Puzzling as this appears to one who argues that no contagion can lurk thus unseen, and be generated by inhalation, it may yet be satisfactorily accounted for by another statement, equally true, that fell under my own immediate cognizance. I was requested, in 1821, by Mr. Yates, of Tring Park, to examine two servants, a huntsman and whipper- in, who had been bitten by a hound evidently rabid. I cauterized the wounds many days after the accident, and neither of them felt any future inconvenience from the wounds. Three or four of the hounds had already become rabid in succession, and it was proposed to destroy the remainder ; to which I objected, and recommended that a minute examination should be made of them individually every day. Every now and then, however, for months afterwards, an individual was attacked with madness, and, at length, the whole were destroyed, and Mr. Y. procured anew pack, which have never become afFected, although living in the same kennel, without any precautions having been made use of to prevent la- tent contagion; which I made it a particular point of ascertaining, having many subsequent opportunities of personal inquiry. 13 The following authorities lend themselves to the opinion, that a sound mu- cous surface can receive the contagion : — Palmerius, de Morbis Contag. ; Por- tal, Obs. stir la Rage, p. 131 ; Matthieu in Mint de la Soc. Rot/ale de Mid. p. 310, &c. A father, when dying of hydrophobia, is said to have imparted a fatal kiss to his infant. On the authority of Dr. Perceval, Dr. Bardsley tells us of a man who, during his sleep on the ground, was licked about the mouth (but not bitten) by an infected dog. He was seized with hydrophobia and died of the disease: but this case, it should be remembered, was always considered questionable. We are also told of a- man, who was not known to have been bitten, becoming hydrophobous ; but it was afterwards recollected that he had made use of his teeth to untie a knot with which a rabid dog had been hung. On the other hand, it is known that the salivary spume has reached both the eyes and mouth of persons when in attendance on hydrophobous patients. If this were an ordinary source of inoculation, we must naturally meet with the consequences; instead of which, no such case is on record. Neither would the practice of sucking out the rabid virus have been so common among the an- cients, as to have become a profession principally confined to certain families, as already noticed. It is also very probable, that, if the disease really have been taken through the means of a mucous surface, it was an abraded one: how often are the lips chapped, and how common is it to have little excoria- tions in the mouth, or on the nose, eyelids, &c. ? ~08 RABIES CANINA, tive and affirmative alleged facts can be ranged in almost equal numbers ; it, therefore, will require further time, and still closer observation, to set the matter at rest. Every poison is governed by its own laws; were it otherwise, we might analogically con- clude a mucous surface to be open to receive the virus, for such surfaces receive the syphilitic poison. With still less probability, and without any authentic facts to support their theory, some suppose that the surface of the skin throughout is capable of be- ing penetrated with the poison, by the simple application of it to the unabraded surface14. A very few only have been led into an opinion that it was possible for the rabid virus to enter the circu- lation through the medium of matters taken into the stomach. The activity of the rabid virus; does it remain after death, and how long? is a question not yet solved. Mr. Youatt thinks it ceases with the life of the animal ; and it may do so. Nothing, however, but a series of experiments can determine this ; and, until then, I should be most unwilling to try it on myself. Having thus traced the rabid poison from its rise and origin to its insertion into the animal body, let us now proceed to inquire, what are the chances that it will prove baneful; what time usually intervenes between its insertion and active operations; and, when so acting, what are the symptoms it produces, and what its supposed modus operandi ? Of the numbers bitten by a rabid animal, many escape without infection. — A variety of circumstances may tend to this favour- able issue, among which may be reckoned the intervention of substances between the teeth of the biter and the flesh of the 14 A fact sufficient to negative the power of the general cuticle to absorb the rabid virus, is my own safety. When the disease was very prevalent, my hands must have been, almost every day, in contact with it. I was become, by habit, entirely fearless of dogs generally, and equally so of those that were rabid. I examined them unhesitatingly ; assisted my servants to force their medicines while living; and examined them without precaution when dead: and I may safely assert, therefore, that I have had rabid saliva over my hands more than a hundred times. Mr. Youatt's prosecution of the matter, and his present health, are equally confirmatory instances of its inadmissibility through an unabraded cuticle. OR CANINE MADNESS. 209 bitten ; as the wool of sheep, the thick hair of some dogs, and the clothes of human persons. The inherent aptitude in different classes of animal bodies to re- ceive it is, also, not the same. — As might be expected, it is greatest in the caninae, particularly in the dog and wolf; yet it is proba- ble that not one-half of either of these germinate the virus received. The proportions among other quadrupeds we are more in the dark about. Mr. Youatt thinks that the majority of inoculated horses perish, but among cattle he is of opinion the proportion is less. I should, however, myself think, that both enjoy a much greater immunity than dogs ; otherwise we should meet with more rabid cases among them in agricultural districts than we do15. Human subjects., both constitutionally and for- tuitously, are least obnoxious to it16. Neither is there room to 15 Are we not, also, warranted in concluding this aptitude in the cat to be small, from the fact that rabid dogs seek these unfortunates with an instinctive aversion, and great numbers must by these means become bitten? yet a rabid cat is, comparatively, a rare occurrence : but it is to be observed, that when ra- bies does make its appearance in the cat, it shews itself with much of its phre- netic and mischievous characters. 16 In the human subject, there is reason to suppose that the interposed dress wipes the saliva from the teeth, and saves many who would be otherwise fatally inoculated : but the inferior predisposition in man to receive the con- tagion, exonerates still more. Out of twenty persons, bitten by one dog, Mr. Hunter informs us (althongh no prophylacticks were employed), one only be- came hydrophobous. Dr. Vaughan relates, that between twenty and thirty persons were bitten by another dog, out of which number, also, one only was infected. If it were, however, possible to credit the accounts of the ravages of wolves, we might be led to believe that a superior degree of certainty at- tended the contagion, even to. the human subject, when received from them. Mons. Trolliet relates, that of twenty-three persons bitten by a wolf, thirteen were infected with the disease. In the M&m. de la Soc. Roy. de MM. p. 122, mention is made of two human persons, with many horses and cows, being bitten by a rabid wolf, in September 1772, and that every one of these became af- fected. Baudot, also, gives an account of no less than forty oxen, cows, horses, dogs, &c, bitten by a mad wolf, in the month of June 1765, the majority of which died. I might multiply these instances, handed down to us by the indus- try of collators; hut the authorities arc, in general, so dubious, that they should be received with caution. It, however, may be admitted, that as the wolf usually attacks the face, which is not only uncovered, but, it is probable, is more certainly and more quickly acted on than other parts of the body, so, in this way, greater danger may arise from the rabid wolf than the rabid dog. 210 RABIES CAN1NA, doubt that the animal frame, generally, is sometimes less apt than at others to receive the contagion, dependent probably on a con- stitutional idiosyncrasy generated within, or gathered from, the operation of external circumstances, as peculiarity of situation, variations in temperature, qualities in aliment, &c. &c. Not only do facts coincide with this opinion, but it is impossible otherwise to account for the epidemial as well as endemial character which the rabid malady sometimes assumes1?. The intervening time between the inoculation by the rabid bite and the appearance of the consequent disease, is very variable in all the subjects of it : in the majority of instances, the effects ap- pear in the dog between the third and seventh week. Cases, how- ever, do now and then occur, where they have been protracted to three, four, or even a greater number of months. Although, therefore, caution should not be lost sight of, even after eight weeks have elapsed, yet the danger may be considered as incon- siderable after that time. A week is the shortest period I have met with between the bite and rabid appearances. Mr. Youatt never saw a case with less than seventeen intervening days. In the horse, as far as my own experience goes, the average time is the same with the dog : Mr. Youatt, however, hints at one after four months. In cattle, the probatory period seems much the same as in horses and dogs. In the human it may appear in a month, or be protracted to three or four ; and Mr. Henry Earle authenticates a case within Ins own knowledge, in which the hy- drophobic symptoms were delayed until a twelvemonth after the bite. Of the extraordinary instances we read of, which have 17 I have before hinted, that accidental circumstances maj hasten the attack, particularly as would appear by excitements of the vascular system. Thus it follows extraordinary exercise ; and the oestrum or heat of bitches will rouse the dormant poison into action. The certainly of the attack is also, I believe, greatly increased, as well as hastened, according to the part bitten. I have very seldom known any animal escape which was bitten in the head or face ; and I have, in almost every instance, observe. I less time to intervene in these cases than in such as were bitten elsewhere; and the same has been noticed by others also. OR CANINE MADNESS. 211 been protracted to five, twelve, and even nineteen years, I do not believe one. Symptoms of Rabies. I shall now proceed to describe the pathognomonic and occa- sional indications of the rabid malady, premising that the varie- ties in both, but particularly in the latter, are so numerous, that hardly any two cases present themselves under a directly similar aspect18. It is however certain, that, by the aid of the pathogno- monic symptoms, the disease may be commonly detected without fear of mistake. The extent of the former, and the necessity for a distinct notice of all the varieties of the latter, render a perspi- cuous account of the malady extremely difficult, and necessarily extend it beyond the limits of a summary. Rabies sometimes commences with dulness, at others with a more than usual watchfulness, and restlessness : it is often ushered in by some peculiarity of manner, some departure from the ordi- nary habits of the animal, or by the introduction of new ones. In many instances, but more particularly in the smaller and closely domesticated kinds of dogs, this peculiarity consists in a disposi- 18 I have great reason to think that much of the discrepancy we meet with in the various accounts that appear relative to rabies, arises from the confined field of observation from whence they are drawn. One enters on a detail of it as it has appeared in one or two individual cases that accidentally fell under his notice; another describes it as it is found to exist among hounds, pointers, or other large dogs only; and a third draws a portrait of it as it shewed itself among the smaller and confined breeds kept about the person ; and yet each (not considering that original character and habit stamp a still further variety on a disease already sufficiently variable) expects all future cases exactly to coin- cide with his own statement, or that they should fully bear him out in his own news of the subject, In the larger breeds of dogs, and particularly in ken- nelled ones, as hounds, &c., where close domestication has not wholly reclaimed their native ferocity, rabies may, and indeed does, shew itself with much of that wildnessand mischieTOus character that has gained it the name of madness. The rabies of the wolf and fox, although close congeners of the dog, and that likewise of the half-reclaimed cat, isralways stamped with a ferocity and malig- nance of character that is foreign to what usually occurs in the smaller and more domesticated breeds; in which cultivation has wrought such an entire change of their nature, that even their symptomatic appearances under disease arc, in a great degree, altered by it. O \ 212 RABIES CANINA, tion to pick up straws, thread, paper, or other small objects1^ In others, the first symptom noticed, is an eager and unceasing attempt to lick the anus or parts of generation of another dog20. The lapping of their own urine is a common and early symptom of madness, and one that should be particularly inquired for ; as, when found to exist, I know of none that should be regarded as more strongly characteristic of rabies, and of no other complaint. Some shew an early disposition to lick every thing cold about them, as iron, stone, &c. These, and other peculiarities, often appear in lap-dogs, and others that are under immediate obser- vation, one, two, or even three days before the more decisive and active symptoms. The eyes, even in this early stage, if observed attentively, will often be found rather more bright, lively, and red than usual ; and are then accompanied with a certain quickness and irritability of manner21. In other cases, the eyes are less vivid ; and, more particularly, when the disease is to assume the mild form, called dumb madness, they often present a dull aspect, and a purulent discharge from the inner angles ; occasionally the nose also throws out pus. The salivary discharge is often in- creased early in the complaint, and so coutinues : in other cases, a parched dry tongue is seen, with insatiable thirst. The puru- lent discharge has occasioned the disease to be mistaken for dis- temper. Much stress is laid on a sullen manner, and a disposi- >» I have repeatedly seen dogs, which, before they became at all suspected of madness, had for a day or two industriously employed themselves in this way, so that not the smallest loose object of any kind remained on the floor, to the no small surprise of the owners. a° In one instance, I foretold the approach of the disease by the uncommon attachment of a pug puppy to a kitten, which he was continually licking; as he also did the cold nose of another pug that was with him: and Deane, Earl Fitzwil- liam's huntsman, observes, that among his hounds, he regards the smelling and licking of the penis and fundament of another as a most suspicious symptom. It is a curious circumstance, that sexual excitement is frequently an early symptom in all the subjects of rabies. It has been seen in the human; and rabid sheep are usually observed to first shew the disease by riding their fellows. 21 Mr. Youatt expresses this alteration in the eyes as being of a peculiarly bright and dazzling kind, accompanied by a slight strabismus; not the protru- sion of the membrana nictitans, as in distemper, but an actual distortion from the natural axis of the eye. OR CANINE MADNESS. 213 t ion to hide or retreat from observation, as early characteristics of madness ; and these appearances are certainly not unusual in hounds and kennelled dogs, but they are less frequently observed in the petted kinds : this, however, will greatly depend on the gene- ral character of the dog at all times. Costiveness is not uncommon in the incipient stage ; in the latter it is still more frequent. An early sickness and vomiting often appear, but although ineffectual retchings may continue, actual vomition does not often accompany the complaint through its progress ; the peculiarity of the inflam- mation in the stomach rather tends to retain the ingesta within it. Indeed, this circumstance forms one of the strongest criteria of the existence of the disease, as will be hereafter noticed. A continual licking, or violent scratching of some particular part of the body, is by no means an uncommon symptom ; and a close examination of the part will frequently detect a scar, or the remains of the wound by which the poison was received ; and when the former wound cannot be ascertained in this way, if a true history of the case can be gained, it will always be found that the inoculation was received on the part so scratched or licked ; for I have reason to believe that this morbid sympathy in the bitten part exists more or less in every case1. The appetite is by no means always affected in either early or continued rabies ; on the contrary, food is not only eaten, but digested also, during the first stages ; and some will eat almost to the last, but with them the food is seldom digested. That no disinclination to liquids exists, will be readily acknowledged by all who observe the dis- ease with only common attention : from the first to the last, no aversion to water is ever observed. In the early stages, liquids are taken as usual, and some continue to take them so throughout 1 I have seen a dog which had been known to have been bitten in the foot, some weeks afterwards begin to lick the part, at first gently, then violently, in- cessantly whining over it, as though distressed with the sensation produced, until, at last, he has proceeded actually to gnaw it. I have witnessed the same on other parts, as the lips and ears, which have been rubbed or scratched with anxious perseverance from the beginning to nearly the end of the complaint, when the rabid bites have been received there. o 2 214 R A HIES CANINA, the complaint ; others cannot, from a swelling and paralysis of the parts of deglutition, readily swallow them in the advanced stages ; but, in such, no spasm is occasioned by the attempt, nor does it cause pain or dread: on the contrary, from the thirst brought on by the symptomatic fever present, water is sought for, and, in most cases, an extreme eagerness is expressed for it2. 2 It is imperative on me to press this point particularly, as will be seen be- low. Mr. Youatt also expressly says in Ms pamphlet, p. 3, "There is no dread of water; no spasm attending the effort to swallow; but a most extraordinary and unquenchable thirst." Mr. Meynell remarks, that mad dogs have no abhor- rence or dread of water; and that they will eagerly lap it even the day before their death. He also notices the paralysis that often renders their attempts to drink abortive. John Hunter, who was not accustomed to state facts without examination, says, that " mad dogs can swallow solids and liquids through the whole disease." Trans, of a Society for the Improvement of Medical Know- ledge, p. 296. Dr. Hamilton also has, " A rabid dog never avoids water, and laps whatever liquid food is set before him, long after the poison can be com- municated by his bite." — Remarks on Hydrophobia, vol. i, p. 12-16. " Cette chienne, avoit bu et mange1 apres avoir inordu." — Journal de Midecine, vol. xxxix. " Le loup mangeoit tranquillement une chevre, et celui de Frejus traversa plusieurs fois de grandes rivieres a la nage." — Voy. d'Arluc, Recueil Periodique, vol. iv. " II est done dangereux de concleur de ce qu'un animal bait et mange et traverse une rivUre, qu'il n'est point atteint de la rage." — TroUiet, Nov. Trait, de la Rage, p. 276. It is incalculable the mischief that this sad but too common prejudice has pro- duced ; it has rendered thousands of persons miserable for months and years even, while others it has lulled into a fatal security. Should a dog, from an affection of any kind soever, be prevented from swallowing, he is immediately pronounced mad, and is unreluctantly destroyed; while dread probably remains in the mind of every one who has even been within his reach. An unfortunate person, who may have been bitten by this same dog, for months or even years before, is not exempt from the panic ; for, among other popular errors that are current, is, that if a dog becomes mad, any person, who may have been former!; bitten by the animal, is equally in danger, as though it had happened when the animal was really affected. On the other hand, if a sick dog can drink, he is pro- nounced free from all danger of madness; and so universal has this opinion been, that Dr. H., an eminent physician now in very extensive practice in the western part of London, on being consulted by a person actually bitten by a rabid dog, immediately inquired whether the dog by which he had been wounded could drink ; and, on being informed that he could drink, he peremptorily pro- nounced that the dog could not be mad ; and proceeded to recommend that no precautions whatever should be made use of. This gentleman was guilty of a piece of professional presumption and ignorance unworthy of his rank and situa- tion; and his advice, had it been followed, might have caused the death of three persons. Fortunately for them, his opinion was not attended to, and I disserted OR CANINE MADNESS. 215 The experience of more than twenty years, many of which were passed in the midst of its most frightful visitations, I again re- peat did not produce one instance where any thing like a dread of water was manifested, or any where spasm followed the at- tempts to take it. I have already hinted at an early and marked alteration of the temper of the animal, as common; something of it may be seen in almost all cases. I say almost, because occasionally, and par- ticularly in the dumb variety of the disease, it is altogether want- ing ; and which phenomena is most common in the lap-dog breeds, and particularly in pugs. The degree of irritability varies much, according to the variety of the disease, it being greatest in acute rabies : it is likewise much influenced by the general character and kind of the dog — one naturally ferocious is therefore ren- dered more so by it ; and as might be expected, the fighting breeds usually have it strongly marked, particularly all sporting terriers. In hounds, setters, pointers, &c, the degree of mis- chievous excitement is regulated greatly by the general temper of the dog, and whether it be the dumb or raging kind of the disease. As a general principle, it appears with little ferocity in all dogs in a state of close domestication, and more particularly so towards those to whom the dog has been accustomed to yield obedience. This, however, like all the other symptoms, is liable to variations ; but, generally, these remarks will be found to apply. The change of temper in its early stages consists rather of a pettish irritability the wounded parts out of each of them. In five weeks, an unfortunate spaniel, who had been bitten by this same dog, became rabid; and in six weeks ahorse, bitten by him, became so likewise. Dr. Oilman relates a case of hydrophobia where a fatal insecurity had been indulged in, from the circumstance that the dog both ate and drank during his complaint, Mr. Youatt had a dog brought to him which was unquestionably rabid. The owner, a poor woman, had her hands excoriated by a breaking out, and these hands the dog had repeatedly licked during his illness. On Mr. Youatt's intimation that it was necessary she should use some precaution, she applied to a medical gentleman, who assured her, that if the dog attempted to drink he was not mad, and no precautions were necessary. This opinion was likewise confirmed by another person who pre- tends to some veterinary knowledge: fortunately for her, Mr. Youatt unde- ceived her, and, I believe, applied the preventive. 216 RABIES CANINA, than one of settled mischievous intention ; but, with few exceptions, a marked impatience of restraint is manifested. The first offen- sive symptoms are often directed towards cats, while dogs remain unmolested : next, however, dogs, particularly strange ones, are attacked, but those they are habituated to are still safe; and as the complaint gains ground, even these are not spared. — We will now further pursue the disease under its two leading varieties, which distinctions are founded principally on the cir- cumstance, of whether it spends its violence on the respiratory or on the digestive systems of organs: previously, however, observing, that this distinction is rather made in obedience to popular and long received opinion, which has recognized canine madness as of two kinds, one raging, and the other dumb, than to any specific difference between them : on the contrary, when the attack is equally diffused throughout the system, the symptoms of these two states are so blended, as to afford little room for noso- logical distinction ; and the less, as each variety begets either the one or the other indiscriminately. Nevertheless, as the attack on the organs is rather partial than general, in the majority of cases, so it may not be inconvenient to follow the popular dis- tinctions. Acute or Raging Rabies. Acute Rabies, or Raging Madness3, as it is called, is that state of increased excitement and irritability which begins to shew itself immediately after, and occasionally only with the early symptoms. Sometimes these precursors are passed over un- noticed, and it is therefore supposed that the animal is at once attacked with the appearances that follow. It is, however, very seldom that such is really the case, by which the danger from It is a curious fact, but it is no less true than curious, that the rabies of very young dogs, as I have seen it, has always been of this kind. I never saw arabrd puppy that did not exhibit marks of considerable delirium and much mis- chievous tendency towards every living being, indiscriminately. That affection of lire throat, and tu Faction of the parts of deglutition, producing dumb mad- ness, I never met with in any but an adult dog. OR CANINE MADNESS. 217 madness is much lessened. The acute or raging kind is distin- guished by a general quickness of manner, sudden startings, great watchfulness, and a disposition to be acted on by sudden im- pressions, as noises, the appearance of a stranger, &c. This watchfulness, however, often yields to a momentary stupor, and inclination to doze, from which the dog will start up, and fix his eyes stedfastly on some object, probably on one not usually noticed, and often on one altogether imaginary ; at which he will attempt to fly. In this stage the breathing is often hurried ; sometimes the panting is excessive, and, where the pulse can be examined, it is invariably found rapid and sometimes hard. The irritabibty in these cases is marked by extreme impatience of controul ; and even when no aptitude to attack or act offensively towards those around may appear, yet a great disposition to resist any slight offence offered, commonly shews itself. A stick held to such a dog is sure to excite his anger, even from those he is most attached to, and he will seize and shake it with violence : the same will occur if either the hand or foot be held out, but, unless in a very great state of excitement, these he will rather mumble than tear, if belonging to those he is acquainted with. This disposition to become irritated on the slightest shew of offence, as flying at a stick, is a very marked feature of rabies, and should be very particularly attended to, and the more, as it usually is present in both varieties of the malady ; unless when paralysis has blunted the capability of excitement. A peculiar suspicion marks these particular cases, and a degree of treachery also, by which, in the midst of caresses apparently received with pleasure, the dog will at once turn and snap at those noticing him : he will, perhaps, readily come when he is called, and with every mark of tractability will wag his tail and seem pleased, but on a sudden he will seem to receive a counter impression, and hastily bite the person who called him. This stage is often marked, in large and naturally fierce dogs, with an utter fearless- ness of danger, and contempt of every menace : every restraint is most unwillingly submitted to ; the miserable brute shakes his 218 RABIES CANINA, chain with extreme violence, and, when confined without one, lie will attempt hy every means to escape, and will force or gnaw his way out of his confinement, in a most surprising manner. The vessels that are placed before him he overturns or breaks with mischievous alertness. A disposition to rove accompanies each variety of rabies ; but as, in the dumb kinds, the paralysis, stupor, and prostration of strength, are hindrances to it, so it is more particularly apparent in the acute kind. This inclination does not usually shew itselt by an attempt to escape altogether, neither does it appear a de- lirious affection ; on the contrary, much method is displayed in it, which makes it rather seem an instinctive disposition common to all, to propagate the disease. In its early stages, before the strength is much impaired, dogs will travel immense distauces under this impulse: such a one trots along, and industriously looks out for every other dog within his reach or sight. When- ever he discovers one, little or large, he first smells to him, in the usual way of dogs, and then immediately falls on him, generally giving him one shake only ; after which, he commonly sets ofi' again in search of another object. The quickness with which this attack is made very frequently surprises the bitten dog so much, as to prevent his immediately resenting it: but nothiug is more erroneous than the supposition, that a healthy dog in- stinctively knows a rabid or mad one. I have watched these attacks in numerous cases, and 1 have seen the mad dog tumbled over and over, without the least hesitation, by others that he had himself fallen on. During this march of mischief, rabid dogs but seldom, how- ever, turn out of the way to bite human passengers : neither do they so often attack horses, or other animals, as their own species. Sometimes they will not go out of their line of travel to attack these even ; but, trotting leisurely along, will bite only those which fall immediately in their way. In other cases, however, where the natural habit is irritable and ferocious, and where dogs may have been used to worry other animals, as guard-dogs, fanners' OH CANINE MADNESS. 219 dogs, terriers, &c, a disposition to general attack is sometimes apparent; and by such, horses, cows, sheep, pigs, and even human persons, are all indiscriminately bitten. When such a dog has roved about for an indeterminate period, as ten or even twenty hours, he will return home quietly, if not discovered and destroyed in his progress1. The affection of the larynx produces an invariable alteration in the voice, and a very marked one it usually is. A few are altogether mute, from engorgement of the parts. The sounds emitted of themselves form a strong characteristic of the com- plaint. In the irritable variety, the alteration is first observed by a more quick and hasty method of barking, with some dif- ference also in the usual tones of the bark ; by degrees, an occa- sional howl either follows the bark, or takes place of it alto- gether5. This howl, which is common to both varieties of the complaint, in the dumb kind has a choaking hoarseness with it: the whole however is of so peculiar a hind, that it may be said never to be heard under any other circumstance than from a rabid dog6. 4 In cities and large towns this return after a march of mischief is sufficiently common; but in the country it is different, and, therefore, this peculiarity has not an opportunity to shew itself; for there the unfortunate animal is sooir detected by his maimer, and is infmediately hunted. If not overtaken, he is too much alarmed to return soon ; and, before he has time to recover his fright, he is discovered in some other situation, and falls a sacritice to the anger of his pursuers. The very hunting will, of course, do to him what it would to any other dog ; it will beget fury : otherwise there would very seldom be much ferocity apparent, and, in most instances, such a dog would return home when thoroughly tired. 5 It is evident, that it is not easy to form a written description of any pecu- liarity of voice, but the rabid howl may not unaptly be resembled to the tones produced by what is called, among sportsmen, the giving longve of the old heavy southern barrier. It appears composed of something between a bark and a bowl, being made up of loin s longer than the one and shorter than the oilier, and always with the head thrown up; and is usually single and repeated at uncertain intervals only, and is altogether so peculiar, that, when once heard, it can never be forgotten ; and so characteristic, that it may be, I may Bay, implicitly relied on. I have, in several instances, been attracted to bouses Where dogs have been confined by the sound alone, in time to warn the inha- bitants of their danger. 6 Boerhaavc seems to have this howl in view, when he says, " Jiutti quoad latraluin, munnurautcs tanicn." 220 RABIES CANINA, The Taciturn Rabies. Dumb madness forms the other and most frequent variety in adult dogs, and which cases appear dependent on a less degree of active sensorial excitement, but with greater morbid affection of the bowels. Tlie symptoms which succeed to the premonitory ones, are often rapid ; and superadded to the dull, heavy, and distressed countenance, costiveness, &c, there appears a stiffness about the jaws, and a hollow sound is emitted in breathing which is rather performed by the mouth than the nose, that being plugged up with pus, or the arch of communication being straightened by tumefaction. As the whole of the pharynx and larynx becomes tumefied to the full extent, the muscles at the base of the tongue, and those of the lower jaw, are l'endered inert; the mouth remains open, and the tongue hangs pendulous with- out it ; and sometimes an actual inability to wholly close the jaws takes place altogether. A congestion of blood is the necessary consequence of the distention of the parts, and the tongue from this cause usually appears, in these cases, livid or almost black, particularly towards its apex or point: frequently a black line extends through its whole length. This state of the parts occasions often a difficulty, sometimes a total inability even, to swallow either liquids or solids. In general, however, the ina- bility is principally confined to liquids, which are, in such in- stances, returned as fast as they are lapped, from the incapacity of the tongue to carry it into the pharynx ; but in no instance, as already insisted on, do the attempts to swallow appear to excite apprehension or give pain. The mouth itself is mostly parched and dry ; occasionally it is moist, with saliva continually flowing from it?. It is the tumefaction of the pharynx that produces the deep choaking noise already noticed, and which seems to issue from the bottom of the glottis : all the ordinary 1 Inmost cases an increased salivary flow arises at some period ot the com- plaint, which is not frequently lasting, but is succeeded by a viscid br, ochia] se- cretion, that appears to irritate the dog beyond endurance ; and to remove which, he often employs himself with the utmost violence, by forcing his paws against his mouth, as dogs do when a bone is lodged between the teeth. Oil CANINE MADNESS. 221 symptoms spring from this specific laryngitis and bronchitis, by which these parts are tumefied even to paralysis, yet are totally without any of the human spasmodic rigors. It is however far otherwise with the external muscular tissues: the cutaneous muscles become often first affected, twitchings pass over the face, and afterwards the spasmodic and paralytic affection often extends also to all the organs of locomotion : in others, however, it is principally confined to the loins and hinder extremities. When the morbid affection acts very strongly on the bowels, it often occasions the hinder parts to be drawn forward by a species of tetanic spasm toward the fore parts, so as to bend the poor sufferer into a circle ; sometimes it fixes the animal on his rump, almost upright. A symptom common to this variety, and not uncommon in the other also, is a disposition to carry straw, litter, or other matters, about in the mouth, which the dog seems to make a bed of, frequently altering it, pulling it to pieces and again remaking it. It is also very common to observe dogs scratch their litter under them with their fore feet, not as when making their beds, but evidently to press the straw or litter to the belly. This pecu- liarity appears to arise from some particular sympathy with the intestines, which, in these cases, are always after death observed to be very highly inflamed. There is also present a disposition to pick up and to swallow, when not prevented by the affection of the throat, indigestible and unnatural substances, selected from whatever is around them, and which the costiveness usually present tends to retain within the body. It appears to be this impulse, likewise, that leads rabid dogs to gnaw boards, or what- ever is within their reach ; and this aptitude may be considered as common to every variety of the complaint, except, as already observed, where the tumefaction and paralysis of the throat are so extreme as altogether to prevent it. The irritability attendant on dumb madness is even subject to more variation than in that called the raging. It is sometimes considerable, and exhibits all the treacherous and mischievous *«s* RABIES CAN IN A, disposition that marks the other ; but when the dumb character is strongly marked, there is then seldom either much irritability or delirium apparent ; on the contrary, in many instances, a most peaceable disposition is manifest, and which does not appear dependent on the inability to bite, but really from a total want of inclination to it. Indeed, in many cases of this kind, the tractability of character and mildness of disposition have ap- peared to be even increased by the disease, and that to a degree that will not permit strangers to suppose it possible for rabies to be present. It would sensibly affect any one, to witness the earnest imploring look I have often seen from the unhappy sufferers under this dreadful malady. The strongest attachment has been manifested to those around during their utmost suffer- ings ; and the parched tongue, as 1 have before noticed, has been carried over the hands and feet of those who noticed them, with more than usual fondness. This disposition has conti- nued to the last moment of life, in many cases, without one manifestation of any inclination to bite, or to do the smallest harm. I have observed this particularly in pugs, and it has not been uncommon also in other lap-dogs. The progress of the disease in its latter stages is mai-ked by increased paralysis, and it often happens, as it extends over the body, that of the jaws lessens : the wretched animal now reels about with little consciousness; tumbles and gets up again; now seats himself folded on his rump, and in this posture life is stolen away often without a struggle. The fatal termination ranges between the third and seventh days ; few die sooner than the third day, and very few survive longer than the seventh : the average number die on the fourth and fifth. In man, it has destroyed at the end of twenty-four hours ; few have lasted be- yond the third day: by repeated bleedings, however, a case which is related in The Lancet of July 12th, was protracted to the fourteenth day. Horses do not survive beyond the third or fourth ; the ox and sheep, Mr. Youatt says, from five to seven days; but a rabid sheep, the property of Mr. Adam, of Mount OR CANINE MADNESS. 223 Nod, Streatham, died on the third ; and I have a recollection of one or two others which did not survive longer. What other canine diseases may by possibility be confounded with rabies?- The importance of the subject makes such an inquiry necessary ; but it must be prosecuted in a note below8 ; 8 Thousands of innocent dogs have been sacrificed to mistaking this disease for some other; and thousands of persons have been rendered miserable in their minds by needless fears from the same errors. I know not the numbers of epileptic dogs which have been killed under a supposition of their being rabid; and on the other hand, not unfrequently dogs really rabid have been fondled, and had remedies administered to them, at great personal risk, from a supposition that they laboured under some other complaint. Epileptic Jits, whether occasional or the consequence of distemper, are often mistaken for rabies: but it should be remembered, that there is no rabid symptom whatever that at all resembles a fit, whether in the irritable or in the dumb variety. All epileptic fit is sudden; it completely bewilders the dog, and after a determinate period leaves him perfectly sensible, and not at all irritable, but exactly as he was before: in rabies there is no fit, no loss of recollection, no tumbling about wildly in convulsion ; neither is there any marked break in the natural irritability attendant on rabies. If a dog in an epileptic fit should be so convulsed as to attempt to bite, it is evidently done without design; his attack is spasmodic, and pain may make him seize any thing, and it is quite as likely to be himself as anything beside. The irritability and . mischievous attempts of the rabid dog have always method with them, and they evidently result from a mental purpose to do evil. The mad dog has usually a disposi- tion to rove, the distempered one never. A puppy in distemper, particularly if he have worms, may pick up stones, or eat coals, or he may in a trifling degree take unusual matters as food; yet no dog but, a rabid one will take in hay, or wood, or rag, or will distend his stomach almost to bursting. The discharge from the nose and eyes which sometimes occurs in rabies, I have often see n mistaken for distemper, and that even by veterinary surgeons: it is, indeed, the most deceitful of all the appearances which occur, particularly where it continues for some time, as is occasionally the case. Usually, however, it is the permanent attendant on distemper, and a temporary one only of rabies: while the previous emaciation, cough, and gradual increase of the flow, from thin and watery to muco-purulent, and then to pus, are distinguishing symptoms of distemper. A tetanic attack has been mistaken for rabies; but the extreme rarity of this disease renders such error not of very likely occurrence, and the medical attendant will never be deceived : rigid convulsions may contort the frame, and close the mouth ; but there is no other likeness to rabies present, and the dog is as incapable as he is disinclined to do mischief in any way: the death of the tetanic dog will also, by internal inspection of the body, at once distinguish between these diseases, as in tetanus there are few marks of visceral disturbance. Spasmodic colic will contort the dog, and may sometimes make hnn irritable and disposed to bite, if he be disturbed: but he will never atte t it purposely: on the contrary, he will rather avoid all intercourse with living 224 RABIES CANINA, it being desirable that the thread of the detail should be unin- terrupted and uniform in the text. Post-mortem Appearances. The morbid anatomy of the rabid dog forms a most important feature in a portrait of the malady, but is one that was long neglected. It by no means unfrequently happens, that it is not until after a dog is dead that he is suspected of having been rabid, although he may have bitten one or more persons. Under such circumstances, it is evident that it is of the utmost con- sequence to be able to decide, from an inspection of the dead body alone, whether the disease did or did not exist. Fortu- nately the morbid appearances peculiar to these cases are usually so marked, and so prevalent, that a just decision is seldom dif- ficult to form, even from them alone. On a careful examination of the head, the brain and its mem- branes will be usually found to have suffered more or less from the attack. Sometimes the general vascularity is only slightly increased, but, in most, the vessels of the pia mater will be found distended with blood, and usually in the degree of excitement exhibited, but in no instance have I observed the membranes thickened, as in idiopathic phrenitis. The inflammatory appear- ances within the cerebral cavity are usually less considerable in those cases called dumb madness. As might be expected, the spinal brain, or spinal marrow, as it is called, usually partici- beings. Colic also, particularly that occasioned by taking lead internally, pro- duces excruciating pains not present in rabies, which pains also remit and return atuncertain intervals: again, although plaintive moans may be heard in spas- modic colic, barking or howling is always absent; neither are the jaws para- lyzed : active purging also relieves this, but is totally inert in the other. Lastly, the mistakes likely to occur between rabies and other diseases are, in some de- gree, attributable to erroneous pictures drawn by authors of such diseases: thus, Dr. Jenner's account of the distemper, instead of deserving the praise his great name has drawn down upon it, is entirely calculated to mislead: indeed, il might be supposed by his readers, that he was purposely describing rabies and not distemper.— See Medico-Chirurg. Trans, vol. i, p. 263. I could produce many similar instances in other authors.

The membranes of it are often highly injected^ the canal likewise is suffused with fluid, and the nervous column itself presents diseased appearances. — Journal Vniversel des Sciences Mhdicales, torn. 65, 134e colder. Much of the general tumefaction which existed during life about the back of the mouth, disappears on the collapse of death, but it commonly leaves the base of the tongue and the sublingual glands enlarged and injected as well. Mr. Youatt has often, he observes, found the parotid and submaxillary glands gorged also. As regards the tongue, not only its base generally remains tume- fied, but its papillae are particularly enlarged, as also the mucous glands of the under surfaces, which have been the subject of critical examination of late years ; and which Mr. Youatt, with much probability, thinks have been mistaken by Marochetti and others for his famed pustules. It is also important to be aware, that whether a dog has been wormed, or not wormed, no dif- ference whatever is found in the appearance of the under surface of the tongue : if the frenulum is present, that portion is not in any degree particularly swollen or red ; and if it have been ex- tracted, the general appearances are exactly the same. This will be further pursued under the head Worming of Dogs ; but it is of much consequence, that this invariable similarity in morbid ap- pearance between the wormed and the unwormed dog, be espe- cially noted. The colour of the tongue betrays the intensity of the inflammation which has pervaded it, varying from a dark red to a deep purple; a yellow central line sometimes presenting, and occasionally bounding its edges. The fauces and tonsils never 9 " L'encephale oflfrait une injection sensible du reseau vasculaire qui le forme en partie; l'arachrioicle etait aussi fortement injectcie; Ies hemispheres ctSre- braux presentaient a leur surface un (Spanchement de sang assez considerable ; a la coupe, ils laissaient transsuder des gouttelettes de sang.

The whole extent of the pharyngeal and laryngeal cavities is mostly beset with discoloured spots ; but a distinct inflammatory patch about the angle of the larynx, at the back of the epiglottis, is so invariably present, as to deserve the character of one of the criteria of the disease. The epiglottis and rima glottis are also commonly enveloped with an inflammatory tinge, which, now and then, extends a little way within the trachea, but less frequently is the oesophagus affected with it. Proceeding onwards, we inva- riably meet with an extension of the morbid inflammation to the thoracic and abdominal viscera: but by no means are these cavi- ties always affected in an equal degree ; on the contrary, in those instances where there has been a greater tendency to the raging variety, the thoracic viscera are usually more diseased than the bowels or stomach. Not only are the lungs themselves, in these cases, found highly inflamed, but the costal pleura and diaphragm are affected also. Sometimes one thoracic cavity is found more hio-hly congested than the other ; and, now and then, the medias- tinum, pericardium, and even the heart itself, in cases of great rabid intensity, are found so likewise. When the abdominal viscera are examined, they almost inva- riably present marks of a full share of the morbid affection. If the dog has been destroyed early in the disease, these may not be very considerable, and an occasional case may occur where the appearances are not very strong, even when the annual is suffer- ed to remain until death; but such instances are rare. In the stomach inflammatory marks are very seldom wanting; and turning our attention to a rabid one, we are often first struck with its appearance of distention, and on opening it, the cause is seen to arise from an accumulation of a considerable, oftentimes of an immense, mass, of indigestible substances, as hay straw, wood, coals, or, in fact, of any surrounding substance which has proved small enough for deglutition. This disposition to take ... OR CANINE MADNESS. 227 unusual ingesta exists in every variety of the complaint ; and as sickness and vomiting, though common in its early stages, are but seldom to be found during the latter periods of it, so the sub- stances taken in being of an indigestible nature, necessarily re- main witbin the stomach until death. There is little reason to doubt that a morbid sympathy in this organ is the occasion of this peculiarity, and that the presence of these hard bodies gives some reHef, probably by the distention they occasion. Certain it is, that the appearance of this indigestible and incongruous matter within the stomach is so common, that it becomes a pathogno- monic sign of the utmost importance, and it should be searched for in every case where doubt exists10. When the stomach is emptied, it usually presents marks of very intense inflammation. If the dog has been destroyed very early in the complaint, the inflammatory markings may not be very considerable, but, in every such instance even, which has ,0 In describing the criteria of the disease, 1 have purposely omitted before enlarging on this particular, that I might here do it more fully, and that I might at once describe both the cause and effect: I must now there- fore remark, that, of all the characteristic marks of the complaint, I consider this as the most genuine, and as the one liable to the least variation. I will not say that I never saw a rabid stomach, after death, without this crude indigestible mass ; but, during the examination of more than two hundred cases, I do not recollect to have met with but very few indeed in which there has not been either this, or a chocolate-coloured fluid : and when these indigesta are not present, on inquiry it will still be often found that such have been vomited up. This genuine characteristic cannot, there- fore, be too strongly kept in mind, because it is one that may be sought for by one person as well as another, by the most uninformed, and by the ama- teur, as well as the professional man. It is also more important, because it may be found long after death, when the other marks have become blended in the universal decomposition and decay of the body. I cannot exemplify this better than by relating a circumstance of my being sent for, to a considerable distance" in the country, to examine a suspected dog, who had been already buried three n eeks, but was now dug up for my inspection. All other marks to be gained from the morbid anatomy had, of course, disappeared ; and 1 must have been left in doubt (for the dog had come some distance, had bitten a child who was caressing him, and had been in consequence killed on the spot; nothing, therefore, of his history was known), had it not been for this unfailing crite- rion, which I found to exist, in this instance, in its full force, and (nun which I was led, without fear of error, to decide that the dog had been rabjd. P 228 RABIES CAN IN A, fallen under my notice, in some degree or other, they have still been present ; while, in those cases where the animals had been suffered to die of the disease, I never remember one in which the morbid appearances were not considerable. The inner surface, or rugous coat, is often livid, and not unfrequently sprinkled over with pustular prominences : it is not unusual, likewise, for it to exhibit sphacelated ulcerous patches. I have seen it actually per- forated by the mortification present. The outer surface is seldom wholly free from inflammatory marks either, particularly along the great curvature ; and such is the intensity of the inflamma- tion, that T have seen blood extravasated between the mem- branous and muscular coats. There are seldom many fluid con- tents present,— the mass of iugesta usually absorbs what may be there ; but when any such are found, they invariably consist of a dark-coloured liquor, not unlike coffee grounds. The intestinal tube is often found with strong marks of disease also ; but the frequency of these is not equal to the stomachic af- fection. It is seldom continuous, but rather in contiguous patches, principally affecting sometimes one and sometimes another of the intestines. The villous surface is frequently gangrenous, and the outer or peritoneal portion, from the coagulable lymph thrown out, is often found adhering to other portions. Sometimes intus- susception exists, but constrictions and twistings are still more frequently present. Occasionally, the tube is altogether empty, but it is more frequently found partially distended with hardened feces, and not unfrequently with worms. The degree of inflam- mation between the stomach and intestines is not always corre- spondent ; on the contrary, when the one has been very highly in- flamed, it has not been unusual to find the other less so, but variations in the state of the stomach are less frequent than those in the bowels. I have usually found, when the appearances of this symptomatic enteritis have been intense, that such cases, during life, had exhibited torpor, distress of countenance, affec- tion of the parts of deglutition, great scratching of straw to the belly, paralysis, and all those characteristics more immediately OR CANINE MADNESS. 229 appertaining to what is called, by sportsmen, dumb madness. On the contrary, when the intestines have been but little inflamed, and the stomach likewise not intensely affected either, but the lungs extremely so ; such cases, during life, have been charac- terized by great irritability, a desire to rove, and those appear- ances common to raging madness. Mr. Youatt seems not to have met with many cases of very intense intestinal affection : but when I was familiar with it some years ago, the bowels some- times exhibited the principal share of inflammatory violence. Se- veral notices of this kind, made on the intestinal morbid marks, are now before me. One dated 1812, states, that a dog, the pro- perty of the Duke of Sussex, which I was requested to see, gave unequivocal signs of rabies, of which he died. When opened, the stomach was but little inflamed, but the intestinal tube through- out, particularly the stomachic half, was gangrenous, and exhi- bited intussusception in various parts: Great marks of intesti- nal inflammation are noticed by Dr. Gilman, and by many of the French writers who have given the post-mortem examination. The remaining abdominal viscera are often found to participate in the affection. The mesentery is sometimes seen clotted with grumous spots, and adhesions are formed between the parts from the coagulable lymph thrown out. The liver, pancreas, spleen, and omentum, but particularly the former, are often inflamed. The kidneys usually escape, neither is the bladder in general at- tacked, but the urine contained is often deeply tinged with bile from the hepatic affection. The bodies of those dogs, who die of this disease, soon become putrid ; but there is no peculiarity of smell attending them : neither are they so offensive as I have often witnessed them in other cases of inflamed bowels, particularly of that kind produced by mineral poisons. I have frequently offered to a healthy dog various parts of the body of rabid dogs, but I could never dis- tinguish any marks of dread or disgust ; I am, therefore, con- vinced that, living or dead, there is nothing in the smell that p 2 230 RABIES CANINA, characterizes rabies from one to the other, as has been so often alleged, among the other vulgar errors held forth. Inquiry into the Morbid Action op the Rabid Virus. Having already endeavoured to shew that the rabid poison is onlv received into the system by the actual insertion of it by means of an abraded surface, it will now be our endeavour to in- quire its modus operandi when received there. This subject has occasioned a diversity of opinions ; one of which is, that the rabid virus is at once mixed with the blood by the absorption of the lymphatic vessels, and that it afterwards exerts its morbid agency principally on the nervous system, and on other parts sympathetically. I long entertained an opinion that the rabid poison entered the circulation as soon, probably, as it was received, exactly in the same manner with the poisons of venomous reptiles and other morbillse. Some sympathy, however, seems to be kept up with the bitten part, without the agency of which the virus can never germinate into fatal action. The wound, therefore, when first received, not being under the immediate action of the morbid matter, heals as other common wounds ; but, after an un - certain period, a secondary and lymphatic inflammation arises within the part, a new morbid compound is formed, and all the symptomatic appearances which follow are derived from the ab- sorption of this newly generated poison. The most popular opi- nion, however, of the day is, that which considers the virus re- ceived, as remaining stationary within the wounded part" until n It remains perfectly undecomposed. The absorbents are actively at work i„ removing every thing around. The capillary vessels are depostting fre h L t but it seems to remain the same. Whatever else is use ess or would be h juHous, is taken up, and the tissue or the fibril on winch .ho v.ru, res is modified or changed; but this extraneous and fatal body bids defiance o a .' he powers of nature. It enters not into the circulation or ,t would ne- cessarily undergo some modification in its passage through the ■ able m^ vessels and glandular bodies which are scattered through the frame It 3d excite some morbid action; or if it Were not thus employed, or ,n the OR CANINE MADNESS. 231 it is excited into action by some irritation in such part ; from whence it is carried along the sensible and irritable fibre to exert a particular morbid action on certain organs ; to all appearance, on the sensorium itself: for the sensations which arise in the bitten part, as an invariable precursor to other morbid phenomena, follow the course of the nerves, rather than of the absorbents ; and we do really find the first constitutional symptoms are of nervous origin. Our principal authorities, I believe, unite in con- sidering it as a disease of the respiratory nerves, principally ex- pending itself on the cervical, dorsal, and lumbar portions of the spinal column ; and such I believe it to be altogether, in the hu- man subject : intrinsically, it may be so in the brute constitution also (as Dr. Clutterbuck would ingeniously derive every fever from inflammation of the brain) ; but in the brute subject I am disposed to think it unites itself with a specific phlegmasia, little known to the human12. purposes of renovation or nutrition, it would be speedily ejected. It lies for an uncertain period dormant; but at length, from its constant presence as a foreign body, it may have rendered the tissue or nervous fibril more irritable and sus- ceptible of impression; or it may have attracted and assimilated to itself ele- ments from the fluids that circulated around it." — Pamphlet on Rabies, p. 25. Whatever are the principles of its action, the surrounding parts evince the pre- sence of a stimulus, which usually first shews itself in the general texture by slight inflammation, attended often with intolerable itching in the dog, which is betokened by that constant licking and even gnawing of the bitten part, which has been noticed as a common symptom of rabies in that animal. In the human, this first acknowledgment of the incipient action is also, 1 believe, invariably present : in Mrs. Duff's case, a pimple first appeared on her nose, being the spot which a favourite Newfoundland dog had scratched and then licked, in the com. mencement of his rabid attack. This pimple troubled her by its smarting, itch- ing, and throbbing, three days before the more active symptoms appeared. In Metcalf's case, shooting pains, directed from the hand towards the head, pre- ceded the more active symptoms ; and something of this kind, I believe, would be found to accompany every one, in some degree or other, were the circum- stance particularly attended to. In horses, cattle, and swine, this secondary in- flammation is equally common and even more striking: they will rub, bite, and tear their bitten parts with violence, and in them the local irritation is long kept up after the disease is fully formed. M Mr. Youatt appears to entertain an opinion of the complete identity of the rabid disease in every animal whatever, and consequently in man as the head of them all. He certainly argues the point most ingeniously, it must be owned ; yet the analogy appears rather strained, although, with the above admissions, it 2:32 RABIES CANINA, The Medical Treatment, Curative and Preventive of Rabies. The curative treatment of rabies in the dog has hitherto proved invariably unavailing, neither has it been found other- wise in any other animal ; while the few successful cases on re- cord of a favourable result from any means tried on the human will be hard to deny his premises ; which are such, that it would be doing both the author and the reader injustice to give in any other form than his own. " Rabies," he says, " is a nervous affection, and particularly of the respiratory system of nerves, or those which are employed in the instinctive and involuntary actions connected with respiration, and which serve to associate many of the voluntary muscles in the discharge of the same function. These nerves arise from the medulla oblongata, in which, or on its membranes, inflammation is al- most invariably detected. They do not spring from the same columns with the other spinal nerves; and they have roots peculiarly constructed, and following one another in an uniform line, as if they were leagued in the performance of the same office. They are the portio dura of the seventh pair, distributed over the face; the glosso-pharyngeus, which supplies the pharynx and the tongue; the par vagum, wandering to the pharynx, the larynx, the heart, the lungs, and the stomach; the recurrent, ramifying on the muscles of the larynx, and the membrane of the glottis; and the spinal-accessory given to the neck and shoulder, and reaching even to the loins. The twitchings and contraction of the eyelids, the strabismus, the spasms of the cheek, and lips, and face, and the paralysis of the muscles of the lower jaw, sufficiently prove an affection of the portio dura. The protrusion of the tongue, the enlargement of (he sublingual and other glands, the inability to swallow, and the alteration of the voice, im- plicate the glosso-pharyngeus. The increased circulation, the laborious re- spiration, the peculiar inflammation of the pleura, and the constant and often intense inflammation of the stomach, are attributable to the par vagum. The involuntary barking, the husky grating inspiration, the frequent inflammation of the trachea, the uniform inflammation of some part of the glottis in the quad- ruped ; and the dreadful excitation of the membrane of the glottis, with all the horrors of hydrophobia in the human being, testify that the recurrent nerve lias not escaped: while the hurried and uncertain action of the fore extremities, and the palsy of the region of the loins, are clearly to be traced to the spinal ac- cessory. These nerves anastomose freely with the cerebral nerves, therefore cerebral affection soon occurs. There is a state of general and extreme excita- tion, a very peculiar wandering and delirium, and, in some animals, fits of savage and uncontrollable ferocity. They likewise unite and blend with the ganglionic nerves, and thence proceeds altered secretion ; a morbid secretion of the gastric juice occasioning the strangely perverted appetite of the dog ; and a still more depraved secretion of the saliva, converting that bland and innocuous fluid into the direst poison."

The extent to which this inquiry has already been carried, will prevent a cir- cumstantial detail of the various medicinal agents which have been used as curative of rabies. I shall only cursorily notice them, and reserve myself for those that, fortunately for man and brute, are found efficacious as preventives against such attack; pausing only to observe, that my account will combine both the human and brute treatment, that I may render these pages more extensively useful, as well to the public, as to the practitioner in brute medicine, whose opinion will be often sought for, where the owners of rabid animals have been unfortunately wounded by them. Here, as I have often found, the timely benefit of judicious advice, and even the application of proper preventive means, have gained unbounded gratitude, and a consciousness of being eminently useful. The most ancient remedy on record for the rabid malady, after it had actually appeared, was cold bathing, which it was usual to apply to the extent of a temporary drowning ; but, although it is handed down to us, that it occasionally proved successful, these accounts are not now relied on1*. 1 tried it on two rabid dogs to the extinction of life almost, and it certainly suspended the progress of the complaint for some hours ; which I attribute, not to any specific virtue in the bathing itself, but to the shake given to the constitution : for it is remarkable, that any great vio- lence offered from accidental causes15, during the progress of the 13 "Nec desperandum tamen ob exempla jam in aliis venenis constantia, de inveniendo hujus singular is veneni anlidolo singulari." — Doerhaave, Apho- rism H46. 14 Celsus recommends it, and gives instances of its successful application. Euripides is one who was said to have been cured by it. is During the roving* of a rabid dog, it is to be expected that he will meet with severe beatings from other dogs, and, not unfrequently, he will be subject to violent attacks from human persons, from whom he may, however, eventually escape, although severely handled. I have had many opportunities of observing dogs, after their return, which have been so treated, and I have invariably found RAUIES CANINA, disease, particularly in its early stages, in every instance appears to beget a new action, which, for a time, arrests the progress of the rabid one, and suspends its more active symptoms for a longer or shorter period, usually in proportion to the violence done. The morbid poison, however, soon resumes its ascend- ancy, and the fatal issue is only protracted, but never removed. Warm bathings have been also fully tried, both in ancient and modern times, with no better success. Bleeding largely was an ancient remedy, which has been revived by the moderns ; and on the authority of some reputedly successful cases, but now ques- tioned, I was induced to try it to its fullest extent (ad deliquium) on two or three rabid dogs. Mr. Youatt has done the same, and in every instance with a mitigation of its violence, but in no one of permanent benefit16. It therefore appears to act in these in- stances, as in all others where much violence had been committed on the constitution, by a suspension of the morbid action of the disease. Of electricity and galvanism, as applied for the cure of rabies, I have no experience : it has, however, been fully tried in the human subject without success. Vinegar, which, in Ger- many, was said (but I believe erroneously) to have arrested the human disease, has failed in dogs in every instance in which it has been made use of. Mercury I have also tried to its fullest extent, and in most of its popular forms, without the smallest be- nefit. Camphor and opium, both by the mouth and per ano, have proved equally inert in these cases17. With the belladonna I that an absence of the more active appearances of disease has followed for two or three days ; and that, in some cases, to such a degree as to deceive those around, and make them consider the recovery of the animal as certain; but gradually the complaint has returned with all its violence. 16 M. Gossier, Professor of the Veterinary School of Lyons, also employed bleeding on three dogs to deliquium, .without success. It is, however, to be remembered, that in the human subject it is said to have cured the complaint in one or two instances in India: and in a case related in The Lancet, it protracted the fatal course to the fourteenth day: and though the Asiatic cases are rather doubtful, it has evidently some restraining power. 17 Professor Dupuytren injected opium in solution into the veins of two rabid dogs, but without any alleviation of the symptoms. — Disscri.dc Ch. Busnout, Paris, 1814. OR CANINE MADNESS. succeeded no better ; and the alisma plantago, or water plantain, has proved equally unsuccessful with Mr. Youatt, who however observes, that it usually mitigated the symptoms ; as did also the belladonna. The Scutellaria lateriflora, so highly recom- mended by Dr. Spalding, of New York, Mr. Youatt has not suc- ceeded with ; but he yet considers that it deserves more trial, from the decided effects it produced in the cases on which he tried it. The internal and external exhibition of the volatile alkali has not been more fortunate, although the analogy of its beneficial effects, in cases of poisoning by the bite of the cobra de capello, had raised hopes of its proving useful here also18. Cauterizings, scarifyings, blisterings, &c, have been applied to the bitten part in the human subject after the attack, but without avail. From the known property of arsenic in lessening the spasm of epilepsy, something was hoped from it in the hydro- phobic spasm of the human, but it has not answered the expecta- tions formed. — See Med. Chirurg. Trans., p. 393 ; Lond. Med. Rev. for March and April, 1793. On rabid dogs I have fre- quently tried it, and, from its decided capability, evinced on each trial, of suspending the complaint, I was once also led to hope much from it; but repeated experience has proved that its benefits are not permanent1^ but act only like other violent means. Chlorine has been said to remove the hydrophobic symptoms, but late trials have shewn the fallacy of the assertion. The same has happened to sulphuric acid, with which a Dr. Skuderi pretends to have effected several cures of hydrophobia, by its internal and external administration. More recently also the guaco has been tried on both the human and brute subjects ; but 18 Tissot strongly recommends the eau de luce, and says, " II calma l'agita- tion, occasion un seur abondant et fit disparoitre les symptoms." — Avis au I't uple, torn, i, p. 179, 8vo, Paris. 19 I have given it, in these cases, in very large doses, as five, six, and even a greater number of grains, and have been surprised how little disturbance it seemed to produce; probably from the stomach being already affected with a specific inflammation, by which it was rendered less likely to be acted upon by occasional causes. 236 RABIES CAN1NA, although it had a temporary effect in mitigating the symptoms in both, yet the fatal termination was the same. There is, there- fore, reason to believe that we have no authenticated case of the true rabid malady having yielded to any treatment, either in man or beast, after it had actually made its attack. The preventive treatment. — Here, fortunately for mankind, we stand on 'vantage ground, as we are able, in most cases, by the adoption of judicious means, to insure the safety of the bitten, when we can distinctly ascertain the wounded part; which in brute subjects, it is evident, it is more difficult to do than in the human. The prophylactics, that both interest and ignorance have extolled and brought into use, are innumerable : very few of them, however, have deserved the smallest confidence ; on the contrary, they have lulled into a fatal security those who have relied on them20. The oldest prophylactic with which we are acquainted, is suction. We have very ancient records of its employment, and, if we can believe these legends, a particular family enjoyed the privilege, or devoted themselves to this process of drawing, by the application of the mouth to the wound, the poison inserted by a venomous animal21. A ligature has also been recommended to stop the progress of the rabid poison, but, according with the present theories, it can have no preventive efficacy whatever. Cold-bathing, but particularly sea-bathing, as a preventive, is 20 Boerhaave complains of these impositions. "Nop jEschrionis apud Ga- lenum et Oribasium arcano de cancris combustis; nec Scribonii Largi famige- rata opiata ad rabiem Siculorum ; nec Peregrini consilio de pelle hysnae; nee JEiW, Rufi, Possidonii, cinere cancrprum cum theriaca; nec j aetata Palmario mcdela; vel nimis laudato Mayerno, Grew, et venatoribus stanoo cum Mithri- datio; nec in somniis sacris revelata radice cynorrhodonis; aliisve in coelum elato Iichene cinereo terrestri pimpinella, jecore rabiosi canes exusto, ct similibus exceptis." 2' Celsus strongly recommends this practice, and brings forward (he family of Psycllcs to prove how free it is from danger: "Non gustu, sed vulnere nocent." — "Ergo quisquis exemplum Psylli secutus, id vulnus exsuxerit, et ipse tutus erit, et tutuin hominem prsestabit." — De Medecin. lib. v, chap, ii, sect. 12. — Fothergill, Heister, and Vaughan, have spoken favourably of suction as a preventive. OR CANINE MADNESS. 237 a practice also of great antiquity, and, even yet, the uninformed classes place implicit reliance on it. Its incapability of insuring safety was, however, early noted; and Palmerius, Ambrose Parey, Desault, and others, were at much pains to discredit the practice : nevertheless, both hot and cold bathing long retained some powerful advocates1. However respectable the authorities in its favour, . the lamentable experience of many who have trusted to its efficacy, even when performed, as Van Swieten has it, ad sufficationem usque, but too well proves. Among the well-informed, therefore, no reliance is now placed on it. Mercury has long been employed as a prophylactic. Sau- vages must have been greatly deceived by its ill-deserved repu- tation2. Sir G. Cobb's famous Tonquin remedy, so highly ex- tolled by Claude Duchoisee, in India3, was prepared from the native and factitious cinnabars, with musk. Turpeth mineral, which is a sub-sulphate of this metal, was highly extolled by Tissot4, and has been very generally used among the dogs of this country. Many other authorities of note have extolled the preventive efficacy of mercury, from its power in counteracting the effects of the syphilitic poison5 ; but as it has entirely failed in man and beast, under every advantage of administration, so it has ceased to be relied on as solely sufficient to guard the constitu- ' " Protinus in balneum amittunt, eumque ibi desudare, duin vires corporis sinant, vulnere aperto quo magis ex eo quoque virus distillet." — Celsus de Med., lib. v, c. 47. Tulpius is warm in his commendation of sea-bathing: "Neque vidi hactenus quemquam (licet viderim plurimos) cui tempestive in mare pro- jecto quidquam sinistre postmodum evenerit, sed salutari hoc remedio vel llocci facto, vel tarde ac timide adhibito, dedere niulti irreparabiles supina? suae incuria; poanas." — Obs.

Neither has arsenic any more claim to the character of a preventive than it has as a curative. Dr. Mead's pulvis antilyssus, composed of lichen cinerens and black pepper, has wholly lost its reputation, although, during his practice, he expressed a wish that he knew as certain a pre- ventive for any other disease. The Ormskirk Remedy is also ano- ther striking proof how easily a reputation may be gained, and how undeservedly : for although palpable instances of its failure are numerous, it once enjoyed great reputation, and is even yet occasionally trusted to. The wafer plantain (alisma plantago) has also proved one of those unfortunate articles offered to notice, which only served to raise hopes it was doomed never to realize. As it came recommended by a Russian counsellor of state, M. Jalowsky, at the express direction of his government, it met with a cordial reception, and a full trial in England and else- where, but everywhere it proved fallacious, both as a preventive and cure. To enumerate all the other articles, particularly of the vege- table world, that at some period or other have been deemed pro- phylactics, would be endless. Among the most popular we may mention the eglantine, or wild rose ( rosa sylvestris, Linn.)?, pim- pernel (anagallis)*, deadly nightshade (atropa belladonna^, 6 Leroux, Oudot, Raymond, Lafond, Majault, Enaux, Chaussier, and Morveau, are neighbouring authors who have denied the efficacy of mercury in this case ; and, among ourselves, I believe all our best authorities, almost without exception, do the same. 7 The wild rose seems to have been a remedy of much repute in its day (Baudot, Mem. de la Soc. Roy., 1783). In a communication to the Royal Society of Medicine of Paris, M. Provost details the virtues of its inner bark. And, among the Sicilians, its spongy excrescences (bedeguar) are considered a powerful antidote to the rabid poison (Museo di piante rare du P. Boconi). According to Pliny, its virtues were revealed by an oracle; from whence we may learn, that a preventive efficacy was long ago attributed to it. 8 An account of its supposed anti-rabid virtues may be seen by consulting Hist, de la Med., Sprengel, torn, ii, p. 48; (Euv. de Bourgelat, Reflex, sur la Rage Voy. Journ. d'Agricult. p. 109. 9 As long as the time of Pliny, the belladonna has been used as a remedy against rabies. Apulei also notices it ; and in later times, Munch also, Hist, de la Soc. Roy. de Med., 1783, 2d part. At the present time, Mr. Youatt at- tributes some preventive efficacy to it.

The venomous stings of Hornets, Wasps, and Bees, may be relieved by applying the vegetable blue used to colour linen. Laudanum also, or vinegar or brandy, will, either of them, often remove the pain and inflammation speedily. CLASS IX. External and Local Inflammations. WOUNDS. Dogs are liable to become wounded in various ways, and their wounds, however bad, are not, generally, much attended to, from an opinion that the animal's tongue is the best dressing. This is very questionable : in some instances, I am certain, no application can be worse to a wounded dog than his own tongue. Whenever dogs are at all inclined to foulness, as a tendency to cuticular complaints is called, a sore, so licked, is sure to be- come mangy, and to be aggravated by the licking. Wounds into the chest or belly should be closed up as soon as possible, to prevent the external air from penetrating : a stitch or two made in the integuments is proper ; over which, some adhe- sive plaister, and a bandage over that, may be applied. If the intestines protrude in a wounded belly, and the bowels are them- selves wounded ; first, neatly stitch up the intestinal opening, and return the gut: then close the wound in the integuments, leaving the thread which united the gut, if long enough, hang- ing without the external wound. In wounds of arteries or veins, the haemorrhage should be stopped by pressure : should that not succeed, take up the vessel with needle and thread. Wounds into joints occur from cuts, and often from stabs : great inflammation is apt to follow, and the dog is often lamed for life. If the synovia escapes by a very minute puncture, and the inflammation is not yet very extensive, treat exactly as in horse practice, by firing with the budding iron. WOUNDS. 257 If the wound be a lacerated one, and not already much inflamed, place over it a pledget of lint, and over that a thick paste of lin- seed meal ; after which, baudage the whole up moderately tight. Should the inflammation be great, reduce that by a common poultice, and then endeavour to close the joint as above. Jn all extensive and lacerated wounds, a stitch or two should be made with a larg^e needle and thread, as it will reduce both the sore and the scar ; but, as such stitches soon ulcerate out in the dog, so the edges should be still further secured by slips of sticking-plaister. A recent wound should be cleansed from the dirt, and then covered up : when it begins to suppurate, dress with any mild ointment. In thorn wounds, or others made with splinters, carefully examine that nothing is left within them; otherwise no attempts to produce healing will prove successful. The most common wounds in dogs arise from the bites of others ; and under any such circumstance, should any suspicion arise that the dog was mad by which the wounded one was bitten, pro- ceed as directed under Rabies. The wounds arising from com- mon bites, in general soon heal of themselves : if, however, they are very extensive, wash them with friars' balsam, to prevent their becoming gangrenous. Fistulous wounds, in glandular parts, often prove very obsti- nate. In such cases, means must be taken to get at the bottom of the sinus, and to raise a more healthy inflammation therein ; which may be done, either by injecting something stimulant into it, as a vitriolic wash, or by passing a seton through it. Some fistulous wounds, such as those in the feet and about the joints, will often not heal ; because either the bones, or the capsular ligaments, are diseased : in such, the wound requires to be laid open to the bottom, and to be stimulated with oil of turpentine, or with tincture of Spanish fles, daily, till the diseased bone or ligament is thrown off, when a healing process will immediately commence. 258 ULCEROUS AFFECTIONS. Dogs are subject to ulceration of various parts of the body, and such state is dependent on very different causes. Cancer, which is the worst ulcer we are acquainted with, is but little common in the dog : those cases, however, in canine pathology, that do approach its character, are noticed under the head Cancer. Avery malignant ulcer sometimes breaks out in the lips, face or neck, in distemper, and is there noticed. In virulent canker, the internal, and sometimes the external ear also, becomes at- tacked with extensive ulceration ; I have even seen it proceed so far, as to destroy the dog. The eyes become frequently ulcerated in distemper; but cure the distemper, and the eyes reinstate themselves, although the ulcerative process was very considerable. The Blain is an ulcerous affection of the sides and under sur- face of the tongue, which sometimes extends into the cheeks : it is often attributed by country people to being poisoned with eating some herb, or by killing a toad or serpent, and by other equally sapient causes. It is sometimes attended with constitu- tional disturbance ; at others it interferes but little with it. In the former case, give antimonial powder in doses of two or three grains, twice a day ; when there is no constitutional dis- turbance, attend then principally to the blain or vesicles which will be seen as large livid bladders, studding the sides and under surface of the tongue. Lay these open, and wash with a solution of zinc or alum several times a-day. Glandular parts in dogs are very liable to ulceration; the most common among which are the teats in bitches.— See Scirrhus.— The vagina, sheath, or bearing, and sometimes the womb also, are found to be affected with a morbid ulcerous state, which is very usually accompanied with a fungous excrescence, from which blood exudes, or a bloody ichor. This disease partici- pates more of the nature of cancer than any other to which dogs are generally liable. — See Cancer. The penis is likewise the subject of an ulcerous affection, TUMOURS. 259 which is also commonly accompanied with a spongy fungous ex- crescence, exuding a bloody ichor: hut it does not erode the neighbouring parts, and appears to partake more of the nature of a vascular warty substance, than that of cancer. This state of fungous excrescence on the penis is often mistaken for a disease of the kidneys or bladder. A few drops of bloody fluid appear now and then to come from the dog ; and, as in the act of making water, the last effort squeezes the fungus, and forces a drop or two at that time, so it is concluded, that either the urethra, or the kidneys, or bladder, is affected. But, if the dog be held, and the prepuce stripped down, so as to expose the penis through- out, there will generally be found one or more large fungous knobs, from which this bloody secretion proceeds. The cure consists in removing every one of these excrescences, carefully and completely, with the knife, leaving no part of the base or pedicle of each : having so done, sprinkle the excised part with a little alum in fine powder ; and, unless the excres- cence has been very considerable (when it will be necessary to remove the prepuce every day to prevent an union of it to the penis), the rest may be left to nature. In very slight cases, where these fungi have appeared as warts only, which is not un- common, I have removed them by merely sprinkling them daily with powdered savine three parts, crude sal ammoniac two parts. Other ulcerous affections are noticed under the head Wounds. TUMOURS. Dogs are subject to a variety of swellings or tumours. If we commence our account with the head, we shall find that it is the subject of a peculiar tumefaction, not very unlike human erysi- pelas. In dogs of a gross, full habit, from natural plethora, or from over-feeding, the head will sometimes become suddenly enlarged, hot, tender, and painful, accompanied with thirst, quickened pulse, and every mark of fever. In a day or two a general eruption takes place, which proves to be a kind of acute R 2m POLYPUS. mange. — See Mange. In distemper also, a phlegmonous tu- mour occasionally forms upon some part of the face, generally about the lower jaw, which soon maturates, but afterwards forms an unhealthy and spreading ulcer. — See Distemper. The flap of the ear is also subject to a very considerable tumour, containing serum.— See Tumefied Flap of the Ear. The neck is likewise subject to tumefactions. The principal of these cases arises from an enlargement of the glands on each side of the windpipe, and is called Bronchocele ; which see. The neck will sometimes also become swollen from rheumatism. — See Rheumatism. On the body, glandular tumours, or wens, will likewise form in various parts : there is hardly any situation in which I have not seen them, and extracted them from. — See Cancer and Glandular Swellings. But the most frequent glandular tumours, are those that form in the teats of bitches.— See Scirrhus. In old bitches, particularly in spayed ones, there often appears a tumour, or en- largement, on each side of the back about the loins ; which, though it elevates the skin externally, yet is evidently more deeply situated. These swellings arise from large accumulations of fat about the ovaria. POLYPUS. Now and then an excrescence is found protruding itself from some cavity, of an indeterminate form, but usually pendulous and nipple-shaped. 1 have seen them in the nose, within the uterus and the sheath of the penis, as well as pendant from other parts also; but by much the most usual situation in which polypi are found, is within the sheath or vagina of the bitch. When the pedicle of the polypus can be reached to its origin, it may be taken off by excision : when this cannot be conveniently done, still a ligature may commonly be introduced around its base, and suf- fered to remain till the whole drops off. I have frequently re- moved polypi by both these methods, without future inconveni- ence or reproduction. 2G1 TUMEFIED OR SORE FEET. When the feet of dogs become sore by travelling, it is common to wash them with brine ; but this is not altogether a good prac- tice. It is better to bathe them with greasy pot-liquor, milk, or buttermilk, and afterwards to defend them from stones and dirt, by wrapping them up. When the feet become sore from any dis- eased affection of the claivs, the proper treatment may be seen under Mange, and under Cutting of Claws, in Class XII. Occasionally, however, violent inflammation follows very hard and continued travel, and the spongy balls of the feet take on a slow suppuration ; the dog can hardly be moved, and his time is spent in licking them : often he has strong symptoms of fever. A poultice of linseed meal ought to envelop each foot, which should be renewed once a-day ; if the dog gnaws it off, ap- ply fomentations twice a-day; for it is essentially necessary that a healthy suppuration should be established as quick as pos- sible, otherwise a species of founder takes place, and the do°- •11 • will remain tender footed ever after. As soon as matter fluc- tuates, open with a lancet. The claws by undue growth often curve, and indent their points within the integuments, and occa- sion tumefaction of a toe : this must be remedied by cutting, away the indenting portion.— See Cutting of Claws in Opera- tions. A tumefied toe or toes we occasionally meet with, where around the base of the claw the secretory part or quick is swol- len, inflamed, and excoriated. This is a mangy affection, and is described with the anomalies of Mange. HERNIAL TUMOURS. As the dog may be the subject of most of the varieties of hernia, so these tumours may be various; but that to which he is naturally most prone, is epiplocele, and which tumour is by no means uncommon in such as are very fat : the unclosed state of the abdominal ring, and the very great dimensions of the omen- tum, particularly when enlarged by an extraordinary quantity of r 2 262 OPHTHALMIA. adipose matter, and pressed on by other accumulations, as may be supposed, very naturally incline it to be gradually pressed through the ring, and to occupy the scrotal bag, where I have seen the distention enormous. I never saw a case of strangula- tion ; but, if such were to occur, without doubt it would shew itself by the distention and colicky pains. The operation of the taxis must be first attempted ; and should that fail, proceed to dilate the stricture by which it is strangulated. CLASS X. Diseases of the Eyes. OPHTHALMIA, OR INFLAMMATION OF THE COATS OF THE EYE. Idiopathic Ophthalmia.- Dogs are occasionally attacked with inflammation of the coats of the eye or eyes ; in which case, there is an impatience of strong light, the conjunctiva is red, and when the affection is intense, the pupil itself is clouded with milky whiteness, or otherwise, the bloodvessels of the opaque cornea are seen in red lines extending over it. If this state of the pupil is not present at the first, the continuation of the affection for se- veral days commonly produces it: now and then, the humours of the eye are seen to exhibit a reddish tinge ; but this is not fre- quent. The causes of the affection are various : excitements of any kind, as violent exertions, heat and cold alternating in ex- treme degrees occasion it : thus I have seen it follow from plung- ing into water when the dog has been very hot, and not accus- tomed to the change. Ophthalmia is also occasioned by external violence, and by irritating matters settling within the eye ; or stings, &c. without. These cases are known usually by one only being affected ; but I have seen pointers, setters, and spaniels suddenly thus seized after hunting in cover, from some poisonous herb ; in which case it is seen in both eyes. Thorn wounds, scratches from cats, OPHTHALMIA. 203 &c, are productive of it ; but it is commonly confined to one eye. The treatment is not dissimilar in principle in all these cases : should the inflammation be very considerable, bleed, purge, and keep low: foment the eyes with an infusion of poppy heads, until the light does not distress the dog, when apply the following wash several times a-day : — Superacetate of lead (sugar of lead) half a drachm Rose water 6 ounces. When the inflammation is somewhat lessened, use the fol- lowing : — Sulphate of zinc 1 scruple A weak infusion of elm bark 6 ounces Brandy 1 tea-spoonful. Sometimes the following has moderated the irritation when other applications have failed: — Tincture of opium half a drachm Infusion of green tea 4 ounces. All exposure to strong light, or other sources of irritation, as foul housing, &c, should be avoided. In very bad cases, I have sometimes scarified the insides of the eyelids, and even the white part of the eye itself, by means of the point of a fine lancet, with very great benefit ; and in others, where much obstinacy in the complaint has shewn itself, particularly in foul-coated dogs, a seton in the neck has done much good. After the active symptoms have disappeared, should any opacity of the cornea remain, a small pinch of a powder may be sprinkled into the eye once or twice a-day, composed of one scruple of acetate of lead, and one drachm of calomel. Ophthalmia of Distemper. — This might be called a specific ophthalmia, from peculiarities attending it : or it might be named symptomatic, as being an accompaniment of a particular disease. That it is very different from idiopathic ophthalmia is proved by its consequences ; for while the remaining effects of the idiopathic attack are in the ratio of the intensity of the inflammation, in ihe 264 CATARACT. symptomatic they bear no proportion whatever to it. The dis- temper, as an inflammatory affection of the mucous membranes, might be supposed, a priori, likely to extend its affection to the eyes also ; which it does in a marked degree, and with almost invariable certainty ; so that distemper is frequently characterized as a defluxion from the eyes and nose. The early symptoms of this ophthalmia are not unlike those which betoken the idiopa- thic attack ; except that a more early and more abundant appear- ance of a purulent secretion is common. The injection of the opaque, and the cloudiness of the transparent cornea, are, in the cases I point at, intense ; to which very frequently succeeds, in the very centre of the pupil, a minute circular speck of ulceration that sometimes remains stationary during the distemper. At others, it extends both in depth and breadth ; sometimes so much as to evacuate the aqueous humour : when this occurs, there usually follows a luxuriant sprouting of fungoid granulations, which give great pain, and at last, to all appearance, totally dis- organize the eye. It is now that the peculiarity of this ophthal- mia shews itself ; for from this apparent ruin of the structure of the eye it will gradually reinstate itself, and very often there will not remain a trace of injury behind. The disease is most frequently confined to one eye only ; bnt I have seen it in both. The topical treatment of the ophthalmia of distemper is blended with that of the idiopathic ; but the constitutional is referrible to the treatment of distemper itself; for to cure that, is to remove the ophthalmia. CATARACT, OR OPACITY OF THE CHRYSTALLINE LENS. The chrystalline lens occasionally loses its ■pellucid appearance in dogs, as in ourselves, and from the same causes : a common one is idiopathic ophthalmia ; that accompanying distemper but sel- dom occasions it. In old dogs cataracts are by no means un- common, from a breaking up of the strength of the parts; nor are they very unusual either in younger dogs, being sometimes the DROPSY OF THE EYEBALL. 205 result of external injury, and at others it steals on as a chronic affection of the organ : but there is this difference between the disease in the old and the young-, that, in the former, both the eyes commonly become affected; whereas, in the latter, it is usually confined to one only. In all these cases the before-de- scribed powder may be blown into the eye; but it is very seldom that any treatment arrests the final termination in blindness. AMAUROSIS, OR PARALYSIS OF THE OPTIC NERVOUS EXPANSION. This is not a very common affection, but it is now and then seen to follow epileptic fits ; and I have known it come on without apparent cause also ; and I witnessed it once consequent to a fall into a gravel-pit. It is not difficult to see the rationale of the disease in these cases : nor are we led thereby to be very san- guine in our hopes of cure. Local and constitutional tonics may be applied, with stimulant applications to the back of the head. DROPSY OF THE EYEBALL. An accumulation of the liquid contents of the eyeball now and then also occurs, which greatly distends the globe of the eye, and by its pressure occasions an imperfect contraction of the iris. I once punctured the sclerotic coat, and evacuated the fluid ; but great inflammation followed, and the organ gradually wasted away. 1 have also introduced both stimulants and absorbents, but particularly calomel. I have tried electricity, pressure, setons, and blisters ; and all without effect, except in one instance, where a seton in the cheek, with calomel introduced between the lids, appeared to gradually lessen the distortion of the globe : but the owner grew tired of the trouble and chance of expense, and destroyed the dog before the precise effect could be ascertained. I have also seen accumulation, within the globe of the eye, of blood, or extravasated and serous effusion adding to it. In one such case I evacuated the engorgement by a couching needle, 2<>(J MANGE. and the eye was saved. This might be called traumatic dropsy t as being effected by a thorn stab. EYELIDS, ULCERATED. There is now and then a mangy affection met with which is confined to the eyelids, attended with enlargement, ulceration, and a loss of hair. I have seen it produce innumerable little orifices, each of which threw out a muco-purulent fluid. In one instance an extremely minute syringe had a fine canula adapted to these secreting orifices ; by which a mild solution of nitrate of silver was introduced every day. By these means, and appa- rently by these only, could this disease be got under. In tlie generality of cases which occur, the following will be found effective : — Ointment of nitrated quicksilver 1 drachm Supei acetate of lead {sugar of lead) 20 grains Spermaceti ointment 3 drachms. Anoint the parts, night and morning, lightly with it, watching the dog afterwards that he does not rub it into his eyes. Inter- nal medicines will also assist the cure. — See Mange. CLASS XI. Diseases of the Skin. MANGE. This cutaneous affection is very common among dogs of every variety, and is observed in his congeners, the fox and wolf also : it is not altogether unusal to find a dead fox so mangy, as ap- parently to have been destroyed by its virulence. It has been compared to itch in the human, and not without justice ; as, if I am not greatly mistaken, the canine mange is capable of produ- cing the human itch : but, whether the human itch can be given to dogs, is a point which my experience docs not enable me to MANGE. 267 determine. The canine mange is a chronic inflammation of the skin, dependent, in some instances, on a morbid constitutional action : it is infectious also, from maisms produced from animal exhalations ; and it is notoriously contagious from personal com- munication with one affected. It is not, however, so completely contagious, in all its varieties, as is supposed, for I have known dogs to sleep with affected ones for some time without becoming mangy ; but in the majority of cases it is otherwise ; and in some the predisposition to it is such, that almost simple and momen- tary contact will produce it. The mange which is received by con- tagion is more readily given to another than that which is gene- rated. The uniform presence of animalculi within the psoric pustules has revived the idea that it originates in the attack of acari. Mange is also hereditary. — A bitch, lined by a mangy dog, is very liable to produce mangy puppies ; but the progeny of a mangy bitch is certain to become affected sooner or later ; and I have seen puppies covered with it when a few clays old. The mor- bid action by which mange is generated is excited in various ways, and by various causes. When a number of dogs are con- it fined together, the acrid effluvia of their transpiration and urine begets a miasm productive of a virulent mange, very difficult to be removed. Close confinement, with salted food, is even more certainly productive of mange : thus dogs who have come from distant countries, on ship-board, are generally affected with it. Very high living, with little exercise, is a frequent cause : a state nearly approaching to starvation is also not unfavourable to it. In both these apparent contrarieties, the balance between the skin and the digestive functions is not preserved, and the disease fol- lows as a necessary consequence. The disease has some perma- nent and fixed varieties ; it has also some anomalies ; but the pru- ritus or itching is common to all. TJie scabby mange, one of the most common forms under which this eruptive complaint appears, is an extension of the secretory pores of the skin in very minute red vesicles, that at first are dis- 268 MANGE. tinct, but as they extend become pustular, confluent, and scabby. Sometimes simple linear cracks of the cuticle seem to pour out a serous fluid, which concretes into scab. It is occasionally confined to the back; at others it is found principally in the joints of the extremities. The red mange, so called from a redness of both skin and hair in the parts affected, is likewise not unfrequent, and partakes much of an herpetic character. In this variety there is less pustular eruption, but nearly the whole skin of the body, particularly in white-haired dogs, is in a state of active inflammation : it is also hot to the feel, and itches intolerably. In the red mange, the hair itself becomes morbidly affected, and alters in its colour, particu- larly about the extremities : it also falls off, and leaves the skin bare, much thickened, and puckered into stubborn wrinkles. Dogs with the strong coarse hair called wired are very liable to this state ; in which a magnifying glass applied will often detect innumerable minute ulcerations, covered by furfuraceous scales. A direct ulceration of the sebaceous glands is another form of mange, but is much less frequent than either of the former : these glands in this state appear to become internally ulcerated, and have their sebaceous outlet preternaturally enlarged. The affec- tion seldom shews itself universally, but partially, as over the face, around the joints, and in solitary patches over the rest of the body. The diseased parts are tumid, shining, and look spongy ; from the little openings of which a moisture, between mucus and pus, issues. I have not observed this affection but in the larger breeds of dogs ; and usually, I think, in pointers and setters. I have seen it almost entirely confined to the eyelids, as noticed in Diseases of the Eyes. A cuticidar eruption, called surfeit, is a fourth appearance that mange frequently assumes. It seems, in many cases, the con sequence of some active inflammatory state of the constitution, frequently of some great local internal inflammation ; in which cases it puts on something of an acute form. It sometimes breaks out suddenly in bitches after pupping; and in dogs newly re- MANGE. 209 covered from distemper; in fact, any great vascular excitement may produce it : thus, when a dog travels during a great part of a very hot day, and becomes afterwards exposed to cold, a surfeit is oftentimes the consequence. It is usually seen in the form of partial blotches, it being seldom that it extends universally over the body. In some cases there is little appearance of elevated scab ; but large patches shew themselves, from which the hair has fallen, and left the skin bare and rough from the branny scaly eruption, which itches with more or less violence. Some sports- men allege that a surfeit is sometimes occasioned by giving food in a hot state. Salt provisions have certainly brought it on ; and long-continued feeding on oat or barley meal has doue the same. Acute mange. — Besides that variety just noticed, there is yet a more directly acute form of the complaint, which puts on an ap- pearance not unlike erysipelas in some instances ; in others it is a pure erythema, or red efflorescence ; but more frequently it is accompanied with some ulceration. It commences by a direct fe- brile attack, with panting, heat, and restlessness ; next some part of the body (usually the head) begins to swell, which, the second or third day, gives place to ulceration of the nose, eyelids, lips, ears, neck, &cc. This ulceration proves superficial, but extensive ; and continues a longer or a shorter period, as the treatment is more or less judicious. Bleeding, aperients, and febrifuges, form the constitutional remedies : the topical ones are tepid fomenta- tions the first two days ; and, when the tumefaction has given place to ulceration, the application of a cooling unguent of su- peracetate of lead {sugar of lead), with spermaceti ointment, will be proper. What remains of the affection, in a week or ten days' time, may be treated as common mange. The anomalies of mange are numerous; among them may be reckoned the acute variety just noticed, but which was appended to surfeit, from some similarity it possessed to that form of the complaint. Local mange, as an anomaly, exists under as many forms as the parts it attacks. Almost every eruptive complaint 270 MANGE may degenerate into mange, such is the predisposition in all the - carnivora to psoric and herpetic affections. Those that deserve specification are canker both within and without the ear, which will follow in due order. Inflamed scrotum is of the mange variety, and partakes of the nature of erysipelas, which see. — Ulcerated Eyelids, already de- scribed with Diseases of the Eye, are of the like kind. Diseased toes or claws. — The affection here meant is a singular anomaly of mange of the following kind. One of them will appear highly inflamed, swollen, and somewhat ulcerated, around the claw. In such a case the dog employs himself in continually licking it, which, instead of doing good, as is supposed, always makes it worse. It is commonly mistaken for some accidental injury ; and the owner is surprised to find, that neither the dog's licking, nor his own attempts to make the toe sound, succeed. The fact is, that this is simply a mangy affection, and may be readily cured by applying the sixth ointment directed for the cure of mange. If it should, however, prove very obstinate, the first ointment directed for Canker on the Outside of the Ear may be then tried with confidence. In either case, the foot must be sewed up in leather, to prevent the dog getting at it, taking particular care not to bind it up too tight : but the securing of the diseased part from being licked is essential to the cure. Mange is apt to be considered more troublesome than hurtful, which is a great error ; for it is not only invariably hurtful, but very often fatal also : when long continued, it frequently ends in dropsy. It sometimes diseases the mesenteric glands, and the subjects of it die tabid : neither in any case can it be neglected with impunity. In sporting dogs it is injurious to their qualities as well as their health: their scent inrariably becomes im- paired, and their general powers are always weakened by its irritation . Treatment of mange. — Whatever similarity may exist be- tween this complaint and the human itch in other respects, a very great difference is observed between the obstinacy of the one, and MANGE. 271 the ease with which the othermay be cured. Medical practitioners among- the human consider the itcli as local ; but veterinarians, to their vexation, will find mange constitutional ; too often very deeply rooted also iu the dog. Like the human itch, it is, how- ever, most judiciously treated by remedies that excite absorption ; and sulphur, the grand panacea of the one, is also the general application for the other : but, as mange exhibits greater va- rieties, and is altogether more difficult of cure, it is seldom that we can trust to this alone for that end. The following formulae are adapted for the first described form of mange : — No. 1. — Powdered sulphur, yellow or black 4 ounces Muriate of ammonia (sal ammoniac, crude) powdered half an ounce Aloes, powdered 1 drachm Venice turpentine half an ounce Lard, or other fatty matter 6 ounces. — Mix. Or, No. 2. — Tobacco in powder half an ounce White hellebore in powder half an ounce Sulphur in powder 4ounces Aloes in powder 2 drachms Lard, or other fatty matter 6 ounces. Or, No. 3. — Powdered charcoal 2 ounces Sulphur powdered 4 ounces Potash 1 drachm Lard, &c 6 ounces Venice turpentine half an ounce. Or, No. 4. — Sulphuric acid (oil of vitriol) 1 drachm Lard 6 ounces Tar 2 ounces Powdered lime 1 ounce. Or, No. 5. — Decoction of tobacco 3 ounces Decoction of white hellebore 3 ounces Oxymuriate of quicksilver (corrosive sublimate) 5 grains. Dissolve the corrosive sublimate in the decoctions, which should be of a moderate strength ; when dissolved, add two drachms of powdered aloes, to render the mixture nauseous, and prevent its I 272 MANGE. being licked off, which ought to be very carefully guarded against : the best means for this purpose is a muzzle having a very fine wire capping or mouth-piece, which will effectually prevent the dog from getting his tongue applied to the ointment, which would prove his almost certain destruction. When, therefore, the ap- pfication contains mercury, tobacco, or hellebore, it is best not to depend on the bitter of the aloes as a preventive to licking, but to apply an effective muzzle, or otherwise to sew the dog up alto- gether in a dress, watching him, however, that he does not gnaw it off. The formulae for red mange are as follow : — No. 6.— Of either of the ointments already pre- scribed, 1, 2, or 3 6 ounces Mercurial ointment, mild 1 ounce. — Mix. Or, No. 7.' — Powdered charcoal 1 ounce Prepared chalk 1 ounce Superacetate, or sugar of lead 1 drachm White precipitate of quicksilver 2 drachms Sulphur 2 ounces Lard 5 ounces. In some cases, the mange ointment, No. 4, alternated with No. 6, one being used one day, and the other the next, will be found beneficial. In others, benefit has been derived from the wash, No. 5, united with Hme water. In slight cases of red mange, the following has been found singularly successful : — No. 8. — Oxymuriatc of quicksilver (corrosive sublimate) powdered 6 grains Sulphuretted potash (liver of sulphur) ... half an ounce Lime water 6 ounces.— Mix. The third variety requires a considerable difference in the treatment. When the little spongy openings, piercing the cel- lular tissue, will admit of it, they should be injected, by means of a very minute syringe, with the wash No. 8. The general surface should also be anointed with the following : — No. 9.— Ointment of nitrated quicksilver 2 drachms Superacetate of lead 1 scruple Washed flowers of sulphur half an ounce Lard 1 ounce.— Mix. MANGE. 273 The fourth kind of mange, called surfeit, requires little variety in the treatment, except that bleeding-, purging, with every other part of a depleting treatment, are here more particularly necessary. With regard to the external applications, it should be remembered both in this, and all the otber kinds of the disease, that, when the sores are very irritable, and much inflamed, it will be frequently essentially necessary to allay the heat and inflammatory irritation in them before they will bear any of the regular mange applications. The best means of doing tins will be by anointing them with the following for a few days : — Superacetate, called sugar of lead 1 drachm Spermaceti ointment 2 ounces. When the irritation is allayed, proceed with the ointment No. 3, or alternate this with No. 6. Besides the fixed varieties before described, mange puts on dif- ferent appearances in different subjects ; but they may be all re- ferred to one or otber of these heads. Numerous domestic reme- dies are in use, but, I believe, no one article acts so favourably as several united ; and it may, perhaps, not be too much to say, that the recipes already given will meet every variety : their effi- cacy has been proved by long experience and a successful prac- tice. Tobacco water is often used for the cure of this complaint, and, in very slight cases, it frequently does some good ; but, un- less used with extreme caution, it is a most dangerous remedy, from the tendency all dogs have to lick themselves ; and, when they do this with tobacco, the effects are often fatal, as I have several times seen. Great caution is also requisite, for the same reasons, with all kinds of washes in which there is any thing active, as mercurials, &c. It is not an uncommon practice to dip mangy dogs in the tanners' pits ; but it is a very filthy and not often an efficacious one, except in very slight cases : in such in- stances, an infusion of oak bark, with a little alum, would of course do as well. Having detailed the outward applications, it becomes neces- sary to mention the internal remedies that are required. When 274 MANGE. mange is generated, the constitution must be at fault to produce it ; and, when it is taken, it will itself affect the constitution : so that in all, except very slight cases indeed, some internal remedies are requisite. In very full habits, and particularly in red mange, bleeding is very proper18. I have also, in some in- stances, experienced benefit from a seton placed in the neck as a counter drain, particularly when the head has been much affected. It is also very requisite to attend particularly to the food : what- ever has been injudicious, both as to quantity and quality, should be altered. Frequently a total change in the manner and matter of feeding assist the cure very materially. — See the subject of Feeding. Purges, when regularly administered, often prove very useful ; for which purpose Epsom salts may be given, two or three times a-week, in mild doses. But the most effectual inter- nal remedy is a judicious use of alteratives. Red mange requires the aid of mercurial alteratives. Indeed, they assist in every variety of it, but this one can hardly be cured without. The following formula is a good one : — Black sulphurct of quicksilver (JElhiops mineral)... 1 ounce Supertartrate of potash (cream of tartar) 1 ounce Nitrated potash (nitre) 2 drachms. Divide into sixteen, twenty, or twenty-four doses, according to the size of the dog, and give one every morning or evening. Any of the other medicines of this class, mentioned under the head Alteratives, may be also used on these occasions. In desperate cases the following may be tried, after the others have proved unequal to the cure : — Sulphuric acid (oil of vitriol) 10 drops Conserve of roses ) (>unce Flour of sulphur half an ounce. Divide into eight, twelve, or fifteen balls, according to the size of the dog, and give one every day. ,„ In the Philosophical Transactions, No. xxv, p. 451, is detailed a case f a mangy dog successfully treated bj transfusing into him the blood from a heaZ dog.

Dissolve, and make twelve or fifteen doses of it, according- to the size and strength of the body, and give one every night and mornino-. With regard to the manner and frequency of external applica- tions, they should, particularly when liquid, be used every day- The mercurial ones require caution, not only as already insisted on, to prevent the dog from licking them, but also to watch that salivation may not be occasioned by their use. When mercurial preparations are licked by dogs, they are apt to occasion violent and dangerous diahrroea. Not only, therefore, should the lickino- 1 w t> be very carefully guarded against; but, when any danger of this kind has occurred, a dose of castor oil should be immediately given ; after which, astringents, with a small proportion of washed sulphur in them, will prove useful.— In the use of the unguents, it is necessary to remark, that they are too apt to be smeared over the hair, without being applied at all to the skin itself. It requires, at least, two hours to dress a dog thoroughly. The hair should be parted almost hair by hair, and a small quan- tity of ointment should be rubbed actually on the skin, between the parted hairs, by means of the end of the finger. After every part is done, the hair may be smoothed down, and the dog will appear, when the operation has been neatly managed, nearly as clean as though nothing had been applied. After three or four dressings in this way he may be washed with soft soap and water, and the ointment may be again rubbed in, and again washed off every fourth day, until the cure is complete. In old and bad cases of mange, it will be frequently requisite to continue the treat- ment a very considerable time, to ensure a perfect removal of 'the complaint. I once occasioned a very favourite setter, who had had virulent mange five years, to be dressed every day, or every other day, for ^extraordinary period of twelve months, before 276 CANKER IN THE EAR. I could completely conquer the disease : but this determined per- - severance effected a permanent cure. CANKER IN THE EAR. From confinement and luxurious living, dogs become subjected to various complaints, that evidently arise from the formation of too great a quantity of blood, and other juices; which, not being spent in support of the body, find themselves other outlets. Canker in the ear is evidently produced by this disposition in the constitution to throw off the superfluity accumulated within. In these cases, the dog is first observed to scratch his ear frequently ; on looking within which a red granular appearance is seen, from dried extravasated blood. If the complaint is not stopped in this state, it proceeds to ulceration, when the internal part of the ear, instead of being filled with dry blood as before, will be found al- ways moist with purulent matter. The dog now continually shakes his head from the intolerable itching ; and, if the root of the ear is pressed, the pus within crackles, and much tender- ness is expressed. When canker has remained long, the audi- tory canal becomes closed, and the hearing lost : now and then the ulceration penetrates deeply inwards, and destroys the dog. I have also known instances where the ulceration has assumed a cancerous appearance, and extended itself over the face. This complaint appears to have also another source besides over-feeding, heat, and confinement ; which is, the action of wa- ter within the ears; for it may be observed, that all dogs who fre- quent the water much are more disposed to canker than others. Any kind of dog may contract it thus, particularly when aided by artificial habits, as heat, confinement, and high living; but Newfoundland dogs, poodles, and water spaniels, are liable to it when not so artificially treated. Perhaps the length of hair around their ears, not only keeps these parts hot, but also re- tains the water within, and thus encourages an afflux of fluids or humours, as they are termed, to them. That the water has this I CANKER IN THE EAR. 277 tendency is certain, for I have frequently seen it removed by merely keeping- such dogs from the water ; that is, in those cases where the feeding and exercise were proportionate, and the fatness has not been inordinate. The cure, it is rational to conclude, must be either simple or more complicated, according to the cause producing the disease. When- ever there is much fulness of habit, and the dog is very fat, or when he has been subjected to much confinement in a hot close situa- tion,, these circumstances must be immediately rectified. Absti- nence and purgatives will reduce the fat ; a cooler situation must be chosen, open and unrestrained ; full exercise must be allowed, to assist also in giving another direction to the fluids. In those cases where there are symptoms of a constitutional foulness, which shew themselves by a red itching skin, stinking coat, and mangy eruptions ; in such, in addition to exercise, a vegetable diet, cleansing alteratives, and occasional purges, should be given. — See Alteratives. In very bad cases a seton may be properly in- troduced in the neck, and suffered to remain there, until the benefit derived from it is very apparent. When the cankered dog- is very fat, occasional bleeding is also beneficial. External applications are likewise essential to the cure, and in some mild cases are all that are necessary, particularly where it may be supposed that swimming much, or too frequent washing, may have principally tended to produce the complaint. In the early stages, a wash composed of half a drachm of superacetate (sugar) of lead, dissolved in four ounces of rose or rain water, is often all that is necessary. A small tea-spoonful may be introduced (previously warmed to a blood heat, to prevent surprise) night and morning, rubbing the root of the ear at the same time, to promote the entrance of the wash into the cavities. In more obstinate cases, it is prudent to add fifteen or twenty grains of vitriolated zinc (white vitriol) to the wash ; and if, instead of water, a decoction of oak bark is made use of to form the wash, it will greatly promote the end desired. In some cases, acetate of copper (verdigris), mixed with oil, has proved beneficial when s 2 278 CANKER ON THE OUTSIDE OF THE EAR. introduced in the same manner. In others, submuriate of quick- silver (calomel) and oil have produced amendment in the same way. A very weak injection of the oxymuriate of quicksilver (cor- rosive sublimate) has succeeded when every other application lias failed. A very mild injection of nitrate of silver, as one grain to two ounces of water, has done much good also. CANKER ON THE OUTSIDE OF THE EAR. Although this complaint bears the same name with the former, in appearance it is very different. It consists of an ill-disposed ulcer, which is usually situated on the lower edge of the flap or pendulous part of one or both ears, dividing it into a kind of slit. It seems to itch intolerably, and is therefore kept in a continual state of aggravation by the shaking of the dog's head. It is not a little remarkable, that whereas long-haired dogs (as Newfound- lands, setters, and water-spaniels) are more subject to internal canker of the ear ; so smooth-coated dogs (as pointers and hounds) are the only ones, in general, affected with this outer canker. Pointers and hounds who have been rounded, by having the flap shortened, are less liable to it than those who have their ears of the natural length. From this circumstance it is common to round them after the disease has appeared ; but it frequently fails to cure, unless the part taken off extends considerably beyond the surface of the ulcerated slit. It is common also to burn out the ulcer either with the actual cautery, or with some caustic sub- stance ; but this also proves an uncertain remedy. In full habits, and where over-feeding and confinement may be supposed to have had any share in the production of the disease, the same rules must be attended to, with regard to the constitu- tion generally, as are detailed for the internal canker. But in other cases an external application is usually found sufficient. An unguent, made with equal parts of ointment of nitrated quick- silver and calamine cerate, maybe applied once a-day, carefully securing the ear from the injury occasioned by the shaking ol TUMEFIED FLAP OF THE EAR. 279 the head, by a sort of head dress, during its use. Or the follow- ing may be tried : — Oxymuriate of quicksilver (corrosive sublimate) very finely powdered 3 grains Cerate of calamine (Turner's cerate) 1 drachm Sublimated sulphur (milk of) 1 scruple. In some cases, the oxymuriate of quicksilver has become more efficacious in a wash, six grains being dissolved in four ounces of water. Strong astringent lotions are sometimes useful, as alum dissolved in a decoction of oak bark. When the disease proves very obstinate, excision must be resorted to, taking care that the whole, not only of the immediate cracked part, but also of its tumefied edges, are included in the operation. TUMEFIED FLAP OF THE EAR. From a similar repletion of habit, and from the same attempts in the constitution to find an outlet to the superfluous humours, or fluids, the flap, or pendulous part of the ear, becomes not unfrequently the subject of another complaint, which shews itself by a tumour, whose prominent part is always on the inner side. It sometimes swells to an enormous size, and occupies the whole of the inner surface of the flap, which then presents a shining tumid mass, so painfully tender and weighty as to prove very distressing to the animal. It is most frequently met with in those dogs whose external ears are long, as setters, pointers, hounds, poodles, and spaniels. Attempts at dispersing these tumours always fail ; for the collections are, from the first, less phlegmonous than serous ; the only mode of relief is therefore to evacuate the contents : but it is too common merely to make a small opening for this purpose, which is almost certain to heal immediately, and a fresh accumulation takes place of the same bloody serum. The tumour ought either to be opened its full length, and a pledget of lint introduced to prevent too hasty a union of the outer edges of the sac; or a seton should be intro- duced embracing the whole of the tumour, which should be suffered 280 ERYSIPELAS— WARTS IN DOGS. to remain for a week or ten days. By this means, instead of a discharge of serum, healthy matter will form in a little time 5 the sides will granulate and unite, and, on the removal of the seton, the external lips of the wound will close firmly and healthily. It is, however, a necessary caution to observe, that it is not prudent to open the tumour until it exhibits its charac- teristic shining appearance, with evident fluctuation. The future recurrence of the complaint must be prevented by attending to the constitution, as before directed. It is also proper to remark, that all the affections of the flap of the ear are greatly aggravated by the force with which they are rapped against the head by shaking it; the pendulous part should, therefore, always be secured in a kind of cap during the medical treatment. ERYSIPELAS. Dogs are subject to two inflammatory affections, not unlike to human erysipelas. The one attacks the head, and is described with Manse, and with Tumours also. The other affects the scrotum, and shews itself by a very red irritable state of the whole bag, which becomes swollen and excessively sensitive; some excoriation is also present, and sometimes actual ulceration ; and the poor dog finds it very painful and inconvenient to walk. In this state it should be fomented with poppy head infusion ; but no active mange application must yet be applied to it in this irri- table state, which would greatly aggravate it: the only ointment proper would be one made with acetate of lead, ten grains, and elder ointment an ounce. As soon as the irritation is abated, then proceed with it as mange. Both of these affections, being the offspring of plethora and too great fulness of habit, require de- pleting means to assist the external applications. WARTS IN DOGS. It is not uncommon for dogs to be troubled with warts on some parts of the body ; the most frequent instances of which are the lips, the penis, and the prepuce. These excrescences VERMIN ON THE SKIN OF DOGS. may be either cut off. or, when they exist in clusters, they may be sprinkled with equal parts of crude sal ammoniac and pow- dered savine ; which commonly effects their removal. VERMIN ON THE SKIN OF DOGS. As vermin are productive of mange, so the destruction of them is a very proper consideration in canine pathology. Ticks will adhere closely, and imbed themselves within the flesh ; these, it is common to pull away with the fingers, which often makes a dog shy of approaching his owner : if the tick be cut in two, it destroys it, and gives no pain to the dog. Fleas irritate many dogs almost to distraction, and render them obnoxious to their owners also ; and I hardly know a more frequent enquiry than, how to destroy them, and how they can be prevented from accumidating in the coat. Washing the body well with soap- suds, and directly afterwards carefully combing it with a small- toothed comb, are the most ready means of dislodging these nimble gentry. But it must be remembered, that the previous washing is only to enable the comb more readily to overtake them : the water does not destroy them ; for dogs who swim every day are still found to have fleas. These insects are very tenacious of life, and soon recover this temporary drowning ; the comb, therefore, is principally to be depended on for their cap- tion before they recover. But as washing is not, in many in- stances, a salutary practice, and as, in many others, it is a very inconvenient one, so it becomes a matter worthy of consideration how to be enabled to destroy them without these means. Sopping the skin with tobacco water has been recommended ; but it has only a momentary effect, and it not unfrequently poisons the dog. — See Mange. Innumerable other means I have tried to drive away fleas, but the only tolerably certain one 1 have discovered, is to make dogs sleep on fresh yellow deal shavings. These shavings may be made so fine as to be as soft a.s a feather bed ; and, if changed every week or fortnight, they 2H2 TREATMENT OP FRACTURES. make the most cleanly and wholesome one that a dog can real on ; and the turpentine in them is very obnoxious to the fleas. But, where it is absolutely impracticable to employ deal shavings, it will be found useful to rub or dredge the dog's hide, once or twice a week, with very finely powdered resin : if simply rubbed in, add some bran. CLASS XII. Surgical Operations on Dogs, fyc. TREATMENT OF FRACTURES. The limbs of dogs are very liable to become fractured; but the irritability of the constitution is so much less in these animals than in ourselves, that they suffer comparatively but little on these occasions; and the parts soon reinstate themselves, even without assistance, though in such cases the limb in general remains somewhat crooked. The thigh is a very common subject of fracture ; and though it appears a most serious bone to break, yet it is one that, with a little assistance, commonly unites straight, and forms a good limb. When a fracture has happened to the thigh, in case the violence has injured the fleshy parts also, so as to produce tension, heat, and inflammation, foment with vinegar and water until the swelling is reduced. When this is effected, apply a plaister of pitch or other adhesive matter, spread on moderately firm leather, sufficiently large to cover the outside of the thigh, and to double a little over the inside of it also. Then attach a long splent upon this, which, if it reach from the toes to an inch or two above the back, will be found to steady the limb very much. This splent. must be kept in its situation by a long bandage carefully wound round the limb, beginning at the toes, and continuing it up the thigh ; when it must be crossed over the back, continued down around the other thigh, and then fastened. This would, how- TREATMENT OF FRACTURES. 283 ever, slip over the tail, without other assistance ; for which rea- son it must be kept in its place by means of another slip passed round the neck and along the back. Fractures of the shoulder should be treated in a similar man- ner. lu fractures of the fore and hind legs, very great care is ne- cessary to insure a straight union. As soon as the inflammation and swelling will admit of it (sometimes there is little or none trom the first), apply an adhesive plaister neatly and firmly around the part ; then fill up the inequalities by tow or lint, so tbat the limb shall appear of one size throughout, otherwise the points of the joints will be irritated and made sore by the pres- sure of the splents. After this has been done, apply two, three, or four splents of thin pliable wood before, behind, and on each side of the limb, aud secure them in their places by a flannel band- age. In all fractures, great caution must be observed not to tighten the part, by either the plaister or bandage, so as to bring on strangulation of the vessels, which will be shewn by the swel- ling. Should this, therefore, occur to a considerable degree, the bandage must be loosened, or otherwise mortification may take place. In fractures of the fore legs, a supporting bandage, with side splents, should be kept on a longer time than is necessary for fractures of the hinder ones. If this precaution be not ob- served, the leg is apt to become gradually crooked, after the ap- paratus is removed. In cases of compound fracture, that is, where there is an open wound, which penetrates to the divided bones, the same means must be pursued as are practised in the human subject. Irritat- ing pointed portions must be sawed off ; the loose ones should be removed ; and every means must be adopted to close the wound as early as possible : during which process, the bones should be kept in contact with each other, and supported by soft bandages ; until the cicatrization of the wound will allow of proper splents and tighter bandaging. It likewise not unfrequently happens, that a compound fracture, or even a simple one, when neglected. 284 TREATMENT OF DISLOCATIONS. becomes united by a soft union ; that is, instead of the callus in- terposed between the divided ends being bony, it proves cartila- ginous only. In such a case the fractured bone never becomes firm ; but, on the contrary, when examined, an obscure motion may be felt, like an imperfect joint, which utterly precludes any strength in the limb. I have frequently been consulted on these cases, all of which have originated in the neglect of a proper attention to the fracture at first. The treatment here must be one of two kinds : we may either open the skin opposite the fracture, and, laying bare the bone, remove the soft portion interposed with a fine saw, treating the case afterwards as a compound fracture ; or we may insert a seton exactly through the soft cartilaginous portion, and keep it open ten days or a fortnight. After this time the seton should be removed, the wound closed, and the part treated as a simple fracture. Either of these plans will usually prove successful, and firmly consolidate the limb : but, when there is no lapping over of the ends of the bones, the latter is the most mild and con- venient, and equally certain of success. TREATMENT OF DISLOCATIONS. The joints most liable to this injury are the shoulder and knee before, and the stifle and hip behind. The first step is to examine whether there be a fracture also, which is frequently the case. Under these circumstances the treatment is rendered more com- plex, from the difficulty of reducing the dislocation, without using too much violence to the limb. The mode of detecting this additional evil is not difficult ; for if fracture is present, there will be an evident roughness and grating of the bones, which will be sensibly felt by the hand. When it is attempted to reduce a simple dislocation, it is evi- dent that the direction in which the dislocated bone is parted from its socket should be first taken into consideration in the means used for reducing it. A moderately firm extension should then be made by two persons; one holding the body and one CASTRATION. 285 part of the joint, and the other supporting the immediate dis- located limb, at the same time giving the luxated end a direction towards its socket. If this extension is sufficiently and properly made, the dislocated bone will slip into its place, and render the limb perfect. When the shoulder is dislocated from the arm, which is a rare occurrence, the disjunction may be forwards or backwards : it occurs generally forwards. The elbow may be dislocated either inwards or outwards; but it happens more frequently inwards, and it is seldom that it occurs without a frac- ture also. The hip joint is oftener dislocated than either of the former, and it is most common for the head of the thigh bone to be carried upwards and backwards, which makes the hip of that side sensibly higher and posterior to the other, and renders it easily detected. The muscles of the loins are so strong, that reduction of the thigh is always difficult; however, a firm and judicious extension will effect it. The hind-knee, or stifle joint, which is that next the hip, is the subject of dislocation; and it more frequently occurs inward than outward : this also, from the strength of the surround- ing muscles, is often found difficult to reduce ; and it is but seldom, likewise, that the elbow is dislocated without a fracture also. When a dislocation has been reduced, a pitch or other adhesive plaister should be applied around the joint to keep it in its place, which may be further assisted by a proper bandage. It may be useful to remark to the inexperienced practitioner, that he can no way detect the presence of either dislocation or fracture so well as by comparing the sound limb or joint atten- tively with the unsound one. CASTRATION. It now and then becomes necessary to perform this operation, from disease of the spermatic chord, or from scirrhous swellings in the testicles themselves. Whenever such a necessity occurs, although castration is not a dangerous operation on the brute subject, yet it requires the assistance of a veterinary or a human 286 S PAVING. surgeon. Each testicle should be taken out of the scrotum sepa- rately, by an opening sufficiently large, when a ligature should be applied, moderately tight only, around the spermatic chord, about an inch and a half beyond its insertion into the testicle ; the separation should then be effected by the scalpel or knife be- tween the ligature and testis. It is sometimes performed without the ligature, by making the division of the chord with a red-hot knife, but the other is the neatest and safest mode. It saves the animal much pain if the vas deferens be excluded from the liga- ture ; and it is very easy to do so. The castration of cats is sometimes practised to keep them from roving, or to increase their size. For this purpose nothing more is requisite than to make a slight opening on each side the scrotum, to slip out the two testicles, and draw them away with the fingers. The rup- ture alone of the spermatic chord prevents haemorrhage in them, and no future inconvenience is felt. It is often found difficult to secure a cat for this operation; but it may be easily managed in two ways : — one by putting the head and fore-quarters of the animal into a boot; the other by rolling his whole body length- ways in several yards of towelling ; but the former is the most secure and simple, for no animal is more intractable as a sur- gical patient than grimalkin : though to administer medicines to a pig, beats the cat hollow, as an obstreperous operation. SPAYING. This is so cruel an operation, that it should not be practised but when there is a real necessity for it : when it is done merely to convenience the owners, by preventing oestrum and breeding, it defeats its own purpose. There are, however, cases when it is actually requisite ; as when some peculiarity occurs that would prevent a bitch pupping with ease and safety ; or when she has been connected with, and is found to be pregnant by, a dog much larger than herself: in which case, as she would probably die in labour, it is not improper to remove the puppies in the third or fourth week of gestation. The operation is performed CANINE OBSTETRICS. 287 by making an opening in the flank of one side, when the ovaria, being enlarged by pregnancy, are readily distinguishable, and may be drawn out and cut off, first one and then the other ; securing the ends by a ligature lightly applied to each surface, but leaving- the threads without the wound, which is to be closed by stitches and bandaging. Farriers often apply no ligature, but content themselves with simply sewing up the wound, and no ill consequence seems to ensue. Bitches, after they have been spayed, become fat, bloated, and spiritless, and commonly prove short-lived: for Nature usually punishes any considerable devi- ations from her common laws ; and it is observed among animals, when the great work of propagation is artificially stopped, par- ticularly in the female, that, her sexual secretions failing to be rightly applied, and her reproductive organs remaining unem- ployed, the body becomes diseased. CANINE OBSTETRICS. DIFFICULT PUPPING. Great numbers of dogs die every year in bringing forth their young : a life of art has brought the human curse upon them, and they seem, in common with their female owners, to be doomed to bring forth in sorrow and pain. When bitches are at heat, great care should therefore be taken to prevent their intercourse with dogs much larger than themselves ; otherwise the size of the father influencing the size of the progeny, they become dispro- portionate to the parts of the mother, and she is often found un- able to bring them into the world : thus it is that cats, being all of nearly one size, seldom die in kittening. All dogs, that are much domesticated and confined, appear particularly subject to difficulty in bringing forth; consequently during pregnancy much exercise should be given, as nothing tends more to easy parturition than full exercise. Sometimes the constitution itself, in these tender and artificial breeds, is not equal to the exertion of labour; and sometimes false presentation increases the ob- 288 CANINE OBSTETRICS. struction. Whenever a difficulty in pupping occurs, which lias existed more than four or five hours, the bitch should be ex- amined by means of a finger passed up the vagina ; and, if any portion of a pup should be found to present itself, so as to be within reach of the finger, a skein of worsted ought, if possible, to be fastened around it ; and, during the throes or labour pains of the animal, it should be gently drawn away. If it cannot be reached in this way, a little longer time may be allowed ; but, after all, should it not advance, a pair of forceps may be used to assist the extraction. It is a good practice to give a laxative as soon as any symptoms of pupping appear ; and, when delivery seems much delayed, it will be prudent, in all cases, to bathe in warm water, and to give nutriment if the labour is protracted: occasional doses of laudanum united with asther must be given if any convulsive appearances come on. The patience of bitches in labour is extreme, and their distress, if not relieved, is most striking and affecting. Their look is, at such times, particularly expressive, and apparently imploring. A wish to relieve them has very frequently engaged me in performing the Cesarean operation ; but I never succeeded in any one instance. I attribute this failure, however, principally to the delay in the time, which humanity suggested ; and not to the nature of the operation altogether, which is, however, suffi- ciently dangerous. Whenever pupping is protracted considerably, the young are found dead ; and in those cases where they have been so for some time, from the effect of accident, they become the sure occasions of a protracted labour. The dead foetus often comes away piecemeal, sometimes many days after the natural time, and occasions a very foetid ejection until the parts have reinstated themselves. A very mild solution of the chloride of soda, thrown up the vagina, will sweeten the discharge, and hasten the expulsion of the remaining young. If the retention should be continued to a very dangerous length, the same might be given by the mouth with advantage, in very mild doses. From a wish to rear too many young ones, persons are apt to CROPPING. 289 overload the mother ; and thereby they often lose both parent and progeny. The mother seldom shews the effect of the overburthening at first ; but as the whelps begin to increase, and to require more supply, her constitution becomes impaired, and the usual marks of rapid exhaustion, convulsions, make their appearance. See this subject fully described, with the medical treatment of it, under the article Epilepsy. It is evident, therefore, that judg- ment should be exercised in this particular ; and that the mother should have no more young left to be suckled by her than her constitutional powers are equal to. Such as are strong, healthy, and have before brought up young, may find supply for four or five : delicate ones are sufficiently burthened with three ; many can only bear two : but in all cases feed the suckling bitch well, both for her own sake, and the future health, strength, size, and per- fection of form of the young. CROPPING. This custom is one that does not honour the inventor ; it may be readily asserted, that nature gives nothing in vain. Beauty and utili- ty appear in all, but in unequal degrees : in some, beauty is pre- eminent ; while in others utility appears to have been the principal consideration. That must, therefore, be a false taste which has taught us to prefer a curtailed organ to a perfect one, without gain- ing any convenience by the operation : the custom being, however, now fixed, directions are proper for its performance. Young dogs should not be cropped before the fourth or fifth week of their age : when the ears are cut earlier, they sprout again, and the form of the crop cannot be so well directed as when the ear is more deve- loped. It is a barbarous custom to twist them off by swinging the dog round, and the crop never succeeds so well as when made by scissors, which should be large and sharp. — In cropping terriers, begin at the hinder root of the ear, close to the head ; and when this cut is carried through, one other cross cut from the root at the front of the head, if managed with dexterity, will be sufficient, and will make an exci llent fox crop, without torturing 1 290 CROPPING, the animal with numerous trimmings. The less oblique the second cut is carried, the more sharp and foxy will the crop prove : the portion cut off, if laid on the remaining ear, will serve to direct the operation in that also. A rounded crop may be made at one cut. The cropping of pug puppies is the most painful of any; the cuts must, in general, be repeated, and carried close to the root of the ear; as upon the total absence of external ears (which gives an appearance of roundness to the head) is the beauty of the animal supposed to consist^. It is best to crop puppies in the absence of the bitch ; for it is erroneous to suppose that her licking the wounded edges does them good ; on the contrary, it only increases their pain, and deprives the young animals of the best balsam, the blood that flows from them. Rounding, which is a species of cropping, is also performed on pointers and hounds, both as a prevention and cure of the canker; but in rounding, only a portion of the flap is taken off. When this operation becomes absolutely necessary for the cure of canker, from all other means having failed (see Canker), care should be taken that the cutting may go beyond the extent of the ulceration, or the disease will return : when rounding is performed on a number of dogs, it is, in general, done with a rounding-iron. Tailing— When a dog is cropped, it is usual also to cut off a portion of the tail. Dog fanciers, as they are termed, commonly bite it off; but it were to be wished that a larger portion was added to both their knowledge and humanity. The tail does not grow materially after cutting, therefore the length may be pre- viously determined on with sufficient accuracy, and cut off with a pair of sharp scissors. If the ears and tail are cut off at the same time, it is prudent to tie a ligature about the tail, to prevent 19 It is not a little surprising that this cruel custom should be so invariably practised on pug dogs, whose ears are particularly handsome, and hang very gracefully. It is hardly to be conceived how the pug's head, which is not naturally beautiful, except in the eye of perverted taste, is improved by suffering his ears to remain. ■ WORMING. 201 Hie effusion of blood, as sometimes the bleeding, from both ears and tail together, will weaken the animal too much, and early distemper may follow ; but, when the tail alone is cut, no ligature is necessary. When a ligature is used, neither tie it too tight, nor suffer it to remain more than twelve hours. On the twisting off either the ears or tail, I will waste no invective ; for if the cruelty does not strike the performer, I am sure no assertion of mine, that it is far inferior in every point of view to excision, and has for ever deafened many it has been practised on, will be attended to. WORMING. This operation the veterinarian will probably be yet often called on to practise, and the sportsman may still for a few years indulge in the error of deeming it necessary for his dogs; it therefore finds a place here, although I am not certain but that my pages would have been more honoured in the omission than by the insertion of it. Method of worming dogs. — Secure a large dog on his back on a table, bench, or form ; one of a middling size may be held in the lap of an assistant ; a small one may be conveniently taken into that of the operator. The mouth being held open by means of two pieces of tape —one embracing the part immediately behind the upper, and the other, that posterior to the lower canine teeth — draw the tongue from the mouth, when, exposing its under surface, a cuticular fold or eminence will present itself, occupying its median line from the point to the base : open this with a lancet through its whole extent, which will expose a minute fibrous cord. Pass a blunt-pointed probe under it, and, carrying the instrument from one end to the other, detach the cord from its adhesions ; which done, divide it at one extremity, and carefully drawing it forwards, with a tenaculum, divide the other also. The uninitiated in sporting mysteries, may smile at all this mi- nuteness of detail, and recommendation of caution, in the division of a line of skin, and the extraction of a thread of ligament : T 292 WORMING. but all this is actually necessary to satisfy the prejudices of those - who put faith in the operation. For with them, it is essential to the prospective benefits of it, not only that the whole of tlie worm (for which read frsenum), should be extracted; but that, if possible, it should be done in one continuous mass. In the removal of this cord by huntsmen, game-keepers, &c, the violence used in stripping it off, puts its fibrous sub- stance so much on the stretch, that when extracted its elasticity making it recoil, gives it somewhat the character of the contrac- tion of a dying worm ; and we may yet read of this appearance, and its general form being adduced, as proofs of its vermicular identity. And although now no informed person gives credence to its being other than a portion of the canine tongue ; yet there are many sporting characters, of education and ability, who still lend themselves to an opinion, that there is some enigmatical property inherent in this part, which renders its retention dangerous ; by making the unwormed dog the subject of acute rabies, but the wormed one the subject of the dumb variety. Of a piece with this palpable error was that of Marochetti's vesicles in the same vicinage ; which being also with him the hiding-place of the rabid virus, it became as necessary, according to his doctrine, to de- stroy them, as it was with the ancients (and yet remains with some of the moderns) to remove the worm. Now, as Marochetti's alleged discovery originated with the Greeks, it would seem that the tongue was early destined to be considered, in one part or other, the particular seat of rabies. It has, however, fared very differently with these two errors ; for while the vesicles are almost entirely discarded from every mind, a certain connexion between this organ and rabies, modified, in- deed, from that of the ancients, indulged in before the time of Pliny (of the existence of an actual worm under the tongue)-0, yet 2" " La decouverte du Docteur Marochetti, cn supposant que e'en soit une, n'est peut-etre pas aussi nouvelle qu'on pourrait le penser ; du moins est-il reconnu que dupuis long-temps les Grecs tiennent que, lorsque quelqu'un a etc- mordu par un animal cnrag6, il se manifeste sous la langue, vers lc neuvieme jour, de petites vesicules designees sous le nom dc lysses, siegeant pres du frc in, et WORMING. 2<)3 still exists.

T 2 294 WORMING. of which, while it cannot cure the disease in the individual, or' prevent it, yet it can hinder his communicating it to others. I would fain hope that the description I have already attempt- ed of the rabid malady, will demonstrate that any state in which the tongue of the dog may be found, is not special; that it is only a state common to all the parts comprised in the fauces, pharynx, and larynx ; and also of the bronchia? and stomach. I have endeavoured to prove it a specific inflammation of all these organs, particularly affecting their nervous tissues; and which we know, by the symptomatic paralysis observed, and the morbid sympathies present. It is impossible, therefore, that all these parts can be generally affected, but that so large and so sensitive a contiguous and even continuous mass as the tongue, must receive its full share of the morbid derangement. We have seen that, in one variety of the disease, the respiratory nervous tissues seem to suffer particularly ; and that in the other (called dumb mad- ness) the digestive are principally affected ; in which case, the virus appears to act with more than ordinary violence on the whole alimentary track ; and, as might be expected, with the vast tumefaction which follows (in the fully formed stage of the disease, but not until then) ; the dog finds a difficulty in closing his mouth, with an effort sufficiently quick and powerful to bite. This state of madness being as common as the raging kind, it must frequently occur to dogs which have been wormed ; and when such is the case, the lessened danger from the swollen state of the mouth, and the actual diminished disposition to do mischief in this variety of rabies, is attributed to the worming : I, however, hope to be able to shew, that worming is most erroneously con- sidered a preventive against madness.
