PROCEEDINGS OF THE ROYAL IRISH ACADEMY, —— MONDAY, APRIL 11, 1864. Witiram Henry Harprnes, Esq., in the Chair. Alexander M‘Donnell, Esq.; J. J. Lalor, Esq.; the Hon. Thomas D’Arcy M‘Gee; and Sir Victor A. Brooke, Bart.; were elected mem- bers of the Academy. The Secretary read the following paper, by ALEXANDER MACALISTER, L.R.C.8. I., Demonstrator of Anatomy, Royal College of Surgeons: — On tHE ANATOMY OF THE OsTRIcH (STRUTHIO CAMELUS). THE science of comparative anatomy requires for its basis the records of the careful and minute dissections of at least the typical forms of the animal kingdom, in order that we may arrive at correct ideas re- garding the proper homologies and relations of the various parts of which the animate frame is made up; and though the subject of this memoir has been examined very frequently, there does not exist, to my knowledge, a complete or accurate account of its structural peculiarities. M. Perrault has left on record the dissection of eight of these birds; but in his description many interesting facts regarding the visceral anatomy are not mentioned, and the muscular system is not at all described. During the past year the splendid pair of ostriches belonging to the Zoological Society of Dublin died—the femalein June, 1863, from the constitutional disturbance consequent on a compound fracture of the metatarsal bone of the left lez; the male in January, 1864, from the effects of the severe and unexpected frost: both these animals have been dissected with great care, and many novel points of anatomical and . physiological importance have been ascertained in their structure.* * The female ostrich was dissected in the Museum of the Royal Dublin Society, and the male ostrich in the dissecting rooms of Trinity College. I am indebted to Dr. Carte and to the Rev. Professor Haughton for the opportunities I had of assisting in their ana- -tomical examination. R. I. A. PROC, —VOL. IX. B 2 They were both full grown and in good condition, the male being rather taller and fatter than the female. The integument, when removed, does not present the remarkable series of cutaneous muscles seen in the Apteryx; but a large number of superficial veins are discernible pass- ing around the roots of the feathers. The skin varies in thickness in several localities, but im general is strong and dense; on the neck it is tough and thin; on the breast and pubis it presents two callosities of — considerable size, on which the animal was in the habit of resting; on the dorsal aspect the tegument is thick and strong, and clothing the metatarsal bones it presents a series of large flat scales. Beneath, on the sole of the foot, the surface of the skin presents a series of closely set pristle-like processes, invested with a hard horny epithelium; these are about one-fifth of an inch in length, and would seem to serve in facili- tating the transit of the animal over the sandy soil of the desert. Under the skin is a fatty superficial fascia of very great thickness in some situations; over the abdomen in the female this adipose layer was two and a half inches thick, diminishing in thickness over the thorax, and ceasing altogether downwards on the thigh. The integuments and fat are closely connected to the bone over the sternum, in the region of the callosity, where the fatty matter has a granular appearance, similar to that on the sole of the human foot. This fatty layer is permeated by many very large veins, some of which can be traced to the pulp of the feathers. A thin and distinct layer of fascia separates the adipose structure from the muscles underneath, which were three in number— external oblique, internal oblique, and transversalis. The former arises from the lower borders of the ribs, and from a fascia which extends upwards to the vertebral column, and backwards to the brim of the pelvis; the fibres pass downwards and inwards to the mesial line, into which they are inserted for its whole length. The internal oblique, underneath the last, arises from the borders of the pelvis and lumbar fascia, runs forwards and inwards to the same insertion. The transver- salis commences by a strong flat aponeurosis from the spine and lower border of the last two ribs. This structure becomes fleshy for about two inches, and then forms an anterior tendon, which is inserted into the linea alba as far down as the symphysis pubis. The expanded tendons of these muscles attached to the spine form a strong lumbar fascia. Beneath these muscles lies an enormous fatty cushion, an inch and a half in thickness, and highly vascular; Perrault describes this as inter- vening between the abdominal muscles, but in reality it les posterior to them, and immediately over the peritoneum, which in our female bore the marks of inflammatory action, and exhibited extensive subja- cent ecchymosis. On the wall of the thorax are found two layers of intercostal muscles, separated by the intercostal vessels; the external run downwards and . forwards, and cease at the spurs of the vertebral ribs; the internal pass in a contrary direction, and only extend for three inches behind the spur on the vertebral ribs. A series of triangular levatores costarum pass from these spurs to the ribs below, extending as far forward as the arti- culation between the sternal and vertebral ribs; these and the internal 3 intercostals are in contact with the serous membrane lining the thoracico- abdominal cavity. The sternal ribs articulate with the vertebral by means of arthrodial surfaces, united by capsular fibres and a central in- ter-articular igament. On laying open the abdominal wall we disclose the viscera. The stomach is continuous with the lower end of the cesophagus, which exhibits at its lowest point a gradual dilatation, with no distinct proventriculus: this organ is placed obliquely, so that the cardiac orifice is on a plane inferior to the pyloric. The whole organ is an elongated oval in shape, and is not constricted in the centre; the thick- ness of its walls varies considerably,—the cardiac extremity being thin and membranous, the pyloric an inch and a half thick, and made up of al- ternating laminz of muscle and tendon: its epithelial lining is thick and soft, very loosely attached, except in the vicinity of the pyloric orifice, and much corrugated, the ruge being small, and arranged lineally in the long axis of the organ at the cardia, but larger and more irregularly convoluted at the pyloric extremity. This membrane has a decidedly acid reaction with litmus paper. The succenturiate gland is dumbbell-shaped, one broad extremity being placed at the cardia, and the other towards the pylorus; it measures four inches at its widest part, two at its constriction, and twelve in length; its orifices are arranged quincuncially, twenty-five to the square inch, and each communicates with a racemose gland. The pyloric orifice is much smaller than the cesophageal, and is semicircular in shape, its straight border being formed inferiorly by the tendinous wall of the gizzard ; the curve is formed of alternate firm ridges and grooves, the former six in number, the latter seven, and by this apparatus the pas- sage of undigested materials is retarded; this orifice is situated anteriorly, and between two radiating tendinous lamine. All the substances con- tained in the stomach, were of a dark green colour, as also was its epi- thelial coat; its contents were vegetable matters and stones in large quantities—the latter were rounded and worn. In the outer coat of the stomach of the female, and in contact with the gastric artery, a pin was found, enclosed in acyst. The intestinal canal seems to vary much in length. Hunter records finding it 70 feet, while Perrault, in his eight, states that it varied from 50 to 42, 33, and even to 29 feet; in our female the intestine measured 42 feet, and in the male 44 feet. The duodenum commences at the pylorus, is about three feet long, and passes very nearly in the course described by Hunter, first downwards, then turning and folding on itself, then passing from left-to right, then ascending till it crosses the spine above the ovaries in the female, and is retained in its place by piercing through the root of the mesentery ; at first, about three inches from its beginning, it receives the hepatic duct, and three feet lower the pancreatic. From the situa- tion where it escapes from traversing the root of the mesentery it is ac- companied downwards on cither side by a spiral-valved cecum, which is enclosed in the same layer of peritoneum, and lies about an inch distance from the gut; about 22 feet below, these caeca unite with the intestine, and from thence the colon passes downward rather narrower than the upper intestine ; its surface presents valvule conniventes like those in the small intestine of man, which are arranged alternately on 4 each part of the intestine, and pass three-fourths round the tube, project- ing half an inch inwards. These elongate the mucous ‘surface over which the food passes. This portion of the intestine was filled with hard fecal masses, containing whole corn and undigested food. The lowest part of the rectum passes from the right side downwards, and opens into the same side of the cloaca, inclining a little to the left; it projects into this sac for about half an inch, and is surrounded by a strong sphincter muscle embedded in its everted lip. The mucous membrane is longitudinally plicated, and the anus can be dilated to a considerable extent. The longitudinal fibres of the rectum are very distinctly marked, especially near its termination. The folds of peri- toneum which enclose the intestine are three in number: first, a short process which holds the duodenum in its place; secondly, a mesentery, in which is enclosed the intestine and ceca; and, thirdly, the portion which surrounds the lower intestine ; this latter extends across the spine obliquely from above, downwards, and to the right. In the second fold the mesenteric artery is traceable, and the lacteals, which pass upwards and backwards, and form a thoracic duct, which is seen to pass behind the vene cayee, and internal to the upper part of the right kidney, and to the right of the aorta; all these folds lie superior to the ovaries. The cloaca in the female is a large sac, admitting readily the whole hand; from its left side passes the oviduct, which is a large dilatable tube, capable of receiving four fingers and exhibiting longitudinal plicee on its mucous membrane; on the right side, and in a corresponding position, is a small cecal depression, but no duct. To the right of this and posteriorly the rectum opens at the top of the cavity, and between this aperture and the oviduct the mucous membrane forms a large cres- centic fold, its concavity looking downwards and backwards towards the external orifice; this appears to be capable of shutting off the rectum during the passage of an ovum, and wce versd. Behind the rectum and oviduct, in a small posterior pouch, open the two ureters very obliquely, one on either side, about an inch and a half apart, each admitting the little finger at their opening, but diminishing rapidly as they ascend ; — they are separated by a strong median ridge. Into the outer margin of the cloaca a strong levator cloacze muscle is inserted, which passes down from the posterior part of the sacrum and from the ischiatic ramus. A strong sphincter, an inch in breadth, en- circles the external opening. In the centre on the upper surface is a small pendent of cellular and erectile tissue, or clitoris, which displays a dorsal groove. The mucous membrane of the cloaca is arranged in longitudinal plates, so as to facilitate distention. In the lower part of the abdominal cavity in the female existed about two dozen ova, each enclosed in a separate sac or calyx, and all attached by a common pedicle about two inches thick to the posterior wall of the abdomen; by this the vessels pass into the ova, and ramify on the sur- face in a pectiniform manner, forming a vascular zone or girdle, the stigma of the ova. One of these ovaria, that had emitted its egg a few days before the animal’s death, appeared collapsed and dark coloured ; the others were light and yellowish, and from the size of a pea to that 5 of a large teacup. To the left side, and attached by a long distinct fold of peritoneum, in which are contained many arborescent vessels, lies the oviduct, beginning above by a bilobate, soft, gelatinous orifice in the peritoneal fold enveloping the ova, and descending and gradually widen- ing into a large ovisac; the whole tube is 22 feet long and opens by a narrow but dilatable orifice into the cloaca below. The interior of the lowest part was very gritty in feel, from the particles of carbonate of lime secreted there for the formation of the shell. The lowest part of the ovisac has a strong, well-developed muscular coat, which diminishes and almost ceases at the upper part. The kidneys are elongated, flattened, glandular masses, thirteen inches long, and an inch and a half wide, lying deeply seated, and extending from the posterior edge of the diaphragm to the anterior extremity of the pelvic cavity; they are brownish-red in colour, rough on the surface, and the left is divided into two lobes ; each is bordered by a large vein, which passes up to join the cava, posterior to which the ureter arises, at the junction of the inferior and middle third, from a well-marked pelvis, into which open several infundibula, which can be traced back to calyces. The medullary matter is not arranged in pyramids, nor do its tubes con- verge to papille. The ureter passes down approaching the mesial line, is reddish-white in colour, and cylindrical in shape. The renal artery is a branch of the aorta, and enters posterior to the ureter. The kidney is enveloped in a fatty capsule, which is very dense in front, and binds it down in its place, separating it from the ovaries. The supra-renal cap- sule is at its upper part, flattish-oval in shape, three inches long, and deep orange in colour; its inner angle passes considerably farther back than its external, and its upper surface is in contact with the diaphragm, There is no distinction of cortical and medullary matter in its structure. Superior to the kidney, on the left side, lies the spleen, enclosed in a layer of peritoneum derived from the stomach, and elliptical in shape, narrower above than below, the long axis being directed downwards, forwards, and to the right side; it is three inches and a halfin length by one in breadth ; it is surrounded by a capsule of peritoneum, and by a proper fibrous coat underneath ; it is supplied by a branch of the celiac axis, and is made up of a soft, spongy, vascular tissue of a deep red colour. The generative organs of the male consist of two testes, placed above and a little external to the kidneys, invested in a strong fibrous tunica albuginea, about three inches long and 12 inches in width; from the outer and back parts of these organs, the tubes pass to form a large epididymis, which is prolonged for three inches below the testis, and nar- rows into the reddish soft vas deferens, which runs down almost, parallel to the ureter, and opens into the cloaca a little external and anterior to it ; there is an elongated and pointed eminence, more than a quarter of an inch long, seen on the mucous membrane of the cloaca, and at the apex of it is the orifice of the vas; the opening of the ureter is much smaller in the male than what itisin the female. The two vasa deferentia open on either side of the groove in the intromittent organ, which com- mences by two firm fibrous crura attached to the pubis, then turns 6 downwards and backwards; when retracted, this organ lies at the bottom of the cloaca, curved; it has two muscles inserted into it, one at either side, which would serve to compress its texture. The dorsal groove terminates at its apex, where the investing membrane is red, and covered with a large number of sentient papilla. There are inserted into the cloaca a pair of long round muscles on either side, which do not appear in the female, and which are attached to the rami of the pubis. A very strong sphincter guards the orifice of the cloaca] sac. The pancreas is about ten inches long, and is included between the first two turns of the duodenum, and surrounded by peritoneum ; in colour it is pink, and is very soft, loose, and granular in texture ; from its centre passes the pancreatic duct, which commences in the gland by two branches, which unite before it passes from the gland substance; its duct opens into the second fold of duodenum, nearly three feet from the hepatic. The liver consists of two nearly equal lobes, the right being pro- longed a little lower down than the left; these lobes are separated above by the vena cava, which grooves the organ ; a falciform ligament also exists on the upper surface. The right lobe in the female exhi- bited an extravasation, and the capsule was very easily separated. No gall bladder existed. A small quadrate lobe exists behind the notch for the apex of the heart, and still farther back the outline of a Spigelian lobe is visible, separated from the former by a short transverse fissure, to which the lesser omentum is attached, and behind which is a large oval opening or foramen of Winslow. Through the transverse fissure the vena porta from the intestines passes upwards, and to the right a small branch or lesser porta pierces the left lobe. In front and to the left emerges the duct, which begins by three small branches, and passes behind the duodenum to the right, opening, threeinches below thestomach, into that intestine. The liver has two lateral ligaments, and many ves- sels ramify between the layers of the left. The large abdominal veins commence in the pelvic cayity, and pass forwards, one on either side, along the kidneys, grooving them as far as the middle of these glands, and lying about an inch apart; in this situation they bend inwards and unite, and then separate almost immediately, so as to form the figure of X; they still border the kidney, and unite at the upper edge of these glands, where the left one, the larger, passes over and joins the right; the vessels previous to this union receive the external iliac veins, and the femorals, which are separated from the femoral arteries by the kidneys, the latter vessel lying posterior. The cava ascends inclined a little to the right, comes in contact with the lower border of the liver, and passes in the sulcus between the two lobes, then receives the vense cavee hepaticee, and ends above in the right auricle. : In the thoracic portion of the somatic cavity the heart is seen in the centre, contained in the pericardium, a conical sac, the apex of which is very acute, and is directed downwards, and surrounded by the liver, be- tween the lobes of which it lies. This fibro-serous membrane is con- 7 nected posteriorly to the diaphragm, but partially separated from it by the cesophagus : on laying it open, the heart is exposed, with the great vessels starting from it. On the surface of the organ are seen the two coronary arteries, one arising behind the infundibulum of the pulmonary artery, and passing first between the left auricle and ven- tricle, then between the two ventricles anteriorly ; the other, arising from the aorta, opposite the right side of the pulmonary artery, and pass- ing in the posterior anriculo-ventricular sulcus, supplies the back of the heart, anastomosing with the last at the apex. The right auricle is a medium-sized cavity, with well-marked verti- cal musculi pectinati in its wall, and no appendix. The inter-auricular septum is thick, and separates the right from the smaller left auricle, which also presents strong perpendicular muscular bands on its wall, and is likewise devoid of an appendix. The two pulmonary veins unite and open into this cavity, on its posterior wall, by one common aper- ture, which is surrounded by a strong muscular band, which would be competent to close the orifice in a valvular manner. To the outer sur- face of the auricle several fatty masses are appended, like the appen- dices epiploice of the intestines. The right ventricle is a three-sided pyramid in shape when distended, smooth inside except around its edge, where there are a series of mus- cular trabecule ; its auricular orifice is oval, about 14 inch in its long axis, and guarded by astrong muscular valve, 14 line thick, situated to the rightof the foramen, and extending fortwo-thirdsaround it; astrong mus- cular band unites this to the anterior wall of the cavity, and strengthens its attachment. Numerous foramine Thebesiane exist on the inner sur- face of thiscavity. The orifice of thepulmonary artery is about two inches from the right auriculo-ventricular opening, and is guarded by three semi- lunar valves with indistinct corpora Aranti, and haying large sinuses of Valsalva behind them. The left-ventricle is strong, its wall being thirteen lines thick in several places, near the apex, however, it is extremely thin, in one spot only measuring two lines. The left auriculo-ventricular opening has a strong zona tendinosa and three membranous valves attached by cordee tendineze, but without distinct musculi papilares connected to them: carnese column are apparent near the apex of this cavity, but are not connected to the valves. The corde tendinece are very numerous, and pass transversely outwards from the walls of the cavity to the valves, the curtains of which are situated right, left, and posterior; the first is the largest, and is placed half an inch from the auricular opening. The aortic orificepresents nothing peculiar, butisprotected by three semilunar valves. Longitudinal rugze were visible in the liming membrane of the aorta in the female ostrich, with patches of atheromatous deposit. The aorta passes from its origin to the right side, and then curves backwards and to the left; this arch ascends for avery short distance, and about an inch above its origin from its convexity it gives off two arterle innominate, right and left, the latter being on a plane anterior to the former, and both lying on the trachea, in front of which and above the aorta lies a large round air cavity, about two inches and a half in 8 diameter, lined by a smooth cellular membrane, invested with a layer of epithelium, and presenting no distinct opening into it. The right inno- minate artery is about two inches and a half in length, forming a curve - concave to the right; it gives off the carotid and subclavian branches, the latter being small and passing outwards, the former ascending. ~ In connexion with the carotid artery is a large, brownish, glandular mass, about an inchin diameter, supplied by many arteries, and emitting a large number of veins: this and its fellow of the left side are the lateral lobes of the thyroid body without an isthmus. The left innominate is similar to the right in most respects. From the commencement of the subclavian a small cervical branch—the vertebral—passes upwards into the posterior portion of the neck. The pulmonary artery arises from the infundibulum of the right ventricle, is about two and a half inches long; and one inch and a half in diameter; it passes upwards, backwards, and to the left, and then divides into right and left branches. The trunk lies in front of the aorta, and its bifurca- tion corresponds to the front of the termination of the trachea. The right branch passes through the grasp of the arch of the aorta, is rather smaller than the left, runs downwards, backwards, and to the right side, lying above the right bronchus. The cardiac nerves of the right side run pa- rallel to its upper border as far as the anterior part of the root of the aorta, where they end in forming the coronary plexuses to supply the muscu- lar substance of the heart. The left pulmonary artery is larger, more an- ~ terior, and superior, than the right, but nothing of importance is discerni- ble in its course. The great veins are three in number—two superior cavee, and one inferior: the left superior cava is formed by the union of the jugular and subclavian veins with several smaller vessels from the thoracic parietes. This vessel lies posterior and external to the sterno-tracheal muscle, and internal to the furculum. The length of this vein before it is joined by the azygos is three inches, and this latter vessel unites with it just as it is passing into the pericardium, and an inch and a half from its entrance into the auricle. This vein runs downwards, backwards, and to the right side. The left vena azygos begins in the abdomen, at the upper border of the ovaries, passes over the diaphragm, and runs obliquely on the side of the pericardium, behind the left lobe of the liver, and terminates in the left superior cava. The right superior cava is double the size of the left, with which it corresponds in many points, its orifice being separated in the auricle from the inferior cava by a membranous valve, the great Eustachian, which guards the mouth of the latter: as this vessel is passing downwards, and to the left side, it receives the right vena azygos, a very small vessel, scarcely admitting an ordinary probe, which passes between the pleura and pericardium on the right side, and passes behind, and to the right of the auricle. The pulmonary veins are two in number, one on either side; the left is the longest, and is placed below the bronchus, and was in the female plugged up by a firm fibrinous coagulum. These-vessels coalesce as they approach the auricle. When these various organs are removed, a complex system of septa is exposed; of these there are five portions—one transverse, a | 9 fibrous structure, formed mainly of a fold of peritoneum, is placed across between the liver and the heart above, and the stomach and spleen below. ‘This fold is attached anteriorly and inferiorly to the lower edge of the sternum, and it unites with the tendinous lamina of the transversalis ; behind, this lamina is united to the diaphragm proper, which we shall describe subsequently. This portion is not, however, a complete septum. On removing the liver and heart, two large fibrous laming are exposed, covering the very large air sacs, which.occupy a large part of the thoracic cavity; these laminee send in four septa on either side, so as thus to subdivide the lateral portions of the cavity into — four compartments ; but the divisions are extremely loose and fibrous, so that each compartment freely communicates with its neighbour. In the centre of these compartments existed several peculiar oval bodies, like lymphatic glands in appearance, and in structure composed of an external rough, firm, fibro-cellular coating, with an internal yellowish- brown matter of sebaceous consistence. These were about an inch long, three-fourths broad, and one-fourth in thickness, and were arranged in a line on each side, connected to the septa by ten or twelve threads, radiating in all directions. Beneath these bodies and the air sacs, we find a true muscular diaphragm, composed of a flat tendinous central lamina, and two lateral fleshy portions, concave in front and below, convex above and behind ; it is attached on either side by five fleshy slips to the five lower vertebral ribs along their margins; the fibres run backwards and in- wards to the tendons, and some. pass a little upwards, and are about 24 inches in length. The kidney reaches to its lower border, and the spleen lies on its inferior and posterior surface. The cesophagus pierces it in front, and lies below it for a considerable distance; the two lower muscular fasciculi are separated from:the upper by a large aperture, looking down- wards, forwards, and outwards, which led to the air sac from the bronchial tube. Two other large openings exist, one on either side of the cesophageal orifice, which pass downwards and backwards; and above, and external to these, are two smaller holes, running in the same direc- tion; the two lower slips of muscular fibres are broad and flat, and the upper are round and thick. The aorta passes through the lower border of this true diaphragmatic structure, and on either side of it passes down a tendinous slip or crus, to be attached to the sides of the bodies of the lumbar vertebree. The lungs are exposed on removing the diaphragm, and appear placed at the upper and back part of the cavity of the thorax, filling the spaces around the heads of the ribs; into these organs pass the bronchial tubes, one along the centre of each lung towards the base, the right being more transverse and more curved than the left. These tubes are membranous, and communicate with the air sacs by means of the open- ings in the diaphragm ; allits branches come off mm a regular series from its posterior surface, and the trunk ends below by communicating with a large air sac, which lies on either side of the back of the abdominal eavity; this latter is similar in structure to the thoracic series of air cavities. The branches of the bronchus appear pinkish, and seem mus- RB. I. A. PROC.—YVOL. IX. c 10 cular, and are arranged in a row of eight or nine large holes, with an | alternate series of smaller holes externally ; a double row exists on the right, but a single series on the left. The air sacs communicate with these bronchi. The lungs are separated from each other by the aorta, which passes down inclining to the right side, and pierces through the diaphragm opposite the lowest border of the last thoracic rib; a tendi- nous arch passes over it at this point, below which the cceliac axis arises. This trunk is about 14 inch long, and gives off gastric, hepatic, and splenic branches ; around it is arranged a sympathetic solar plexus, and from its root start the diaphragmatic arteries. The superior mesen- teric artery arises an inch below and to the right of the last, and supplies the intestines. The femoral artery arises from the aorta, three inches below the superior mesenteric; it is a small trunk, runs outwards, and divides into a proper femoral and an external iliac, which passes along the brim of the pubis as far as the symphysis; below the origin of this vessel the aorta, or sacra media, continues downwards behind and between the kidneys, and immediately behind the vena cava, from which it is separated by a delicate fascia. A large sciatic branch passes off through the sciatic notch, and accompanies the sciatic nerve, becoming popliteeal behind the knee; still lower, a series of renal vessels arise on either side, and from the anterior aspect of the aorta the ovarian vessels of the female start. At the lower border of the kidney the aorta bifur- cates; each lateral branch, about two inches lower down, again divides into two, which again split in a similar manner, so as to form a series of eight tertiary branches, which terminate, behind the cloaca, in the pad of the tail, for the nutrition of the plumes. In the neighbourhood of the tail there exist the following muscles :— Levator coceygis, which arises from the lower part of the sacrum, about two inches in extent; the fibres pass downwards and backwards, form- ing a series of roundish muscular fasciculi, which are inserted by round tendons into the seven caudal vertebre as far as the last. Between this pair of muscles are seven depressions, corresponding to the foramina in the vertebree. Coccygzeus arises from the side of the lower half of the coccygeeal vertebre, forms a triangular mass, running to be inserted into the pad of the tail. There is no sign of an oil gland in this locality. Depressor coccygis is a small muscle, passing from the bodies of the upper to the last caudal vertebre. The muscles of the back form a small and not very distinctly deve- loped series. On raising the integument and fat, we bring into view the first or latissimus dorsi, which arises tendinous from the spines of the three or four upper dorsal vertebre. The fibres run downwards and outwards, to be inserted into the inner edge of the upper third of the humerus and fascia of the wing. Rhomboideus major, beneath this, arises from the fascia at the upper and back part of the thoracic wall, passes forward to be inserted into the blade of the scapula along its posterior border. Rhomboideus minor is above the last, and has a tendinous origin from transverse process of the last cervical vertebra, from which it passes 11 downwards, and is inserted into the scapula above the last named. Be- neath these rhomboids exists a deeper muscle, also of a rhomboid shape, which is attached to the necks of the first and second ribs, and is inserted near the point of the blade of the scapula. Serratus is a small, thin, square muscle, arising by an aponeurotic expansion from the lower edge of the upper ribs; the fibres pass down- wards and backwards, and are inserted into the anterior border of the scapula, below the origin of the teres minor. Semispinalis dorsi, or sacrolumbalis, arises from the upper border of the posterior portion of the crest and dorsum of the ilium, and from the sides of the lower vertebre, by fleshy fibres, which pass forwards and a little outwards, to be inserted into the angles of the five upper ribs by tendinous and fleshy fasciculi. Lying internal to this we find the longissimus dorsi, attached below to the posterior and inner half of the crest of the ilium, and to the sides of the lumbar vertebrae; the muscle runs upwards and forwards, and at the lower part of the neck divides into several fasciculi, which run to be inserted into the sides of the transverse processes of the four lower cervical vertebra : the most inter- nal band continues upwards, to be attached to the five or six upper cervical transverse processes, and to a pit above the foramen magnum on the occipital bone. This muscle seems to consist of several portions which in other animals are distinct. Levatores costarum posteriores, seven in number, arise tendinous and fleshy from the transverse process of the seven upper dorsal vertebree, and run outwards and backwards, to be inserted into the outer surface of the ribs as far as the angle; their action is to elevate or fix the vertebral ribs. Spinalis dorsi passes from the lower to the upper dorsal spines, but seems not to be attached to any regular number of vertebra. Scalenus—a small triangular mass—arises from the posterior tubercle of the transverse process of the last cervical vertebra, and is inserted into the upper border of the first rib, close to its vertebral articulation. Multifidus colli consist of many slips, which pass from the anterior tubercles of the transverse processes on the sides of the cervical vertebrae to be inserted into the prominent tubercle on the middle of the anterior aspect of the body of the vertebra above. There is also a posterior set of these muscles, which run from the posterior tubercle of the transverse process of each vertebra to the spinous process of the vertebra above. A thin biventer cervicis may be found, arising by an aponeurosis from the dorsal vertebree, and inserted along with the longissimus dorsi. On the front of the thorax, the great pectoral is seen—flat, thin, fleshy, and triangular—arising from the outer edge of the sternum and the three upper sternal ribs, aud passing outwards to be inserted into the ridge on the upper and outer parts of the humerus below its head. When the integument is removed from the face, a series of facial muscles are exposed, principally connected with the eye, which is suarded by two nearly equal lids, whose edges are beset with stiff, everted hairs, longer on the upper than on the lower lid. Transverse fibres run into the substance of the lower lid, like the remains of an orbicularis 12 palpebrarum, the use of which seems to be, to elevate the lower lid; pos- terior and superficial to it is a venous plexus, formed of the veins of the head and face uniting to form a single trunk, which passes to the jugular vein. A strong palpebral ligament extends from the brim of the orbit all round into the lid, to strengthen it. Levator palpebree superioris arises within the orbit, from the bony surface forming the posterior portion of the roof of the cavity ; the fibres run outwards, and are inserted into the tarsal border of the lid. A small anterior bundle of muscular fibres passes from the inner or anterior angle of the orbit to the inner can- thus of the lids; this seems to be also an elevator of the upper lid. The orbit contains the recti, obliqui, and the two muscles of the membrana nictitans: the former arise around the border of the optic foramen, united by a hgament of Zinn, stronger above than below. ‘The muscles of the membrana nictitans are, as usual, quadrate and triangular ; nothing of peculiarity is noticeable in their arrangement, except that from their greater size they are better seen than in most birds. They are supplied by the third nerve, and the tendon of the triangular muscle grooves the sclerotic posterior to the bony plates. External to the trian- gular muscle, and between the inferior and internal rectus, is placed a large oval Harderian gland, embedded in cellular tissue, and compressed, pro- bably by the triangular muscle when acting, so that its secretion 1s forced out, and is conveyed by a duct to the inferior and inner border of the attachment of the membrana nictitans. A peculiar gland is found embedded in the depression on the side of the frontal bone, separated from the nose by a strong membrane, through which its duct seems to penetrate. All the parts in the orbit are surrounded by the layers of a loose ocular fascia. There are two elevators of the lower jaw, closely connected. Tem- poral arises from the deep fossa behind the orbit, and is inserted into the coronoid process of the lower jaw; the other lies more horizontally, and arises posterior to the last from the hinder portion of the temporal fossa, almost as far back as the occipital bone; from this origin it passes downwards and forwards, to be inserted into the ramus of the lower jaw in front of the coronoid process, here overlapping the last. A large glandular mass fills up part of the interspace between these muscles, in contact with the forementioned venous plexus. In dissecting the neck, a large platysma is first seen, which below is attached to the furculum, and above to the integument, as high as the head ; its outer fibres are oblique, and the inner vertical; it is thicker and stronger in front than behind ; beneath it, at the upper part of the throat, is the larynx and its muscular apparatus, and in our dissection we meet with the following :— Mylo-hyoid—flat and triangular—arising from a ridge on the anterior four-fifths of the lower maxilla, in contact with the mucous membrane of the mouth; the fibres pass inwards, and are inserted along with the opposite muscle into a median raphe; a few of the most posterior are attached to the os hyoides. Maxillo-keratic is a long flat slip, passing from the lower jaw a little 13 in front of its condyle, to be inserted into the concavity of the great cornu of the os hyoides, round which it winds. A small muscular slip runs from the great cornu of the os hyoides on one side to the opposite, probably acting as anapproximator. Genio-hyoid—flat and straight—runs from the lower surface of the centre of the lower jaw, passing backwards to be inserted into the body and root of the great cornu of the os hyoides ; beneath this pair is the upper quadrilateral projection of the os hyoides, continued into the very short tongue. Hyoglossus, a very short muscle, passes from the sides of the body of the os hyoides, as far forwards as to the tip of the tongue. Numerous small muscular slips exist on the anterior aspect of the larynx: one—hyo-laryngeus—passes from the back of the os hyoides to the upper border of the thyroid cartilage, and several small transverse slips unite the cornua of the thyroid cartilage. Thyro-hyoid—small, trans- verse—passes from the oblique line on the front of the thyroid cartilage, to be inserted into the great cornu of the os hyoides. Sterno-tracheal—three feet and a half in length—arises from the posterior surface of the top of the sternum by around muscular slip, which is reflected inwards on the side of the trachea, three inches above its bifurcation ; from this point the muscle passes upwards, being adherent to the cartilaginous rings as it ascends, the fibres expand, and finally are inserted into the lower border of the thyroid cartilage, some passing as far as the os hyoides. On the side of the thyroid cartilage a small muscular slip passes to the back of the os hyoides. In the substance of the tongue a few longitudi- nal muscular fibres or linguales can be traced on either side of the middle line. The upper larynx exhibits two vocal cords, which are more than half cartilaginous. There is no epiglottis; the muscles seated here are prizcipally the proper arytenoids and posterior dilator muscles ; a pair of thyro-arytenoids may also be seen. There is no lower larynx. The trachea is made up of complete cartilaginous rings, forming a tube three feet nine inches in length, behind which lies the cesophagus, with a plicated lining membrane, which begins above in a dilatation or pharynx ; on either side of the upper part of this sac les a large glandular mass or tonsil, opening by several ducts, which communicate with racemose gland cavities. The jugular vein, which lies in front of the carotid artery, passes posterior and external to the cesophagus; the arteries lie close together, but do not communicate. In removing the upper portion of the skull, in order to expose the brain, the bones are found extremely spongy, and united at the sutures. When they are removed, the encephalon is brought into view, invested with a dura mater, arachnoid, and pia mater. The former is strong, and does not present more than the rudiment of a falx; and the latter is found passing into the ventricles on either side, forming a choroid plexus. The cerebrum exhibits no convolutions on its surface, and is made up of two hemispheres and two tubercles or optic lobes. The cerebellum lies pos- terior and inferior to the cerebrum; and the medulla oblongata is a central prominence, exhibiting no secondary subdivisions, connecting the spinal marrow below with the encephalon above. The cerebellum consists of 14 one large central lobe, marked out into a series of transverse lamelle by fissures or involutions; to either side of it small lateral lobes are appended, and in section it presents a distinct Arbor vite. No pons varolii seems to exist even in rudiment. The carotid arteries ramify on the surface of the organ, and the vertebrals pass on the side of the medulla oblon- gata. From the base of the brain pass the cerebral nerves. The first, or olfactory, runs to the nose, under a bony shelf, from the anterior and inferior portion of the cerebrum, where a small conical eminence is observable; it is extremely soft and somewhat greyish atits origin. The second, or optic, arises from the optic lobes, curves downwards and for- wards, and meets in front of the infundibular fold of pia mater with its fellow of the opposite side; the decussating fibres are easily seen at the commissure. The third and fourth nerves pass to the orbit, where they supply the muscles; they arise between the medulla oblongata and the posterior cerebral tubercles. The trifacial nerve is very small, and has an extremely small supra-orbital branch. The eighth pair sends off a large glosso-pharyngeal to the tongue, along with a glossal branch of the pneumogastric. None of the other nerves display any points of interest. On removing the upper part of one of the cerebral hemispheres, the large lateral ventricle is exhibited, closed internally from the median fissure by a thin plate, white on the ventricular, and grey on the inter- nal aspect. This plate is connected with the opposite side by a narrow white band, easily torn, and situated far back, not far from the posterior cerebral tubercles ; this seems to be similar to the band described by A. Miiller as a rudimental corpus callosum. Lach lateral ventricle consists of one part, and presents no cornua; it has two large grey masses on its floor—one large, anterior, the corpus striatum; another smaller, posterior, the optic thalamus, separated by a rudimentary tenia; overlapping the thalamus is a large fold of pia mater, which gains entrance posteriorly ; this is the choroid plexus. Posterior to the cerebral hemispheres appear the optic lobes or tuber- cles, which are covered by a layer of pia mater, enclosing a small oval pineal gland ; these tubercles are hollow, and their cavities communicate with the lateral ventricles ; in front of them passes a posterior commis- sure, which overlaps a large iter ad quartum ventriculum, or Sylvian aqueduct. The fourth ventricle is placed anterior and inferior to the cerebellum, and presents a very well marked calamus scriptorius. The spinal cord is fissured deeply in front and behind, and is enveloped in three membranes; each spinal nerve arises by two roots, of which the anterior is much the smaller; these pass separately through the dura mater, and unite outside the foramina of conjugation of the vertebree, the posterior forming a ganglion which the anterior crosses, and the two roots are united immediately external; a branch of the sympathetic can be traced to each ganglion. The roots of the spinal nerves are not sepa- rated by a ligamentum denticulatum, but pass obliquely downward and outward, converging. The sympathetic is a small cord, passing along the spine, behind the aorta, and forming a solar plexus around the cceliac axis. 15 The dissection of the extremities, both anterior and posterior, pre- sents very many points of importance. Of late years, from the many interesting questions arising out of the subject of the origin of species, it has become a point of extreme importance that comparisons should be instituted between the development of similar structures in different animals, or diverse parts of the same animal, in order that we may arrive at correct ideas of homology. Now, inthe ostrich we have a bird with terrestrial habits, and bearing a resemblance in the arrangements of its muscles to the mammalian class of animals; consequently it is of immense importance to have a correct idea of the position and nature of the muscles in his limbs. The branch of comparative anatomy which treats of muscles has been very much neglected of late, although there are as interesting considerations and as difficult problems involved in myology as in neurology or osteology. The upper extremity, or wing, in the ostrich is very small, and per- fectly incapable of flight; the prolonged humerus forms a very large portion of it. We find in this limb, however, the homologues of most of those muscles which are of use in those birds which are fitted for aérial locomotion. Coraco-brachialis forms an elongated fleshy muscle, arising from the outer third of the inferior edge of the coracoid bone, about two inches from its sternal articulation, it passes downwards and backwards, to be inserted into an oblique line on the inner side of the humerus, running downwards as far as about four inches below the head. Biceps—a long, thin band—arises, by a distinct round tendon, from the coracoid bone, above the coraco-brachialis, and also by a distinct slip from that muscle. The fibres pass down straight, and are inserted by a tendon, which runs on the surface of the muscle for a short distance, into the tubercle on the inner side of the radius. This muscle is covered by a large cephalic vein, which runs from the outer side of the fore-arm to the inner side of the axilla, and terminates in the axillary vein. Covering the outer surface of the foramen which exists between the coracoid and clavicular apophyses, is a triangular fleshy mass, with its base inwards. This muscle Professor Haughton has suggested, and apparently with good reason, to be the second pectoral of birds. Its fibres arise from the borders of this aperture, which it blocks up, and run outwards, becoming tendinous. The tendon passes in a groove over the head of the humerus, winding round a trochlear surface, to be in- serted into the outer part of the great tuberosity. The function per- formed by this muscle evidently seems to be the elevation of the wing. A hurried glance at the combined coracoid bone and clavicle cannot fail to suggest to the mind the appearance of the anterior part of an os innominatum, of which the former represents the ischiatic segment, and. the latter, the pubis. The resemblance is extremely striking between the obturator foramen and this aperture in the bones of the scapular arch. May we not, then, consider the muscle closing this as the ho- motype of the obturator, mm the anterior extremity, and thus conclude that the second pectoral in the fore is homotypical with the obturator externus in the hinder limb? : 16 The subscapular muscle is divided into two portions: a superior, small, triangular, passes from the thoracic aspect of the coracoid bone, and upper part of the scapula, to be inserted into the inner tubercle, at the upper extremity of the humerus. The inferior portion arises from the posterior border of the scapula; the fibres run outwards, to be in- serted by a twisted tendon below the last. Deltoid—a triangular muscle—arises from the posterior border of the scapula, behind the humeral joint, by a flat tendon; it passes down- wards and outwards, becoming fleshy, and is inserted into the ridge on the back of the humerus, as far down as to within three inches of the humero-cubital articulation. Teres minor passes from the border of the blade of the scapula to the lowest point of the tubercle of the humerus. Extensor cubiti con- sists of two heads—one long, arising from the lower border of the sca- pula, between teres and deltoid; the second, or inner, from a ridge on the inner side of the humerus, as far down as an inch from the cubital joint; the two heads unite low down, and clothe the back of the hu- merus, and are inserted into the olecranon process of the ulna and fascia. Brachialis anticus arises from the lower half of the anterior surface of the humerus, passes under the pronator teres, to be inserted into an oblique ridge on the front of the ulna. Pronator teres runs from the internal condyle to the outer side of the radius, and passes over the radial artery. Flexor digitorum communis arises from the anterior surface of the ulna, as far down as the lower extremity of that bone. The fibres end in small tendons, which are inserted into the second phalanx of all the digits. ” Flexor carpi ulnaris passes from the inner condyle of the humerus, and the external part of the ulna, to the pisiform bone of the carpus. Supinator longus arises from a ridge above the outer condyle, and is in- serted into the metacarpal bone of the thumb. The musculo-spiral nerve runs between this muscle and the brachialis anticus. Supinator brevis, beneath the last, runs from the outer condyle and external la- teral ligament, to be inserted into the upper and outer part of the radius. Extensor carpi radialis arises from the posterior surface of the radius, and runs to be inserted into the outer metacarpal bone. Extensor digitorum communis passes from the external condyle into the last phalanges of the inner digits. Extensor carpi ‘ulnaris arises from the back of the outer condyle, and from the posterior surface of the ulna, for its whole length, and is inserted into the base of the outer metacarpal bone. Indicator passes from the interosseous space, and the side of the ulna, and ends in a tendon which passes to the index finger. There are two interossei on the front of the metacarpal bones, and one on the dorsal aspect. A small abductor minimi digiti runs from the pisiform bone to the metacarpal bone of the third finger; and a still smaller abductor pollicis is attached to the outer bones of the carpus, and inserted into Jaf the first phalanx. The small subclavian artery, about the size of a crow- quill, runs between the clavicle and first rib, and so passes down to nourish the upper extremity. But, as the great characteristic endowment of the ostrich is its enormous power of running, we find that the muscles of its hinder limbs are those which are pre-eminent in point of development; these are exposed when the integument and the subjacent strong fascia are raised. Under the skin in the thigh, two large veins, an external, and an inter- nal saphena, are traceable. Covering the whole of the posterior part of the hip and thigh, an enormous, triangular, flat, fleshy muscle is brought into view, which seems to consist of three parts—the upper third, or tensor vaginee femoris, the middle, or gluteus maximus; the inferior, or the depressor caudee ; the whole mass arises from the posterior edge of the uium as far forwards as the commencement of the symphysis iliaca, and as far backwards as the side of the tail. The tensor vagine femoris runs forwards, downwards, and outwards, converging to form a flat tendon, which passes over the anterior and external surface of the knee, where it unites with the anterior and lateral heads of the gastrocnemius, and partly is inserted into the head of the tibia along its anterior edge; the middle third, or gluteus, is inserted along with the last, and by a small musculo-tendinous slip unites with the vastus externus beneath. The depressor caudee is hardly separable from the posterior border of the gluteus maximus, and is inserted into the lowest border of the tendons of the two upper portions. On removing this enormous covering, the deeper muscles are exposed. Sartorius—a square, thick mass—arises from the outer side of the upper and anterior part of the ilium, and from the spines of the lumbar verte- | bre; the fibres run downwards, forwards, and outwards, to be inserted in- to the side of the ligamentum patelle, and the upper portion of the inner condyle of the tibia, and by a fascial expansion to the inner condyle of the femur. Gluteus medius—a triangular fan-shaped muscle—arising from a large space on the ilium, almost the whole of its external surface as far back as the acetabulum; the fibres converge, and run outwards to form a flat tendon, which is inserted into a pit on the upper and outer part of the great trochanter. The tendon passes over a bursa on the summit of the trochanter, and is attached to the origin of the vastus externus. The tendon of this muscle commences between two planes of muscular fibre. Gluteeus minimus is a small pear-shaped muscle, arising from the upper and anterior portion of the illum, superior and anterior to the acetabulum ; its fibres converge, run backwards and outwards, and are inserted into the anterior ridge at the root of the great trochanter, posterior and inferior to the gluteus medius, and beneath a tendinous arch, formed by the origin of the vastus externus. Opponens quadrato- ‘femoris, or ilio-capsular, is a remarkable, well- marked, triangular, fleshy slip, arising from the ilium, anterior and infe- rior to elutzeus medius, and superior and anterior to the eluteus minimus; the fibres run outwards, to be inserted into the same line as the last named muscle, and are united to it by a tendinous slip. The nature of the homo- R. I, A. PROC.—VOL. IX. D 18 logy of this muscle does not appear at first sight very distinct; but it seems to agree with the muscle described by Harrison as the ilio-capsular, which rarely though occasionally occurs in man; and Dr. Wilson has suggested to me that it may be the homotype in the hinder limb of the supraspinatus in the upper extremity. The gluteal artery, nerve, and vein, separate it from the gluteus minimus, and pass directly backwards to supply the muscles of the hip. Thlacus is a triangular muscle, arising from the part of the iliac bone directly under the gluteus medius, and between the gluteus minimus and opponens muscles; it passes downwards and outwards to be inserted into the lower part of the neck of the femur and lesser trochanter, un- der the crureus. The sciatic artery passes along with the sciatic nerve downwards to form the popliteal, as the femoral artery 1s small, and only supplies the front of the thigh. The femoral vein and artery are separated by the crural nerve. Crureus—a large oval muscle—arises tendinous and fleshy from the point of the great trochanter, and from the lower two-thirds of the anterior surface of the shaft of the femur; the fibres run forwards, and are inserted fleshy into the upper border of the patella on the inner side, and by a tendinous expansion into the anterior edge of the head of the tibia. Vastus internus muscle is composed of two parts, a superficial and a deeper seated; the former arises from the pos- terior and internal side of the femur, and from the linea aspera as far as to within two inches of the condyle; the second portion arises from the anterior and inner side of the bone, andis distinct from the former part, which overlaps it; the fibres of both muscles unite below to form a twisted tendon, which is inserted into the inner side of the head of the tibia, into the inner edge of the patella and the ligamentum patelle. Vastus externus is likewise divisible into two planes of fibres: the superficial, strong, oval, fleshy and tendinous, arises from the outer sur- face of the great trochanter, and from the upper part of the external division of the linea aspera and the rough surface at the upper and outer part of the femur for two inches and a half from the point of the tro- chanter; the fibres pass downwards and forwards to form a flat tendon which is inserted into the capsule of the knee, into the upper border of the patella, and by a tendinous expansion into the external side of the tubercle of the tibia; this tendon is connected to the origin of the gas- trocnemius, and overlaps the tendons of the glutzeus medius and minimus. The deeper plane of fibres arise from the ridge on the external surface of the femur, and forms a fan-shaped tendon, which is best developed along the posterior edge; a flat tendinous band passes from its deep surface to the outer edge of the tubercle of the tibia, ranning downwards, backwards, and outwards, along with the external lateral ligament, and connected to the outer origins of the flexor muscles; the rest of it is inserted, with the superficial part of the vastus, into the patella and tubercle of the tibia. ae Rectus femoris arises fleshy from the anterior spine on the iliac bone, three inches in front of the acetabulum; it forms a strong oval belly, which ends in a flat tendon, which soon becomes rounded, and passes —_ 1S) over the anterior surface of the patella in a deep groove, which is directed downwards and outwards, underneath the outer head of the gastroc- nemius; it then passes underneath the vastus externus and biceps tendons, becomes fleshy, and forms one of the origins of the flexor digitorum magnus: the length of this whole muscle, with its lower belly, is five feet. On the back of the thigh are arranged the following muscles :— Biceps—alarge fleshy muscle—arises from all that part of the prolonged inferior spine of the ilium as far forward as the acetabulum, and separated from the inferior edge of the bone by the origin of the semimembranosus. In the female a small slip existed, attaching it to the posterior surface of the femur, which did not appear in the male. The fibres converge to a strong round tendon, which passes through a pulley, formed by the outer head of the gastrocnemius, and lined by a synovial membrane, and is inserted into the tubercle on the middle of the fibula: this muscle forms the external boundary of the popliteal space. Semitendinosus—long, flat, and triangular—arises by two fleshy slips from the extremity of the posterior inferior spine of the ilium, and from the tuber ischii and the great sciatic ligament; the fibres converge, and are inserted into the upper and back part of the inner side of the tibia and tibial fascia; an accessory muscular slip connects this tendon with the insertion of the adductor magnus and the shaft of the femur. Semimembranosus arises from the inferior border of the posterior in- ferior spine of the ilium, and from the border of the great sciatic hgament; the fibres are inserted into the lesser trochanter of the femur, and into a fascial line as far as the inner condyle. A slip from its origin in the female was attached to the side of the caudal vertebre. On the inner side of the thigh are arranged the following muscles :— Obturator—a large, ovoidal, tendinous, and fleshy mass—arises from both the inner and outer surface of the rami of the pubis and ischium ; communicating through the obturator foramen ; all the fibres pass in the direction of the long axis of the pelvis, converging towards the lesser sciatic notch, which is almost entirely osseous, and is placed at the junction of the ischium and ilium ; here it becomes tendinous, and passes outwards and a little backward to be inserted into the outer and upper part of the great trochanter. Its action is determined from the trochlear surface of the notch or foramen over which it winds, which is invested with synovial membrane ; within the pelvis it lies along the border of the kidney. Gemellus superior—flattish, small—arises from the anterior edge of the lesser sciatic notch, and is inserted by a thin flat tendon into the great trochanter in front of the obturator. Gemellus inferior—smaller than the last—passes from the hinder margin of the lesser sciatic notch to the trochanter, behind the obturator tendon. These three muscles run in contact with the synovial mem- brane of the hip, as the capsule is very imperfect beneath. Pectineus—a small flattish muscle—arises fleshy from the upper fifth of the ramus of the pubis, and from the pectineal eminence; the fibres run forwards, downwards, and outwards, becoming tendinous, to be in- 20 serted into the external part of the upper extremity of the tibia, imme: diately below the knee. Gracilis arises by a flat tendon, about five inches long, from the ramus of the ischium and sciatic igament; the fibres converge, and are inserted below the knee into the inner edge of the tibia, below the con- dyle, and into the fascia of the leg. Adductor magnus arises fleshy from the posterior border of the ramus of the ischium, internal to the origin of the semitendinosus. The fibres pass downwards, forwards, and inwards, to be inserted into the upper part of the condyloid pit of the femur. Gastrocnemius—an enormously large fleshy mass, investing the back, front, and sides of the leg—arises by four heads: one from the external side of the patella and ligamentum patelle, as far down as the tubercle of the tibia; the second springs from the external condyle of the femur and external lateral ligament; a tendinous pulley passes across from the upper part of the outer condyle, looping round to the external head, and around this winds the biceps; the third head is attached to the deep pit over the internal condyle; and the fourth, or external or largest head, arises from the anterior and lateral aspects of the tubercle of the tibia, the ligamentum patelle, and both patelle, also from the fibula by fascia, for its whole length. All these masses unite, and end in a large flat strong tendon, nearly two inches wide, which is inserted into the edges of the metatarsal bone as far down as its lower third; this tendon winds over the trochlear surface at the end of the tibia, forming a sheath for the deeper tendons on the back of the metatarsus. Tibialis anticus—long and thick—arises by two heads: one internal fleshy, from the outer surface of the groove on the outside of the tubercle of the tibia; the outer by a very strong round tendon from the articular surface of the outer condyle; this soon becomes fleshy, three inches below its origin, and unites with the former. The tendon passes to the ankle under a distinct annular hgament, and splits into two parts for the pas- sage of the extensor ungualis, each part being inserted into the lateral ridges on the anterior aspect of the metatarsal bone. The deep origin of this muscle is sheathed by the synovial membrane of the knee joint, which it strengthens very considerably. The anterior tibial vessels and nerves pass through the same sheath of the annular ligament, and the anterior tibial nerve passes through the splitting of the tendon. Extensor digitorum communis arises fleshy from the sharp ridge of the anterior aspect of the tibia to five inches below the tubercle, and — from the bony surface external to it; the fibres run to a strong round tendon, which passes in front of the ankle, internal to the last, and separated from it by a strong second annular ligament which binds it down; the tendon passes downwards, and ends in a flat expansion, which, at the metatarso-phalangeal joint, sends a slip into the proximal ex- tremity of each of the phalanges. Extensor unguis—a very delicate muscle—commences by a thin round tendon at the front of the trochlea, at the lower extremity of the tibia, close to the internal malleolus ; this tendon passes through the insertion 21 of the tibialis anticus, and ends in an extremely fine muscle, lying in a groove in front of the tibia; this belly ends in a tendon seventeen inches long, which passes under the extensor of the outer toe along the tendon of the last named, to be inserted into the last phalanx of the inner toe. The action of extension or elevation of the last phalanx and nail is facili- tated by the prolongation upwards of the synovial membrane on the dor- sum of the third phalanx. Flexor digiti interni, arises by two heads—one from the outside of the tubercle of the tibia, the other from the external lateral ligament of the knee, separated from each other by the rectus tendon; these unite, and end in a tendon which passes in a groove in the sheath behind the tibio-metatarsal joint, and is inserted by two slips into the base of the third phalanx of the inner toe; the deep flexor perforates its last por- tion, and the superficial flexor is perforated by it; a sesamoid bone ex- ists in the back of the metatarso-phalangeal joint, to which the retinacula are attached. Flexor digitum magnus begins also by two heads—the upper, fleshy, from a deep pit above the condyles of the femur, in common with several other muscles; the lower from the tendon of ie rectus, and external lateral ligament, and from the back of the fibula; these heads unite to form two fleshy bellies, detached above, but united below and behind the ankle by the junction of their tendons, which pass in the sheath behind the jomt, and here the united tendons are perforated by the flexor externi digiti tendon. In passing down to the foot, the flexor digi- torum tendon receives a slip from that of the gastrocnemius, at the me- tatarso-phalangeal joint, and sends a slip into the sesamoid tubercle of the former tendon; the tendon forms a sheath on the plantar surface of the toe, and is inserted into the base of the second phalanx by two slips. Spee profundus digitorum is the deepest tendon in the foot; it commences by two distinct fleshy masses—one from the pit in the back of the condyle of the femur, and the other from the posterior aspect of the tibia for its upper two-thirds; the tendons of the two are separate as far as near the metatarso-phalangeal joint, where they unite, and are inserted into the last phalanx of the great toe, and by a fine slip into the last phalanx of the outer toe. Flexor perforatus externi digiti arises by two heads—one from the pitin the back ofthe femur by a common muscular origin; and the second from the external lateral ligament of the knee; the tendon passes down the com- mon groove behind the metatarso-phalangeal joint, where it ends by three slips—one into the proximal phalanx of the lower toe; the two others are separated by the slip of the fiexor profundus; and the outer is inserted into the base of the second phalanx, im common with the fore- mentioned extensor slip of the little toe; the third passes to the base of _ the third phalanx. Interosseus—an extremely delicate muscle—arises from the whole length of the interosseus groove, the two heads being separated at their origin by the interosseus artery piercing the bone; the tendon is flat 22 and ribbonlike, and passes over the spur on the outer condyle of the metatarsus, and is inserted into the outer side of the base of the first phalanx of the outer toe; a few oblique fibres on the opposite side of the bone represent the dorsal interosseus muscle. Popliteus—a small, triangular muscle, having the base at the tibia, and the apex upwards and outwards—arises tendinous from the head of the fibula; the fibres pass downwards and inwards, to be inserted into the upper part of the tibia, as far as the internal lateral ligament. The popliteeal vein separates it from the back of the fibula, and the artery and nerve lie superficial. The articulations of the lower extremity present many points of mechanical importance. The first, or the hip, is an enarthrosis, sur- rounded by a capsule, loose, expanding inferiorly ; the synovial mem- brane spreads over the great trochanter; a strong transverse band passes from the border of the lesser sciatic notch to the upper and posterior edge of the acetabulum, under which the articular vessels pass to the joint. An extremely strong ligamentum teres passes downwards, out- wards, and forwards, from the lower border of the cotyloid cavity, and is inserted into the upper part of a depression on the head of the femur, near which it is cylindrical ; at its origin it is flattish and expanded ; a cotyloid ligament protects the superior and anterior edge of the joint ; thick and cartilaginous above, thin and membranous below and in front. The bottom of the cavity is separated from the air cells by a membrane consisting of fibres running downwards and forwards, and some radiating. The knee is a ginglymus, formed by the femur, patella, tibia, and fibula. The ligaments are: internal lateral, coffin-shaped, from the inner condyle, running downwards and backwards to the inner side of the popliteus. ‘The most posterior fibres arise entirely from the internal semilunar cartilage, which they assist in fixing. The patella is large, flattish, made of two parts, the external surface larger, the inner smaller and more cartilaginous; the quadriceps is inserted into its upper border, and from its lower edge passes off on its inner side a large flat ligament, whose fibres, stretched over the Haversian masses of fat, converge, to be inserted into the upper edge of the tibia on the inner edge of the tubercle. From the lower border of the true patella to the upper surface of the tubercle of the tibia extends a long, prismatic, bony column, united above to the patella by strong fibres, and resting below on the tubercle, with which it articulates by a strong ligament and a small synovial membrane. This seems to be properly an ossified ligamentum patelle rather than a true second patella. On the outer side. of the joint there is a superficial hgament, which forms an origin for the long flexor muscles, and is attached above to the front of the outer condyle of the femur, and below is united to the origin of the before-named muscles. Some parts of it are inserted into the semilunar cartilage, and others pass downward, and slightly backward, 23 to be inserted into a ridge on the side of the fibula. Beneath this a deeper ligament runs from the posterior portion of the outer condyle, downwards and backwards, to the anterior aspect of the head of the fibula; and the most anterior fibres are attached to the external semi- lunar cartilage. A synovial ligament, composed of synovial membrane, and containing a few blood-vessels, runs from the Haversian mass of fat to the front of the intercondyloid notch of the femur. Alar ligaments are two thin folds of the same structure, which lie on either side of the patella, and are inserted into the upper part of the middle ridge on that bone. Their free borders are directed inwards, towards the mesial line of the jot. The outer is much less distinct than the inner. ‘The an- terior crucial ligament arises from the inner side of the outer condyle, far back. It passes downwards, forwards, and inwards; and is inserted by two slips into the anterior cornu of the internal semilunar cartilage, and into the inner and anterior border of the internal condyle of the tibia. The posterior crucial runs from the posterior and superior part of the deep pit between the condyles of the femur, downwards and for- wards, to be inserted into the spine of the tibia on the outer side of the posterior cornu of the internal semicircular cartilage, sending a small slip into the inner edge of the outer cartilage. There are two of these latter bodies—one semilunar, internal, with a thick outer rim, attached by its anterior cornu to the head of the tibia and transverse ligament, and by its posterior to the back of the spine of the tibia, and by a strong slip that passes behind the posterior crucial into the inner surface of the outer condyle of the femur. The external is larger, and forms a com- plete deep cup for the outer condyle. Its lower surface is irregular, to suit the upper part of the tibia and fibula, especially in front; it is con- nected to the internal by a broad and flat transverse ligament in front of the anterior crucial, and behind the Haversian mass of fat. Beneath the transverse ligament lies another broad flat band, from the front of the internal condyle of the tibia to the lower surface of the external semilunar cartilage. ‘This body is connected to the anterior edge of the fibula by two small flat bands, one above the other, the lower being the larger, and both running backwards and outwards; behind, it is con- nected to the posterior edge of the head of the fibula by a small trans- verse slip. The superior tibio-peronzeal ligament passes from the outer and an- terior part of the head of the tibia to the inner aspect of the head of the fibula, underneath the outer semilunar cartilage. An inferior ligament unites these bones below. The chief agent in the joint to limit rotation consists of the strong tendon of the long extensors, which, arising from the external condyle of the femur, passes along the outer side of the tibial tubercle through the joint, enclosed in a fold of synovial membrane. ‘The origin of the flexors externally likewise is a strong protective to the articulation. If the jomt be suspended, it naturally rotates outwards. ‘The anterior erucial is far stronger than the posterior. The strong prismatic ossified | ligamentum patelle anteriorly limits flexion forwards. This is con- _ 24 nected above to the true patella, is about two inches and a half long, and below is articulated with the upper surface of the tubercle of the tibia, a synovial sac intervening between the two bones. The Haversian gland is large, and contains cells of fluid fat. The tibio-metatarsal jot is also ginglymoid in structure, and the two bones are united by the following ligaments :— Internal lateral arises from the upper and back part of the promi- nence on the inner side of the lower end of the tibia. It passes down- wards and forwards, to be inserted into the internal lateral ridge on the metatarsus for about four inches. The deep internal lateral is anterior to the last, and passes from the deep pit on the inner side of the tibia, downwards and forwards, to the ner edge of the front of the meta- tarsus. This ligament is twisted in the extended position, and straight- ened as the limb becomes flexed. As this band slips over a prominent ridge on the edge of the inner side of the tibia, it gives a spring to the joint. The superficial external lateral ligament runs from the upper and anterior part of the outer side of the tibia, downwards and backwards, expanding, to be inserted into the posterior part of the outer edge of the metatarsus. The deep external lateral hgament arises in a deep pit on the outer side of the external malleolus, an inch below the last. It passes downwards and forwards, expanding, to be attached to the an- terior part of the metatarsus. A distinct posterior ligament exists, covered by the great tendons lying in their sheath, which is attached to the upper border of the metatarsus by strong fibrous slips. In front, a convex fibrocartilaginous anterior ligament covers the joint, running from the tibia to the metatarsus, fibrous on either side, and cartilaginous in the centre, where it sends septa in between the various tendons. Posteriorly and externally a rhomboidal inter-articular cartilage is observable, which is retained in its place by two bands—one anterior, passing forwards, semilunar in shape, and attached to the front of the metatarsus; another running backwards, shorter, and attached to the posterior part of the notch between the condyles of the bone. This acts in preventing over-extension of the jomt, and in increasing its elas- ticity. Respecting the osseous anatomy of the ostrich there are no novel points of importance observable in either of our specimens. In the pelvic arch the principal characteristic seems to be the prolongation into lines of those parts which in most other animals are represented by points, as is exemplified in the posterior inferior iliac spine, which is described in the Appendix to ‘“‘'Todd’s Cyclopedia” as a separate sacro- iliac element; also in the elongation of the rami of the ischium and pubis. The lesser sciatic notch is also closed below and behind by a bony connecting band between the ischiatic spine and tuberosity, so as to be converted into a foramen through which the obturator tendon winds. 25 G. C. Garnett, M. A., read the following paper on Ancient Galleys ; and presented a collection of drawings and photographs to illustrate his paper :— On Ancrent GALLEYS. Tue subject of ancient Galleys, which I have the honour to bring before your notice this evening, is a theme, I believe, which has often engaged the attention of many learned societies, both in our own country andin those parts of the Continent which are most notable to us for their anti- quarian and literary researches. Indeed, to trace the subject from the infancy of naval art would, I believe, be vain; for it is manifest that long before any detailed accounts were written, or at least before our preserved records, a system of naval architecture existed, which was far more complicated in its nature than either the hollow boats from trees (uovcEv\a) or rafts joined with leather thongs (axeécav). The first vessel of any importance we read of is the Argo, which we know had fifty oars, twenty-five on each side; and, taking a space of four feet as a medium distance between the rowers, we have a length of 100 feet; but in addition to this was the curvature of the bow and stern—a part of the vessel in which Trajan’s column exhibits no rowers or ports—and which curve would most probably be not less than seven feet, which would give a length of 114 feet, a size of vessel out of keep- ing with the mechanical arts of the period. In addition to this, we know that some were shaped sharp at both ends—in other words, the bow and stern were alike; whence they are called vies audirpupvor. Now, it seems highly probable that these vessels were used only for the purpose of river navigation, as their great length would be of inconvenience inturning. These, however, must not be confounded with the true naves longe, a much more recent inven- tion—vessels which had a true bow and stern. To Minerva, the happy mother of the arts and sciences, is ascribed the origin of the naval art; but at what period the idea first had birth is a question of much contro- versy. soe the Homeric poems seem a fit starting point for such an in- quiry; yet no source should be disregarded which can afford any infor- mation on the subject, and in the Archipelago many vessels are still seen bearing many of the characteristics described by Homer. It was after the Punic war, or 490 A. U. C., however, before the Romans can be said to have possessed any ships of magnitude. They were divided into two classes—merchantmen, ‘‘ é\«aées,” and “ vijes,”’ ships of war. These ‘‘ vijes’’ were, it is calculated, atleast eight times their breadth in length; they were at first ‘‘ uniremes,”’ but afterwards were ‘‘triremes”’— to a great extent, no doubt, a generic appellation to all vessels of war, just as we apply the term “‘liners” to vessels of 60, 78, 90, or 100 guns. The exact form of the original triremes seems doubtful. Those on the ‘‘Columna Rostrata” of Duilius are in a great measure, no doubt, offsprings of the sculptor’s imagination. M. Dupuis Delome, the R. I. A. PROC.—VOL. IX. E 26 ‘constructor of the ‘‘ French Imperial Marine’’ investigated this subject, in order to arrive at a correct model for the French Imperial Galley, lately built at Clichy. M. Jal, the celebrated naval authority, is of opinion that triremes were constructed principally with straight decks— an innovation, certainly, on the more generally received idea of the decks being considerably curved in form. The kinds of woods used were va- rious. The ‘‘ornus,”’ a kind of wild ash, and the ilex, or wild oak, were employed to a great extent; the fir was also used — ‘‘ Nascitur et casus abies visura marinos.” The Romans were most particular in the wood being dry and seasoned for the purpose. Oars were first used, and indeed used in almost all cases, in the “triremes,” sails being left for vessels of mercantile use. The ‘‘triremes’” possessed, indeed, according to Homer, a true deck; for you cannot allow a hatchway unless you have a deck— Nywy ixp’ exwxeTo pakpa BiBacOwv— and again, —eEls ix pla yn os eBawve IIpwpys Mr. Howell, indeed, holds these é«p/a vynos to have been the seats or benches upon which the rowers sat; but in my opinion they were merely the raised steps, or separate flights, seen in many models and drawings, and existing in the Trinity College model. These flights were invariably placed at the ends of the Galley, as we place the forecastle and quarter-deck. Indeed, Thucydides says they had no decks— 999 io A lat ’ ¥ ove’ av Ta TOla KaTaPpaKta €XoVTAsS. ‘‘ Neither had they as yet any covered nor decked ships,” which clearly shows the centre of the Galley to have been open. Indeed, unless this was granted, it is impossible to find out how the men that were rowing could have breathed, packed as they were in such numbers, the oar ports being so small as to afford no benefit in that way to them. The fitting of the ancient Galley which has changed least in form from its original design is the ‘“‘anchor.”’ It was first one-fluked, é7epo- zomos; but afterwards du@cBoros, or double-fluked, was used. In its original form it possessed no upper bar or arm, but merely a shaft and ring. But the most formidable of all the parts of the ancient triremes was undoubtedly the prow, or beak, which was generally of brass. We read, indeed, in the life of Themistocles, that when Ariamenes, ad- miral to Xerxes—a good man—attacked Themistocles, both ships, meet- ing stem to stem, and striking each other, their sharp stems, armed with brass, pierced, so indeed that they were fastened together, and could not be separated. And again, in the Life of Lucullus, we read that, in the Bay of Tenedos, Neoptolemus, the chief officer in command of the Galleys belonging to Mithridates, was attacked by Lucullus, who was on board a Galley of Rhodes, commanded by Demagoras, an expert seaman, whom © 27 when Neoptolemus saw he commanded the master to bear down upon him with all imaginable force; but Demagoras, fearing the beak and massive stem of the admiral’s Galley, refused to meet him ahead ; where- fore, tacking about, he received him astern, in which part, though in- deed the shock was very great, he suffered no damage. Now, this plainly shows that the curvature of the stern must have been at a considerable angle to the water, and that the stem or beak ran as if it were in and under the counter of the Galley. This hollow in the stern was left, no doubt, for the action of the rudder. The ancients seem to have had no limit to the size of these Galleys. The largest we read of was that of Ptolemy Philopator. This enormous - vessel was merely, it has been conjectured, built for show: she had 40 banks of oars ; she was 280 cubits in length, about 420 feet,—the length of the iron-plated frigates, Minotaur and Achilles. The subject of frequent dispute is, how these Galleys have been rowed or put in motion. M. Le Roy, in his ‘Sur la Marine des An- ciens” (Academie des Inscriptions), M. Jal, in his ‘‘ Archeologie Navale,”’ and others of a later period, have made investigations into this subject. One of the chief obstacles to the settlement of this question is the want of any accurate drawing or bronze existing by which the ¢nterior of the hull could be seen, with the arrangement of the seats. Few models, indeed, exist. There is one in the Museum of Trinity College, which I consider a most important model. It is a monocrota, or uni- reme; the boar’s head, the distinguishing feature of the Roman trieremes, points to its Roman origin. Its length is 9 feet 7 inches ; breadth, 3 feet 4 inches; and depth, 1 foot 5 nches—of which the underneath is a repre- sentation :— ——— ———— iii 7m °° p INNER SIDE OF LEFT FEMUR don into the patella; its weight is... 7402. tts plane of moment coincides very nearly with that of the vasti imternt, just described ; and it is almost impossible to avoid coming to the conclusion, that the peculiar elliptical cross section of the femur, and its longitudinal plane of maximum strength, are contrived with refe- rence to the strain of these muscles, so as to enable the slight and delicate structure of the OF OSTRICH, a, Insertion of ligamentum teres.

M. rectus femoris is not correctly described in any book that T have seen; and its true nature, and connexion with the muscles of the calf, were discovered by me quite accidentally. I had taken for granted, asa matter of course, that the rectus femoris terminated in the patella; but, as there were two patellas, I wished to know in which of them the muscle terminated: on dissection, to my surprise, I found that instead of ending in either patella, its tendon passed in a groove over and between them both, and, turning outwards and backwards into the calf of the leg, became provided with a second muscular belly, which formed one of the portions of the flexor digitorum magnus, the con- joined tendon of which passed under the heel, and terminated in the plantar surface of the toe. The rectus femoris, with its tendon, is therefore truly a digastric muscle, upwards of five feet in length (Fig. 9), and has its origin in the 54 anterior bony prominence of the ium, e, (Fig. 6), which is well marked on every pelvis of the Ostrich that I have seen. The tendon of this digastric muscle is united to that of the gastrocnemido-soleus, by a slip shown at a, Fig. 9 The weight of the fleshy belly of the rectus femoris proper is 7+ oz. 13. M. sartorius.—This impor tant and remarkable muscle arises from the anterior portion of the ilium, g, (Fig. 6), and from some of the spines of the lumbar vertebre ; and, passing in the usual manner across the inner aspect of the thigh, is inserted into the inner side of the liga- mentum patelle and into the top of the tibia; its weightis. . 180z. 14. MW. tacus—Has a lozenge-shaped origin on the anterior portion of the ilium, between the opponens quadrato femoris and gluteus minimus, d, (Fig. 6).

The blending of the fibres of pectineus with those of the vastus in- termus, a portion of which, like this muscle, terminates directly in the tibia, is not to be forgotten in considering the mechanical action of the muscles of the hip and knee joints. 18. LM. quadratus femoris has an origin on the ischial line, just below that of the MM. adductor magnus, and an insertion of a linear shape in the back of the sess Les of the femur, shown in Fig. 7; its weight is . 2207. 19. M. oponens quadrato femoris. —This muscle if have so named, because it is met with in many animals as the direct opponent of the ES ee ee ee Se “ D9 guadratus femoris. In the muscular system of the Ostrich and Lion this antagonism between the muscles 1s very striking. It is found oc- easionally in human subjects, and is described by Harrison under the name of MM. ilio-capsuiaris. While we had the Ostrich in the Dissecting Room of Trinity College, a human subject was brought in, which had the ilio-capsular muscle fully developed; and my attention was called to it by Dr. Bennett. I have occasionally found the ilio-capsular muscle in dissecting Monkeys. In the Ostrich, the JZ. opponens has an origin on the anterior sur- face of the ilium, between those of the Mm. sartorius, rectus, tliacus, and gluteus medius, as shown at f, (Fig.6); and is inserted in the anterior ridge at the base of the great trochanter, with the J. gluteus minimus (Fig. 7), with the fibres of which it is connected; it weighs. . . 12o0z. 20. M. obturator.—In the Ostrich, asin most nea. the eae ‘ond external obturator muscles are united, arising from both the inside and outside of the bony circumference of the obturator foramen, and from both sides of the obturator membrane; their common tendon passes through the ischiadic notch, n, (Fig. 6), which forms a pulley, changing the eon of the force through 90°, and receives, on emerging from the notch, the fibres of the little , gemell, placed at each side, anterior and posterior, to guide the obturator tendon to its insertion (Fig. 7) on the outer part of the top of the femur; it weighs . . .. . lig OZ. 21, 22.—Mm. gemelli weigh. ; + 02. 23.—M. coraco-cluvicularis.—In the wing of the Ostrich there is a very remarkable muscle, which arises from the bony margin of the co- raco-clavicular foramen ; this foramen corresponds in the upper extremity with the ischiado- pubic or obturator foramen of the lower extremity ; and the muscle, passing under a strap hgament on the shoulder to be inserted in the outer part of the great tuberosity of the humerus, cor- responds with the obturator muscle of the leg. I consider this muscle to be the second pectoral of ordinary birds, and to be the proper levator humert. It is usually placed between the first and third pectorals, on the sternum, and lifts the wing by means of a pulley, which changes its direction through 135°. This contrivance is necessary in birds of flight, in which it is of as much importance to stow the weight aft, as 1t is in ships to place the foremast well forward ; but, as the Ostrich is a running bird, the Divine Contriver has left the second pectoral to lift the humerus by a direct pull, without ex- pending any ingenuity on pulleys to change its direction, as is absolutely necessary in birds of powerful flight such as the Falcon, in which the pulley of the second pectoral is as remarkable a contrivance as the pul- ley of the obturator muscle in the Ostrich. In fact, throughout the whole range of the muscular mechanism of various animals, every pulley changing the direction of an original force presents a problem to be solved ; and tells us of a contriving mind, which has deviated, for some purpose discoverable by us, from the simple con- trivance of muscular fibres pulling directly from their origin to their in- sertion. 2) 56 24. M. gastrocnemido-soleus.—This great muscle has four distinct ‘heads— (a). From the outer side of the patella and of the ligamentum pa- tellee. (8). From the external condyle of the femur (Fig. 7.) (y). From the condyloid pit of the inner condyle, between the Adductor magnus and Hexor digitorum (Fig. 7). (6). From the tubercle of the tibia at both sides, and from the surface of the lower patella, and by means of fascia, to the upper part of the fibula. Altogether it weighs . . 1154 oz. This enormous mass of muscles repre- sents the gastrocnemius and soleus, inti- mately connected in their fleshy portion, but distinct both in origin and insertion. It is inserted, as shown in Fig. 10, by means of two powerful tendons into the upper and back part of the metatarsus, the tendon of the soleus being a little above that of the gastrocnemius. It may be regarded as acting from the circumference of a ring placed all round the knee joint, to the tendo Achillis; and its resultant pull is nearly in the axis of the leg. 95.

Any observer who examines the gait of the Ostrich, Emu, Cassiowary, or Rhea, in confinement, cannot fail to be struck with the ungainly effect produced on the appear- ance of the animal, when walking slowly, by the abrupt and odd- -looking lifting of the foot caused by the structure of the heel joint, giving an effect like that of string halt in 5 . g : .

Ihave been informed by eye- witnesses, that under such circumstances the Ostrich in South Africa almost touches the ground alternately on each side with its body, in every successive spring, and leaps with ease over rocks and shrubs of considerable dimensions that lie in its onward path. I have shown in the preceding part of this paper, that the force ex- pended in propelling the body of the ostrich forward is ten times the force employed in restoring the legs of the animal, preparatory to its next spring; more exactly, as 335°5 to 33°75. This enormous force acts upon bony supports, which are required by the necessities of a bird’s existence to be as delicate and light as possible; and it is, moreover, exerted almost instantaneously, so as to give the fullest effect to the bird’s spring. The question naturally arises, how is this force to be suddenly applied, without breaking | or dislocating the ani- mal’s legs ? The answer to this question is to be found in the peculiar structure soleus. EASON PO ENE AP RIE EE ) 61 of the rectus femoris muscle, which binds down the patelle, straps up the heel, and brings the whole machine into harmony at the moment that the spring is about to take place. The admirable mechanical economy of the leg of the ostrich may be illustrated by the parallel case of the Cornish pumping engine. Let us suppose a 100-inch cylinder engine about to commence its downward stroke, and to lift the pump rods, weighing many tons, by means of a force of steam which commences at a maximum, and is gradually let off by expansion to asafe and manageable quantity. It has been found by experience that 1t is necessary to cause a minute vibration of the beam ~ before letting on the full force of the steam—such vibration shaking all the nuts and pins into their proper positions before the great and sudden action of all the parts takes place; andif such a precaution were to be omitted, it is well known that the sudden impulse of the steam would break the engine. In the leg of the ostrich, the W/. rectus femoris supplies the place of the preliminary vibration; it acts before the extensor muscles come into full play ; it binds down the two patelle, braces up the heel joint, and gives the signal for the MZ. gastrocnemido-soleus and other associated muscles to contract, and thus produces what may be regarded as one of the most striking phenomena in nature, viz., that the delicate bones and ligaments of a bird’s leg, acted on by muscles equal to those influencing the hind leg of a horse, shall remain uninjured under the sudden action of forces, the slightest error in the application of which would break to pieces the machine on which they act. I can admire, though I do not envy, the reasoning powers of those Naturalists who believe that a mechanism such as this grew out of pre- existing forms without the interposition of an intelligent mind; and for myself I must declare, that I could as easily believe that the modern Cornish engine had developed itself from its clumsy predecessors by the way of Natural Law, and without the interposition of intelligent engi- neers, as that the leg of the Ostrich was produced by Natural Selection from the commonplace legs of its less perfect ancestors. 62 MONDAY, JUNE 13, 1864. The Very Rey. Cuartes Graves, D. D., President, in the Chair. G. C. GARNETT, M. A., read the following paper :— On ARMOUR-PLATED SuHIPs oF WAR. Tue first ships of war that were plated with iron were designed and constructed in America. Mr. Stephens, the designer and builder of some of the fleetest and most beautiful ships and steamers in the American marine, made, in 1845, a series of experiments at the expense of the American Government, to ascertain the resistance of iron plates to shot and shell. The result then arrived at was, that plates less than an inch in thickness would resist the impact of any shell then known ; and that a thickness of six inches of tron was impenetrable to every projectile that was brought against it, no matter how great the velocity, or how short the dis- tance at which vt was fired. These results were duly communicated to the learned societies in both London and Paris. Here indeed they fell, as Sir Howard Douglas observes, on stony ground. In France, how- ever, the result was different; for the powerful and energetic mind of the Emperor Napoleon was not long in perceiving the immense advantage of these results. Accordingly the French Government proposed, at the commencement of the Crimean war, that a class of vessels should be jointly constructed by the two governments: of these six were builtin France, and six in England. These were of the class known as floating batteries. Ours, indeed, were not ready until the Russian war was con- cluded, and have never seen service, if we except the “‘ Trusty,” against whose sides we are daily trying the force of spherical and conical pro- jectiles, and as yet without having obtained any settled result. They are, however, a class of vessels little suited for their intended purpose, being wall-sided, and presenting at both bow and stern a flat surface for shell and shot, but, as far as the English batteries are concerned, must for sea going purposes be deemed a failure. “La Gloire’ is built of wood, and is much stronger than is usual in our corvettes, or evén in our frigates, being built, as Scott Russell, Esq., F. R.8., observes, on the model of the French line of battle ships, ‘‘Algesiras” and ‘‘Napoleon,” each of 90 guns, whereas ‘‘La Gloire” only carries 40; her tonnage registers 3000 tons, and her actual displace- ment is 5000 or 6000 ; the dimensions are as follows :—Length, 250 feet; beam, 55; her maximum speed 1s 13°375 knots; and she is coated from three feet below the water line with 44inch good hammered iron. But perhaps the most curious circumstance connected with “‘ La Gloire’ is, that when she was building it was predicted that she would never be able to carry In a seaway her armour plating, much less her heavy ordnance. 63 Being constructed by Mons. Dupuis Délome, one of the most intelligent naval architects of the age, it seemed rather surprising indeed, to some, that he should have made so gross a miscalculation; and indeed experience verified their belief, for she was found to answer when at sea all that was required of her, even in the worst weather. Yet, as Mr. Russell observes, she must not be viewed as her builder’s ‘‘ chef d’ceuvre :”’ she was no doubt built to suit the capabilities of the French dockyards—an abundance of wood, and but littleiron. Had her build- ers possessed the resources of England, the probability 1s, her construc- tion would have been at least modified. The following is a true representation of this fine frigate, taken expressly for this paper, by Lieutenant Peile, R. N. R. —_—_—_—_—_SSS=S=_S——SE== == ———— ———— SS SSS —_ —_— SSSSSSSS= == = SS = ——_—_—_ SSS = — No doubt a great part of the stability depends on the materials of the hull being composed of the same or of different materials. In my opinion all iron is by far the most serviceable, yet I know that to this theory I have many opponents. General Sir Howard Douglas says, in support of iron bottoms :—“ In spite of their horror of iron, the Admi- - ¥alty ought to have discovered before this time that, even if the top sides of a man of war should be of wood, the bottom or water portion should be of iron; for it has been found in almost every case where one of our screw liners was driven at even the moderate speed of 1045 or 11 knots, the seams opened and the caulking escaped, and this indeed seems to be one of the strongest objections to converting old wooden vessels into demi-iron ships of war, such as the ‘RoyalOak.’”’ From a Parliamen- tary return, dated 4th of May, 1863, in reply to a motion of Sir James Elphinstone, it appears that there were built, and building, eleven iron and ten wooden iron-clad ships of war, and the seven floating batteries, of which three have never been commissioned ; and two, though sent on foreign service in a supposed efficient state, have cost the nation £3571 for repairs to the hulls, which expense indeed is not to be wondered at, when we find the ‘“‘ Thunderbolt,’ one of the batteries, has never been 64 commissioned, though launched on the 22nd of April, 1856, yet has cost no less a sum than £1291 for repairs to the hull. Vede Return to the Honorable House of Commons in reply to Sir James Elphinstone, dated May 5, 1863, No. 237. In reference to the cost of these iron-cased frigates, we find that in. the return made on the motion of Captain Jervis the total cost of the ‘¢ Black Prince’ was £373,899, of which the engines cost £74,449, the hull and rigging, £272,729, the balance being for alterations; while for adopting Griffith’s screw propeller a sum of £156 1s acknowledged. The “¢ Resistance’ and ‘‘ Defence’”’ have cost £257,848, and £252,898 ; while the ‘‘ Warrior’ even exceeded these charges, large though they seem, her total cost, according to these dockyard returns, being £377,373—a sum that in “‘ the days of old” would have been amply sufficient for two three- deckers and a 36 gun frigate.* Yet the question is not one of mere money: if the article contracted for was supplied, then there would be little cause for complaint, but in nine cases out of ten this is not the case. It isa matter of extreme difficulty to produce a ship of 400 feet in length with sufficient strength to stand heavy diagonal and transverse strains. Mr. Fairbairn, indeed, has investigated the relative strength of iron bars and plates ; and he shows that the cohesive power or strength of bar iron may fairly be taken at 25 tons, or 56,000 lbs. per square inch of section ; with bars of +inch each of Yorkshire, Derbyshire, Shropshire, and Staffordshire iron, he obtained a mean breaking weight across the fibre of 21:350 tons per square inch. The Shropshire plates were the best, breaking under a strain of 22°826, while the rest barely averaged 19°5638. The cost of all iron vessels is greatly increased by the corrosion, or rust, of the material; to counteract this fatal tendency various means have been employed. There are two materials or paints in use in the British navy—one known as Hayes’, and the otber as M‘Innes’, composition— their object being, in company with a number of others, to limit as far as possible the tendency to ‘‘oxidation.”” Monsieur Jean Pierre Jouvin, Pro- fessor of Chemistry to the French Navy, has patented an invention of a somewhat novel description. It consists of laying sheets of zinc against the ship’s sides, and between the hull and frame; and in case of the vessel being already built, coating the frame, and what portion of the hull can be reached, with a strong solution of zine paint. The zinc shects vary from zzinch to #5 inch thick, while the ribs, keelsons, clamps, transversal bulk- heads and all other parts not covered with these zinc.sheets, are coated with a powerful solution of the metallic zine paint. For the outside of * Mr. Bidder, one of our most eminent engineers, has pronounced the “‘ Warrior” in every respect a failure, save one—that she, under certain circumstances, is a fast vessel. Admiral Sir George Sartorius has also borne similar testimony—the vessel steering badly, and when she took a sheer, no action of the helm could stop her. She is also very lee- wardly, and rolled more than any line-of-battle ship. 59 the hull, however, this provision would hardly answer, therefore Mons. Jouvin coats it with composition composed of the following: Turbith mineral (SO;3HgO), mixed with Prussian blue (3Fe Cy + 2Fe? Cy°), producing by its contact with the “ alkaline chlorides’ of sea-water one of the most violent poisons known to mineral chemistry, viz., the cyanide of mercury (HyCy) in the shape of chloro-cyanide of mercury and sodium. He therefore first mixes 55 parts of turbith mineral and 45 parts Prussian blue, and composes the paint as follows :—Boiled linseed oil, 250 parts; red lead, 679 parts; and the aforesaid mixture, 100 parts; but this mixture must not be applied to the bare hull, which ~ on the contrary must first receive a coating of zinc paint of not less than 3 inch in thickness. I believe, of all the various compositions invented for the purpose, this of M. Jouvin to be the best. The metal Mr. Whitworth uses in the construction of his ordnance is known as homogeneous iron, very much of the same nature as mild steel. It is chiefly composed of bars of Swedish iron, cut into short lengths, melted in crucibles, and cast into a large cylindrical ingot, which is subsequently forged under a tilt hammer into the required form. The guns are forged solid, bored out in the usual manner, and rifled uniformly throughout their length, without leaving any chamber at the breech end. The pitch in the rifling of a 12 pounder is one turn in 60inches. Mr. Whitworth’s favourite projectile is a ‘ flat-headed’’* hexagonal bolt. To give an idea of its force, it may be stated, that when | it was fired at the “ Alfred” target ship at Portsmouth, the gun being laid at 450 yards, the shot passed through 30 feet of water diagonally, _ and eight inches of oak, piercing the timber three fect below the surface of the water ; when spherical shot, or long projectiles with rounded fronts, _ are fired in the water, they do not penetrate below the surface, but _ turn and come back again; the flat-fronted shot seems the best for _ traversing iron plates. If the round-fronted form of shot is fired against a thick wrought iron plate, it displaces the particles of the iron _ plate in a lateral direction, and has to overcome the great lateral resis- _ tance they offered to its passage. In the case of the flat-fronted shot _ the resistance is confined to the exact spot on which the flat front of | the shot strikes, the resistance then becomes direct, and not lateral; and if the ‘‘momentum”’ of the shot is sufficient, it displaces the particles of the iron plate, and forms a vacuum in the shape of around punched hole. With regard to the question of rifling the bores of guns, which seems to | be generally assumed as an indispensable theory in these days, there | are many opinions. Mr. Adams regards it as simply a contrivance for cor- recting the defects of badly constructed projectiles at a considerable waste of propelling power. If the centre of gravity of a conical shot is not placed at the junction of the major and minor axes, the resultant of * This kind of shot is said to have been used with great success by the captain of a | whaling ship, to kill seals, many years ago. R.A, PROC.—-VOL. IX. © K 66 the curve will be in a waved form. Andasit isa mere matter of chance where the dzas of a projectile may be in a gun, it is uncertain where the shot may fly to. The spinning motion in a great measure counteracts this; and with elongated shot, as commonly made, not only might the centre of gravity be out of the line of the central axis, but almost in- ~ variably, when made with its sides parallel, and with a conical point, it would, when placed in the gun, have the centre of gravity behind the middle of the length; therefore, on leaving the gun, it would try to turn over, to get the heavy end foremost, and it isin a great measure to coun- teract this that rifling is an advantage. One of the chief obstacles to high angle firing (in the case of conical shot), is the fact of the major axis of the cone always keeping a constant angle in all the points of its trajectory. In the diagram given below, it will be seen that both in the case of an angle of 85° and 15° the axis (major) remains parallel to its original elevation. This is of the utmost importance in ‘target practice;”’ for if the angle became, say 45°, the axes would become parallel to the face of the target. The impact would then become oblique, and the resistance of course greater in the ratio of the axis of the cone to the axes of the common round shot; this impact, in several of its properties, is but mdifferently known. The flame at the moment of concussion, now so generally observed, is the subject of great controversy. Is it the destruction of force? or is it the carbon evolved at impact by condensation of the molecules, which, mix- ing in the atmospheric oxygen, are fused by the heat generated by the concussion? It is true that the experiment of letting fall balls of iron from a great height into a well has had the effect of visibly raising the mercury in the thermometer; yet this heat is incapable of combustion, being at too low a temperature. Some think it to be the compression of the atmosphere to such a degree as to produce solidity, and im that state to evolve electrical properties. One thing remains certain, its ap- pearance in almost every case where steel shot, or shell, is fired against a resisting substance of iron. Would it not be possible to measure its intensity by means of a thermetrical index attached to the target? Pro- fessor Tyndall, F. R.8., has shown that heat generated by impact increases as the square of the velocity, so that the heat of impact in- creases in the same ratio as velocity is augmented. Now, the velocity REAM i OTS Ra WT a0 Ne ache eli Se ag AD Ss 67 imparted by gravity to a body falling through a space of 772 feet is 223 feet per second ; six times this, or 13838 feet per second, would not be an inordinate velocity for a rifle ball; but if this ball was composed of lead, this velocity would raise its temperature 30°; with six times this velocity, its temperature would increase about 36 times, or 1080°, with a velocity 1338 feet per second, quite sufficient to fuse the lead if con- centrated in the ballitself; but the fact is, itis divided between the target and the projectile, and in the case of the iron projectiles only one-fourth of this amount, or 320°, would represent the heat. Mr. Joule, of Manches- - ter, has shown that if indeed all this heat in the target, after concussion, and in the projectile, and latent in the gun itself, were combined, the force represented would be sufficient to propel it back along the pro- jected trajectory into the gun again. The concussion produced by these heavy pieces of ordnance is very great; and the lateral and longitudi- nal strains on the timber of the ship, such as to render the stability of the vessel a fact of the greatest importance: the vertical line being in a state of fluctuation produces an immersion, and consequent emersion, greater or less according to the stability of the vessel. Mr. Peake has shown that the height of the metacentre above the centre of gravity of displacement of the immersed portion of the body may be represented by the following formule* :— GE _ , 2(y?xsin Ox dz 1 (yx dx from which we deduce 2 (y3 dx oi) Ds a formula of great practical benefit in calculating the relative stability of floating bodies. Baron Sané and M. Tupinier used the following formule for the relative values of the contents of the parallelepipeds of his famous 18-pounder frigates and ‘“‘ La Guerriére,” an old 36-gun French fri- gate :—in ‘‘ La Guerriére,”’ * This determines the height of the metacentric point (m) above the centre of gravity (G) of the displacement. and finding means for x. y.2.

On the 11th of December, 1863, Sir William Armstrong’s “ Big Will” was fired at Shoeburyness, and with what results will be seen. This piece of ordnance weighs 224 tons. Itis what is technically termed a built gun, being composed of eight coils of metal. “It is rifled with ten grooves on the shunt principle, and the shot is made to rotate by means of ten rows of gun metal fitting into these grooves; each row contains five stems, and these stems, being made of softer metal than the grooves, do not injure it; the gun is fifteen feet in length, and the internal diameter is 135%, inches, and the external diameter at the muzzle one foot nine inches. At ten degrees elevation, the range is no less than 4000 yards. The average weight of the shot is 600 lbs., and eae 69 these are divided into three kinds—the first solid, 510 lbs.; the second hollow, for a bursting charge; and the third, a segment weighing 600 lbs. This is composed of a thin case, similar in form to that of a common shell; inside this case is built up a series of loose pieces of iron, so con- structed as to form a series of rings from bottom to top; these seg- ments number 510 pieces, each weighing six ounces; a time fuze is set on the top of the shell, which communicates with the bursting charge, fifteen pounds of powder inside the shell. After ‘‘ Big Bill’s” trial against the. ‘‘ Warrior target,’ the target itself underwent a strict scrutiny. The target was found fractured in every direction in radia- tions from the oblong aperture or rent, which was two feet long, and one foot eight inches wide in front, a couple of inches from the circular white sight, as shown in the accompanying engraving. The three- fourth inch iron backing was found torn away in long slips: the sight, indeed, when the target was struck by the shell, is said to have been very grand. The shell is said, from its enormous size, to have been dis- tinctly seen during its entire flight of 1000 yards; and at the moment of impact volumes of smoke burst from the target, accompanied with sheets of flame. EXPERIMENTS WITH THE ‘‘ Warrior” Tarcet.—The experiments at Shoeburyness have done much to elicit the respective merits of the various guns, and the different constructions of targets. In these trials, the breech-loader was withdrawn by Sir W. Armstrong. Ex- cellent, no doubt, as a shell gun against wood, it does not possess that penetrating power to become a formidable antagonist against armour- plating. Originally intended to be fired with-14lbs. powder, this charge was further reduced to 12 lbs., and again reduced to 10 lbs., which is about what the weight of the gun, 60 cwt., isable to bear. The weight, and bore, and charge of the two competing 70-pounder guns were as follows :— 70 TABLE a. Description of Gun. Bore. Weight. Charge.

The Marquis of Hartington, Under Secretary of War, has stated in the House of Commons that the Armstrong 600-pounder is the best gun the country has as yet got from any inventor, which has been proved by the wonderful accuracy of range and great power exhibited by this gun. Undoubtedly it is the best of a// the Armstrong guns, their principal faults arising In a great measure from the fact of their being breech- loaders—a species of gun not to be depended on with any degree of confidence. Whether, indeed, such a gun as the 600-pounder could be used on board the ‘‘ Royal Sovereign’”’ or ‘‘ Warrior” is doubtful, the ship roll- ing at an angle, say of 17°, would render the weight on the vertical line of oscillation so great as to strain the ship, and affect her stability in a most dangerous degree. In such a case forts would possess a manifest advantage over ships if armed with such guns; while if seaports pos- sessed flat-bottomed barges, propelled by a screw, carrymmg even one 600-pounder, any part of the coast could be easily reached, and rendered secure against an enemy, from the extreme range and power of the gun. 73 TABLE 6.

L » A. PROC.—-VOL. IX. 74 Ihave been informed by an officer of the Royal Horse Artillery that _ at 24° the range of the Armstrong 9-pounder with 1 lb. 2 ozs. powder (charge) has a mean velocity of 955 feet per second. The above are some of the results of the experiments made with the Armstrong and Whitworth guns, by J. A. Longridge, Esq., C.E. In all these cases the actual range is far below the range im vacuo, or the parabolic range. Mr. Whitworth’s shell is well known to have high penetrating power. A series of experiments are detailed in Sir James Emerson Tennent’s ‘‘Story of the Guns.’ Its possessing no fuse has, indeed, been deemed a novelty; yet so far back as 1848 the French frigate ‘‘ Psyche” possessed sheils of a similar nature, invented by Capt. Bil- lette, of the French navy. They were fired from the ordinary service guns of a large calibre (84-pounder). It is said to have been used with disastrous effect by the French at Mogador, in 1844, and subsequently at Algiers. If let fall from the upper to the lower deck, no accident is said to have resulted. Its combustion was, it is said, caused by the heat generated in its passage through the atmosphere, after attaining a given velocity. The following is a table of comparison between the Whit- worsh and Armstrong 12-pounder :— TABLE Z. Description of Gun.* Elevation. | nee: Pen peceren, ae | | hE | Deg.

Krupp, of Essen, in Rhenish Prussia, has been designed. Mr. Whitworth’s large 80 cwt. gun, with a charge of 123 |bs., obtained an initial velocity of 1313 feet per second with a projectile weighing 80 lbs., and obtaining a range of 4400 yards. What we want for all our guns is comparative lightness * Vide “ Proceedings of the Institute of Civil Enginecrs,” vol. xix., p. 442. ed z : eee 79 and durability, combined with a2 moderate amount of wear. That the breech-loaders are most properly abandoned is now an admitted fact. The cost of the old 8-inch cast iron guns was about £100, while the cost of a similar breech-loader is about £800, while the initial velocity has been proved by H. M.S. ‘‘ Excellent’s” practice to be very inferior to that of the muzzle-loaders. The mean velocity of a 491b. shell, fired from a 32-pounder rifled service gun was shown to be 1120 feet per second, with a range of 1600 yards, while 826 feet per second is the mean initial velocity of a breech-loading field service gun. Guns, it must be admitted on all sides, will have an advantage over ships, as there is 20 absolute restriction to the size of the gun, though there 1s to the size and weight of the armour-plates of the ships. That great desideratum—“ stability’’—seriously affects all our iron-clads, and is a fault that can only be rectified by the loss of a great portion of that armour plate that renders them ‘‘ invulnerable’’ (?). In the calculation of the effect of any explosive agent, due regard Mr. Longridge observes, must be given to the evolution of the perma- nent gases. Captain Boxer, R. A., in his valuable treatise on Artillery, computes the gases evolved from one cubic foot of gunpowder when re- duced to ordinary temperature to be WNatrogens Vi. tn (9-4 cubic feet, Carbonic acid, . . « 2388°0 ‘ er, according to Mariotte’s law, a pressure of 317°4 atmospheres. This pressure may indeed be estimated by this law, represented by the equa- tion to an adiabatic curve— 1 \ i 1 p [v Here p and y’ are the pressures before and after compression; v and v’, the volumes corresponding ; 4, the ratio of the specific heat at constant volume to that at constant pressure. In the case of air, /=1°41; and if this be the same for carbonic acid and nitrogen, the pressure "after compression = 317°4 atmospheres, = 3367 . = 22°17 tons per square inch. In estimating the initial force of gunpowder from the velocity as ascer- tained by the ballistic pendulum, the usual method is that of Dr. Hutton, to find the value of » in the formula :— / nh a? b =r prw Oe, from which we obtain | n=(p+w)v b 47-4Phd? Log - 16 Now, Dr. Hutton obtained from this formula the value of () = 2-400 atmospheres, or 15$ tons per square inch. The result, as Mr, Longridge observes, 1s far from accurate: as the variation of pressure must be allowed for Mariotte’s law, by adopting the true thermo-dynamical law, we have (pt w)v a Coe eek Dy Me? AT: 47-4 \2q2 Gai a = or, applying it to Mr. Whitworth’s 80-pounder, with a velocity of 1300 feet per second, a pressure of 24:58 tons per square inch.

The greatest speed yet obtained has been that of the ‘‘ Achilles ;”’ this vessel obtained a speed at full boiler power of sixteen knots. The ‘‘ Warrior’ obtained a speed of 134 knots at a mean draught of 264 feet, completing her circle in eight minutes and thirty seconds, while the ‘‘ Mersey” took forty minutes ; one of our crack 3000 ton frigates took no less than eleven minutes and fifteen seconds to do the same. The length of the ‘‘ Mersey” is 287 feet 153% inches, and that of the ‘‘ Warrior’’ 383 feet 22 inches, which makes ie se War- rior’s’’ superiority the more remarkable, and proves that a long ship can answer the wheel as well as a short one ; but in stability little can be said for vessels of the ‘‘ Warrior’ class. ‘The index pendulum on the ie wheel standard gave a registered immersion and emersion of 15° star- board, and 12° port; and there is little doubt but that in a gale of wind the deflection will be considerably more, as when the above deflections were registered the weather was moderate. No doubt exists of the want of stability in vessels of the ‘‘ Royal Sovereign” class,when the weight of the turrets is considered—130 tons, and the 54 inch armour plate. The plan adopted, also, of transforming old wooden liners into iron cupola ships, is evidently erroneous,—the timbers of these ships not be- ing able to withstand the strain of the increased weights; their ponder- ous turrets also are most objectionable,—liable, on the one hand, to get out of order, from failure or injury of the revolving machinery; and, on the other, to become rapidly choked with smoke. They oxidize to a great extent, and once strained out of the vertical line are incapable of rotation. In order to substantiate the above theories we have many American testimonies. I cannot but state a few of the most remarka- ble here, quoted from authentic sources. The official reports of the commanders of the Monitors, or turret-ships, made immediately after the failure of the attack upon Fort Sumter in April, 1863, tend to show that these vessels are incapable of resisting the concentrated fire of heavy rified ordnance. Capt. Drayton, of the ‘“‘ Pas- sive,’ says:—‘‘The ship was struck in quick succession in the lower part of the turret by two heavy shots, which bulged in its platesand beams, and, forcing together the rails on which the carriage of the 11-inch gun revolved, rendered it wholly useless for the remainder of the action. A little after a very heavy rifled shot struck the upper edge of the turret, broke all its eleven plates, and then, glancing upwards, struck the pilot house with such force as to send it over, open the plates, and squeeze out the top, exposing the inside of the pilot house, and render- ing it useless.’ Capt. Rogers, of the turret-ship ‘‘ Weehawken,” says :— ‘““'wo or three heavy shots struck the side armour near the same place; they so broke the iron that it only remained in splintered fragments, much of which could be picked off by the hand, and the wood exposed ; the iron was five inches thick. The ‘ Petapsco’ was disabled, and the ‘Nantuck’ and the ‘ Nahant’ had the iron stripped from the wood, their sides bulged in many places, and several holes in the turrets. Their armour plates on the cupolas were disconnected, and the rivets broken ; and before the close of the action the ‘Weehawken’ had shot- holes in her sides so low down, that the water ran into the ship in streams.’ Such is the published American account of their iron-clad cupolas in action, and it can hardly be hoped that our turret ships are by any means capable of performing with more satisfactory results. There seems every probability that gun-cotton will in a great mea- sure take the place of gunpowder in iron-cased ships. In Austria it has already done so. It has, no doubt, disadvantages, yet from recent ex- periments it would seem that these were counterbalanced by certain properties of most beneficial tendency. Xyloidine, first discovered by M. Braconnot, bears a certain affinity to the pyroxyloidine of Professor Scheenbein ; yet the former is essentially different in its composition, and 18 has been proved to be unsuitable for firearms. John Hall Gladstone, Esq., of University College, London, has shown that by combustion with oxide of copper in a stream of oxygen, the following results were obtained :— * Grains.

This composition exploded at a temperature of 370°, producing no smoke, and leaving no residue. Acetic acid at once de- stroys its fibre ; chloroform apparently does so to a certain degree ; yet, if the collodion formed is viewed microscopically, the disentegrated fibre will be seen to reunite atomically, a fact first mentioned to me by Dr. Carte, Curator of the Museum, Royal Dublin Society. Professor Barker has also informed me that he found it to explode, over a hot water bath, at 212°.* The formula C., oe \ O. gives carbon 26°23; 4 hydrogen, 2°73; nitrogen, 12°75; oxygen, 58:29.

The Rev. Joun H. Jexzertr, A. M., Vice-President, in the Chair. Sir Wittram WILpg, read a paper On tHE ANTIQUITIES AND Human REMAINS FOUND IN THE CouNnTY oF Down, rn 1780, AND DESCRIBED BY THE CountTEss oF Morra IN THE “‘ ARCH HOLOGIA,’? VOL. VII. In the autumn of 1780, the body of a female, clothed in antique woollen costume, was discovered in a bog, at the eastern foot of Drumkeragh Mountain, in the barony of Kinalearty, and county of Down, the cir- - cumstances attending which, as well as the character of the costume, : | : | | | ' have been described by the distinguished Countess of Moira, in a letter, ' forwarded to the Society of Antiquaries in London, in 1783. That com- 102 munication has been long known to Irish antiquarians, and appreciated for its learning and patriotism; and I myself and others have often re- gretted that that remarkable discovery had not taken place in our own times, so that an opportunity might have been afforded us of examining the costume, or procuring it for the Museum of the Academy. Owing, however, to the liberality of one of our members, the Earl of Granard, the great-grandson* of the original describer of these remains, I am now enabled to present to the Museum of the Academy the great bulk of the articles which came into the possession of Lady Moira nearly eighty-four years ago. From an examination of some of these speci- mens, it is manifest that a series of ‘‘ Warp lifts,”’ supposed to be a com- paratively modern invention, was in use in Ireland when these articles were manufactured. In the memoir in the “ Archeologia” it is said that the human figure referred to was found buried in hard gravel, beneath 44 feet of bog, ‘‘and that upon and about the bones there were many garments.” It was also stated that the cireumstances under which the body was found showed evidences of burial; and also that the bog had been some years previously nearly eleven feet deep inthat spot. { have, however, been by long experience so accustomed to receive with great caution all accounts of such matters afforded by the peasantry, even where a shorter interval has existed between the discovery and the’recital than that re- corded by Lady Moira, that I think we must receive with caution details of that nature. The hair of the individual was long, silky, and of a deep chestnut colour; but how far this brownish-auburn tint is the original shade of the hair, or the result of the bog colouring, is questionable. Its present hue would be much coveted in our own day. The plait was formed of three strands, interwoven after the manner depicted in the adjoiming woodcut, and closely resembles the mode of wearing the hair in vogue among children and young girls a few years ago. The entire plait is now fourteen inches long. All the articles of costume described by Lady Moira were woollen—thus indicating that at the period to which they refer there was no linen or other vegetable fabric employed in that part of the country. What their origi- nal colours may have been it is now difficult to determine ; but at present they present several varieties of brown, from a dark orange, through the various shades of russet and sienna, to a colour almost black. More, however, may be gleaned from the texture, and manufacture, and pattern of the fabrics, than from the colour. All the seams and hems are made good with woollen thread of the same colour * Lady Elizabeth Hastings, Baroness Hastings and Hungerford, &c., in her own right, and Countess of Moira, was mother to Lady Selina Rawdon Hastings, Countess of Granard, from whom the present Earl inherited those portions of costume and hair referred to in the text.

In fineness, as well as quality and pattern, they vary exceedingly. Ten specimens have been preserved, and each differs from the other in colour, erist of thread, and arrangement in weaving. Some of them were evi- dently the chief garments of the person, and were intended for warmth and protection, while others appear to have been of a decorative cha- racter. The accompanying illustrations represent the most remarkable _ of these patterns.

They in- termingle, not as in a homogeneous piece of weaving, like modern cloth or linen, but having the warp standing in high relief, so as to present a corded surface, like that which is known in modern phraseology as “rep,” and which is not unlike coarse Egyptian linen. No. 3 is of a finer quality, but nearly of the same colour and close- ness. The pattern is what is termed herringbone, and the weaving superior in quality to the foregoing. The portion under consideration has been much patched, and a piece of the same manufacture forms a patch upon the long strip of the following.

Somewhat like No. 2, is a beautiful soft fragment, with a diaper twill, and of a light warm colour, partaking of a shade of orange. It probably formed a part of the cloak or mantle. Ofthe same colour, but of a light serge texture, there is a small fragment of woollen stuff still remaining; likewise some portion of cording, apparently used in tieing or confining the dress. The two remaining articles are of extreme interest. One of these, No. 5, is evidently a fragment of a light gauzy woollen veil, of the most delicate texture, and which it was believed by Lady Moira was of a greenish colour when first brought to light. The other, No. 6, is a piece of very closely woven hard firm thick mohair camlet of hair, not wool, and haying on its outer surface rows of ele- vations, from each knob of which depended a small black tab, so that originally the cloth must have presented an ermine appearance. The colour is now a reddish-brown, but the oj remains of the tabs are quite black. This may have been part of the tunic. Even ¢ during the present century ladies’ cloaks, tippets, and pellerines, and gentlemen’s dressing gowns, were ornamented with ermine-like appendages of this nature. The Rev. Samurn Haventon, M. D., F.R.8., Fellow of Trinity College, Dublin, read a paper— On an APPROXIMATE METHOD, FOUNDED ON OBSERVATION, OF DETERMIN- ING THE Datty Excretion oF UREA In HEALTH AND DISEASE. Tuer researches of chemists and physiologists, in recent times, have demonstrated that all the nitrogen received by the body in food is eli- minated by the kidneys; and that the supposition that the skin or lungs contribute, except in very small proportions, to this elimination, is erro- neous. ‘This important fact, based upon very accurate experiments, would seem to render more necessary than it is considered usually to be the determination of the amount of Urea excreted in health and dis- ease. To find the Urea in a given liquid, requires a combination of qua- lities and circumstances that can only rarely occur to the practical physician. 1. He must be a good chemist. 2. He must have a chemical laboratory at his disposal. 3. He must have thirty-five minutes to spare on each case in which he determines the Urea by Liebig’s nitrate of mercury process. = ee Ck ah Saeed We Ee Wie a 105 These conditions, the coexistence of which in practice is impossible, have prevented practising physicians in modern times from paying that minute attention to the urine of their patients that was customary in the éarliest times of medicine. __ Inthe accompanying Table, which is founded on many observations of urine, both of health and disease, of specific gravities from 1003 to 1028, I have given what I believe will prove a very useful approximation to the daily excretion of Urea in all cases in which sugar is absent, and albumin either absent, or only present in small quantities. The Table is one of double entry, to be used in finding the daily excretions of urine in fluid ounces, and its specific gravity determined by a carefully graduated urinometer. T submit it with confidence to the test of practical experience, as I have so often tested it myself in fever, in pneumonia, in dyspepsia, and in kidney diseases, that I believe it will be found a most valuable aid to the physician, both in the prognosis and in the treatment of these and other diseases.

Habitat.—This highly interesting addition to the British and Irish Floras was discovered, in May, 1864, growing on the dry calcareous pastures of Castle Taylor, county of Galway, by Miss More. OzsERVATIONS.— When Dr. Lindley described and figured this plant in the ‘‘ Botanical Register,’ he remarked that it had an unusually extensive geographical range for an Orchis; the present discovery, how- _ ever, extends the range very considerably, and is highly interesting, | geographically, when viewed in connexion with some other plants _ which occur in the neighbouring counties of Kerry and Mayo. In those | counties it is well known that several plants which are typical of the | south of Europe Flora, and also of the Flora of North America, appear, R. I, A. PROC.—VOL. IX. 1g 106 though not found elsewhere in the British Isles: they seem to form the solitary outlying posts of the geographical distribution of the plants belonging to those Floras. In Cork, the pretty Orchid, Neottva gemmipara (Smith) grows, which at one time was considered to be confined to Ireland, but has since been found to be a North American species. Again, in the county of Galway, the pretty aquatic plant, Navas flexilis, another plant of the North American Flora, occurs. In Kerry several of the Saxifrage of the Pyrenees appear, and several of the Pyrenean Hricaceous plants extend from Kerry, through Galway, to Mayo; but stop there, and are not found further to the east, south, or north of this island.

This result differs from that formerly found for Dublin, where the maximum and minimum of Evaporation coincide very nearly with the times of the sol- stices themselves. This difference is produced by causes not difficult of detection. 148 MONDAY, NOVEMBER 14, 1864. The Very Rey. Cuarztes Graves, D. D., President, in the Chair. Grorcr V. Du Noyer, M.R.I.A., R.G.8.1., presented to the Li- brary of the Royal Irish Academy, 99 Drawings from Original Sketches of Antiquities, in the counties of Westmeath, Longford, Meath, and King’s County, to form Vol. VI. of similar donations ; of these the fol- lowing is the Catalogue :— No. 1. Doorway of the church erected by St. Fechin at Fore, county of Westmeath ; interior view. St. Fechin died A. D. 664. No. 2. East window in the chancel of St. Fechin’s church at Fore, showing thirteenth and probably sixteenth century work. No. 8. Plan of the same church, showing the modern chancel, the date of which may be the thirteenth century, though modified in the sixteenth century, as is evident from the reconstruction of the east window. No. 4. Proposed main doorway to the chapel of the Abbey of Fore. Sie Jt would appear that this doorway, which is constructed in the west wall of a massive square tower placed at the west end of the chancel, was never completed, probably owing to some change of design in the construction of the abbey. There is no trace of its exterior semicircular arch in the interior portion of the doorway, while the simple roll- moulding which surrounds the doorway is left unfinished in the arch. The form of the doorway and that of the moulding is clearly of the thir- teenth century. No. 5. Capitals of cloister columns from the abbey at Fore. The style of the mouldings and the presence of a slender rib in the lower © | hollowed portion of the capital are all characteristic of the early English style, or that prevalent in the thirteenth century. No. 6. Intercolumnation of some of the cloister arches from the ab- | bey at Fore. No. 7. View of the west gate of Fore, looking eastward. No. 8. View of the same from the opposite direction. No. 9. View of the east gate at Fore. No. 10. Old font, built into the exterior of the wall of the Roman — | Catholic chapel at Fore. Fore. No. 12. Heraldic carving from a stone which appears to have formed | the springing of one of the cloister arches at Fore Abbey ; but now used as | a headstone in the graveyard of St. Fechin’s church. The device is a kite- shaped shield, on which is carved, in relief, two human arms, crossed, | coupé at the shoulder, and clothed with a short ‘‘ manche,”’ which de- scends from the elbows; the right hand grasps the handle of a large cross-hilted dagger, the point of which extends beyond the top of the No. 11. Monumental cross from the graveyard of St. Mary’s church at c | 149 shield, and on it is impaled a human head, of which the features are defaced ; resting on the shield, and beneath the left side of the head, is an ornament like the rowel of a spur. No. 13. View of the east window of the Anchorites’ church at Fore.* This building stands on the slope of the hill, just above the ancient church of St. Fechin, and its erection would date at about the early part of the sixteenth century ; 1t consists of a massive, low, square tower, having a small projection in its north-west angle to admit of circular sears, which led from the nave of the chureh, or basement floor of the tower, to the room over the arch, which was capable of being used as a dwelling, and was provided with a fireplace in the south wall. On the exterior of the north wall of the church is a small stone - tablet, bearing the following inscription, in raised Roman capitals :— “THE KIGHT HONORABLE RICHARD NUGENT EARLE OK WESTMEATHE AT HIS OWN EXPENCES REBUILDED THIS CHAPLE AND CASTLE FOR THE BURYING PLACE AND PIOUS USE OF HIMSELF AND HIS SUCCESSORS ANNO DOMINI 1680.”’ Above this, and carved in high relief, 1s an earl’s coronet, resting on a winged oriffin.

Plan of the same old church, showing the modern chancel, and the modifications of the original east gable. The walls of the ancient church are without foundations, but they rest on a rough basement or plinth of large flags. This peculiar mode of construction has been fol- lowed by the builders of the chancel, either from veneration or for con- venience. A large flat-headed doorway in the north wall of the chancel allowed access to this portion of the building, while a similar doorway in the central gable allowed of communication with the ancient or western D part of the building. No. 20. Near Foxhall, county of Longford, and in the parish of P| Rathreagh (Ordnance Survey, Sheet 20), there is an ancient mound, in the centre of which stands what is called ‘‘ The Caldragh Stone,”’ of q which this is a sketch. The monument in question, which is un- doubtedly of great antiquity, consists of a block of stone, five feet in a height, ten inches in breadth, flat at one side, and rounded on the © other, and standing in a flat circular plinth; its apex, for something 7 ) Te more than one foot, is fined off, and narrowed, or notched. This mo- nument is evidently incomplete, and I feel disposed to believe that the shaft was intended to receive a cruciform head of wood, which rested 4 on the notch at the top. No. 21. Close to this small pillar is a flagstone, bearing the ornament 4 here sketched; it consists of two circles, connected by a narrow band, © the central portion of the former being ornamented by a Greek cross. The stone is broken in the middle, and I have no doubt but that when | perfect there were three such circles engraved onit. This form of orna- ~ | ment, without the cross, is found on monuments of undoubted Pagan age in Ireland. Vide Vol. I., No. 14, of my “ Antiquarian Sketches,” where I have figured a slab of stone from the graveyard of Tully, inthe county of Dublin, in which we find this triple circle connected by nar- q a row bands, and which has been recognised as pre-Christian.

No. 24. Exterior view of the ancient window in the south wall of the nave of the same church. This feature is exceedingly interesting, as it shows the method adopted of closing the window with an external wooden shutter, a portion of the stone surrounding the ope having been cut away to receive it. Itappears to me that in this and similar examples we have the origin of the external mouldings, and subsequent decorations of all our windows. At first these necessary adjuncts to buildings of stone were merely loops; and as they were made wider in process of time, the benefit of light and air was often counterbalanced by cold and wet, and it be- eame necessary to close them externally by a shutter. A deep notch was therefore cut all round them to receive this construction ; and this notch, aiter the introduction of glassin our churches and castles, was retained as an ornamental feature, and enlarged, modified in shape, and decorated as taste and architectural skill suggested. No. 25. Interior view of the foregoing window, which shows that though the ope is triangular-headed externally, it is semicircular within —a feature which, I believe, is novel in windows of this class.

From the fact of the window loops and doorway in the interior of this tower being narrowed at the head by projecting bevelled stones, on which the flat head of each opening rests, I feel dis- posed to regard this tower as the work of the fourteenth century, pro- bably during the reign of Edward III.

There is a tradition pre- © served in connexion with this family and that of the O’Reillys and ~ the Edgeworths, which may be worth preserving; I believe that it is ~ founded on truth, and I know it is recognised as such by the family of — the Edgeworths. Some time about the early part of the seventeenth — century the Farralls and the O’Reillys owned large possessions on the eastern borders of the county of Longford; and as the country was ina | | very disturbed and unsettled state, the O’Farralls, trusting to what they © believed their superior interest and power, devised a plan by which” they might gain possession of the property of the neighbouring O’ Reillys. — On a stated occasion they invited the O’Reillys to a grand banquet at” their castle of Moat Farrall, and arranged the meeting so that each ~ O’Farrall had an O’ Reilly placed by his side at the table. Ata given — signal, during the progress of the feast, the O’Farralls stabbed each his — neighbour, so that not one of the O’Reillys left the banquet hall alive. Their success, however, was of short duration ; for scarcely had they seized the territory of the O’Reillys when the English Government sent a strong force to punish such an atrocity, and the whole of the O’Farrall property was confiscated, and bestowed on an English officer, named Edgeworth, who was instrumental in the punishment of the guilty clan; and since that period the Edgeworths have retained possession of ; the estate. .

View of the ‘‘ Minstrel’s Grave,” with Ross Castle and Crover Castle, with part of Lough Sheelin in the distance. I heard the following interesting legend relating to this locality, and I tran- scribe it from my notebook, as I jotted it down shortly after the recital :—‘‘ Can you tell me, » said I to an old man, named O’Reilly, who resides on the spot, ‘and who was passing along the byeroad leading to Ross Castle, ‘‘is that cross, standing on the summit of that mound of stones, placed in an ancient graveyard?” This I said, pointing to a small Calvary cross within half a mile of the castle. “ No, Sir,” said he, ‘‘itis not ; no onewas ever buried there but a gentle- man and a lady, and they were lovers; we call it ‘ the Minstrel’s Grave,’ for he was a great musician, and she was the daughter of the Black Baron, who lived in Ross Castle—but I may as well tell you the whole story, and it is as true as life. It was in the time of the great trouble that the Black Baron Nugent lived in the Castle of Ross.”’ “‘ What trouble do you mean?” said I. ‘‘ Sure, Sir, 1 mean the great war with the Ca- tholics in the time of King Charles, and it lasted for ten years.’ ‘The rebellion of 1641?” ‘True enough, Sir,” said he; ‘and the country had neither law or peace for all that time. We call it ‘the great trouble.’ Well, Sir, the Black Baron Nugent had a lovely daughter, and one day she went ‘boating on Lough Sheelin; and when she passed near the ‘castle of Crover, which you see standing on that little island in the lake, ‘she heard some one playing music and singing most delightful. She ordered the boatman to land her at the castle. Now, she was a Protes- tant; and though the castle was owned by one of the O’Reillys, who the a Catholic, and though there was no good blood between him and the Black Baron, who was a tyrant of a man, as I’ll tell you, yet the Lady Nugent was so kind and charitable, and so lovely, that all ‘the country round was very fond of her, and would do anything to ‘please her. Well, Sir, Lady Nugent looked into the castle, and there she saw an officer of the Catholics, who had been badly wounded, jand who had fled to hide in the castle of Crover. He was lying on a sofa, very weak and pale, and playing on a harp and singing, so sad and jsorrowiul, that the Lady Nugent took great pity on him, and fell in love }with him. His name was Irwin, and he was a colonel in the army of ithe great O’ Neill, and had just come from abroad in Spain somewhere, ito fight for the ould religion, and small blame to him. Well, Sir, Lady \Nugent used to go every day to the castle to attend the wounded jofficer ; but at last she found she could not be with him often enough ‘when the summer had passed, as she had to cross a couple of miles of ithe lake, so she had a house built for him in the thick woods on the 156 shore, under Ross Castle, unknownst to her father, the Black Baron, and she nursed him there till he died. Then it was that the Black Baron knew of his daughter’s love for the rebel officer, and he felt great grief to see how she pined and sickened at the loss of her lover. ‘ gratify her wishes, and m some way lessen her great afiliction, h allowed her to have the body of her lover buried on the top of the mound where you see the cross, just in sight of her own window in — castle. Not long after Lady Nugent died of grief, and her last request was that she should be buried m the same grave with him whom s had so tenderly loved, so that in death at least they might be unite and that is why the cross is placed over the Minstrel’s Grave. Now, Sir, I must tell you about the Black Baron, and how he died. He wa a great tyrant, and a wicked man, and he had all the law of the countr to jomeele whatever he liked should be done, and there was no one a check him or punish him. He used to hang the poor people for nothing, if he thought they vexed him. One day, when he rode infg the village of Fimnea,* he passed the cottage of a poor woman, and he heard her crymg and moaning, and he asked what ailed her? She told him that a beggarman from Connaught had asked her for a piece of the wheaten cake which she had been baking at the fire; and when she refused him, he took the half of it by force, and had gone away. The Baron, haying learned the description of the man and the road he had taken, set spurs to his horse, and soon overtook him, when he at once had him hanged on the nearest tree. Well, Sir, this poor man hadi brothers, better off than himself; and when they heard of how the Blz Baron had murdered their brother, they determined to revenge them- selves, and arranged the following plan of carrying it into execution = - Having heard that the Black Baron always wore along red cloak, and inl a white horse, they watted for a fair day at Finnea; and havi ing armed themselves with 4 pistol, and procured a fresh horse’s skin, the; went to the fair; as they were passing up the sireet, they heard ¢ lamentations in a house near hand; and, having entered it, they found woman aa tears, and greaily distressed. ‘What ails you, my g woman,’ said one of the brothers; ‘why are you crying so bitterly ‘ Oh, sure, and is not the Black Baron going to hang my husband) because he is not pleased with the way the poor man shod one of li horses this morning; and has he not sent off for some of his murderi ng people to come Bere and make mea widow? ‘ Whisht your crymg my poor woman,’ said the brothers, ‘there will nothing happen to you husband ; just g give us a drink of milk, as the day is warm, and k up your heart,’ The woman gave the boys a bowl of cream, and they left the house; ; they then took the road to Boss Castle, and, s enough, they soon saw the red cloak and white horse of the "Barons wh "0 L.- * Finnea in the “ Four Masters” is written (at 1330) Fiodh-an-atha, “‘ Wood of dl Ford.” In the early Taxations it is called Faweran. 157 s coming to the fair. As good luck would have it, he was alone; r he had sent word to the castle that some of his men should mect m at Finnea to hang the blacksmith. ‘ Now, then,’ said one brother to the e other, ‘do you keep silent, and watch your time, while I try to drag - the horse’s skin from you, and do you keep a tight hold of it.’ Just as the Baron rode up, the brothers began their mock quarrel. ‘ Oh, ush2,’ said the one who was pulling at the skin, ‘and is not the country . ne fo a pretty state, when a man may be robbed in this way on the ligh road! Is there no law or justice to be had anywhere for an honest man, who pays his money for what he wants? The Baron at this sd up his horse, and inquired the cause of quarrel. ‘ Sure, my lord,’ inc “brother who was tuggmg at the raw hide, ‘ did I not buy s horse’s skin from that fellow there at the fair, and now he stops me n the road, and wants to take it back, and he has my money for it.” e Baron was angry; and, leaning over his horse, he was about to smount to enforce justice, when the other brother placed the pistol o his bedy and gave him a mortal wound; he fell from his horse, and was then dispatched by a shot from one of his own holster pistols.

C., read the following paper :— Account oF OsHam INSCRIPTIONS IN THE CAVE AT RATHCROGHAN, County or Roscommon. THE principal remains at Rathcroghan, formerly the residence of the provincial Kings of Connaught, are indicated on sheets 21 and 22 of the Ordnance Survey Map of the county of Roscommon, and have been described in some detail by O’ Donovan in a note to his translation of the ‘¢ Annals of the Four Masters,’’ at A. D. 1223, and more fully in letters preserved among the MS. materials for the intended ‘‘ Ordnance Survey Memoir,” and now deposited in the Library of the Academy (14 F. 8, p. |91,.¢t seq.): Among these remains may be noticed on the map—310 yards north- west of the ancient sepulchral enclosure called Relig-na- Ree, or the Grave- yard of the Kings—a spot marked with the name Owneygat, thatis, the SE OPEe Sn oe ae 161 Cat’s Cave, of which the following account is given in the MS. letters above referred to :— “«There are two remarkable caves in the townland of Glenballythomas, of which the more remarkable is called Utha1o na 5caz, because wild cats used to hunt rabbits in it. I walked into this a considerable dis- tance, and saw its fine roof and hanging spars, like icicles, but will leave the description of it to geologists. The country people say that a woman followed a calf into this cave, and that she could not stop him till he came out at Keish Corran. I went as far into it as any one could, that is, untilit terminated in a cleft, not wide enough to admit my head. This, according to tradition, was the Bank of Ireland in the time of Queen Mab ; but if it was, the drops from the Gothic roof of the edifice must have injured the bank notes very much. A truer tradition connected with it is, that one Croghan, a rebel, lived in it after the rebellion, and by so doing saved his neck from the halter.” On examining this cave, on the 30th of September, 1864, the writer observed inscriptions in the Ogham character, on two of the roofing stones of its upper chambers or galleries. Part of the inscription on each stone was built into the structure, so that the stones before being placed must have been already sculptured. Whatever the age of the cave, the inscriptions must, therefore, have at least an equal antiquity. The cave has always, within literary memory, been regarded as of the epoch of Meave, the celebrated Queen of Connaught, who lived about the beginning of the Christian era. The Zain Lo Cuailgne, or Cattle-Spoil of Quelgny, commemorates an expedition led by this heroine of antiquity into Ulster during the reign of Conor Mac Nessa, whose death is made, in Irish traditionary history, to synchronize with that of our Lord. She was daughter of Hochaid Fidleach, by whom the principal fort, or royal dwelling at Rathcroghan, is said to have been erected. Her name, which popular tradition has impressed on a great number of places in Treland, is in its simplest form spelled Mrpsu, equivalent to Mrpr. Some one intimately connected with her family was called Frazcu. Such is the name given to her son-in-law in the ancient historical tract called the ‘‘ Twin-bo-Flidisi,” one of the introductory stories which constitute the preface to the Zain-bo-Cuailgne. She had many sons, by different fathers, and has left a vivid recollection of her name through- out the west of Ireland. That she lived at Rathcroghan at a period before the introduction of Christianity into Ireland is a fact which no one, in the present state of historical knowledge, will be disposed to deny. The earliest notices of the cave appear to treatit as a treasury house of Meave and her husband Ailill. It is so represented in the Zazn- bo-Aingin, another of the introductory or pre-tales of the Zain-bo of Queleny. Such also was the tradition of the country in 1838, when O’ Donovan made his communications to the Ordnance Office. The same idea still exists among the peasantry of the country, by whom the interior of the cave has been repeatedly explored within the last twenty years, in the hope of finding treasure. Their operations have resulted in 162 the falling in of the earth, which now chokes up the western end of the cave, and renders it impossible to say how far it extends. The writer is indebted to W. M. Hennessy, Esq., for the following further notes in reference to this cave :— ‘“‘Tn the list of celebrated places preserved in a stave of the ‘ Book - of Leinster,’ which is really a portion of the ‘ Book of Lecan,’ the cave of Cruachan is described as one of the three caves of Ireland,—the other two being the cave of Howth, and the Derg Farna, now known as the cave of Dunmore, near Kilkenny. This tract, from its language, appears to be of very high antiquity. | “‘ Tn the historical tale called the Zuin-bo-Ainghin, or the Cattle Spoil of Ainghin, preserved in the ‘ Yellow Book of Lecan,’ the cave of Cru- achan is referred to as the residence of a fairy community ; and some in- teresting particulars regarding the proceedings ofits denizens are related by a person who, for some slight to a fountain fairy, was condemned to a year’s residence therein.”’ It consists of a natural fissure in the limestone rock, which appears to have been artificially widened, so as to give an average breadth of five feet throughout a distance of about forty yards. This cavern, the floor of which is from fifteen to twenty-five feet under the surface, is connected with the upper chambers, in which the inscriptions exist, by a passage excavated in the rock, and roofed over, as are the external chambers, by long stones, artificially placed, and bonded into the dry stone walls form- ing the sides of the passages or chambers near the surface. Whether these upper passages be entrances to the cave, or chambers to which the cave itself served as an entrance, may be a matter of doubt. They are two in number—one forming a prolongation, ata higher level, of the na- tural cavern, the other opening upon it at right angles. Around these openings exist the remains of a tumulus of about twenty yards im dia- meter. The subjoined woodcut exhibits the general appearance and disposition of the parts, the dotted lines representing the underground constructions.

It is entered from a de- pression on the surface opening to the south, which bears the appear- ance rather of a breach made into the end of a chamber than of a pas- sage. About seven feet in length of the covered part remains. ‘The width is three feet eight inches; the height, from the clay which has fallen in, and forms the floor, not more than three feet three inches. At the junction of this crypt with the eastern opening, a species of tran- sept is formed, about eight feet by four, and four feet high, extending eastward into the remains of what has now the appearance of a passage, and opening on the western side into the narrow gallery formed in the rock, which descends by a series of inclines and rude steps into the prin- cipal apartment below. In this lower interior the natural walls of rock rise to a height of about eighteen feet, converging at top, and hav- ing much the appearance of the inclined passages in the Mexican pyra- mids. The spaces between the rock ledges at top are, as are the Vig. 2. upper passages and chambers, co- vered in with transverse blocks of stone. These stones, where they form the lintels at the junction of the upper chambers, have been selected with care ; and it is on the lintel stone of the southern crypt, marked A on the plan, where it abuts on what has been described as the transept, that the principal inscription exists. This stone, which 1s of the lime- stone of the neighbourhood, mea- sures four feeteightinchesin length, of which one foot is engaged in the adjoining masonry. It has an ave- rage breadth of one footfour inches, being somewhat broader towards the western end, and varies in thick- ness from four to nine inches. Its under surface is corrugated in the direction of its length with nume- rous natural striz ; and it does not appear to have undergone any pre- paration with the tool, except at one point, on the inner edge, at the eastern end, where it presents the appearance of having been rubbed down, so as to form two ribbed projections, separated by shallow grooved indentations, resembling the 164 analogous work on one of the stones of New Grange, which has been figured in Wilde’s ‘‘ Beauties of the Boyne and Blackwater” (p. 194).

Something of the same kind is also observable on one of the Ogham - inscribed stones in the Academy’s Lapidarian Museum, No.5. These indentations, whatever object they may have had, appear to indicate that this is the upper end of the stone, and raise a probable conjecture that it originally stood upright. They are not carried across the face of the stone, nor do they appear on the opposite edge. Seven, or possibly eight, Ogham characters exist on the external edge and face, and ten on the internal edge and face of this lintel. The external ap- pearance of the stone, with its inscription, is shown on the annexed wood- cut, Fig. 4. There is, at the right hand, detached from the inscription, an indentation on the edge-line of the stone, too faint to be relied on with any certainty ; but which may possibly be a single notch, standing for the vowel a. A circular disc or dot appears above this indentation on the edge near the end. This also is uncertain, and is not shown on the drawing. Two vertical strokes, connected with some curved inden- tations, apparently artificial, also exist on one of the stones forming the jamb or quoim of the passage on the right. They are too uncertain to be practically relied on, and are only hinted at in the woodeut. The cha- racter of these indentations has a general resemblance to that of some of the rubbed lines appearing on the stones of the chambers at New Grange and Dowth. Bi When first observed, the lintel was partly concealed by_a block of stone, constituting portion of the eastern side wall, and covering part of _ the final character at that end. The removal of this block enabled the writer to examine the whole under surface and edge, and to state that no further inscribed marks exist upon it. RAST; —— a i !

Before proceeding further in the consideration of these characters, it may be interesting to those members of the Academy who have not given special attention to the subject, that something should be said of the nature of the Ogham writing, and of the existing means for its de- ciphering. It was a species of cipher, in which straight strokes en- graved on monumental stones, by their number and relation to a parti- cular line, called the stem-line (generally formed by the edge of the stone), represented the letters of an alphabet. Facility of engraving with rude implements, rather than a desire for secreey—for who would desire to commemorate in signs not generally understood ?—may have been the original motive for the use of this species of writing. The value of the characters depending on the number of strokes, and these numbers increasing in a progressive ratio in sets of five—that is, five groups below, five above, five obliquely across, and five directly across, or on the stem-line—it is obvious, that if purposes of secrecy or curiosity were desired, the cipher might be made more or less abstruse by varying the number of the strokes; as by beginning with two or more at the commencement of each series; and a great number of ex- amples of such cryptic Oghams may be seen in the tract on this subject in the ‘‘ Book of Ballymote.” They are all, however, resolvable into the original key-cipher, in which each set of five commences witha single stroke; and which, with the other more complex examples, and certain arbitrary marks for vowel combinations, is also found in the same depository. With this key, available for the last five hundred years, we may be surprised to find the Ogham character still involved in somuch mystery. This may be, in some measure, accounted for by the discredit brought on the subject by a paper in our own “ Transactions,” at an early period in the history of the Academy, in which a supposed passage from one of the Ossianic poems was adduced in elucidation of an Ogham inscription existing on Callan Mountain, in the county of Clare 167 (‘‘ Transactions R.I. A.,” vol. i, Antiq., p. 3). The passage appears to have found its way into the text from a modern source; and the charge of falsification extendeditself, with questionable justice, as 1t seems to the writer, to the inscription itself. Added to this disaster at the out- set of the inquiry, were the really great obstacles arising from the sin- gularity of the names, and from the absence of any clue to the sequences in which the writing ran, whether from top to bottom, from left to right, or vice versd. It was not till our President undertook the investigation in the character on the scientific principles applicable to cipher-writing in general, that the subject again attracted a philosophic interest. His results, arising on independent analysis and comparison, are under- stood—for as yet the complete paper has not been published—to have come out in substantial accordance with the old key; and in a short paper in our ‘‘ Proceedings” (vol. iv., p. 358), he adopted and published the ‘‘ Ballymote Key,’’ which, with some slight difference, had also been given by Dr. O’Donovan in his “ Irish Grammar,” and by other earlier writers. Bit eran Te Soy ls) Be OL anes HALE LMM op) qe THA Hit aaa ie beleote 80°. n “46 ats ea Olu, vane In the course of these investigations our President early identified the group, an A ea reading Maqui, as the genitive form of J/ac, a son—a conclusion which _ was destined to receive corroboration of the most convincing kind from a source not then known to bein existence. The writer here refers to those monumental stones of Wales, which bear inscriptions in Roman characters with accompanying Oghams. These Oghams, rendered according to the key so furnished, have been found to yield results confirmatory not only of the alphabetic force of the characters, but of their proper se- quences and collocations, as indicated by the independent method of in- vestigation employed by our President. The Welsh Oghams so tested have, in fact, been found to resolve themselves into an echo of the correlative Roman writing. One of these inscribed Welsh pillars, which may be justly called the Rosetta Stone of the investigation, is in effect both bi- lingual and bi-literal. It commemorates in Latin words and Roman characters a person called Sagran, son of Cunotam, in the form (Lapis) Sagrant Fili Cunotam:. An Ogham on the edge of the same stone reads Sagramm Magi Cunotam:. Here we have Maqui as the equivalent of the Latin Fila; and must acknowledge the conclusion to be very cogent that 168 in Irish monuments of a cognate kind, wherever we find the combi- nation of Ogham characters which sounds ‘‘ M/aqi,” we may expect, before it, the name of the person commemorated, and, after it, the patronymic of that person. Such, in fact, is the formula of commemo- ration found on great numbers of the Irish Ogham monuments. The. writer instances in our own lapidarian Museum, No.7, Qunelogni Magi D « x *; Nocati Maqi, Maqi Rett « *, No.11; andin Mr. Du Noyer’s collection Logogt Magi Erenan (Du Noyer MSS. Lib. R. I. A., vol. i., No. 48). re Maqi Magerti, ibid., No. 27; Lafi cas Maqz Muce, ibid., No. 27); and numerous similar examples in the publications of the other Trish Archeological Societies. The presence of this well-known combination of strokes and notches, reading maAaqt, at the western end of the legend on the inner edge of the Rathcroghan stone, taken in connexion with the other indications of that being the lower end of the stone, and with the generally observed rule that these inscriptions read from bottom to top, and from left to right, leaves no reasonable doubt that the remainder of that line contains the patronymic, and the line on the opposite side the name, of the person com- memorated. Reverting to the opposite side, and reading it from bottom to top, and from left to right, and according to the ordinary key, it presents a combination of characters, of which — R-—cct are free from doubt, and of which it is not impossible that the three strokes occupying the place of the first blank represent r, and the notches occupying the place of the second blank stand for a1; in which case this part of the legend would read rraicct. The difficulty in respect to the first set of characters arises from a fracture of the stone, which leaves it in doubt whether the third stroke crossed the line ofthe edge. In that case, the reading would be omr—cci. The six notches represented by the second blank may either be a double v, or may read £0, or 0, or in any of the combinations of avo. ‘The name, whatever it be, seems to be in the genitive form, and to imply some such expression as ‘‘ the stone of” before it. Leaving this portion of the inscription, and coming to the patronymic, it is certainly startling to find it read, as it does in this collocation and sequence, without doubt or difficulty, MEDFFT, —that is, collating the several parts of the legend, ‘(The stone of) [ Fratc?] son of Medf.”’ The second inscription is found on one of the lintels covering the eastern passage, marked B on Fig. 1. When first observed, four of the characters and part of the fifth were hidden under the face of the stone, where it lay bedded on the southern jamb of the passage; and it was not until it was raised, and turned on its side, that they were, for the first time since the construction of the cave, offered to human ob- servation. ‘The appearance of the sculpture seems to indicate long ex- posure to the weather prior to the deposit of the stone ; and goes to sup- port the conjecture suggested by the ribbed appearance in the other, that Se es ee ee ee 169 both these lintels may have been monumental pillar-stones, brought not improbably from the adjoining cemetery of Relig-na-Ree. The inscrip- tion consists of eight characters, two of whch stand somewhat detached, yet seem to require collocation with the others to render an articulate sound. Fig. 7. _ iW LE aed - TT a a ~The Key-word Maar does not exist here to assist us; but a curved character occurring near the end of the group indicates that it is to be deemed under the stem-line, and that consequently the detached cha- racters above referred to are those from which the reading commences. The writer is not aware of any other example of the curved character in any existing monument; but it is one of the contractions given in the recognised Ogham keys, having the value of the vowels ur. The last cha- racter to the right is extremely faint, and the writer is unable to say with certainty whether it consists of three or of two indentations. It appeared, however, to the eye and touch rather to consist of three strokes and . these below the stem-line; but as F would not articulate with the next adjoining character (m), and the strokes are short and notch-like, he inclines to suppose it the vowel v, a not unfrequent termination of proper names in Oghamic writing. Taken in this sequence, the legend on this second stone would read QRAGUISMU. The writer is not aware at present of any corresponding proper name. Names beginning with the same combination are, however, found on some of the inscribed stones in the Academy’s collection, as QRITTALEGI QRITUMAH, on stone, No.5. In the absence of anything more satisfactory we can, therefore, conclude no more from this object, than that Ogham writing was certainly in use prior to the construction of the Cave of Curachain. But, as regards the lintel first described, the legend of ‘‘ Tihe Son of Medf””’ appears to stand plainly legible, according to the ordinary key, and in the ordinary course of collocation; and, taken in connexion with the place and its traditions, may afford a confirmation of the testi- mony of our old books to the use of alphabetic writing in the Ogham _ character at a period before the introduction of Christianity. 170 On the seemingly Latinized form of the inflections, and the feminine genitive in 7, the writer desires to submit the matter to more competent philologists; and, with regard to the probable age of the cave, and the appearance it presents of having had two entrances, refers to Keating’s tract on “‘ Early Irish Modes of Sepulture,” from the Zr Biorr-ghaethe an Bhais (‘ Irish Ossianic Society’s Transactions,” vol.1., p. 68, e¢ seq.), and in particular to the old poem there cited :*— Peanc aen oonuip o’flon 50 naot, Peanc 60 n-06 O6inp1b 00 mnaol.

From a small beginning, in the year 1786, our Society has steadily increased in numbers and importance, till it has attained the rank of a national institution ; and while the threefold object of its foundation has opened a wide field for intellectual exercise, it has produced the happy result of bringing together, from time to time, in friendly inter- course and united action, a large portion of the literary public, the variety of whose pursuits, or other accidental differences, might, but for such a medium of communication, have placed them in a condition of antagonism or indifference. With what measure of success the scientific and literary labours of the Academy have been conducted, it is not for its members to pro- nounce. But they may be permitted to apprise Your Excellency that in two collateral publications, the “‘ Transactions” and the “Proceedings,” are embodied the principal results of their investigations; and that these journals have a wide circulation at home, and among kindred in- stitutions on the Continent. The creation of a Celtic Museum, un- equalled in extent and variety, and the formation of a Library pecu- liarly rich in Irish Manuscripts, have also marked the growth of our So- ciety. The Academy has to record, with a lively sense of gratitude, the encouragement and favour it has received at the hands of successive Chief Governors of Ireland, and especially of Your Excellency’s illustrious predecessor, who, himself possessed of the most remarkable gifts and ac- complishments, was ever ready to assist the intellectual labours of others. We earnestly hope that one so noble-hearted and so richly endowed may long be spared to humanity and literature. We trust that Your Excellency’s administration of the high oftice committed to you by our beloved and most gracious Sovereign will tend, not only to promote the peace and prosperity of Ireland at large, but also to impart increased vigour and efficiency to her literary institutions; so that, while as subjects and citizens we enjoy the blessings of living under a just and able ruler, we may as an Academy experience the be- nefit of connexion with a Viceroy who has proved himself an accom- plished scholar and an enlightened statesman. To which H1s Excrtiency returned the following Answer :— Mr. Presrpent, AND GENTLEMEN OF THE Royat Irish AcaApEMY,— Amongst the various bodies which have presented Addresses to me on my assuming the office of Lord Lieutenant, I can say with truth that I have received none with greater satisfaction than the Royal Irish Aca- demy. A Society which has with so much success brought together the most distinguished literary and scientific men in Ireland, and whose “ Trans- actions” and ‘‘ Proceedings”’ enjoy a wide reputation at home and abroad, 172 would command my attention and support, even if I did not hold the _ official position of Visitor to the Academy. Though I have not yet had the opportunity of becoming personally acquainted with your Museum and Library, I am well aware of the im- portant and interesting character of those collections; and the care and assiduity with which you have gathered and preserved the relics of by- gone ages are at once a subject of congratulation, and a bright example to all who study the history of the ancient races of mankind. I shall rejoice if my connexion with the Academy should enable me to afford that encouragement to its labours which you derived from my accomplished predecessor; but I am conscious that my own literary ac- quirements are far too modest to entitle them to the commendation of so learned and distinguished a Society. G. Henry Kinanay, F.R.G.S. L, Senior Geologist of the Geo- logical Survey of Ireland, read the following Paper :— Norers on Crannocks In Baturn Loven.

When visited, it was about a foot above the surface of the water, and we excavated for over four feet in depth through peat without finding any traces of ancient occupiers; and as there are no stones round the outside of it, we came to the conclusion that it was not artificial. No. 2, or West Island.—This lies about 80 feet from the shore, to which it is joined during the dry season. It is of a rude oval shape, the diameters being about 383 and 15 yards; the outside is regularly covered with flat stones. Most of it was covered with water when it was visited; we therefore excavated in the centre, where we found— Section LVo. ie Ft. In, Bog and clay, with a fewbones,. .

On account of the height of the water and the porous nature of the materials forming the island, we could not make a careful examination ; but near the west shore, ees the island was a foot above the ace of the water, we made a small excavation, and found— : Section No. 2 Ft.

PROC.—-VOL. IX. ZA 174 The oak beams (No. 2, section 2) were evidently sawn, not cut with a chopping instrument. Through them, at about nine inches apart, there were pairs of dowels that were used to fasten the basket flooring to them ; these beams seem to run nearly N. and 8. In the basket flooring, at about every nine inches, were poles, 2°5 inches thick, through which the previously mentioned dowels went, and fastened the flooring to the beams. These poles seemed to be ash sap- lings, while the rest of the flooring was made of hazel rods. Below the beams there was peat, but it could not be examined on account of the quantity of water that rushed into the working. This Crannoge seems to have been divided into huts or apartments, as part of a row of ash piles, three inches in diameter, was observed. No stone or other implements were found, nor was it likely that there should, as only a small opening was made, and only a few feet of the basket flooring uncovered. ‘To find them, the Crannoge ought to be carefully explored during the summer, when the water would allow the bed lying on the flooring to be cleared out. SKETCH OF BALLIN LOUGH, LOOKING N. E. Fig. 2. The island in the middle distance is No.1, or North Island; that on the left hand, over which there are birds, is No. 2, or West Island; the island on the shore of which a boat is seen, is No, 3, or Middle Island; and a small portion ef No. 4, or East Island, is seen at the right-hand margin of the sketch. No. 4, or East Island.—This lies about 300 feet from the south shore, and is of an irregular pearshape, being about sixty-seven yards in length from north to south, and fifty yards in its widest part from east to 175 west. Round outside this island for about four yards in width there are regularly placed small flat stones; and at theS.-H. shoreof theisland (under the water at the time we visited it), there is an east and west beam seven inches wide. These things would seem to point to its being artificial; but we made various excavations in different parts of the island, and found no traces of ancient inhabitants ; an excavation in the centre of it gave us four feet of peat, under which was shell marl. From this I am inclined to think that this island may have been partly natural, and partly artificial. Ballin Lough occupies a hollow among low hills, the only exit from it being on the 8.-E., at the village of Ballinlough, where there is an artificial cut about four feet deep through a bank of coarse stony drift (boulder clay), about sixty yards wide. If this cut was filled up, the waters of the lake would rise at least four feet higher than at present; and that the water was at this level not long since, would seem to have been the case, as all round the lake to over that height there is a deposit of shell marl and peat. As the level of the water when the island was ex- amined was three feet above the basket floor in the Crannoge, it must have been at least seven feet above the floor before the cut was made through the bank of drift. From this we see that when the Crannoges were built, the water of the lake must have been at least four feet lower than in March, 1864, and at least eight feet lower than the height of the water before the artificial cut was made; how the waters could have been at that level we have now to consider. On the Ordnance Maps we find that the height of the lake is 356 feet above their datum level, and that a quarter of a mile to the S.-E., in the townland of Tulla, the surface of the stream is 340 feet. From this we see that if a cut was made from this point, it would lower the lake sixteen feet; or thirteen feet lower than the basket floor- ing of the Crannoge; and if we examine the stream, we will find that the rise from this point to the village of Ballinlough is only a few feet, while from the village to the lough it is very rapid, being over eight feet. From this we see that if there had once been a natural cut or ravine through this bank of drift from the village to the lake, the wa- ters of the latter would have been five feet below the basket flooring of the Crannoge. On examining the bank of drift on the west of the village, what may be the trace of an ancient ravine will be ob- served, which appears to have been artificially filled up with stuff taken from an oblong excavation, marked a on Fig. No. 1, about three or four yards wide, and about six or eight yards long, and that the ravine since it was filled up has been used as a road, which has helped to obliterate the old embouchement of the lake. To account for this artificial filling, I would suggest that the inhabitants of the Crannoge were flooded out by an enemy who stopped the egress of the lake, and thus raised the waters until the islands with the huts and inhabitants were swamped. The islands after this were submerged until the present cut was opened, 176 when they again appeared. In latter years they have been occupied by various individuals, generally for illicit distillation. In the lake the horns and skulls of the Red Deer have been discovered at various times, and the head and horns of the Irish Elk are also said to have been found; but for the latter there is no good evidence. ; T should be inclined to consider that these Crannoges are not as old as those which I previously described as occurring in Lough Rea; for in the Lough Rea Crannoges the piles and beams all appear to have been split, while in the Ballin Lough Crannoge the beams were un- doubtedly cut with a saw. ‘That there was an ancient settlement here- about, and that it was a place of note, seems to be proved by all the ancient remains scattered about, which will be seen on looking at the Ordnance Map (Galway Sheet, 125), as within a mile of the lake are thirteen Raths and Raheens, eight Cromlechs, and one Holy Well (Tober- macduagh). All the Cromlechs and the Holy Well le to the N.-W. in Marble Hill Demesne, the ancient name of which was Gortenacuppoge, e., ‘The Field of the Leaves;’’ and most of the Raths and Raheens lie to the N. and N.-E., only three (which are Raheens) on the south. At amore recent period it would appear that this neighbourhood was still a place of note, as about three miles to the north-east there are the ruins of an extensive abbey and castle, and a mile on the north are the ruins of a church and castle. The abbey may have been founded by St. Colman M‘Duagh, as the Holy Well previously mentioned is dedi- eated to him. I may here mention that Sir W. Wilde, in his list of recorded Cran- noges in the Catalogue of the Royal Irish Academy, says :—‘‘ Even so late as 1610 we read of Crannagh Mac Knavin, in the parish of Tynagh, barony of Leitrim, and county of Galway.” I could find no trace of this Crannoge; but I imagine its site must lie somewhere in the large allu- vial flat and bog which occupies the country south and south-west of Crannagh, the seat of R. Nugent, Esq., which is in the parish of Tynagh, and barony of Leitrim, and lies about half-way between Portumna and Marble Hill. It is remarkable that, although it was inhabited up to so late a period, and that the descendants of the sept of the Mac Knavins still live thereabouts, I could find no tradition about it in the neighbour- hood, and the only trace the name of Mr. Nugent’s place. These flats and bogs, somewhere in which I suppose the site of this Crannoge to be, lie between four and five miles E.-N.-E. of Ballinlough, where are situated the Crannoges which the Notes just read refer to. The following paper was also read :— Notes on a Crannoce in Loven Nanincn. By H. B. Trencu, Ese., and G. H. Kinauay, F. R. G.S. 1. Loven Naurncg, 1. e. The Lake of the Island, lies on the junction of Tip- perary and the King’s County, the Crannoge being situated in the former, barony of Lower Ormond, parish of Ballingarry, Sheet 11 of the Town- 177 land Survey of Tipperary, and Sheet 135 of the One-inch Ordnance Map of Ireland. . This lake les in a large bog basin (see Geological Map of Ireland, Sheet 135 and Map Fig. No.1), and was formerly much larger; but previous to the year 1812, its outlet to the N.-W. was lowered, and the land about it reclaimed. In winter its limits extend much farther than during the dry season, as the ground about it 1s low. The appearance of the Crannoge has been much changed since the . lake was lowered, as on its south shore a quay was built on which to land turf cut in the peat bog on the south, and many of the piles that surrounded the Crannoge have been removed, and its circular shape changed. Our attention was first directed to it by the following notice in Wakefield’s ‘‘Ireland,” which was published in 1812:—“ In the highest part of this reclaimed land, which is about the middle of the old lake, there is seen a circular part, in shape the top of an immense tub, about sixty feet in diameter. The large planks which form the staves are from one to two feet broad, and about six inches thick, quite straight as far as it has yet been possible to trace them downwards. None of them have yet been raised without cutting them. At present there is no appearance of either ax or saw having been used in the formation of them.” When the island was visited in March and August, 1864, it was found to have shallow water all round it, except at the south, where the previously mentioned quay was built; on the east there is a track into the mainland (C on Map Fug. 1), that may also be of modern construction ; at all events, it was used at the same time as the quay, and has been repaired from season to season, by laying branches and trunks of trees across it, and covering them with gravel. At the junc- tion of this track withthe quay at the §.-E. of the island, one of the old oak sheeting piles was remarked, the section of it being 4 x 12 inches. On the north of the island more of these piles were noted, forming part of a circle; and from them, running 8. and 8.-E., are two rows of round perpendicular ash piles, 2°5 inches in diameter, that appear to have been parts of two partitions or walls that divided up the space inside the eircle of sheet piles into rooms or habitations. On the N.-W. of the island, about three yards from the present shore, are also some of the circle of sheet piles, and between them and the land are, E. and W., beams about four feet apart, and about four feet lower than the surface of the island. There are also above these, and close to the edge of the island, irregularly laid logs of oak, on an average about five inches in diameter, mingled with large stones. On the S.-W. of the island there is a set of oak sheet piles bounding the end of the quay; these seem to have been recently put here, and may have been some of those men- tioned in the extract before quoted, ‘‘ that were raised’’ when the quay was built, and were redriven here to protect the pier. There are also ‘a few other piles, but they are evidently modern, being round fir sticks, which appear to have been used to fasten the boats to. 178 LOUGH NAHINCH.

On the beams (Led No. 2 in Section) there seems to have been a basket flooring, but of this we could not be certain, on account of the depth of water in 179 the excavation ; but in connexion with them we observed wicker walls, made of hazel rods. Where the wicker walls cross the oak beams, there were round holes through the latter for the stakes to go through. In the vicinity of these beams asmall rude stone implement made of Silu- rian grit was found, but it was so rotten, that it broke while the dirt was being removed from it. The beams in bed No. 3 were charred on the under surface as if they had been the beams which supported the roof of an edifice that was de- stroyed by fire; near the north of the island, immediately over these charred beams, there was a N.-W. and 8.-E. plank about ten feet long, twenty inches wide, and two inches thick ; at about one foot nine inches from its N.-W. end there were two holes through it, four inches by two inches, that ran north and south in a line with the north and south piles seen on the north shore, and on each side of the plank were upright stakes ranging in the same direction. In bed No. 5, near the centre of the island, a large heap of wood ashes was found, and innumerable quantities of hazelnut shells and a few of walnuts. The bones found in the different beds seem to be those of pigs, sheep, and cows. From the facts we were able to collect, we may draw the following conclusions:—That the base of the artificial work is more than 5:5 feet, below the present surface of the island ; that it was inhabited at least at two different periods, the first of these being when the east and west beams formed the floor of the habitations; those habitations seem to have been destroyed by fire, which would account for the charred beams. After this period the oak sticks and stones irregularly laid were placed to form a floor for new habitations. Between these periods we must suppose that the waters of the lake rose considerably. Within a mile of Lough Nahinch we find that there are the remains of nine raths and raheens in the county of Tipperary, and five or six in the King’s County; that there were more would seem likely, as the name of the townland on the south of the lake is Lissadonna, and yet there is now no trace of a diss or rath in it; and in other places raths are said to have been levelled with the ground. ‘The old castle at Bal- lingarry lies about a mile N.-W. of the lake ; it may have been built to prevent the natives from re-occupying their island home. The Very Rev. the PresipEnt read a paper On InscripeD MonvuMENTs IN THE County or Kerry (Lately discovered by himself and his son, Mr. Alfred Graves). THE monuments now brought under the notice of the Academy appear to be nearly related to a class which formed the subject of a paper read by Dean Graves to the Academy in February, 1860. The monuments _ then described exhibited inscribed circles, or groups of concentric circles, having at the centre small cup-shaped hollows, of from two to four inches 180 in diameter. The monuments to which attention is now directed present numbers of the cup-shaped hollows, unaccompanied by circies. Five of them are the covering stones of large cromlechs, and Dean Graves thinks that there is reason to believe that the hollows were de- signedly arranged in certain alignments. The monuments, however, have been so much defaced by the action of the weather during hun- dreds, perhaps thousands of years, that it is hardly safe as yet to insist positively upon this point. Dean Graves remarks that the occurrence of these symbols on what are undoubtedly sepulchral monuments may help towards the discovery of their signification. A huge block, found by Mr. Alfred Graves, at Loher, near Darrynane, and exhibiting some of these hollows, serves as the covering stone to a sepulchral chamber excavated in the earth under it; a narrow covered gallery, of twenty-four feet in length, constructed in the ordinary way, leads to the subterraneous chamber. Though careful search was made in it for human or other remains, nothing was found, with the exception of a few fragments of charcoal, and a portion of a charred bone. = S Tn a i ~~, rn erent Scale, {3th of an inch to 1 foot. The other monuments described in Dean Graves’s paper were found in the following localities:—One in the island of Valencia; another, near Cahirciveen; a third, near Waterville bridge; and two more, near Sneem. The Dean concluded by expressing his expectation that artificial hollows would be found on many of the co- vering stones of cromlechs on which they have not been yet observed, simply __ be- cause their ex- istence was not suspected. Where the surface hag been much af- fected by the weather, any hollows that appear may be readily mista- ken for natu- ral ones; but hollows that are certainly artificial hay- ing once been recognised, the eye of the an- tiquary will be prepared to observe those which are not so obviously the work of man. Dean Graves noticed some other _monu- ments in Ker- ry which ex- hibit circular hollows, but do not admit of being class- ed along with those describ- ed in this pa- per. RB. 1g A. PROC.—YVOL. IX.

WaALrer, LL. D., Vice-President, in the Chair. P. Joseph Keenan, Esq., was elected a Member of the Academy. Denis H. Key read the following paper :— Description oF Two Irish MS. Tracts By THE CELEBRATED DvaLp Mc Frepis, TRANSCRIBED BY W. Hennessy, Hsa.; AND PRESENTED BY HIM TO THE Roya IRIsH AcaDEMY, THROUGH D, H. KeEtty, MS REA. Mr. PresIpENt AND GentTLEMEN,—Mr. William Hennessy has intrusted to me, for presentation to the Academy, this small Book, containing faithful transcripts, with the contractions resolved, of two Tracts com- piled by the celebrated Duald Me Firbis, the Amanuensis of Sir James Ware, the originals of which are preserved in the Bodleian Library, at Oxford, where Mr. Hennessy discovered them in the month of August last. The MSS. from which these copies have been transcribed are in the beautifully minute and well-known handwriting of the learned and industrious D. Mc Firbis; and, although their contents are comprised in the small volume which I now submit to the Academy, the labourers in our wide field of Irish Archeology will, I believe, find in them much that is well worthy of careful examination. I feel some gratification myself in having suggested to Mr. Hennessy the importance of a careful examination of the Irish MS. collections in both the British Museum and the Bodleian at Oxford, on the occasion of his kindly undertaking for me to collate my transcript of an Irish MS, in which I am interested with its original in the British Museum; and I believe that the volume which forms the subject of my obser- vations this evening is only an instalment of the fruits we may look for from Mr. Hennessy’s visit. It will be unnecessary for me to trouble the Academy with any ob- servations on the character of Duald Mc Firbis, and the nature of his contributions to Irish history, topography, and genealogy. It is well known that he was the lineal descendant of the learned compilers of the Book of Leacan, the hereditary ollamhs in history and genealogy of the Hy Frachrach of the Moy; and those who wish for further infor- mation on the subject will find it on referring to our friend Dr, Petrie’s Notice in vol. xviii. of the Academy’s ‘“‘ Transactions,” of our lamented friend O’ Donovan’s archeological volume on the Tribes, &c., of the Hy Fiachrach; and to our equally lamented friend Eugene 7 ae a 183 O’Curry’s Lectures, in which such particulars of Mc Firbis’s life and writings as were then ascertainable have been faithfully set down. I may observe, however, in explanation of the manner in which his MS. collections became so widely dispersed, that after the death, in the year 1666, of his patron Sir James Ware, of whose house he had for for some time been an inmate, he appears to have returned to his na- tive place in the county of Sligo, leaving most, if not all, of his MSS. in the hands of Sir James Ware’s son and heir. It is pretty generally known that all Sir James Ware’s MS. collec- tions relating to Ireland were purchased from his son Robert, in 1686, by Lord Clarendon, then Lord Lieutenant of Ireland. After his Lordship’s death they passed by sale into the possession of the Duke of Chandos, whom the witty and public-spirited Swift, Dean of St. Patrick’s, in vain solicited to deposit them in the Library of Tri- nity College: his letters are given in the recently published correspon- dence of Mrs. Delany (Mary Granville), to whom he thus writes in October, 1734 :—- “‘ Are you acquainted with the Duke of Chandos? I know your Uncle Lansdowne and he were intimate friends. I have known the Duke long and well, and thought I had a share in his common fa- your; but he hath lately given me great cause of complaint. “\ — —— a SS SS = ~ Lan oft) By use?

Jo is often a compound relative; and this has been mistaken for its real character by Dr. Forbes, who says, p. 117, d— ‘‘In many instances the relative jo corresponds with our ‘ who,’ ‘which,’ or ‘that;’ but the student must be careful not to consider this as a rule, for it is only the exception ; as follows :— do rote jo bete khate hain, the two loaves which my children eat.” It is quite obvious that jo is here the simple relative ; and the re- mainder of the Doctor’s observations lose sight of the question altoge- ther. If need be, the employment of wuh in the leading clause will make the matter plainer :--wuh Lars deta hun, these I lend. The judg- ment of Dr. Forbes is entirely inconsistent with the frequent accompa- niment of the actual antecedent, and the ordinary presence of a corre- lative; its reverse is the truth. But in No. vi. js is clearly a com- pound relative, to be rendered by ‘‘by him by whom.” In No. vii., jo may be regarded either as a simple or a compound, according as we take so for the antecedent; or for the emphatic correlative, if we suppose yo understood; and there is nothing in the language itself, or in the ge- neral principles of Grammar, to prevent either view. As in the last sen- tence, so in all the others, itis a pure relative—in the first two instances followed by the antecedent, but in the rest preceded by it. 2 I VES ye ee Cott (Eh Lhe © lay syleste 5 see ~ w IS Vil.

To any one never address such an assertion as may be believed (only) after the expiration of a year. 6. So. Passing by the use of iv for so, and a few other particulars stated well enough in any Grammar in use, I must direct attention to the occasional service of so as a compound relative. I have also to ob- serve that such a fact favours the opinion that yo, as such, is a license, although of frequent occurrence ; but the true character of yo has been independently established. When in its compound character, so usually 266 appears between two verbs, to both of which it may supply subject or object. The subject is, to a Kuropean, sometimes curiously expressed, as by log, in No. x. ix. I shall tell what I heard. Gy ~ 4 x. The people (or they) who went, & Q Sie \ s¥) pe es age saw him. In the last case, however, so may be viewed as a simple relative. Much more that Forbes has written about the relative exhibits very loose criticism; but Iam restricting myself to points of absolute utility. T shall close this paper with a few words about sa and manind, or md- nand. 7. Sd. The regimen of this adjective (needlessly called a particle) — is not properly stated by any of the grammarians. In Dr. Forbes’s Grammar, p. 108, we read— ‘When added to an adjective, it seems to render the same more intensive, though frequently it is difficult to find for it an equivalent Sm English expression; as 4 ? ul (ies \) gi ‘bring a little water ;’ ue ys eyed gt Cane ‘there were many weapons there.’ When the comparison made by \., alludes to one thing out of many, it go- verns the genitive case; as in the sentence — ‘you also have a body exactly like ge pe Ls ane Jl a4 ws their’s, oe < g a form like that of a tiger.’ ”’ ae se oad a oe In the face of this correct translation, the statement of the construc- tion is surprising indeed. It would be more literal to write, ‘‘your body is like their body.’”’ It is quite clear that sd, ‘like,’ agrees with jzsm, which is masculine; as tumhara also does. Tn like manner kd, which agrees with yusm understood, has this form, both because y2sm is mascu- line, and in the nominative case. If sd were absent, we should have ha just as it is, according to the rule for this sign or element of the Hin- dustani genitive construction. In the same way, in the last sentence, ~ ki 1s governed by the feminine surat, which in like manner governs s7?. 0 that sa has no influence whatsoever over the genitive sign. 267 ‘ > 8. As to Dr. Forbes and others calling sda an intensive, when asso- ciated with an adjective, I never met an example which could lead me to that conclusion. In such expressions as thord sa pani ld, 0 ; bahut se hathyar wahdn the, &., sd serves as a limitation or restriction on the main idea; and, therefore, such phrases must be understood thus :— ‘bring rather a little water ;’ ‘a good many (not very many) weapons were there,’ &c. To put an end to debate upon this trifle, I lately obtained the opinion of gentlemen long resident in India, and also of Mir Ali, through a very able pupil of his, with whom I corresponded when in the country. 9. anand. Of this preposition Dr. Forbes writes, p. 98——‘‘ There is one peculiarity attending some of the feminine prepositions . ... We have excellent authority for saying that mdnand (and three others), when they precede the substantive, require the genitive in ke; and when they follow, they require 4%.” Professor Williams merely says that manand, bamadad, and taraf may take £: when they follow the re- gimen—ZAntroduction, p.53; and Mr. Shakspeare, Grammar, p. 79, note, speaking of manand in this situation, declares itis sometimes constructed with fe, and sometimes with /v. The latter is certainly the ordinary construction, but not the only one. An instance of ce occurs in Fable 5 of Shakspeare’s Muntakhabat-i Hindi: us ne us yawdn ko auron ke ma- nand khiyal kiya. Sir W. R. Wilde made a presentation of, and a described, a collection of Animal Remains and Flint Implements, found in the cave at Perigord by Messrs.

Durine the Easter Recess of 1864, I had an opportunity of explain- ing to Professor Gratiolet,* of Paris, the investigations I had made with respect to the mechanism of the leg of the Ostrich and the theory I had formed to explain it. This distinguished anatomist did me the honour of approving of my explanation, and urged me to pro- cure a Crocodile, in the posterior limb of which he assured me I should find a mechanical problem exceeding in complexity that presented by the leg of the Ostrich, and as yet unsolved by anatomists. During the month of March last I was furnished with a young Cro- - codile from Egypt, by Mr. Thomas Moore, Curator of the Derby Mu- seum, Liverpool, to whom I had communicated my earnest desire to have an opportunity of dissecting such an animal; and the results of my examination fully bear out the anticipation of Professor Gratiolet, and also furnish a complete confirmation of the principles I made use of in my theory of the leg of the Ostrich. The interlacing of tendons in the hind leg of the Crocodile is very remarkable, and more complex than in the Ostrich, although in one respect it somewhat resembles it. * The incalculable loss that science has sustained in the early part of the present year by the premature death of this gifted anatomist, is exceeded by the loss experienced by his friends, to whom his genial social qualities endeared him even more than his brilliant scientific attainments. I extract from the “‘ Journal des Debats” of the 19th February, 1865, the following just tribute to his memory :— ‘Les sciences viennent de faire une perte aussi cruelle qu’imprévue; M. Gratiolet, professeur de zoologie a la Faculte des Sciences de Paris, a succombé hier matin a une attaque d’apoplexie. ““M. Gratiolet n’avait pas cinquante ans; avant-hier, encore plein de vie et de santé, il travaillait 4 son laboratoire du Muséum (histoire naturelle lorsque, a deux heures, frappé dune congestion subite, il dut étre ramené 4 son domicile; quelques heures plus tard, il avait perdu connaissance; hier matin a quatre heures, il rendait le dernier soupir. “‘ Nous ne saurions peindre l’emotion profonde qu’a causée dans le monde scientifique lannonce de cette mort prématurée. M.Gratiolet était aimé de tous; son affabilité, la droiture de son caractére lui avaient concilié toutes les sympathies. “Ses travaux d’anatomie comparée, ses recherches sur le systéme nerveux et sur le cerveau, etc., l’avaient mis au nombre des naturalistes les plus distingués de notre pays ; son merveilleux talent d’élocution l’avait placé au premier rang parmi nos professeurs les plus renommés, et l’aptitude de son esprit pour les études métaphysiques avait im- primé a ses ceuvres un caractére d’originalité qu’appréciaient les philosophes aussi bien que les savans. “Ta mort est venue le frapper au moment ou, aprés de longues années de lutte, al semblait sur le point de recueillir le fruit de ses laborieux efforts. ; *¢ AimE GIRARD.” 269 Part I.—Dzisskction oF Lee oF CRocopDILE.

The interlacing of muscles in the thigh and leg of the Crocodile, just described, is very remarkable, and more complicated than that found even in ‘the Ostrich; and at first I was disposed to think that it threw some doubt on the explanation I had given previously of the reason for such an arrangement in the bird’s leg. In the case of the Ostrich the necessity for strict simultaneity of action was made evident by the great force of the muscles employed, and the great delicacy of the bones on which they had to act. What could there be in the case of the Crocodile to correspond to such a peculiarity in the case of the Ostrich? After some careful dissection I found the ready answer to my question in the remarkable muscle which I shall now describe. On clearing away the superficial muscles of the thigh and tail, I found the enormous mass of muscle, figured at 6, Fig. (20), which acts as the chief and powerful extensor of the thigh. Die eraser femoris caudalis (b),* .°.. 2. . ~.«.«) 181 o7. Origin; from the transverse and inferior spinous processes of the caudal vertebree, from the 3rd to the 15th, inclusive. Insertion ; into the back of the upper part of the femur, and into a great round tendon, which receives, in particular, the anterior fibres of this enormous muscle, and, passing down the back of the femur, is inserted by a strong common aponeurosis into the outer condyle of the femur, and into the head of the fibula. This com- mon aponeurosis also gives a partial origin to the gastrocnemius (a), Fig. 20, and to the plantaris (x), Fig. 19. * This remarkable muscle is noticed and accurately described by Meckel, in tome iii., pp. 152, 153, of his “‘ System der vergleichenden Anatomie” (Halle, 1828); but it is very strange that he transposes its origin and insertion, and seems not to have had any idea of its real use. Itis regarded from his point of view as a descriptive anatomist, and without the remotest reference to its final cause. He says:—‘‘ Der zweite, tiefere weit dickere Muskkel is yon dem ersten [the superficial muscle of the tail] wie einer breiten Binde umgeben, entspringt mit zwei ganz getrennten, 1) einer weit kurzern, breiten,Sehne oben von den hintern Flache des Oberschenkelbeines; 2) durch eine weit langere, schlanke, unten zwischen den beiden Gelenkknorren desselvben Knockens, und setzt sich an die ganze Seitenflathe der untern Dornen, so wie der Zwischendornenhaut und die uniere Flache der Wurzeln der Querfortsatze.’”’ LX) ~I Li) There are two muscles, ac- cessory to this great caudal ex- tensor in their action, which are as follows :— 12.

Epwarp Hiners :— On THE VARIOUS YEARS AND Montus 1n Usk Amone THE EGyPrTraAns. Tue author began by referring to his former paper on a similar subject, read before the Academy in 1888, and published in its ‘“‘ Transactions.” The conclusions arrived at in that paper were, he observed, vitiated by a discovery made by Brugsch, that Champollion had mistaken the sea- sons of the Egyptian year; that the third season, which he had be- lieved to be that of the inundation, was in reality the genial season; and the first season, which followed this, was the true season of the inun- dation. Fully recognising the importance of this discovery, and of others made by Brugsch, Dr. Hincks could not acquiesce in what he had put for- ward as his latest discoveries—namely, that the wandering year of 365 days was unknown to the Egyptians; and that the only yearsused by them through the whole period of their history were the sacred year, com- mencing with the rising of Sothis on the 20th or 21st July of our pre- sent calendar; and the civil year, commencing about forty days after. Kach of these had 365 days in three successive years, and 366 in the fourth. The principal object of the present paper was to controvert — these new opinions. He admitted the existence of such a sacred year as that of M. Brugsch; which, however, was not a discovery of his, but what all Egyptologers have long since recognised; but he main- tained that the Egyptians had a civil year of 365 days since 2783 B.C., and that they never had acivil year with intercalations, beginning near the end of August, until after the taking of Alexandria by Czesar Octa- vianus. In support of the first proposition, he appealed first to the tes- timonies of various astronomical writers, and of Censorinus. In the course of his argument he noticed the mistake which Brugsch had 299 made respecting an astrological Papyrus at Paris, which he assigned to the tenth year of Antoninus, the real date being the jirst year of An- toninus; and the positions of the Sun, Moon, and Saturn noted therein being certainly those which they occupied on the 4th December, A. D. 137. This correction cuts at the root one of M. Brugsch’s principal ar- guments. Dr. Hincks then digresses to the consular fasti, which, as generally received, are inconsistent with this date existing in a contem- porary record. He points out a consulship in the reign of Vespasian, which has been, he thinks, improperly inserted, and one in the reign of Alexander Severus which has been improperly omitted. He then con- siders the testimony of 8. Clemens Alexandrinus, whose dates respect- ing the birth and death of our Lord can have no significance unless the years which he uses were years of 3865 days without intercalation. Admitting this, his dates of the birth and crucifixion of our Lord, of the taking of Jerusalem, and of the death of Commodus, are found to be dates of the wandering year, corresponding respectively to the 5th January, 3 B.C.; 7th April, A. D. 380; 2d September, A. D. 70; and 3lst December, A.D. 191. The second of these dates, it is ob- served, is that of Bishop Ellicott. The double date on the Rosetta Stone is then considered; and it is shown, by a reference to Archbishop Ussher’s work on the Macedonian Solar Year, that it is in perfect harmony with the Egyptian date, being that of the wandering year, and quite inconsistent with its belonging to a fixed year, such as M. Brugsch has imagined. Dr. Hincks then goes back to the time of the seventeenth or eighteenth dynasty, and endeavours to show that the Turin Book _ of Kings, which he refers to that period, recognises the wandering year of 865 years, as well as the year of 860 days, which is always meant in the Turin Papyrus when a year is spoken of. He observes that the 2291 years, four months, and twenty days, which the Papyrus gives as the length of the reigns of the sovereigns whom it enumerates, if they be reduced to days, at the rate of 360 in the year, give precisely 2250x365. He observes, also, that if 2260 be subtracted from 8555, which Manetho states to be the number of years between the accession of Menes and the final conquest of Egypt by Ochus, the remainder is 1295, the precise number of years which elapsed between the accession of. the seventeenth dynasty and the conquest of Egypt by Ochus, according to the restoration of the text of Manetho which Dr. Hincks had put for- ward in January, 1863. He maintains that 1634 B. C. (1295 years before Ochus), is the historic date of the accession of the seventeenth dynasty; but demurs to the 2260 years alleged to have intervened between it and the accession of Menes, as it does not yet appear on what grounds this number was fixed upon by the Egyptians of the six- teenth or seventeenth century B.C. There is good reason, he says, for thinking that some kings mentioned in the Papyrus were contemporary with others; and, as yet, there is no proof that in making this calcu- lation the Egyptians allowed for their being so. He observes that the seventeenth dynasty of Manetho is not represented in the Papyrus of 296 Turin, nor is any that follows it; but all the preceding: dynasties, which the Papyrus recognised as real and distinct, have their kings re- corded in it. The Papyrus, however, has only ten of the sixteen dynasties of Manetho—namely, the first, the second; the third and fourth, thrown into one; the fifth, the sixth, the eighth, the eleventh, the twelfth, the thirteenth, and the Shepherds. Dr. Hincks: ‘believes that the whole of the second, and the greater part of the first“and fifth dynasties of Manetho, were contemporary with the third and fourth; and has great doubts ‘whether the eighth and eleventh, and again the thirteenth and the Shepherds, were not to some extent contem- poraneous. The Sothic, or sacred year, is then considered; and it is shown that it began on the 21st July in the two years before the Augustan bissextile, and on the 20th in the bissextile year and that which next followed it. It began on the same day with the civil year in the four years, A. D. 134, 185, 186, and 137, deviating from itin A. D. 138, when the civil year began onthe sixth of the epagomene. This was counted as the first year of the 3rd canicular cycle, the other two having commenced on the 20th July, B. C. 2783, and 1323. The Sothic year must have su- perseded the still older year which began at the summer solstice, or at the beginning of the inundation, when this event occurred at the heliacal rising of Sothis—that is, as very roughly calculated, about 3200 B.C. The Egyptians had also, it is next observed, a lunar year, beginning at the new moon which next followed the summer solstice. This year was of very great antiquity, and was in use at the same time with the better known, fixed, and moveable years already spoken of. Dr. Hincks thinks that there was also a wandering lunar year, like that now used by the Mahometans, in use in Egypt. It seems to be referred to in some very ancient inscriptions, and also in the Calendar of Esneh, in which three days are mentioned as new year’s days, and on that ac- count observed as festivals. M. Brugsch only attempts to explain one of these ; M. Mariette differs as to this from M. Brugsch, but attempts to explain a second. Dr. Hincks maintains that MM. Brugsch and Ma- riette haye not only failed to explain all the commencements of years, but have given false explanations where they gave any. He explains all the dates as follows:—Supposing that the calendar belongs to the Sothic year which began 21st July, A.D. 108, the first day of this was a double festival, being the commencement both of the Sothic year and the regular Tunar year. The ninth day of the year, 29th July, A.D. 108, was the first Thoth of the civil year; and the 296th day of the year, ten lunations after the first, was the commencement of the wandering lunar year, 11th May, A. D. 104. The 21st July, A. D. 108, was the neomenia, according to the Egyptians, the conjunction of the sun and moon occurring that evening. A Karnac inscription of the Ptolemaic period speaks of the moon god being conceived on the first day of the month, born on the second, and attaining his maturity, or 297 beginning to decay, on the 15th. These three month dates refer, of course, to the conjunction, first appearance, and plenitude of the moon. The 16th of the lunar month was oftener than the 15th regarded as the day of full moon; and two monthly festivals, celebrated on the 1st and 16th, have been rightly referred by Lepsius to the lunar year. Dates of the lunar year are, according to Dr. Hincks, occasionally met with on the monuments. Such dates are, he thinks, those of the Ist and 16th of Athyr, of the 11th of Amenhotap ITI., mentioned on a scarabzeus, so as to imply that the Nile was then rising, and near its height. The date of the Exodus in the month Abib, presumably Epiphi, is also referred to a lunar year. The month Abib is identi- fied with what was afterwards the first month of the Israelites, and was, therefore, like this, a lunar month; and we know that it was the month which began at the new moon following the vernal equinox. Epiphi was the eleventh Egyptian month; the lunar Epiphi would, ' therefore, begin more than 295 days after the solstice, while the vernal equinox was about 271 days after it. From this it follows that the first Hebrew month would in general coincide with Payni, the tenth Egyp- tian month; but that it would occasionally coincide with Epiphi— namely, when the new moon followed the summer solstice very closely. This would furnish a means of determining the year of the Uxodus accu- rately, if it were known approximately ; for example, 1491 B.C. could not be the year of the Exodus, but 1494 B.C. might. But, what is of more consequence, the remark respecting the month Abib is a very strong argument in favour of the genuineness of the Biblical account of the Exodus, which has been recently called in question. No forger of a later age, and who had not lived in Egypt, could have thought of making such a statement. The President read a paper, by Professor Sylvester, ‘‘On the De- monstration of Newton’s Theorem respecting the Imaginary Roots of Equations.”’ The PrestpEnt read the following paper, with a Norz by the late Sir W. R. Hamittron, LL. D. :-- On a THEOREM RELATING TO THE Brnom1AL CoEFFICIENTS. Towarps the eud of March, I communicated the following theorem to Sir William Rowan Hamilton :— Putting s) = % +”, + % + &c., 8 = M+ m+ nN, + &e., Ss = N+ 25+ N+ &C., Where 7%, ™, &c., are the coefficients of the development (1 + x)” = myx? + my0' + nx’ + &e., and ” is a positive whole number ; 298 we shall find that, of the three quantities, s, s,, s,, two are always equal, and the third differs from them by unity. I mentioned at the same time that I had arrived at theorems, ana- logous, but less elegantly expressed, by summing the series formed by taking every fourth or fifth coefficient, and so on, in the binomial deve- lopment; and I asked Sir William R. Hamilton whether he remembered to have seen these theorems stated anywhere. I thought it likely that the well-known elementary theorem respecting the equality of the sums of the alternate coefficients in the binomial development would have sug- gested research in this direction. In a note, written on the day on which he received mine, Sir William stated that my theorem was new to him, and that he had proved it by the help of imaginaries and determinants, The following day he wrote again to me, furnishing me with the fol- lowing more precise statement of my theorem :— ‘‘Let »y and WV be the following (whole) functions of n, y=(—1)", V=4(2"-»); then WV, V and N+» are always the value of the three sums, if suitably arranged; and the singular sum is 8, oY 8), OF 2, according as , or n+1, or n+ 2 1s a multiple of 3.” > I communicated the following demonstration of my theorem to Sir William, in a letter of the 29th March :— Using the notation employed above, we know that (2 + 1), = 2, -+ Mr, (n aL 1s = Ny 1 + Ny-23 and (7+ 1),—(24+1),1 = — Mrs - Now, puting (spire. mo a a os (en 3 SS ecceet (MH1)pmt (M4 1)-+ (4 amt ene ey (m being any positive integer), we have, from equation (1), gs! — 8 = 8, — 8 p2} and, in the particular case under consideration, viz. m=8, S'g— 8 =S.— 8, 8) — 8/9 = 8, — 8, 8/9 — Sy =S) —- &- Thus it appears that the differences of the quantities 8’o, 8’), &2, are equal in magnitude, but of opposite signs to those of s,, 8, 5; and if we form these differences for successive values of x, they will arrange themselves in a cycle of six. Thus, if ia 299 82 — 8, = Ao, $1 — 8) = Az, 8) — 82 =A), we might form the following Table. n Ao > w a =) -—1 cm) | oF KS 25S FS KF CO fF —1 =a orm Qa PrP CE WH a | - OF - F|§ CO KF KH CO | Combining this result with the well-known theorem— 89 + 8; + S82= Ny +My + Ny + en 8) a, e-8. = we arrive at formule for s,, 8, 8. A couple of days later, I communicated to Sir William Hamilton my statement and proof of the corresponding theorem respecting the four sums obtained by adding every fourth binomial coefficient. The theorem is as follows :— ‘< Writing »=(—1)' where z is any positive integer, If n is of the form 42, n-2 So a Qn-2 +y 22 ; $= eae n-2 s— On-a say 2 ‘ S= Dn-2 : If n is of the form 47 + 1, = Gia ees awe oy n-3 Sy On-2 __y 9 Q ‘ n-3 s,= 2"™7- 72 3 300 If n is of the form 47 + i = 23, -2 Se ey o2 = -2 a EE n-2 83 = QPP —y pide If 7 is of the form 42 + 3, Se ae yn 9 Reais ae A AO n-3 8 = 224+ 22, n-3 Sea eye The proof of this rests upon the equations Ba Cee a Sn — 8/1 = 8 — 8, So 8 = oy = Oe a = combined with s, + 8; + 8 + 83+ 2”. Though the theorems which I have now stated or indicated are not — devoid of interest, I should hardly have brought them under the notice ~ of the Academy if they had not led Sir William R. Hamilton to discuss — the more general question treated ofin the Note appended to this paper. — It is at his suggestion that I have communicated the substance of the letter which I addressed to him on this subject. I may be allowed to add, that the first theorem stated in this paper — was suggested by the investigation of a very simple geometrical problem, — and that I have found that it admits of being very curiously illustrated — by means of my theory of algebraic triplets.

Norwirustanpine the great beauty and importance of the investiga- tions of the illustrious Gauss, contained in his Disquisitiones Generales circa Superficies Curvas, a Memoir which was communicated to the Royal — Society of Gottingen in October, 1827, and was printed in Tom. vi. of 303 the Commentationes Recentiores, but of which a’ Latin reprint has been since very judiciously given, near the beginning of the Second Part (Deuxiéme Partie, Paris, 1850) of Liovvitin’s Hdition* of Monex, it still appears that there is room for some not useless Additions to the Theory of Lines and Radi of Curvature, for any given Curved Surface, when treated by what Gauss calls the Second Method of discussing the General Properties of Surfaces. In fact, the Method here alluded to, and which consists chiefly in treating the three co-ordinates of the sur- face as being so many functions of two independent variables, does not seem to have been used at all by Gauss, for the determination of the Directions of the Lines of Curvature; and as regards the Radi of Cur- vature of the Normal Sections which touch those Lines of Curvature, he appears to have employed the Method, only for the Product, and not also- for the Sum, of the Reciprocals, of those Two Radi. 2. As regards the notations, let x, y, 2 be the rectangular co-ordi- nates of a point Pp upon a surface (S), considered as three functions of two independent variables, ¢ and wu; and let the 15 partial derivatives, or 15 partial differential coefficients, of x, y, 2 taken with respect to ¢ and w, be given by the nine differential expressions. du=a/dt+u,du; dx’ =x"dt+u2/du; dx,=x/dt+x,,du; (a).. § dy=y'dt+y du; dy’=ydt+y/du; dy,=y/dt+y,du; dz=2/dt+2,du; dz’ =z2"dt+2/du; dz,=32/dt+2,,du. 3.

In fact, by elimination of R, these equations (m) conduct toa — quadratic in v, of which the roots may be denoted by v,'and v,, which first presents itself under the form, (n).. (e+ ev) (# + B) =(e 4+ ev) (B+ £*), but may easily be thus transformed, (0) Av? — Bv + C=0, or Adu? — Bdtdu+ Cd = 0, “(with A=¢ kh” —-eH, B=avH- ch’, C=ck" — ee so that we have the following general relation, (p)..ceA+eB+e’C=0, (of which we shall shortly see the geometrical signification ), between — 4 the coefficients, A, B, C, of the joint differential equation of the system of — the two Lines of Curvatare on the surface. q 6. The root v, of the quadratic (0) determines the direction of what may be called the First Line of Curvature, through the point Pp of that surface; and the First Radius of Curvature, for the same point P, or the — radius F, of curvature of the normal section of the surface which touches — that first line, may be obtained from erther of the two equations (m), as the value of & which corresponds in that equation to the value v, of v. And in like manner, the Second Radius of Curvature of the same surface at the same point has the value &,, which answers to the value v, of v, — in each of the same two Eyuations of Curvature (m). Wesee, then, © that this name for those two equations is justified by observing that when _ the two independent variables ¢ and w are given or known; and there- ~ fore also the seven functions of them, above denoted by ¢, e’, e’, H, E’, EL”, and &. The equations (m) are satisfied by two (but only two) systems of values, %4, Ry, and v,, R,, of (1.) the differential quotient v, or P which determines the direction of a line of curvature on the surface; — and (II.) the symbol &, which determines (comp. No. 4) at once the — ek and the direction, of the radius of curvature corresponding to that — me. ro a eee > v= - cd 305 7.

But this condition (z) had already occurred in No. 5, as an equation (p) which is satisfied generally by the Lines of Curvature ; we see therefore anew, by this analysis, that those dines on any surface are in general (as is indeed well known) orthogona/ to each other. 9. Finally, asa Ziird General Verification, we may assume x and y (y).. fan H= tan (f,-f) = themselves (instead of ¢ and w), as the two independent variables of the problem, and then, if we use Monge’s Notation of p, g, r, 8, t, we shall easily recover all his leading results respecting Curvatures of Surfaces, but by-transformations on which we cannot here delay. 306 The following donations were presented :—From 1.

Coarztes Graves, D. D., President, inthe Chair. The President delivered the following Address on the loss sustained by the Academy in the death of Sir W. R. Hamilton. ADDRESS. GentTLEMEN,—The death of Sir Wittiam Rowan Hamitton, Andrews’ Professor of Astronomy, Astronomer Royal of Ireland, for thirty-eight years a most distinguished member of the Royal Trish Academy, and formerly its President, was an event which could not be allowed to pass without public notice in this place. There was not one of his brother Academicians who did not look up to him with reverence on the ground of his wonderful genius, the vastness of his attainments, and the number and importance of his discoveries. And there were amongst us not a few bound to him by ties of an intimate friendship, who had watched his brilliant career with an affectionate sympathy, and rejoiced as each new conquest which he achieved in the fields of Science earned for him fresh laurels and a more extended fame. It is not strange, therefore, that his recent death should be lamented by all of us as a loss almost irreparable to Science, whilst within the circle of his friends it is deplored with a profound and lasting sorrow. ‘These feelings demanded utterance. I should have been unfaithful in the performance of my duty as Pre- sident—I should have been untrue to the convictions of my understand. ing and my heart—-if I had not endeavoured to express them. If the expression be inadequate, I trust you will make allowance for the short- comings of a speaker overpowered at once by the greatness of his theme, and by the consciousness of his inability to do justice to it. It is not my intention here to present to you even a biographical sketch of Hamitron or a complete outline of his character. Merely to enumerate his works, and to state with adequate fulness their subjects, would demand more time than is at our disposal. It must suffice if I bring before you the turning points in the history of his life, and briefly recall to your recollection his principal achievements as a Mathematician. Born in August, 1805, in the house of his father, Mr. Archibald Hamilton, in ‘Dominick-street, Dublin, he gave from his infancy indications of the possession of extraordinary powers; and they were not left without wise and diligent culture. His father con- signed him when less than three years old to the care of his uncle, the Rey. James Hamilton, of Trim, formerly a member of this Academy, _and a contributor to its ‘‘Transactions.’’ Under the tuition of this affec- _tionate and able instructor he carried on his studies till he became an ‘undergraduate in Trinity College in 1823. His career there was a _most brilliant one. In every kind of trial he distanced his competitors, and justified all the expectations of his friends. But, whilst thus en- gaged in collegiate exercises of a comparatively elementary nature, he was already entering upon studies of greater range and elevation. A year before he entered College he had drawn up, and communicated to | Dr. Brinkley, then President of this Academy, a paper on Caustics, 308 which was the germ of that ‘“‘Theory of Systems of Rays,” the publi- 7 cation of which first rendered Hamiurton’s name celebrated amongst mathematicians. Brinkley encouraged the youthful author by his kind- ness, and guided him by his counsel. He communicated the paper on Caustics to the Academy, before which it was read in December, 1824, and referred to a Committee, consisting of Dr. Mac Donnell, Mr. Harte, _ and Dr. Lardner. Their report bore testimony to the novelty and — value of the results, and the analytic skill displayed in the conduct of the investigations ; but recommended the author to give a fuller deve- lopment to the processes and reasonings by which his formule and con- clusions were arrived at. Acting on this advice, he employed himself in the intervals of collegiate study in recasting and enlarging his paper, which was anew presented to the Academy, under the title of ‘‘ Theory of Systems of Rays,” on the 23rd of April, 1827. This memoir wasin ~ itself of the highest interest and value; so comprehensive in itsmethod as to extend unlimitedly, and with universal success, over the whole © field of optics. Italso contained the germs of thought which developed themselves in works which afterwards gained for Hamttton the highest distinction. Its table of contents announced an intention of publishing in the third part of the essay an application to dynamics of the same ~ general principle, of which the application to optics was thus in part made public; and its third supplement contains the announcement of Hamitton’s remarkable discovery of Conical Refraction. E. The Professorship of Astronomy in Trinity College became vacant ~ in the year 1827, on the promotion of Dr. Brinkley to the Bishopric © of Cloyne. Perhaps there was no incident in the life of Hamimroy ~ more remarkable than his selection at that time to fill Brinkley’s place. — An undergraduate of one-and-twenty, he was preferred to rival candi- — dates of high qualifications and influence, and the decision of the Uni- © versity authorities in making the appointment was ratified by the © judgment of the public. It seemed to be self-evident that a man who had 7 given such proofs of the possession of a transcendant power in dealing ~ with the most abstract questions in mathematical physics must be the © worthy and rightful successor of Brinkley. As Professor of Astronomy, © two spheres of exertion belonged to him—that of lecturer upon the © science, and that connected with the practical working of the Observa- tory. Those who, have attended his lectures can bear witness to their © merit. ‘They were full of practical teaching, and calculated by their © eloquence to excite in their hearers an enthusiasm for the study which ~ they were intended to illustrate. For the business of the Observatory, 7 it must be admitted that Haumr~ton was not equally well fitted. The™ bias of his genius was undoubtedly to pure mathematics; but, if we estimate the total amount and value of the work which he has done— the impulse which he has given to the whole of mathematical science © —we shall see little reason to find fault with that decision by which he © was placed in the professorial chair, and sustained in the possession of it. | . It was in 1834 that Hamruron received the Cunningham Medal of — this Academy, and the Royal Medal of the Royal Society, as the reward i 309 of his discovery of Conical Refraction. Thisis admitted to have been one of the most remarkable scientific predictions that was ever made—one which announced, on the foundation of pure mathematical calculation, a physical phenomenon which was suggested by no analogy, and seemed beyond the boundaries of probability ; but which, as you know, was completely verified by the experiments of Professor Humphrey Lloyd. In1837 Hamitron was elected President of this Academy, on the death of Dr. Bartholomew Lloyd, who had occupied the chair for the two years succeeding the death of Brinkley. His inaugural address gave evidence of his power to direct the operations of a learned society constituted as ours is. He showed that he entered into the working of all its depart- ments, and could sympathize with the labours of all its members. For eight years, during which he held this office, he exerted himself in every way to increase the usefulness of the Academy, and to sustain its honour ; and, when he resigned the Presidentship, he received the cordial thanks of the Academicians ‘‘ for his high and impartial bearing in the chair, and for his untiring efforts to advance the interests of the body.” We have already mentioned Hamrtton’s paper on a “‘ General Method in Dynamics.”’ In this memoir, starting from the idea of a characte- ristic function, analogous to that employed in his essay on Systems of © Rays, he succeeded in giving a system of complete and rigorous inte- grals of the celebrated differential equations of motion of a system of bodies. This achievement gained for him the Medal of the Royal So- ciety, and the recognition of the greatest European mathematicians. The next great work of Hamrtton of which we have to make mention, is his paper on ‘‘ Algebra considered as the Science of pure Time,” a treatise of a peculiar and semi-metaphysical kind. His object in the composition of it was to establish the foundations of algebra as a science, rather than to improve its processes as an art, or to perfect its symbol- ism asa language. With this was connected his theory of conjugate functions, or algebraic couples, to which he was conducted in his attempts to explain some remarkable results stated by my brother, Mr. John Graves, in a paper upon imaginary logarithms. We now, in this rapid summary, pass on to his last great invention—that of the Calculus of Quaternions. Its elaboration has occupied the last twenty-two years of his life. During that time he has employed this new and powerful organon in discussing questions in almost every branch of mathematics. Most of his attention has, no doubt, been given to geometrical appli- cations. But he has not failed to record in our ‘‘ Proceedings’ results of researches, showing that the new calculus adapts itself to the require- ments of physical science. He has shown how perfectly it enables us to conceive and express, in its peculiar language, the mathematical problem of determining the orbits and perturbations of bodies governed in their motions by the Newtonian law of force. He has also shown that quaternion equations may be advantageously employed in the dis- cussion of Fresnel’s wave surface. I have not attempted to make a complete catalogue even of all his most important works; I have said nothing of his papers on Fluctuating R. I. A. PROC.—VOL. IX. 27 old Functions; on the Calculus of Probabilities ; on the Calculus of Princi- pal Relations; on the Argument of Abel to prove the Insolubility of Equations of the Fifth Degree; on Differences of Zero; on Geometrical Nets in Space. Any one of these memoirs would have been sufficient to make the reputation of a mathematician. Hamitton was gifted with a rare combination of those qualities which are essential instruments of discovery. He had that fine percep- tion of analogy by which the investigator is guided in his passage from the known to the unknown. ‘This is an instrument by which many important mathematical discoveries have been effected. Sometimes the mathematician devises some happy modification in the statement ofa theorem or a method, by which its application may be extended. Sometimes, by analy zing different demonstrations, he even sees that a particular proposition may be made the starting point from which he ascends to more than one generalization. In the investigations of Ha- MILTON we find abundant instances of the skilful use of all the ordinary expedients and instruments of inventive sagacity. But he seems, also, to have possessed a higher power of divination—an intuitive perception that new truths lay in a particular direction, and that patient and sys- tematic search, carried on within definite limits, must certainly be rewarded by the discovery of a path leading into regions hitherto unexplored. Something like this was the unshaken assurance which led Columbus to turn his back upon Europe, to launch upon the broad. Atlantic, and seek a New World in the far-off West. And our illustrious countryman’s diligence in research was not less admirable than his prescient sagacity. No amount of labour to be in- ; curred could deter him from entering upon the calculations by which ~ the correctness of his conjectures was to be tested. The confident expectation of obtaining results instructive in one way or another re- conciled him to the irksomeness of the most tedious and complicated calculations. He felt that the great object to be sought, in the first © instance, was the discovery of the result itself; and he trusted that, once it was reached, he would be able to strike out some more direct and more elegant method of investigation. His MSS., even his pub- ~ lished researches, furnish many examples of this. Once he had reached ~ the conclusion at which he had been aiming, he resumed the considera- tion of the principal steps in his argument; he interpreted them with ~ care; he traced their connexion, and seldom failed to arrive at simpli- fications and generalizations, which amply compensated for the labour spent upon his first essays. By this habit of grappling courageously — with the difficulties of calculation he was distinguished from some ~ other eminent mathematicians. Averse to plunge into depths of cal- — culation from which they see no certain hope of emerging in the end, | they are tempted to expend an undue amount of intellectual energy in © the endeavour to force their way by a direct method to the desired — result. 5m Whilst touching on this point, I cannot help reverting to ano- — ther mathematician of whom Ireland is justly proud—the late Pro- oll fessor Mac Cullagh. I have seen him sit for hours with his paper before him, and all the outline of an elaborate investigation placed upon it. All the while he never took up his pen to execute the work which he had planned. He continued to brood over his task, and scanned it on every side, in the hope of being able to avoid the neces- sity of going through some ‘‘ sea of trouble,’ in the shape of length- ened analytical computations. His taste in mathematics was refined— almost fastidious; and he could not bring himself to look with approval upon any demonstration which appeared wanting in symmetry and ele- gance. JImust not be understood as in the least depreciating Mac Cul- lagh’s power and skill in calculation. His researches in physical optics prove that he possessed these qualities in the highest degree. I only state the fact, that he sometimes was tempted to subject his faculty of mathematical insight to a painful and dangerous strain, in order to avoid the irksomeness of labour that was little more than mechanical. In the case of Hamitton, it is, moreover, deserving of notice, that he evinced a readiness to grapple with the difficulties of calculation, even where there was no prospect of his labour being rewarded by any dis- covery. He engaged in exercises of this kind sometimes from a wish to strengthen his intellectual hold of general propositions by scrutiniz- ing the results obtained, by applying them in a number of particular instances; and sometimes, perhaps, from a wish to mature and keep in exercise those powers of calculation upon the exactitude and prompt operation of which so much depends in the conduct of difficult mathema- tical investigations. I have known him spend hours, or even days, in working numerical examples of some theorem in pure or applied ma- thematics, or in testing the accuracy of some formula of approximation. Occasionally he engaged im tasks of this nature, in the kindly endea- vour to convince some half-crazed squarer of the circle that his pro- posed construction was inaccurate. Finding almost always that it was hopeless to convince the mathematical fanatic of the unsoundness of any of his premises, he would take pains to show him that the results he ob- tained were false in particular instances. And this leads me to notice a feature in his character which deserves to be recorded. From the lofty height of his genius and learning he was accustomed to stoop with the utmost readiness to hold inteilectual converse with inferior minds. Many of his visitors at the Observatory, and the members of the class who attended his lectures in Trinity College, can recall instances of his patience and good nature in answering their questions, and clearing up the difficulties which beset . them in their elementary studies of mathematics and natural phi- losophy. It is remarkable that, while he possessed such powers of calculation, and was almost prodigal in the exercise of them, he was to the last degree solicitous about the metaphysics of every subject on which he undertook to write. We have seen a decisive instance of this tendency of his mind in his treatment of algebra considered as the science of pure 312 time. So, again, in laying the foundation of his Calculus of Quater- nions, we see him labouring to secure its stability by the most careful regard to the primary conceptions. of time and space. Students of his lectures on Quaternions have sometimes complained that he has claimed from them too much attention to the metaphysics of the subject, and has stopped them in their career of building up, in order that they might contemplate afresh the plan of the structure. But this was in accordance with his views regarding the ascending scale of the subjects of human thought. To religion he gave the highest place, and this not as a formality; for his was a deeply reverential spirit. He assigned the next to metaphysics. To them he subordinated mathematics and poetry, and assigned the lowest place to physics and general literature. His studies in the department of metaphysics were extensive. After a thoughtful examination of Berkeley’s writings, he professed himself a disciple of that philosopher, ‘‘ with most cordial and delighted submis- sion;’’ not, indeed, assenting to every separate argument, but embracing his grand results; and in this attachment to Berkeley’s theory we have reason to know that he was confirmed by his converse with Faraday, who, in his own region of investigation, had been led to the conclusion that forces, rather than material particles, were the ultimate objects of physical inquiry. His acquaintance with the German language enabled him to master the works of Kant. Inthe reasonings ofthat philosopher — he was the more ready to concur, as his own previous inquiries had — already conducted him to several of Kant’s views respecting -the in- tuitions of time and space. The literary attainments of ayer were ofa high order. Atan ~ early period of his life he gave surprising proofs of his power in ac- — quiring languages; and though in after years he made but little display of these acquisitions, there can be no doubs but that his familiar — acquaintance with the great Classic writers, and the ease with which ~ he could read works written in the Continental languages, contributed ~ to the culture of his taste and the force of his imagination, as well as ~ to the facility with which he prosecuted studies of a professional kind. ~ In the literary part of his Collegiate course he was not less eminent than in his scientific studies. He was a successful competitor on two occasions for the Vice-Chancellor’s Prizes, proposed for the authors — of English poems; and his examiners placed on record a judgment ~ indicating their sense of his extraordinary proficiency in the Greek ~ language, as well as a similar attestation of his remarkable at- — tainments, for an undergraduate, in astronomical science. He conti- — nued all through his life the devotion to literature of which he © gave these early proofs. He read widely, with an intense enjoy- ~ ment of all that was excellent, and with the discrimination of a prac- — tised critic. With many of the distinguished authors of his time he ~ was on terms of friendship: Miss Edgeworth, Mrs. Hemans, Words- ~ worth, Southey, and Coleridge were his friends and correspondents. 4 With such tastes and associations, it was not to be wondered at if he, — from time to time, gave vent to his poetic feelings in verse. These — 313 compositions were not mere prolusions—exercises in versification—the promptings of a vain desire to excel in walks different from those in which his chief distinctions had been gained. They were the genuine outpourings of a noble heart and fervid imagination, characterized by a depth of thought and elevation of sentiment which compensated for occasional defects in artistic execution. These poetic efforts have an additional interest, as exemplifying in his own productions the con- nexion which he so strongly insisted on as existing between the highest provinces of science and the region of poetry—in both of which he maintained that there was scope and demand for the exercise of the imaginative faculty. According to him, the modern geometry, which deals with the infinites and imaginaries of space, has its beauty and its fascination; and he reckoned the happy daring of such geometers as Poncelet and Chasles as closely allied to poetry. We happen to know that this view of his, as communicated by him to the poet Wordsworth, was to the latter an entirely new revelation, and had the effect of raising his conception, which had before been unduly depreciatory, of the dignity both of science itself, and of its most eminent votaries. Literary and scientific men are often censured, and not without reason, for their want of capacity in the transaction of business. ‘T'o this reproach Hamintron was not liable. He had a retentive me- mory, which enabled him to keep himself familiar with matters of detail; and a love of method, which manifested itself in systematic arrangement of any work which he had to perform. I believe that there never was a President oi this Academy who had such a minute acquaintance with its affairs—such an exact knowledge of its history and constitution ; and, consequently, whenever questions arose respect- ing its laws and usages, he was generally able to solve them by an immediate reference either to established rules, or to the Minutes re- cording the acts of the Academy or its Council. Nor was he less re- markable for qualities as necessary in the post he occupied, and of greater moral worth—for graciousness, combined with truthfulness, for a perfect freedom from all unworthy jealousy, and for a just sense of the dignity of the body over which he was called to preside. Of his efficiency in the transaction of public business he gave signal proof at the time of the first Meeting of the British Association of Science in Dublin. He took an active part, along with Dr. Lloyd and afew other distinguished men of science, in those preliminary move- ments by-which the governing bodies of Trinity College and the Academy were induced to invite the British Association to hold its meeting in this city in the year 1835. On that occasion, being appointed one of the Secretaries for the year, he discharged the duties of his office with a zeal and efficiency which procured for him the cordial thanks of all who took part in the proceedings. It thus fell to his lot to prepare the Annual Address usually read at the first general meeting of the Associa- tion. In that Address, though it was delivered thirty years ago, many of you will remember with what eloquence he expounded the working of the social spirit in promoting the progress of science. He explained 314 to the thousands who listened to him the means, the instruments, the processes which are contained in the operation of that spirit. He told them the men of science assembled there met and spoke and felt toge- ther then, that they might afterwards better think and act and feel alone. He told them that it is indeed the individual man who inves- tigates and discovers—not any aggregate or mass of men; but, recog- nising in the fullest manner the necessity for individual exertion, and the ultimate connexion of every human act and human thought with the personal being of man, he forcibly reminded his hearers that the social feelings make up a large and powerful part of that complex and multiform being. ‘‘ The affections,” he said, ‘‘ act upon the intellect; the heart, upon the head. In the very silence and solitude of its medi- tations, still genius is essentially sympathetic—is sensitive to influence from without, and fain would spread itself abroad, and embrace the whole circle of humanity.”’ And then he proceeded to descant upon the influence which the love of fame exerts in quickening the efforts and cheering the labours of the greatest intellects. The passage is worthy of being referred to for its eloquence alone. But it has for us a special value ; because it reveals to us something of the inmost mind of Hamitron himself, and accounts for traits in his character which were not understood or viewed as indulgently as they ought to have been. A mathematician endowed with such original powers as HamMILton possessed might have been excused, if, yielding to the natural tempta- tion of waiting for casual inspirations, he had carried on his labours in a desultory or unsystematic manner. To such temptations—and no doubt he felt them— he rose superior. He was, on the contrary, re- markable for the diligence and method with which he performed all his work. These qualities are evidenced by the number, magnitude, and importance of his published works. There was no minute care, even in matters of typographical nicety, which he disdained to ex- pend upon them. And in his MS. books, carefully written, and with dates marking from day to day the progress of his scientific life, he re- corded all his meditations, all the calculations through which he passed in his apparently fruitless, as well as in his most successful, researches. These volumes, many of them very large, and numbering about sixty, have been deposited in the Library of Trinity College. They willsupply — to future historians of science the most precious materials illustrating — the development of Hamrtron’s discoveries. They will exhibit, doubt- — less, germs of thought suggestive to others of new discoveries. They — record a great commercium epistolicum—his correspondence with the most distinguished scientific men of his own age. Nay, more, they will be found to contain memoirs on a variety of subjects, complete in them- selves, and carefully elaborated, but which he had abstained from pub- lishing, either because they were unconnected with the greater works ~ which he had in hand, or because he hoped to develope them more fully ~ at some future time. It is to be hoped that they will yet see the light. and, like the posthumous memoirs of Euler, inspire us with a feeling that d15 their great author is still holding converse with us. It will be a satis- faction to the members of this Academy to be told that his “‘ Elements of Quaternions’’—the work upon which he was engaged with the most unceasing activity for the last two years—is all but complete. I have reason to know that at no period of his life—not even when he was in the prime of health and youthful vigour—did he apply himself to his mathematical labours with more devoted diligence. Those who did not actually know how he was employed, or who had formed a false estimate of his character, might imagine him indolently reposing upon his laurels, or pursuing his studies in a desultory way. Such a conception of him would be the very opposite to the true one. His diligence of late was even excessive—interfering with his sleep, his meals, his exercise, his social enjoyments. It was, I believe, fatally injurious to his health. Believe me, Gentlemen, the fame of Sir Wi111am Rowan Haumitron, great as-it was during his lifetime, will become yet greater when ° the world has been furnished with materials enabling it more perfectly to estimate the variety and richness of his endowments and the value of the services which he has rendered to Science. His reputation, even now, does not rest on the partiality of friends and countrymen. ‘The learned men of all lands have already declared him worthy of the highest honours which can be paid to intellectual eminence. This world-wide recognition, at the present time, of his genius and discove- ries, affords us a sure pledge and earnest of the perpetuity of his repu- tation, and warrants us in regarding his name as a glory which is not to pass away from the scientific and literary chaplet of Ireland. And in this fact and this anticipation we might thankfully and happily behold a full justification of his own early, and it might have been teared enthu- siastic, aspirations—of his deep and generous consciousness that he was intrusted with faculties and powers capable of achieving in the noblest fields of thought a worthy tame both for himself and tor his country. What were his feelings on this high subject of conscious power in con- nexion with fame his Sonnet on Shakspeare beautifully expresses; and I cannot better conclude my sincere but inadequate tribute to his memory than by repeating those moving and characteristic lines :— ‘‘ Who says that Shakspeare did not know his lot, But deem’d that in time’s manifold decay His memory should die and pass away, And that within the shrine of human thought To him no altar should be reared? O hush! O veil thyself awhile in solemn awe! Nor dream that all man’s mighty spirit-law Thou know’st ; how all the hidden fountains gush Of the soul’s silent prophesying power. For as deep Love, ’mid all its wayward pain, Cannot believe but it is loved again, Even so, strong Genius, with its ample dower Of a world-grasping love, from that deep feeling Wins of its own wide sway the clear revealing.” I cannot doubt, Gentlemen, that I have had your sympathy in the ex- 316 _ pression of my regret and admiration for one who was your President —for one who, indeed, as a human being, had his share of human in- firmity, but whose nobly countervailing greatness, both intellectual and moral, was such as every Irishman will long love to dwell upon. It was resolved unanimously, That the Academy deeply deplore the loss sustained by them in the death of Sir Wm. Rowan Hamilton, and return to the President their hearty thanks for the eloquent and touching address delivered to them. 317 MONDAY, DECEMBER 11, 1865. Tae Very Rey. Coartes Graves, D. D., President, in the Chair. Mr. W. H. Hardinge read a paper ‘ On the Irish Transplantation of A. D. 1653-54; and on the Extent, Value, and Distribution of the Lands forfeited in Ireland.”’ Mr. W. Hanpset Grirritus read the following paper :— On Ha=MoDROMOMETERS. Tuere has long been a question among physiologists as to the velocity with which the blood moves in the arteries. Many of them have made ealculations which, had they come from others than men of such repute, would have excited derision; and indeed we can scarcely refrain from smiling when we read that Hales “inferred the velocity of the blood at the commencement of the aorta in man to be at the rate of 735 feet per second.” The celebrated Volkman saw the folly of the deductions drawn from such vague data as these were, and he devised an instrument, which he termed the ‘“‘ Hemodromometer,” the object of which was to measure the velocity of the movement of the blood in the arteries. The results of experiments made with this instrument were, of course, much more reliable than those founded on calculations inferred from data of the most vague and uncertain character; but, while I would unhesitatingly give the preference to the deductions drawn from experiments with Volkman’s Hemodromometer, I can by no means as- sent to the supposition that they are correct, or even nearly so. The use of Volkman’s instrument involves great objections; and, although I look on the instrument itself as a model of ingenuity, I cannot regard it as one on which I should depend for a solution of the problem, With what velocity does the blood move in the arteries? I will proceed to describe as briefly as possible the construction and mechanism of Volkman’s Hemodromometer. I will then consider the objections which I entertain to it; and it is but right that I should afterwards mention how I would propose to rectify these defects. Volkman’s Hemodromometer consists essentially of a glass tube, which is bent into the form of a hairpin, and is fifty-two inches long. This tube is filled with water; and, by a peculiar arrangement, is placed between the open ends of a cut vessel. For a concise de- scription of this instrument, I beg to refer to Todd and Bowman’s “Physiological Anatomy,” vol. ii., page 364. In the drawing which is given in that work is represented a tube, which is constructed of metal, and measures one inch and a half in length; it terminates at cones, which fit into other cones, by which means they are adapted to the cut ends of the vessel. The mechanism of the stopcock is indeed an admirable contrivance; and, although easily understood, R. I. A. PROC.—VOL. IX, 2U 318 is rather difficult of description. The handle commands the course of the tube by means of two cogged wheels, so that when it is turned in one direction it allows a free passage directly from one end to the other; and when it is turned in the opposite direction this free passage is interrupted, and another passage, namely, from one end, along the hairpin tube, to the other end is opened; so that at the will of the operator he can open one communication to the exclusion of the other, but he cannot obtain a double communication. The glass hairpin- shaped tube is attached to a board, on which is fixed a scale. When the Heemodromometer is used, alarge artery is exposed for about three inches, and a piece is cut out of it after means have been adopted for the prevention of hemorrhage. The next step is to fix the cone- shaped open cups into the open ends of the artery, and each end of the horizontal metal tube is then fitted into its corresponding cup. I should mention a precaution which it is here’ necessary to observe—it 1s this : to so arrange the distance of the cups that, when the horizontal tube is introduced between them, the continuation of the vessels is as little altered as possible by the intervening mechanism. The blood now con- tinues to circulate through the horizontal tube as it would were the vessel entire, the stopcock being so turned as to shut off communication with the glass tube. Thislatter is now filled with water, and is fixed to the horizontal tube by means of pipes. The arrangement is now com- plete, and the stopcock is turned, so as to shut off the direct communi- cation between the two ends of the horizontal tube. The blood now enters the glass tube, and pushes the water before it into the peripheral blood vessels, with (according to Volkman) only a very slight admixture between the two fluids. T have now described at length this very ingenious instrument; and it would seem at first that it supplies what is needful, in every respect, and that the results obtainable from experiments with it are very reliable. On mature consideration, however, no one will fail to perceive that there are grave objections to it; and it now devolves upon me to mention those which have struck me as being most prominent. There are one or two of these objections which I myself have not succeeded in obviating; and many will say that it were well that T should pass over these, and confine myself to such as I can re- move. Were I to heed such suggestions, I should not be performing the duty I have taken on myself; for, although the instrument which I am about to describe I believe to have many advantages over that of my brother physiologist, no one is more sensible of the fact than I am that it is by no means a perfect instrument, and that it is itself open to great objections—objections which I do not despair of being able to remove at some future period, or which, I myself being incompetent, will I doubt not be done away with, and that right speedily, throngh the exertions of the learned physicists and physiologists to whose no- tice I submit them. Thus, in mentioning objections to Volkman’s He- modromometer which bafile my own inventive faculties to memove, I -anticipate the defects of my own instrument. MS Pr iebag Sok Eee 319 The first objection which I have to state to Volkman’s Hemodro- mometer is applicable to mine also—it is that of the sudden propulsion of the blood from a tube of elastic and contractile force into one perfectly inelastic, and one not having muscular force. The effect of this condition is more serious than is generally imagined ; for when the natural calibre of the artery, or its caliber when not in the distended state, corresponds with that of the glass tube, the former is capable of receiving a greater quantity of blood than the latter; and the contractility called into action by this expansion is now exerted, and contributes to quicken the velocity of the remaining fluid. No such conditions as these exist in the glass tubing; and the only plan I have adopted, with a view to lessen this difference between the two tubes, is to use a glass tube whose ca- liber will be equal to that of the artery when at a moderate expansion. The second objection is one which, although I have considerably lightened, I have not been able entirely to meet, namely, the existence of sharp turns in the long glass index tube. In Volkman’s instrument there are three of these sharp turns; one at the entrance, and another at the exit, both of which are right-angled ; the third is situated in the centre of the tube, and is in reality made up of two turns, each of which is right- angled also; the effect is alleviated in the latter case by the curves being well directed ; but in the former cases, namely, at entrance and exit, the arrangement is directly angular. I need not say how detrimental to the velocity of a running fluid the presence of these angles is, nor need I explain how the column of blood which is being propelled into the tube, meeting at its entrance an opposing wall has to be reflected, as it were, from it before it pursues its course. The same takes place at the exit of the tube, except that here the reflection, if I may be allowed the term, takes place in an opposite direction ; so that, instead of the fluid being prevented to a degree from entering the tube, it is here hin- dered in leaving it—not altogether, of course, but in a degree to affect considerably the velocity of the movement of the contained fluid. At the centre of the tube, also, is a sharp turn, arranged so that the fluid arriving by one limb of the tube has to be sent back immediately after moving round this sharp double turn in the opposite direction. My instrument must be regarded as of much better design in respect to curves in the tube than that of Volkman; for, while the fluid entering into his 1s immediately sent in a direction at right angles to the course, the direct course of mine is interrupted but very little. The curves in my Hzemodrometer are greatly exaggerated, and the caliber of the tube where they exist is slightly increased. The third objection which I would urge is the sudden propulsion of hot blood from a vessel of a certain temperature into another of a much lower degree of heat, or almost cold. ‘This defect would seem to be of such trivial consequence as to warrant its being entirely overlooked. _ The experiments which I have made touching this question, however, induce me to insist on the above as a decided objection. I have seen that when blood or any other fiuid is heated to a certain point, and is passed through a vessel of a certain temperature, and when, after 320 traversing this tube for a certain distance, it is then made to pass through another tube continuous with the first, but cooled to or below zero, the velocity of the running fluid is diminished from that which was maintained in the heated tube. The manner in which I have sought to remedy this evil is the following :—The flat support, to which is attached the essential part of the instrument, is made so as to contain two moveable iron heaters; when these are removed, and heated, and then sent home into their respective cavities, the warmth they contain is communicated first to the copper support, and thence to the glass tube, through which the blood courses. The next objection refers rather to the mode of using the Hemodro- mometer than to the instrument itself. Volkman’s apparatus was, you will remember, filled with water previously to operating. Now, no one will refuse to recognise the inadvisability of the blood having to meet a fluid of a very different specific gravity from itself, and one, more- over, whose total immobility it has to overcome ere it can itself move an inch. I look upon this as a most serious objection to Volk- man’s mode of estimating the velocity of movement of fluid in a tube; and indeed Volkman himself would seem to have anticipated that the validity of his method would be called into question on this account, since he takes care to inform us that the water is moved into the peri- pheral arteries with but little admixture with the blood. I can only say that I have put Volkman’s statement to the test of experiment, the most reliable criterion, and I have invariably found the mixture of the two fluids to be most considerable, and the specifie gravity of the re- sulting mixture to vary much from that of either the blood or water. When using my instrument, I apply one end of the tube to the cut end of the artery whenee the blood flows, and I apply suction at the other end, so as to create a vacuum, into which the flood flows freely. When it has arrived at the opposite end, having turned the stopcock, I remove the ligature which had been placed on the peripheral end of the artery, and introduce the end of the tube into that of the vessel; and the blood flows, on again turning the stopcock, as though 1t experienced no in- terruption whatsoever. Of course, these latter operations should be performed as quickly as possible; and, inorder to avoid the trouble of tying and untying ligatures, I make use of a minute forceps—one which on pressing with the fingers opens, and on removing the pressure closes with a tight grip. I have now mentioned the four great objections which I have to Volkman’s Heemodromometer : each one of them tends to decrease the ve- locity of the blood’s movement ; and hence, when we consider the combined effect of these, we must allow that the results of experiments made with this instrument are not such as can be relied upon, nor do they correctly estimate the velocity with which the blood moves in the arterves. It now behoves me to describe a Heemodromometer which I would propose as a substitute for Volkman’s; and I must confess that I feel considerable diffidence in so doing, not because I myself doubt for one instant the superiority of my instrument as far as regards accuracy, but 321 since I feel it to be presumptuous in me to offer aught to the scientific world intended to compete with the productions of so learned a physi- cist and physiologist as Volkman. My duty, however, prompts me not to yield to such feelings; and so, with a firm conviction of its worth, I proceed to the description of my Hemodromometer. In my description I beg to refer to the diagrams, such as they are, which I have drawn, in order to render the details more intelligible. The complete instrument, as seen in the drawing (Fig. 1), consists of the copper support, to which is attached, by means of the fasteners Fig. 1. (a, a,q@), the glass index tube, furnished with its arrangements of stop-cock (6), and piston (c). The free extremities of the glass tube extend slightly beyond the support, so as to be more readily connected with the cut ends of the artery. Near the centre of the support is a chronometer, the hand of which describes the circlein one minute. At one side of the support are represented the heaters (¢), which are sent home into their respective cavities. The shape and construction of the support will be readily seen on glancing at the diagram. It is made of copper, which is a very good conductor of heat. At its side are the openings of the two cavities, which extend longitudinally along it for about three-fourths of its length; into these cavities run the iron heaters, furnished with handles of porce- lain, so as not to burn the hands of the operator when they are to be removed from the fire. The heaters are kept in their position in the support by means of a long iron pin, which runs through a hole in the Support and heaters, as seen in the drawing (/). The index tube will be seen to have a peculiar form; and, simple as this form looks, it has cost me much thought and consideration to de- termine on it as being that which would be least likely to prove detri- mental to the flow of fluid in it. This tube will be observed to have no sudden angles in its course. The fluid on entering into it is not met by an opposing wall, as in Volk- 322 man’s instrument, nor is it immediately turned in a direction at right angles to the one it was previously pursuing ; on the contrary, the de- viation from the natural course is gradual, and the fluid is coaxed, as it were, round the turns in the tube, when it arrives at them. I have already mentioned that the caliber of the tube equals that of the artery when at a moderate expansion, and also that the caliber of the turns of the tube is very slightly wider than the caliber of the straight por- tions. I need not again repeat why these differences in caliber should exist. From the foregoing remarks you have already anticipated the necessity for having different tubes, each with a different bore, so as _to be applicable in the case of variously-sized arteries. JI have de- scribed to you Volkman’s arrangement of cone-shaped cups for connect- ing his tube to the ends of the arteries. I do not recognise the necessity for this plan at all; and I believe that, if the glass tube have its termination furnished with slightly raised edges, so as to take a pur- chase on the artery, the desired effect is obtained just as well. The removal from or fastening of the different tubes to the support is easily effected by opening and shutting the fasteners (Fig. 1 ¢), which are furnished with hinges and clasps. Each tube is fur- nished with a piston index apparatus (c), and with astopcock(6). The piston index ap- paratus (Figs. 2and 3), consists of two tubes, the one horizontal, whose _ bore equals that of the glass tube, and which is continuous with it; the other perpendi- cular, arising from the centre of the for- mer, and into which fits exactly a piston. This latter tube, in- stead of being round- ; ed, as is the horizontal tube, is square. Where the two tubes commu- 1 Mi {ZZZjjjjjjss: nicate, therefore, a square orifice exists in the upper wall of the hori- zontal one (Fig. 4); so that, were fluid tra- versing this latter, it would rush up into == the square perpendi- . cular tube. The handle of the piston consists of the stem, the press, and the handle proper. The stem is of such length, that, when the ‘ piston is shut down, the press, or lower surface of it, must form a Fig. 4. | | 323 continuous surface with the upper wall of the horizontal tube. In order to effect this continuity of surface, the press (Fig. 5) must be curved correspond- ingly to the wall of the horizontal tube; and it must be of such size as exactly to fit the piece which is want- ing where the two tubes, horizontal and perpendicular, communicate. The whole of this mechanism is constructed of brass. The piston must be removable from its perpendicular square tube, so as to admit of the index ball, which I shall presently describe, being attached to its press. When an observation is to be made, the piston is to be taken out, together with the lid of the perpendicular square tube. To the under surface of the press is then attached lightly the index ball, which is made of gelatine. The arrangement is then placed in the position as seen in the drawing (Fig. 2), and the blood is now brought through the glass tube, the above preparations having been, of course, completed first. When the time has come for making the observation, after the blood has been circulating for a few seconds, the piston is pressed down, the spring which kept it raised is overcome, and another spring is engaged which keepsit down. The index ball is thus suddenly propelled into the current, and, being of a certain size, is carried along the tube with the same velocity as that with which the blood itself moves; the lower end of the press of the piston has at the same time formed the wanting part of the upper wall of the horizontal tube, and the blood courses without interruption. The index ball has not gone far before it comes up to a scratch (Fig. 1, 7) on the glass index tube. As it passes this point, the operator glances at the chronometer, and notes the time ; sub- sequently, the ball passes another scratch (Fig. 1,7), which is at a known distance from the former one, and immediately as it does so, the operator again consults the chronometer, notes the time, and turns the stopcock to prevent the ball from passing into the peripheral end of the artery. The observation is now completed, the index ball having passed through a certain distance in a certain lapse of time, and thus the velocity of the movement of the blood has been computed. For a long time I was puzzled how to obtain balls of such lightness as would not affect the movement of the blood. After some consideration, I adopted the following process :—A warm concentrated watery solu- tion of gelatine is made, and the polished extremity of an iron rod is rolled about in it, having been previously dipped in oil. The rolling haying been continued for some seconds, the rod is taken out of the solution, and a thin coating of gelatine adheres to it. This coating has now to be removed from the mould, which is done by very gentle manipulation, until it is coaxed off. A small “ ex- hauster,”’ furnished with a sharp extremity, and with a stopcock, is now introduced into the open mouth of the gelatine ball, and, by working a24 with the fingers, the latter becomes tightly applied to the extremity of the exhauster, and the air is sucked out from the ball by the mouth. When it is considered that nearly all the air has been subtracted, the stopcock is turned before taking the exhauster from the mouth, and while the suction is yet going on; a little careful manipulation is now required to remove the ball from the exhauster without allowing the air to re-enter. When the operator has succeeded thus far in the manu- facture of his ball, the next step is to make it as round as possible. This is effected by two “rounders” (Figs. 6 and 7), which I have sketched; these consist of polished metal; they are hollowed out slightly from centre Figs. 6 and 7. to surface; one of them is furnished with a handle, and the other is to be laid on the table when using them. They are first heated by pouring some warm oil on the polished hollowed surface; the index ball is put on the one which is stationary, and the other ‘rounder’ is gently worked over it in a cir- cular manner until the ball has become per- fectly round; the rounders are heated at in- tervals by adding more hot oil to their polished surfaces. I need not mention the necessity there is for iron moulds of different bulk, in order to produce balls of different sizes, adapted to the variously sized tubes. IT have now completed the description of my Hemodromometer. That I do not expect it to be considered as anything like a perfect in- strument, I have already said. I know that some physiologists will object to it on account of the complexity of previous operations which must be performed when working with it; but will any one, I ask, give the preference to Volkman’s instrument simply because of the trouble of working which mine would cost the operator ? If so—if it is desirable that instruments be made with a view rather to save the operator work, than to attain to accuracy of result—then have I laboured in vain.

The PresrpeEnt delivered the following ApprzEss on the loss sustained by Archeological Science in the Death of Grorcr Petriz, LL. D. :— ADDRESS. GENTLEMEN,—Only a few weeks have passed since I was called on to express our sense of the loss sustained by the Academy—by Science it- self—in the death of Sir William Rowan Hamilton. If any one of us had been asked, a year ago, to enumerate the great men of our own country and our own time, he would have been almost sure to give pre- cedence to the name of Hamilton. And now, whilst our mourning for him is recent, before we have accustomed ourselves to the thought that he is no longer a fellow-labourer with us, that he has gone to his rest, and that the works which he has left unfinished must be carried on by other hands, death has made a fresh inroad on our ranks, and robbed us of all the pleasure and the pride which we felt in companionship with one who, in the department of antiquarian and historic literature, had at- tained a pre-eminence as decided as that which Hamilton had won for himself in the pursuits of mathematical science. It is hardly possible to exaggerate the gloom which the death of Grorcr Prrriz has cast over the friends of literature in Ireland; for his name had become a household word amongst us. His genius and learning had rendered him famous; and the charm of his noble and graceful character had R. I. A. PROC.—VOL. IX. 2X 326 made him equally beloved. Thus he had grown to be a power—the centre of a great sphere of intellectual activity ; and we could not con- ceal from ourselves the obvious fact, that his removal from the field of his labour is a source of peculiarly anxious concern. The death of a great mathematician like Hamilton is with reason lamented, because it certainly retards the development of those branches of mathematics in the cultivation of which he had been most successful; but it can hardly be thought of as absolutely irreparable to science. The band of whom one of the leaders has fallen is a numerous one. It gathers its recruits from all parts of the civilized world. It extends its conquests with a march certain, though not uniform, into the regions of the unknown. Scientific progress in any particular di- rection suggests research, and facilitates further progress. Thus science advances like a tide, pressing onward with an accumulating force. If Newton and Leibnitz had died before they had made their famous dis- coveries, we can hardly doubt but that other scholars in these king- doms, in France, in Italy, in Germany, or in Russia, would have created the Differential Calculus, and furnished us with an instrument, the need of which was felt in dealing with most of the great problems which at that period engaged the attention of mathematicians. The successful prosecution of the studies to which Prrrizr devoted his life depends on circumstances of a more precarious nature; and we cannot count with the same certainty upon their continuous progress. We cannot expect that many will apply themselves to the history and anti- quities of Ireland; and of those who do, how few are likely to illustrate them by the critical sagacity, the extensive learning, and the sound judgment of the veteran scholar whose loss we are now lamenting ! Let any man picture to himself the condition to which Irish archeology and other kindred studies would have been reduced, if it had not been for the labours and the influence of Petrie during the latter half of his life; he will then understand why Prrrin’s death has been felt as a national calamity. Grorcr Perrier was born in Dublin, on the Ist of January, 1790. He was the son of James Petrie, an eminent portrait and miniature painter, from whom he inherited a taste for both literature and art. His general education was carefully attended to. He was sent to the school of Mr. Whyte, of Grafton-street, who at that time gave instruc- tion to the sons of many of the most distinguished citizens of Dublin; | and there, sitting perhaps at the same desk as that at which Thomas Moore and Richard Brinsley Sheridan had sat before him, he acquired that sound knowledge of the English and of the Classical languages which he afterwards turned to good account, when he became a man of letters. As a boy, he showed a decided preference for art. At an early age he was allowed to assist his father in painting miniatures; and when only fifteen had attained such skill in drawing as to gain a silver medal for a group of figures in the School of the Dublin Society. Oc- cupations of this kind being more to his taste than the studies and as- sociations connected with the profession of surgery, for which his father in fb Sete RPT ag EES ple tei aie al ea ae re ar A a tied 2 Pa fe. 327 designed him, he was permitted to follow the bent of his genius, and for several years devoted himself to landscape painting. This is not the occasion on which a full account of his labours as an artist would be appropriate; but I may be allowed to say, that they were varied and successful. His pencil was for many years put in re- quisition by those who sought for the most perfect illustrations of Irish scenery and topography. His drawings were engraved by the most ce- lebrated engravers. The pictures exhibited by him in London and in this city attracted the admiration of the most accomplished art critics. I have some idea of the causes of his success. I believe that it was due, in the first instance, to the truthfulness with which he represented the grace and harmony of the lines traced by Nature herself in the real landscape. He seems to have perfectly appreciated their characteris- tics. He knew that these lines are produced by natural agencies of various kinds working simultaneously—by forces which shape the outline of a mountain, as well as by those which determine the form of a leaf. It was his nice perception—or call it, if you will, an intui- tive feeling—of the proper flow of each separate line, and of its relations to the other lines in the picture, which enabled him to produce draw- ings almost matchless in delicacy and grace. IfI have failed to convey my meaning to any of my hearers, I can promise them that they will at once recognise the excellence of which I have been speaking in the illustrations contributed by Prrriz to Lord Ormond’s “ Autumn in Sicily.” His skill as a draughtsman was transcendent. Critics allege that as a colourist he was less successful. It is not given to the same man to excel in every branch of his art. Still it must be said of him that he showed a fine perception of harmony and balance of colour, even though we may admit that he was sometimes deficient in force. But the artist who could paint such pictures as his ‘‘ Pass of Llan- beris,” his ‘‘ Walk in Connemara,” his ‘‘ Shruel Bridge,” and ‘‘ The Home of the Herons,”’ has secured for himself a high place in the list of water colour painters. These are works in which the artistic treatment of the subject manifests an intense love of Nature, and a familiar ac- quaintance with the expressions of her ever-changing face. And they possess a higher merit. They are not the products of a merely imitative art. They are poetical in their conception, and full of imaginative power. Praise from one who has so little practical acquaintance with art as I can lay claim to may be nearly valueless; but I believe that, even in the presence of those who have most knowledge on this subject, I should provoke no expression of dissent, if I asserted that Purriz had attained to a very distinguished position as a painter. His brother ar- tists in this country long ago acknowledged his eminence by conferring upon him the honourable office of President of their National Academy ; and artists of the highest repute in England, by their correspondence and their friendship, bore testimony to the respect which they enter- tained for him as a professional compeer. From his schoolboy days Perris took an interest in the monumental remains which fell under his observation in the neighbourhood of 028 Dublin; and as his sketching tours led him afterwards into remote parts of the country, where dismantled castles, and ruined churches, and time-worn crosses, besides furnishing subjects for his pencil, excited his curiosity respecting their history and age, his early predilection for antiquarian pursuits must have been drawn out and fostered. Never- theless, he might perhaps have continued to devote himself exclusively to the practice of his art as a painter, ifaramble in company with some friends through the western counties of Ireland had not brought him, in 1818, face to face with the ruins of the Seven Churches at Clonmac- noise. There, indeed, he saw a group of ecclesiastical remains, inte- resting in their architectural features, and picturesquely placed on the sloping shore of our great western river; and he perpetuated the scene by making it the subject of one of his most exquisitely painted pictures. But these ruins excited a still deeper interest in his mind, regarded as memorials of the men who lived, and the civilization which subsisted on the spot a thousand years before. Looking around him in that great cemetery, he found it filled with inscribed monuments, recording the names of distinguished persons who had been buried there in former times. It was a favourite place of sepulture for kings and chiefs, for bishops and abbots, for men of piety and learning, from the sixth to the twelfth century. Applying himself first to the copying of these inscrip- tions, he made drawings of above three hundred of them. But, as few of them had been previously noticed or explained in any printed work, he was obliged to investigate for himself the history of the per- sons whose names were thus preserved. With a view to the accomplish- ment of this object, he commenced, and from that time continued, the formation of such a collection of documents, whether in manuscript or in print, as he hoped would lead to the illustration of the monuments. Thenceforth, in fact, he became an archeologist, devoting as much time and attention as he could spare from other avocations to the study of Irish history and antiquities. PurTrie was elected a member of this Academy in the year 1828, a year after the name of Hamilton was added to our roll. He was chosen a member of Council in 1830, and at once applied himself, in conjune- tion with other distinguished members, to raise the Academy from that state of torpor in which it had remained for the previous quarter of a century. At that time it could not be said that we possessed a Mu- seum; and a stranger now visiting it, admiring its riches, and profiting by the labours of Sir William Wilde in arranging and cataloguing it, could hardly believe the facts in its history which I am about to men- tion. The King of Denmark had some time previously presented to the Academy a collection of stone implements, of no small value and interest, when placed alongside of and compared with similar objects found in this country. They had, however, been allowed to lie unnoticed and uncared for. Other antiquarian articles, presented to the Academy by various donors, were deposited in the Museum of Trinity College, there being no place fitted for their exhibition in the Academy. Immediately upon his appointment as a member of Council, Perris collected these re- 329 mains, and had them placed for security in an unoccupied glasscase in the board room. These antiquities, as 1 have heard from his own lips, had previously been left exposed for years on the floor of a small apart- ment, called a Library, in the upper storey of the Academy House; and between the period when Prrriz had first seen them in this situation, previously to his election as member of the Academy, and that at which he rescued them from future danger, nearly one half of the articles, and those the most precious, had disappeared. From this epoch dates a pe- riod of fruitful activity in our Committee of Antiquities, happily con- trasting with the inertness of the previous seventeen years, during which its meetings had been absolutely suspended. I should occupy too much of your time, if attempted fully to record the services which Petrie rendered to the Academy, by helping towards the acquisition of the various collections, the assemblage of which in our Museum has given it a national character. It must suffice for me to name the Un- derwood Collection, and those of Dean Dawson, and Major Sirr. It is right to notice that in these various movements PETRIE received the most cordial and efficient support from the late Professor Mac Cullagh, whose sympathies were, no doubt, drawn forth by the manifestation on PErRixz’s part of a truly scientific spirit in his method of dealing with antiquities. Many of you are aware that it was at Perrin’s instance that Mac Cullagh purchased the Cross of Cong, and made that splendid donation to our Museum ; and I may add his generous contribution towards the pur- chase of the Tara Torques as another proof of the same sympathy. In- deed, it may be recorded as one of Putrin’s academical distinctions, that to his personal influence was mainly owing that happy union between the scientific and archeological elements within our body, upon which Wwe may now congratulate ourselves, but to which, before his time, cor- responded a relation of passive, if not active, opposition. Perris contributed no less important services towards the formation of our Library. Whenever opportunities offered of acquiring Irish MSS., he exerted his influence to induce the Academy to supply funds for their purchase. The grant placed at his disposal for this purpose being fre- quently inadequate, he ventured more than once, at his own risk, to secure MSS. the value of which he understood better than any one, and which he knew ought to be added to the Academy’s collection. Thus, at the sale of Edward O’ Reilly’s MSS.., after the Academy’s grant of £50 had been exhausted, he purchased for himself some of The O’Cleary’s MSS., and afterwards gave them up to the Academy at the cost price. Having become under precisely similar circumstances the possessor of the autograph copy of the second part of the ‘‘ Annals of the Four Masters,’’ he generously surrendered it to the Academy for the sum he had given for it, although immediately on its becoming known in the saleroom what the MS. was, he was offered, in the first instance, £100 over and above the purchase money, and was subsequently pressed to name any sum that would induce him to resign it. In acknowledgment of the generosity and zeal evinced on this occasion by Prrriz, the Aca- demy passed a resolution declaring him a Member for Life. 330 Perrig contributed numerous papers to our ‘‘ Transactions” and ‘* Proceedings.’ His first communication was a paper ‘‘ On the Auto- graph Original of the Annals of the Four Masters.’’ This was followed by a description of the Domnach Airgid—an ancient reliquary, contain- ing a copy of the Gospels, which belonged to St. Patrick. I must refrain from stating the titles of his other contributions, with the exception of the three to which this Academy awarded its gold medal. These were —his essay ‘‘ On the Origin and Uses of the Round Towers;”’ his essay “On Military Architecture in Ireland ;”’ and his essay ‘‘ On Tara Hill.” The second in order of these essays remains unpublished. I proceed to notice the contents of the other two. The work which is most closely associated with the name of PETRIE is his celebrated ‘‘ Essay on the Round Towers.’ It was originally written for and presented to the Academy, and was rewarded by your gold medal, and a prize of £50, in 1833. ‘This essay is included in the treatise ‘‘ On the Ecclesiasiastical Architecture of Ireland,’ of which the first portion forms the twentieth volume of our ‘ Transac- tions.” The writer, feeling that the question as to the origin and uses of the towers could not be satisfactorily settled except in connexion with a systematic review of Christian architecture as it existed in Ire- land previous to the Norman invasion, wisely resolved to make his essay the basis on which to erect a more comprehensive work; and that work, intended to be exhaustive and decisive on the subject of which it treats, grew under his hand into proportions very different from those of the original design. References had to be made to authorities of, different times and in different languages—many of the most conclusive being gathered from our Irish MSS., and produced by him for the first time ; although it might have seemed natural that writers, treating of Irish antiquities, would have looked, in the first instance, to our own history and annals for information. In order to furnish adequate means of judging of the structural features of the buildings described, it was also necessary to supply abundant illustrations. In preparing these, the author was independent of the assistance of other draughtsmen. The volume is enriched by numerous drawings, which are almost as interest- ing to the artist as to the antiquary. Again, our fellow-Academician ~ conceived it to be necessary to examine and confute all the opposing theories as to the origin and uses of the towers. This imposed upon him the obligation of showing, as regards their origin, that they were not Danish or Pheenician; and, as respects their uses, that they were not fire temples; that they were not places from which the Druidical festi- vals were proclaimed; that they were not astronomical observatories ; that they were not phallic emblems, or Buddhist temples; and, lastly, to come to supposed Christian uses, that they were not anchorite towers, or penitential prisons. To prove a single negative is prover- bially difficult. Can we complain, then, of Perrre as having been te- dious, if, in the compass of about one hundred and twenty pages, he has temperately and conclusively disposed of so many erroneous theories ? I make bold to say, that he has disposed of them, though there yet re- dal main amongst us—I say it with regret—too many who still cling to their opinions as to the indefinite antiquity and pagan uses of the towers. There is something romantic in the notion of their being monuments be- longing to a rave wholly lost in the mist of antiquity ; and there is some- thing imposing in the parade of Oriental authorities, and the jingle of fanciful etymologies, in which Vallancey and his disciples so freely dealt. But I have never yet met any intelligent man, who has taken the pains to read through and understand Prrrin’s Essay, and who has also gone out of his study and examined Round Towers with his own eyes, and compared their masonry and architectural details with those of the ancient ecclesiastical structures beside which they often stand, who was not ready to give his frank assent to PErrim’s main conclu- sions. 1am speaking of the most remarkable essay that was ever pro- duced by an Irish antiquary. You will, therefore, permit me to remind you what those conclusions were :—I. That the towers are of Christian and ecclesiastical origin, and were erected at various periods between the fifth and thirteenth centuries; Il. That they were designed to an- swer at least a twofold use—namely, to serve as belfries, and as keeps, or places of strength, in which the sacred utensils, books, relics, and other valuables were deposited, and into which the ecclesiastics, to whom they belonged, could retire for security in cases of sudden preda- tory attack; III. That they were probably also used, when occasion required, as beacons and watch towers. If it were possible to over- throw, or seriously to modify, the conclusions at which Perris has ar- rived, this essay would still continue to be a pattern deserving the close imitation of writers undertaking to treat of similar subjects. It is phi- losophic in its method; its style is clear and graceful; without being pedantic, it is copious in references to original authorities; and, what is rare in works of a controversial nature, it is remarkable for the good temper and good taste with which the writer treats the reasonings of his opponents. In 1840, Perris received the gold medal of the Academy for his essay “‘ On the Antiquities of Tara Hill,” printed in the eighteenth vo- lume of our ‘‘ Transactions.” This essay was a portion of the Memoir intended to accompany the Ordnance Survey Map of the county of Meath. Its subject, as the title indicates, is partly antiquarian, and partly historical; and it deserves special notice, because the latter element is developed more perfectly in it than in any other of Perrre’s writings. Having gathered from our most ancient MSS. every notice contained in them of the Hill of Tara—a spot celebrated by foreign as well as native writers as the chief seat of the Irish monarchs, from the earliest dawn of their history down to the middle of the sixth century—he proceeds, in the first instance, to analyze those which record events connected with the civil and ecclesiastical history of Ireland, and then goes on to show the exact agreement of the monuments still remaining with the descriptions of raths and other structures mentioned in ancient topogra- phical poems and tracts as having formerly existed at Tara. The first portion of the paper touches upon several subjects of great interest. = se d02 Such, for instance, is the account of the compilation and promulgation of laws by Cormac Mac Art, in the middle of the third century ; and the compilation, two hundred years later, of the ‘‘Seanchus Mor,” in the time and at the instance of St. Patrick. The hints which he has given in this paper will afford valuable help towards the settlement of some of the most perplexing questions connected with our early Irish history Though we may feel sure that the catalogue of 142 kings who are re- corded as having reigned at Tara prior to its desertion in the year 565 is largely mythical, we should be rash in totally rejecting all the state- ments for which we have no better authority than bardic legends. PETRIE has pointed out the probability of some of these, and adduced confirma- tions of them, derived from independent and trustworthy sources. One of the most curious parts of the “ Essay on Tara’”’ is that in which he discusses the perplexing difficulties which beset the history of St. Pa- trick—I might rather say, of the Saints Patrick, for there were certainly two of the name—and proposes to identify the second St. Patrick with Palladius. The recent investigation of this subject by Dr. Todd has brought its difficulties into a clearer ight ; but the solution of them seems still almost beyond our reach. The second portion of the essay furnishes a striking instance of the use to be made of antiquarian research in esta- blishing the authenticity of documents. The ‘‘ Dinn Seanchus,” a well-known topographical work of great antiquity, contains tracts and poems relating to Tara, some of which describe with considerable mi- nuteness the buildings which formerly stood there. With the buildings so described Perriz was able with complete certainty to identify the erumbling remains which are still apparent. Such a confirmation of the accuracy of the accounts disposes us to attach more credence than we should otherwise have given to statements respecting the uses to which the various structures were applied, and all the details respecting the mode of life of their ancient occupants. The truth of these very ancient testimonies being corroborated in certain points, the probability of their being in the main trustworthy is increased in a high degree. The circumstance which must be considered the most important in Perriz’s life as giving definiteness to his labours and completely deve- loping his powers, was his connexion, in the year 1833, with the Ordnance Survey of Ireland. The occasion for his services in this de- partment arose in the following manner :—In the construction of the maps, it was a matter of primary necessity to determine the orthography of the names of places; but it also proved to be a matter of extreme difficulty. Various modes of spelling them were found to be sanctioned by common usage. Reference, therefore, had to be made to documents of all kinds; and an inquiry, involving comparison between the existing and the ancient states of the country, had to be instituted; in fact, questions relating to the spelling of the name ofa townland or a parish frequently gave rise to elaborate researches, which were not disposed of till it had been ascertained that the name was indicative of some early sept, some ecclesiastical establishment, or ancient chief. Thus the co-operation of the historian, the antiquary, and the philologist, was 303 found to be essential. Under the direction of Lieutenant (now Sir Thomas) Larcom, who conceived the idea of drawing together every species of local information relating to Ireland, and embodying it in a Memoir accompanying the Ordnance Survey Maps, Prrrir was employed to take charge of the topographical department, to collect all the mate- rials, and superintend the persons engaged in that part of the work. There, as the head of a literary staff, he had the assistance of several persons who possessed a good knowledge of the Irish language, and to whom he communicated his own methods of systematic inquiry, and _ the refinement of a more extended scholarship. It was from PETRIE that John O'Donovan and Eguene Curry received the training which enabled them afterwards to contribute in so many ways to that great development of ancient Irish literature which we have witnessed in the last quarter of a century. He became the informing spirit, the great instructor, of a school of Archzology. He not only laid down the prin- ciples, but exemplified upon a great scale the application to antiquarian science of the principles of a philosophic induction. Before his time, Trish antiquaries had brought discredit upon their pursuits by the va- riety of errors into which they fell. Some followed blindly in the wake of those who had gone before them, subjecting their conclusions to no examination, neglecting to gather and sift original documentary evi- dence, and hardly looking at the very objects of which they professed to give accounts. Others framed fanciful hypotheses, and then spent all their labour in casting about for arguments by which their theories might be supported. I need not go beyond the names of Vallancey and Beaufort for examples of the erroneous methods to which I have alluded ; and it is deeply to be lamented that the influence of their school is still felt amongst us; and that with avery large number of persons it seems to be a point of honour, or almost a matter of faith, to maintain the- ories in which the parts really played by our Celtic progenitors are assigned to Etruscans, Phcenicians, and races inhabiting regions still more remote. Against such misleading tendencies Prrris had to strug- gle, and he has combated them with a success which will be more fully recognised as the nature of his work comes to be better understood. He first showed how to make the contents of our ancient Irish MSS. avail- able for the purposes of antiquarian research. He had large collections made from them of passages bearing upon questions of topography, his- tory, architecture, and so forth. And he took pains to satisfy himself that the true meaning of these was furnished by scholars having a com- petent knowledge of the Irish language. He explored almost every part of Ireland himself, filling his sketch books with careful drawings of ancient remains; and it was by means of a comparison of these with one another, and with the notices of them contained in ancient docu- ments, that he established general and solid conclusions respecting their nature. The results of this process, especially those having a philolo- gical bearing, as exhibited in the ‘‘ Ordnance Survey Memoir,” called forth the expression of Pictet’s cordial recognition of the importance of his work, and of the merit of its execution. It is true thatthe literary and ec- R. I. A. PROC.—VOL. IX. 2¥ 334 clesiastical history of Ireland had received important elucidations from the labours of Archbishop Ussher, Sir James Ware, and Colgan; but before Perrie’s time little had been done to illustrate our topography, our pre- historic monuments, our military and ecclesiastical architecture. Sir James Ware had treated but superficially of these classes of antiquities. His assertion that the Irish had no knowledge of the art of building with stone and lime till the time of Henry IT. proves how limited was his know- ledge of this subject. He had hardly any acquaintance either with the actual remains, or with the Irish language, and was therefore unable to connect the antiquities with a history existing only in MSS. To- wards the close of his life he employed an Irish translator, but not till the greater part of his antiquarian collection had been completed. The contributions of Perris to antiquarian knowledge were not con- fined to the ‘‘ Transactions’ of this Academy and to the ‘‘ Memoir of the Ordnance Survey.” To touch more cursorily than they deserve on Guide Books, which in the earlier years of his life were indebted both to his pen and his pencil, the ‘‘ Dublin” and the ‘‘ Irish Penny Journal’ contain a large amount of matter of great interest illustrative of the pic- turesque ruins and the relics of art with which his rambles through Treland had made him acquainted. As the woodcuts of these cheap pub- lications show the true artist’s hand, so does the letterpress furnish numerous descriptions marked by all his characteristic accuracy and good taste. These volumes have thus acquired a permanent value. His rambles through all parts of Ireland called into exercise another of his natural gifts, which, like the rest, he made to contribute to the perpetuation of his country’s peculiar endowments. I refer to his mu- sical faculty. This, which was of a high order, enabled him to catch the native melodies which he heard from all manner of persons, and in as varying circumstances, and to commit them to his notebook. Part of the fruit of this loving care is to be seen in a volume published by the Irish-Music Society, in which about one hundred and fifty airs, thus rescued by him, are carefully arranged, and introduced by no- tices of their history, gracefully written, and full of interesting illus- tration of Irish character and social hfe. He had previously contributed many airs to the collections of Holden and Bunting ; and several hundred more, I am told, are still in his portfolios. Among his unpublished antiquarian works are the following :— ‘¢ An Essay on Military Architecture,” ‘‘ An Essay on Irish Bells,” 37. O-W4 100°00 Its specific gravity varied from 3-621 to 4-230.

Du Noyer, M.R.1.A., F.R.G.S.1., Senior Geologist, Geological Survey of Ireland, presented to the Library of the Royal Trish Academy 100 Drawings from Original Sketches of Architectural Antiquities, to form Vol. VII. of a series of similar donations. Mr. W. M. Hennessy read the following paper :— Toe CurracH oF KILDARE. It must be admitted that our most authentic and ancient extant records contain little or no reference to the original establishment of the Curragh of Kildare as a theatre, or common, for the cele- bration of national games, sports, and pastimes; and no allusion whatever to its having been allocated, at any period, to the per- formance of the mystic rites of the Druidical religion. The presump- tion that it was ever devoted, either in whole or in part, to the latter purpose, rests on very slight evidence, as we shall see; but that it was allocated to the former practice—nay, has continued to be so for the space of at least 2000 years—is very certain. The obscurity which surrounds the origin of all monuments belonging to the pre-historic period necessarily attaches to the ancient history of the Curragh. We know at least as much regarding it as the English know respecting the monuments of Stanton Drew and Stonehenge—the latter of which is asserted by some of the early English Chroniclers to have been trans- ferred thither from the ‘plains’ of Kildare. But of its use, the race 344 of men who erected it, or the date of its erection, notwithstanding the theory of its Saxon origin, which has lately occupied much attention, the people of Great Britain ‘‘ know as much,” remarks a recent writer, ‘as they do of the solid framework of the globe itself.” And yet English history has had the benefit of such elucidation as Caesar and Tacitus were able to afford. The works of their older historians— _ Gildas, Bede, and Nennius—also remain to the English, whilst many of our most ancient books of history are irretrievably lost. (See O’Curry’s ‘‘ Lectures,” p. 20, for a formidable list of the Irish MSS. which have disappeared. ) The oldest written reference to the Curragh of Kildare that I have been able to find is a very brief one, contained in an ancient MS. called the ‘‘ Liber Hymnorum,”’ preserved in the Library of Trinity Col- lege, Dublin, and which is believed to have been transcribed in the tenth century, from a much older volume. It occurs in the celebrated Hymn in praise of St. Brigid, which professes to have been composed by St. Brogan Claen, from a prose narrative given to him by his master, St. Ultan, of Ardbraccan,in Meath. The latter died in the year A. D. 656, at avery great age; and it may therefore be safely assumed that St. Brogan’s Hymn was composed not long after the year 600. It has been published by Colgan (‘‘ Trias Thaumaturga,’’) and contains internal evidence, if other testimony was wanting, of its antiquity. The ‘‘Mar- tyrology of Donegal,”’ in noticing the festival of St. Ultan, at September 4, states, ‘‘It was he that collected the miracles of St. Brigid into one book, and gave them to Brogan Claen, his disciple, and commanded him to turn them into verse; so that it was the latter that composed [ the hymn |, as it is found in the ‘ Book of Hymns.’”’ The reference to the Curragh is contained in the line ‘“‘ Zn Cazllech reidhed Currech,” 1. €., ‘the nun who races over the Currech (or Curragh).’’ The scholiast, in a contemporary gloss on the word “ Currech,’’ says, ‘‘ Currech, a cursu equorum dictus est.” Dr. Todd, who has quoted this gloss in his edi- tion of the ‘‘ Book of Hymns” (p. 67), remarks that this is ‘‘a curious proof of the antiquity of its use as a race-course ;” ‘to which,” he adds, ‘‘ perhaps some allusion may be intended in the description of St. Brigid as ‘the nun who drives over the Currech.’”’’ If the word reidhed had been translated ‘races,’’ instead of ‘‘ drives,” Dr. Todd’s suggestion would doubtless have been advanced with more confidence. The next reference to the Curragh, in the order of date, is contained in the ancient philological tract called ‘‘ Cormac’s Glossary ”’ (in Ivish, “ Sanasdn Ohormaic’), the authorship of which is ascribed to Cormac — | Mac Cuillenan, Bishop and King of Cashel, who was slain in the battle of Ballaghmoon, in the south of the county of Kildare, A. D. 908. This work, which is undoubtedly one of the most genuine fragments of ancient Irish literature that has descended to our times, has been edited by Mr. Whitley Stokes, from a MS. of the fourteenth century, in the collection of the Royal Irish Academy; but a fragment of it is preserved in the “‘ Book of Leinster,” a MS. in Trinity College, written about the year 1150. There is also a portion of this tract in a MS. in 345 the Bodleian Library, Oxford, transcribed in the year 1453, and a valuable copy in Trinity College of the early part of the fifteenth cen- tury. We cannot at present claim to possess Cormac’s autograph copy of the work; but Mr. Stokes, who has examined with critical exact- ness the historical arguments for and against Cormac’s authorship, admits that, if absolute authority is wanting to prove that the tract was composed by Cormac himself, the internal evidence is such as to con- vince competent judges that it must have been originally written, if not in Cormac’s time, within a century thereafter at most. In this glossary the word Currech, or Curragh, occurs twice, and is thus explained, viz.:— 1. “‘ Cwrrech, i.e. a cursu, 1.e. reidhe: Cuirrech, vero, do radh fro Sescend, 1.e. corra rechait and,’’ which, translated,~.reads “ Currech, i.e. @ cursu, i.e. running (or racing); Currech, indeed, is applied to a sheskin (morass), viz., cranes (corra) frequent it.’’ 2. Cormac again has “‘ Cwirrech, 1. e. a curribus, i.e. fich carpait,” which means ‘‘ Curragh, i.e. @ curribus, viz., contest of cha- riots.” The word ‘‘ fich’” is also glossed ‘‘ dewne,’’ ablative of ““ dian,’’—swift, vehement; and the explanation of Cormac, therefore, plainly points to chariot races. In O’Dayoran’s ‘‘Irish Glossary,’’ compiled in 1569, and also published by Mr. Stokes, ‘‘ Currach’”’ is explained ‘ Corr- dath, i.e. vathna corr” (corr-cath, i. e. the land of the herons). This explanation is, of course, entirely fanciful, and the glos- sarist has even committed a very great error, grammatically, in identifying Currech with Corr-cath. 'The anonymous author of a curious Latin poem, in the possession of Lord Talbot de Malahide, written in the seventeenth century, an extract from which may be seen in Mr. Gilbert’s ‘‘ History of Irish Viceroys”’ (p. 511), derives the name of the Curragh ‘a fessis equis,”’ ‘‘ from tired horses’’—as if the word were compounded of cortha (pron. corha) ‘‘ tired,” and ech, ‘‘ a horse.” Now, it cannot, I think, be doubted that, in furnishing an expla- nation of the word Curragh, and deriving it from ‘‘running”’ or “racing,” the compiler of this glossary, who was probably no other than Cormac Mac Cuillenan, had the Curragh of Kildare in view; for, although there are countless placesin Ireland bearing the name of Cur- ragh, singly or in compound, to which the description ‘crane land” | applies, or may have applied, I know of no other place so called to which _ the derivation a curribus can be held to be applicable. Cormac must | have known the Curragh of Kildare well. He lost his life almost | within sight of its green slopes; and the battle which proved fatal to _ him is asserted to have been caused by a dispute with the Monarch of | Ireland, Flann Sionna, regarding the right of presentation to the | neighbouring church of Monasterevan. Moreover, the Curragh of Kil- | dare never was a sheskin, or morass. Jt was not a sheskin in 484, 346 when St. Brigid founded her establishment on its borders, or for cen- turies anterior thereto. It was not a marsh in 705, when the Irish monarch Conghal, after devastating Leinster, apostrophized the Cur- ragh as the ‘‘ plain of the beautiful sward,”’ in stanzas preserved by the Four Masters; nor was it a marsh in the seventh century, when it was the scene ofa great battle; nor in the twelfth century, when Giraldus Cambrensis praised its fertility. In fact, the geological fea- tures of the surrounding country are opposed to the supposition that the Curragh was a marsh within the last 4000 years. Cormac’s second derivation of the name of Curragh, “a curribus,”’ which he explains by ‘“‘fich carpait,” or ‘chariot contests,” suggests the inference that chariot racing preceded simple horse racing in this country—an inference which is highly probable. The very ancient MS. known as Leabhar-na-h dre, now in the Academy’s collection, contains a remarkably valuable historical tale called ‘‘ Zoghail Bruidhne Da-Derga,” or the ‘‘ demolition of the mansion of Da-Derga,’”’ a Lein- ster chieftain who dwelt in the valley through which the River Dodder flows, about three miles above Tallaght. The late Professor O’Curry, in describing this tract, observes that ‘‘its composition must be referred to a period of very remote antiquity, the style of the construction and language being more ancient even than the Zain-bo-Cuatlgne (which is generally regarded as the oldest Irish tale); and of a character,’ he adds, ‘‘ totally beyond the power of ordinary Irish scholars to reduce to anything like a correct translation.”’ I venture to entertain the belief that the Bruidhen Da-Derga is, perhaps, the oldest Irish text now re- maining. The phraseology betrays no indication of the existence of Christianity in Ireland at the time of its composition. It professes to give an account of the destruction, by a band of pirates, of Da-Derga’s Bruidhen, or mansion (the name of which is supposed to be still pre- served in that of the village called ‘‘ Boher-na-breena,”’ or ‘“ the road of the mansion’’), and the murder of the Irish monarch, Conary Mor, whose death Roderick O’Flaherty refers to the year A. D. 60. I allude to this old tale, because it represents Conary as having on one occasion gone with four chariots to his ‘“‘clwche,” or games, to the Curragh, ‘7 Lifiu” (i.e. in the plain of Liffey), as the expression is.* The ‘‘ cluiche’”’ comprised all kinds of games, sports, and exercises, anciently performed at the Aenach, i.e. fair, or assembly—whether convened on the occasion of a national festival, the accession of a king, or for the purpose of holding the Aenach gubha, ‘‘ fair of sorrow,’’ or funeral rites, of some deceased chieftain; but in either case the imevitable ‘“‘ races,” or ‘‘ graifne,”’ formed a conspicuous element in the celebration. At the period to which I refer, namely, the middle of the first cen- tury, and during at least 200 years subsequently, chariot races would seem to have been the system of racing in vogue. Nay, from the exist- * Lifé was the old name of the plain of Kildare; and the river flowing through it, anciently called Ruirtech, thus obtained the name of “‘ Amhain Liffé,” or “‘ River of the Liffé.” 4 | 347 ing records, the chariot would appear to have then constituted the universal means of locomotion in this country. The explanation of this may be found in the fact, if such it is, stated in Leabhar-na-h Widhre (fol. 68, aa), that there was neither ditch, fence, nor stone wall erected in Ireland before the reign of the sons of Aedh Slaine (circa 660), but that the land was all in level tracts; and that fences then became ne- cessary as boundaries, owing to the multiplicity of houses. The erection of fences would of course tend to diminish the usefulness of the kind of chariots then in use, which we may well believe, notwithstanding the glowing description left to us of the chariot of Cuchullain, to have been little better than the heavy waggon of the Roman husbandman : — “'Tardaque Eleusinz matris volventia plaustra.” Be that as it may, when we come to the time of Cormac Mac Art, and the genuine Fenians, that is to say, about the year 260, we find the chariot races apparently superseded by horse racing ; for, whereas in our accounts of the true epic period of Irish history—termi- nated by the so-called Attacotic rebellion in A.D. 90—chariot races only are mentioned, the stories of the Fian, and pieces of more genuine history of the period, represent horse races as the delight of kings and chieftains; and whilst Conor Mac Nessa and the heroes of the Craebh Ruadh, or ‘‘ Red Branch,” are praised for the number and beauty of their chariots, Finn Mac Cumhail and his friends are complimented on the symmetry and fleetness of their steeds. The evidences on this point are numerous; but I shall only adduce one piece, and this simply as bearing on the subject more immediately under consideration. The oldest specimen of Ossianic poetry with which I am acquainted is a poem contained in the ‘‘ Book of Leinster’ — a twelfth-century MS. in Trinity College Library—in which Ossian laments his blindness, and expresses his regret that he cannot enjoy the Aenach, or Assembly of the Liffey, ¢.¢., of the Curragh, which he re- presents as having been inaugurated on the occasion by the King of Leinster. Then he narrates a visit which he paid in his younger days, with his father, Finn, to the assembly of Aenach-Clochmr, now Mon- aster-an-enagh, near Croom, in the county of Limerick, where horse races, or ‘‘ gratfne,”’ were got up in honour of Finn’svisit. Thence they pro- ceeded, adds the poem, to Tragh Beremhain, probably the ancient name of Ballyeigh strand, in Kerry, where another horse race took place, and where indeed the good old practice is still kept up. The copy of this poem which we now possess is of course not more than 700 years old; but who can fix the age of the original from which it was then transcribed into the ‘‘Book of Leinster?’ The statement that the public games celebrated on the Curragh were inaugurated by the king can be supported by many references of a similar kind. Indeed, the office of : presiding over such assemblies was part of the duty of a king, according to the Brehon Laws; and there are not a few entries in our annals | where a king is said to have been killed by a fall from his horse at an Aenach. This is also further confirmed by a clause in the well- 348 known testament called the ‘“‘ Will of Cathair-Mor, King of Leinster,” and subsequently Monarch of Ireland, who died about the year 174, who bequeaths to his son Crimthann, amongst other bequests, ‘the leadership of the games of the Province of Leinster,” which I take to include the games of the Curragh. This remarkable document has been published in the ‘“‘ Book of Rights,’”’ by Dr. O’ Donovan, who observes, in the preface, that it must have been written some centuries after Ca- thair’s time; but O’Flaherty treats it as a document contemporaneous with the testator; and it is evident that the copy which the learned author of ‘“‘Ogygia’’ possessed was more ancient than O’ Donovan’s texts, as the clause in which Cathair bequeaths to his son Crimthann, ‘‘ Po- testas, qua ludorum prefectus per Lageniam erat constitutus,’’ is not found in the later copies. There is another very ancient poem contained in the ‘‘ Book of Lein- ster,’ in praise of St. Brigid, the various Kings of Leinster, and the more important places in it, including the Curragh. The author’s name is unfortunately not given; but I have little doubt that it is the com- position of one Orthanach, another of whose productions is also pre- served in the same MS., although in vol. v. of the Academy’s ‘‘ Proceed- ings,’ page 171, it is stated that no mention of this writer occurs in any known document except in an Irish MS. in the Bodleian Library. There are two persons of the name mentioned in the ‘‘ Annals of the Four Masters’’—Orthanach of Cill-Foibrich, or Kilbrew, in Meath, whose obit is given at the year 809; and Orthanach, Bishop of Kildare, who died in 839. I think the latter, who in the Bodleian MS., is called *‘Orthanach of the Curragh of Kildare,” was certainly the author of of this poem, as it manifestly appears to be the production of an eccle- siastic, and to have been written before the year 835, when St. Brigid’s remains were transferred for safety to Downpatrick, as the writer ex- pressly refers to Kildare as her ruaim, or place of sepulture. The author apostrophizes St. Brigid, salutes her as the princess of the men of Leinster, and states that, although to her then belonged the plain of the Liffey, which he afterwards refers to as the Curragh, yet before her time it belonged to all in succession— ““ Indiu cid latt Liphe Lir, Ro bo thir caich ar nuair.” which I understand as signifying that it was a common before the time that the people of Kildare came to regard it as the appanage of their patroness, from which period it has undoubtedly continued to be sO. : After enumerating some of the kings who reigned over the Curragh, t.e., over Leinster, the poet adds— ‘“* Marid Cuirrech cona li, Ni mair nach Ri ro boi foir.” ‘The Curragh, with its beauty, remains ; But there lives no king who was over it.” 349 The verdure of its sward, and the shouts of its assemblies, are also men- tioned, as well-as the curious condition which seems to have been im- posed by custom on any celebrated stranger visiting the Curragh, which consisted in his having to perform a ‘‘cor,’’ turn, or circuit round it. From this word “cor,”’ or circuit, some persons might be inclined to de- rive the name of ‘‘ Curragh;’’ and it is true that the old road leading from the Priory, or graveyard, of Kildare, towards the Curragh, is still called Bohereen-na-geor,”’ or ‘‘ the little road of the turns (or circuits) ;” but the very ancient authorities of Brogan Claen and Cormac forbid our setting aside their explanation of the word Curragh. Local tradition assigns the honour of making the Curragh a common to St. Brigid, who is represented as having received from the King of Lein- ster, for removing a deformity under which he laboured, as much land as her mantle would cover; and itis added that but for a rent made in the garment, through the avarice of one of her female companions, the entire surface of Ireland would have been embraced in its folds. There is no reference to this alleged grant in any of her lives. In most of them, how- ever, she is stated to have had pastures on the Curragh, to which she never prevented the neighbouring people sending their cattle. Both history and tradition here plainly point to the fact of the Curragh hav- ing been a common from the year 484, when Brigid founded her little church of wattles beside the old oak of Druim Criadh (‘ Ridge of Clay’), as Kildare was anciently called. It is probable, also, that St. Brigid did not interfere with the races, whatever may have been the case as regards the other Pagan celebrations; for, although she is represented by her biographers as ‘‘ never for one moment diverting her attention from holy contemplation, but in constant converse with God by meditation in heart and mind,” her ancient lives prove that she was not averse from riding in her chariot over the Curragh, or opposed to the exercise of legitimate amusement being practised there; and indeed the “‘ fatche,”’ or “ green,’’ formed an adjunct to the old church or monastery, as well as to the Dun, or residence of the chieftain. Nor were the races dis- countenanced, apparently, by her successors, some of whom are occa- sionally dignified by their biographers with the agnomen “ Cuirre- thach,” or “‘ the racing,” as the Abbot Cobhthach, who died in the year 868, and a fragment of-whose elegy is preserved by the Four Masters, in which he is called ‘‘ Cobhthach Currigh Cwirrethach’’—1. e., ‘‘ the racing Cobhthach (or Coffey) of the Curragh.”’ Besides, we have it on record that kings were sometimes accompanied by the ‘‘ chiefs of the . clergy and laity,’’ when celebrating the Aenach, or games. It appears from the most ancient Irish MSS., that from a very re- mote period every province in Ireland possessed an Aenach, ‘‘fair green,” or arena, where the men of the province, old and young, assembled at stated times, under the leadership of the king, to celebrate their festival games. And such was the regularity with which these celebrations _ were held, that whenever intermitted on account of wars or other inevi- | | _ able causes, the Annalists deplore the circumstance in feeling terms. Inthe old list of Irish Triads, contained in a stave of the ‘* Book of Lecan’’ R. I. A. PROC.—VOL. IX. oA 300 (which by some chance has got inserted into the vellum MS. classed H. 2, 17, in Trinity College Library), the three great Aenachs of Ire- land are stated to have been Aenach Croghan, in Connaught; Aenach Taillten, in Meath; and Aenach Colmain, or the fair of the Curragh. The green of Croghan, in Roscommon, was frequented by the people of the trans-Shannon district; that of Taillten, or Teltown, in Meath, in which Tara, the ancient seat of the Irish monarchy, 1s situated, was the ~ principal place of assembly for Leath Chuinn, Conn’s half, or the north- ern part of Ireland; and the Curragh served for the southern half, called Leath Mogha, and probably for the whole country. I may ob- serve that the games of Taillten, or Teltown, continued to be celebrated every first of August, down to the end of the twelfth century. Even from that period hurling, wrestling, and other manly sports were an- nually carried on there up to a recent date; and the Hill of Lloyd races may possibly be arelic ofthe ancient practice. In addition to these prin- cipal places, each sub-territory had also its special arena. The men of Northern Ulster assembled at Emania, now the Navan Fort, near Ar- magh. The tribes about the now county of Limerick congregated to Aenach Clochair, now Monaster-an-enaigh, near Croom. ‘The inhabi- tants of Hy-Kinsellagh, or Southern Leinster, met at Loch Garman, or Wexford; and the place where they enjoyed their games is still called the Fathy, or Paitche, t.e. ‘‘fair green’? of Wexford. The green of Cashel is also celebrated in history, as well as that of Aenach Urmumhan, or the Aenach of Ormond ; from which word Aenach, or An-Aeanach, the name of Nenagh is derived. The dates at which all these places were founded—except the Cur- ragh—are given, and range from some centuries before the Christian era to A. D. 400; but no reference to the exact period when the Curragh was established as the Olympian theatre of the Irish is to be found in our MS. remains. Dr. O’Donovan, who devoted much attention to the elucidation of its history,- was only enabled to conclude that it was a plain from the most remote age. However, it seems to have been used as a national arena in the century before Christ, when Art, son of Mesdelmond, fixed his residence on Dun Ailind, or Knock Allen, on its eastern border, to which an old road, still traceable, led through the Curragh. The ancient tract, called the ‘‘ Dinnsenchus,” originally compiled in the sixth century, of which we have a copy in the ‘‘ Book of Leinster,’’ contains a poem on the erection of Dun Azlind, or Knock Allen, in which occur the lines, ‘“* Aillend uenach diar nogaib Raith Airt cona Righ rodaibh.” “« Ailind, place of assembly for our youths— Rath of Art, with its royal roads.” There ig no doubt, I think, that the celebrity here claimed for Aclind, as a place of assembly, or Wundine, is borrowed from the character of the Curragh which stretched before it, as Knock Allen is too steep to have ever served as a place for the celebration of the games appropriate to an Aenach. 301 The places of public assembly, as I have remarked, were generally confined to the inhabitants of the respective districts; but it would seem that the Curragh was frequented by people from all parts of Ire- land. Thus Conary Mor and his companions who belonged to the northern division, are represented as having attended its games. We have it on very ancient authority that two centuries later the promis- cuous band of Finn was in the habit of participating in the sports. _ The ‘‘ Book of Munster,”’ as preserved in the ‘‘ Book of Lecan,”’ states . that Fiacha Fidh-gheinte, ancestor of the O’ Donovans, and other chief families of Munster, and who lived in the fourth century, obtained the surname ‘‘ fdh-gheinte,” which is supposed to mean ‘‘ wood maker,” “quia fecit equum ligneum in Crrcino Colmain, in Campo Liphi.”” The explanation may appear fanciful, and suspiciously suggestive of Epeus and the Trojan horse; but it nevertheless implies that the writer knew the men of Munster were admissible to the sports of the Curragh. Again, at the year 825, the Annals record the destruction of Aenach Colmaim, i.e. the Assembly of the Curragh, by Muiredhach, King of Leinster, against the South Leinstermen, on which occasion many were slain. South Leinster was at that time, and had been for 600 years previously, a distinct kingdom, and had its own place of assembly at Loch Garman, or Wexford. Its people are stated to have celebrated the Curragh games also on other occasions without interruption; and the contention in 825 may have been owing to their having dispensed with the usual inauguration by the local sovereign, as the disturbance of a fair, without weighty reasons, was severely punished under the Brehon Laws. In the year 954, also, Congalach, Monarch of Ireland, is recorded to have proceeded into Leinster, and held the “ fair of the Liffey,”” or Curragh, for three days; and, although the Leinstermen did not interfere with the celebration, Congalach, at their instigation, was intercepted by the Danes of Dublin, on his return home, and slain at Adlen-tighe-Giughrain, which was very likely the ancient name of Inchicore, near Dublin. Hence it would appear that all comers were free to make use of the Curragh for the purposes to which it was adapted. Tt is not necessary to the object of this paper to refer to the many occasions on which the Curragh of Kildare was the theatre of more hostile assemblies. Situated almost on the boundary of the warlike kingdoms of Meath, Leinster, and Offaly, it formed a convenient battle ground for rival armies. Neither shall I detain the Academy in attempting to define the character or origin of the tumuli with which its long ridge is dotted, and which, not being ramparted, are supposed to have been used, not for purposes of residence, but as places of inter- ment. : The fame of the Curragh as a Druidic establishment does not rest | on avery strong foundation. Moore, in his ‘‘ History of Ireland,” vol. 1., |p. 28, has given currency to the notion. ‘‘One of the old English | traditions respecting Stonehenge,’ he says, ‘‘is, that the stones were | transported thither from Ireland, having been brought to the latter 352 country by giants from the extremity of Africa; and in the time of Giraldus Cambrensis there was still to be seen, as he tells, on the plain of Kildare, an immense monument of stones, corresponding exactly in appearance and construction with that of Stonehenge.’ Giraldus, however, does not say that the monument was there in his time, but that there was in ancient times a stupendous pile on the plains of Kil- dare, near Naas, and that ‘‘ certain stones,’’ ‘‘ guidam lapides,’’ exactly resembling the rest, were there in his time; and although it has been supposed that the ‘‘Nasensi’’ of Giraldus was a misreading of *¢ Darensi”’ or ‘‘ Darensis,” as Kildare is usually Latinized, it is likely that ‘‘ Nasensi”’ is right; and that, by placing the locality close to Naas, Giraldus meant either the enormous pillars still remaining at Fornaught, or perhaps those at Punchestown. But the account which Giraldus gives of the removal of the Stone- henge monument from Ireland is copied from the ‘‘ Historia Britonum”’ of Geoffrey of Monmouth, who represents Uther Pendragon as having come over here, by the advice of Merlin, and transported the monu- ment from the mountain of Killarus (probably the Hill of Fornaught), after having defeated Gillomanius, who then reigned in Ireland. As an instance of the untruthfulness of Geoffrey’s statement, I may ob- serve, what Mr. Charles Haliday was the first to notice, that the word Gilla, ‘‘servus,” or “‘puer,” is not found in the composition of any Trish proper name prior to the advent of the Danes, from whom it was probably borrowed; and no name beginning with ‘‘ Gilla” appears in the Irish Annals before the end of the ninth century. Writing of Kildare, Giraldus observes, ‘‘In this neighbourhood there are some very beautiful meadows, called ‘ Brigid’s pastures,’ in which no plough is ever suffered to turn a furrow. Respecting these meadows, it is held as a miracle that, although all the cattle in the province should graze the herbage from morning till night, the next day the grass would be as luxuriant as ever. ‘*Cropt in a summer’s day by herds, the dew’s Refreshing moisture verdure still renews.” It is to be regretted that this excessive fertility does not still characterize the Curragh, which is locally called ‘‘the short grass;’’ and the young men of Kildare are known as ‘‘the boys of the short Tass.” : The Curragh seems also to have been regarded by the Anglo- Nor- mans as a common pasture; and Mr. Gilbert, in his valuable ‘‘ History of the Irish Viceroys”’ (p. 510), has published a curious Parliamentary de- cree of the year 1299, in which it is expressly so called :—‘ Inhibi- tum est, sicut antiquitas fierl consuevit, quod porci de cetero non pascant in Coraghto de Kildare, quod est communis pastura, et in solio Domini Regis. Et vicecomes puniat illos qui porcos suos fugent vel habeant ibi fodientes vel pascentes, prius per finem, et postea per amissionem porcorum illorum, et gravius si sepius sic delinquant.” Among the Ordnance Survey papers in the collection of the Academy is preserved a curious tract called a “‘ Descriptive Account of the County 3038 of Kildare,” drawn up for Sir William Petty, by a Mr. Thomas Monk, in the time of the seventeenth Earl of Kildare, and therefore between the years 1660 and 1664, in which the Curragh is thus referred to: ‘* Near the centre of this county is the Curragh of Kildare, a large spatious plaine, and common to all the adjacent neighbourhood, who find it a rich and commodious, as well as healthful pasturage, especially for sheep, that bear a fine staple, and the finest flesh of any in the king- dom—it being thronged with flocks all the year round. It is about nine miles in compasse, and togeather with the adjoyneing grounds, is reckoned one of the most pleasant sytes these kingdoms anywhere can shew: the easie assents yeildinge noble and various prospects, and the gentle declineings give content to the wearied traveller, as well as re- create and please the gentiele horsman and keeper; it being a place naturally addapted to pleasure; and its vicinity to Dublin—being but seventeen miles distant—occasions that hither repaires the Lord Lieu- tenant, or Chiefe Governor, when his Majestie’s important affaires will admit leisure to unbend, and slacken from trying cares. Hither are also seen to come all the nobility and gentry of the kingdome, that either pretende to love, or delight in hawking and hunting, or raceing; for in this clearer and finer aire, the falcon goes to a higher pitch, or mount, soe as often to be scarce visible; the hounds enjoy the scent more freely, and the courser, in his swift carreare, is lesse sensible of pressiure or opposition then other where.”’ A few years previously also, z.¢. in 1657, the Commissioners ap- pointed to carry out the Act of Settlement returned the Curragh as a pasturage common to various towns, although in the reigns of James I. and Charles I. the right of pasturage thereon was granted to certain patentees; but it would seem that these grants were re-grants of rights previously forfeited. it remains to say a word as to the extent of the Curragh. It com- prises at present 4885 acres; but it seems likely that it was anciently much more extensive. Dr. O’ Donovan and others have been of opinion that the Curragh extended to the River Liffey on the eastern side, as it is referred to in the ancient records as being ar bru Life, 2.e. ‘‘ on the brink of the Liffey.” But the expression ar bru Liféis only relatively used, in the same way as Glasnevin is described in the ‘‘ Martyrology of Donegal” (p. 272), as “‘for bru abhainn Lifé,’”’ ‘on the brink of the River Liffey,” although it is much farther from the river than the pre- sent eastern limits of the Curragh. It is very probable, however, that the Curragh extended in another direction as far as the town of Kildare. St. Brogan asserts in his hymn that St. Brigid built her establishment in a plain, ‘in campo extruxit suam civitatem.” There are many no- tices in her lives, implying that the land in immediate contiguity to her church was a plain. This is also supported by a scholium at the ist of February, in the Festology of Aengus Céle Dé, a copy of which is preserved in a twelfth-century MS. in the Bodleian Library, which represents the saint’s cows as having on one occasion given so much milk, that the surplus, after filling all the pails, formed the lake called 354 Loch Lemnachta, or ‘‘ New-milk Lake,” to the north of the place. The lake in question is probably the small sheet of water now called Loch Minnaun, or the Lake of the Kids, lying a few perches to the north- west of Kildare; and as it is represented as having been in or near ‘‘ Brigid’s pastures,” it may have probably been within the ancient limits of the Curragh. I may close the present paper with the following extract, already published in Mr. Gilbert’s ‘“‘ Viceroys,” from the Latin poem in the possession of Lord Talbot de Malahide, to which I have already re- ferred :— ee ‘“‘ Est locus almus apex ubi se Kildarius astris Inserit et socium lambunt fastigia coelum, Quem prope campus adest, immensi jugeris zequor, , Vomere quem nulli, vel adunci vulnere aratri, Sulecavere boves; nulle secuere lacunz. Non illic surgunt virgulta, lapisve superstes Limes, agro positus ; nullis hic terminus arvis ; Terra patens, preebens promiscua pascua, nullo Limine septa scrobis, sed toti libera regno. Si foret hic lapidum jactu reparanda virum stirps Perdita diluviis, hic frustraretur inanis Deucaliona labor; silices nec Pyrrha morandis Hoc reperire queat, mulieribus irrita, Campo.

Scilicet hee toties prata ungula trivit equorum Lassa Geraldiadum, cum se Mavortia pubes Exerceret ovans; et equis, quee maxima virtus, Expertura suis varium certamen iniret.” Thus translated by Denis Henry Kelly, Esq. :— ‘* Where soars the ancient Tower of Kildare, Amidst the stars, and leaves in ’ts kindred Heaven Its trace, a place there is most passing fair ; And near ’t, a level plain of many an acre, Which coulter ne’er, nor oxen with curved share Have into furrows riven; there no dykes Have e’er been cut; no brushwood rises there; No. stone stands, planted as an ancient landmark ; No bound’ries here to point out sep’rate fields. In common past’rage open lies the land, Nor hedge, nor ditch is there—all, all is free! If here Deucalion, to renew man’s race, Sought stones to cast behind him, vain his task ! Nor in this plain could Pyrrha flints have found, To supersede, how vain! the female sex. So far around this plain, on every side, No eye of human being can descry Its limit—the great stones upon its confines 309 So far asunder stand! One likeness has it, And only one, which in the least comes near it— The calm blue sea, O AXolus, which stands By any breeze or breath of thine unrufiled. Its name, from wearied steeds, the Curragh takes— A name of yore in tongue vernac’lar given, But which in Greek is called an Hippodrome— Because this plain on ev’ry side’s cut up By the tired hoofs 0’ th’ Geraldines, when there That martial race, exulting, exercise Their steeds, and try their mettle —thus to test Which fleetest is, ere ent’ring for the Stakes.” In conclusion, I have to regret that the references to the Curragh are so few and fragmentary, that the most diligent search has not enabled me to present to the Academy a more specific account of its his- tory and antiquities than the present imperfect sketch. _ Mr. Evernr Atrrep Conwett read a paper, entitled EXAMINATION oF THE ANCIENT SEPULCHRAL Carrns on THE LoucHcREW Hitts, County oF Mzaru. Parr I. SUBJOINED are extracts from this paper, and an abstract of other details: — Tn the extreme north-west angle of the county of Meath, commenc- ing about two miles south-east of the neat and flourishing little town of Oldcastle, and directly overlooking the beautiful demesne of Loughcrew, there runs from west to east a range of hills, about two miles in extent. The highest peak, known as Shabh-na-Caillighe, attains the height of 904 feet, and, being the only eminence in the county assuming the name or character of a mountain, forms a prominent feature in the land- scape. The whole range consists of Lower Silurian rocks, which occupy a large extent of country inthe neighbourhood. On the north the slate rocks form the low grounds round Lough Ramor, while to the south and west lie the comparatively low, undulating, limestone plains of Meath and Westmeath. The prospect from the summit of any of the peaks is not to be sur- passed in. any other locality in the country. or pastoral beauty it is unrivalled: while, for comprehensive extent of view, perhaps, no other point in the kingdom could have been so well selected for the necropo- lis of the chiefs who inhabited the central prairies of Ireland. The mountains overhanging the bays of Carlingford and Sligo are visible, eivying a telescopic view of Ireland from sea to sea, about its narrowest part. Persons knowing the country well are accustomed, with the aid of a clear horizon, to point out from these hills elevations in eighteen out of the thirty-two counties in Ireland. This is not surprising, as it can be easily shown by trigonometry that the square root of once and a half the height in feet of any elevation on the globe’s surface is equal to the eee of the offing, or sensible horizon, in miles; and thus Sliabh-na- Caillighe, haying an altitude of 904 feet, commands a view of at least 306 thirty-seven miles all round, in a perfectly clear atmosphere, not taking into account that atmospheric refraction would increase this distance by about three miles. Now, a circle of thirty-seven miles in radius, swept round Sliabh-na-Caillighe on the map, will include within its range, or nearly touch, the counties of Fermanagh, Tyrone, Monaghan, Armagh, Down, Louth, Meath, Dublin, Wicklow, Kildare, King’s County, Queen’s County, Westmeath, Roscommon, Sligo, Longford, Leitrim, and Cavan. Following up this line of calculation, any mountain at- taining the height of 2000 feet, under favourable circumstances, might be visible, if not more than ninety-two miles distant; which would include every mountain of 2000 feet in height and upwards in every county in Ireland, except in Cork and Kerry. Such a site, however, was no doubt selected in order that these great tombs might form conspicuous objects in the horizon from the greatest possible number of places. My first visit to these remarkable hills was on a pic-nic excursion, accompanied by my wife, and was made on Tuesday the 9th of June, 1868; when, to my great astonishment, I found this commanding site studded with the remains of a necropolis of pre-historic age, greater in extent than anything of the kind yet thoroughly examined in Europe. Although at a distance of about twenty miles from my home, I soon afterwards paid as many visits to the place as my limited time and the inconvenient distance permitted me to do—some of the results of which I have already had the honour of laying before this Academy on two former occasions. When I first stated that I had discovered a series of hitherto un- — noticed and undescribed cairns, extending for two miles along a range ~ of hills, within forty miles of the city of Dublin, I was laughed at, — naturally enough. I can only attribute their being left for me to in- vestigate to the fact that, up to the time the omission was drawn at- — tention to by me, the only indication of their existence on the Ordnance ~ Survey Maps was a mere dot or two, with the word ‘‘ Stones” appended: — and the local knowledge of their origin and use went no further than ~ what the late eminent Dr. O’ Donovan so humorously describes in one of ~ his ‘‘ Letters containing information relative to the antiquities of the County of Meath, collected during the progress of the Ordnance Sur- — vey,’ of which I submit a copy—writing of the parish of Loughcrew. — “Kells, 30th July, 1836. me hovel are Te hills he a =) minds in this sane having three heaps [carns] of stones on their summits, with which the follow- ; ing wild legend is connected. A famous old hag of antiquity, called ; Cailleach Bhéartha (Calliagh Vera), came one time from the North to — perform a magical feat in this neighbourhood, by which she was to ob- — tain great power, if she succeeded. She took an apron full of stones, _ and dropped a carn on Carnbane; from this she jumped to the summit of Sleve Na Cally, a mile distant, and dropped a second carn there: from this hill she made a second jump, and dropped a carn on another hill, _ about a mile distant. Ifshe could make another leap, and drop the — 357 fourth carn, it appears that the magical feat would be accomplished; but, in giving the jump, she slipped and fell in the townland of Patricks- town, in the parish of Diamor, where she broke her neck. Here she was buried; and her grave was to be seen not many years ago in the field ealled Cul a’ mh6ca (7. e. back of the moat), about two hundred perches to the east of the moat in that townland ; but it is now destroyed. “This is the very old lady whose shade still haunts the Jake and earn of Slieve Guillion in the county of Armagh. Hername was Avlin, and it would appear from some legends about her that she was of De Danannite origin. ‘She is now a Banshee in some parts of Ireland, and is represented in some elegies as appearing before the deaths ofsome persons. I know nothing more about her, but that on one occasion she turned the cele- brated Fin Mac Cooil into a grey old man; but his soldiers dug through the mountain of Slieve Guillion injArmagh until they drove her out of her cave, and forced her to restore Fin to his former beauty and symmetry. “Does her name, Giblin bheupta ng SHhuilinn, appear in the genealogies of the Tuatha De Dananns? ‘ diameter of circle ; AD:'BD=y: diameter of circle. Hence equation (8) becomes sin A sin .B gin C eR i a (9) This is the equation of the circumscribed circle. 5. The equation of the inscribed circle ofa plane triangle has been derived in Art. 3 from the equation (2) of a pair of circles touching three circles. Conversely, the equation of a pair of circles touching three others may be derived from the equation of the inscribed circle of a plane triangle. For let = (fig. 3) be the circle inscribed in the triangle ABC, the equations of whose sides are a=0; B=0; y=0; and let the circles S, S’, S”, touch = at its points of contact with the sides of the triangle ABC; then denoting the radius of = by #, and the radii of S, 8’, 8”, by 7, 7’, v’, respectively ; if any point Q be taken in &, the result of substituting the co-ordinates of Qin S=2(#-v7) multiplied by the re- sult of substituting the co-ordinates Q in a.

The equations of the other pairs of circles may be similarly derived i from the equations of the exscribed circles.—e. E. D. 6. The equation JIS +f m8! + /n8" = 9, when cleared of radicals, becomes & PS? 4 mS? + 0S — 2lmSS! — 2mn8'S" — 2nl8"S= 0 (10) ; Now, since this may be written in either of the equivalent forms (IS — mS’) + n&" (nS" — 218 — 2m8’) (11) am (m' — nS")? + 1S (1S — 2m’ ~ 2n8") (12) (n 8" —18)2 + mS! (mS'-InS"- 218) (18) - it follows that the pairs of circles 7 J WS +f m8! + / nS! =0 touch § at the points S= 0, mS' ~ nS” =0; Pauley a istic (0), nS’ —IS=0; OUT as iS = 0, LS - mS’ = 0. Hence, we have the following method of constructing the points of contact on the circles S, S', 8", with a pair of their tangential circles:— 401 Describe the circle 7S —mS’=0; this circle, coaxal with S, S’, will intersect S” in two points, which will be points of contact. Again, describe the circle mS’—mS"; it will intersect Sin the points of con- tact. Lastly, describe the circle nS” -7S=0, and it will intersect S’ in the points of contact. 7. Since the circle JS — mS'=0 intersects S’’=0 in the points of contact of S” with the pair of circles 1S + / msS' +\/ nS" = 0, 1S — mS’ —-(l-m) 8" =0 passes through the points of contact. Now, S — 8” =0 is the radical axis of the circles S, 8”, and S’- S”=0 is the radical axis of the circles S’, S”. Hence, denoting the radical axis of Siena Ane i ganemer ia i Be 8 5) uae, this equation becomes | mA —-1lA’=0; | hence, A_A’_ l mM In like manner, the points of contact on S are constructed by drawing | the line : | and the points on S’ by drawing the line WI A ey eh eS), n 1 | The chords of contact of the three circles S, S’, 8”, with their four ) pairs of tangential circles, are given by the four systems of equations— Ai Ale Ar Vim Se ey a Nae A’ On et Ae: Al AP ie was ce) AeA!

Since the discriminant of the equation (10) does not vanish, it ] follows that it is not the product of two simple factors of the form AS + pS! + vS” = 0 MS + pS! + v/S!’ = 0 Hence the equation of a circle (=) touching He circles, S, 8’, 8”, cannot be expressed in the form \S + pS’ + v8" = 9. The result of Art. 8 may be proved independently, as follows, — and we can thence infer, conversely, that the discriminant of equation (10) ought not to vanish :— For, if possible, let the equation of a circle A touching three J circles S, S’, S’”’, be of the form XS + pS’ + vS”= Hence, AS + pSl= SZ — v8”, Now, since = touches 9”, the circle AS +8’ =0, which is coaxal with § and S’, also touches S” at its point of contact with =; but we © have seen (Art. 6) that the circle coaxal with S and S’, which passes through the point of contact of = with S”, cuts S”, instead of touching it. Hence the equation of a circle touching S, S’, 8”, cannot be of they . form VS + pS’ + v8" = 0.—a. B.D. This conclusion accords with the fact that three circles, S, S', 8", being given, the form AS + pS’ +vS"=0 is not sufficiently general to 3 express the equation of any fourth circle. For the equation of any — circle contains three independent constants, while \S+pS'’+vS"=0 | contains but two, viz., the ratios X: v and p: v. 10. The equations (11), (12), (18), of Art. 6, being all of the z , form R?= LM, hence the pair of circles / IS aS ms! + J nS mu”! also «| touches the circles LS — 2mS' — 2n8"” = mS! — 2nS''- 218 = . n§" — 218 - 2mf! = 4 Again, the circle 1S + mS! + nS" evidently passes through the inter sections of the pairs of circles S and 1S - 2mS! - 2nS"; S’ and mS’ — 2nS" - 218; S’ and nS" - 218 - 2mS; 403 and is therefore coaxal with each pair. Hence the three lines joining the centres of these pairs of circles are concurrent. Hence we have the following theorem:— ~— The pair of circles »/ 7S + / mS! +./nS” = 0 touching three circles, S, 8’, 8”, also touches the three other circles LS — 2mS! - 2nS"=0; mS’ — 2nS"” — 21S = 0; nS" — 218 —- 2mS8'=0; and the lines joining the centres of these circles to the centres of S, S’, S”, respectively, concur to the centre of 1S + mS’ + nS”. | 11.

(28) 12. We shall conclude this part of the subject of this Paper by applying our principles to prove Dr. Hart’s celebrated extension of _ Feuerbach’s theorem :— : ‘Taking any three of the eight circles which touch three others, a - eircle can be described to touch these three, and to touch a fourth circle _ of the eight touching circles.” Now, since the combinations in threes of eight things is : : - = 56, _ this theorem makes it necessary that we should have fourteen circles, | which we divide into two systems of circles—one system containing ) eight circles, and the other containing six. Since the eight circles which touch three given circles are, four of them, the inverse of the other four, with respect to the circle which euts the three given circles orthogonally, they may be denoted in pairs as -— Gat Bp sa yy) eoe.; 404 then it is evident that VIS + / mS! +/ nS" = aa AIS + / mS! + 6/018" = BB!

(a) Similarly, the equation of any circle touching the pair of circles Bf’ will be of the form (w? = pl) LS = (p! - 1) mS’ + wn'S” = 0. (5) Tn order that equations (a) and (6) may represent the same circle, we must have for the system of six circles. Hence » and pw’ are determined, which proves the proposition ; and we have the following system of six circles :— aa' Bp’ are all touched by a fourth circle.

E. D. 13. A very simple geometrical demonstration can be given of this part of Dr. Hart’s theorem;—in fact, it is inferred at once from the following principle, which occurred to me some time since :— If two circles, P’, Q’, be the inverse of two other circles, P, Q, with respect to the same circle, X, the four circles, P, Q, P’, Q’, have four common tangential circles. This is evident. 14. Proof for the system of eight circles :—Let S, S’, S” (fig. 4), be the three given circles, any or all of which may be right lines, and a, B, y, ©’, four circles described touching them similar to the exscribed and inscribed circles of a plane triangle, I say, a, B, y, ’, are all touched by a fourth circle, besides the three circles S, S,’ S”. Demonstration.—Let the direct common tangent toa pair of circles, a and f, for instance, be denoted by the notation af, and the trans- verse commmon tangent by «$ with an understroke; then we have, attending only to the magnitudes of the rectangles, by Art. 1, since S is touched by f, y, 6’, on one side, and by a on the other, aB > yo + a0 * By — ay: BO = 0; » (a) in like manner, ay’ BS + 46 aB- By‘ ad =0; (d) and aB + y6'+ BO ay - By * ad = 0.

E. D. II. EQUATIONS OF THE SIXTEEN SPHERES IN PAIRS WHICH TOUCH FOUR OTHERS. 15. If A, B, C, D, be four points in a plane, then denoting their three pairs of connectors by the following notation, BC, AD, by i, p : CA, BD; 5; 78, es AB, CD, 99 ne, yt 5 we have (Salmon’s ‘‘ Geometry of Three Dimensions,” Art. 50,) i p-g)(p-r)+m(q-r)q-D+n(r—p) (r-9) +lp(l—-m—n)+mg(m-n-1)-—ur(n-l-m)+lmn=0.

The equation (26) between the connectors of five points on the stirface of a sphere is the analogue of Ptolemy’s theorem for four points on a circle, and can be enunciated in a very concise manner by the help of the following considerations :— 1°. The entire number of lines of connexion of five points tee 10 a 2°. The entire number of triangles which can be formed by combin- 5x4xs3 ing the five points, three by three, is — 0; 1:2°3 3°, The entire number of pentagons which can be formed having : aS 4x3x2xl the five points for vertices = Sa = 1. 408 Then, the sum of the ten products formed by multiplying the fourth power of the line joining any two points by the continued product of the squares of the sides of the triangle of which the three remaining points are vertices is equal to the sum of the twelve products formed, each, by multiplying together the squares of the sides of each of the twelve pentagons of which the five points are the vertices. 17. Supposing the points A, B, C, D, £, of Art. 14 to be on a plane, and that spheres whose diameters are 6, 6’, 6”, 6”, 6”, touch the plane in those points; then inverting the whole from any arbitrary point in space, and denoting the common tangents to the inverse spheres by the same notation as that of Art. 14, viz., the common to the inverse of the spheres at B, C, by 73; 7> 33 val D, 7) Pp ; and so on; then we have from equation (21) the following theorem :— If five spheres, A, B, C, D, #, touch a sixth sphere, =, the relation | 0), mt, B, mn, 0, 1, @,_P; mi 0, te O (27) DB) = o> se 053, 0, a, B, Y> 6, 0, holds between the common tangents of the five spheres, the common tangent to any pair of spheres being the direct or transverse, according as the pair of spheres to which it is drawn have contacts of the same or of opposite kinds with the sixth sphere, =. 18. The theorem of Art. 17 is an extension of the theorem of Art: 15, analogous to the extension which the theorem in Art. 1 is of Ptolemy’s theorem, and an analogous use can be made of it. For, supposing the sphere at the point # to reduce to a point, and denoting the other four spheres by S, S', 8”, S”, then we get the equa- tion of the pair of spheres touching S, S,' 8,” S’”, OF, MP. 8) N, 0, 9 q S’ m, 4, 5 Te lO (28) ; 0, sv Pea 3 A HSae ome arey 130) precisely in the same way as the equation of the pair of circles touching three circles was derived in Art. 2.—@.

Denoting the equation (28), for shortness, by the notation Pl, m, n, p, 7, 7,)=0, and the transverse common tangents by the same notation as the direct common tangents, only with accents, and we have the following seven equations for the other seven pairs of spheres which touch S, S’, 8S”, S”, viz., P(, m, wn, p', G% 71,)=9; (29) COU 2.

In precisely the same manner as in Art. 3 we derived the equa- tions of the inscribed and exscribed circles of a plane triangle from the equations of the pairs of circles touching three circles, we can derive the equations of the eight spheres which touch the four faces of a tetrahe- dron from the equations of Arts. 18 and 19. ‘Thus the equation of the inscribed sphere is, the faces being 2, y, 2, w, derived from equation (28) 0, cos*4(ay), cos*4(xz), cos? (xv), cos’ a(yx), 0, cos’ 3(yz), cos’ 3(yw), Y cos? d(zr), cos? d(zy), 0, cos? $(sw), z|=0, (86) cos?2(wa), cos’ t(wy), cos*4Z(wz) 0, w L, Y, Z, W, 0 and the equations of the seven others are derived from equations (29)-(85). 21. Again, in the same way exactly as we derived the equations of the circles in pairs which touch three circles from the equations of the inscribed and exscribed circles of a plane triangle, we might derive the equations of the spheres in pairs which touch four spheres from the equations of the spheres touching the faces of a tetrahedron; and, in fact, it was in that way I first derived the theorem. __«-22. If we form the tangential equation corresponding to equation _ (28), we find— ) pul + vim + Aun + App + upg + ver =O0. (37) This is the condition that the pair of spheres given by equation (28) may be touched by the sphere AS + nS’ + vS”+ pS”=0. We get si- 410 milar equations from equations (29)-(35), inclusive; and since from any three of these equations we get eight systems of common values for X, #, v, p, we infer that the three pairs of spheres denoted by any three of the equations (28)-(85) are touched by eight spheres, four of which are the spheres S, S’, S”, S’”. 23. The eight tangential equations can all be included in one general formula, as follows :— Let the radii of the four spheres, S, S’, S” S’”, be denoted by r, 7’, rv’, r’, and the angle at which S intersects S’ by the notation (SS"), then we have 1 = 4r'r!’ cos? £(S'S") ; UY =— Ar'r” sin? £S'8”) ; and similar values for m, m,’ &c.

EQUATIONS OF THE CIRCLES IN PAIRS WHICH TOUCH THREE CIRCLES ONA | SPHERE. 24. The theorem, Art. 1, which was proved by inversion, can be — proved without inversion, as follows :— Let 0, 0’, O", O”, be the points of contact; A, B, C, D, the cen- tres; 7, 7’, 7”, 7/”, the radii of four circles, S, S’, S”, S”, which touch = a x ‘ All a fifth circle, =; and let G be the centre, and # the radius of =; then we have (fig. 5), AB?-(BG-AG) AB?-(r-r'p a2 L — = SE po AG: GB (R-r)(R=r') _ square of common tangent of S, S’ (Ror) (R=) Again, I 4s tAGB = = Hence, .

Hence, substituting for OO’, from (41), and making like substitutions for O” O'", &c., we have the common tangent of S, S’ by the common tangent of S”, S/’+ &., =0. 25. The proof given in the last Article is that alluded to in Art. 1; and it is evident that it may be proved in a manner precisely similar, if S, S’, S’”’, S’”, be four circles on the surface of a sphere touching a fifth circle, =, that the sin }common tangent of S, S’+sin 4 common tangent of S”, S” + sim }common tangent of S’, S’x sin }common tangent of S, S”+sin $common tangent of 8”, Sx sin$common tangent of S’, S’”=0, the common tangents being the direct or the transverse, ac- cording as the contacts of the pairs of circles to which they are drawn with = are similar or dissimilar. 26. The direct application of the theorem in the last two Articles gives at once a proof of Feuerbach’s theorem for plane triangles, and of Dr. Hart’s extension of it to spherical triangles. For if S, S’ 8”, 8S’, be the inscribed and exscribed circles of a plane triangle, the common tangent of S, S’ =b-e; 5 of 8”, S”=b+e. Hence common tangent of S, 8’ x common tangent of 8”, S’”=?-¢; and the other rectangles=¢ — a’, and a?—0b*, respectively. Hence the condition holds of S, 8’, S’””, 8”, being all touched by the same circle..— Q. E. D. 412 27. Again, if S, S', 8", S’”, be the inscribed and exscribed circles of a spherical triangle, we have Sin 4common tangent of S, S’ x sin common tangent of S’”, S’” = sin? 46 — sin? dc; and the other rectangles = sin® 4¢ — sin? $a, and sin? 4a—sin? 46, respec- tively.

Let P be the centre of a small circle S on the surface of a sphere (fig. 6); Oa fixed point also on the surface, which we shall take as origin: OX a fixed great circle, corresponding to the initial line in plane geometry; and let OP =n, the angle POX=™m, and the co- ordinates of any point Q of the circle S be p and 9, then we have from the spherical triangle OPQ, r being the radius of the circle S, cos r= {cos cos p +sin n sin p cos (O—m)} =0. (44) This may be taken as the equation of the small circle S; and itis plain that with this system of co-ordinates the result of substituting the co- ordinates of any point Qin the equation of a small circle S on the sur- face of a sphere is equal to 2cosr x sin’ the tangent from Q to S. This may be written 2cos r x sin? 4¢=8 Se SIE pp : . (459 2cosr 80.

The proofs given in Articles 12 and 14 for Dr. Hart’s exten- sion of Feuerbach’s theorem, it is evident, apply verbatim for the ana- logous theorem concerning circles on the sphere; and the part of it concerning the system of six circles, Art. 12, may also be inferred immediately from the equations (54)-(57) ; for any two of these equa- tions are sufficient to determine the ratios \: v and w:». Hence the four circles denoted by any pair of the equations (54)-(57) have a com- mon tangential circle, besides the three circles S, S’, S’’.—@. E. D. 33.

(65) 35. The equations (60)-(63) denote the eight circles tangential to three circles on the sphere, and each pair are touched by the pair of circles U= {\sinr cos (B-C) + sinr’ cos C- A) +vsinr’cos(A — B)}? (66) (See Salmon’s “‘ Geometry of Three Dimensions,’’ Second Edition, Art. 253), 416 The pair of circles (66) correspond to the circles A, A’ of Art. 14; and the circles corresponding to the pairs of circles B, BY, C,C', D, D', of the same Article are U= {r\sinr cos (B-C) + sine’ cos(C'+ A) +vsinr'cos(A+B}*?, (67) UV= {sin r cos (B+ C)+msin rv’ cos C-A +vsinr’ cos(A + B}?, (68) U = {rsinr cos (B+ C)+ mwsinr’ cos(C+ A) ; +vsinr’ cos(A-B)}*% (69) 36. It can be seen precisely in the same way as in the analogous case on the plane (Art. 6), that the points of contact of three circles, S, S', S", on the sphere with their four pairs of tangential circles are given by constructing the circles, lS mS! ns!

Again, taking any pair of the circles 8, S’, S”, the four points of contact on it with any pair of the tangential circles (50)-(53) are concyclic; the equations of the circles passing through these concyclic points are, if we denote the determinants (50)-(53) by the notation pi, P2 Ps, P53 of -0; PH =0; H=0; Wee of 0; 0; =o; cS) Ts 9; 0; Beno, (81) IV. EquATIONS OF THE ConiIcs IN PAIRS HAVING DOUBLE CONTACT WITH A GIvEN CoNIC WHICH TOUCH THREE OTHERS ALSO HAVING DOUBLE ConTACT WITH THE SAME GIVEN Conic. 88. The equations of the circles on the surface of a sphere that we have employed hitherto denote but one of the intersections of a cone with a sphere whose centre is at the vertex of the cone; thus, if a, B, y, be three such circles, then, taking account of the complete intersections of the sphere with the cones, it is evident we get three other circles, which we may denote by a, 6’, '; thus we have 8 circles touching a, B, ¥; 8 ” a, B, Y> 8 5: a, BY; 8 ” a, B, y ; hence we have 82 circles in all. The equation S— L? = 0, of a small circle on the surface of the sphere, given in Dr. Salmon’s ‘‘ Geometry of Three Dimensions,’ is the com- plete intersection of the sphere with the cone; and it is easy to see that its factors S?- £2=0 and S?:+ £=0 are the separate circles which make up the complete intersection ; in fact, taking the equation of any small circle on the sphere, Cos r - {cos n cos p + sin ” sin p cos (O—m)} =0, 418 it is by transformation to three rectangular planes changed into (a*+y°+2?)} cosr=L, where x, y, 2, are the co-ordinates of any point in the circle, and Lis the perpendicular from the same point on the plane of the great circle whose pole is the centre of the small circle ; now, this equation is of the form Si:-L=0; and it may be shown that the equation of its twin circle (see Salmon, page 200, foot note) is of the form S+iL=0, Hence the equation of the pair of circles touching three circles, a, f, y, on the surface of a sphere may be written in either of the forms ee m(Si- A) | fn (Si-N) _ cos r cos 7 Conte (a ee cos 7 cos 7’ cos r’ And it will be seen that these, when cleared of radicals, give the same result; and the equations of the other pairs of circles are got from these by properly accenting /, m, n. 39. If S’ 8”, be two small circles of the sphere (fig. 7), abed a great circle passing through their centres, and / any circle cutting them orthogonally in a’, U, c,d’; now, the anharmonic ratios of the four points, a’, 0’, c’, d’, are equal to the anharmonic ratios of the points a, 6, c, d; and two of the anharmonic ratios of the points a, ), ¢, d, are sin Zac: sindéd: sin $ab° sin ded; sin dad: sin $be: sn $ab- sinted; and these are respectively equal to Z: tan rr’: tan r’; i: tan@ : tan 7’. Hence we have the following theorem :— If any circle J cuts two small circles, S’, S”, on the sphere ortho- gonally, two of the anharmonic ratios of the four points of section are i:tanr -tanr ; lV’: tan r * tan r’; 7 0; (82) é | [7 ; | if 419 where /, 7’, are the squares of the sines of half the direct and half the transverse common tangents of S’, S”. 40. If the circles a, 6, y, be cut orthogonally by J, and denoting two of the anharmonic ratios (Art. 39) in which J intersects B, y by X, NX, J ” Yo % 5, By BK, J ? a, B I? V; ve we have {= tan r’ tan 7”, t=N tan r’ tan r/’; and substituting this value of / and corresponding values for m and nin equation (70), it becomes transformed into pee) u(Si- M1) 2 eas SE (64) sll 7 sin 7” sin 7’ and the equations of the other pairs of circles are got from this by pro- perly accenting A, p, v 41. In equation (84) it will be observed that \, u, v, are anharmonic ratios, and that sin 7, sin 7’, sin r’, are the results of substituting the co-ordinates of the poles of the great circles LZ, M, JV, in the equations S-I?=0; S-M*?=0; S-N?=0. These considerations will enable us to write down the equations of the conics in pairs having double contact with the conic S, and touching the three conics S-2?=0; S-M=0; S-WN?=0. 42. Since the equations S- Z?=0, S- M?=90, S—-WN?=0, are the same analytically as the equations of conics having double contact with a given conic, we can, by means of Arts. 40, 41, write down the equations of the conics in pairs having double contact with a given conic, and touching three others also having double contact with the same given conic. Thus, corresponding to the system of circles a, 6, y, we have the conics Si-L=0, S-M=0, §-N=0, whose common chords are (see Salmon, page 228) L—-M=0, M-N=0, N-L=0. 420 Let these chords (fig. 8) intersect in O; then from O draw pairs of tangents to the conics; then it may be proved—but I shall not occupy space in doing so—that the six points of contact, a, a’; 6b, b’; ¢, c, are in the circumference of a conic, and denoting two of the anharmonic ratios, as in Art. 40, of the points a, a, b, b’, by nr, MN; Dye OG 2 ye (Bs be; C, c, a, a, 99 V, Uae and denoting the results of substituting the co-ordinates of the poles of the chords of contact Z, UM, N, in the equations ofthe conics S — L? = S-M?=0, S-N?=0, by P, Q, &, respectively, we have from equa- tion 84 the following system of equations of pairs of conics, each conic — having double contact with S, and touching S- L’?=0, S-Mt= S- WV? =0:— HED), [FW , (FEM, oy P Q R d(S?= Z) - ee YSN) _ eee pint Non ONS (86) NO@-L) [we (St= a paGeD . | [SD -oS,-- a eae, ‘ eae + oe = 0.

Plan and restoration of St. Bridget’s House, at Faughart, county of Louth. This singular structure, which has been erected on a boss of rock near the old church of Faughart, was a simple dome-shaped stone hut or cloghaun, in plan resembling an elongated horseshoe, and measuring 12 ft. by 7 ft. 6 in. internally, the doorway, which was 2 feet in depth, being at the narrow end, and facing to the north-east. This building, of which nothing now remains but the foundations, evidently bears a close resemblance to the cell or house of St. Kevin which crowns the summit of the rocky knoll over the Reafert church at Glendalough—a structure erected by St. Kevin himself, according to the life of that saint published by the Bollandists.* In Vol. LY. of a donation similar to the present I have given a plan of the house or cloghaun of St. Gobbonet at the old church of Ballyvourney, county of Cork, “erroneously marked on the Ordnance Survey Map as ‘‘ Base of Round Tower,’’ which, though larger than that of St. Bridget, ay Re wii =a is of the same type; and in Vol. V. of the same series I give a view of the house or church of St. Finan Cam, from the Church Island, in Waterville Lake, county of Cork, which is also a structure of the clogh- aun type. It is noteworthy that, according to the six lives of St. Bridget, attri- buted to as many ancient authors s, and published by Colgan, it appears that she was born at Fochard (now Faughart), in the county of Louth, some time in the middle of the fifth century; and, after passing a life of celibacy and piety, and in 480 having founded the religious esta- blishment at Kildare, she died there about the year 523. Trish archeologists will have no hesitation in accepting the truth of the local tradition which asserts, that this stone hut was used by St. Bridget as her cell or house, and the restoration as I have given it is correct by analogy. No. 4. Base of the Round Tower at St. Endeus, or Enda, pronounced by the people on the spot Hanagh, on the Island of Arranmore, in Galway Bay. The inhabitants of the village of Killeana, which hes at the base of the rise of the hill on which this tower stood, stated that when the — tower was perfect they could see across the island to the south from the top of it, and that it was built to hold the bell of the neighbouring church. From this we are not to infer that the bell was suspended, and swung in the tower as in a campanile; but that the tower was used as the repository of this valued sacred property, amongst other appliances for which it would be suitable. My late lamented friend Dr. Petrie, for whom not one who knew him had more sincere feelings of affection than myself, told me that he recollected seeing this tower sight of about twenty feet, and that he had conversed with old p #on the island who recollected seeing it over eighty feet in height, and some of the upper opes perfect. When I visited the island in the summer of 1847, I could see but five courses of the masonry. - * See Petrie’s ‘‘ Essay on the Round Towers,” p. 424. 4295 No. 5. Interior of the window in the south wall of Kilmacduagh, or the church of St. Colman Mac Duagh at Kilmurvey, on the same island. This church was erected for St. Colman Mac Duagh by his kinsman, Guaire Aidhne, King of Connaught, about the year 610.* The flat- head of this. ope, and its “small proportions externally, are quite in keeping with other structures of this class, as well as with similar fea- ‘tures in some of our earliest Round Towers.

Interior of St. Kevin’s Church, on the southern of the Islands of Arran, called Inisheer.{ The view is taken looking under the choir arch to the doorway in the west gable. The masonry of this church is purely Etruscan, or, as it has been called, Cyclopean. The doorway is flat-headed, with converging sides; the choir arch is quite plain, but the imposts from which it springs are perfectly unique in the style of their decoration. Their ornamentation resembles a row of short drooping feathers, without the usual terminal moulding or bead. As well as I remember, this arch is semicircular, and it is interesting to find such a feature in connexion with the flat-headed Etruscan doorway. Our Lady’s Church at Glenda- lough is another example of the occurrence of the semicircular and flat arch in the same building. No. 8. Interior view of the small loop or window in the south wall of the choir ofthe same church. Without doubt, this building may date to the seventh century. No. 9.

Iknow of no better example in Ireland showing how decorative carving is mo- dified in its character by the materials used, than in thisinstance.

It is this:—The ancient epithet was Zarnairther, as may be seen from a passage in the ‘‘ Book of Inva- sions” (A. D. 856), where the expression “‘o Dun Cermna co hArainn Jarnairthir” occurs.

One side of the plinth bears a human figure standing erect, and battling with rampant animals, one on either side of him ; the device below thisI cannot unravel. Another side represents two animals like horses, with their necks and fore legs crossed, as if fighting, while two men stand by, one in the act of bending forward as if to separate the animals, andthe ~ other standing erect, enveloped inacloak. Below thisis a single hunter ~ with two dogs running before him, and each trying to catch a long-billed bird like a pelican, which 1s represented in the act of running, and not flying away from its pursuers. The third face has its upper compart- ment divided into an arcade of four arches, under two of which are hu- man figures, face to face, as if conversing; and beneath the two other — arches is a man on horseback trotting away from the conference; below this are two animais like horses facing each other, and looking down on a triquatra ornament, while over one of the horses is a human mask. It is not easy to assign a date to this work, which however, from the truncated pyramidal form of the plinth, and the shortness and plump- ness of the human figures, may very possibly date back to the tenth or _ eleventh century. No. 13. Exterior view of the east window of St. Fingin’s Church at Clonmacnoise—a building possibly of the early part of the twelfth cen- tury.* No. 14. Exterior view of the lowest ope of the Round Tower of St. Fingin’s Church, Clonmacnoise. No. 15. Do. of the second window from the basement of the same tower. Nos. 16 to 25. The following ten illustrations are taken from the sculpturings on the cross at Clonmacnoise known as that of King Fland, y according to the ‘‘Annals of the Four Masters,”’ and an inscription in the Irish character on the plinth of the cross, now unhappily defaced by | time. of The first illustration which I have selected is taken from the lowest | compartment on the east face of the cross; it represents King Fland and | the abbot Colman Conaillech, who together founded the Church of the | Kings in A.D. 909, making a compact by swearing on the cross or pas- toral staff of the saint. The costume of the king is exceedingly inte- resting; his head is covered by a flat and bordered close-fitting cap, from beneath which the hair falls behind over the shoulders in a massive club, ending ina ball; and over the ears there is a globose orna- ment, which is possibly attached to the skullcap; the moustache is heavy and plain, and the beard is long, and plaited toa point; the arms and legs are bare; and the body is clothed in a tunic which reaches no farther than above the knees, where it is bordered by a row of small disks below a zigzag ornament; a broad strap is suspended over the right shoulder, and joins on to a waistbelt, into which is thrust a —$—<——$———— * Petrie, p. 269. 427 broad and short sword with a plain crossguard, and a very massive semicircular pomell, quite resembling in outline those iron swords said fo be Danish, and which were found in the old burying ground at } Bully’s-acre near Islandbridge, Dublin. From the evidence afforded | by the sculpturings on most of our tenth, eleventh, and twelfth century decorated crosses such swords are clearly Irish, though others similar _ in shape were no doubt used by the Danes during the lengthened pe- riod they held possession of Dublin and the eastern coast of Ireland. The figure of St. Colman represents him as a young, smooth-faced. | man, attired in a round, narrow-rimmed hat ; a short cloak with a large ' hood hanging behind; a long gown reaching to the ankles, and fringed + with a row of disks between two narrow bands; and his feet are pro- __ bably bare. The cross is covered with the veilum, or scarf, and, with the staff, + reaches to the full height of the figures, which grasp it with the right and left hands alternately. No. 17. The next illustration affords a still further insight into the , regal and secular costume of that period. It represents King Fland, who can always be recognised by his broad plaited beard, standing on the _ right hand side of another king or chieftain, and joining hands with him. On this occasion the king is enveloped in a long mantle, bordered by pel- | lets, and fastened on his right breast below the shoulder by a large fibula, pierced with four circles to form a cross; the lower portion of the figure is enveloped in a long garment, reaching to the ankles, and belted : round the waist; the sword belt is thrown over the left shoulder out- side the cloak, and the sword hangs in front over the cloak, as if ready || for immediate use. The adjoining figure to the left of the king is, like | him, bare headed, with the hair curled over the ears; the moustache a is heavy, with the ends curled up, the beard is bi-forked, with the ends } curled up like those of the moustache; his dress isin all respects similar | to that of the king, but that a portion of the inner garment is looped up | im front and caught by the waistbelt, so as to form a sort of philibeg; | the sword is exterior to the cloak, and is either attached to the waist- ) belt, or held naked in the left hand, just below the crossguard—the latter ) being the most probable explanation. : It would appear that the sculptor miscalculated the length of the space to be occupied by the figures, and was obliged therefore to omit the feet of both effigies. | No. 18. This and the following four illustrations, no doubt, record _ some remarkable events in the life of King Fland, and I thus venture to explain them:— There came up the Shannon to visit the court of King Fland, at | Clonmacnoise, a wandering minstrel from Greece, or perhaps from Rome; | his special instrument was the triple flageolet, and he played before the king and his assembled courtiers; the tones which he produced by much | physical effort, as his inflated cheeks and swollen eyes attest, though . pleasing to himself, were by no means appreciated by the Irish audience; | and the witty sculptor, while he recorded the remarkable fact of the ad- 428 vent of the foreigner, satirized his performance by likening it tothe squall- ing of two cats tied together by the hind legs and tails; while the lower notes of the fiageolet resembled such unheard-of tones as might be pro- duced by a learned animal of the canine species, if he could convert his ~ own body into a bagpipe, and make his tail the chanter. The dress of © the musician is quite unlike any costume I have seen on any of our © sculptured crosses ; it consists of a simple long robe, reaching to the feet which are bare; the sleeves very wide at the elbow, but closely confined ~ at the wrists; the hair is divided at the forehead, and falls long and straight down the back from one shoulder to the other. ¥ No. 19. It would appear that at this time the court of King Fland was graced by the presence of a female harpist of much grace and ~ beauty; she is here represented as seated with her harp on her knee; she is clothed in a long flowing dress, reaching to the ankles, and a short cloak, the hood of which is modestly brought round the face, and hangs in a graceful curve down her back. Her performance must have been of the highest order, and the whole expression of the figure conveys the idea that the last chord of some thrilling melody has just been struck, and the performer looks round for the accustomed applause. So effec- tive were the melodies of the harpist, that the spirit of ennus and discord, | typified by a crouching big-headed, horned monster, with its tail abjectly rolled up along its fianks, is placed beneath this figure which tramples upon it. Mi No. 20. In the compartment over the harpist we have another effigy | of St. Colman, but seated, as forming one of the audience at the court | concert; his right hand grasps a short cambutta, or pastoral staff, witha | crooked head; a short scolloped mantle envelopes his shoulders, and di- — rectly over his head is a cherubim with expanded wings. fies In this sculpturing, I think, we have expressed the delight of Si) Colman at the performances of the female minstrel, which to his poy | etic imagination resembled the voices of an angelic choir. Here I must pause for a moment, to remark that till I saw this mal sculpturing I had but little respect for a cherubim, as I classed it with the cingue cento and Rococo ornaments of the Elizabethan era: here, — however, we can trace its pedigree back to the ninth or tenth century, — and we find it associated at that time with the saints and magnates of the land. No. 21. In this sculpturing we have St. Colman seated in an arm chair: in his right hand he holds hislarge cross, and with the end of it he strikes the face of a prostrate figure, “apparently clothed in no other garment than ashort mantle. Can this represent the punishment or ex- | pulsion of some offender from the court of King Fland? for the scene is | too circumstantial to be merely allegorical. | No. 22. Here we again see King Fland and his companion (as illus- | trated in Fig. 17), each being identified, the one by his plaited beard, and | the other by his heavy curled-up moustache. St. Colman is seated | between them in conclave, as if urging them on to some joint mode of | action; in his right hand the saint holds the short cambutta with the | 429 erutch head, formed by a double crook which appears to have been the third kind of ecclesiastical staff used by the early Irish bishops, and of which we find many examples on our sculptured crosses and illuminated MSS. ; this he holds towards the figure opposite King Fland, who grasps it with hisright hand, the saint extending his left hand to the king, and presenting to him something like a small box; but this portion of the carving is very obscure. ; In the foregoing two illustrations we no doubt have representations of _ some remarkable event in the life of King Fland. No. 23. This sculpturing appears to represent the guarding of the se- pulchre, and the ascent of our Lord—the Roman soldiers being, of course, _ dressed in the costume and with the arms of the Irish gallowglass of the ninth and tenth centuries; these consist of a conical helmet, a short stout spear, a belted tunic reaching to just above the knees, the arms - and legs being bare; neither figure is bearded, though the moustache is worn, which may either imply that the men were young, or that the beard was not allowed to the common soldier, which is, I think, the most correct explanation. Over the head of the small central figure is the nambus, and above it a circle with a descending dove within it, typifying the Holy Spirit; and to this subject I shall presently return. No. 24. This sculpturing is obscure in its meaning, and is merely _ given as affording another example of the arms and costume of the gal- _lowglass, which agree with that just noticed. No. 25. Sculpturing on the soffit of the circle of the cross; it re- presents two human masks inclosed by two serpents wound together in _ an §-shape form; and it is quite evident that the sculptor drew on his imagination for the figures of the serpents, as he appended ears to them like those of a ruminant, and a spreading fantail like that of the salmon -and perch. Above this device is an extended hand, coupé at the wrist, and surrounded by a circle, decorated, like the bodies of the serpents, with a row of small disks. I have seen it stated that in the Greek or Eastern Church the bishop gives the benediction by extending the outstretched hand. Can we suppose, therefore, that the outstretched hand in this as well as in other | similar examples is emblematic of the benediction bestowed on the eross when it left the hands of the sculptor ? No. 26. The sketch on the right hand side of this sheet represents the dove and nimbus, described as surmounting the head of our Lord /in the sculpturing numbered 23; and to this feature I wish to direct your special attention, inasmuch as I believe that here we have the / original idea which suggested the cross formed by the intersection of four parts of circles, or the cross of eight points which is essentially both Irish and Greek. By the side of this figure I give the cross derivable from it, and which I propose to call the dove cross. | In the following illustration, No. 27, this cross, in combination with that having straight arms, gives us the typical form of the Irish stan- | dard cross. R. I, A, PROC.—YOL. IX. 31 430 On the tombstone of Luguaedon Mac Clmenueh, the nephew of St. Patrick, figured by Dr. Petrie in his work on the Round Towers, this fanning or spreading out of the arms of the crossis expressed by the bi- furcation of the straight arms of the cross. On many of our early ogham pillar stones we have the cross of eight points, and we possess an instance of this kind in our own collection of antiquities.* In such standard crosses as that of St. Nen, or Nenidius, on Inishmacsaint Island in Lough Erne, figured in Vol. II.. of this series, we have this form of cross, but without the circle or aureole, which was not essen- tialin its true character. When, however, the dove crossis surrounded by the aureole or circle, with the straight-armed or Latin cross project-_ 4 Sa et oe ing beyond it, as in Fig. 27, the cross attains its full development, and typifies the Divinity as well as the humanity of our Lord. T had long sought for the origin of the cross and circle, as seen on our monuments, and I believe that I have found it in the figure of the outstretched dove from the cross of Clonmacnoise. No. 28. The dove is frequently sculptured on our decorated crosses, as emblematic of the Holy Spirit. Thus, in the example now given, from the shaft of the headless cross in the graveyard at Kells, im the county of Meath, which represents the baptism of Christ, the bird ap- pears in the act of alighting on one of the bulbs of the water lily placed beneath the male figure as emblematic of river water. Nos. 29, 30, 31. Ancient tomb slabs from Clonmacnoise; the church- yard of Kells, county of Meath; and the old abbey in the demesne of Castle Archdallin the county of Fermanagh.

No. 32. View of the stone-covered holy well called Tobar- na- Dra oo (Well of the Druidess), + or Clon Tubrid (Retreat of the Well), in the county of Kilkenny, from a sketch kindly supplied to me by the Rev. | James Graves.

Carved stone at or near to the holy well just named, and which is also taken from a sketch by the Rev. James Graves; this re- presents a female figure enveloped in a long mantle; the effigy is im high relief from the stone, which is carved around it into a heart-shaped form, with a broad and raised border. It is remarkable that this is the third example I have found of a heart-shaped stone being connected with early ecclesiastical remains—one is at the old church of St. Mologga, * See Vol. I. of this series. +N.

And the third I have already illustrated in connexion with the details of the old church of Kilmalkedar in the county of Kerry, Vol. V. of this series. The occurrence of stones carved in this peculiar form in places so remote from each other is somewhat remarkable, and there must have been some peculiar meaning attached to them, with which we | areat present not acquainted. At Kilmalkedar I was informed that this | heart-shaped stone was originally placed on the apex of the west gable, and that it was thrown down in a storm; it is quite possible that this was the original purpose for which these stones were intended, and, if so, we have discovered the correct device for the completion of the west gable of churches up to the early part of the twelfth century at least, a point in early Irish ecclesiastical architecture hitherto undefined. No. 35. Exterior view of the doorway of the old church of Clona- mery, or Killamery in the county of Kilkenny, from a sketch by the Rey. James Graves. This doorway, which is flat-headed, with converg- ing sides, is strictly Etruscan in its style of masonry; it is surrounded by araised broad flat band, which does not appear to have been completed down the lower half of the southern jamb of the door; from the upper | part of this band, where it crosses the lintel, a broad flat moulding pro- | jects vertically across the lintel, and joins on to a cross of eight points (the dove cross), also flat, but in relief, and carved on the adjoining stone. | From the general similarity of this doorway to that of the old } church of St. Fechin’s at Fore, in the county of Westmeath, figured in | Vol. VI. of this series, and also to that of the Round Tower of Lusk, in the county of Dublin,* we are safe in assigning the date of this doorway to the seventh or eighth century.

All the win- dow casings, as well as the quoins of the main building, are of cale tufa—a material sometimes used in the construction of twelfth and thirteenth century churches, as in the roof of Cormac’s Chapel at Cashel. This stone, from its porosity, is remarkably light, and from its exposed position at this locality is externally decayed, though singularly sound, all circumstances considered. No. 46.

The form of the outer portion of the door is ~ essentially ancient, while the surrounding moulding, with the surmount- ing semicircular arch, is clearly in the style of the thirteenth century. ~ We have now no means of judging what was the exact character of the — external arch; it was, however, formed of stones not bonded into the — masonry of the gable, and in this respect resembled the arch over the — doorway ofthe Round Tower of Dromiskin, near Dundalk.| We know, | | however, that the arch was decorated round its outer margin by five hu- man heads, four of which are still 7m situ, the fifth being placed over St. | Edan’s Well, opposite to the present parish church of Ferns.

ANGLO-NORMAN ANTIQUITIES AND ARCHITECTURE. No. 52. Effigy in chain mail from the nave of Christ Church Cathe- } dral, Dublin. Till lately this knightly effigy was supposed to be that | of De Clare, Earl Strongbow, who died at the close of the twelfth cen- | tury; but, as I have long ere this stated, the occurrence here of the » rowelled spur is strong evidence against its being a work of the twelfth } century, the earliest example of a spur of this form, according to | Planché, being first observed on the seal of Henry III., 1216.} _ The Rev. James Graves, in a most admirable memoir on this effigy, lately ‘published in ‘‘The Gentleman’s Magazine,” has shown con- clusively that the coat of arms displayed on the shield of this effigy, yiz., in chief, three crosses, pattee, fitchée, are not those of the De Clare family, Karls of Pembroke, their arms being either three chevrons, or chevronée. Which of the Norman knights is here pourtrayed has therefore yet to be determined.

This is evidently a work of the twelfth century atthe latest, as is proved by the presence of the spike spur, which is not fastened to the heel, but strapped round the ankle. The form of the - crossguard of the sword is also twelfth century; and it is singular that the figure is accoutred without a scabbard. The form of the hel- met is obscure, owing to the upper portion of the head having been _ broken away. ‘The body is clothed in a surcoat reaching to below the Es knee in massive plaits, the waist is belted. The saddle is peaked in front and rear, reaching high above the waistbelt; the shoulders and the greater part of the neck of the horse are protected by a thick tight-fitting covering, fastened to the bow of the saddle, the forehead of } | the animal being guarded by a rectangular plate of metal, apparently fastened to an inner neck-and-headguard, passing beneath the shoulder _ armour just described. ‘There is the appearance of a bit in the horse’s o mouth ; and the bridle, which is represented as single, passes beneath the —_ neck armour. It is probable that this sculpturing formed a portion of a tomb erected to one of the Irish chieftains who fell in battle against the English invaders, or an equally hated neighbouring chieftain, asif- is not at all probable that an English or Anglo-Norman knight would have acquired such a social standing as this tomb would indicate in such a remote district as this to the west of Tralee, at the close of the | twelfth century.* No. 55. Effigy of St. Christopher, from a carving in high relief on i limestone, preserved, when I saw it, in the Pilltown Museum, and stated | to have been taken from Jerpoint Abbey. Thesaintishere represented | as standing in the water, leaning on his budding staff, which is grasped in his right hand, while he bears the infant Saviour on his left arm and | shoulder; the water is expressed by zigzag lines crossing his legs, and | the lower end of the staff; and also by the outline of a fish on the field | of the stone to the left of the figure. The cap of St. Christopher, which has a low round crown and a broad upright rim, is the only characte- ristic feature in the costume, and it fixes the date by the carving at the - @ thirteenth century. St. Christopher’s hair falls in flowing curls over | his shoulders; his face is without the moustache, but he wears a care- | fully curled beard beneath his shaven chin. His body is clothed in a long-sleeved garment, the ends of which are looped up, and thrown over his left arm; beneath this is a loose tunic reaching to the knees. The bead of the infant Saviour is surrounded by the nimbus: and his right hand and arm are raised in the act of giving the benediction to St. Chris- oI topher. The legend of St. Christopher is one of exceeding quaintness, and contains a sound moral; and, as it is not generally known, I venture to * See notice of this effigy in the “‘ Kilkenny Archeological Journal,” vol. il. “ae * ae 1853, p. 39, by Richard Hitchcock, Esq. oh 435 give its leading facts, extracted from an admirable paper on this sub- ject by Messrs. Dennet and Barton, of the Isle of Wight, and published in “The Archelogical Association Journal” for August, 1847, as explana- tory of a mural painting discovered atShorewell Church in April, 1847. The authors take for their authority Caxton’s edition of ‘‘ The Golden Legend,” printed in the year 1483, and translated by him from Jacobus de Voragine. «< St. Christopher was of right great stature, with a terrible and fear- ful countenance, and he was twelve cubits in length. He was in the ser- vice of the king, but it came into his mind that he would seek the greatest prince, and him only would he obey.” Accordingly, he travels till he comes to one sovereign who is renowned as the greatest in the world ; in his service he stays till upon a time a minstrel ‘‘ song to fore him a song in which he named the devil oft ;”’ and the king, which was a Christian man, when he heard him name the devil, made anon the sign of the cross. Christopher asks the reason of this; and, on learning that it was to protect him from the power of evil, concludes that the devil is mightier far than the king, whom he therefore leaves, ‘saying, ‘I will go to search him [the devil] to be my lord, and him will I serve.” In journeying over the desert he meets a great company of knights; and one of them, with a cruel and horrible countenance, tells him that he is the power he seeks. They journey on till they come to a eross; and the devil, in sore affright, leaves the direct road in which it | stands. This excites Christopher’s curiosity, who, discovering the ¢rue reason for this fear, exclaims, ‘‘I have laboured in vain; I will serve thee no longer, for I will go seek Jesus Christ.” He travels then into a desert, and meets a hermit, who instructs him in Christianity, and ultimately places him beside a rapid river, where many perish who try to cross it, to bear over travellers harm- less,. because he is of gigantic stature and strength. Christopher then _ bare a great pole in his hand, instead of a staff, by which he sustained him in the water; and bare over all manner of people without ceasing. One night, as he slept on his bed, he heard the voice of a child calling him. Then Christopher ‘‘lyft up the child on his shoulders, and took his staff, and entered into the ryver for to passe;’’? and the water of the river rose more and more, and the child was heavy as lead; and alway he went further, the water increased, and the child more and more waxed heavy, so that Christopher had great anguish, and was afraid to be drowned.’”’ When he had escaped to the other side, he set the child aground, and said, ‘‘ Thou hast put mein great peril; _ thou wast almost as I had all the world upon me.” And the child answered, ‘“‘Thou hast not only borne all the world, but thou hast | borne Him that made all the world, upon thy shoulders. I am the Christe the King, to whom thou servest in thy worke.”’ And, as a token of the truth, he tells him that, if he sets his staff in the earth by | his house, it shall grow; and when he arose in the morning, he found his staff like a palmyer tree, bearing flowers, leaves, and dates. 436 Christopher now travels to Lycia, and converts many by the exhi- bition of this miracle, until the king condemns him to death. He was accordingly bound to a strong stake, and forty archers were ordered to ‘‘ shotten him through with arrows.’ None of the knights, however, might attain him; for the arrows hung in the air around him. Then the king, thinking that he had been executed, went towards him, when one of the arrows turned suddenly in the air, and smote him in the eye, and blinded him. Christopher tells him he may recover his sight by mixing his blood with clay, which, after the decapitation of the saint, he does, and recovers, The writers go on to say that figures of St. Christopher are not uncommon, either painted on the walls or on glass, in churches. It was a popular superstition, common to all Catholic countries, which induced people to believe that the day on which they should see a figure of this saint they should neither meet with a violent death, nor die without confession... The Squire, in Chaucer’s ‘‘ Canterbury Tale,” wore ‘‘a christofre on his breast of silver sheen,’ for the same reason. At the lower compartment of the fresco painting, on the right side, St. Christopher is represented as alive, and bound naked to his own staff, which resembles a budding tree; and his body and legs are pierced with innumerable arrows, shot by two archers, who stand one at either side of him. This is one way of illustrating the miracle that he was not killed by being so pierced. In the distance the king is seen | standing looking on at the execution, attended by his sword-bearer and hawker; and one of the arrows is represented as striking him in the eye. In the year 1847 I visited Knockmoy Abbey, in the county of Galway, and sketched the fresco painting on the north wall of the chancel, which is familiar to all Irish archeologists, and to which allusion is made in ‘‘The Dublin Penny Journal;” and in a short memoir, by the Rev. Dr. Todd and Professor O’Curry, in the ‘‘ Pro- ceedings of the Academy” (vol. vi., p. 8); and, lastly, in the first volume of Sir W. Wilde’s ‘‘Catalogue of the Academy Museum ”’ . old). 4 oe compartment of this fresco painting represents a living naked figure bound to a palm tree, and pierced in the body and legs with many arrows, shot by two archers, one at either side. In the Catalogue of the Academy this painting is called the Martyrdom of St. Sebastian | —an idea which is merely a repetition of a previously expressed opinion of Dr. Todd, who, in conjunction with Mr. O’Curry, detected the date (1400) in a black letter inscription on a portion of the painting alluded to. Any one conversant with the costume prevalent during the reign of Richard I1.—1377 to 13899—would assign the date of the fresco paint- ing to the close of the fourteenth century—an idea happily confirmed by the discovery of the date upon it. With all respect to the two high authorities just named, I must dis- agree with them in believing that the Knockmoy figure represents the martyrdom of St. Sebastian. Without doubt it represents the martyr- 437 dom of St. Christopher, as is almost proved by the fact that the figure is represented as alive, and bound to a budding tree, the miraculous staff of the saint. In all the representations of the martyrdom of St. Sebastian which I have seen, the figure is represented as in the last gasp of life, and seated on the sround, or in the act of falling from a standing position. Dr. Todd, in the notice alluded to, states that the name of St. Sebastian does not occur in the Martyrology of “The Four Masters.” From the foregoing remarks, I think, we may safely conclude that the martyrdom of St. Christopher is the subject of the lower compart- ment of the Knockmoy fresco. No. 56. Inscription in Anglo-Norman letters, from the wall of the episcopal castle of Fethard, in the county of Wexford, drawn to the full size. My friend the Rev. James Graves, to whom I am indebted for having brought me to see this inscription, sent me a sketch of it in the year 1863, informing me at the same time that a sculptured cross, stand- ing in the courtyard of Carerew Castle, in Pembrokeshire, bore an in- scription so similar to this as to lead to the belief that they must have been copied from the same MS. transcript. He stated that it never had been deciphered, and asked a reading of it. I believe it may be translated as follows :— Mas: (contracted): ‘‘Magistére,” or the major domo of the castle. Oic : Lies €c1 : (phonetic) Here. Cpe: (contracted): Tréfoncier. The proprietor of the estate. Cec : This. C : Tombstone. f&: Fecit, or Fecerunt. This reading attempts the solution of a problem hitherto unsolved, and would be accepted by some of my antiquarian friends if I could account for the occurrence of a similar inscription on the Carerew cross. This I think is not just, as I have nothing to say to the cross in ques- tion, and know not what connexion there existed between the Anglo- Norman proprietor of the domain of Fethard in the twelfth or thirteenth century, the supposed date of the inscription, and the owner of Carerew Castle at the same period. No. 57. Inscription in debased Anglo-Norman characters, from a slab set into the south sidewall of the chancel of Christ Church Cathe- dral, Dublin. It is remarkable that, though each letter of this inscrip- tion is perfect, and each word defined by three dots, no person to whom have submitted it has attempted to read more of it than is evident to any one. I doubt that it is older than the sixteenth century, from the form of the letters A. N. and T., and the frequent joining together of the letters A. M. and A. R., whichis so characteristic of the period to which T allude. The name Ion .. Luaparp is very plain at the beginning of the in- ‘eription, and the second line comprises the words DE : PARME; & : R. I. A. PROC.—-VOL, IX. 3M 458 DAME : RAME : PERIS : followed by pz : sEIDT : sAvMDVR ? whichin sound resembles de Saint Saviour, the last words being MURUNT : GIEINT : 1011, possibly meaning having died, lies here. The last four letters are obscure; for they could not possibly represent the date 1011 in Arabic numerals. The Rey. James Graves thinks the inscription is in Italian, which is quite possible. No. 58. View of the Anglo-Norman tower erected at the extremity of the Hook promontory, county of Wexford. This magnificent structure has been converted into a lighthouse, by the addition of a small circular turret, surmounted by the lantern—a purpose for which I have very little doubt the tower itself was origi- nally constructed. The main tower, which is about 70 feet in height, is circular with- out, but square within, the intervening spaces being occupied by a winding staircase, and small rectangular rooms leading off the central vaulted apartments. It is stated that De Courcy was the builder of. this tower. All history and traditions assert that Karl De Clare or Strongbow landed in 1170 or so, on the shore of the Waterford estuary, and ac- cording to the latest authorities, at Crook, opposite to Duncannon. To the north of Hook, at Bag-in-bun Head, an earthen fosse and — mound, which span the promontory from shore to shore, are pointed out as the site of Strongbow’s entrenchment, and a rectangular depression in the sod, the place where his tent was pitched. I have no doubt that this spot was occupied by the Anglo-Normans at the time of their inva- sion, who found there an ancient Irish entrenchment, which they utilized ; but it certainly is not the place where any landing of troops could be effected, as the entire coast is here rocky and precipitous.* No. 59.

This castle was erected in the year 1300 by the Knights Templars, just four years be- fore the suppression of the order by Edward I. In plan it is a simple parallelogram, with walls of six or seven feet in thickness, sufficient to | receive fireplaces, and recessed loopholes. A massive square tower | of two arched rooms projects from the south wall, which is so far pro- | longed beyond the face of the east wall as to form a small flanking, | turret. The centre of the east wall is further protected by a small pro- |” jecting angular tower. The archeres, or loops, for either long or cross | bow are remarkably characteristic of the Edwardian architecture, as | are also the flat-pointed arch and flat-compressed arch of the various in- | * The small expedition, consisting of five Welsh vessels, headed by Robert Fitz Ste- | phen, landed, according to Giraldus Cambrensis, at Bannow Island in A. D. 1169, prior | to the arrival of De Clare with the main army, 439 ternal recesses. The wall was probably never much over fifteen or eighteen feet in height; but the tower, or keep, may have reached to thirty feet, or more. In the “‘ Dictionary of Military Architecture of the Middle Ages in France,” by M. Violet le Duc, he shows that massive wooden struc- tures entered largely into the construction of the castles of the thirteenth, fourteenth, and fifteenth centuries, not only in the interior of such walls as those forming Ballymoon Castle, but along their summits. With- out doubt, this effective mode of defence was adopted here after the most approved fashion; for the low walls of Ballymoon could offer but feeble obstruction to any determined escalade. The wall defences, there- fore, probably consisted of a wide projecting covered gallery, resting on massive beams placed transverse to the wall, and called hoarding, thus making every portion of the wall impregnable to all modes of attack except that of fire, which the garrison, no doubt, knew how to resist.* That our medieval castles were thus protected by external wood work, forming galleries round the summit of the walls, is clearly proved at Trim Castle, where, two years since, I detected the ends of mas- sive oak beams, broken short off, and filling large external putlock holes which surround the summit of the keep in two regular rows, far apart, the lower being for the struts, and the upper for the flooring of the galleries. Thus we can understand the peculiar form of many castles, turrets, and walls, illustrated by Froissart, in his Chronicles, which before were not easy of comprehension, supposing the structures to have been en- tirely of stone. No. 64. Effigy of a bishop, or mitred abbot, preserved in the wall of the courtyard of Slane Castle, county of Meath. From the rudeness of the sculpturing, and the absence of all details in the dress, with the exception of the large finger ring on the right hand, which is raised in giving the benediction, I should regard this as late fourteenth century, or possibly fifteenth century work. No. 65. Plan of Clonmines Abbey, county of Wexford. From this it appears that originally the arch of the central tower was lighted on the south side by a beautiful window of three opes; subsequently this was built up, and a winding stairs constructed within it, which led to the summit of the tower. It is not easy to determine whether this change in the original plan of the building was made to strengthen the tower, or to add to it as a means of defence—possibly both. + No. 66.

In the year 1862, when [I last visited New Ross, every stone of the gateway was gone ; and it is therefore possible that of this ancient gateway there exists but this sketch to show what it was in later years. No. 80. View of Dean’s Castle, near Carrick in Bannow, county of Wexford. This graceful rectangular tower, of unusual height, was originally much more lofty than it appears at present, as is evident from the brackets to support the bartizan, or eschanguette, to protect the doorway, being yet preserved at what is now the summit level of the walls.

From the occurrence of large circular brackets, such as would sup- port small turrets, at the north-east and north-west angle of the wall of the principal building, and which are about fifteen feet from the ground, it is probable that the northern side of the second floor was entirely constructed of wood, in the form of a gallery, to defend this side of the castle. | No. 97.

In the foregoing Catalogue to accompany the seventh Volume of my Antiquarian Sketches, which I have had the honour to present to the ’ Library of the Academy, I have not attempted to investigate the histo- vical facts relating to the various objects I have sketched, from want of time for such a purpose. These Sketches are the product of my leisure | hours, and their defects, which are very apparent, will I trust be over- ! looked when the object which I have in view is understood—that of | endeavouring, as far as my unaided efforts will allow me, to record in truthful outline many an object of antiquarian interest, which in my own memory has ceased to be, or which will disappear in a few more | * years. In conclusion, I wish in justice to myself to reply to some unjust | criticisms openly passed on this collection of Drawings when they were _ exhibited and presented to the Library of the Royal Irish Academy on | the 9th of April last, and when I was not present to answer or explain. | Istate distinctly that all my drawings of antiquities in this and the * See sketch of the tombstone of the Hackets from Morne Abbey, south a Mallow, _ county of Cork, Vol. III. of this series. A44 other six volumes are taken from original sketches made by myself, with but very few exceptions, and then I name my authorities; andif — T sometimes illustrate anew what has already been published, I know that I thereby correct an error, and do good service to the cause of an- — tiquarian truth.

Mr. AtexanpEer Macatister, Demonstrator of Anatomy, Royal Col- lege of Surgeons, Ireland, read the following paper :— Nores on Muscunar ANOMALIES IN Human ANATOMY. Te rapid advances which have been made of late years in the know- ledge of comparative and embryological anatomy and their kindred sciences have given a stimulus to our researches after muscular irregu- larities in the human subject, as in these we frequently find the clue to the explanation of the varying positions and modes of arrangement of normal muscles, both in man and other animals. Although Huxley and Wood in this country, and Henle, Theile, Kelch, Hyrtl, and Meckel on the Continent, have written much on this subject, yet such is the variability of the human frame, and of so frequent occurrence are novel irregularities, that it often falls to the lot of other observers to examine specimens which have not as yet been placed on record. For the past | eight years, during which time I have been connected with the anato-* mical room of the Royal College of Surgeons, I have preserved notes of all the more important deviations from the normal types which I have observed, and of these there are some which, to my knowledge, have not been as yet made public. As it seems to be a law of nature that the complex types of organi- zation are much more liable to irregularity than the simpler forms, so we should expect to find the human structures more disposed to abnor- mal modes of arrangement than the parts of other Vertebrates; and such, indeed, seems to be the case. Whether these irregularities are connected with corresponding varieties of vital individuality, it is usually impossi- 445 ble to determine, and concerning the causes which bear on their production we know little. I have: found them more commonly on the - right side than on the left, and in females more frequently than in males. The influence of sex in determining the occurrence of anomalies is probably, however, very slight; for thoush in my notes I find that a - considerable preponderance of the cases occurred in females (as a greater | number of individuals of this sex are submitted to our observation in the . dissecting room), yet others have remarked the contrary ; and:it is proba- | ble that, ‘had we asutiicient body of evidence, we would find the numbers | tolerably equal in both sexes. I can in general concur fully with the introductory remarks of Mr. Wood, in his admirable papers on this sub- ~ _ ject, in the ‘‘ Proceedings of the Royal Society” for 1865. The varieties which I am about to notice may be arranged into six elasses :— Ist. Such as arise from the presence of muscles not typical parts of the human frame; 2nd. Variations of normal muscles by duplicity, either in whole or in part ; 8rd. Variations of normal muscles by complexity or alterations of attachment, of course, or of arrangement; 4th. Variations by the coalescence or union of muscles normally separate ; 5th. Variations by segmentation, or the fission of muscles into several parts ; 6th. Variation by suppression, either partial or complete. This arrangement, it will be seen, is an extended modification of that adopted by Mr. Wood, and for practical purposes will be found extremely convenient. I. The first, and most interesting group of anomalies iene all those muscles which are occasionally present, as if by accident, in man, although not normal constituents of the human frame, either in rudi- ment or in perfection. Most, if not all, of these are natural elements existing in lower animals; and when they occur in man, they are usu ally unconnected with his normal muscles. In some of the instances in which I have noted them, they were gregarious in their occurrence, two or more anomalies of this class being present in the same individual, and in the majority of instances they were symmetrical. The following are the principal varieties of this class which I have observed :— 1. Sternalis rectus I have seen many times, varying in its degree of development, from a few vertical fibres or tendinous bands running in front of the sternum, either from the sternal tendon of the sterno- mastoid, or from the manubrium, to its full perfection, as a large fleshy mass, separate from both rectus abdominis and sterno-cleido- mastoid. Et. A. PROC.—vVOL. IX, oN 446 In one instance it was double; but in all other cases it was single, and on the right side. Its usual attachments, in six or seven instances, I have found to be from the inferior border of the manubrium sterni to the upper margin of the fourth, fifth, and sixth costal cartilages, and in none of the cases where it was lar ge and fleshy was it connected with the sterno-mastoid. Its length varied from three to six inches, and its breadth from half an inch to twoinches. In one instance its tendon of origin was an inch and three-quarters in length; but I have never detected tendinous intersections in its belly, as described by Meckel; it always overlay the great pectoral, and often coexisted with other ano- malies. The nature of this muscle as a thoracic representative of the rectus has been clearly shown by Theile and Meckel. 2. Cephalo-pharyngeus externus of Theile, or at least a somewhat corresponding muscle (Plate VI., fig. 1, 6) I found in one instance aris- ing from the inner and posterior extr emity of the vaginal process of the temporal bone, and from the rough inner angle of the petrous portion, external to the first attachment. of the superior constrictor of the pha- rynx. It ran downwards and inwards, parallel, but internal, to the stylo-pharyngeus, and was inserted into the mucous membrane of the pharynx, passing between the middle and superior constrictors. This might be a modification of the true salpingo-pharyngeus muscle of Hailer and Cruveilhier, but in my case it had no connexion with the Eustachian tube. 8. Another small pharyngeal muscle, similar to that named by Meckel the azygos pharyngei, I have found on several occasions (Plate VL., fig. 1, a), arising from the central spine, on the basilar process of the occipital bone; and, being inserted into the raphe of the pharynx, superficial to the insertion of the superior and middle constrictors; with the ascending fibres of the latter muscle it is often confounded. It is present in the pharynx of several Mammals, and is commoner in them than some imagine. 4. An additional scalenus muscle has been described by Albinus and Meckel as an occasional development in the neck. The former author has named it scalenus minimus, and in some instances this organ has been found cleft into two distinct parts, internal and external. It arises from the first rib, and is attached to the anterior tubercles of the transverse processes of the fifth, sixth, and seventh cervical vertebre; it usually passes between the subclavian vessels and the lower cervical nerves. In one instance in which I found this muscle to exist, it was further complicated by the total suppression of the scalenus anticus; but they not unfrequently coexist, and in seven subjects selected at random in the dissecting room this muscle existed symmetrically in three. 5. I have likewise been able to demonstrate most distinctly in one case the presence of a fifth scalene muscle (Plate VL., fig. 2, b), situated under cover of the scalenus medius. This structure was much stronger than the normal scalenus anticus, and was inserted above into the pos- terior tubercles of the transverse processes of the fourth, fifth, and sixth cervical vertebre, and arose from the first rib below, at the anterior bor- SE Eo = 447 _ der of its tubercle, within and behind the insertion of scalenus medius, | from which, part of the upper roots of the brachial plexus and a plane - of cellular tissue separated it. The insertion of the scalenus medius in _ this instance was extended farther upwards than usual, and was connected with the posterior tubercles of the transverse processes of the first, se- cond, and third cervical vertebrae. The scalenus posticus was normal. To the above described muscle perhaps the name scalenus accessorius | might be given. JI have found it present in some of the Quadrumana. 6, An unimportant, though distinct muscle, for which I would sug- gest the name rhombo-axoid (Plate V., fig. 1, a), I found in one sub- | ject, arising from the spinous process of the seventh cervical vertebra, _ underneath the rhomboideus minor, and closely connected to its origin. _ Its fibres ran upwards, forwards, and outwards, in a round fasciculus, and, becoming tendinous, were inserted into the transverse process of _ the atlas. This band lay first on the serratus posticus superior, and then _ onthe splenius colli. 7. LI have very frequently found in man a small muscular slip (subscapulo-capsular, mzhz), to which the name infraspinatus secundus _ has been given by Professor Haughton (Plate VIL, fig. 2, a). When present, it arises from the anterior aspect of the axillary border of | the scapula, immediately below its neck, usually overlapped by the subscapular muscle, and anterior to the origin of the long head of the triceps; from this it passes outwards, and is inserted into the inferior and anterior part of the capsular ligament of the shoulder joint. I have found this muscle either quite separate from the subscapularis, or else conjoined withits lower border. Among the Mammalia I have seen it in the horse, seal, and many others ; and Professor Haughton has kindly informed me that he has found it present in several of the larger Qua- drumana, in some of which it was particularly welldeveloped, especially in Macacus nemestrinus. In the majority of cases among animals this muscle has little or no connexion with the capsular ligament, but it is usually inserted into a point intermediate between the posterior surface of the lesser tuberosity and the inner lip of the bicipital groove. The human muscle would thus seem to have a special action to make tense the cap- sular ligament, and to prevent its being pinched in rapid motions of the joint; it is probably the upper extremity representative of the gluteus quartus of Mayer and Haughton. 8. Coraco-capsular is a small muscle described by Mr. Wood, which T have rarely found present: in the few instances in which it has occurred, it arose under cover of the coraco-brachialis from the under side of the extremity of the process, and was inserted into the upper and anterior part of the capsule. It sometimes seemed as it were an offshoot from the coraco-brachialis, but more commonly when present it is distinct. I have found it existing and very distinct in Cebus and Callithrix; and in these it usually passes completely over the capsular hgament, to be attached to the front of the neck of the humerus. From its origin and from the relation of its insertion tothe capsule and to the lesser tuberosity, it might perhaps be considered as the humeral homotype of the qua- 443 dratus femoris. This and the foregoing are functionally analogical, as they are both tensors of the capsular ligament. Gantzer has described a third muscle, with a similar action, passing from the cartilage of the first rib to the same destination under cover of the lesser pectoral. 9. Extensor primi internodu pollicis et indicis of Wood I found in one subject, in 1858, arising from the ulna below the extensor secundi internodu pollicis, and above the extensor indicis, the tendon of which latter muscle united with the indicial slip of the anomalous extensor, aud was inserted ito the second and third phalanges of the index finger. This muscle exists in the dog and fox. 10. An extensor annularis proprius, which may be regarded as a rudiment of an extensor digitorum brevis manus, I found in the left hand ofa female subject, arising from the dorsal aspect of the cuneiform bone and annular ligament and heads of the fourth and fifth metacarpal bones. The muscle extended forwards; and ended in a single tendon, which was inserted into the inner side of the long extensor tendon of the ring finger, about the base of its first phalanx. Another rudiment of the short extensor of the fingers I found in a male hand, similar to the foregoing, but passing to the middle finger only, and quite separate from the interossei. Not unfrequently I have seen the dorsal interossei sending off slips, which seemed as though representatives of the same extensor muscle. 11. In this class of irregularities I would place several instances of double interossei in the hand, which | have at different times observed, both involving the palmar and dorsal groups of muscles. The former I have found doubled in four different subjects—the latter in one instance. tn this case there were two muscles lying in each inter-metacarpal space, each inserted by a tendon into the corresponding side of the finger. (This instance is reported in ‘‘ The Medical Press,”’ vol. i1., p. 413.) The former cases likewise showed twin muscles lying on the palmar aspect of each interspace, except that between the first and second metacarpal bone, each inserted into the outside and inside of each finger, respectively : 1n these cases the dorsal interossel were normal. There are several anomalies of these muscles on record, but none of them in anywise resemble the foregoing, which I would venture to suggest might throw light on some points of the homologies of these muscles. It has often been a matter of comment that there is a strange want of symmetry in the arrangement of these muscles in the hand, as well as a want of conformity in the attachments of the homotypical muscles in the hand and foot. This is accounted for by Mr. Wood, because, as the middle finger in the hand is the most bulky, it is assumed as the centre of motion; and it has two dorsal interossei to produce its divari- cations, and its divaricator to the pollex excludes from the third meta- carpal bone the divaricator from the pollex of the second digit, and ob- tains an origin for itself from the dorsal aspect of the second metacarpal ; so, instead of being a palmar, it becomes a dorsal interosseous muscle; and this is supported by the fact that the transverse convexity of the dorsum of the hand gives to the metacarpal bone of the middle digit a prominence 449 over the others. Though the explanation may be quite satisfactory, yet it has struck me that perhaps another interpretation might be given in the light of the present varieties. It might be that for each finger as a separate individual member four muscles might be provided in a typical hand, two dorsal interossei, and two palmar, the former as extensors and lateralizers, the latter as flexors and lateralizers; but the fingers being grouped as in the human hand, and the extensor and flexor action being for the most part monopolized by the long special muscles for the purpose, the secondary or lateralizing function becomes paramount; and, as two muscles for each action would usually be unnecessary, a suppression takes place of the superfluous dorsal and the palmar interossei. Then perhaps the dorsal prominence of the third metacarpal is the cause that the muscles which in the human hand become obsolete on the dorsum are the adductors, but on the palmar aspect the opposite set disappear. We still retain a trace of the double nature of the dorsal interossei in their bicipital origins, as I think the deduction arrived at by Meckel may be with reason accepted, that the bicipital attachment of a muscle is usually a sign of the lateral coalescence of separate parts. If this explanation be true, these varieties would show the typical or unaltered state of development, respectively, of each set of muscles. 12. Gluteus quartus of Mayer and Haughton, (ilio-capsular of Harrison). This muscle is not by any means a rare constituent of the human body ; its existence I have noticed 1n many animals; and Professor Haughton has furnished me with numerous instances in which he has found it to be adistinctly existing element, asin the lon, kangaroo, rhea, &c. In man it usually runs from the anterior inferior spine of the ilium, and is inserted into the capsular igament of the hip joint, and sometimes into the anterior intertrochanteric line above the lesser trochanter. It may be of use as a special tensor of the capsule, or as a rotator outwards or abductor of the hip joint, and seems to correspond with the infraspinatus secundus in the shoulder; it varies in degree of development, and is present as frequently as the psoas parvus. / 13. The peronzus quartus I have seen as a distinct muscle, arising from about two inches of the front of the fibula, at the junction of the upper three-fifths: with the lower two-fifths of the bone, above the peroneeus tertius, from which, as well as from the extensor digitorum longus, 1n one case it was completely distinct, and in other instances it was with facility separated. Passing under the annular ligament along with the extensor digitorum longus, it was inserted tendinous into the base of the fourth metatarsal bone. In one subject in which this muscle existed, the peroneeus tertius was absent; in another instance the two tendons arose from the same muscle; and I have seen this tendon de- tached from the outer slip of the long extensor of the toes. In one strong muscular subject the tendon of the peronceus quartus was as strong as the flexor carpi radialis tendon at the wrist. A slip somewhat homotypical I found in the right forearm ofa dingo, running from the dorsum of the ulna to the fourth metacarpal bone. 14. The slip called peronzus quinque, or the band extended to the 4.50 extensor aponeurosis of the little toe, I have seen on several occasions, but I never have found it existing as the tendon of a separate muscle; it always was an offshoot, commonly from the peroneus tertius, or in | three cases from the peronzeus brevis, and as such I have found it pre- sent in Cercopithecus. (Since the writing of this paper I have seen it as a perfectly distinct muscle, arising under cover of peroneus brevis. te I can fully confirm Mr. Wood’s statement as to the frequency of the existence of the abductor ossis metatars1 minimi digiti of Hux- ley, Flower, and Wood. The latter author was the first to direct atten- tion to it as a human muscle; but even before the publication of his paper, I have been long in the habit of demonstrating its existence as a slip, separate from the abductor minimi digiti; indeed I have found it present in nine out of every twelve subjects. 16. A description of a sixth peronzeal muscle has been communi- cated to me by Mr. Macmullen, who found a distinct fleshy belly, taking origin from the lower third of the outer surface of the fibula, over the peroneus longus, and winding round the back of the outer malleolus, to be inserted into the posterior and external surface of the cuboid bone. In this subject the peroneeus tertius was absent, but the longus and brevis were present and normal. 17. Tibio-fascialis anticus was a muscle found in one subject arising from the lower third of the anterior edge of the tibia, over the tibialis anticus, and passing downwards to be inserted into the annular liga- ment, over the extensor digitorum communis tendon, as well as into the lower border of the deep tibial fascia. 18. The levator claviculsee of Wood I have only once seen, in the neck of a spare female subject, and under cover of the clavicular fibres of the trapezius, inserted into the posterior border of the outer third of the clavicle. 19. The levator glandule thyroidei of Sommering I have found either as a separate muscle, or as an offshoot from the inner edge of the sterno-thyroid or the thyro-hyoid muscles. 20. Fibres of a hyo-epiglotticus muscle I have once traced dis- tinctly, under cover of the glosso-epiglottic ligament, from the poste- rior surface of the body of the hyoid bone to the anterior surface of the epiglottis, overlying the so-called epiglottic gland. 21. Crico-thyroideus posticus (somewhat similar to the kerato- cricoid of Merkel) was a small band of muscle, which arose from the side of the cricoid cartilage, directly below, and extending a little ante- rior to the articulation between the inferior cornu of the thyroid car- tilage and the side of the cricoid. From this origin its fibres ran upwards and forwards, to be inserted into the lower border of the thyroid cartilage (Plate VI., fig. 3, a). It was situated below and behind the normal erico-thyroid muscle, from which it was quite separate, and differed in the direction of its fibres. Its cricoid attachment was external to the outer border of the crico-arytenoideus posticus, with which some of its fibres were slightly connected. The larynx in which this muscle la 451 occurred was peculiar, as in it the thyroid cartilage had no superior cornua. 22. A small muscular mento-hyoidean band (Plate V., fig. 2, a), existed single in one subject, but double in another, arising from the inferior surface of the mental ridge on the lower jaw, and running backwards to be inserted into the middle of the body of the os hyoides. For the sketch of this muscle [am indebted to Mr. Macmullen. In all instances it was perfectly separate from the digastric. 23. I have several times found present on the side of the thorax a small or well-developed supra-costalis muscle. Once this occurred in an old though tolerably muscular female. Another instance was in a male subject of enormous proportions; it arose from the lower border of the third or fourth rib, about six inches and a-half from the outer edge of the sternum. On the right side I have generally found it nar- rower and thicker than on the left; it measuredin one instance three inches and three-fourths long, three-quarters of an inch in breadth, and one- eighth of an inch in thickness; but I have seen it much larger. Fromits place of origin it extended vertically upwards, lying on the upper digita- tions of the serratus magnus, and shortly in front of the respiratory nerve of Bell; then, ascending behind the axillary vein and subclavius muscle, it was inserted into the first rib on the right side, in one instance over the origin of the first slip of the serratus magnus. On the left side in this subject, however, and in several cases on the right, it cleared the bone, and, expanding, was inserted into the deep cervical fascia in the poste- rior inferior triangle of theneck. It lay considerably external to the origin of the lesser pectoral, which covered it, with the intervention of a strong aponeurotic expansion, derived from the deep axillary fascia, and its insertion was placed internal to the scalenus anticus. Mr. Wood has described a somewhat corresponding muscle, which, however, differs from the foregoing in being placed anterior and internal to the serratus magnus; and, secondly, in having no upper fascial connexion, but being purely costal in its attachments. His slip extended to the fourth rib, and he has described its course as from above downwards; but as in the most of the instances which I have seen, it evidently acted on the cervical fascia, I have taken the liberty of inverting the order of description. The muscle occurs in several monkeys, in the seal, and in Balenoptera rostrata. It seems to have no connexion with or rela- tional analogy to the rectus sternalis. 24, I have met with a distinct extensor ossis metatarsi hallucis, and have also seen this muscle existing as an offshoot from the anterior edge of the tibialis anticus; in the latter subject there existed (25) an ex- tensor primi internodii hallucis, which lay between the former muscle and the extensor hallucis proprius; this latter slp was perfectly uncon- nected with all the surrounding muscles. In an egret monkey I have seen the extensor ossis metatarsi hallucis without any trace of another extensor for the hallux, while in others of the Quadrumana both the extensor ossis metatarsi and the extensor secundi internodii exist. 452 II. The second class of muscular varieties comprises those instances in which we find normal muscles multiplied by simple reduplication, the double portions either being placed in different planes, or in diffe- rent vertical positions. The former arrangement I have found to be rather the more frequent, and it has occurred, in my experience, to several muscles. We must, however, be careful to distinguish abnor- malities of this class from those of the fifth group, with which they are liable to be confounded; the main distinction being that, whereas in every example of this class all or some of the portions of the varying mus- cles are doubled, in the fifth subdivision, on the other hand, each part is but single, although severed from those others with which it normally should be united. 1. The rhomboideus major I found to be the seat of a partial variety of this class, on the left side of a female subject. It was almost com- pletely split into two planes of fibres, especially along its lower border. At the upper edge of the muscle the fibres of the different planes coalesced more or less distinctly. 2. The pectoralis major has been on sever al occasions partially cleft into two planes, more or less distinctly, and in one case was perfectly severed. This arrangement occurs in the horse, sheep, and dog. 3. The sterno-thyroid was double on the left side of a strong male subject, the two portions lying parallel; and (4) on the same side of this subject there was a double levator anguli scapule. 5. In the right forearm of a thin female subject the supinator longus was double for the largest part of its extent, while the same variety was presented in a corresponding extremity in the case of the (5) palmaris longus. The double arrangement of the former muscle occurs, according to Meckel, in the three-toed sloth, and in the anteater; it is likewise cleft in the seal. 7. The abductor pollicis brevis manus I found presenting this ano- maly—the two muscles lying parallel, and separated by a cellular interval. This state was described by Sommering, who believes it to be the normal arrangement of the muscle. 8. The rectus capitis lateralis, and (9) rectus capitis posticus major and minor, were each in at least one instance found double. 10. The extensor ossis metacarpi pollicis I have seen in several in- stances presenting this irregularity: in one case three parallel muscles and tendons existed ; in another the muscle at first was single, but ended below in two bellies, which were inserted by tendons quite separate and distinct from each other, the inner of which overlapped the outer (11). The same varieties I have seen to occur in the case of the extensor secundi internodii pollicis. 12. The extensor minimi digiti I have likewise seen entirely doubled. Usually, however, when this condition occurs, the tendons and bellies of the two muscles separated except for about an inch or so from the origin, and by no means unfrequently a single belly existed, from which two tendons were detached, both of which were distributed to the little 453 finger. I have likewise seen three tendons arising from a common muscle, one of which passed to the fourth finger, and was continuous with the extensor tendon of that digit opposite the end of the first pha- lanx; the other pair of tendons were, as usual, distributed to the little finger. This arrangement I have likewise found in a species of Cebus. 13. The soleeus was in one subject doubled ; the accessory or second portion lying under cover of the normal muscle, and connected to the deep-seated surface of the tendo Achillis. 14. Two perfectly distinct planes of fibres I have been able to detect in the gluteus maximus on several occasions, especially along the infe- rior border of the muscle: these were separated by a cellular lamina. III. Under the third head I place all those irregularities which arise from the presence of additional origins, supernumerary tendons, unusual insertions orrelational deviations from the ordinary arrangement of parts; and these, as might be supposed, constitute the most numerous group of muscular anomalies. They may be the results of original abnormal development, or the products of disease or injury. The latter forms I have, however, excluded as far as possible from my list, as they can- not possess much value in comparative anatomy. I have found illus- trations of this class involving the following muscles :— 1. Latissimus dorsi. In many cases I have found this muscle to be errant either in its origins or insertion. The former have been ex- tended as far upward as the fourth dorsal spine, or have not reached beyond the first lumbar vertebra, or have been attached to the inferior angle of the scapula; and the latter I have seen sometimes sending a considerable accessory slip from its lower border into the fascia of the arm. This band attains a considerable degree of development in Cebus, and other monkeys. A portion of this tendon is often continued into the long head of the triceps, and this I have found to occur about three times in every thirty subjects. I have also seen the long tendon of the triceps taking an origin more or less extensively either from the lower border of the latissimus tendon alone, as in Cebus, or from it and teres major combined. 'Very much more rarely a fascial expansion, or even a musculo- tendinous slip, has passed from the lower border of the latissimus dorsi down as far as the olecranon process; this we find to exist in the gibbon, in Ateles, Cynocephalus, and many others of the Quadrumana. A similar portion exists in the horse; and a muscle somewhat corre- sponding I have traced in the pig, running from the inferior angle of the scapula to the fascia on the inner side of the limb, over the triceps. In many of the instances among the Quadrumana, where this muscle exists as a supplement to the triceps, 1t is quite separate from that muscle, even to its insertion ; and it is not improbable that it may be the fore-limb homotype of the sartorius muscle, asin both cases the muscles are superficial to the rest of the extensor mass, in bothinstances placed on the extensor aspect of the limb, and both usually run from without in- R. I. A. PROC.—VOL. IX. 3 0 454 wards. In confirmation of this there are instances recorded both in man and. other animals where the sartorius femoris ended either by being inserted into the extensor muscles, the fascia of the thigh, or the patella. Another slip of the latissimus I have found crossing the bicipital groove, and binding the long head of the biceps in its place, to be inserted into the anterior edge of the groove, under cover of the tendon of the pectoralis major: the same arrangement I have found in Cer- copithecus. A slip of fibrous tissue also exists not unfrequently, pass- ing from the upper border of the tendon of the latissimus to the lower and inner border of the capsular ligament of the shoulder joint, stretching along the inner lip of the bicipital groove, and corresponding to the suspensory frenum of Winslow from the great pectoral tendon along the outer lip. 2. The lower costal fibres of the great pectoral muscle, in a stout female subject, detached a distinct chondro-epitrochlear slip, which, arising from the seventh costal cartilage, passed outward, and ultimately downwards, to be inserted into the upper part of the inner condyle of the humerus by around tendon. ‘This variety is of interest, as usually the costal fibres of this muscle are inserted above and behind the sternal and clavicular portions. ‘This muscular slip has been found taking different courses, and inserted either into the brachial aponeurosis, or intermuscular septum, when it is called the chondro-fascial, or even into the short head of the biceps, the latter attachment being similar to the mode of arrangement in Hylobates leuciscus, in which the entire short head of the biceps springs from the pectoral muscle: the former we find in the pig, where the lowest fibres of the pectoral extend down to the fascia over the inner side of the ulna. I have found this epitro- chlear slip in one instance detached from the clavicular portion of the muscle. I have also found the long head of the biceps splitting the tendon of the great pectoral, and passing down between the costal and sternal fibres which were behind it and the clavicular fibres which lay in front of it—a condition which has its prototype in Quadrumana. 3. The omo-hyoid sometimes took an origin from the posterior border of the middle third of the clavicle. In one of these cases its scapular origin was completely suppressed, and its clavicular attach- ment was overlapped by the extended fibres of the trapezius. 4. The upper fibres of the serratus magnus of a slender male subject extended at their insertion as far forward as the posterior border of the suprascapular notch, behind the omo-hyoid muscle, and so occupied the entire of the superior costa of the scapula. In this subject, likewise, the superior and middle parts of that muscle were separated by a con- siderable cellular interval, so as to appear quite distinct from each other. This variety occurred to Theile in a subject in which the omo- hyoids were absent. 5. The rectus abdominis I have found to vary much in the extent of its attachments: sometimes it ascended as far as the fourth 455 rib, lying superficial and internal to the great pectoral; on other occa- sions it passed outwards as far as the cartilage of the eighth rib. The former case seemed to be an attempt at a rectus sternalis. 6. The sartorius muscle I have seen extending at its origin along Poupart’s ligament for a short distance from the anterior superior spine of the ilium, and by its deep-seated surface united to some of the su- perficial fibres of the iliacus internus. 7. My friend and former pupil, Dr. Raye, has furnished me with a note of an interesting variety, which he had found occurring in the case of the subclavius muscle. It is well known that not very un- commonly this muscle is continued outwards beyond the clavicle to the acromion process of the scapula; but in this instance, ‘‘on the left side the muscle was not inserted into the clavicle at all, but, passing free from that bone, was attached to the ligament of the notch, and to a small portion of the outer extremity of the superior costa of the scapula external toit. The omo-hyoid arose more internally from the superior costa, its usual position being occupied by the subclavius. The supra- scapular artery separated these muscles. The subject was a female, and the same anomaly occured on theright side.” Mr. Wood, in de- scribing a similar irregularity, mentions that it coexisted with a normal subclavius; and consequently he regards it as a distinct muscle. In his subject, ikewise, it was united at its insertion to the omo-hyoid; so in both these respects the instance recorded by him differs from the case given above. Mr. Wood regards it, and with sufficient reason, to be the representative of the Mammalian sterno-scapular muscle, which I have found in many Mammals taking a similar course. Ina porcupine which I lately dissected this muscle closely resembled our anomaly, except that, crossing over close te the superior costa, it was inserted into the posterior two-thirds of the spine of the scapula. A similar arrangement I have found in a pig. 8. The occurrence of additional heads to the biceps flexor cubiti has long been familiar to anatomists, and is among the best known of muscular anomalies, having been described by Struthers, Meckel, Theile, Kelch, and others. I have not in my dissections verified Theile’s experience that this variation occurs once in every eight or nine subjects, as out of forty subjects taken at random through the last session I noticed its presence only in two; and from my previous ex- perience of its occurrence I would be inclined to state its frequency as being about once in twenty-five cases. Among the different forms of this variety, the following are the principal :—(1). The most common consists of a slip from the bra- chialis anticus, interesting as the representative of the short head of the biceps flexor cruris; (2), sometimes a similar head may come from the supinator longus; (3), from the pronator teres; or, more, rarely (4), I have seen a band arising from the humerus, inseparable from the insertion of the coraco- brachial, and uniting with the biceps at the middle third of the arm; (5) the accessory origin may be, as described by Meckel, from the ereater tuberosity of the humerus ; (6), or, as de- 456 scribed by Mr. Wood, from the lesser tubercle: of the former I have notes of two cases, of the latter three instances have occurred in my experience. In all cases but one which I have met with those anomalies . have been symmetrical. (7). An accessory head may pass from the great pectoral to the short head, as in Hylobates; or (8), a similar slip may run from the lesser pectoral to the same place: these latter probably are about the rarest forms of supplemental origin. 9. A radial origin for the flexor carpi radialis in place of, or in conjunction with, the ordinary condyloid head, is another variety which I have noticed. The aberrant slp in these cases sprang from the bone, between the insertion of the pronator radii teres and the radial origin of the flexor sublimis digitorum. In one instance, how- ever, 1n which the pronator teres was destitute of a coronoid head, a distinct tendinous slip passed downwards and forwards from the inner lip of the coronoid process of the ulna, and was inserted into the outer and deep surface of the radial flexor, being separated from the con- dyloid origin of the muscle by the median nerve and the brachial artery. 10. The palmaris longus is frequently the seat of variation. I have found it reversed; its tendon being connected to the mner condyle, and its lower end being fleshy for about two inches and a half, and in- serted below into the annular ligament and palmar fascia; but this variety may rather be regarded as arising from the presence of a new muscle; the palmaris longus secundus taking the place of the obsolete palmaris longus, as I have seen several times the two muscles present in the one forearm—first the proper palmaris, and to its inner or ulnar side the accessory muscle, as above described (Plate VIIL, fig. 1, a,b). Ihave found an intermediate variety of this muscle, in which the origin and insertion were tendinous, while the fleshy belly, two inches long, had a central position (Plate VIII., fig. 2, c). ‘These va- rieties have, for the most part, been already recorded by Quain and Cloquet. The site of origin of this muscle, likewise, may vary: I have found it springing from the lowest point of the condyle, under cover of the flexor sublimis digitorum, or from the radius, in place of the radial origin of that muscle. Its insertion I have seen connected by oblique -tendinous bands to the pisiform bone, external to the tendon of the flexor carpi ulnaris. In other subjects I have seen a slip of the flexor sublimis taking its place; and sometimes, but very seldom, its tendon was united below to that of the flexor carpi ulnaris, reminding us of its position in the two-toed anteater, where, according to Meckel, these two form but the one muscle. This latter condition I have seen in two subjects. 11. The flexor pollicis longus possesses frequently a condyloid and occasionally a coronoid origin, which is sometimes large enough to pro- duce by its tendinous intersection, where it unites with the radial fibres, the appearance of a large digastric muscle, and this band in one subject was a little complex in its relations. It sprung from the process in the situation where usually the second head of the pronator teres 457 arises (which, however, was in this instance deficient), and shortly after it was joined by a slip from the flexor digitorum sublimis. The con- joined slip thus formed passed behind the ulnar artery, and terminated in the flexor pollicis longus. 12. The extensores carpi radialis longior and brevior are not un- frequently the subjects of altered attachments and course : most usually, however, their varieties belong to the class of anomalies by coalescence. Ihave in my notebook the records of a very singular interchange which occurred between the tendons of these muscles. In this subject the tendon of the extensor longior, a short distance below its origin, divided into two slips, one of which, becoming tendinous, passed off to unite with a similar offshoot from the extensor brevior. The conjoined tendon thus formed passed for a short course between the slips which represented the typical muscles, and then bifurcated, each of the result- ing tendons being inserted under cover of the normal insertions of the type muscles, respectively, into the second and third metacarpal bones. This may be in some slight degree a representative of the mode of in- sertion in the ornithorhynchus, where a single tendon terminates in three slips for the three outer metacarpals; but the peculiar double mode of insertion is, to my knowledge, unexampled in the animal king- dom. In another subject the extensor carpi radialis brevior was inserted into the third metacarpal bone by three tendons. 12. The triple insertion of the extensor ossis metacarpi pollicis I have repeatedly noticed, but on several occasions, they have been ar- ranged in a manner different from that usually described. Sometimes two of the fasciculi passed outwards to the first phalanx, while the other band was connected to the trapezium, or to the metacarpal bone, or to the short abductor pollicis. Again, I found the slips sent, one to the abductor, a second to the opponens, which also was connected by a short recurrent band to the trapezium, while the third was attached as usual to the metacarpal bone. 13. The extensor secundi internodii pollicis I have commonly (about once in every nine subjects) found with a double tendon—the supplementary portion being inserted into the base of the first phalanx, and lying internal to the normal tendon. 14. The abductor minimis digiti I have found on two occasions pre- senting an anomaly similar to number 14 in Mr. Wood’s paper (‘Pro- ceedings of the Royal Society,’ June, 1864), only that in my subjects the deviating muscle was not the flexor brevis, but the abductor, which arose by two heads—one a superficial and external, from the tendon of the palmaris longus and fascia of the forearm, about an inch in one sub- ject, and three inches in another, above the anterior annular ligament, This portion crossed the ulnar artery and nerve, covering the flexor brevis, from which it was quite distinct. The deeper or normal head of this muscle united with the superficial in one case by fleshy fibres at the wrist, but in the other by a tendon near the fingers, both being inserted in common into the inner side of the first phalanx of the little finger. 458 Though I have never seen a similar arrangement of this muscle in any animal, yet a somewhat corresponding slip has been described, and I have seen the same appearance in connexion with the abductor pollicis in the Cynocephalus porcarvus and other Quadrumana. It has been sug- gested that these varieties might be modifications of the palmaris secun- dus or accessorius before alluded to. 15. The palmar lumbricales I have found to vary very frequently in their origin, principally by the occurrence of additional heads from the inner sides of the neighbouring tendons. This variety occurrred to the second lumbricalis in one instance, and to the second and third in another. The third is by far the most frequent subject of variety, as I have seen two irregularities of that muscle for every single instance of variation in the others. 16. An aggravated case of talipes varus, occurring in the foot of a female subject, exhibited some rare and interesting varieties in the posi- tions, attachments, and relations of some of the tendons about the ankle. The peronzeus longus on the right side, after winding around the outer malleolus, grooved the external side of the os calcis, being bound down by a strong double external annular ligament. It then passed forwards, inwards, and a httle upwards, soon splitting into three tendons, which were inserted into the tarsal extremities of the metatarsal bones of the fifth, third, and first toes. There was no sesamoid tubercle or cartilage where 1t wound round the caleis, but a very strong expansion of the calcaneo-cuboid ligament held it in its place. On the left side, although the foot was distorted, the muscle had only its normal insertion. The chief feature of interest in the variety arises from the fact that in the upper extremity the flexor carpi ulnaris, which is the undoubted homo- type of this muscle, assumes a somewhat similar mode of arrangement in some animals, as in the striped hyena, where, from the pisiform attachment of this tendon (the homotype of the sesamoid bone, so fre- quently existing in the tendon of the peroneeus longus), four slips are. continued to the four outer metacarpal bones. I have seen the same arrangement ina seal. In the Ursus arctos a ligamentous slip of a s1- ‘milar nature seems hkewise to continue the insertion of the muscle from the pisiform to the fifth metacarpal bone. In the porcupine and some other rodents, the peroneeus longus sends slips to the first, second, and third metatarsal bones, as well as to the cuneiforms. 17. In the same subject the tibialis anticus, after gliding over the anterior surface of the tibia, and passing under the anterior annular ligament split mto two portions—one of which, a round internal slip, was inserted into the inner side of the scaphoid and ento-cuneiform bones; while the other, broad and aponeurotic, passed externally, to be attached to the outer side of the astragalus and os ealcis. Beneath this expan- sion, and winding round the former round tendinous slip as a pulley, the tendons of the extensor digitorum longus and extensor hallucis pro- prius ran, turning backwards, inwards, and upwards, so as to form an angle of sixty degrees. 18. The peronzeus tertius; in a stout female subject, sent a strong 459 slip inwards, which united with the short extensor tendon of the little toe. In the leg of a thin subject, also a female, a second peroneal slip arose from the outer side of the long extensor tendon of the little toe, and was inserted in front of the nor rmal peroneeus tertius into the fift h metatarsal bone, and likewise by a thin but strong expansion into the base of the fourth metatarsal bone (peroneus quartus). 19. The plantaris tendon in one instance terminated about the middle third of the back of the leg by expanding into a flat aponeurotic lamina, separating the soleus from the gastrocnemius, and terminating by being continuous with the deep tibial fascia at the inner border of the former muscle; the outer edge united with the conjoined tendons of the muscles of the calf. The facility with which the plantaris tendon can be unrayelled and expanded is very striking, but I have never seen a natural expansion of it except in this case: in another in- stance this tendon, for the lower two-thirds of the leg, was inclosed in a canal in the soleus tendon, from which, however, it was quite sepa- rate. 20. From the back of the lower extremity of the femur, about a quarter of an inch external to the line leading from the inner condyle to the linea aspera, there arose a round fleshy mass, more than an inch above the inner head of gastrocnemius, which descended, crossing over the popliteal nerve, to be inserted by a short tendon into the outer head of the gastrocnemius muscle, near the point of its convergence with the inner head (Plate I[X., fig.1, f). If we are to recognise in the gastrocnemial series of muscles the representatives of the conver- gence of the pronator and supinator muscles of the upper limb, this band might be the representative of the upper origin of the long supi- nator. 21. A composite special muscle to flex the little toe in the foot ofa slight female was made up of the following elements :—1st, a muscular band from the posterior part of the os calcis, below the sustentaculum, and above and internal to the musculus accessorius; secondly, a slip from the cuboid and sheath of the peronzus longus; and, thirdly, a small thread from the long common flexor. These three parts united to form a single tendon, which ran to be inserted without splitting into the last phalanx of the little toe. A séparate flexor brevis existed for this toe in the third layer of muscles. 22. In another female subject the outer slip of the musculus acces- sorius detached a long flexor tendon for the little toe, which split the fourth tendon of the flexor brevis, the latter being of extreme minute- ness. Nearly the same arrangement was seen in another female, where the outer part of the accessorius formed two tendons, one of which united to the flexor digitorum longus, while the other passed to the little toe direct, ee receiving a slender thread from the last-named muscle. I may here record the occurrence of pao bones which I have found in the heads of the gastrocnemius, in the peronwus longus (not 460 unfrequently), in the tibialis anticus rarely, and in the tibialis pos- ticus. The biceps flexor cruris in the lower limbs of a male subject arose not only by their long heads from the tuber ischii, but these were con- tinued upwards and backwards over the great sciatic ligament to the side and lower border of the sacrum. | TV. Abnormalities of coalescence may occur in two ways—either by the fusion, more or less complete, of the opposed margins of neighbouring muscles, or by the presence of connecting bands, uniting muscles which typically are distinct. The latter mode of connexion is the more fre- quently met with; but the two varieties often merge into each other. The former I have seen in the following muscles :— 1. The anterior belly of digastric and its fellow of the opposite side I have seen to unite, so as to form one mass of interlaced muscular fibres, either closely united to the mylo-hyoid, or in other instances separated from it. This arrangement is the normal state in Jnuus sylvanus, and in a few other species of Quadrumana. A partial form of this variety I have also seen, in which the left anterior belly sent a very large fasciculus below the chin to the median line, there to be inserted into the fascia. 2. I have in one instance found the anterior belly of digastric, on the right side, inseparably connected to the mylo-hyoid ofits own side, with which its fibres interlaced. 3. The two genio-hyoid muscles several times were absolutely inseparable, there being no trace of the usual cellular raphe between them. The same mode of fusion is the usual arrangement in the motor uvule. 4, The trapezius and deltoid have been in my experience several times united by tendinous and fleshy fibres, crossing the spine of the scapula. The complete union of these muscles is very common in the non-claviculate Mammals, especially at their internal extremity. 5. The infraspinatus and deltoid were in one case fused together, as occurs partially in the pig and camel. The union was produced by the lower fibres of the former muscle becoming continuous with the posterior fibres of the latter. 6. The outer border of the clavicular fibres of the great pectoral and the inner edge of the deltoid I have seen partially fused together, especially at their lowest part. The same arrangement I found in Cynocephalus. I have never met with a complete fusion of the above muscles in man, but a case of the kind is described by Koster (‘‘ Neder- landsch Archief,” 1864). | 7. The deltoid and supinator longus muscles were perfectly blended in the left arm of a strong, well-developed subject, so that a band three quarters of an inch broad, and half an inch thick, was con- tinued from the acromion process to the tendon, which was inserted into the rough surface above the styloid process of the radius. 461 8. The complete fusion of gluteus medius and minimus was one of the rarest anomalies which I have met with. The anterior fibres of these muscles, however, are not unfrequently united together inseparably. 9. The gluteus medius and pyriformis I have not uncommonly found united at their insertion; more rarely I have found their fleshy portions connected; and in one subject the opening for the gluteal artery was the only appearance of the interval which normally separates these muscles. This mode of coalescence I have seen in a species of Cebus, C. apella. 10. The palmaris longus I have once found coalescing with the flexor digitorum sublimis, as before mentioned. This is the natural arrangement in Cebus. 11. Another variety of coalescence has been previously described as existing between the palmaris longus and the flexor carpi ulnaris. 12. The outer edge of the brachialis anticus was occasionally inse- parable from the inner border of the supinator longus; in these cases the musculo-spiral nerve passed in a deep tunnel below the connecting fibres. 13. The deep head of the flexor pollicis brevis manus not unfre- quently was inseparable from the adductor pollicis, except at the spot where the deep palmar branch of the radial artery passed between them. The union of muscles by connecting muscular or tendinous slips - is of frequent occurrence, and I have seen it taking place with the following :— | 1. The lower border of the great pectoral, and the upper edge of the external oblique, which have been very often so distinctly con- nected that fibres and fasciculi may be easily traced from the tendon at the bicipital groove to the linea alba at the umbilicus. 2. The coraco-brachialis and brachialis anticus I have found united by some fibres; and this anomaly Meckel has thought of very great importance, as establishing the homotypical place of these muscles, as shall be noticed hereafter. 3. The extensor ossis metacarpi pollicis and primi internodii pol- licis were not unfrequently connected by the interchange of muscular or tendinous fibres, and in one case coalesced for their whole extent, ex- cept from the groove in the radius to the separate insertions of the two divisions of the tendon. The same occurs in Jnuus sylvanus and Cyno- cephalus porcarvus. 4, The flexor sublimis and profundus often interchange muscular bundles; and, 5. The flexor profundus and flexor pollicis frequently are united by a similar interchange of slips. In one case the flexor tendon for the index finger mainly arose from the flexor pollicis; or, conversely, fibres often run from the flexor profundus to the flexor pollicis.. R. I, A. PROC.—VOL. IX. 3P 462 These are attempts at the complete union of the two muscles which oc cur in the majority of Quadrumana, 6. The biceps in several instances was extended at its insertion by « tendinous band, internal to the radial insertion, to form one of the origins of the flexor carpi radialis: in this instance the pronator teres was small, and was at its origin completely under cover of the flexor carpi radialis and palmaris longus. The brachialis anticus tendon is frequently connected with the coronoid head of the pronator teres, of which sometimes it forms the entire. 7. The extensores carpi radialis longior and brevior were thus connected frequently, in degrees varying from complete fusion to junc- tion by slender tendinous slips. The former ule occurs in the horse, camel, and sheep. 8. The connecting band between the far ae dorsi and the pectoralis major was found very often; its attachments varied, being connected with the lower costal fibres ‘of the latter in one instance, whereas in most of the other cases it joined the upper sternal or costal fibres. This connexion is very common; it occurs in most of the Felida, in the mole, and many other animals. 9. The brachialis anticus in one case sent off a slip to form one of the origins of pronator teres distinct from that already noticed; and in another subject dissected by me, during the past session, the latter muscle possessed a remarkable series of origins, consisting of :—1st, a tendinous band, sent off from the biceps between its ordinary tendon and the commencement of its semilunar fascia; 2nd, a thin tendinous slip from the inner condyle, four-fifths of an inch long, and one-fifth of an inch broad; and, 8rdly, by a thick fleshy head from the internal intermus- cular septum and internal condyloid ridge of the humerus, for the extent of two inches, ceasing an inch and a half above the point of the condyle. This very complex arrangement is, I think, undescribed. (Plate VIIL., MO Bt (O00) 10. The peronzi were occasionally united by tendinous and fleshy slips, but this arrangement is not of frequent occurrence. 11. The modes of connexion existing between the tendons of the flexor digitorum longus and flexor hallucis longus are of very great. in- terest ; and, as they have given rise toseveral discussions, I have care- fully sought and examined their nature. Ihave found some connexion present between these tendons in at least eight out of every ten sub- jects. The union varied in strength and nature : sometimes it was merely the interchange of a few tendinous fibres, or a large cord from one tendon to the other; most commonly these ran from the flexor hallucis to the flexor communis, especially to the tendon of the second toe; but in two or three instances I have seen them running in the reverse direction. In some cases a perfect fusion took place between the tendons; and much more rarely the flexor hallucis sent off a cord larger than its own proper tendon, which subdivided into four tendons, which united with the tendons of the flexor communis, opposite the metacarpi phalangeal articulations, forming with the latter tendons 463 very acute angles. In one of these subjects the lumbricales were arranged In two sets: one group corresponded to the accessory or deeper tendons, and these were connected with the third and fifth toes; another series was placed in connexion with the ordinary flexor tendons, and were inserted into the second and fourth toes. This peculiar mode of arrange- ment has not been before described. A minute and careful description of these modes of union, by Mr. Turner, will be found in the “ Trans- actions of the Royal Society of Edinburgh,” vol. xxiv. (December 19, 1864). 12. In the upper third of the arm of a female subject a small round muscular bundle crossed over the brachial artery: it arose from the lower border of the tendons of the latissimus dorsi and teres major muscles (which were inseparably united), and ended below in the tendon of the coraco-brachialis muscle. Its length was about two inches, and it lay underneath the brachial aponeurosis. This slip resembles some of those recorded by Dr. Struthers in the ‘“ British and Foreign Medico-Chirurgical Review ’’ for 1854; but was peculiar in that it com- menced by tendinous fibres, which crossed the tendon of the latissimus dorsi at right angles, and that its fibres ran, not transversely, but ob- liquely downwards and outwards over the artery. Y. Varieties by segmentation, or the fission of normal muscles into separate parts, are of frequent occurrence, and may indicate that the muscle so divided is composed of several homologically distinct seg- ments, which have coalesced, or else the splitting may be accidental, and may arise from the atrophy or non-development of the natural connect- ing fibres which ought to connect the severed portions. 1. The pectoralis major was very commonly—indeed, in the majority of eases—thus divided, the sternal and clavicular fibres being separated by a deep and wide interval. The costal fibres were rarely as distinctly isolated from the sternal portion as were the latter from the clavicular; and this condition I have seen in a pig, also in several monkeys. 2. The upper portion of the serratus magnus I have hkewise seen perfectly distinct from the middle and lower parts of the muscle—a con- dition which I have found in Cercopithecus and Cebus, where the upper portion of the muscle is inseparably connected with the levator anguli scapule. 3. The sterno-cleido-mastoid sometimes was similarly divided, the spinal accessory nerve passing through the interspace between the two nearly parallel bellies. These Meckel considers as the representatives of two muscles—a sterno-mastoid and a cleido-mastoid—which he describes as the cervical equivalents of the rectus and pyramidalis muscles in the abdomen, and the antitheses of the splenii capitis and colli. 4, The biceps fiexor cubiti in a similar manner I have been, on two or three occasions, able to separate throughout the whole extent of its fleshy belly as far as its tendon, into two parts—thus showing the com- posite nature of this muscle, and that it is most probably the represen- 464 tative, not of the rectus femoris, but of the hamstrings of the lower extremity; the long head representing, doubtless, the origin of the semi- membranosus, which is typically placed nearer to the articulation than either of its congeners, and which also is the more external and most tendinous at its origin. ‘The coracoid, or short head, thus may repre- sent the ordinary long head of the biceps cruris ; and the humeral acces- sory slip in the arm, when present, is the evident homologue of the short head of the last-named muscle. In a few of the Quadrumana I have been able to separate the heads of the biceps in a similar manner. In this representation of the homotypical relations of the flexors of the leg and forearm’ it will be seen that I have differed materially from Meckel’s theoretical comparison of these muscles; as this anatomist, from the occasional occurrence of a connecting band between the coraco- brachialis and the brachialis anticus, has considered that these muscles are parts of a modified representative of the semimembranosus, divided transversely in the midst, and having both its severed ends tacked on to the shaft of the humerus. There are, however, many valid objec- tions to this explanation, as it would make the representative of the semi- membranosus to arise internal to the other flexors, which is usually not the case with that muscle ; also that it is never united with the biceps at its origin ; and, lastly, that it usually arises by a tendon, and not fleshy; besides, as we shall see hereafter, the coraco-brachialis may claim a closer relation to another class of muscles than to the hamstrings. 5. The deltoid muscle is sometimes completely divided into two parts, clavicular and scapular. I never, however, have seen the fission extend- ing in so complete a manner as in the instance described by Meckel, where the clavicular, acromial, and scapular fibres were all perfectly dis- tinct and separate. 6. The coraco-brachialis in a few instances (three or four) was par- tially divisible into two distinct planes; and in one subject these were perfectly differentiated and separated by the external cutaneous nerve. Of the two lamine in this instance the superficial was inserted lower down than usual, and arose from the tip of the coracoid process, uncon- nected with the short head of the biceps; the deeper portion was con- nected intimately with that muscle. I would look upon this variety as of very great interest in determining the homotypical relations of this muscle, which, I think, we are justified in considering as the represen- tative of the adductor mass in the hinder limb; the upper or shorter part may perhaps represent the adductor brevis, or more probably magnus, while the longer and more superficial element is the evident homotype of the adductor longus. This we learn—lIst, from its origin, the dimi- nished homotype of the ischiatic element, and this in a situation where the pubis is obsolete ; 2nd, from its relation to the brachial artery ; and, 3rd, from its insertion. Among the Mammals we find the coraco-bra- chialis thus divided in the ornithorhynchus, lemur, bear, and others. | 7. The supinator longus and (8) psoas magnus were split into two portions in one subject—the former by the radial nerve, the latter by the anterior crural. 465 9. I have likewise found the posterior sacral and coccygeal fibres of the gluteus maximus severed from the rest of the muscle, so forming the representative of the agitator caude of quadrupeds. 10. The anterior fibres of the gluteeus medius were in a few instances severed from the posterior, and formed a strong distinct scansorial muscle, 11. The quadratus femoris was three times split into two parallel portions. I have never seen any further segmentation of this muscle, although Jancke has described a triple division. 12. The trapezius I have found once distinctly divided into two parts: the upper or cranial portion, strong and distinct, arose from the usual situation of the occipital bone, and passed outwards, forwards, and down- wards, to the clavicle, forming a distinct occipito-clavicular muscle; the origin of the lower portion extended: no higher than the ligamentum nuche, corresponding to the spine of the fifth cervical vertebr a, andits insertion fell short of the acromion process. A partial attempt at this mode of division I have seen, and I have likewise found this upper or occipito-clavicular muscle to be deficient; perhaps it may be the repre- sentative of a distinct element, although so frequently united to the rest of the trapezius. 13. The levator anguli scapule [ have seen split into three parts, the slips from the transverse processes of the third, fourth, and fifth cervical vertebree remaining separate as far as the insertion of this muscle. 14, The flexor sublimis digitorum has frequently displayed differen- tiation to a very considerable extent: in the right forearm of one subject, and in the left of another, it was divided from its origin into two parts, of which the outer was distinctly digastric. Its first belly arose from the inner condyle, and about three inches below ended in a tendon, which, after running for about two inches, formed the second belly, which detached from its lower extremity two tendons for the outer pair of fingers. The inner portion of the muscle also arose from the condyle, but no radial origin was present for it or its fellow; it terminated by tendons for the inner or ulnar pair of fingers. In stenops, Meckel de- scribes the whole of this superficial flexor as being digastric; and it is interesting to find an approach to that condition in the present instance. In two other subjects the flexor sublimis was split into four slips up as far as to within an inch of the inner condyle. No radial head was pre- sent in these instances. 15. The subscapularis muscle in the arm of a thin female was split into two portions by the circumflex nerve (Plate VIL., fig. 1, a) :' the superficial or inferior part arose by two tendons from the posterior and inferior border of the scapula, and, passing below but on a plane super- ficial to the remainder of the muscle, was inserted into the capsule of the shoulder and the tip of the lesser tuberosity; this portion did not pierce the capsular ligament. 16. The adductor magnus femoris has been often completely divided into an upper and lower part, the separation occurring sometimes in the situation of the middle perforating branch of the profunda artery. I 466 have found the same arrangement in the dog, dingo, and several other animals. 17. The flexor brevis pollicis manus was also frequently severed into two perfectly distinct muscles. The same state of perfect differentiation I once saw in the extensor brevis digitorum pedis in the right foot of a female subject. 18. The brachialis anticus I have found in one subject split nearly through to its insertion, the cellular interspace between its heads ex- tending down almost to the elbow. A distinct portion of this muscle I found on one occasion arising from the intermuscular ridge of the hu- merus. 19. The pyriformis muscle I have seen in different degrees of fission, sometimes the insertions of the two segments being apart; but more commonly two muscular belles have ended in a common tendon, and a part (usually the peroneal portion) of the great sciatic nerve passed backwards between them. 20. Sometimes the costal fibres of the latissimus dorsi were separated from the iliac portion of that muscle as far as the tendon. 21. The ericothyroid I have once seen split into two parts. VI. Of our last series of varieties we have two subdivisions —the first comprising those cases in which normal muscles are completely obsolete, - and the second including those instances where partial suppression occurs; to these might be added varieties by degeneration ; but it would be perhaps more correct to exclude them entirely from our enumeration, as they can have but little bearing upon questions of comparative myo- logy, as being the results of influences acting upon parts which other- wise would have been perfect in their embryonic and developed condi- tions. Complete suppression I have found in cases of— 1. Platisma myoides; 2. zygomatici, major and minor; 3. levator palpebree superioris, on both sides of a female subject, in whom there was no sign of ptosis; 4. pyramidalis nasi; 5. trachelo-mastoid ; 6. ser- ratus posticus superior, very rarely absent; 7. serratus posticus inferior ; 8. sterno-thyroid ; 9. omo-hyoid, twice—in one instance on both sides, and in the other a rudiment was visible on the left, while the muscle was completely absent on the right; 10. triangularis sterni ; 11. palmaris lon- gus; 12. lumbricales manus, and in one case lumbricales pedis, except the one for the third toe; 138. pyriformis; 14. psoas parvus, so fre- quently absent, that Theile considers it not to be a normal constituent of the human body, although Meckel falls into the singular error of say- ing that it is not often absent; 15. plantaris more freqnently absent than palmaris, in the proportion of three to two; 16. gemellus superior, as mentioned by Gantzer, and as we find in stenops; 17. gemellus in- ferior, as occurs in the kangaroo and ornithorhynchus; 18. peronzus tertius; 19. transversalis perineei; 20. transversus abdomini in one instance; 21. palmaris brevis; 22. scalenus anticus; 23. the stylo- hyoid muscle; 24. transversalis pedis; 25. tensor tarsi. Partial suppression I have found to take place regarding—1. The 467 scapular head of the omo-hyoid ; 2. the occipital portion of the trapezius ; 3. the long head of the biceps; 4. the coronoid head of the pronator teres——- this is absent in many Quadrumana; 5. the radial- origin of the flexor sublimis, likewise deficient in monkeys; 6. the outer slips of the extensor digitorum longus and of the brevis in the foot ; and, 7, the tendon corre- sponding to the former in the hand; 8. the long flexor tendon for the little toe; and, 9, the short flexor for the same digit; 10. the sternal head of the sterno-mastoid. Mr. Avexanver Macarisrer, Demonstrator of Anatomy, Royal Col- lege of Surgeons, Ireland, also read the following paper :— _Noves oF two UNDESCRIBED LIGAMENTS IN THE Human Bopy. Tuer are some ligaments in the human body, which, although compara- tively distinct, seem to be as yet undescribed by anatomists, as I have sought in vain for a notice of them in most of the standard works on prac- tical anatomy. One of these structures is connected with the scapula, the other with the hip joint. The first, which I propose to name coraco-glenoid (Piate IV., fig. 1, c), is a flat fasciculus, of varying strength and distinct- ness, which passes from het posterior and external aspect of the coracoid process, underneath and sometimes attached to the coraco-acromial liga- ment, downwards, backwards, and outwards, obliquely, to be inserted into the glenoid ligament, and into the posterior and superior part of the lip of the glenoid cavity ; extending backwards and downwards into the neck of the scapula, in one subject so far as to be continuous with the glenoid attachment of Sir A. Cooper’s spino-glenoid ligament. To expose this coraco-glenoid band, we require to detach and throw down- wards the deltoid muscle from its origin, to cut across and reflect the eoraco-acromial ligament; and then, if we divide the supraspinatus tendon, and draw the humerus downwards, and outwards, so as to render the capsule and its coraco-humeral accessory band tense, this structure will be exposed to view. It is connected at its origin with the coraco- humeral ligament, with which its fibres passing from the coracoid attach- ment decussate ; but they are perfectly distinguishable by their difference in direction, as they form nearly a right angle with each other. Its outer border gives attachment to some fibres of the capsular higament, which rarely I have seen distinctly split by it; its posterior fibres are often con- tinuous with the periosteum at the root of the coracoid process, or else they may be free along their inner edge. At its insertion it crosses the long tendon of the biceps, with which it is in general partly continuous ; occasionally it is split into two parts—one extending to the neck of the capula, the other continuous with the biceps tendon. In frequency I have found this structure as constantly present as the spino-glenoid liga- ment, than which it is often much stronger ; and from observations extend- Ing over several sessions, I have estimated that in the average of every twenty subjects it occurred very strong in five, weak but distinct in seven, indistinct in five, and absent in three. Its strength I have found 468 to vary within considerable limits; in one instance it was capable of sustaining a weight of sixteen pounds; in the majorityof other cases it could not support a pressure of more than three, four, or five pounds, and sometimes it was not sufficiently strong to bear a weight of six ounces. The second ligament to which I would call attention is a third acces- sory slip to the capsule of the hip joint (Plate IV., fig. 2). I have usually found this band springing from the upperand onter part of the tuberischiu; its fibres ran outwards, backwards, and a little upwards, crossing over the groove which separates the acetabulum from the tuber ischii, and are inserted into the posterior aspect of the neck of the femur about midway between the trochanters; a ridge sometimes exists in this position; here its fibres are inseparably united to those of the capsular ligament, although comparatively distinct at the ischiatic attachment. This structure is brought into view by raising the gluteus maximus, by reflecting the sciatic vessels and nerves, cutting through and throwing down the qua- dratus femoris ; and then, when we divaricate the gemelius inferior from the obturator externus, it can usually beseen. Its lower fibresare traceable along the upper edge of the tuber ischii, and sometimes are connected with the origins of the hamstring muscles : it is separated from the origin of the semimembranosus by the attachment of the quadratus femoris. Two other accessory ligaments are recognised in connexion with the hip joint— ilio-femoral and pubio-femoral—but this ischio-femoral fasciculus is usually as distinct from the capsule as either of these, and isoften much stronger than the last-named; it protects the joint in rotation inwards, EXPLANATION OF PLATES TO ILLUSTRATE DR.

My observations on the muscles of the Marsupials were made on four Kangaroos, an Opossum, and a Phalanger, which died in the Zoological Gardens of Dublin. One of the Kangaroos was the Giant Kangaroo, a female, which had lived for nine years in the Zoological Gardens, and died in January, 1866, after a fortnight’s illness, of paraplegia, produced by cold and damp. The other Kangaroos were Wallabys, two female and one male, which died in 1865-66, of scrofulous disease of the lower jaw, presenting similar symptoms in all, and apparently pro- duced by the damp climate of Dublin, from the pernicious effects of which no care seemed sufficient to protect them. The Opossum (female) was from Virginia, and died in January, 1866, and the Phalanger died in 1864. The stomach of the Opossum contained thirty-four lumbrical worms. Part J. —KaAnGARoos.

IL. quadratus femoris, ayy setae oat rl sAicoz. ab sine, HeleO2 ”? : ; 4 - ec 0h welts This is one of the most remarkable muscles found in the Kangaroos, and is intended to assist in the support of the animal when resting in its usual attitude, on the tail and hind legs. It takes its origin from the large triangular surface of the ischium, Fig. 25 (q. f.), and, thence converging in a pyramidal mass to a point, is inserted into a special tro- Fig. 25. chanter or tubercle, developed for its reception in the middle of the posterior surface ofthe femur. Fully two-thirds of this pyramidal mass are composed of tendinous fibres, the remaining third being muscular, so that the whole may be regarded as an elastic tendon. When the animal sits upon its tail and legs in the manner above described, it places its feet so far forward, and its tail so far back, that a mechanical observer is at once struck by the apparent want of strength of the arch on which the weight of the body is supported, and is disposed to come to the con- clusion that the act of sitting on its tail must be a fatiguing one to the Kangaroo. Observation of their habits, however, abundantly proves the contrary, and shows that the animal prefers this attitude to any other. 472 The explanation of the difficulty is to be found in the semimembra- nous guadratus femoris, which acts as a ‘‘ tve-beam’’ to the arch, and, without much expenditure of force, supports the weight of the body placed on the vertex of the straddling arch formed by the tail and hind feet. I do not know of any other animal in which the insertion of the quadratus femoris is placed so low down on the femur, nor of any in which, as in the Kangaroo, a special RUE NE TSE is provided for this muscle. 9.0, agitator caud@, ¢ 1.

No. X.—Movscvrar Anatomy or THE Emu (Dromeus Nove Hollandie), I am indebted to the kindness of Mr. Thomas Moore, Curator of the Derby Museum, of Liverpool, for the opportunity of dissecting a fine male specimen of the Kmu (Dromeus Nove Hollandie). This bird was sent to me from London (1865); and, having reached Dublin two days after death, was quite fresh, and in ‘fine condition for dissection. On inspection it presented tubercles of the liver (Farre’s?), an enormous developement of omental fat, and fibrinous clots, partly melanotic, in all its arteries. T had also, through Professor Huxley, applied to the Council of the Zoological Society of London, for permission to dissect the muscles of the Ostrich, Emu, or Cassowary, in case such birds should die in their Gardens, and their bodies not be more favourably disposed of. In con- sequence of this application I received, 27th of April, 1866, the second Emu described in this note, which proved to be a larger and finer bird than the first; and I beg leave to take the present opportunity of re- turning my thanks to Professor Huxley, to Dr. Sclater, and to Dr. Murie, of the London Gardens, for the kindness with which they aided me in my attempt to procure specimens of these rare birds for the pur- poses of scientific research.

XVI.—On tHe Muscutar ANATOMY OF THE RHINOCEROS. A youne male Rhinoceros, three years old, having died in the Zoolo- gical Gardens of Dublin in April, 1865, the body was purchased, for £17, for the Museum of Trinity College, and I availed myself of the oppor- tunity of making a careful examination of his muscles. I was ably assisted in the dissection by Mr. Macalister, Demonstrator in Anatomy of the Royal College of Surgeons, and by a staff of medical students, who relieved each other from time to time. The stench from the de- composing blood was almost intolerable, and several of my assistants were disabled by typhoid diarrhoea; this I escaped myself, as I had done on a former occasion when dissecting a Nylghau, which had died of putrid fever, and whose blood after death seemed to communicate di- arrhoea by its smell to almost every person in contact with the body. Notwithstanding these difficulties, I was able to complete the entire muscular dissection in person, the results of which cannot fail to prove of interest to anatomists. Having made a careful post-mortem examination of all the viscera, except the brain, I felt it my duty to lay the following Report before the Council of the Zoological Society :— ‘‘ScHOOL oF Puysic, TRinITy COLLEGE, “ Dublin, April 14, 1866. *¢ Report on DEatH oF THE RHINOCEROS. ‘«The Rhinoceros died at 4 a. Mm. on Thursday, the 6th inst., and his body was opened in the new aerate Room of Trinity College on the 8th inst., at 1 P.M. 516 ‘‘T was assisted in making the post-mortem examination by Pro- fessor Ferguson and Mr. Connor ; there were also present Dr. Alexander Carte, Dr. M‘Dowel, Dr. Bennett, Dr. Macalister, and several other ana- tomists. «The rectum was protruded through a space of eighteen inches, and in it were two post-mortem ruptures; in the ilium, two feet from the cecum, there was extensive softening, as also at the junction of the duodenum and jejunum; the stomach was filled to distention with a mixture of hay and whole Indian corn, both fermenting, and pervaded with an aldehydic smell, which overcame even the intolerable odour of the gases with which the abdomen was distended almost to the bursting point; the hay was somewhat masticated, but the corn had been bolted whole ; numerous tapeworms were found in the upper part of the intes- tines. ‘The decomposition set in with most unusual rapidity, parti- cularly in the anterior extremity, and it was with the greatest difficulty that a few precious fragments of the viscera of this rare animal could be preserved; many of the muscles also dissolved in the course of twenty hours into a mass of putrid jelly. This phenomenon was most marked in the left side of the thorax and left anterior limb. ‘* CAUSE OF DEATH. ‘‘T believe that death was caused by the improper administration of Indian corn, which fermented in the stomach and intestines, and deve- loped gas to such an extent as to cause prolapsus of the rectum, and that the pressure caused by this gas ultimately destroyed the action of the diaphragm, and so caused death by asphyxia; and I am further of opinion that itis the duty of the Council to institute the most searching inquiry ito the manner in which Indian corn was given to this animal, as such food does not appear in the scale of dietary formally prescribed by the Council’s order to be used.

In the Falcon and Cara it takes origin from the transverse process of the large terminal caudal vertebra (plough- share), and is inserted into the second fifth from the top of the linea aspera by means of a flat tendon; in the Goose it is inserted into the middle of the lower part of the gluteus medius ; and in the Duck into the outer head of the fibula. 4 The giutcus maximus in the Falcon and Cara takes its origin from the edge of the ilium, in a plane below that of the zen. vag. fem., for one-fourth of an inch in front of the acetabulum, and has the usual insertion ; in the Crane its origin is from the post-acetabular edge of the ilium, and it is in- serted by a broad tendon into the middle of the vastus exiernus and fascia of the outer side of the thigh; and in the Goose it is inserted into the fascia of the inner side of the knee. © The gl. medius has the usual insertion in the Falcon, Cara, and Crane; butin the Goose and Duck it isinserted into the middle of the linea aspera. f Quite separate in the Crane; gl. min. = 0°01, gl. quartus = 0°03. § This small muscle, in conjunction with the savtorius, in most birds serves instead of a rectus fe- moris. h The biceps femoris in the Falcon, Cara, and Crane, passes through the usual tendinous pulley at the outer side of the lower end of the femur, and outer head of the gastrocnemius ; in the Goose and Duck itis inserted inte the tibia, at the inner side of the knee. i These muscles in the Falcon and Cara are inserted by flat tendons into the tibia; and in the Crane they are also inserted into the upper tendinous portion of the inner head of the gastrocnemius. k This muscle, in the Falcon and Cara, takes origin from three-fourths of the length of the pubis behind the acetabular prominence of that bone. 1 There is a rectus femoris in the Falcon and Cara, arising from the ilium, in front of the acetabular prominence of the pubis; itis a fine delicate muscle, weighing 0-01 oz. in the Cara, and its tendon passes obliquely across the front of the knee joint from within outwards, and, winding down into the calf, forms one head of the jirst perforate flexor of the second toe, the muscular portion of which is con- nected by muscular slips with the jirst perforate flexors of the third and fourth toes, and with the second perforate flexor of the third toe. The weight of the jirst perforate fiexor of the second or index toe in the Cara, was 0°02. This muscle is thus described by Cuvier :— “Tly a dans le lieu qu’occupe le pectineux des quadrupedes, un petit muscle gréle, quise prolonge jusqwau genou. Son tendon passe obliquement pardessus, et se glisse derriere la jambe pour s’unir¢ au fléchisseur perforé du second et du cinquiéme doigt.’’* Professor Owent regards this muscle as the gracilis ; while he considers as rectus femoris the muscle already described as tensor vagine femoris. * “ Lecons d@’Anatomie comparée,” tom. i., p. 359. + ‘* Cyclopedia of Anatomy,” vol. i., p. 296.

Wixpez, M.D., Vice-President, in the Chair. John Barrington, Esq., D.L.; John Casey, Esq.; and William Frazer, Esq., were elected Members of the Royal Irish Academy. The Rev. J. H. Jeniert read a paper On a FLurp possessing Oppositrn Rotatory Powers FoR RAYS AT Opposite ENDS OF THE SPECTRUM. He commenced by alluding to the construction of an instrument which he had exhibited and described to the Academy some time ago.* The purpose of this instrument is to measure the rotatory power of a trans- parent fiuid, not directly, but by the method of compensation. For this purpose the ray of polarized light, before} its passage through the fluid under examination, is transmitted through a fluid of an oppo- site rotatory power; and the construction of the instrument provides a method of varying and measuring with exactness the length of the column of this latter fluid through which the ray passes. The fluids used for this purpose were, in general, the two well-known species of oil of turpentine—namely, that which is obtained from the Pinus maritima of the South of France, and that which is obtained from the Pinus Australis of North Carolina. The former of these, being a left-handed substance, is used in the examination of fuids which, like the solution of cane sugar, are right-handed ; and the latter, being right-handed, for those substances which, like the solution of quinine, and the great majority of fluids possessing the rotatory power,| are left- handed. A means is thus obtained of comparing the rotatory powers of all fluids for which the rotation is in the same direction ; but, in order to compare those whose rotatory powers are opposite, it became neces- sary, in the first place, to ascertain the relative rotatory powers of the * “ Proceedings,’”’ vol. viii., p. 279. + The order of transmission is indifferent, but the construction of the instrument re- quires that the light should pass first through the compensating fluid. t So far at least as the author has examined them. ool two standard fluids. This was, of course, to be done by compensating with one of these fluids the effect produced by the other. When this is done, it is plain that the length of the columns of the two fiuids through which the light passes will be inversely pr oportional to their rotatory powers. The author did not anticipate any difficulty in effect- ing this compensation; for, inasmuch as the two species of oil of tur- pentine, chemically identical in their composition, differ very slightly in their refractive and dispersive powers, the law assumed by Biot would lead us to expect that the rotations produced in the planes of polarization of any two homogeneous rays should be in nearly the same ratio in each of these fluids. If this were true, the ratio of the lengths of equivalent columns of these fluids should be nearly the same for all the rays of which white light 1s composed; and therefore, when these columns are so proportioned that the entensities of the light in the two images* are the same, the tints will also be the same, so that there should be no difficulty in making the experiment. The actual result, however, was wholly different from that which the law of Biot had thus led the author to anticipate. So far from giv- ing a tolerably perfect compensation, the two species of oil of turpen- tine compensate each other more zmperfectly than any two substances which the author has examined—in fact, it is scarcely possible to make the experiment at all. When the lengths of the columns of fluid are so adjusted that the intensity of the light shall be the same in the two images,t the tints are found to be wholly different. The left-hand image shows a very brilliant sky-blue, and the right-hand image an equally brilliant rose colour; the beauty of these colours is very re- markable. There is, therefore, plainly a deficiency of red ight in the left-hand image, and a deficiency of blue light in the right-hand image. In seeking to interpret this appearance, it is to be remarked that when the light passes through a single fluid whose rotatory power is not very great, left-handed rotation is indicated by the darkening of the left-hand image, and right-handed rotation by a similar effect produced in the right-hand image. Assuming, then, that, in the compound effect produced by transmission through the two columns, the rotation is compensated, or in other words reduced to zero for the mean ray, it is plain that this effect will be left-handed rotation for the red ray, and right-handed rotation for the ray at the other extremity of the spectrum. It is evident, therefore, that the right-handed or Carolina turpentine rotates the plane of polarization of the red ray /ess, and that of the blue ray more than the left-handed or Bourdeaux turpentine. The Carolina * “ Proceedings,” vol. vii, p. 349. + So far at least as this can be effected; but the truth is, that it is almost impos- sible to compare with any tolerable degree of accuracy the intensities of light whose colours are so different. Even readings taken by the same observer will not agree with each other, and the personal equation will obviously be very large. Do2 turpentine is, therefore, more dispersive of the planes of polarization than the other. In reasoning on this experiment it occurred to the author that a similar effect ought to be produced if the ray of polarized light, instead of passing successively through two columns of French and American oil of turpentine, were transmitted through a single column, composed of a mixture of these two fluids. As they are identical in chemical com- position, it did not seem probable that any chemical action could take place; and therefore, in accordance with the principle found to hold good for mixtures in general, the effect of two columns of fluid, when mixed together, ought to be the sum of the effects which they produce separately. If, therefore, the lengths of the two columns be such that they compensate each other for the mean ray, the fluid produced by mixing them together ought to exercise a left-handed rotation on the plane of polarization of the red ray, and an opposite effect upon that of the blue ray. This anticipation was fully realized by the actual experiment. Some difficulty was found in ascertaining experimentally the exact proportion in which the fluids should be mixed together. The source of this dif- ficulty is, as has been before stated, the impossibility of comparing with exactness the intensities of lights whose colours are different, and therefore of ascertaining the ratio of the lengths of two columns which compensate each other for the mean ray; and a small deviation from the true proportion will render the rotation produced by the mixture either wholly right-handed, or wholly left-handed. : The best method of ascertaining this proportion is to measure suc- eessively the actual rotations produced by each kind of oil of turpentine in the planes of polarization of the red and blue rays. Let F', be the rotation produced in the plane of polarization of the red ray by the column of Bourdeaux turpentine; /, that produced in the plane of po- larization of the blue ray, and 4,, A,, the corresponding rotations pro- duced by American turpentine; then, if m be the quantity of French turpentine in the mixture, and n the quantity of American turpentine, the mixture will be right-handed for the red ray (and therefore @ for- tior¢ for all the rest), if on the other hand the mixture will be left-handed for the blue ray, and therefore for all the less refrangible rays, if and if the value of ~ be intermediate to these two values, the fluid is pos- i sessed of double rotation. The phenomenon is rendered most striking by giving to the two fluids in the mixture such a proportion that the left- SS Pa oe z o393 handed and right-handed rotations may be equal to each other. If this be so, we shall have - mE,—-nA,=nA, - mi; whence Mm Ay, + A, th Be Ht In order to measure exactly the quantities A,, A,, F,, /, it was necessary in the first place to obtain rays as nearly homogeneous as pos- sible. This was easily effected in the case of the red ray by transmitting a solar beam successively through blue and red glasses—this combina- tion, as is well known, only permitting the extreme red ray to pass. It is not possible to obtain so homogeneous a ray at the other extremity of the spectrum ; but the condition is very approximately fulfilled by trans- mitting the ray through a solution of sulphate of copper supersaturated vith ammonia. The light transmitted by a sufficient thickness of this fluid, though not homogeneous, is almost entirely composed of rays si- tuated at the violet end of the spectrum, the red, orange, and yellow rays being nearly extinguished. The following were the values obtained for a column of each fluid whose length was four inches :— A,= 6° 58, a oon OU k F. =19° 45’, F, = 61° 230 Hence we find ae gar n When a mixture made nearly in this proportion was traversed succes- sively by solar light which had passed through a combination of red and blue glass, and by light which had passed through a sufficient thickness of the ammontiacal solution of sulphate of copper, the effect was very striking. With blue light, the Jef¢ side of the spectrum was almost quite black, while the right side was a bright violet-blue; with red light, the right side of the spectrum is nearly black, and the left side a bright red. This appearance indicates that the fluid, through which the light has been transmitted, is left-handed for the red ray, and right-handed for the blue and violet. The actual rotations are— Mor redvlight, (27k = 19K 5), Kor blueheht i. vo + 1° 66 5 the mixture containing 67 parts of American turpentine, and 33 of French turpentine. The ratio in which the two species of oil of tur- R. I. A. PROC.—VOL, IX. 4a ‘ 534 pentine should be mixed, in order to produce this phenomenon, must be understood to apply only to the particular specimens examined; for the rotatory power of oil of turpentine will be found to vary with the specimen used, and also to some extent with the number of distil- lations to which it has been subjected. ‘To insure success, this ratio must be determined by actual measurement for the specimens of oil of turpentine examined. A certain amount of difficulty attends this mea- surement, arising from the impossibility of obtaining a homogeneous blue or violet ray of sufficient intensity for the purpose of the experi- ment. Hven when transmitted through a strong solution of sulphate of copper supersaturated with ammonia, the beam will still contain a considerable mixture of rays of different refrangibilities. The ro- tations A,, /,, cannot therefore be measured with perfect accuracy. It is possible, also, that, if the specimens of turpentine be not very pure, there may be some chemical action between the two fluids which will cause the rotation to vary. There may thus be a certain amount of discrepancy between the observed and calculated results in the case of the mixture.

Mr. Dents Crorton read the following paper :— On Vestices or Ancient Human Hasitation 1n Pootr’s Cavern, DERBYSHIRE. Pootr’s Cavern 1s an enormous natural excavation in the Carboniferous Limestone of Derbyshire, running for several hundred yards under a hill, about half a mile from Buxton. It is said to derive its appellation from an outlaw named Poole, who is traditionally reported to have made it his place of refuge in the reign of Henry VI. The entrance is very small, and for some distance a man of ordinary height must go into it in a stooping posture. The cave then enlarges, and expands into a capacious passage, with numerous stalactites depending from the roof. It bears marks of having been subjected to the action of water at some former period, there being for a considerable part of the length, on top of the limestone floor, a layer of gravel, about three or four feet deep, covered over by one of brown clay, having a somewhat greater thickness. At the distance of perhaps thirty or forty yards from the mouth of the cavern the widening of the passage suddenly increases on O37 the right hand from the entrance, and leaves a sort of semicircular recess, in which were exhumed the remains upon which I found the opinion that the cave must originally have been the dwelling place of an ancient race of men. These relics were found under the following circumstances :-— In the month of August last, the proprietor, having determined upon making explorations for the purpose of finding out what might be hidden from superficial view, set men to break up the surface, at the distance of a few feet.from the side of the cavern, in the before-mentioned recess. As this operation was at the top of both the gravel and clay, it was at the height of some seven or eight feet above the natural floor of the cave. Nearly at the surface, and only slightly covered over, the workmen came upon a layer of stalagmite, of varying thickness, but averaging about three quarters of an inch. After this had been broken through, there came a layer of the brown clay, about ten inches or a foot deep. Below this was another layer of stalagmite, thinner than the upper one, and averaging perhaps an eighth to half an inch thick. When this in its turn had been broken up, there came again about ten inches or a foot more of the brown clay, and then a quantity of bones compacted within a small space, and mingled with fragments of broken pottery, and charcoal, but without flint implements. I was not myself present during the excavation, but upon hearing of it went into the cavern, and made a personal examination of the place, when I found no reason to doubt of the facts having been as described. I also disin- terred im situ, with my own hands, some pieces of bone which had escaped the first explorers, and brought away some of the charcoal. I further procured a selection of the first found bones, and pieces of pottery. All of these, as well as specimens of the two overlying layers of stalagmite, you may now see before you. One of the pieces of pot- tery discovered had a sort of rhombic ornamentation figured on what had been the outside of the vessel. The bones are all of animals such as would be used for human food, and there are none human, of carni- vora, or extinct species; they comprise remains of the cow, goat, and pig tribes; I am not yet, at least, aware of the existence of any other. There is not, so far as 1 know, a trace ofany of them having been split up for the purpose of extracting the marrow. Upon one bone—an astragalus—an adherent layer of stalagmite has formed. Tt is a matter of importance to find out what evidence the organic remains give upon the subject of their own antiquity, and whether this be in any degree confirmatory of what might be surmised from the circumstances under which they were found. The outsides of the bones are to a certain extent decayed and discoloured; and some are light, whilst others are comparatively heavy, which might lead to a suspicion that the latter had been infiltrated with some weighty sub- stance. There are but two such at all likely to cause the phenomenon in question under the circumstances; namely, iron, and carbonate of lime. Accordingly, some portions of the bones which appeared to be heavy have been boiled in hydrochloric acid, and treated with ferro- 538 cyanide of potassium, as a test for the existence of the former; and these in the reaction yielded a distinctly blue colour, thus showing evident traces of iron. A fresh beef bone subjected to the same process, for the purpose of comparison, only gave an extremely light tinge of blue. It was thus clear that the cavern bones contained more iron than one perfectly recent does. The question then arose as to whether the infil- tration were only superficial, or permeating the substance. This was solved by sawing some of the heavier bones across. During the opera- tion they gave out a strong organic smell; and the sections showed plainly that a large amount of the original organic matter was retained, whilst any decay of gelatine had been chiefly from the outsides, more . spongy parts, and fractured surfaces. This also proved that the bones had remained unsaturated with carbonate of lime, or other foreign mineral matter. We must therefore conclude that the iron impregnation was only superficial, derived from the enveloping ferruginous clay, and that the difference in comparative weight must be referred mainly to the greater or less loss of gelatine. Upon the whole, these bones must rather be referred to the class ‘‘recent,’”’ than that of ‘‘subfossil.”’ The existence of the charcoal and pottery along with the remains leads us to the conclusion that the place in which they were found was used for cooking by the ancient Troglodytes—that the charcoal survived from their fires, and the pottery from their rude culinary utensils. Upon taking a general view of the facts, I am inclined to consider the deposit in the light of what the Danish antiquaries have designated as a “‘ Kjokkenmodding,” or ‘‘ Kitchen dung”’ heap. As to the antiquity of the bones it is very hard to give a conjecture ; and opinions on these matters, where there is little proof, should always be formed with great caution, and put forward with diffidence. There is, however, one thing which may possibly throw some light on this point, as a matter of circumstantial evidence, and it is the following :— That about four years ago a fibula, and two coins of the reign of Trajan, were found at the opposite side of the cavern, a little further on in it than the bone deposit, at the height of about four inches above the gravel, and in the clay. These 1 have seen, and have no reason to doubt their genuineness. But there is no evidence as to when or how they got to the place in which they were discovered; and, as there was no stalagmite overlying them, there is nothing determinative of at least a certain degree of antiquity for the time of their embedding. It is right, however, to mention this circumstance, from its possible bearing on my subject. If we allow to it some weight, and combine it with the comparatively recent character of the bones, I think that a period about that of the Roman dominion over Britain may be fairly accepted, provisionally at least, as that of the time of the deposit. This takes it unquestionably out of the domain of geology, strictly speaking, but relegates it to that of archeology. | Tt is an interesting fact to find that one of the great Derbyshire caverns, like several others which have recently come to light both in 039 Hingland and on the Continent was anciently appropriated as a place of human habitation. The following donations were presented :— The Marquis of Kildare presented a MS. copy of the “‘ Book of Post- ings of the Forfeited Estates in Ireland, A. D.1701.” Dr. W. D.

Dr. Thomas Hayden read a paper “On the Physiology of Protrusion of the Tongue, and its Deviation to the Affected Side in Unilateral Pa- alysis.” Mr. Evernr A. Conwe tt read the following paper :— Has roe Lia Farr on Tara Hitt Been Inscripep ? So much has already been written about the obelisk on Tara Hill, but more particularly by the late lamented Dr. Petrie, to prove that it is the veritable Lia Fail, or Stone of Destiny, on which the Irish kings were formerly crowned, that it is with a certain amount of well-felt _diffidence I venture to draw attention to this stone in a new light, and to head this communication with the foregoing question. It is well known that its present position in the great oval enclosure of the Rath na Riogh, or the King’s Chair, is not its original one. During the current century it was removed from an adjoining tumulus, called Dumha-na-Ngiall, or the Mound of the Hostages, where it pre- viously lay, and was erected as a headstone to the grave of thirty-seven insurgents who were killed in a skirmish with the military at the battle of Tara in 1798. On the 18th of last month (May, 1866) I paid a visit to Tara, and made an examination of thisstone. It stands five feet over ground; and from subsequent examination, on Saturday last, I found that it was sunk a foot and a half in the earth, the entire height or length of the stone being 63 feet, and its girth 4 feet 10 inches.* I was at first struck by finding two * The late eminent Dr. Petrie, in his celebrated essay ‘‘ On the History and Anti- quities of Tara Hall,” published in the ‘‘ Transactions of the Royal Ivish Academy,” 540 lines cut into the south-east face of the stone, which overlooks “‘ The Croppies’ Grave’ (as itis familiarly called), each line being 14 inch long, about an inch asunder, and cut or furrowed out, in V-shaped fashion, to the depth of about three-eighths of an inch, On the top of the pillar, which is rounded off, can still be traced the remains of four cup-like hollows, in their present appearance rudely dug into the stone. Other portions of the pillar also afford evidences of similar cup-like hollows. The stone itself, which is a pillar of very fine-grained granite—a rock not belonging to the locality, and which consequently must have been imported here—appears to me not to have been originally a round pillar, asits present aspect might suggest, but a quadrilateral stone, whose edges have been worn off by attrition and the action of the weather. - On Saturday last June 9, 1866), I paid another visit to Tara; and having dug round the base to the extremity of this stone, I found that on the same face which contained the two inscribed lines before men- tioned, for a foot in height, the surface was quite smooth and flat across the entire face of the stone; and on this portion of it were two lines cut, as seen in the rubbing, and a third line ending in a cup hollow. The fact of this portion ofthe stone, now sunk in the earth, having been found to be quite smooth, leads me to suppose that the entire surface of the stone was originally the same, and contained characters engraved upon it. On the opposite side of the stone, now its north-west face, and near the bottom, are to be found three other lines, whether or not owing to the action of time, assisted by a natural fracture in the rock, is a point which I trust some one more competent may hereafter clear up. 3 From the fact of the principal cuttings which I have observed on this stone overlooking immediately ‘‘ The Croppies’ Grave,’”’ where it has in recent times found a site, I infer that those who placed it there must have observed, and acted on such evidence, that this face of the stone contained something more of interest than any of the others. The stone itself, although it may have been originally covered with hieroglyphics, from being of rather a soft and friable nature has in course of time lost those inscribed records, which might have settled the question of its identification as the real Lva Fal. vol. xviii., p..161 (1837), writing of the Lia Fail, has fallen into two mistakes regarding this stone—one, as to its material being limestone ; and the other, as to its dimensions, which are overstated. His description is :— “ The material of which this monument is composed is a granular limestone, very pro- bably from some primary district; but whether it be Irish or foreign has not been ascer- tained; it may be remarked, however, that no granular limestone occurs in the vicinity. The stone is at present but six feet above ground, but its real height is said to be twelve feet.” : 541 Mr. Everne A. Conwett read the following Paper :— On an Inscripep CromLEAc NEAR RatHxKenny, Co. Mearu. Ar page 105 in the late Dr. O’Donovan’s manuscript letters, contain- ing information ‘‘relative to the antiquities of the county Meath, collected during the progress of the Ordnance Survey in 1836,” refe- rence is made to a very remarkable cromleac in these words :— ‘‘Near Rathkenny House are two large stones, which, though de- scribed in Name Book, p. 23, as part of a cromleac, are not known, how- ever, by that name among the people. They are sometimes called large stones, and are said to have been thrown from Tara Hill by Fionn Mac Cumhail.”’ From the fact of the stone which forms the subject of the present notice being about twenty tons in weight, and its distance from the Hill of Tara, in a northerly direction, about eighteen statute miles, the correctness of the above information may be very fairly doubted. This— improbable, nay, impossible as it is—is all that the country people, up to the present day, can tell you respecting the remarkable memento of very remote ages which still exists at Rathkenny. Seeing mentioned on the Ordnance Map of the district about Rath- kenny, which is a village lying four miles N. W. from the town of Slane, what is there marked as a ‘“‘ Druid’s Altar,” I had the curio- sity to visit the place on the 27th February, 1865 ; and I was astonished to find that the singular and elaborate inscriptions on this cromleac had not attracted previous notice. On the 11th March following I spent several hours in a fruitless attempt to get a good rubbing of the upper surface of the slab, although E succeeded in taking accurate rubbings of seven circles on the under side, and of seven other circles picked on the opposite face of the single upright stone against which it leans. The circles on the under surface are not on, or about, the middle of the large slab, but nearer to the lower edge of the stone, which rests upon the ground, than to the upper portion of it. In Plate X., fig. 1, their relative positions are shown, the circles being nearly one-twelfth of the actual size. The single upright stone against which the cromleac slab rests stands about four feet over ground, is four feet broad where it emerges from the ground, tapers slightly as it ascends, and varies from eighteen mehes to two feet in thickness. The interior face of this supporting stone presents the appearance of having been picked all over with minute hollows for the purpose of ornamentation ; and the seven circles hollowed out on this face are grouped in the manner shown in Plate X., fig. 2, being there represented nearly one-twelfth of their actual size. The construction of the circles is rude and irregular, formed by lines about half an inch in breadth, and about a quarter of an inch in depth, which appear to have been picked out of the stone with a metallic im- plement. PROC. R. I, A.—VOL. IX. 4B 542 Plate XL., fig. 4, is a representation of this unique monument, as it stands on elevated ground in the centre of a green field called Capndn cull, i.e. “the little carn of hazel’—the name, no doubt, originally applied to the cromleac itself, from having some hazel trees formerly growing round it, but which afterwards extended to the field.* It is 272 yards in an easterly direction from the residence of H. H. Hussey, Esq., the proprietor of the estate. The large flag itself measures ten feet ten inches long, eight feet six inches broad, and is three feet thick, with one edge resting on the ground, and the other upon the upright or supporting stone before described ; it is inclined to the horizon at an angle of 37°, and faces N.N.E. Both stones constituting this monument consist of the natural bed surface of lower Silurian rock, greenish grey calcareous grit, slightly micaceous, which is found in abundance in the neighbourhood. In the month of August last my friend Mr. Du Noyer accom- panied me to Rathkenny, and made a very careful drawing of all the characters on the upper surface of the slab, which I was previously un- able to record by means of arubbing. To secure extreme accuracy we divided the face of the stone into square feet, by transverse lines of white twine, fastened on the extremities of the stone by ordinary shoe- makers’ wax. Having paper ruled off in square inches, there was no difficulty in making a correct transcript of the entire face of the stone, the characters on which will be more intelligible from an examination of the drawing than any words could make them (Plate XIL., fig. 5). It will be observed that there are upwards of three hundred depres- sions, or cup-shaped hollows, which, although in several instances they take the form of grouping, may be merely the result of weathering, and not artificial. Having been so long exposed to the wasting action of the weather, it would now be hazardous to pronounce with certainty upon this point. Itis, however, very remarkable that all these de- pressions are distinct from, yet interspersed with, the singular collection of inscribed lines which cover the face of this stone. These lines, con- sisting of upwards of ninety separate characters, still exhibit the ori- ginal clean and smooth cutting—for the most part in a triangularly shaped hollowed line—some to the depth of nearly a quarter of an inch; and are, to all appearance, the delicate workmanship of some sharp metallic tool, bearing a strong contrast in style of execution to the rude sculpturing of the circles. I am not presumptuous enough to make any attempt at offering an explanation of the reading or meaning of these mysterious characters, yet I am not without hope that a key to their interpretation will be found, and I trust at no very distant day. Wecannot but admire the perseverance and success of philologists in developing affinities in the languages of various nations from the shores of the Pacific to Western * It has also been supposed that the name may have reference to the local tradition, and may mean ‘‘ the little carn of Finn Mac Cumhaiill.” 543 Europe. Over the same vast region there is often a particular, and always a general, resemblance in the megalithic memorials which have come down to us from unrecorded ages. ‘The similarity of popular tales, legends, and superstitions will also show the early connexion of the ancestors of many nations which are now geographically remote. Nearly two thousand years ago Pliny has recorded the similarity of the magical arts of the British Druids and the Persian Magi; and we are all familiar with the close resemblance between many of the Irish and Oriental popular superstitions and beliefs. That the characters en- graved on this cromleac are Oriental, I have little doubt ; but, not being an Oriental scholar, I commit the task of pursuing the investigation to those competent to deal with such a question. Although inscribed cromleacs have hitherto received little attention from antiquarian writers and investigators, I trust the publication of this present notice may lead to a re-examination and comparison of all such remaining records of prehistoric times, wherever they are known to exist; and no doubt many such will be discovered by those who know what they may expect to find on cromleacs. Up to the present time, these ancient monuments have been exa- mined and classified rather in relation to the mode of their construction, &c., than with the hope of finding upon them incised records in lines, cup-like hollows, &c., which might lead to a fuller elucidation of their history. Since it is known that some of them at least contain such cha- racters, would it not be highly interesting that antiquaries, Im every country —in Asia, Africa, and Kurope—where cromleacs still exist, should most carefully examine them, for the purpose of comparing every record they may be found to contain ? Some clue to the reading of such characters may then turn up, as trustworthy as the celebrated Rosetta Stone* afforded to the interpreters of the hieroglyphics in the Pyramids of Egypt. About a year ago, the late John Windele, Esq., of Cork, sent me a sketch of the characters on an inscribed cromleac near Macroom, the similarity between which and that near Rathkenny is very striking. I regret I am not able to enter into fuller particulars respecting the Cork cromleac; but, not having seen it, I content myself with sub- mitting Mr. Windele’s sketch (Plate XI, fig. 3). * The Rosetta Stone, now in the British Museum, is a slab of basalt, about 3 feet long, and 24 feet broad. It was found near Rosetta, on the western mouth of the Nile, in the year 1800, and appears to have been placed originally in a temple dedicated to AtTum, by the monarch NecuAo. It exhibits three inscriptions, of the same import, — namely, one in hieroglyphics (some of which are lost by a portion of the stone having been broken off at the right-hand upper corner) ; another, in the Egyptian written cha- racter, called Demotic or Enchorial (this part of the stone being quite perfect); and a third, in the Greek language (a portion of which is also lost by a fracture at the right- hand lower corner of the stone). These inscriptions, furnishing the key to the decipher- ing of the Hieroglyphical and Demotic characters of Egypt, record the services which Ptolemy the Fifth (Epiphanes) rendered to his country. He is commended for his piety, his liberality to the temples, his victories, his remission of arrears of taxes and diminution of the imposts, and his protection of the lands by dams against the inundations of the Nile. He reigned between B.C. 205 and B.C. 182. p44 In our present state of archeological knowledge it would be almost idle to speculate as to the age of these monuments, or the people by whom they have been erected. By some they are called Celtic, and the. people who erected them Celts; while others hold that they have been raised by a people ethnologically different from the Celts—cromleac building and burying being a form of sepulture in all probability prac- tised before the arrival of the Celt, as it has been certainly followed in countries where neither Celt nor any other branch of the Aryan or Indo-European race ever penetrated; for we find such in Syria, aud along the northern coast of Africa. The race that erected cromleacs must have been much more widely diffused over the world’s surface than the Celtic, and in all probability that race existed in our own country before the Celts. Le Baron A. de Bonstetten, in his ‘‘ Essai sur les Dolmens,’’ published at Geneva last year, at pp. 5, 6, 7, &c., enters minutely into the classi- fication and description of the various kinds of existing cromleacs (dolmen being the word adopted on the Continent to signify what in the British Isles we call a cromleac). Unless we suppose the monu- ment near Rathkenny to be a eromleae in ruins, we cannot bring it under this most recent and carefully studied classification of such remains. If we adopt the meaning of the term eromleac, which probably has come to us through the Welsh, to be a@ leaning stone, or inchined stone, I am disposed to think that this monument near Rath- kenny is perfect as it now stands; that it never consisted of more than the two stones; and that this may be a type of monument not hitherto noticed or described. I am the more impressed with this be- lef, because up to about thirty years ago another slab, popularly re- membered as very similar, nearly, but not quite, as large as that just described, and facing in the same direction, existed in an adjoining field, at a point 275 yards south-east from the present one. What mystic characters it may, or may not, have contained inscribed upon it no one now can tell. The man—Christy Downey—-still lives, who, in his zeal for agricultural improvement, subjected this stone to the operation of blasting; and its debris were afterwards worked up into fences and drains. He states that in the act of blasting “‘ this stone was raised entire into the air for about six feet above the surface of the ground, and it then broke into pieces.”’ There was also a third ‘‘ big stone,” of still smaller dimensions, which he describes as lying quite flat, and about two perches to the east of the one just mentioned as destroyed. From what he sawin the destruction of the first stone he would not undertake to break or to blast this one, though less in size than the other. He therefore dug a deep pit on one side of it; and when in the act of prizing the stone into the pit, he says that ‘‘such a whirlwind came about my legs as asto- nished me; and I saw the effects of the wind on the surface for six or eight perches all round.” Under the centre of the stone, he states,’ ‘“‘ there was a cavity of about the size of a good pot, with black mould 045 in it, and a horseshoe on one side of the cavity, and a broken glass bottle on the other.’ Both horseshoe and bottle, I presume, found their way there in modern times. The subject of our present notice was also doomed; but, on the night preceding the day intended for commencing operations upon it, Christy strolled out from his cottage, and, looking towards the scene of his next day’s projected labour, saw a light i in the direction of ‘‘ the big stone,” there being low marshy ground in the neighbourhood im- mediately beyond. He returned to his home, and came to the wise conclusion, from all that he had seen, that it would be dangerous to interfere further with these ‘‘sacred stones.’’ So, after one of these primitive monuments having been blasted, and another buried, to the fortuitous appearance and the lucky intervention of the cgnis fatuus we are at the present day indebted for the preservation of the singular vestige of our nation’s early history which I have feebly endeavoured to lay before the Academy. Several raths or forts are in the Immediate vicinity; and tradition states that there are also several subterranean caves, which I have not had either the time or the opportunity to find out or to investi- gate. The Secretary brought up the following recommendation of Council :—- “That the sum of £50 be granted for the purchase of Antiquities, the arrangement and registration of articles in the Museum, and for other matters connected with the department of Antiquities.” The question having been put, it was moved as an amendment, by Professor Haughton, and seconded by Professor Jellett— *“¢ That it be recommended to the Council to omit all the words fol- lowing the word ‘ Museum’ ”’. A division being called for, it was found that ten members voted for the amendment, and twenty-three against it; it was therefore declared lost. The original motion was then put, and carried.

Edgeworth, Esq., and John O’ Hagan, Esq. Sir W. R. Witpz read the following paper :— On THE Battie oF Moyrtura. Tue author brought under the notice of the meeting the first of a series of communications he was about to make to the Academy upon the topography of the Battle-fields of Moytura, and the monuments still standing upon those memorable localities, and which were some of the earliest places referred to in the Irish annals. He mentioned that there were two battle-fields of this name, one was the northern or the ‘‘ Moytura of the Fomorians,” in the parish of Kilmacatranay, in the county of Sligo, adjoining the north-western end of the county of Roscommon, and extending from Lough Arrow to the strand at Ballysadare ; but with which he would not deal on the pre- sent occasion. The other, on the southern site, or ‘‘ Moytura Conga’ — of which Sir William exhibited a large map, and pointed out the dif- ferent localities on it—occupies the western extremity of the great plain at the junction of the counties of Mayo and Galway, ex- tending from the Fairy Hill of Knockmaha, near Tuam, to Benlevi, the first of the mountain range, which, rising from the waters of Loughs Corrib and Mask, gradually ascend and stretch into the Partry, Joyce Country, and Connemara mountains. This was the particular locality to which he proposed to call the attention of the meeting, and said he hoped on a future occasion to bring forward illustrations of the most remarkable of the very ancient monuments which crowd around the picturesque village of Cong, and occupy the northern sloping banks of Lough Corrib, and the eastern borders of Lough Mask. This great plain is nearly sixteen miles long, and the monuments occupy a space of about five miles in breadth atits western end. It was originally called Magh Nia, or Nemeadh, and in some works Magh Itha, before the celebrated battle from which it took its historic hame; but at present it goes by the Irish name of Ath Readh, or the unobstructed plain. Sir William said :— Prior to the date assigned by the Four Masters, A. M. 3308, for the battle of Moytura Conga, the entries in our annals are comparatively few, meagre, and of very doubtful chronology, and consist chiefly of notices of cosmical phenomena, colonizations, pestilences, the clearing of O47 the plains, the erection of forts, raths, and cashels, and the battle of Sleamhnai, Maighe Ithe, on the banks of Lough Swilly, in the county of Donegal, between the Fomorians, the possessors of the island at that period, and the newly arrived forces of Parthalon, the so-called Oriental or Grecian leader. The Firbolgs, or Belgze, so called from their assumed Belgic origin, next occupied the country, and established a Kingly Pen- tarchy. When the Tuatha De Dannan, who were a Scandinavian and decidedly a superior race, and who undoubtedly possessed a knowledge of metal, established themselves in the north-east of Ireland, they demanded a division of the kingdom from the Firbolgs; and a meeting took place between their respective ambassadors upon Magh Rein, on the shores of Lough Allen, near Slieve-an-Icrin, in the county of Leitrim; and upon the latter refusing to accede to this modest request, the Tuatha De Dan- nans marched westward, and, according to our histories, occupied the plains of Southern Moytura; and Nuadha, their king, with his staff, took up his position on the heights of Benlevi, from which a view can be obtained of the plains beneath to an immense extent, and a secure retreat preserved towards the fastnesses in their rere. The Firbolgs, under EKochy Mac Ere, their king, marched from Tara to the eastern end of the plain of Nia, where it rises into the picturesque hill of Knockma, now known as Castle Hacket, and where, according to the legends of the land, the Fairy King Finvarra (the Oberon of Irish Sylvan mythology) holds his court. From thence may be obtained one of the grandest views in Ireland. To the east, the great plain stretches beneath and around, from the hill of Knockroe to the towers of Athenry, or City of the Ford of the Kings, and includes the Tuam of St. Jarlath, the round tower of St. Benan, the beautiful abbey of Knockmoy, and the ruined keeps of the De Burgos—to the south, the ships riding in the Bay of Galway can be discerned in a clear day, and the Slievebloom and Clare mountains; and to the west the blue island-studded waters of Lough Corrib, and in the far western background the Connemara Alps, stretching from Lecanvre and Sheanapholia, with their clear- cut edges, and their sides momentarily varying in tints from the mar- vellous atmospheric effects of that region, round to the lofty peak of Croagh Patrick, and the bulky form of Nephin, and even some of the Achill mountains skirting Clew Bay, are all withinview. Certainly, if the son of Erc had an eye for the picturesque, or a soul for poetry, his patriotism should have warmed when he viewed the fair scene which was sought to be wrested from him by the invader. On the summit of Knockma an immense cairn of small stones has been erected over the remains of the female Coesair, the first of that great west- ern chain of similar monuments that stretch from thence to the valley of Maam, and finally abut upon the shores of the Atlantic near Renvyle. Around this cairn, in the month of May, the ground is literally blue with the flowers of the Gentiana verna. The battle is said to have been com- menced on the lith of June; it lasted four days, and ended in the defeat of the Firbolgs, and the death of their king, the pillar stone of whose ~ 043 son is probably the long stone of the Neale. Nuada, the Dannan king, lost his hand; and from the circumstances stated in the Bardic legends of an artificial arm having been supplied, he is ever after mentioned in history as ‘“‘ Nuad of the Silver Hand.’’ Whether Belor of the basilisk eye, another well-known character in our early tales, was at the battle of Southern Moytura is doubtful; but all the legends respecting the petrifying qualities of his eye, and even where he stood, &c., at the time of the engagement, are still related of the ‘‘Fothach Rua,” or ereat red giant. Fintan, the sage; Edena, the poet-prophetess; Dian- checht, the physician; Credne, the artificer; Gobnen, the smith; and all the Druid celebrities of early historic romance are said to have been at this battle. The site of the fiercest combat, and that which is still called Cath na Bunnen, or the Valley of ‘‘ The Battle of the Butts,’’ be- cause it is said that, the weapons of the belligerents having been injured, they fought with the butts, like the ‘‘ Faigh-a-Ballaghs’”’ of later days, is still pointed out. Several years afterwards the second battle, on the Northern Moytura, was fought ; and after it, as well as on the occasion of the previous defeat, the Belgze, or Firbolgs, fled for security westwards, and entrenched them- selves in those stupendous fastnesses of Arran, in Galway Bay—so that even then we see that the destiny ofthe Celt was Westward. But that they did not all go is manifest from the very marked characteristics of the two races, the dark and the fair, still remaining in the West. These few particulars and the foregoing brief sketch are worth men- tioning, inasmuch as heretofore some misconception has occurred, and some erroneous statements have been put forward by writers who have jumbled up the two battles of Moytura, although many years took place between them, and the intervening space from the Sligo to the Mayo locality is about fifty miles. Between the western slopes of Knockma, in the barony of Dunmore, to Shrule, and through the rich pastures of the barony of Kilmaine, the plain is studded with forts and circular raths, showing the early cultivation and comparatively dense population of that district. As, however,, we advance westward through the ba- rony of Kilmaine, over the great plain where the limestone crops out above the surface, in many places to the extent of several acres, the grass-grown circles are replaced by immense cairns, artificially con- structed caves, circles of standing stones, many of gigantic size, mono- liths or pillar stones, and great duns, cashels or stone forts, resembling some of those in Kerry and the Western Islands of Arran. All these accumulate, and finally culminate into a narrow space of about four square miles, the eastern line of which would run from the village of Cross to the Neale, and thence by Ballinrobe, to the western shores of Lough Mask, and the narrow neck of land between it and Lough Corrib to the waterport of Cong, where the wealth, taste, and liberality of our distinguished church restorer, Mr. Guinness, have done so much to beau- tify the landscape, to benefit the people, and to restore the crumbling columns of that Abbey, wherein was preserved the greatest artistic, as | | o49 well as the most historic memorial of piety and skill to be found in north-western Kurope—the Cross of Cong that now adorns our Mu- seum. About forty years ago, our great Petrie, in company with our bard and artist, Samuel Lover, visited this locality, and greatly regretted the obliteration of many of the monuments which he expected to find there. In 1838, O’ Donovan, then an officer in the Ordnance Survey, under our distinguished Academician, Sir Thomas Larcom—who for upwards of forty years has been more Irish and more useful than many of the Irish themselves—went over this locality ; but his observations thereon were not as full as might be wished. O’ Donovan, however, has left behind him what is even more valuable than a mere enumeration and identifi- cation of forts and cairns, in a translation, executed with that facility of diction in which he excelled, of one of those metrical histories which abound in our early literature, and which, although defective in the romance of the epic, ismore truthful in its history and topography than the ‘‘Tain Bo Cuilne;”’ but, like it, it was probably derived from varied and earlier sources than the times of the transcriber or collector. Having spent much of my youth in this memorable locality, where my ancestors sheltered the ecclesiastics who fled with the Palladium of the West, to which I have already referred, and having the honour to own a small bit of this battle-field myself, I have during my occasional visits to the country thoroughly investigated all these monuments on Southern Moytura; and, as an instance of what may be done by local investigation, | may mention that within the space of a single sheet of the Ordnance Map I was enabled to point out no less than twelve most interesting monuments previously unnoticed, consisting of forts, raths, stone circles, caves, lisses, and cashels, &c., all of which will be marked upon the new edition of that great work; and upon a future occasion I hope to be able to bring these and others in detail under the notice of the Academy. I may also mention that, through the kindness of my friend George Crampton, Esq., I have been supplied with a map and measurements of Caher-Mac Turk, the Dannan fort at Nympsfield, which was removed at the time of the building of the glebe house there, nearly fifty years ago: so that upon the whole we can even now enter upon the consideration of the battle-field of Southern Moytura with a fair _ prospect of success. The legendary lore and traditional accounts re- specting this and other battle-fields, and the events for which they were celebrated, have now almost ceased to exist. The locality can, how- ever, be recognised by the topographer, and the monuments thereon identified by the antiquary, while much of the old sagas may be culled from the popular superstitions of the district, or gleaned from the tale, surrounded as it is by all its incongruities, of the old Sennachie, whose language one understands, and whose feelings one reverences. Yet, although this traditionary and popular remembrance of the battle-field affords no more information than can be gleaned from similar sources respecting the raths of Tara, the monuments on the banks of the Boyne, BR. I. A. PROC.—VOL. IX. 46 590 the cahers of Arran, or the Round Towers, and several of the primitive churches, and even the Norman castles throughout the country, there are names attaching to this locality which serve to guide the painstak- — ing and skilled inquirer; and the ancient Irish annals, and some manu- scripts believed to be derived from very early sources, afford sufficient materials for attempting now, in the middle of the nineteenth century, an essay on a battle-field referred by our annalists to a period before the Christian era. To popularize Irish history, and familiarize our youth with incidents such as the foregoing, will tend to the mentakculture of the rising gene- ration, and the preservation of our national monuments; but until some Scott, or some one endowed with even a fragment of his genius; and combining, as he did, the knowledge of the antiquarian scholar, the deep research of the historian, the gifted tongue and feeling heart of the poet, the subtle wit of the humorist, the dramatic powers of the novelist, the knowledge of the popular superstitions and modes of thought of his countrymen, together with that rarest of all powers, the faculty of fus- ing fiction and fact, so as to weave a romance common to humanity with the historic incidents and characters of the past, we shall never have an opportunity, notwithstanding our much greater materials, for viemg with the literature of Scotland. Sir William R.W. Wilde exhibited plans of some of the subterranean chambers he had discovered, and quoted several of the early authors on the subject of Moytura. “He also said he intended dividing his commu- nications on Moytura into three portions—a general sketch of the battle-field, an historic aggount of the engagement, and a detailed de- scription of the monuments still existing thereon. Sir William R. W. Wilde brought forward, and made some remarks upon, his paper on the Plunket MS., descriptive of the civil wars in Ire- land, and styled ‘‘ A Light to the Blind,” which he had read to the Aca- demy on the 27th June, 1859. The following donation was presented :— A perforated stone found at an earthen fort, adjoining Kilbride pa- rish church, in the county of Wicklow: presented by J.S. Moore, Esq., of the Manor, Kilbride. Thanks were returned to the donor. The Academy then adjourned to the 12th of November. eR END dX. No. I.
