YOUR application for a copy of iny lecture for the pres iarh ; quassia and Ume'water. Some of these by giving contracti- lityt to the imbecile organ afford a short respite to his suffer- ings. They may moreover effect a transient but fallacious re- lief by forcing the concocting powers to squeeze their crude easiness, as sour erouf, she took the oppressive food out with her fingers, end washed out her stomach with water, and this always relieved her, and revived her appetite. Milk was observed to cnidle instantly, except when she liad darefully rinced out her stomach. In this case says Dr. Hclme, the coagulation did not take place, till after some time, for want he supposes of gastric liquor. The coagulation could be expedited by irritating the inner surface of the sto- mach with the finger. Asses milk was longer in coagulating than cows milk. The last coagulated in a few moments. Eggs, and cheese were quickly di- gested, hut not so soon as flesh meat. Vegetables in general vi^ere longer un- dergoing this process ; of these potatoes, and carrots passed off soonest.

A slcillfiil, honest physician, will say in such cases, — your cure can only be found in exercise. A ride with the cheerful scenery' of a new and beautiful country will give you healtli, vigour, and vivacity, sound sleep, and a keen appetite. But no drugs can act upon your blood and juices, like the joint force of all the mus- cles of your body, acting and reacting, as in a regular course o£ moderate exercise ; nor can any of our draughts and portions oxygenate your pulmonic blood, like the inspiration of the salufc^ ferous air of the mountains* " The first physicians by debauch were made j Excess began, and sloth sustains the trade. By chace our longliv'd fathers earn'd thtir food i Toil strung the nerves, and purify 'd the blood. But we their sons, a pamper 'd race of men. Are dwindled down to three score years and tea. Better to hunt in fields for health unbought, Than fee the Doctor for a nauseous draught. The wise for cure on exercise depend : God never made his work for maa to mend."' Dry/far, "We have said,* that the causes producing chronic diseases'^ Pranged themselves under two general heads ; — those, which act on the nvl'jle body, and which affect the stomach in a secondary way ; — and those, which act directly on the stomach, and affect the whole body through the medium of that organ ; that to these we might add causes, acting upon the whole body and u^- en the stomach at the same time ; such for example as A Rakish Life. A rakish life is too well known to need % description. Tt is often a halo of misery, surrounding the bright* est genius ! To point out its ill effects would be an insult to your understandings. I might as well labour to convince you: of tlie blessings of health or the advantages of industry. I pass * See page 14;- 19 ihe subject over in silence, only remarking in Uie words of Martial, " Balnea, Fina, Vztius* consumunt corpora nostra." Instances of young gentlemen sinking deep into the scartdalous habit of drinking ardent spirits are very rare indeed ; yet it would not be difficult to prove, that there is and has been for se- veral years six limes as mucli ardent spirit expended annually here, as in the days of your grandfathers. Unruly wine and ar- dent spirits have surplanted sober cider.f Is it not the case, that some use them of that strengtli and in that quantity, v/hich is not consistent with the regular functions of the brain ? |. Ma- ny, warmed by the generosity of youth, may think it consonant * Beside the ordinary ronsumption, which is a cougl'mg up of purulent mat" ^r from the lungs "with a Icdlc fe-jer, there is a nervous consumption, a maras- mus, or Tabes dorsalls, of which these are tlie most striking^ symptoms ; — an irksome feeling of the whole body, with an increased sensibility and morose- liess of temper. A painful tenderness of the eyes, with a dminess of sight ; and sometimes a suffusion of tears"; a ringing of the ears ; a disagreeable feel- ing in the skull, as if the membranes of the brain were twisted.* Not only a disinclination to study, hut an inability to concentrate his isleas on any sub- ject. With a failure of digestion, there is a sinking at tlie pit cf the stomach. End a sensation, as if the whole tract of the bowels, with die vesica urinaria, were pulled down, and even scraped. There is a dull pain in the back of the neck, a frigid, disagreeable, shuddering sensation, passing down the back, al- ternating with internal heat, 'fliesc symptoms are more distressing in the morning. The causes continuing-, the function ef digestion is ruined ; a lean- ness and dryness of the body ensue ; the countenance has a peculiar sallow cast, with a physiognomy expressive of unhappiness.

The cellars are ur.occupied, while-, tlie " studies'^ contain the Quas.t-o'j.. \ Of ARDENT SPIRITS and WINE The art of procuring ardent spirits by distiilation wa-v a discovery cf the Arabian chemists. They first obtained it from rice ; whence it took it5> name arrac. At present it is generally procured by the distillation of ferment- ed liquors. In France it is drawn from wines. In England and in Germany from malt liquors ; and in this country and the West India Islands from su- gar and from molasses. This ardent spirit, from whatever subject it is ob- tained, is found, if freed from its phlegm and gross oil, to be essentially the same. By repeated distillatic-ns this sjnrit is puriaad, wiien it obtaies the.. ^s&hic fm&e ef alooM. 20 with prudence to drink so, as to produce tliat exhflaratbn of spirits, which takes place just on this side intoxication ; but I hesitate not to pronounce, that the repetition of such practices i» pernicipus to health and dangerous to morals. Cannot wisdoin Wine is the fermented juice of the grape, and containa three different matters : First a portion of must or unassimilated matter. Second a portio* vi Proper WINE, in which by means of fermentation a quantity of alcohol in produced. Third a portion of Vinegar, produced by too active or too long protracted fermentation. In new wine the must will be most abundant ; a% fermentation advances the portion of genuine •u.'ine will be more considera- ble ; if fermentation has all along been properly managed, 'vinegar will not ap-. pear in any considerable quantity. From the proportion of these several matters, depending on the i)eriod and state of the fermentation, the qiulHie* of wine may be ascertained. See Neumann's C'btm. Lewis' Mater. Mei and Motherby's Diet. The CEnus or wine of the antients ; that, which Paul recommendtn ed, as good for the stomach, was a very different liquor from the wine, drank by the English, Irish, arid Americans. The wine of the antients was th& pure juice of the grape, rendered active by fermentation ; for they were to-. t^'.lly ignorant of ardent spirits ; whereas our strongest wines contain a fourth fart of this fiery spirit, while many of the cheap ones are a vile mixture of eleterious articles, justly ranked among the remote causes of our ner-jous dis- crders, palsies, and apoplexies. If one gallon of our strongest bodied wines ba. tubmitted to distillation, it yields one quart of spirit, that will burn whea thrown on th.: fire. The f;'.'.;ini;iiy of sharp vinegar, contained in the samg^ portion of v/ii.L', jj rot ^so easily ascertained. We will now present you with a few experiments, demonstrating the per- ricious effects of spirituous and vinous liquors, first on the stomach of brutei and next on the human. In Bavaria during the years 1797, 1798, and 1799, the scarcity of foddec compelled them to destroy a great number of horses, employed both for the purjioses of war and of agriculture. Dr. Pilger availed himself of this op- portunity, and made a ninnbcr of cruel experiments on nearly two hundredl horses with arsenic, c; rrosive sublimate, barytes, opium, belladonna, hemlock, laurel water, dlstilh'd spirits, ivine, and vi>"-'gar. After giving horses brandy, so, as not only to exhilarate them but to make them stagger, and e%-en to drop down; he found on opening them, that it shrivelled and contracted the sto- mach, gave a bloodshot appeai-ance to tlie intestines, and produced congestions in the brain. Eat the effect oi 'vinegar was the most remarkable. Concen- trated vinegar excited the most dreadful spasms, and produced fatal symp- toms. They became extrenaely we.ak before death ; and in those, which were killed in this extreme weakness, the alimentary canal exhibited very lit- tle or no irritability on priching its fibre?. That vinegar is destructive to the human stomacli is known by its effects^ on plump, healthy females, who from a silly desire of looking delicate, that i& sickly, swalloVv daily large draughts of vinegar. This innocent practice o«- /v ruins th-edjl<;JsJs to consumption. 2t lievlse a plan of social intercourse-, indcpendtnt of the stirnxiliis of the bottle ? It is said such plans existed in the city of Gex"» VA, before the French inflicted the benefits of ^Zvir] ihert}' on thut philosophic people. From vhat has been said it appears, that some wme makes a twofold ^-i tack on our health and happiness. It i^ttachs the stomacli as v>'ine, and re- turns to the charge in the form of %nne>);ar. Kence in weakly stomachs, wlien the ingcsM aie composed chiefiy of vegetables, and nearly on tlie point of acidity, a single glass of wine, nay half a glass, will turn the whole mass into so much thick vinegar. Then come nagyicslu and i'lme-ivat^r to neutral- ize the vinegar bottle ! Who then but mtjst »ee the absurdity of throwii;g a glass of wine into a nysf-cpiic ftom.ach directly after a dinner, composed chieEy of vegetables ? Yet it" is constantly dpne to the unspeakable distress of the suf- i'erer, agonizing with wind and acid. Physician* ghould endeavour to con- vince such patients, thai v/ind and acid are not the cansea, hut the conse- quences of a torpid, imbecile stomach. They shoakl be told, that when a healthy stomach is moderately filled with vegetables and veil roasted, or ivell' toiled meat, neither air, no? acid is to be found b tlie whole aiiruer.tary canaU Of THS PERNICiODS EFFECTS OF WINE ON CIULDRE?^. The best informed European physicians condemn the practice of glvinsy ■^vine dally to children, k has become a prevalent custom of late in Ameri- ca, to give a glass of wine to such children, as are old enough to sit at taliie with their parents. If the opinion of experienced physicians have no weight with parents, the following v/e!l conceived experiment, being proof pc-itive of the pernicious effects of wine, may possibly induce some to reflect a littlft on the subject. A physician of great eminence in London gave to one of his children a full glass of sheriy every day after dinner for a week. The child was about five years old, and had never been accustomed to wine. To another child, nearly of the same age and under similar circumstances, he gave a lugn Chi- na orange for the same space of fime. At the end of a week he found a ve- ry material difterence in the pulse, the heat of the body, tlae urine, and the stools of the two children. In the first the pulise was quickened, lije heat increased, the urine high coloured, and the stools dutitute of their umal quantify of bil.' \ while the second had every appearance, tiiat indicated high health. He then reversed tfje experiment ; to the frst meiitioned child he ga-vre the orange, and to the other the wine. The effects followed as before ; — ^ siril-. ing and demonstraii'ue ^raofnf the pernhioHS ejfects of ivine on the cotutitution of cbtl-. drcn in full hsaith. I'his accurately e:tecutQd experim.ent is related by Tvlr. Sanford, Surgeon at Worcester in England, and quoted by Dr. Beddoes in his Hygeiei ; v;ho thus remarks on it, " that the difciency of bile is full evidence of the injurious ef- " feet of v/ine upon the digestive organs in this double experiment.'" Yet. "we find that some physicians have leainied their patients to attribute these ve- ry complaints to a redundancy cf bile ! and therefore prescribe salt of ivormiLor.i and rhuhr.rb ; or soap, rhiibirb, aud aloes, inducing thereby a farther weakness of the digestive organs, tlie proximate cause cf the disorder. IVIy venerable pre- ceptor, Dr. FoTUEaoiLL cured such ccmplaints with fresh made pnrt.r. Ey the time London porter arrives in tliis country it contains too much vii:egar to be serviceable in these cases. Alahomet with a view to temperance forbad his follovi-ers to drink wine j. and in order to correct their savage -custom of eating raw flesh, as do ti'.o^ Among the causes, wliich act directly and immediately oa, the stomach, wc mentioned, besides ardent and vinous spirits, ccr* tniu Narcotic substances. Narcotics are soporiferous drugs, "which induce stupefac- tion. It is the property of narcotics to exhilarate first, and tlien to relax and stupify. They invariably debilitate the organs, to ^vhich tliey "Arc immcdtatcly applied j at lengtli they have a simi- lar effect pn the; whole system. At the head of this class of drugs we place opium,* which is the milky juice that exudes fiom the heads of poppies, wlicn incisions are made in tl:iem j .;ind then gradually dried in the sun. To this class belong alsa Cicuta or hemlock, Belladonna or deadly nightshade, Stramonium ©r apple of Peru, and Nicotiana or Tobacco.. The Turks, who were forbidden by Mahomet to drink wine, intoxicate themselves with opium. It is said, that some will cat more than an ounce in a day. We have seen, that nothing «o efFectually preserves health and prevents disease, as maintain-, ing the tone and regular motions of the digestive organs ; and 'there is no drug in common use, which renders them so tor- pid, and which so effectually stagnates their functions as opium. cAfter destroying the eneigy of the stomach, it undermines the powers of all the othci organs in succession, even to the orgaa ,of thoBghu Travellers inform us, that the visage and general ap-^ pearance of the opium-eaters in Turkey are the most disgusting imaginable ; even worse than our most abandoned rum-drinkers.. •Some of these miserable Turks have however mind enough left: lAbyssinlans at this clay, he allowed them to eat any thing, that h,TijA passed ■through fie ; nicaninp whatever had undergone the ]>rocess of cookery. A century or two after his death, the chemists of liis country discovered the art lof drawing ardent spirits from rice by distillation. When tliese mahonietan* .■were reproached for intoxicating themselves with this spirit, which they called mrracy they replied, that // hud passed through fire, and was therefore agreeable to the laws of Mahomet, as expressed in the Koran. * (J A I. EN was the first of the Greek writers, who mentions opium. It wat Init little used anionp the antients. PamrtUvs and Sllvius de la B»'n brought it, ipt« vogue ki Eurv?b destroy themselves by the dagger, to prevent living or ratlicr hreathltig a few years longer in a state of confirmed idiotism, which is the fate of most of them during tlie latter years of their exist- ence. Thus much for opium : but what shall we say of M- cetiana* or our beloved Tobacco ? With wliat caution should a man proceed In attacking a £».- rourite of the people ? A prudent man, one who wishes to sail quietly down the popular stream, would be disposed rather to flatter and applaud the object of their affections. But an hon- est man, who differs a little from him, commonly designated as « prudent one, can never flatter, where he feels a friendship. He wilj, give die true character of a dangerous inm.ate, and warn his friend of the consequences of cherishing a viper In his bosom. Yon already perceive, that although we would give *' fair play" «ven to a treacherous enemy, yet Tobacco has done and is secret- ly doing too much mischief to expect any more from us, than a jevere trial and rigorous justice. The great Linn^us has beside his celebrated ari'ijic'ial classi- fication given us a natural one. In his natural arrangement he has placed Tobacco In the class Lur'id^ ; which signifies pale, gastly, livid, dismal, and fatal. To the same ominous class be- * NicoTiANA, SO called from "Jjcolms Nicotim, ambassador to the court of Portugal from Francis II. king of France. Nicoilus bought some seeds of this plant from a Dutchman in 1560, who had just brought them from Ame- rica. From this seed the plant was produced in France. Sir Francis Druie carried it to England ; and Sir IValhr Jialcigh first brought it into fashion. The dried plant was afterwards imported in great plenty from Tobago, and hence it obtained the name of Tubacco. Linnjcus places this genus of vegetables in the first section of his fifth class, which contains those plants, whose flowers have five stamina and one style, which expressed in botanical language is Pentandria, Monogynia, 1'his genus has eleven species ; one of which is called Hyoscyawus from its agreeing in several of its characters with the deleterious henbane. Nicholas Monardus a German has written a folio on the virtues of tobacco. It is doubtless a valuable medicine, especially in cases where the Digiijlis has been used without success. An English physician, Dr. Fowler, used a tinc- ture of tobacco in 52 cases of dropsy, and found it efficacious in 49 of tliem, The same physician found it very beneficial in Dysuria- from gravci ^ k«ve u«cd it in sucfi casoR witli sati^fRctiot. ^4 Jong Foxglove, Henbane, Deadly-nightsliaJc, and another poi* sonous plant, bearing the tremendous name of Atropa, one of the Furies, Let us examine one of them, viz. Tobacco, its qualities* and its efFects on the human constitution. VvHien Tobacco is for the first time taken hito the mouth, \t creates nausea and extreme disgust. If swallowed it excites vio* lent convulsions of the stomach and of the bowels, to eject the poison either upward or downward. If it be not very speedil/ and entirely ejected, it produces great anxiety, vertigo, faint* Hess, and prostration of all the senses ; and in many instances death has followed* The oil of this plant is one of tlie strong- est of vegetable poisons, insomuch that we know of no anin^al, that can resist its mortal eifects* These are, without exaggera- tion, some of the lurid qualities of our beloved tobacco. Let ui now see, if it can be agreeable to the laws of the animal oecono-i my, or consonant to common sense, that a plant witli such quali-* ties can act otherwise than detrirasntal to the tender constitutions of young persons. Tlie human organs are endowed v/ith a faculty of selecting certain wholesome articles, and our digestive apparatus of assimi- lating and changing them into our own nature and substance. Beside this nutritive faculty our organs are endowed with a re* pulsive one, with certain instincts or perceptions, by which they reject whatever is unwholsome or pernicious to our well being* These powers and faculties, purely instinctive, are more or less possessed by every healthy animal. Man endued witli rea^oa has these instincts in less perfection, than the brutes. The organs of the senses are so many guards or centlnels, placed at those avenues, v\'liere deatli is most likely to enter. For illustration let us suppose a man cast ashore on some uninhabit- ed island, and roaming among unknown fruits and herbs with a desire to satisfy his hunger ; he knows not whether, what h? 25 finds be wholesome or poisonous. What naturally follows ? The first examination, which the vegetable undergoes, is tliat of die iye ; if it incur its displeasure by looking disagreeable and for- bidding, even this may induce him to throw it away ; but if it be agreeable to the sense of seeing, it is next submitted to the Examination of the smell, which not unfrequently discovers latent mischief concealed fVom the sight ; if not displeasing to the siglitj nor disagreeable to the smell) he readily submits It to the scruti- ny of the next guard, the tongue ; and if the taste too approbate the choice, he no longer hesitates, but eating it, conveys it Into his stomach and intestines ; botli of which, like faithful body guards are endowed with a nice perception and prompt action, by which, if what was eaten as wholesome food, should notwith- standing all the former examinations still possess a latent quali- ty, injurious to life, the stomach is stimulated to reject it upward, or tlie intestines to expel it downwards. These internal percep- tions and consequent exertions are the first and most simple acts of nature, being purely Instinctive, constituting what physicians call the " Vis medlcatrlx natuvit" or reaction of the system.* Let us suppose, that oiir hungry adventurer had fallen on the tobacco plant ; he would find nothing forbidding in its ap-* pearance ; to his smell It •would be rather ungrateful ; to his taste so nauseating, that it is surprizing, how the same man evei^ ventured to taste green tobacco twice ; but if taken into his sto- inach, convulsions, fainting, and a tempoiary loss of his senses follow ; accompanied with violent and nasty operations. If that, Which is wholesome, affect the senses of animals with pleasure, and invite therfi to convert it into their own juices ; and if tliat, which is unwholesome, excite disgust in smell, taste, and apj^c- tite, then would Our adventurer rank this herb among poisons, and note it as one of those, which nature forbade him to use. Yet man by perverting his nature has learnt to love it ! anil * 666 Mr. Mudge's essay on the Vis VlUt, D 2S "uheh perverted nature excites a desire, that appetitfe or desire li juiordinate and ungovernable ; for the reaction or physical resist^ lince tu evil will, like dial of the moral, lessen in propor|:ion to the repetition of the attacks ; and then those guards of health,} already mentioned, deseit nature^ a,nd go over to the side of her. enemy } and thus we see how intemperate drinking and immo- derate smoking began their destructive career. The f.rst effect of tobacco on those, who have surmounted the natural abhorrence of it ; and who have not only learnt' tO endure it, but even to love it ; and who have already commenced the nasty custom of chewing or smoking, is either a waste or vJ-J tiation of the saliva. The saliva or spittle is secreted by a complex glandular ap^ paratus from the most refined arterial blood, and constant- ly distils into the mouth in health ; and from the mouth into the stomach at the rate of twelve ounces a day.* It very much re- sembles the gastric juice in the stomach ; and its importance in digestion may be imagined after listening to the words of the great Boerhaave.
