REVIEW OF MOIROUd’s 
Tamarinds. —The pulp of this fruit acts on the animal eco¬ 
nomy much like that of cassia, but is more cooling and refresh¬ 
ing : it is indicated in all acute inflammations, but is seldom used 
on account of its price. 
Castor Oil. —This is a very mild purgative, and is indicated 
in all those cases in which it is expedient to evacuate the bowels 
without irritating the primae vise. We have given it with suc¬ 
cess in stomach-staggers in the horse, and in stercoral colic : it 
is given to the dog in obstinate constipation, to which that ani¬ 
mal is more subject than the herbivora. The dose is one pound 
for large animals, and two or three ounces for the small ones. 
It should be beaten up with thick mucilage, honey, or the yolk 
of an egg. It is given with benefit in cases of worms, not only 
on account of its poisonous action on them, but as promoting 
their expulsion like other purgatives. The seeds are sometimes 
given to pigs and to dogs as a purgative, to the number of four, 
six, eight, or ten, bruised, and in a small quantity of aliment. 
Second Class of Special Excitants, 
MEDICINES WHICH ACT PARTICULARLY ON THE STOMACH, TENDING TO 
EXCITE ANTIPEftlSTALTIC MOTIONS, AND THE REJECTION OF ITS 
CONTENTS. 
Emetics. 
We shall not describe the series of phenomena which precede, 
accompany, and follow vomiting; nor search into the circum¬ 
stances which oppose that operation in the solipede and the ru¬ 
minant : it will be sufficient for us to observe, that among these 
animals emetics do not ordinarily produce even nausea; and that 
the return by the mouth or the nostrils of substances contained 
in the stomach (the fourth stomach) is always a pathological fact 
of a very serious character. We are deprived, as it regards them, 
of a resource by means of which we are enabled to accomplish 
many important indications in the medical treatment of carni¬ 
vorous animals. Emetics are often employed as simple evacu- 
ants ; in recent cases of poisoning, in indigestion, and in bilious 
affections, we have recourse to them to produce a sort of revul¬ 
sion to the intestines, or the secretory organs, or the skin; and 
also in bronchial catarrh, in the distemper of dogs, and in some ex¬ 
anthematous affections; and we endeavour to make use of the ge¬ 
neral disturbance which they cause in the constitution, in cases 
of asphyxia, syncope, and certain morbid conditions, the charac¬ 
ters of which are obscure. The practitioner is thus sometimes 
enabled to impress a pathological character, and a determined 
physiognomy on the disease that he has to combat, as well as a 
regular succession of symptoms.
