REVIEW OF MOIROUD.

Even with those that do seem to undero;o the disorder, local 
abscess does not invariably occur; nor, indeed, do I consider it 
essential to answer the ends of nature. P.

Vetermaire: par M. Moiroud. Paris, 1831. 
(Continued from p. 236, vol. v.) 
We shall occasionally resume our review, or rather analysis 
of tiiis work, if it is only to put our readers in possession of the 
opinion of our continental brethren respecting the medical pro¬ 
perties and effects of the different articles of the veterinary phar¬ 
macopeia. 
Laxatives. 
Manna. —The purest manna may be given as an article of 
food, and then, being perfectly dissolved in the stomach, it has 
no purgative effect; but the coarser species of manna resist the 
power of the stomach, and thus pass into the intestines without 
having been decomposed: the intestines, irritated by the pre¬ 
sence of the drug, increase their peristaltic motion in order to 
expel it the more quickly, and with it, and after it, they expel a 
part of the stercoral matter which they contain. Manna is, 
therefore, used in inflammatory complaints, the resolution of 
which we usually endeavour to effect by evacuants : we, how¬ 
ever, give it only to the small quadrupeds, because it would 
require too expensive a dose for the larger ones. Some have 
recommended it in small doses, in chronic pulmonary catarrh. 
We have tried it in the horsedn doses of two ounces, incorporated 
with honey, and continued it during fifteen or twenty days, but 
without any good effect. 
It is given to the carnivora in doses of about two ounces dis¬ 
solved in water, broth, or milk; but I think that a smaller dose 
repeated daily is more beneficial in chronic bronchial catarrh, 
and especially in that which accompanies the distemper in dogs. 
Cassia. —This is a mild laxative, very useful in most visceral 
inflammations, and principally that of the liver; but the use of 
which is limited by its great price, compared with the quantity 
necessary to be given.
