establish the fact, contradicted by the assertions of a physiologist 
at Nancy, that the dissolvent properties of this juice are caused by 
an organic acid, analogous to lactic acid, united with a very small 
quantity of chlorhydric acid. The researches of Messrs. Tiedmann, 
Gmelin, Chevreul, and Leuret, had before demonstrated this most 
clearly. 
M. Clement, chef de service , attached to the chemical and phar- 
macial department, has chemically analysed a quack medicine 
puffed up by some empirics as an infallible cure for the diseases 
of young dogs ; and has discovered that this medicine, the effect of 
which is doubtful, consists of seven parts of coarsely powdered 
sulphur and three parts of coloured vegetable powder slightly 
sapid — added, doubtless, in order to conceal the yellow hue of the 
sulphur. 
Chair of Pathology and Therapeutics. 
Professor M. Delafond. 
This Professor has been continuing the experiments that he 
commenced last year on the action of medicines on different domes- 
tic animals. The results which he has thus obtained have been 
stated in the second part of the “ Traitede Therapeutique ‘generate, ” 
which he has published. 
For some time past this Professor has employed himself in 
studying a very serious disease among cattle, known under the 
name of peripneumonia. As veterinary surgeons are by no means 
agreed respecting the nature and contagiousness of this disease, he 
has resolved to publish the results of his researches in a “ Treatise 
on Peripneumonia,” which is nearly finished. For almost four 
years he has, conjointly with Dr. Gruby, undertaken a series of 
researches : — first, into the organization of the intestinal mucus of 
various domesticated animals, the morbid phenomena of which it is 
the seat, and the important functions which it fulfils in the act of 
digestion; second, the composition of the gastric juice — the diges- 
tion of animal and vegetable substances — absorption — the com- 
position of chyle — its mixture with the blood — and the organic 
nature of lymph and its mixture with the blood. 
These researches have led the two experimenters to the obtain- 
ment of some very interesting results, which it is their intention 
shortly to lay before the public. We subjoin a succinct sketch of 
some of these results : — In herbivorous animals a very great quan- 
tity of animalculi of various kinds are developed in the first stomachs 
of ruminants and the large intestines of horses. These, after hav-
