great weakness, which, however, gradually disappeared, and on 
the sixth day afterwards he appeared to be perfectly well. 
Three other horses were afterwards cured by the same means; 
and after this a fanner, who had lost four under the use of bleed¬ 
ing, antimony, and setons,* in this affection, consulted Mr. 
Manginfortwo others, which were cured by purgatives. 
Mr. Mangin attributes the disease to the hay made in the 
year 1816, in a very rainy season; and in some other cases, in 
the next year, to the use of green trefoil, as the sole food. 
Some other horses affected with it had eaten copiously of new 
oats. 
Professors Burdin and Dupuy blame Mr. Mangin for having 
administered so large a quantity of aloes in so short a period; 
but Mr. Mangin apologizes for his practice (which would ex¬ 
cite excessive purging in a healthy horse), by obseiwing, that the 
horse is here in a comatose state; in consequence of which, 
purgative medicines do not act with their ordinary energy. 
EX^TRAORDINARY SALIVATION FROM FEEDING 
ON THE CHARLOCK, OR WILD MUSTARD. . 
A HORSE, after a long abstinence, during some moderate 
work, ate, with much voracity, a large quantity of herbage, 
composed, partly, of the plant sinapis arvensis, and afterwards 
voided, in the space of tw^elve hours, nearly six pailfuls of sa¬ 
liva. Three cows, who also ate of this plant, manifested si¬ 
milar effects, though to less extent. Two asses,- for the sake 
of the experiment, were forced, by privation of other food, to 
eat of this vegetable; but they presented no such effects : the 
quantity of it eaten by them was, how^ever, very small. — Compte

Mr. BOULEY, a very able veterinaiy surgeon .of Paris, 
bled a horse, having pneumonia, in the neck, with the phleam, 
in the usual way. Nothing particular occurred during the early 
part of the operation; but, as the vessel into whiclfthe blood
