ard points out the mischief which has been occasioned in a 
flock by inoculation for sheep-pox. He speaks of those gangren- 
ous tumours which used to be so often met with, and which 
were generally supposed to be caused by the punctures having 
been made too deep : it appears, however, to be his opinion, that 
the warm moist state of the atmosphere had most to do with 
their production in the cases which he is narrating, the animals 
having been inoculated about the latter end of August. The 
other relates to the transmission of sheep-pox to the foetus, by 
the inoculation of the mother during the latter part of the term of 
gestation. M. Drouard believes in the possibility of this trans- 
mission, and recites two cases which, it appears, came under his 
personal notice, and which are quite sufficient to dissipate all 
doubts on the subject. 
The following is one of these cases : eighty ewes with young 
were inoculated in December, sixty-eight of which took the 
sheep-pox. After the lambing season, all the lambs were inocu- 
lated. Two shewed symptoms of the disease, and these were 
recognized by the shepherd as being the offspring of two ewes 
on whom the inoculation took no effect. 
The next paper is upon the use of the leaves and stubble of buck- 
wheat, and the disorders occasioned by it in sheep. 
The disorder here alluded to broke out suddenly among a 
flock that was grazing on a piece of ground that had borne a 
crop of buck-wheat (polygonum fa gopy rum), and attacked about 
one-third of them. The prevailing symptoms were incessant 
restlessness and impatience, which caused the animals to run 
their heads against every surrounding object, and to rub their noses 
either against these objects or the ground, or against their fore 
legs. The whole of the head swelled to such a degree as to 
cause absolute deformity ; but, subsequently, all these symptoms 
disappeared as suddenly as they had arisen. 
M. Drouard is led to attribute this affection to the stubble of 
the buck-wheat, from the circumstance that of the three flocks 
which were pastured on the piece of land in question, the dis- 
order broke out in but one, and that was composed of ewes that 
had been fed on wheat-straw and the stubble of buck-wheat for 
five weeks before they were turned into this ground, and thus 
had become predisposed to take on the disease, which the other 
flocks were not. 
Under the title of unnatural parturition , we find four cases 
highly interesting, as well from the seriousness of the complica- 
tions which presented themselves, as from the nature of the means 
which were had recourse to in order to accomplish the birth. In 
three cases M. Drouard found himself compelled to have recourse 
to embryotomy, and the foetuses were extricated from the womb
