are to pursue, and both founded not on theory, too often decep¬ 
tive and worthless, but on repeated experiment. 
Next comes a very unobtrusive but valuable description of 
that malady, almost uniformly fatal, “ Bronchitis in Cattle.’’ 
The symptoms are well and accurately sketched. The disease 
can now be scarcely mistaken, and the practitioner will not 
blunder and lose time by having recourse to inefficient measures. 
The operation of tracheotomy will not be neglected in urgent 
cases ; and, perhaps, to inhalation of the vapour of turpentine 
will be added the administration internally, and in no small doses, 
of a medicine that so soon enters into and pervades the whole 
circulation. 
The concluding portion of M. Hamont’s Essay on the Rot in 
Sheep will be read with feelings of a mingled character. The 
facts which he states of the sheep of the Egyptians and the 
Bedouins being equally attacked by this disease when they feed 
on the pastures from which the waters of the Nile have just re¬ 
ceded—and the opposite termination of the disease in the flocks 
of the one and the other—and the means by which the sheep 
of the Bedouins are rescued from the impending fatality, while 
so great a portion of those of the fellahs are destroyed,—are 
exceedingly interesting, and will give rise to much serious and 
useful reflection. 
The theory of M. Hamont will likewise receive due consider¬ 
ation, although, perhaps, we shall doubt much whether this 
feeding on the dyssa, saturated with the watery principle, and 
producing an entire decomposition of the blood, is the true expla¬ 
nation of the disease ; or rather we shall wonder that, tracing this 
disease to the banks of the Nile alone, and appearing there at one 
season of the year only, namely, a little while after the waters 
had retreated to their proper channel, and had left a surface rich in 
vegetation, exposed to the influence of a burning sun, and conse¬ 
quently decomposition rapidly taking place, he had not attributed it 
to the baneful influence of the effluvia or emanations which must 
then be emitted ; and especially when a similar disease, almost 
identical in its symptoms, progress, and termination, attacks, at 
the same time, the human being who is exposed to the same 
emanations, but does not live on the same food. 
Our surprise may, perhaps, be a little increased, when we find 
M. Hamont (p. 540 in our last number) giving credence to an 
assertion of M. Gasparin, with regard to the proportionally small 
quantity of blood which flows in the veins of the sheep, and 
making it the foundation of certain reasoning ; whereas, instead 
of the sheep having little blood compared with the ox, he has, 
in proportion to his size, and as we should expect from the nu-
