extends to the larynx and pharynx. The alteration of the voice 
clearly indicates this; but whether it extends to the lungs and air- 
tubes has not been ascertained. Pneumonia, or inflammation of the 
substance of the lungs, with the exception of the formation of tuber¬

toma lineare.

gallinacse, are manifold, but of little interest to the veterinary

The present little work forms a sort of sequel, or second volume, 
to one of a similar nature which came under our notice so lately as 
November last: the former was directed principally to the consi¬ 
deration of the economy of the stable, and the management of the 
horse therein; the present is intended to direct our steps in that 
hazardous investigation — u the search of a horseand reckoning 
the many we have already on the subject, it might, with a great 
deal of reason, be said, “ of such a work there is no need.” Our 
author, however, has answered, or rather has forestalled, this re¬ 
mark, by informing us that he has not pursued the beaten path of
