dance, &c. The spinal marrow in such cases often exhibits a 
rosy red colour, with some dusky spots and streaks, enlargement 
of the minute vessels, injection of its membranes, oftentimes dis- 
tinct swellings, and always more or less variation from its usual 
consistence; namely, hardening, or more commonly softening, or 
complete dissolution into a discoloured fluid, frequently mingled 
with blood. More rarely does the inflammation of the spinal 
marrow appear to run into true suppuration n ; small abscesses 
even have been found in it 12 . Still more unfrequently does gan- 
grenous destruction occur in the spinal marrow ; never indeed 
primarily, but only in defined spots. Spurious formations 
in the spinal marrow are uncommon, viz. tumours, tubercles, and 
sercoms 13 . In a few instances only have extraneous bodies 
been observed to remain in this organ u .

To a lecturer this work is beyond all price: it should be at 
the right hand of every medical writer ; and the student will de- 
rive from it enlarged and correct views of the pathology of every 
part of the frame. The notes of M. Otto display most extensive 
research, and the translator has added many which do credit to 
his talent and diligence. 
No work, however, is perfect ; and we must expect some trifling 
errors, and especially when the writer is compelled to speak of 
that which could not have come under his own personal observa- 
tion, and for an account of which he was compelled to rely on 
very insufficient sources of intelligence. 
We smile when our author tells us, that “ sandcrack usually 
arises mechanically from false quittor, whereby the hoof is entirely 
thrown off at the coronet ;” although we agree with him, in tfie 
same section, that (t the hoof of the horse, in corns, is sometimes 
softened, loosened, and soaked in blood;” and that “ to ab- 
scesses of the nails belong the quittor and thrush of veterinary 
physicians.” We wonder a little when gravely informed that the 
wolves’ teeth in the horse grow in the palate ; and we must cer- 
tainly enter our protest when we are gravely told that windgalls are 
“ tumours full of synovia, which originate in a partial extension 
of the articular capsule.” But these are trifles light as air com- 
pared with the sterling value of the work. He has given a suf- 
ficient reason why these defects must occur : — “ anatomists and 
pathologists rarely possess sufficient zoological and zoomedical 
knowledge; while veterinary physicians, on the other hand, have 
as rarely sufficient knowledge of physiology and pathology.” We
