REVIEW — PERCLVALL ON GLANDERS.

before a good constitution liberally sustained ; we see the other 
invariably cutting down the stoutest and most robust, though backed 
up by every advantage that medicine and diet can afford. The 
same causes produce both ; they are convertible one into the 
other; the one too frequently terminates in the other: true. This, 
however, does not prove them to be one and indivisible ; nor, 
while cases are to be met with in which farcy is existing that 
might have been cured, but that glanders has been caused to super- 
vene by inoculation, the two diseases running their course together, 
shall we become sincere converts to the doctrine. We have also 
much greater faith in the permanency of the cure of farcy than 
our talented author appears to entertain. We have carefully 
watched animals for years after severe attacks of farcy have been 
eradicated from their systems, and they have died commonplace 
and usual deaths, without any re-appearance of the disease; how- 
ever strong the evidence may be, therefore, of the identity of farcy 
and glanders, it is not complete, and therefore does not command 
our belief in its infallibility. 
We have often endeavoured to ascertain the relative proportion of 
cases in which the lungs have become affected and are the cause of 
death in glanders, but we have been unable to do so. Mr. Percivall 
informs us, that in those instances where the acute supervenes upon 
the subacute and chronic species, death is the result of phthisis pul- 
monalis; and we quite coincide with his opinion, and are disposed to 
believe that, classing the entire number of deaths into those depend- 
ing on disease in the lungs and those not, the relative proportion of 
the former will be found to be much larger than is generally ima- 
gined. In using the term phthisis pulmonalis, however, we must 
give the qualification insisted on by our author. “ For my own part, 
I feel disposed to think that the production which is taken for and 
called a pulmonary tubercle in glanders or farcy, but which may 
turn out to be nothing but a portion of diseased lymphatic, must be 
a different thing from veritable tubercle of the lung.” — “ This fact 
may not of itself be sufficient to prove one so-called tubercle in 
the lungs to be different from another : weighed, however, with 
what has been before advanced, we think it strengthens our opinion, 
that the pulmonary tubercle of glanders, and that of pneumonia or 
phthisis, are substantially different productions.” 
We have often mused, — we cannot say thought, for thinking is 
by far too great an exertion to be often had recourse to, — on the 
predilection of glanders for the near side of the body, not of the 
head alone, but the chest also. White fully bears out Dupuy’s 
observation on this point ; and without, however, be it understood, 
meaning to give an opinion on the matter, we have occasionally 
fancied that farcy also has a similar preference for the left : as to
