curs oftenest in equidae, while osteomalacia is principally 
met in bovidm ; the former is a disease of middle life irre¬ 
spective of sex, and the latter is an affection of the pregnant 
period. Different locations of the same process should never 
constitute separate diseases ; but rather different processes, 
whether they occur upon the same region or are widely 
separated one from the other. 
THE NEW PHTHISIS REMEDY. 
By the Same. 
Before the tuberculin of Koch has been sufficiently inves¬ 
tigated either clinically, pharmacologically or chemically, 
there has already appeared another anti-tubercular remedy, 
which is concentrating professional attention upon itself. It 
is the universally known cantharides which is now recom¬ 
mended, and with which we are better acquainted than the 
human physician. Cantharides contains, among other constit¬ 
uents, an aromatic, irritative substance named cantharidin. 
This active principle, when brought in local contact with 
the skin, mucous or serous surfaces, especially in the kidneys, 
causes a seious transudation. Liebreich has demonstrated 
that this infiltration also occurs in the lungs, and that in this 
locality it is independent of the blood pressure and directly 
relative to the influence of the cantharidin upon the walls of 
the capillai ies. He further states that this transudation occurs 
to a moie considerable degree in altered or diseased organs, 
than in those acting physiologically. Through increased quan¬ 
tity of serum, there should result an invigorating and more 
complete nourishing of the part, and therewith, contempora¬ 
neously, an increased power to withstand the bacillus. 
As proof of this, Liebreich adduces the fatal working of 
simple blood serum upon the bacillus as found in canidas and 
leporidas. 
This new method has been named by the discoverer “ the 
serum therapy.” *
