This will certainly stimulate the courage of many workers, 
and the bacillus of Koch will -have to look out very close 
if it' wishes to escape the enormous army of searchers 
and bacteriologists which all over the world will conspire 
against it.

Serotheraphy is the method of treatment which borrows 
its agents and therapeutic means from natural or artificial 
serums : natural , such as that of the physiological blood, that 
of the blood from cured or convalescent individuals, that of im¬ 
munized anima.]^ ; artificial , although this expression is scarcely 
properly applied, for saline solutions which do not resemble, 
even roughly, the complex composition of the serum of the 
blood. But debatable as it may be, it is admitted, and will 
probably stay in ordinary nomenclature. 
Of the natural serums used in veterinary practice, but little 
can be said, as, perhaps, with the exception of the antitetanic 
serum, which is considered essentially as a preventive, they 
have found but little application in veterinary medicine. It is 
true, however, that the antistreptococcic serum of Maroneck has 
been used with more or less satisfaction ; perhaps, also, that of 
Calmettes, and I believe also attempts have been made with the 
antidiphtheric serum. The typical among the artificial serum is 
the secretion of chloride of sodium (ordinary salt), although 
there are others made of various saline solutions, but which 
have somewhat the same essential properties. The medicated 
serums are simple serums to which various drugs have been 
added. 
The type of the artificial serum, the solution of common 
salt, so-called physiological, is quite extensively used in human 
medicine, and the benefits which have and are obtained by its 
use are matters of record in many medical journals in Europe. 
In a previous article we have already briefly alluded to the sub¬
