the cutaneous sensibility of the hind limbs. The history of 
the animal is also important in determining the cause. 
Before closing this paper I wish to enlist the services of 
the members of this Association in obtaining further material 
for finishing a work that appears at present promising. I will 
take it upon myself to examine any material sent to Clark 
University, Worcester, Mass., and report the results of the 
examination to the person who sends it. The cord after being 
taken out (and the whole cord is desired) should be placed in 
a 2-5 per cent, solution of bichromate of potash plus one-sixth 
its volume of 95 per cent, alcohol, and expressed to the above 
address.

These inconsistencies show that the whole argument lacks 
candor or even a desire to reach the truth. It may be freely 
admitted with Frosch, and as we have shown in our reports, 
that this germ, in common with many others, varies greatly 
even in its staining properties when obtained from different 
outbreaks, or when grown under different conditions. The 
same is true of the swine-plague germ. This, however, does 
not prevent each from having its peculiar staining, which is 
valuable as a diagnostic point when taken in connection with 
other morphological and biological characters, but which 
alone is not sufficient to determine a species. 
That the figures of the hog-cholera germ in our reports 
do vary somewhat as to the staining, as charged by Frosch, 
is not denied, but he surely is the last one to consider this as 
bearing against the value of our statements, for he expressly 
calls attention to the variations which are liable to occur and 
to the delicacv of the manipulations necessary to get com¬ 
parative results. Our figures were drawn from the natural 
objects and were correctly drawn, if they had been diagra-
