that the demonstration of any one of the aboved-named eight pro¬ 
minent features of this affection forbids absolutely the idea that 
it is foot and mouth disease. How much more, then, is that mal¬ 
ady excluded under the combined antagonism of all these eight 
counts.

Tuberculosis inoculated, through the eye. —We have here a mode 
of demonstration which is placed beyond question, inasmuch as it 
permits us to follow step by step all the phenomena of the con¬ 
tact of the tuberculous bacillus upon the various tissues of the 
eye. 
It is Cohnheim who originated the ingenious idea of introduc¬ 
ing the tuberculous matter into the anterior chamber of the eye. 
The recent experiments of Baumgarten, published as “ The De¬ 
monstration of the Pathogenic Value of Tuberculous Bacilli by 
Histology ,” leave no room for doubt as to the insertion of the 
virus and the gradual development of the bacilli in the media of 
the eye. The tuberculo-bacillar substance being introduced into 
the anterior chamber of the organ for the first four days, no al¬ 
teration is observed, the tissues of the eye appearing unchanged, 
yet every day the bacilli are visibly developing themselves in 
statu. Towards the fifth day they are observed to be extending 
and increasing in number, and outside of the tuberculous frag¬ 
ment, to occupy the cornea and the iris, and it is in the parts 
where they most abound in number, and all around them, that 
new so-called epitheloid cells are found. These appear first in 
small numbers, then increasing, and again, still more numerously, 
until the tuberculous nodule is found, the size of the tubercle 
and the abundance of the epitheloid cells always corresponding 
to the numbers of the bicilli. 
Facts occurring in a similiar order are observed in the kidneys
