fluids after standing for some time, separated into two parts 
—a curdy deposit and an amber-coloured whe}'’. The same 
elements were found in both constituents;—viz., large gra¬ 
nular masses of a brownish-yellow colour, numerous pus-like 
bodies, bacteria, vibriones, moving spherical bodies, and a few 
milk-corpuscles. 
It is particularly worthy of remark that these morbid 
elements were found in specimens of milk which in their phy¬

In some specimens which were viewed with the micrometer 
eye-piece the milk-corpuscles varied in size from 1-2000th to

affected with cattle plague and also with pleuro-pneumonia

plague similar elements were distinguished in the curdy
