not affect them in the least. The compact nature of these bodies 
was further demonstrated by the fact, that, on pressing together 
the two glasses between which the substance was interposed for 
examination, the masses split up in a regular manner from the 
centre to the circumference. 
This very strange deceptive appearance bearing such a close 
resemblance to common fat, was detected by Dr. Jenner, Pro¬ 
fessor of pathological anatomy at University College, who 
kindly aided me in examining these interesting morbid products. 
It is not to be wondered at that the microscopic characters of 
oleine are deceptive, when we reflect on the fact, that they 
depend on the peculiar manner in which this substance re¬ 
fracts light. 
Proceeding with the examination of the substance, it was 
found to contain granular matter, which dissolved with effer¬ 
vescence in hydrochloric acid, owing probably to the existence 
of a carbonate, perhaps of lime. Nitric acid had more or less 
the same effect. On the addition of ether to a portion of the 
substance after its earthy matter had been destroyed by hydro¬ 
chloric acid, the crystals of cholesterine and fatty granules were 
dissolved. As the ether evaporated the fat was deposited, 
modified in character, and interspersed were crystals, as seen in 
the annexed Figure 2.

Besides these were clusters of organic cells, consisting of an 
envelope with an apparently vesicular nucleus, containing gra¬ 
nular matter, and one or more nucleoli. See Fig. 3.
