dull milky tinge; not the appearance presented after death, but more 
opaque. It is difficult to describe the difference, but it will be immediately 
appreciated when seen. Second, after two hours, or thereabouts, some one 
point near the centre of the cornea becomes obviously whiter and more 
opaque than the remainder, and looks rougher and more granular ; in fact, 
looks like a recent ulcer in the first stage. Third, during the course of six 
or eight hours the cornea becomes quite opaque, so that no portion of the 
pupil or iris can be seen ; the epithetial layer peels off in large pieces with 
great ease ; the whole globe becomes flaccid; the sclerotic much softened ; 
the crystalline is slightly less transparent in sheeps’ and pigs’ eyes, but 
small eyes may be semi-opaque ; the aqueous humour is turbid; the vitreous 
reddened but transparent; the retina, except round the optic nerve, con- 
verted into dirty-looking pus, mixed with the débris of the pigment layer of 
the choroid. The recti and other muscles are pale ; the cut extremity of the 
optic is reddened. When portions of the epithetial layer of the cornea are 
detached, they appear the colour of whitey-brown paper when wetted, but 
are more opaque. Under the microscope, to quote from the notes, “The 
shreds of fibrinous exudation in the anterior chamber are composed of 
granular masses faintly marked out into cell-like portions. The epithetial 
layer of the cornea is a mass of proliferating cells, the nuclei of the flat 
epithetial being much enlarged and quite round; immense numbers of 
cells, four or five times the size of a human red corpuscle, and exactly 
resembling these enlarged nuclei, were floating about in the immediate 
neighbourhood of these shreds of epithetium. The columnar and spherical 
cells were all enlarged, and in many the nucleus was showing a tendency to 
divide.” The deeper layers of the cornea are full of young cells, and the 
normal structure is often quite obstructed by their number. In addition to 
the shreds of fibrinous exudation in the aqueous, “it contains numbers of 
detached leucocytes.”’ 
* The crystalline shows, without any staining or preparation, its fibrous 
structure; the nuclei of the fibres are much enlarged and very distinct. 
When the crystalline is detached from the eye and immersed directly in 
blood it assumes a sort of opalescent tint. 
The smaller vessels of the choroid have disappeared, the pigment cells 
are almost all broken up, and in the most advanced stages nothing but 
pigment granules can be seen. 
The retina, except just round the optic, is, as has been said, dissolved 
into pus and débris; all traces of rods, cones, and nerve cells, have disap- 
peared. The portion adherent to the optic is of a dirty drab colour, and 
loaded with leucocytes,
