the smaller axis; a very remarkable linear or moniliform ar- 
rangement of granules presented itself in certain parts of the 
field, sets or rows of granules being arranged longitudinally 
parallel or convergent, and apparently in connexion with very 
faint subjacent striations in the same direction—I am inclined 
to regard this as an instance of granular disintegration of a 
band of fibre;—lastly, numerous stellate crystals, apparently 
of the fatty acids, lay scattered over the field, some also being 
included in cells, and appearing to be the stage of lysis of their 
previously granular contents, preparatory to the final rupture 
and dissolution of the including membrane. 
3. Blood.—I have met with specimens of blood in which 
changes took place with great rapidity ; I do not now allude 
to the corrugation and stellate appearance of the corpuscles, 
which is familiar to every one. In one specimen, after 
twenty-six hours, I found the hematine had escaped from 
numerous corpuscles, and had assumed the shape of granular 
masses, heaps, and crystals (hematoid crystals of Virchow). 
What pathological significance to give to this rapid change I 
do not know; but I am inclined to think that this, as well as 
other isolated facts which we now possess in reference to the 
blood, will be one day utilized. 
4. Blood Stains.—This question is so important that I pur- 
pose making it the subject of a special inquiry. At present I 
will only add, that from specimens three months old, Ihave been 
able to figure the corpuscles, though much changed in form ; 
also, a red granular base studded with corpuscles, and hema- 
toid granules more or less aggregated. 
2. Histolysis in Fluid Blood.—Blood of duck after two years 
(kept in a bottle). Here was presented an assemblage of forms 
widely different from those of the natural blood; none of the 
characteristic elliptical corpuscles of this animal’s blood was 
to be found. There existed, firstly, abundance of granules, 
granular corpuscles, spherical vesicles of moderate size; square 
and oblong, apparently vesicular, bodies; large cells or vesicles,
