Set the solution ripen for a week exposed to sun-light. Filter before 
using. Can be used repeatedly. Sections stain in from ten minutes 
to one hour. Discharge excess of stain in forty to fifty per cent 
alcohol, changing two or three times. The celloidin becomes per- 
fectly colorless. Then dehydrate and mount as usual. The best 
results are, perhaps, obtained by staining rather deeply, about thirty 
minutes, and then discharging thoroughly, thirty minutes to one hour. 
Ganglion cells and their processes, axis-cylinders and neuroglia fibres 
(seen especially well around the central canal of the cord) are all 
sharply stained of a deep blue color. Specimens cannot be left more 
than a few hours in alcohol without losing in sharpness and clearness 
of detail. The staining fluid must be kept free from alcohol. Without 
the chloral hydrate a metallic film forms on the surface of the fluid, 
and a sediment is gradually precipitated. The accompanying drawing 
of a PuRKINJE’s cell was very kindly made by Dr. E. STAnLEY ABBOT 
from a section of the cerebellum of KEMMLER, the first man executed 
by electricity in the United States. 
The aqueous solution of phospho-molybdic acid must be saturated 
with haematoxylin in order to get the best results; if, therefore, the 
solution does not stain deeply, add more haematoxylin.
