of greater diameter, or at least stain more clearly a deep brown black

Contrary to the results obtained by Drascu with chloride of gold, 
I have not been able to find many ganglionic enlargements at the 
junctures of nerves in this subplexus, rarely they do not occur, but 
are small and not prominent in the field. 
Terminations of the nerves in the epithelium of the closed fol- 
licles, or even adjacent to it, I have not been able to discover, during 
the first part of the investigation I did consider some very fine nerves 
apparently ending close to or between the epithelium, as the possible 
beginning of a nerve termination, but more extended research upon a 
much larger number of sections showed conclusively that they were 
exceedingly fine fibres belonging to the glandular plexus, and further 
on recommunicating with it. 
Around the whole circumference of the solitary glands, the fibres 
of the Lieberkühnian plexus collect in augmented numbers, branch 
repeatedly into finer ramifications, anastomose all over the surface of 
the gland into a finer meshed and very close network of fibres, but 
into the interior structure of the glands they never penetrate, or, at 
least are not stained within its borders. Even in the most outward 
portion no trace of a fibre can be seen, no matter how well stained 
the nerves immediately surrounding it may be. It is highly probable 
therefore that the nerve influence to the glandular structures of the 
intestine is an indirect one, from nerve terminations that are situated 
beyond its proper limit, though so far these terminations, in whatever 
form they may be, excluding the fine delicate network, have escaped 
my observation, a possible defect due to the silver stain itself. 
The second sub-plexus, the villous, is very much more satis- 
factory to study, its staining is less difficult to accomplish, the re- 
ductions are more constant, and both nerves and their final termination 
are brought out more satisfactorily than the Lieberkiihnian. The nerve 
bundles, after passing the muscular lamina, ascend either perpendicu- 
larly, or at various angles to the thin stem of the villus, the con- 
nection between the plexus of MEISSNER and the nerve to the villus 
being made out with great frequency and ease. The bundles, or single 
nerves, ascend waving but unbranched to where the villus begins to 
spread out, then usually one or more of the nerves thicken percep- 
tibly, and at the same time rami are thrown off, dichotomously, with 
great frequency, both from the thickened and unchanged stems. Other 
nerves are seen apparently thickened from the twisting together of 
several stems forming an irregular cord, giving with high powers a
