having been in spirit, will have lost that transparency 
belonging to them in a recent state, by which they are less 
readily distinguished from blood vessels. 
In this specimen, Mr. Bauer has shown that nerves are 
not only conspicuous surrounding the umbilical arteries, but 
has demonstrated them in the portion belonging to the 
uterus. For the appearance they put on, I must refer to the 
annexed drawing. 
I may here remark, that in no communication which I 
have made to the Society, assisted by Mr. Bauer's labours,

have not myself distinctly seen ; for although I am not equal 
to the nice adjustment of the microscope, which indeed ap- 
pears peculiar to Mr. Bauer, yet, when adjusted by him, the 
appearances before they were described had been rendered 
visible to me. 
In looking at objects so much magnified beyond what 
they appear to the naked eye, it will not be unnatural for 
many of the Members to ask, how I am sure that these are 
really nerves, and not the secondary order of blood vessels, 
too small to carry red blood, and therefore, when their con- 
tents have been coagulated, appear to be chords ^ My

the drawings ; in which it will be seen, that these are not 
continuations of other branches, but form a trellis- work upon 
the arterial trunks, in a manner totally different from any 
thing met with either in the ramifications of arteries or veins \ 
and when they are dried upon glass, they reflect the light
