ON THE DEVELOPMENT OF THE SPERMATOZOA.

to be in a state of decline after the performance of the generative 
function they are particidoHy numerous in proportion to the other 
corpuscles^ The actual number of them in this case may not be 
increased, but owing to the absence of the other cells which have 
developed into spermatozoa it seems that there are more of them. 
This fact seemed to indicate that they have a connection with the 
blastophoral corpuscle, but a fatal objection to this view is that the 
latter possesses no nucleus, and would have to go through a long 
series of changes before it would resemble one of these ^ brown 
corpuscles,^ of which intermediate phases there are no indica- 
tions whatever. I have repeatedly searched for such phases and 
have never found them. In the very youngest stages of the re- 
servoirs there is no sign of them, but in preparations where the 
sperm-cell segmentation has reached the binary stage it is seen 
that they are represented in a young condition, developing to- 
gether with the true spermatoblasts and the fusiform cells of the 
reticulum. They are in this stage much smaller than the mature 
brown corpuscles,^ and the network is so dense that it is 
impossible to make out its arrangement in detail. I have re- 
presented them at this stage in figs. 67 — 71.
