Barthelemy has experimented upon the pupa of Bombyx mori, 
by applying to it a covering of varnish, wax, or oil, in order 
to see whether, during this second embryogeny, effects could 
thus be produced analogous to those manifested in the egg of the 
fowl when similarly treated. By such applications to the an- 
terior parts of the pupa, he succeeded in causing an arrest of 
the development of the cephalic and thoracic portions of the 
insect ; but his most remarkable results were obtained by the 
local compression of the pupa. By this means individuals were 
obtained almost completely acephalous ; and, singularly enough, 
these had the generative organs unusually developed, and mani- 
fested a great desire for copulation. By the compression of the 
extremity of the abdomen the development of the generative 
organs was prevented ; and in this case the moths showed but 
little vigour. In some instances the anal aperture was ob- 
structed, and the moth, being unable to evacuate the meconium, 
by its natural outlet, voided a blackish liquid from the mouth.
