 no small significance is the fact that the altered 

 individual units have attached themselves to the 

 floors and the walls of their artificial homes; this 

 attachment being accomplished by their secreting a 

 firm horny substance, sheath-like and almost com-

With quickened pulse I watch the transformed 

 animals. And even as I look, further slow and 

 delicate changes take place. Around the rims of the 

 cup-like forms, prominences begin to appear. 

 Finally each larva is adorned with a corona of
