 her offspring will shift for themselves. If they 

 fall on the meat, well and good; if they fall 

 elsewhere, they can reach the morsel by crawl- 

 ing. 



This confidence in the unknown factor of 

 the precipice, with no indication but that of 

 smell, deserves fuller investigation. From 

 what height will the Flesh-fly dare to let her 

 children drop? I top the test-tube with an-

 bottle. The mouth is closed either with wire- 

 gauze, or with a paper cover with a slight cut 

 in it. Altogether, the apparatus measures
