On the American Locust. 187 



the locusts have been in the same district. — But it is 

 not necessary to take up any time in proving, that these 

 two animals are no way transmutable into each other. 



There are other opinions relative to the locusts not 

 less extravagant than the one just mentioned : such as 

 that after the insect is hatched, it descends, from the 

 branch in which the parent egg was deposited, between 

 the wood and the bark, into the earth. 



Dr. Jones mentions a curious fact; that he " never

 of the locust. Were the female to deposit her eggs in 

 the twigs of such trees, abounding with a strong viscid 

 resinous matter, they never would be hatched; or, if 

 hatched, great numbers of the young would perish.
