common involucrum is bur{t open, and the a- 
pices raifed in the air; fince no fooner do

as they feparated, and refume their former 
figure (¢); does not all this thew, that the

the feed, but to be carried away by the winds, 
left it fhould infect it, by falling oa the fig- 
mata; and that qutopfia teaches the quite con- 
trary to what Mr Ge/ver alledges.
