v/hich penili t thè entrance of thè air into 
thè iuirànous segments. In spite of all rny

(suddiafani) elongated 
globules of varying size, w£h a quantit^r cf 
irregular particles, which I rnyseif oonsider 
to be fragirients cf thè globules produced by 
thè breaking up cf many of thè la t ter* By 
this observable way thè .vlobules, which wer

entity, lose their light very easily (by 
rarefication lit.) and thè

I desired afterv/ard to renew this reseroh, 
and prest this material together again, 
but thè light was pale and of short duration*
