shell. R H affirmd he had seen them come out /of/ them aliue the rest of the shell re
maining tostick to the place where its way was first Layd
mr. Henshaw obserued that all wormes in nutts proceed from wthout by eating a way into
the kernell which way in a short time cloaseth vp but leaus behind it a kind
of cicatrix. the like was affirmd of the wormes in Galls oak apples and seuerall other excres
sencys /of Plants/. It was obserued that all galls haue either a .. . . hole in them by wch. the worm hath eaten
its way out or els the worme it self may be found in the middle of it
Dr. Croon affirmd that the chicken might be discovrd formd in the cicatricula of the egge by the
help of microscopes. he was desired as soon as conueniently to shew the same at a meeting of this
Society. He complaining of the defect of microscopes for such vses. RH. suggested some further
Improuement of that Instrument by making vse of the conuexity of the surface of the liquor itself
(putt vpon thin plates of muscouy glasse) for augmenting the body wthin the liquor as also for augmen
ting the body beyond th it. the same might be done by small drops of fluids ^/Let fall/on the Leafs of coleworts
or oyled or any oyled or Greased superficies. as also by the small drops at the end of small pipes or
sticking on small threads of glasse or a single clew of silk. the said globular fluids/transparent bodys/ being vieud
by the help of good microscopes. vpon this occasion M Hook mentioned his way againe his way wch
he had formerly acquainted the Society wth. of making microscope glasses wth. smal drops of glasse made
by melting vp the ends of threeds in the flame of a candle into a globular figure and then grinding
all away vpon a flat saue a very small segment of the spherule. and soe made vse of as of a plane
commen glasse either for a single or compound microscope. He was desired to shew some of
.. . . specimen of this .. . . at the next meeting.
