It is obfervable (to endeavour a Solution) that fome of the 
Ichneumons delight to feed of a liquid matter, a$ the Eggs of 
SpiderSj the juices (if not Eggs) within the bodies of Cater- 
pillars and Maggots : Whence we conjeiture, that thofe of 
the fame Genm, to be found in Vegetable Excrefcencies, may 
in like manner fuck-in the juices of the equivalent parts of 
Vegetables^ And this the dry and fpongy texture of fbmc of 
th»ie kind ofExcrefcenciesfeems to evince: For^ if you cut 
in pieces a Wild-poppy-head y for example, (or the great and 
fofc balls of the Oakj you I find in thofe partitions, v/herein 
thefe worms are lodged^ nothing buc a pithy fubftance like 
that of young Elder; and if there chance to be any cells yet 
unfeifedjCwhich I have fometimes obfervcd)the feeds therein 
will b^ found yet entire and ripe. Whence very probably they 
ieed upon'or fuck-in by little and little the yet liquid pulp of 
the tender feedf^md leave the fubflancc or fibrous part to be 
expanded into an Excrefcence^ 
Asformatter of Fadij to clear the truth of that opinion^ 
that the divers races of Jr^«^a!;72<?»/ are generated by their re- 
fpecliive Animal-parents, and particularly that thofe, which 
the divers Excrefcencies of Vegetables jprpducc, are not 
■^lantigenous, I am in great hopes, the infl:ancc ef Poppf heads^ 
ifwoln into Excrefcencies, will favour us the next feafon* My 
expectation is chiefiy grounded upon the condition and na- 
ture of that plant 5 which is fuch , that nothing can pierce 
the skin of it and wound it but it muft neceiTarily leave a mark 
of its entry, the milky juice fpringing upon the lightefl pun- 
cture, and drying and concreting fuddainly into a red jfcar.* 
And this, I think, 1 may affirmjthat of the many heads grown 
into ExcrefcencieSj which I gathered this Summer, all had 
more or lefs of thofe marks upon them. But our aim is here 
©nly to make way for the Obfervation againft the next 
feafon 5 to which purpofe alfo we propofe the following 
§limre^s > 
I* Whether the fhagged balls of the 7?oy^^ are not Ex- 
crefcencies grown from the bud and very f 1 ic of the plant - 
lake as the WHd'Foj)pj'hciid^ are apparently not for worms 
to feed*.
