therefore would be expofed to be devoured by fmail birds, or even 

 hy common ants ; for I faw, that where an ant could find its way 

 into the bloflbm, it had eaten up part of the Maggot or cryfalis- 

 But thefe Maggots when enclofed within the bloflbm, do bite or 

 gnaw the velTels of its leaves in a manner, that not only the buds 

 dry, but are dole fhut up, and thus afford a defence to the Mag- 

 got during its growth, and until it is changed into a flying ani- 

 malcule. 



In thefe my obfervations, many things occurred to me worthy of 

 note : firll:, that in all the bloflbms I examined, I never found 

 more than one Maggot in each flower ; fecondly, that from the 

 fmall nourifliment it there received, it grew apace; and lafl:ly, that 

 in a few days it became fo perfedt, as to be transformed into a 

 cryfalis. 



Many of thefe bloflbms I pulled from the trees, concluding that: 

 no flower which contaiiaed a Maggot or a cryfalis, would ever pro- 

 duce any fruit. Placing fomc of thefe before the mifcrofcope, I 

 perceived that the crylalis and the young animal it would produce, 

 bad no affinity with the black Flies I have mentioned ; and to be 

 more certain of the fact, I put into a glafs tube four of thofe cry- 

 falcs, which I carried about with me in my pocket, and at the end 

 ©f five days, I perceived one of them had changed its pale yellow 

 into a red or blackifh colour, and foon afterwards it put ofl' the 

 Ikin which inclofed it, and ran about the glafs : on the eighth, 

 day the three other cryfales put off" their Ikins, but fome of them 

 were of a darker colour than others, having relpedl to the time they 

 had been in their cryfalis ftate. 



I now perceived that, with many others, I was miftaken, in fup- 

 pofing the blight, or rather the Maggots we perceive in the blof- 

 foms of fruit trees, to be produced by the black Flies ; for thefe 

 animalcules, I was now obferving, had, as I before mentioned, no 

 limilitude to the bodies of the black Flies ; firfl^, becaufe they were 

 not nearly fo large ; and fecondly, becaufe that which 1 found
