Leaves, which we have defcrib'd in the Catalogue 

 oi Cambridge Plants, we have feen creep out fmall 

 Maggots to the Number fometimes of Threefcore 

 or more, which fo foon as ever they came forth 

 began to weave themfelves filken Cafes of a yel- 

 low {hining Colour, wherein they chang'd, and 

 after fome time came out thence in the form of 

 fmall Flies with four Wings ; for a full Defcrip- 

 tioHL and Hiftory whereof I ihall refer the Reader 

 to the fore-mention'd Catalogue, The like I have 

 alfo obferv'd in other Caterpillars of a different 

 Kind, which have produc'd no lefler Number of 

 Maggots, that in like m.anner immediately made 

 themfelves up in Cafes. Others, inftead of change 

 ing into Aurelias, as in the ufual Procefs of Na- 

 ture they ought to do, have turn'd into one, two, 

 or three, or more Flefli-Fly- Cafes, at leaft con- 

 tained fuch Cafes within them, out of which after 

 a while were excluded Flefh-Flies. Other Cater- 

 pillars, as that caird the /3//V^;j Maggot, found 

 in the dry Heads of Teafel, by a dubious Meta- 

 7norphofn^ fometimes chang'd into the Aurelia of 

 a Butterfly, fometimes into a Fly-Cafe. You'll 

 fay, how comes this to pafs ? Muft we not here 

 neceffarily have recourfe to a fpontaneous Gene- 

 ration ? I anfwer, No ; the moft that c^n be in- 

 ferred from hence is, a Tranfmutation oi Species -y 

 one Infedl may, inflead of generating another of 

 its own Kind, beget one or more of^a different; 

 but I can by no means grant this ; 1 do believe^ 

 'that thefe Flics do either caft their Eggs -upon the '^• 

 very Bodies of the fore-mention'd Caterpillars,
