this man fearched for the Maggots with me ; I put fome of them in- 

 to a box, but in a fliort time they partly flirivelled up and died ; 

 others of them I put on a turf of grafs, which I placed in an earth- 

 en vefl'el, and watered it every day ; this veflel I fet in my ftudy, that 

 I might remember to view it frequently, and when the grafs began to 

 wither, I replaced it with a frelh turf : in doing which I faw more 

 of the Maggots lie Hill on the earth, I thereupon took the turf which 

 began to wither, and, taking from it the Maggots, I placed them on 

 the frelh turf : and this I continued to do till the end of July, in all 

 which time I perceived no alteration in the Maggots. In the mean 

 time I chanced to be in the company of fome gentlemen of refped- 

 ability, with whom converfmg on this fubjed, they told me that 

 thefe Maggots would be changed into flying animals, called, in our 

 language, Speketers. But, though I was well allured, in my own 

 mind, that fome fuch change would take place in thefe creatures, I 

 determined to fupply them with frefli earth, until I fliould fee their 

 transformation. 



In the beginning of Augiift the turf again began to dry, and, con. 

 lidering that fo long as three months time had now elapfed, I exa- 

 mined the turf, and took the Maggots out of the earth, when I faw 

 one of them, which was whiter than the others, to be fomewhat con- 

 tracted, whence I judged that its transformation was at hand; where- 

 upon I placed it and two others of the Maggots in a box, and the 

 next day 1 faw one of them was changed into an aurelia or cry- 

 falis, having put off its fkin, which lay belide it. I fought for ano- 

 ther of the Maggots which was changed into a cryfalis, but which 

 I had not fliut up in a box, and, not finding it, I concluded it had 

 changed into a flying animal and efcaped. The other Maggots were 

 in a Ihort time contraded, but did not undergo any further change.
