quivocal Generation, which Notion is now as univef- 

 jMly as defervedly exploded j' but by becoming fit Ma* 

 trices to cherifh and maturate Eggs depofited in or on 

 them. I have lately obferved many feggs in the com- 

 xhbn RuJhj juncus Uvis vulg. but I know not yet what 

 Animal they produce. One fort are little tranfparent 

 Bodies , in Shape fomewhat like a Pear or a Retort, 

 lying within the Skin, upon or in the Medulla^ juft a- 

 gainft a brownilh fpot on the outfide of the Rufh, 

 which is apparently the cicatrix of the Wound made 

 by the Fly when ilie put her Eggs there. Another 

 kind, I obferve, which are much larger, and not fo 

 tranfparent , of a long Oval , or rather cylindrical 

 Forrnj fix, eight, or more of thefe lie commonly to- 

 gether acrofs the Rujh) parallell to each other, like 

 the teeth of a Comb, and are as long as the breadth 

 of thtRufe. Thefe, Sir, are only hints to be farther 

 improv'd by you, who being fd converfant with Plants, 

 and defigning aTreafife of Infe£ls 9 may have oppor- 

 tunity of examining them more accurately. I can fee 

 no reafon in the fancy of fome Men who would de-^ 

 duce all Diftetnpers from Infers , yet I am perfuaded 

 they have more fliare in the Produ&ion of fome, than 

 many will imagine. In fome forts of Scabs and Itch 

 I have feen very fmall white Animals taken out with 

 a Needle, and to have been living , and very nimble 

 in their motion. Thefe often make vifible Paflages 

 under the Skin from Scab to Scab, like a Mole under 

 the Earth. Add hereunto Animals taken out of the 

 Gums^ and other Parts, mentioned in the Philofoph. 

 Tranladt. I wifh a good Account could be given of 

 fome Ahimals product with of others, as the 



Lumbrui lati in Men , and of Toads found living in 

 the middle of maffy Stones, &c.
