I Have obferved the two Infe<9:s,which Mr. I{ay faith^ fmell 
of Muskj which indeed they do in an high degree. The 
fmall Bees are very frequent in the Wooles in Lim-oln ffjire^md 
about the latter end ot -*^/?n/ are to be found in paftures and 
meadows, upon the early-blown flowers of a foitof Ranuncu-^ 
luT^ as You have been rightly informM ; but it is fomething 
improper to fay Bees feed on flowers ; And iikewifc the fame 
Bees are do lefs frequent on the flowers of Dens Leonis, 
The frveet Beetle^ is a very large Infeft^ and well known about 
Cambridge, All the trials 1 have.raade to preferve them with 
their fmell, have proved inefFedlual ; For^ bothforts of thefe 
Infects will of themfelves in a very few weeks become almoit 
quite fent-lefs* To thefe I fliall add another fweec-fmelling 
Infedlj which is a Hexapode-worm feeding on Gallium lu" 
teum. 
The Obfervation of theVe/pce Ichneumones^ as it hath rela-

may tell you in general^ that this kind of Jefed: is one of the 
greatefl puzzels in nature 5 there being few Excrefcencies of 
Plants, and very many births of Inf cfts, wherein thefe 
flender Wafps after divers Jtrange w ^ys are concerned. 
Though I be at prcfent from my Booksi^ yet I well remem*

to in Mu^et And he is well able to judge, -k see mmK 
whether the Obfervation be made upon the fame >4- ^.^221.
