174 CORRESPONDENCE OF RAY. 



Your former conjecture, that there may be a different 

 place, I cannot allow, because those who write of it say 

 it is near Grenoble, as this was ; and we, inquiring upon 

 the place, heard of no other but this ; and that this is 

 that which is usually visited by travellers one may know 

 by the hackney-men, who are very well acquainted with 

 it ; and Golnitz, in his ' Itinerary of France,' notes this 

 for the " Fontaine que brule." But enough of this. 

 Another thing I meet with in the same ' Transactions ' of 

 January last, in Mr. Waller's observations concerning the 

 Cicindela volans, of which I am in doubt, though I confess 

 I am more inclinable to believe what Mr. Waller asserts, 

 that both male and female have wings, it being more 

 agreeable to the analogy of other insects, besides the 

 credit of the person who saw them in copulation. But 

 then what shall we say to Carolus Ventimiglia, to whom 

 I am loth to give the lie. Indeed, if his credit were as 

 good as the relator's, E. Columna, I dared not. " Cum 

 enim (saith he) ex nudis plurimas haberet in vitro inclu- 

 sas, animi causa alatam captam iis adjecit, qua3 continuo 

 se spectante unam ex nudis subegit, eique adhaesit ut 

 bombyx solet, ab ea deinde divulsa aliam atque aliam, 

 quae sequenti die parere cceperunt,'' &c. Besides, how 

 came this to be the received opinion before ?

SIR, Take a Pilchard \ClupQa pilcliardus\ by the tip 

 of the back-fin, and it hangs in equilibrio, but a Herring 

 [Clupea harengus\ so held sinks headlong. This was 

 tried lately. 



M. Dodard affirms that he hath frequently found be- 

 tween the bark and the wood of old hornbeam trees a very 

 odd vegetable substance, having black membranaceous
