80 CORRESPONDENCE OF RAY. 



Somewhat after the receipt of yours, I found another 

 insect, which I guess will yield an acid juice, for it most 

 fiercely strikes the nose with a fiery and acid smell, just 

 after the manner of the bruised bodies of pismires. This 

 insect hath no sting, and is the long and round-bodied 

 lead-coloured Multipeda or lulus. Methinks the juice of 

 that creeping Flammula about Montpellier was, as far as 

 I remember, much like this of pismires. 



My hearty humble service to Mr. Willughby. If you 

 try the experiment of gilding, remember that the scum 

 be suffered to become a little stiff and firm, otherwise it 

 will be apt to break into very small pieces in the filter, 

 and not show so well. I might inclose part of a gilt 

 filter, but that it is so apt to break and wear off with the 

 lightest touch. 



I pity your pain, which I begin to know a little myself; 

 but in truth I know no certainer remedy than one grain, 

 or less, of laudanum dissolved in spirit of wine. This 

 never failed to ease me. 



I thank you for my Book of Proverbs; I am much 

 pleased with it, but my wife will have it her book. Adieu, 

 my dear friend.

Our sycamore bled yesterday at the breaking up of a 

 seven days' continued frost, and I am now apt to believe, 

 if I had had the care to have made new wounds upon 

 every like change of the weather, that our York trees 

 would have bled before now. But I affirm no more than 

 I have seen and tried. 



Mr. RAY to Dr. LISTER. 



DEAR SIR, 1 have not yet had the fortune to strike 

 any other trees that would bleed, besides maple, vine, 

 sycamore, walnut, birch, and willow. I have heard that 

 the quicken and aspen trees will sometimes bleed, but I
