62 CORRESPONDENCE OF RAY. 



Linn.], an elegant plant (and, as I think, not described), 

 on the banks of the river Tees. Vitis idaa tnagna qui- 

 husdam^ sive Myrtillus grandis, J. B. [Vaccinium uligmo- 

 sum, Linn.], in Cumberland, at a place called Orton, in 

 the midway between Hexham and Pereth. These I have 

 inserted in the Appendix of my Catalogue, which now 

 goes on apace, I having received six sheets more since I 

 wrote to you, which reach as far as the beginning of M. 

 The Appendix is now grown, I think, as great as one 

 fourth part of the book, I having gained several new 

 medical observations, which I hope may be of good use. 

 This summer we found here the same horned Eruca, 

 which you and I observed about Montpelier, feeding 

 on Fcenicuhim tortuosum [Seseli torhiosum, Linn.] Here 

 it was found on common Fennel. It hath already under- 

 gone the first change into a chrysalis, and we hope it 

 will come out a butterfly before winter. I must depre- 

 cate your displeasure for publishing to the world (in case 

 Mr. Oldenbergh print my note, as I believe he will), that 

 Dr. Hulse was the man from whom I had the first notice 

 of spiders projecting their threads. The observation is 

 yours as well as his, and neither beholden to other (that 

 T know of) for any hint of it, only he had the hap to 

 make it first ; and being questioned about it, I could do 

 no less than own the first discovery of it, to me, to be 

 from him, who indeed communicated it to me so soon as 

 I saw him, immediately after my return from beyond sea. 

 I long for an account of the fruit of your summer's sim- 

 pling. I believe few things thereabout will escape your 

 notice ; and yet you are in one of the best quarters of 

 England for variety of choice simples. I would not have 

 you think of buying my Catalogue, for I design you one 

 so soon as it is printed, if I may know how to convey it 

 to you. Let me not lose your love and friendship, which 

 1 do very highly prize ; and therefore should be loth to 

 do or say anything which might give you any displeasure, 

 or alienate your mind from me, or in any measure abate
