CORRESPONDENCE OF RAY. 43 



Mr. WHAT to Mr. LISTER, at Nottingham. 



DEAR SIR, Having now received a second letter from 

 you in English, I look upon myself as licensed to answer 

 you in your own language. I am extremely obliged to 

 you for the catalogue of plants you sent inclosed, they 

 coming very opportunely, now that I am (chiefly by your 

 instigation and encouragement) revising and preparing 

 for the press my general catalogue of English plants, 

 which I hope to finish and get published by the next 

 spring. I shall go over all yours, and give you an account 

 which are to me unknown, and which I have not yet met 

 withal m^ngland. 



Muscus dcnticulatus major, Park. \_Lycopodium helveti- 

 cum, Linn.*], which you say grows plentifully in springs, 

 it was never yet nry fortune to find in England. 



Muscus corniculatus,^ Park., is frequent with us here- 

 abouts, and with the like scarlet tops. 



Muscus clavatus, sive lycopodium \_Lycopodium clavatum, 

 Linn.], grows, as you well observe, on all the moors in 

 Yorkshire, Derbyshire, &c. plentifully, and on Hanip- 

 stead-heath, near London. 



Muscus clavatus cupressiformis, Park., or Sabina syl- 

 vestris Tray. \Lycopodium alpinum, Linn.], I have observed 

 plentifully on Ingleborough-hill, and also on Cader Idris 

 and Snowdon Hills, in Wales. 



Your moss, like the pine-tree, I suppose is the same 

 which I call Muscus erectus abietiformis \Lycopodium se- 

 , Linn.], and have found on many of the moors. 



Tilia foemina is a tree very common in Essex, and 

 many other counties of England ; 1 mean the Fcemina 

 minor of Park. [T. parvifolia, Ehrh.], for the major [T. 

 europaa, Linn.], I have not as yet seen anywhere with us 

 spontaneous. I know not what to make of the Tilia 

 mas, but suspect it to be all one with the Carpinm, or 

 hornbeam.
