60 CORRESPONDENCE OF RAY. 



Mr. Wrat to Mr. Listek. 



Sir, — For my own part, I have made few discoveries 

 in plants this summer; only I have observed Gramen 

 agrorum venti spied. Lob. [Agrostis spicd-venti, Linn.], to 

 grow very plentifully among the corn in the sandy 

 grounds in this country, and have now seen the Folemo- 

 niumpetrcBum, Gesn. [Silene nutans, Linn.], in flower and 

 seed all about Nottingham Castle, on the walls and rocks. 

 The Pink [Dianthus deltoides, Linn.] which grows by the 

 highway sides of the sandy hill you descend going from 

 Nottingham to Lenton, I find to be the same with that 

 which grows on the hills about Sandy, in Bedfordshire, 

 near Juniper Hill, in Cambridgeshire, Bridgenorth, in 

 Shropshne, and in many places of Berkshire. Thomas 

 WilUsell sent me Jhinefoliis hederaceis rutce modo divisis 

 [Veronica tripliyllos, Linn.] (if I mistake not I use Bau- 

 hine's name), which he found somewhere in Norfolk, and 

 a sort of Willow [Salix amygdalina, Linn. ?] growing 

 about Darking, which, as he saith, casts its bark, and 

 stands bare some part of the year. Mistletoe growing 

 on the Hazel I took notice of this spring near Braintree, 

 in Essex, but that is a thing scarce worth the mentioning. 

 Your experiments concerning the motion of the sap of 

 trees do marvellously agree with those we have this year 

 made, as you may perceive by a letter of Mr. WiUughby's, 

 inserted in the Philosophical Transactions, wherein there 

 is a bad mistake, which perverts the sense, of the word 

 morning instead of noon. Mr. Willughby presents his 

 service to you, and wonders you should stick so to the 

 number of thuty-one species of spiders ; whereas, either 

 he deceives himself, or he hath found out many more, 

 and believes there may be, at the least, double that num- 

 ber in England. In your table of spiders, I do not well 

 understand the term scutulata, whether it be to be un- 

 derstood of the texture and meshes, or the figiu-e of the 

 webs. Pardon this confused jumbling of things to-
