Being uncertain of the address of Mr Ehrhart, 

 I have thought it safesl to cornmunicate wilh You, 

 Sir, on the snbject of the Supplementum Plantarum, 

 he having entrusted to you the superintendance of 

 ihe printing of that work in his absence. 



What principally displease me are pages 69 — 74* 

 conlaiuins; ihe following genera of Mosses — Hcd- 

 wigiaj Pottia, Georgia, Grimmia, Webera^ Catha- 

 rinea, PVeissia, and Andrewa — with which I ha- 

 ve no sort of concern. Every body will think me 

 mad, if these should come forth under my aulho- 

 rity; especially as I have, this very year, in an 

 academical dissertation already published, reformed 

 the genera of Mosses, according to principles of 

 whose solidily I am convinced; and have also, in 

 the same work, given names to several of them. I 

 would thereibre have the above pages, containing 

 these genera, cancelled; or the whole sheet may be 

 reprinted. An interval in the paging would be of 

 no consequence. If Mr. Ehrhart is desirous that 

 the genera in question should be published in this 

 work, they may form an appendix; but in his na- 

 me, not in mine. Nothing could be more unexpec- 

 tf d on my part. No explanation can ever convince 

 me of the propriety of allowing these genera to re- 

 main as they are, if the work is in any respect to 

 be attribuled to me." *).

 The sheet alludcd to was cancelled; but the editor was fa- 

 voured, by Mr Ehrhart, with an impression. The discar- 

 dcd gcncra, with their characters, are published in this au-
