CATALOGUES. 569 



London Catalogue, because Dr. Boswell Syme assures me, in 

 1873, that he has never found the nos. to the names " of the 

 least use." My own experience of them -was, and stiU is, widely 

 different indeed. I dislike much to receive a manuscript list 

 of plants or localities, in which the plant-names are not written 

 in the same sequence, and with the same nos. affixed, as seen in 

 the London Catalogue. But a list of mere nos. without names 

 has usually got thrown into the fire forthwith.
