 In Sulphur Springs. At Croft, Yorkfhire, and Dinfdale, Durham ; 

 Dr. Willan. At Middleton One Row, near Darlington •, Mr. Backhoufe. 

 Although I have not feen any other fpecimens of C. nivea, than thole 

 which I received from Darlington, yet from Dr. Willan's defcription there 

 can be no doubt that it is the plant which he has defcribed. Dr. Willan. 

 fays it is a remarkable circumftance that this fpecies is found below the 

 fpringj no further than the water retains the fenfib':e fulphureous qualities, 

 as if the hepatic gas was necefiary to its production and nourifhment.
