Ray. 235 
Mr. DooDY ^ emendations and additions, 
by Dr. Tancred Robinson ; and a cata- 
logue of thirty-four fpecies, common both 
to England and "Jamaica^ communicated by 
Dr. Sloane. In this work, Mr. Ray has 
thrown the obfervations on the qualities 
and ufes into the index. 
From this time the Synopsis" became 
the pocket companion of every EngHjh bo- 
tanift. It contributed not a little, both to 
facilitate and improve the fcience. It dif- 
fufed the knowledge of fyftem ; and, by ob- 
liging thofe who wifhed for improvement, 
to attend iriOfe minutely to generical cha- 
ra£lers, led to a nicer difcrimination of 
both genera and fpecies.
