dife, and the clearing out of fliips, have 
been the means of difperhng many. The 
EngHp Flora, as it now Hands, cannot con- 
tain fewer, perhaps, than fixty acknowledged 
fpeeies , and a critical examination would 
probably inveftigate a much greater num- 
ber. 
In the Fourth Century of the fame work^ 
we find a critical differtation on the f Cahve ) 
coffee of the Arabians : and on Eziropean 
coffee, or fuch as may be prepared from 
grain or pulfe. Dillenius gives the re- 
fult of his own preparations made with 
peale^ beans, and kidney beans j but fays, 
that from rye comes the neareft to true 
coffee, and was with difficulty difringuiflied 
fi'om it. 
In the Sixth Century, he has defcribed 
and figured four fpeeies of dubious plants ; 
three of t\it Spergula gtnxxs, now Are?2arice ^ 
and a Veronica, 
In the Appendix to this Ceittmy, Dil- 
lenius gave the firfi: fpecimen of his ac- 
curate examination of fome plants of the 
Cryptogamous clafs which he afterwards 
purfiied fo greatly to the improvement of 
botany.
