Such as confiji of a firm tough flexible matter , formed' 
into fimple tubular fialks , whofe tops are expand- 
ed into the form of little cups . 
This divifion contains the cup-moffes of authors ; 
the fecond order of coralloides of Dillenius ; great 
part of the firft order of lichens in Haller ; the 7th, 
8th, 9th, and 10th order in Michel i ; and the lichenes 
Jchyphiferi of Linnasus. Dr. Hill has conftituted a 
genus intirely of thefe cup-mofles, under the name 
of pyxidium. 
They are common with us on heaths, and other 
dry and barren places. Some of them are proliferous, 
even to the third degree, and form a very beautiful 
appearance. Some have tubercles on the edges of 
the cups, of a beautiful fcarlet colour..

whooping cough in children ; for which it was long 
accounted a fpecihc. To this end it was given in 
various forms. Gerard and Parkinfon recommend
