A QUESTION has been afked, to which it may be neceflary here 
briefly to reply, viz. Why we have not figured all the Plants enume- | 
rated in the Catalogues of the Firft Part of MepicaL Botany, 
but have omitted Hordium di/ichon, Triticum hybernum, Avena fativa, 
Piper Cubeba, Santalum album, Amyris Elemifera, Myroxylon peruj- 7 
Serum, Stalagmitis Cambogioides, Boletus iguiarius, Cocos butyracea. 
Tue three firft, barley, wheat, wed oat, are fo well known, 
and have fo little claim to a place in Medical Botany, that it was 
fuppofed a majority of our readers would deem their figures fuper- 
fluous. Befides, their feeds are unqueftionably to be confidered as 
articles of food rather than of medicine. Of Piper Cubeba, Santa- 
lum alii, Myroxylon peruiferum, Stalagmitis Cambogioides, and 
Cocos butyracea, we have not been able to procure proper {pecimens, 
nor are there any perfect figures of them publithed ; fo that the plates 
of thefe were unavoidably omitted. Refpecting the Amyris Elemifera 
Lin, we have to obferve, that after fully inveftigating the authorities for 
admitting this to be the tree which produces the officinal drug 
Elemi, we are convinced of their infufficiency, and that the name 
Elemifera is diene erroneoufly applied; and therefore, though we 
obtained a good fpecimen of this fpecies, we had no plate of it 
engraved, : 
BoLetus igniarius, or agaricus chirurgorum, is not properly a 
medicinal article, nor is it of much importance in furgery; and
