consider it Arbor alba minor of the same author, This idea 
was encouraged by finding our trees agree, in most respects, 
hetter with Rumph’s description of the latter, than with the 
former, and particularly because he expressly says that an 
essential oil is obtained by distillation from the leaves of che 
small sort; but makes no mention of any such oil being pro- 
cured from the large species, These conjectures have receiv- 
ed additional support, I may say confirmation, from the 
Pharmacopeia above quoted. The following is a copy of 
Dr. Powell, the translator’s note, on this subject, 
“ This oil was supposed to be the produce of the Melaleu- 
ca Leucadendron, but it appears from the specimens of the 
tree yielding the true Cajuputi, sent home by Mr, Christo- 
pher Smith, that the species is different, and referable to 
tab, 17 of Rumphius’s Herbarium Amboinense, (vol, xi, ) and 
not to that author’s 4rbor alba, tab. 16. After a careful ex- 
amination of specimens in Sir Joseph Banks’, and other col- 
lections, by Dr. Maton, and of those in the Linnean Herba- 
rium by Dr. Smith, we are authorized to consider the tree 
which yields the above oil, asa new species, and from the 
names of its medicinal product, those gentlemen have agreed 
to give it the appellation of Melaleuca Cajuputi.” 
As there are two figures in the 17th table of Risaihine 
Dr, Powell should have specified which of the two is meant, 
but | take it for granted that it is the Ist.
