present as existing In the albuminoid form. It was found, howe 
that by the phenol method, the per-centage of coagulate albuminoids did 
not exceed 12°53; this. shows that, in the original flowers, out of 2:632 
per cent. of nitrogen, 0°65 existed in the form of amides and eren 
ies. No starch could be detected, but abundance of sugar 
present; the 46 per cent. entered under this head includes, however; 
some gum or mucilage. The potash and phosphoric acid in the ash were 
both high. 
“ The chief ham end of ge flowers, from a dietetic point of view, - 
is their richness in enous compounds. The ratio of albuminoids 
is as 1 to 4° e corresponding nutrient ratio in rice is as

foods which a e poor in nitrogen. And if we assume 16:7 per cent. of 
albuminoids to be present in phog, then this nutrient-ratio will come 
out still better, namely, a proportion which corresponds pretty 
at in chickpeas. It should ad at there is rather 
close resembla in composition between phog and the seeds of the

edible amaranths and buckwheats, only sugar replaces starch, 
CVIL—EARLIEST NOTICE OF COCA. 
In the article on Coca in the January number of the Kew Bulletin 
it was stated that the earliest account in literature of the well-known 
published, aecording to Pritzel, a E Diaz in Seville in 1580, 
and he calls this a posthumous editi 
The well-known iade Dr. Eras, Professor of Natural History in 
the University of Caracas, Ven uela, in aletter dated February nd, 
on vn Eie 22d pointed out thé following grounds for believing that

edition of 1580 by Fernando Diaz is the second of the collected pi 
of Monardes. It is therefore not correct to say that this Mee my was 
printed after its author's death. Monardes died 1588, as has been 
proved by Morejon (Historia bibliografica de la visti espanola, 
Madrid, ii, 290). Meyer has taken from this source what he says 
about Monardes (Geschichte der Botanik, i., 412). The mistake about 
the year in which Monardes died comes from Antonio, who says in his
