Most of the nuts subjected to the analyses referred to fart . 
on were furnished to us for this work by Hon. Wm. Fawcett ay 
the United Fruit Co., who sent them in their husks from ~— 
They were ripe, fresh and of about the average size. A few ME 
terminations were made with material from nuts bought in 
markets in this city—source unknown, though doubtless of — 
Indian origin. These were of ordinary size, appeared to gee 
and fresh, and gave essentially the same analytic results as thos 
ined directly from Jamaica.* 
Kets wish ci ee of this paper to thank Dr. Mach 
not only for the supply of material with which he favored us, Ae 
also for the suggestions which led us_to undertake this work an 
for the kind encouragement he has given us from the beginning.
