receptacle. The resulting dust is the final snuff. [tis kept 
either in asmall glass bottle, tightly corked, or else, more 
traditionally, in a type of jar made, as Koch-Griinberg 
described, from a large snail-shell to which a hollow bird- 
bone tube has been fixed with pitch. This tube is stopped 
with a plug of feathers glued together with pitch at the 
basal end to form a tight-fitting stopper. 
The consumption of yakee-snuff is limited to medicine- 
men and is, therefore, small. Since it is said to lose its in- 
toxicating properties rather rapidly, even when in a tight 
container, it is made in small amounts and frequently. 
VI. 
It may be of interest to append a few observations 
which I was able to make personally after taking yakee- 
snuff. I took about one-third of a level teaspoonful of the 
drug in two inhalations using the characteristic V-shaped 
bird-bone apparatus by means of which the natives blow 
the powder into the nostrils. This represents about one- 
quarter the dose usually absorbed by a diagnosing medi- 
cine-man, who takes about one slightly heaped teaspoon- 
ful in two or three inhalations at close intervals (of ap- 
proximately fifteen or twenty minutes). 
The dose was snuffed at five o'clock one afternoon. 
Within fifteen minutes a drawing sensation over the eyes 
was felt, followed very shortly by a strong tingling in 
the fingers and toes. The drawing sensation in the fore- 
head rapidly gave way to astrong and constant headache. 
Within one half hour, there was a numbness of the feet 
and hands and an almost complete disappearance of sen- 
sitivity of the finger-tips; walking was possible with dif- 
ficulty, as in a case of beri-beri. Nausea was felt until 
about eight o’clock, accompanied by a general feeling of 
lassitude and uneasiness. Shortly after eight, I lay down 
in my hammock, overcome with a heavy drowsiness
