ComposiTION oF SHELL AND Husk.—We have already alluded 
to some of the uses to which the shell and husk of the cocoanut 
are put by reason of the chemical and physical qualities they poS- 
sess. Some facts regarding their chemical composition were give? 
in the table on page 335. 
The following percentage results of ‘elementary analysis of the 
powdered shell were obtained by Baumhauer ;§ all samples having 
finally been thoroughly extracted in alcohol and ether, and then 
dried at 120°-150° C.:

*. According to Dietrich and Kénig (Konig, Menschlichen Nahrungs- und * 
nussmittel, etc., 1: 612. 1893) the air-dried substance contains the following iP Pf 
centage of the total dry weight : 
Total Substance Soluble in Water, Proteids Soluble in Water. Sugar (Sugar-Vielding Substance): 
15.16 2.27 9.25 
as The factor 5.5 is used because the proteids of the endosperm contain 18 per en 
of nitrogen. See references in this connection on page 341, footnote. 875
