Those obtained may be regarded as typical. The samples were 
gotten from open heaps of scrap in the storage house, or from bags 
by means of samplers, or by opening the bags. They were shipped 
in canvas sample sacks. Before analysis, the entire sample was 
ground to a powder that would pass a sieve of 16 apertures per 
linear inch. 
METHODS OF ANALYSIS. 
Samples of 2 grams were dried to constant weight in an electric 
oven at a temperature of about 100° C. The loss in weight was 
recorded as moisture. In this connection it should be said that it 
is believed that possibly some oil also was lost in this operation. Oil 
was determined by extracting with ether a 2-gram sample, previously 
dried to constant weight. Following the extraction, the sample 
again was dried to constant weight and the loss was taken as oils. 
For the extraction a Soxhlet apparatus was employed. In the de- 
termination of nitrogen the official, modified Gunning method was 
applied, and in that of phosphoric acid the official gravimetric 
method was used. The analyses were made by E. G. Parker and 
J. E. Linclemuth, whose results are recorded in the subjoined 
table. The eleventh analysis is reported in this table merely for 
convenience. It is the analysis of pulverized crab shells used as a 
filler for mixed fertilizers. The particular adaptability of this ma- 
terial for that purpose is brought out by the analysis.
