Table 5 shows that in 394, or 63.2 per cent, of the sales the pur- 
chasers asked for the ice cream that contained 1 per cent of gelatin 
(mix L) ; in 143 sales, or 23 per cent, they asked for the ice cream that 
contained no gelatin (mix K) ; and in 86, or 13.8 per cent, they asked 
for the ice cream that contained 0.5 per cent of gelatin (mix M). 
This shows that when preference was given to ice cream made with- 
out gelatin or with gelatin, the ratio was a little less than 3 to 1 in 
favor of the product with gelatin. 
INFLUENCE OF FAT CONTENT ON QUANTITY EATEN. 
The fat content of ice cream does not seem to have a great effect 
on the quantity of ice cream a person will eat, except, perhaps, when 
it is very rich. A test made with two ordinary grades of ice cream, 
one containing 10 per cent and the other 15 per cent fat, showed that 
the average adult person consumed 341 grams (1.2 pints) of the 
10 per cent cream and 317 grams (1.12 pints) of the 15 per cent cream 
when given all he would eat. 
The test was made by serving groups of from five to seven persons 
from a weighed can of ice cream. After they had eaten all they 
wanted, the can was reweighed, and the total amount consumed was 
divided by the number of persons eating. This was done at 12 dif- 
ferent times, 6 times with ice cream containing 10 per cent fat and 
6 times with ice cream containing 15 per cent fat. The time of this 
experiment was in March and April, 1921.
