1 Cc N/10 acid per 100 grams (Methyl Orange, indicator). 
From the figures given in Table 6 it would appear that the follow- 
ing are conservative maximum values for unneutralized cream: 
Alkalinity of ash on fat-free basis (cc N/10 acid per 100 grams) 80. 00 
CaO in cream on fat-free basis (per cent) 0.20 
CaO in ash (per cent) 25.00 
ANALYSIS OF DAIRY PRODUCTS MADE FROM UNNEUTRALIZED 
CREAMS. 
A number of analyses of butter churned from unneutralized cream 
were made at the Denver laboratory during the year 1913. The ash 
data are given in Table 7.
