 33^ per cent. Where cow's milk is not readily obtained, con- 

 densed milk can be used. A can of milk as sold in stores

 milk, 1 can equals f pints, water (double the quantity of con- 

 densed milk), 2 cans equals 1^ pints — 36 jjer cent. In appli-

 rate of one part of l)utter to from twelve to sixteen parts of 

 water, or. in other words, one part should be diluted with 

 water from twelve to sixteen times."
