To prepare composite samples for testing, set 

 the bottles in water at no degrees to melt any 

 cream on the sides of the bottles. Mix well by 

 pouring from one vessel to another. Take the 

 samples as usual but cool to about 60 degrees 

 before adding the acid. Use slightly less acid 

 than for ordinary testing. 



To find the pounds of fat produced during the 

 period the test has covered, multiply the test by 

 the pounds of milk given during that time and 

 divide by one hundred. 



To find the approximate number of pounds of 

 butter, divide the total pounds of fat by six, and 

 add the result to the pounds of fat, and it will 

 equal the pounds of butter.
