it is possible to obtain only the latter type of hydrometer, Table I may 

 be consulted for obtaining the actual percentage of sugar. For cider a 

 Brix hydrometer reading from 0° to 30° is desirable. A medium grade 

 Brix hydrometer for sugar costing seventy-five cents is listed as No. 

 7774 in the catalog of the Central Scientific Co., Chicago, Illinois. A 

 hydrometer jar for use with the hydrometer is No. 3650E at fifty cents.

 cider to be tested for its sugar content must be cooled down or warmed 

 up to the degree Centigrade or Fahrenheit for which the saccharimeter 

 is regulated. This teiiiperatuie will be stated on the hydrometer.
