BALANCE, Cream, Wisconsin Hydrostatic. This balance has been devised to meet the demand 

 for a simple and correct method of weighing cream into test bottles and consists of a specially 

 devised brass float, which is placed in a cylinder of water. Very accurate weighings -can be 

 made with this instrument, and as there are no bearings to rust it will retain its sensitiveness 

 indefinitely. Complete with metal cylinder, float and 9 gram weight, but without bottle . . 5.50 



BALANCE, Decimal Milk. This spring scale is intended especially for use in connection with 

 the Babcock Test for keeping records of the quantity of milk from individual cows, together 

 with the percentage of fat, so as to calculate the butter yield. The scale is provided with a 

 loose pointer, which by means of a thumb screw may be set anywhere on the dial to offset the 

 weight of the milk pail. The readings being in pounds and decimals of pounds makes the cal- 

 culation very much simpler than when pounds and ounces are given as on the ordinary scale. 

 (Decimal divisions not shown in the illustration.) Capacity, 30 pounds, weighing by 1/20 pound
