FIG. 1. 



Showing the apparatus arranged for heat- 

 ing the milk before the pail is covered. 



FIG. 2. 



Showing the apparatus arranged 

 for cooling the milk. 



The apparatus consists of a pail for water and a receptacle for the bottles of 

 milk. 



The pail is a simple pail with a cover. Extending around the pail is a groove 

 for indicating the level to which the pail is to be rilled with water. Inside the 

 pail are three supports (c) for holding the receptacle. 



The receptacle for the bottles of milk consists of a number of hollow cylinders 

 fastened together. Surrounding and binding together the group of cylinders 

 is a wire (A). It is this wire (A) which rests on the support (c) when the milk 

 is being heated (Fig. 1). Below the wire (A) are three short wires (B). These wires 

 (B) rest on the supports (c) when the receptacle is raised for cooling (Fig. 2). 



1. Fill the pail to the level of the 

 groove with water, cover it and put it 

 on the stove to boil, the receptacle for 

 the bottles having been left out. 



2. Fill the body of each bottle with 

 milk or some modification of milk in 

 proper proportion for feeding; stopper 

 with a wad of cotton batting and put 

 in a refrigerator. If all the bottles 

 which the receptacle holds are not 

 needed, rill the remaining cylinders 

 with cold water. Each space in the re- 

 ceptacle must be filled. 



3. When the water in the pail on the 

 stove boils thoroughly, take the bottles 

 of milk from the refrigerator and put 

 them in the spaces for them in the re- 

 ceptacle. 



4. Pour cold water into each of these 

 spaces so as to surround the body of 

 the bottle. 



5. Take the pail of boiling water 

 from the stove and put it on a table or 

 mat. Do not put it on metal or stone. 

 Be sure that the pail is still filled ex- 

 actly to the level of the groove and that 

 the water is boiling vigorously. 



6. Set the receptacle containing the 



bottles of milk into the pail of boiling 

 water, so that the wire (A) will rest on 

 the support (c), cover the pail quickly 

 and let it stand forty-five minutes. 

 During this period the pail must not 

 be on the stove and the cover must not 

 be removed. 



7. Now uncover the pail and lift the 

 receptacle and turn it so that the wire 

 (B) will rest on the support (c), thus ele- 

 vating the top of the receptacle above 

 that of the pail. Put the pail contain- 

 ing the receptacle elevated in this 

 manner in a basin, under a faucet to 

 which a rubber pipe may be attached 

 connecting it with the pail (Fig. 2). The 

 water will overflow from the pail into 

 the basin. Or the pail may be stood 

 under a pump, fresh cold water being 

 pumped into it every few minutes. 



The above described method of cool- 

 ing is the best. When, however, it is 

 not possible to cool the milk in this 

 way, the cooling may be accomplished 

 by placing the receptacle containing 

 the bottles of milk in iced water, or by 

 simply standing the bottles on wood in 

 a refrigerator.
