: he plan of carrying out the experiments. 
_ The experiments, according to the original plan, are divided 
yt ee description of the work done will give a definite idea of 
Series I. 
In the first series the milk is set in Cooley cans under the fol- 
lowing conditions : 
1. Ten pounds of milk, undiluted, are set in Cooley vat in cold 
water. 
_ 2. Ten pounds of milk, undiluted, are set in open room. 
3. To eight pounds of milk, two pounds of water at 35° Fahr. 
are added, making a mixture of ten pounds, containing twenty per 
cent of added water. Set in Cooley vat in water. 
_ 4, The same as the preceding, except set in open room. . iol 
5. Same as 3 except the water added is at 130° Fahr. 
6. Same as preceding except set in open room. 
Series IT. 
In the second series the conditions regarding dilution are the a 
same asin SeriesI. All are set in Cooley cans in vat in cold Mi 
water, 1, 3 and 5 creaming twelve hours, and 2, 4 and 6 creaming ;: 
twenty-four hours. 
Series ITT. 
In the third series, the conditions regarding dilution are the if 
same as in preceding cases. 1,3 and 5 are set in Cooley cans 
in vat of cold water, while 2, 4 and 6 are set in shallow pans in 
. 4 _ open room, for thirty-six, hours. 
a | Series IV. i 
The conditions of dilution observed in preceding series are the a 
_ same in this series, All are set in open room, 1, 3 and 5 being in ip 
* Cooley cans, 2,4 and 6 being in shallow pans, for thirty-six hours. y 
In carrying on the experiments the following observations 
are made and recorded: (1) Pounds of milk set; (2) pounds 
of water added to milk; (3) temperature of water added; 
_ temperature of milk (4) before dilution; (5) after dilution, 
and (6) temperature when set; (7) depth of milk set; 
temperature of (8) water in Cooley vat and (9) of air in open 
om ; we) SC of cream ; time (11) when set, and re
