affected. On the whole, the milk on Sunday afternoons was 

 richer, because of the shorter interval between the milkings 

 on that day, and Monday morning's milk was poorer for the 

 opposite reason. 



The milk of a small red shorthorn cow (No. X) was tested 

 from the beginning of May till the end of October. She 

 calved (her third calf) on May 3rd. This cow is also quiet and 

 good tempered. She was out at night from June 4th till 

 October 8th. She received 6 Ib to 8 Ib cake and meal daily 

 during the whole period, and was milked as follows : May 

 and June, 8 a.m. and 6 p.m. ; July and August, 7 a.m. and 

 6 p.m. ; September and October, 7'30 a.m. and 5 p.m. ; but 

 on Sundays during the whole period, 8 a.m. and 4 p.m. 



During one hundred and sixty-five days the solids not fat 

 were fifty-eight times under the 8'5 per cent, standard in the 

 morning, and fifty-seven times in the evening. These were 

 higher during September and October, but lower and more 

 variable during June, July, and August. The limits of 

 variations in solids not fat were : In morning, 7'08 per cent. 

 on July 2nd and 9*83 per cent, on October 10th; in evening, 

 7'00 per cent, on July 1st and 9'52 per cent, on October 9th. 

 During the same time the fat was thirty-five times under 

 the 3 per cent, standard in the morning and twenty times in 

 the evening. This cow has very frequently had less fat in her 

 milk in the evening than in the morning, and had less fat on 

 the average during July than during the other months. 



The fat in the evening's milk was very low after the hot 

 day on July 1st and after the thunderstorm on July 2nd. 

 Great and sudden variations occurred throughout the whole 

 period. Cold nights occurred in June, at which time the 

 morning milk was usually much poorer than that of the 

 evening, but during the fine days in July the reverse was 

 usually the case. This cow gave about 4 gallons a day for 

 the first three months, but less during August, about 3 gallons 

 a day during September, and about 2 gallons a day during
