from tlie second teat l)cin.c[ the riclicst, and from the fourth the poorest. 

 " If, however, we take the avera<?e for each teat for the first four milk- 

 inus, independent of the order of milking, we (ind tliat so much of the 

 difference has disappeared that it is doubtful about there being auy 

 difference in the physiological functions of the different quarters of the 

 udder. * * * The average per cent of fat in the milk was much 

 h'ss than in milk from the same cow when milked in the ordinary way, 

 two teats at a time." Thus a cow giving milk containing 5 per cent 

 of fat gave, when milked one teat at a time, milk averaging for four 

 milkings 3.92 per cent of fat ; and in the case of another cow the milk, 

 usually containing 4 per cent of fat, fell to 2.7 and 3 per cent when 

 milked in this way. 



Milking fast and slow (pp. 47-50). — In tests in which cows were milked 

 in from three to four minutes and double that time, the yield of milk 

 seenuxl to be very little if any affected, but in every case richer milk 

 was produced when the cows were milked fast than when they were 

 milked slowly. This difference in quality, however, seemed to decrease 

 gradually', though not to disappear altogether. 



Change of milker, methods of milking, milking tubes vs. hand milking, 

 and change of quarters (pp. 5()-5G). — Tests made on these subjects seemed 

 to show that change of milker, manner of milking, and change of 

 environment all exert a more or less decided influence, temporarily at 

 least, on the quantity and quality of the milk produced, the fat being 

 as a general rule more sensitive to such changes than the other ingre- 

 dients or the total yield of milk. 



Effects of dehorning upon the composition of milk ([)p. 57-G2). — Ten 

 cows were cehorned in the evening just before milking. 



There was a very marked difference in the behavior of the different cows, some of 

 them being scarcely affected, while with others the effect was decided. With all the 

 cows that fell off either in yield or quality, there was at the next morning's milk- 

 ing an improvement, this being more marked in the per cent of fat than in the yield 

 of milk. In some cases this was sufficient to entirely obscure the immediate effect. 



The milk yield of other cows in the stable " was diminished almost 

 as nuich on the evening that the dehorning was done as was that of the 

 dehorned cows."
