and studies, it follows that the quantity aud type, especially of the unorganized 

 ferments added with the rennet ; the condition of the in-oteid when the enzyms 

 are addetl ; the rate as well as the amount of acid development ; the condition 

 of the curd when weighting is done, and the extent to which in young cheeses 

 the organisms other than the lactic bacteria exceed the 3 : 97 proportion ; is 

 each able to cause physical and chemical divergencies, which divergencies, if 

 not obsei'ved and dealt with during the process of cheese manufacture, will 

 render unattainable the ideal i)ermanent characteristics assumed to be the 

 ultimate aim of the hard-cheese-maker's art."

 1, pp. 72, fig. 1 ) . — The report shows that 40 test associations, with 454 different

Milk records, J. Spier {Trans. Highland, and Agr. 8oc. Scot., 5. ser., 20 

 {1908), pp. 235-258). — Statistics are given regarding the yield in milk and 

 butter fat of 3,931 cows tested by 7 agricultural societies during the year 1907. 



The results discussed clearly indicate the immense improvement in milking 

 stock obtained by judicious breeding. It is also pointed out that " cows pro- 

 ducing a large quantity of milk of good quality do so at a much less cost for 

 food per gallon of milk than those yielding half the produce." 



Milk and butter tests at the Lincoln show, 1907, E. Mathews {Jour. Roy. 

 Agr. Soc. England, 68 {1907), pp. 138-152). — A considerable amount of statistics
