In conclusion it may be said that according to present 

 knowledge a conscientious farmer or dairyman, anxious to 

 ensure the freedom of the milk which he supplies from 

 tubercle bacilli, cannot be expected to do more than see that it 

 is obtained with the greatest possible cleanliness, and that it is 

 derived solely from cows that present no indication of being 

 tuberculous either in the udder or elsewhere. It ought to l)e 

 added that he cannot be expected to do any less.

ANNUAL REPORT FOR 1911 OF THE 

 CONSULTING CHEMIST. 



There was, in 1911, a slight diminution in the number of 

 samples sent for analysis, this being 439 as against 480 in 1910. 



In addition to these, there were 226 samples of milk and 43 

 samples of cider and perry analysed in connection with the 

 Norwich Show of the Society. 



The detailed list of samples examined is given at the end of 

 this Report. 



The most marked feature of the year has been the rise in 

 the price of feeding materials. Linseed cake, for instance, has 

 gone up to 11/. per ton, or even over this, while undecorticated 

 cotton cake has seldom been below 6Z. per ton. The difference 

 of price between Egyptian and Bombay cotton cakes has been 

 very variable. As a rule, this has been about 10s. per ton, but 

 the prices of the two have not unfrequently approximated to 

 within 5.S. per ton of one another. 



Decorticated cotton cake has been scarce, and its price high, 

 namely, 8/. to 8/. 10s. per ton. 



Soya bean cake has hardly met with the increased demand 

 at one time expected of it. ' 



No new feeding material of any account has been introduced 

 to the market, except, possibly, " Bastol," a preparation of 

 treated wood pulp and molasses. 



As regards the i)revalence of adulteration, linseed and cotton 

 cakes have been found to l)e uniformly good and free from 

 adulteration. Occasionally "Bombay" cotton cake has been 

 sold for " Egyptian." In compound cakes, the tendency for a 

 high percentage of sand to occur continues.
