Experiments on the preparation of homemade rennet, A. Todd and Elfrida 

 C. V. CoKKisH {Jour. Bd. Agr. [London], 23 (1916), No. 6, pp. 549-555).— Ex- 

 periments are reported on the home preparation of rennet from both fresh and 

 dried stomach membranes of calves. 



Rennet prepared from dried veils was of no practical value. Fresh veils 

 of from 3 to 4 months-old calves and from young milk-fed calves produced an 

 extract with fairly strong coagulating properties. With the addition of a 

 preservative the rennet kept in good condition for six weeks and was then still 

 active. The method of making the rennet is described. When used for cheese 

 making in about double the quantity of commercial extract this rennet gave a 

 very firm curd in a reasonable time.

 system of selling cheese are pointed out, and a description is given of the 

 Quebec system of inspection and classification of cheese before sale. The 

 author states that by this system, which is used by the Quebec Cooperative 

 Society, many of the objections to the cheese board have been overcome.
