Abstract
WITH reference to the paragraph on the method of maceration by tryptic digestion in NATURE of March 6, p. 9, it may be of interest to your readers to learn that further work on the process has shown that equally good results are obtained by the use of Messrs. Allen and Hanbury's Liquor Trypsini Co. This costs only 3s. 9d. a bottle, and the requisite strength is obtained by adding 1 c.c. to a litre of water. The procedure is in other respects identical with that previously described. The trouble of dissolving the powder is thus avoided, and the cost is reduced from is. per litre to rather less than ½d., so that the method becomes practicable for use on a large scale.
