Excerpt from Twenty-Second Annual Report of the Secretary of the Massachusetts Board of Agriculture: With an Appendix Containing Reports of Delegates Appointed to Visit the County Exhibitions, and Also Returns of the Finances of the Agricultural Societies, for 1874 In the secretions of the salivary glands there is a ferment which dissolves albuminoids and changes sugar into an acid, and these effects may be carried on after the secretions have been separated from the body of the animal, and can be con tinned from parcel to parcel of matter, as in any other case of fermentation. In my investigations of rennet, I found the active agent to consist of minute germs, which proved to be the spores of blue mould. I watched them through their changes till they threw out filaments of mould, and multiplied by seed-balls on the ends of those filaments. The action in rennet is that of a ferment or true yeast, and may be contin ued indefinitely from one batch to another. The changes which occur in the kidneys and bladder appear to be of the same nature. I have found germs in the bladder analogous to those in the stomach, and used them to carry on a continued series of changes after they had been separated from that organ. And lately the action of the pancreas in converting chyme into chyle has been proved to be the action of a ferment or yeast. The germs are now separated from the secretions of those glands, and used as a remedial agent, the secretions, after the removal of the germs, being entirely inert. From their close resemblance to the rennet germs, they are supposed to have a similar origin. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
