Excerpt from book: Absolute figures for each group for the whole period of five weeks. Group: Per cent of acid colonies Corn : 33 of all colonies on plates, Wheat: 28 of all colonies on plates, Oats : 31 of all colonies on plates, Mixed: feed: 23 of all colonies on plates A final comparison of the por cent of acid colonies developing upon the plates showed practically no difference between the groups, in so far as the number of acid colonies ware concerned. These averages having been made from sets of results which vary in some instances from ten to forty-five per cent they can only be taken as roughly approximate. The nature of a part of the organisms forming these acid colonies can only be taken as a suggestion of what role fecal organisms may play in the different animals. This will be taken up subsequently. The Relation of Liquefying Organisms to the Feeds from the Quantitative standpoint - The data for this, part of the work was procured from the gelatin plates. Just as soon as colonies were observed to be liquefying the medium a count was made. In some instances the number. of liquefying colonies was so great as to make the total quantitative count of doubtful value. Such instances are noted by an interrogation point in the tables or the space left blank. Number Of Liquefying Colonies From Corn Fed Animals.
