A theory has been long advocated that the ultimate spheroids of milk or cream were hollow and contained butter, and this of late has given rise to a variety of churning implements under the name of " Milk-Grinders," the inventors claiming that, by their peculiar mode of manipulation, these molecules or spheroids were more perfectly broken, and therefore that they could liberate the butter in five minutes, or even less time. They, however, churn with the milk or cream at very high temperatures

They, however, churn with the milk or cream at very high temperatures, producing less butter, without grain, being homogeneous in its character, and not possessing good keeping properties. By close microscopic in- vestigation we have failed to find these spheroids, and therefore do not believe in their Fig. 220. Lapham & Wilson's Air Pressure Churn. The requirements for a good churn are the ability to produce butter from sweet milk or cream, at a low temperature, possessing perfect grain and good keeping properties; ten minutes is as short a time for the production of such,as has been.
