Crowe, L. K. & Davis, H. P. (1927). Babcock testing --- principles and uses (University of Nebraska Agricultural Experiment Station Circular No. 35)
The manufacturing of dairy products on a commercial scale began about the middle of the nineteenth century and was greatly stimulated by the development of the centrifugal cream separator in the late eighties. The invention of the Babcock test in the early nineties overcame some of the difficulties that had developed in paying for milk upon its butterfat content, since it was early recognized that milk varied widely in that respect.
