Fuch )f Carlsruhe, Germany', was one of the first persons to suggest the utiliza- tion of centrifugal force to separate whole milk into cream and skimmed-milk. mately four years later, in 1S()4, Albert Fcsca ^ of Berlin and Antonin Prandtl ^ of ^Munich made studies similar to those of Fuchs. Bond, wliose work is mentioned above, made his studies in 1870. One of the first pieces of apparatus employed in sep- arating cream is shown in Fig. 17. These were intermittent methods. 43. Continuous separation.—The intermittent method was slow and wearisome. Therefore, in 1874, the idea of continuous sei)aration was concei\'ed. It is said ' MoKay, G.
