Abstract
FILTERED human serum gradually becomes turbid, through the formation of a precipitate which is mainly lipoid. The presence of approximately 7 gm. of lipoid in 1 litre of human serum is shown by shaking with a mixture of ether and alcohol1, when the protein is precipitated and the lipoid goes into solution. When ether alone is used, the protein is not precipitated, and negligible amounts of lipoid are contained in the ether extract. It has not hitherto been believed possible to remove lipoids in any quantity from serum by the use of ether alone.
