formed, the liquid in the dialyser was filtered. Even after 
repeated filtration the filtrate remained slightly milky, but 
when heated no increase in turbidity was perceptible, so that 
all the proteid in the extract had been precipitated by dialysis. 
Distilled water was used throughout. The dialysate was 
changed daily and tested, but there was no indication that 
any proteid had passed through the dialyser. 
In accordance with these facts, the table of the proteids of 
flour on p. 546 may be amended by the following addition : — 
I. Globulins : precipitated by C 0 2 , and by dialysis, from 
neutral saline solutions. 
Hence the correspondence between the globulins of germ 
and those of flour may be regarded as fairly complete.
