Niger-cake, it will be seen, is poor in oil ; and contains much 
woody fibre, but gives as high a percentage of albuminous com- 
pounds as occurs in genuine linseed-cake. It is largely used for 
adulterating the latter.

white mustard ; it is a flat, cordate-shaped 
seed, and either light or dark coloured.

Sesame-cake is rich in albuminous compounds, and contains 
as much oil as good linseed-cake. 
Teel-oil is much used both for cooking purposes and burning 
in Egypt, India, China, and Japan, and may be kept for many 
years without becoming rancid. The press-cake, usually retain-
