ARACHIS HYPOG.EA (pEA-NUT) 



57 



The amount of oil present in the seeds varies not only 

 according to the varieties, but with the climate as well. This 

 variation is difficult to explain, and we must be content 

 merely to state that the proportion of fatty matter is higher 

 or lower, according to the more or less favourable con- 

 ditions of growth and distribution of rainfall. It has been 

 remarked that, even in the same district and with a similar 

 variety, the fatty matter varies from year to year. 



We give below the average composition of the pea-nuts 

 of various countries. 



Ordinary Commercial Pea-nuts — Matter devoid of Moisture. 



' The figures in the first si.x columns are taken from " L'Arachide'' of J. Adam. 



It will be noticed that the oil content is everywhere about 

 the same, except in Japan. 



In reducing these figures to terms of the whole pod the 

 gross proportion of oil may be ascertained : — 



Senegal 



United States 



Egypt 



Congo 



Bombay 



Spain 



Mauritius 



Among the varieties tested at the Agronomic Station 

 there is also no appreciable difference between the various 

 proportions of fatty matters. The following analyses were 

 published in the annual report for 1910 : —
