4. Nut Oil.—In seven months it absorbed but 3c. c.: in six 
weeks following, it increased to 7 c. c.; in the next week it sudden- 
ly absorbed 27 c. c. per day, under a temperature of 73° F, _ It ab- 
sorbed in the whole 578 c.c. of oxygen, and was almost « entirely 
discolored by the operation, and was reduced to so gelatinous a con- 
dition as not to stain paper. 
It thus appears that the drying oils form less carbonic acid ‘than 
the. non-siccative oils ;—olive and almond produce one volume of 
acid gas, for the fourth or fifth of the oxygen absorbed,—and the 
nut and hemp, one volume for the seventh of the oxygen.
