fat; (2) following a single injection (intraperitoneal, in mineral oil) 

 the heat production rises as the narcosis wears off, independently 

 of muscular motions, but parallel to the percentage of fat in the 

 blood. The following experiment illustrates the point.

This relationship as regards depth of narcosis and percentage 

 of fat in the blood has been confirmed with morphine. With 

 ether a second narcosis had the effect of raising the blood fat to a 

 higher point than the first. 



Blood fat has been determined by the nephelometric method 

 and heat production by indirect calorimetry.
