450 grams more than the first, Newman, who weighed 4.770 
kilos, and he was zVi cm. longer, but as the formula contains 
only one variable and that the weight, it gives a surface area 
for the second child less than for the first, though it is un- 
doubtedly greater. The formula is apparently very accurate for 
well-nourished infants but not for the long and poorly nourished. 
The heat directly determined and calculated for a square meter 
of body surface in twenty-four hours was in the two cases 994 
and 1,093 calories. These figures correspond closely with the cal- 
culated heat in three of Rubner's cases, viz., 1,006, 1,143 and 1,090. 
The average C0 2 per square meter per hour was: Newman, 
15.24; McG., 17.19.

Studies on human nephritis. 
By Y. S. MSARA and A. I. RINGER. 
[From the Department of Therapeutics of the Cornell University 
Medical College.] 
Preliminary Report. 
The object of this investigation was to determine the functional 
capacity of the kidneys of nephritics with regard to their power 
of eliminating nitrogenous material, water and salts, and to de- 
termine the influence of the ' ' protective therapy" on the kidney 
efficiency.
