OBSERVATIONS BY HASSELBALCH. 15 



to be somewhat lower in winter than in summer. In the Bohemian 

 article we find a somewhat more extended discussion of his results, 

 inasmuch as Babak points out that the respiratory quotient does not 

 show regularity, this being largely due to variations in the carbon- 

 dioxide determinations. The majority of the low values for the 

 respiratory quotients were found during the low temperature of winter, 

 and Babak concludes that since similar observations were obtained 

 with rabbits he can corroborate the discovery of Scherer that in winter 

 assimilation is greater than disassimilation, or that anabolism is greater 

 than katabolism. 



OBSERVATIONS BY HASSELBALCH. 



In 1904 Hasselbalch, 1 publishing in a remote place, presented a most 

 interesting paper on respiration experiments with new-born infants. 

 At the time of going to press with our earlier publication, this Danish 

 contribution was in process of translation, and hence it was not then 

 cited by us. Upon the completion of the translation, for which it is 

 a pleasure to thank Miss Alice Johnson, of the Nutrition Laboratory 

 staff, and Dr. M. N. Smith-Petersen, of the Peter Bent Brigham 

 Hospital, we are so impressed with the accuracy of the technique and 

 the clear-cut conception of Hasselbalch' s conclusions that we feel it is 

 incumbent upon us to make this material available to readers in other 

 than Danish, and hence it is here reprinted. We wish to express our 

 thanks to Professor Hasselbalch for his kindness in looking over the 

 manuscript and making some slight alterations in the phraseology of 

 the translation.
