The results are of value in showing the possible changes in the urinary 

 elimination of chlorides, nitrogen, and total sulphur in very short 

 periods under normal conditions, also the effect of 2.75 per cent alcohol 

 upon the excretion of these substances. The investigation is being 

 continued. The analyses were made by Mr. W. M. Konikov, assisted 

 by Mrs. H. Konikov. 



Comparison of basal-metabolism apparatus. — Continuing his extensive 

 series of comparison tests, Dr. Carpenter made several comparisons 

 between the portable respiration apparatus, the gasometer method of 

 determining respiratory exchange, and the Jones metabolimeter, with 

 reference to the accuracy of the oxygen-absorption measurements 

 by these methods. 



The effect of alcoholic beverages containing 2.75 per cent alcohol by 

 weight. — In continuation of the work interrupted by Dr. Miles's 

 foreign trip in 1920, a further series of experiments has been made 

 on the subject who served previously, to find whether these later 

 results would confirm those already obtained, or whether there was a 

 measurable influence from practice and tolerance, and also to compare 

 the effect of different beverages. Afterwards the same routine was 

 carried out with five young men during a 6-day series of experimental 

 sessions. On the first two days alcohol was taken, but these tests 

 were only for practice. Of the last four days, two were normal and two 

 alcohol days. In all the experiments urine samples were collected, 

 usually at 30-minute and occasionally at 15-minute intervals; these 

 were later analyzed for alcohol concentration by the Widmark-Nicloux 

 method. Dr. Miles was assisted in the neuro-muscular tests by Mr. 

 E. S. Mills and in the chemical analyses by Miss Jane L. Finn, Mr. 

 W. M. Konikov, and Miss E. L. Frutkoff. 



Comparison of the percentage of alcohol in venous blood and in urine. — 

 But little literature has appeared with regard to the relationships 

 between the percentages of alcohol in venous blood and in urine. In 

 connection with several of the observations on the effect of alcohol, 

 Dr. Miles has made determinations of the alcohol present in both 

 fluids. Usually four blood-samples were taken from arm veins within 

 2 hours after alcohol was taken. Urine was passed about every 15 

 minutes and certain of the urine samples were coincident with the blood 

 samples. Dr. Howard F. Root assisted Dr. Miles in taking the samples, 

 and the analyses were made with the assistance of Miss E. L. Frutkoff 

 and with the help and criticism of Dr. T. M. Carpenter and Mr. 

 W. M. Konikov. 



The physiological and psychological fitness of diabetic patients. — The 

 emphasis by Professor Georges Dreyer, of Oxford, on the use of 

 four measurements, i. e., weight, chest-girth, sitting-height, and vital 

 capacity, as indices of physical fitness has led to the adoption of these 

 measurements by Dr. Root and Dr. Miles in determining the physical
