Excerpt from The Gaseous Metabolism of Infants: With Special Reference to Its Relation to Pulse-Rate and Muscular ActivityMensi' of Turin, without stating the apparatus employed or even the fundamental principle, reports a series of observations on 5 new-bom infants varying in age from 6 hours and 5 minutes to 7 days, 17 hours, and 54 minutes. In these experiments the oxygen consumption was determined as well as the carbon-dioxide production. The results are given in table 3. The statement is made that the infants were quiet in each case, but no pulse records are given.Table 3.-summary of experiments on respiratory exchange of new-born infants (mensi).A very interesting series of experiments on infants was carried out by Scherer, 'in the institute of Professor Mares in Prague, ' with an apparatus on the regnault-reiset principle, the oxygen being supplied from a bomb. The author states that the infants found themselves in complete physiological conditions inside the chamber. In this series, 55 experiments were made in the spring and summer and 30 experiments in the winter, each one being about 2 hours long. No information 13 given regarding the activity of the infants or the pulse rate. The fact that the average respiratory quotients were consider ably below points strongly to an error in the method. The author concludes that the intensity of the respiratory exchange is dependent upon the body-weight and is inversely proportional to it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
