Abstract

My basal metabolism was first examined in Zuntz's laboratory in 1891 at the age of 26 years. When I was 76 I had the opportunity of having it reexamined by Dr. Walter A. Boothby when I was at the Mayo Clinic in 1941 to give a lecture. During the interval, no measurements were made. Although the figures reveal nothing new, it might be of interest to publish them since they are unique.

The decline of basal metabolism with advancing age, established by Falk and Magnus-Levy,1 has been subsequently confirmed by a number of workers. Du Bois2 quotes values of 39.5 calories per square meter per hour at 20 to 30 years and 35.5 calories per square meter per hour at 70 to 76 years, a decrease of 10 per cent.

My record is given in table 1.

The values for surface area are based on Du Bois's formula.
