Under the supervision of Dr. Francis G. Benedict, director of the Carnegie Nutrition Laboratories in Boston, Mr. Levanzin of Malta fasted for thirty-one days. The full report of the extensive observations made on him during this experience will appear shortly as a Carnegie publication. I am deeply indebted to Dr. Benedict for his permission to make this preliminary report on the blood which I examined. The report includes a somewhat curtailed analysis of the literature and the bibliography is limited to the references quoted. The details of technic and the correlations with the other findings are omitted.
The blood has frequently been studied during inanition, but an exhaustive search through the literature brought to light only a few records of systematic examinations covering so long a period of fasting in man as the case that forms the basis of this report. More or less authenic accounts
