    striction of the total amount of food ingested, an observation that is of the greatest importance in inter- preting the reduction of obesity that follows the restriction of liquids. In nearly all of the cases the loss of weight, the quantity, the specific gravity and the appearance of the urine, as well as the concentration of the blood, showed that a condition of thirst really existed. The withdrawal of liquids was in no case carried to excess, if for no other reason than the one that such extreme reductions in the fluid-intake are not employed in prac- tice in reduction cures for obesity. The determination of the interchange of gases was performed with the Zuntz-Geppert apparatus, an ap- paratus that has already aided us in discovering so many truths in regard to the physiology and the pathology of the gas-metabolism of the organism. The short duration of each experiment (20-45 utes), it is true, rendered it necessary to e.xercise con- siderable care in interpreting the results obtained; the great facility, however, with which a large number of single determinations that controlled and supplemented each other could be performed in the same individual fully compensated for this defect. All the g^s-figures were reduced to 0°, 760 mm, barometric pressure, and dryness. The determinations of the specific gravity of the blood were performed with the pyknometer and were always made at ii a. m. In order not to extend and complicate the tables too
