TbeHe experiments include all which were carried on up to the close of tho.se witli man tabulated beyond, with the exception of one or two which were ko vitiated by accident as not to be completed. The first of the tests reported was made the latter part of Ai)ril, 1807, immediately before metabolism experiment No. 5. Immediately pre<e<ling experiment No. <J a second alcohol test was made, and pre- ceding No. 7 the third test was carried on. This ended the experiment- ing until the fall of 1897, when test No. 4 was made. The determinations of carbon dioxid and water in this latter test were not satisfactory, and a fifth test wa.s made, in whi(;h the agreement of the determinations of carbon dioxi<l, water, and heat actually measured, with the theo- retical quantities prochuMjd by the combustion of the alcohol, was very satisfactory. Metabolism experiment No, 8 immediately followed this
