These experiments include all which were carried on up to the close of those with man tabulated beyond, with the exception of one or two whi(;h were so vitiated by accident as not to be completed. The first of the tests reported was made the latter part of April, 1897, immediately before metabolism experiment No. 5. Immediately preceding experiment No. G 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 carljon dioxid and water in this latter test were not satisfactory, and a fifth test was made, in which the agreement of the determinations of carbon dioxid, water, and heat actually measured, with the theo- retical quantities produced by the combustion of the alcohol, was very satisfactory.
