As stated in the preface, this is a laboratory manual especially designed for the particular circumstances at the University of Glasgow; therefore the book offers little attraction for those working under other conditions. Only sixteen laboratory periods are offered; the first six and a part of the seventh are experiments on the frog. Approximately the same amount of time is devoted to experiments on special senses on human subjects. The remainder of the time its devoted to laboratory experiments on circulation and respiration and to observations on human subjects. All the experimental procedures are the conventional ones, such as are found in any laboratory manual. No attention is given to digestion, metabolism, endocrines, kidney, or the lymphatic system.
