TliG '■ Metaholic Balance Sheet' of the Individual, Tissues. — Final lie jiort 

 of the Committee, consisting of Professor Gotch (Chairman), Mr. 

 J. Bakcroft {Secretary), Professor E. H. Starling, and Professor 

 T. G. Brodie. 



The Committee appointed in 1903 have since that time lost one of their 

 members — Sir Michael Foster, K.C.B.— in whose place Professor Brodie 

 Avas appointed in 1907. 



The Committee had for their object the development of what seemed 

 likely to be a fruitful field of physiological inquiry. It was -recognised 

 from the first that the experimental difficulties would be considerable, and 

 it was therefore thought desirable to ensure the co-operation of a number 

 of investigators who were especially well qualided for the study of some 

 particular tissue problem. 



The work which the Committee might with advantage undertake in 

 connection with tissue metabolism ranges over an extremely large field, 

 and, bearing this in mind, the Committee determined that their first duty 

 was to lay the foundation for future work by the development of sound 

 and fruitful methods, utilising for the purpose a limited number of tissues. 

 This object has been now more or less obtained, and the Committee do 

 not therefore propose to ask for reappointment. They recognise that 

 there is need for further special research as to the metabolism of special 

 tissues, but they consider that this may now be left to individual effort, 

 aided by grants for specific purposes. 



In presenting their final report it seems desirable to review some of 

 the work which has been cari'ied out during the last five years, and which 

 has been rendered possible by the financial help afforded by the grants 

 given to the Committee by the Association,

Apparatus. — The essential observations in an experiment on the 

 o-aseous exchange of an organ are three in number — the analysis of 

 arterial blood, the analysis of the venous blood whicli comes from the 

 organ, and the rate of flow of blood through it.
