290 REPORTS ON THE STATE OF SCIENCE.—1912. 
It is clear, in the first place, thal the ‘ efficiency’ of these three 
different persons of different ages (45, 24, 36) and of quite different 
physical appearance and habits is almost the same, and in the second 
place that it is at least (see remarks above) of the magnitude of 24°6 
per cent. 
This method of proceeding by the consideration of increments of 
work is obviously preferable to the comparison of work and so-called 
‘ rest,’ and tends to eliminate the first difficulty described previously. 
In addition to these experiments, a large number of other experi- 
ments have been performed at different revolution rates, which when 
detailed will be found:to support the conclusion arrived at as to the 
‘ efficiency ’ of man as a machine. 
The Effect of Climate upon Health and Disease.—Report of the 
Committee, consisting of Sir LaupER Brunton (Chairman), 
Mr. J. Barcrort and Lieut.-Colonel Simpson (Secretaries), 
Colonel Sir D. Brucz, Dr. G. S. CAMPBELL, Sir KENDAL 
FRANKS, Professor J. G. McKenprick, Sir A. MITCHELL, 
Dr. Porter, Dr. J. L. Topp, Professor Sims WoopHEAD, and 
the Heads of the Tropical Schools of Liverpool, London, 
and Edinburgh. 
Tue Committee has been in treaty with the Royal Society of Medicine, 
which. has made certain alterations in its rules necessary for the 
co-option of the Committee with its Section of Balneology and Clima- 
tology. : 
‘The Committee does not ask for reappointment. 
The Dissociation of Oxy-Hemoglobin at High Altitudes.—Report 
of the Committee, consisting of Professor E. H. STARLING 
(Chairman), Mr. J. BaRCROFT (Secretary), and Mr. W. B. 
Harpy. 
Tue work of this Committee was practically completed, as it seemed, 
when they returned from Monte Rosa a year ago. The Committee then 
presented. an interim report accounting for the expenditure, except in 
so far.as the outlay for apparatus was concerned. As the account for 
this was still open, some of the. apparatus being under repair, it was 
necessary to defer this portion of the report. The amended statement 
of account is now presented. During the past year certain control 
experiments have been carried out which show that the value of the 
work carried out in the Alps can only be duly appraised when similar 
experiments have been carried out during ascents from the sea-level to 
1,000 feet. Carlingford Mountain offers an ascent of 1,000 feet which
