Popis: In pursuance of the investigation of dock labour initiated for the Food (War) Committee of the Royal Society last year, and thanks to the courtesy of several officials of the Port of London Authority and of several willing labourers, we were able to make two series of hourly observations of the CO 2 output of four labourers engaged upon heavy work in cold storage. A first short series was made during December, 1918, at the East Surrey Docks; a second and longer series at the Charterhouse Cold Storage Chambers, Smithfield Market during July, 1919. The data we have been able to obtain are obviously scanty, but, we believe, sufficient to prove the possibility of acquiring valuable information by an expeditious method, applied during normal work, and involving a minimum interference with that work. Our attempt to submit such scanty results to statistical treatment may perhaps be regarded as premature; we have, however, found it convenient, if only for the purpose of bringing out the necessity of more extensive observations, to work out the standard deviation and the ± probable error in the arithmetic means of the two series of observations made under different conditions.
