II . — On the Measure of Labour in India. 
To the Editor of Gleanings in Science. 
Sir, 
A correspondent, Cl, in the 4th Number of your Journal, has described a method 
of baling water very much practised iu India, and so simple as to be well entitled to 
the name ol primitive. He does not however allow it to be an effectual or profit- 
able mode of raising water, nor to bear any competition with the more complicated 
means of the Europeans. 
The result of his estimate is indeed very disadvantageous, when he compares “ six 
average Bengalees with one feeble old Englishman but I hope to convince him 
from the data furnished by himself that this comparison is fallacious. 
The amount of any force exerted, or of any work performed, is most convenient- 
ly measured and expressed bv the weight equivalent to the resistance overcome, 
multiplied by the velocity, and by the time during which the action continues ; or, 
assuming the time to be a day, the work may be designated by the weight raised to 
a given height ; in which form as only one term is variable, the comparative results 
of different kinds of labour, can be readily classed and appreciated. 
There is a marked difference, however, necessary in calculating the working effect 
of any self-acting machinery, and of animal or human labour : which is, that in the 
latter, the element of fatigue must be taken into consideration, and such intervals
