If the day's labour be estimated at 10 hours, and converted, 

 as before, into work done in ft. lbs. per ounce, per minute, we 

 find- 

 Day Labourer = = 2.297 ft. lbs. per oz. per min. 



Collecting together into one Table the rates of Statical and 

 Dynamical work of muscles already described, we obtain —
