(5) The author has determined the tensile strengths of the 
hairs of the various qualities of cotton by means of the apparatus 
described in the previous abstract, and has given, in a series of 
tables, the breaking weights in grain of every hair tested, with re-

ought not to be taken apart from the detailed tables, where the 
particulars of the breaking of about twenty hairs of each kind of 
cotton are given :
