Experiment, No. 2. 
Distance of the Props, 31 feet 6 inches; the same specimen of wire as in Experiment, No. 1, 
but had not been before used ; the two ends of the wire in this Experiment were fixed, after 
drawing it as tight as possible; viz. to within less than one-eighth of an inch of a horizontal 
line, and the weights applied only in the centre.
