It was now determined to try the effect of a still more excessive load on the haunches; for which purpose the loads were removed from Nos. II, III, IV, V, vi, and VII, and the bolts which had hitherto confined the model to the abutting pieces were cut away, in order to ascertain whether there was any tendency to slide up or down the inclined planes which supported the soles as ik,

There appeared, however, no tendency to slide on the abutments, but the crown rose one-tenth of an inch. The weight was now five or six times greater than could occur in practice, while there was nothing at the crown to represent the weight of the centre itself, and of the planking, bracing, and other extraneous matters. The first applied weights of 714lbs. and 740 lbs. produced, as before stated, no effect.

The loads were afterwards increased till they were as follows:

:

No alarming symptoms of distress were exhibited, and the model remained uninjured. The index had been accidentally deranged during the application of these last weights, and of consequence the greatest depression was never ascertained.
