This was taken as theunit of strength. Other triangular musclesof different weights, operating in dissimilartriangles, could be accurately estimated as totheir comparative strength. The rule which I followed was that laid down by Haugh-ton (see Haughtons Principles of Animal Mechanics, p. 1S3), from which I quote: The work done by the same (a triangular) muscle will be proportional to doublethe perpendicular, let fall upon the side of a triangle from the foot of the bisector of thevertical angle. The quality of the muscular fibres of each group very closely cor*. 142 respond. In each group are found fine or coarse muscular fibre in about the same pro-portion. The rule applied to ascertain the relative strength of the great adductor andabductor group gives to the adductor group a decided advantage, because they standparalel with the plane of the triangle, whereas the glutei muscles do not, but were so measured and estimated. In spiteof this advantage given in theestimates the abductor group actingon the shorter lever was found tobe much stronger than the adduc-tors, the proportion being onehundred and thirty-one pounds tothe abductors, to one hundred andsixteen pounds to the adductors inthe subject examined. Then, whenall the muscles are affected byspasm equally and the limbs parallel,the abductors would produce ab-duction because of their superiorstrength. From our clinical observations/ at once concluded that the reasonwhy the limb went over to the de-formity of the third stage of th
