Here, also, the theory of GeneralMorris, which has been advanced as anexcellent criterion to judge of the regu-larity of the axes, is evidently defective. The knowledge of the fact thatthe vertical line ab divides the hu-merus as well as the distance rt intotwo equal parts already constitutesa factor which simplifies the appre-ciation of the mode of equilibriumof the fore part of the body ; forinstead of lowering, from the points e and g or /• and /, two pcrpendic.

Now that we have established the rational principles which indicatethe location of the axes of the anterior members, Ave can formulatefrom them practical rules in the following manner.
