Hence, extension is only perfectwhen the limb is made equal to its fellow, andthis can be easily known, he states, by the ex-amination of the tendo-patellae. Still another point (and one which I haje al-ready alluded to), is the relation of the fascialata to the act of standing at rest. The portionthat forms a sheath for the muscles of locomo-tion is, when we stand erect, or walk, drawntense by two muscles, the tensor vaginae femorisand the gluteus maximus

This tense condi-tion depends, of course, upon the integrity ofthe femur. The latter broken, there would nolonger be the resistance to the action of thesemuscles, and hence the unequal degree of ten-sion of the fascia lata in the broken and soundlimbs. The standing posture is the only one in whichthis can be verified, as in the reclining themuscles that make tense the fascia lata are bothrelaxed. April 7, 1877.] Communications. 307. The dotted line indicates the course of this stripof the fascia lata that has been alluded to. In theleft leg it is tense. In the right, the hands showwhere it will be most lax, in ca^e of fracture. In regard to measurements, I have only to addto what has been so often said, that every pre-caution should be taken to guard against can only be done by measuring from dif-ferent points, as the anterior superior spine ofthe ilium, the symphisis pubis, the point of thecoccyx, etc. Unless such a precaution is taken,a serious mistake may be made. Permit mehere briefly to illustrate this point. A man wasbrought to the Presbyterian Hospital, withsymptoms of dislocation of the right hip, whichdisappeared with appropriate manipulation, ac-companied by the audible sound. Nearly a yearlater he returned, with an apparent shorteningof the same limb, of about two inches. Uponthe most careful measurement from the anteriorsuperior spine of the ilium to th
