The triceps and biceps are sometimes PSEUDO-HYPERTEOPHIO MUSCULAR PARALYSIS. 509 enlarged, the former more frequently than the latter, but occasionallyonly in one part. Both these muscles are sometimes wasted. The forearm muscles suffer inonly a tmall minority ofthe cases, and the intrinsicmuscles of the hand usuallyescape altogether. This escape of the intrinsic muscles of the hand affords a very marked contrast to spinal muscular atrophy, in ^™^... which they suffer early; but.
