He cites several experiments by other investigators, using rats and dogs in which the brachial plexus had been severed. Shortening of bone and atrophy occurred in all the experimental animals, to varied degrees. Armstrong's own experiment on large rats, also performed after the brachial plexus had been severed, indicated that (1) the growth in length of the radius was affected earlier, and to a greater degree, than that of the humerus; (2) the reduction of growth in diameter of the humerus was greater than the reduction of growth in length; (3) the growth in diameter . . .
