Excerpt from The Journal of Experimental Zoölogy, 1907, Vol. 4 G. Bohn, 21 who studied the effects of radium rays on the eggs and larva of the frog and turtle, found that if growth is slow exposure to radium rays prevents the attainment of full size if rapid and associated with tissue differentiation, radium causes degenera tion Of the tissues and although at first accelerating, ultimately stops development. He considers that everything leads one to think that the rays of radium affect the chromatine because it is from the activity Of this substance that there results assimilation and growth.
