Abstract
IN connection with the suggestive letter of Sir William Ramsay and Mr. Cooke, the following observation appears to be of some interest. My friend Prof. H. H. Dixon, in conjunction with Dr. Wigham, in the course of some experiments on the β and γ radiations of radium on bacteria used a platinum rod to cast a shadow on the culture, in order the better to estimate by contrast whether the rays had effected the culture or not. The platinum rod so used to intercept the rays was of cylindrical form and about 3 mm. in diameter. Prof. Dixon's and Dr. Wigham's observations are published in the Proc. R.D.S., and also in NATURE.
