Compounds of Selenium [PDF]

Nature, 1890
IN your issue of the 23rd ult. (p. 284) you insert a paragraph describing experiments by M. Chabrie on compounds of selenium. While fully acknowledging the value of his work on the phenyl derivatives of selenium, I think it right to state that much of M. Chabrie's investigation has been anticipated by Mr. F. P. Evans and myself as long ago as 1884; and
