In this memoir are described the results of a complete investigation of the crystals of the potassium, rubidium, cæsium, and ammonium salts of the iron group of double selenates of the monoclinic series R2 M (S Se O4 )2 , 6H2 O. It has been rendered possible by the success which has at length attended the author’s prolonged attempts to prepare ferrous selenate, and especially potassium ferrous selenate, as described in the preceding communication. The outstanding result is to confirm in every particular the conclusions drawn from the previous study of three other groups of double selenates (those containing zinc, magnesium, and nickel, as the M-metals), and of the complete set of eight groups of the double sulphates of this grand series.
