After studying the systems: Barium halide‐urea‐water and strontium halide‐urea‐water (loc. cit.), it was of interest to extend the investigations to calcium halides, to discover the analogous and other complex compounds, if any, more in solution. The measurements of conductivity and viscosity of the mixed solutions of calcium chloride‐urea, calcium bromide‐urea and calcium iodide‐urea, indicated the existence of five definite complexes in solution, the formulae of the compounds are: (1) CaX 2 · CO(NH 2 ) 2 , (2) CaX 2 · 2 CO(NH 2 ) 2 , (3) CaX 2 · 3 CO(NH 2 ) 2 , (4) CaX 2 · 4 CO(NH 2 ) 2 and (5) CaX 2 · 6 CO(NH 2 ) 2 .
