The final result is d. 19.94-19.95, and A = 33.9. Niton.-For the atomic weight of niton, the gaseous emanation of radium, Gray and Ramsay' give

Miscellaneous Notes.-Hinrichs3 has reconsidered all the evidence relative to the atomic weight of hydrogen, and concludes that H = 1.00781. I n another paper4 he discusses the atomic weight of vanadium, which he places a t 51 precisely. A brief note by Ter Gazarian5 defends his work on the density of PH,. C. Henrys has considered the proper mode of calculating atomic weights. Relations between the atomic weights are studied by Loring,' by Emersons and by Nicholson.@ Emerson's "helix chimica" is an arrangement of the elements on while Nicholson develops a structural theory of their formation.
