euse for presenting the paper before the 
work was completed. Having made these 
observations quite four years ago, in the 
interim he has been engaged in securing 
direct from monazite sufficient quantity of 
pure thorium salts. Five thousand liters 
of solution have been worked up. The 
author’s supply of the element has been 
much augmented through the kindness 
of Dr. Waldron Shopleigh, of the Wels- 
bach Light Company, who presented him 
with two kilograms of his purest tho- 
rium oxalate. Last fall the author 
wrote Professor Bohnslar Brauner, of 
Prague, who had made the most recent 
atomic weight determinations of thorium, 
about his experiments. Not hearing from 
Dr. Brauner, the author was surprised 
to see in the Proceedings of the London 
Chemical Society, April 10, 1901, an article 
on ‘ Contributions to the Chemistry of Tho- 
rium’ by Dr. Brauner, in which he states 
that he had fractioned thorium by hydroly- 
sis of the oxalate into two bodies which he 
terms The and Th’. Brauner’s work as 
reported was by no means complete. While 
the author insists that he holds the very 
highest opinion of Professor Brauner, and 
while neither his work nor the motives 
prompting Professor Brauner in making 
this preliminary publication are called into 
question, in justice of the author’s work 
along these lines, it was not deemed un- 
scientific to present the results of incom- 
plete observations.
