that a large number of such indefinite compounds might 
be prepared by slightly varying the conditions. 
Nylander (Bidrag till kinnedomen om Zirkonjord Inang. 
Diss. Lund 1864.) madea series of attempts at dehydra- 
ting thechloride. He prepared the chloride by dissolving 
the hydroxide in hydrochloric acid and evaporating to crys- 
tallization. The salt formed white needles, easily soluble 
in water. They were washed with alcohol and for analy- 
ses I and II were pressed between filter paper; II and 
IV were dried over sulphuric acid. The results were as 
follows:

Again preparations were made as before. I was dried 
between filter paper, II over sulphuric acid, III was 
pressed between filter paper and then dried over sulphu- 
ric acid, IV was dried a long time over sulphuric acid. 
The analyses gave the following:

Lastly he allowed a solution of the chloride to evaporate | 
over sulphuric acid washed the crystals obtained with 
alcohol and pressed them between filter paper. Analyses
