then dissolved in warm water, from which, on cooling, long curled light- 
yellow needles separated. The fusing point of this compound after 
repeated re-crystallizations remained constant at 187°C. When solutions 
of the compound in water are boiled hard aniline separates out. An analy- 
sis of the substance indicated it to be a union of one mol. chlordinitro- 
phenol with a like amount of aniline—C, H, Cl (NO,), CH. C, H; NH,. 
Analysis.—.1221 grms dried substance burned with lead chromate gave 
.0188 grms. Carbon = 46.19% C. The hydrogen determination was lost. 
The theoretical percentage of carbon demanded by the above compound is 
46.22 ZC. 
With the ammonia-cobalt bases of Genth and Gibbs, a-Monochlordinitro- 
phenol yields exceedingly beautiful compounds. My results in this direc- 
tion will be given later. 
BERYLLIUM BORATE. 
Some time ago I was working with beryllium and added to a solution of 
its chloride an excess of a rather concentrated borax solution. An imme- 
diate precipitation was the result. The precipitate was thrown upon a fil- 
ter and washed with hot water, until a drop of the washings evaporated 
upon platinum foil left no residue. 
The precipitate was dried and tested for boracic acid, but this was not 
found present. Another portion of the same precipitate subjected to an 
analysis proved it to be nothing more than beryllium hydrate, consequently 
if the borate had been at first produced, the subsequent boiling with hot 
water had decomposed it. 
Another portion of the beryllium chloride was treated in a similar man- 
ner. The precipitate was brought on the filter to allow the liquid to drain 
off, and then rinsed with cold water into a small flask, water added, and 
allowed to stand for some time—being occasionally shaken. The precipi- 
tate was then brought on to a filter and dried by exposure to the air. 
Boracic acid was found present when the tests were made. 
Analysis gave me the following percentages of beryllium oxide: 6.98 
BeO and 6.89 % BeO. 
The boracic acid was not estimated.
