After pouring off the supernatant liquid the crystalline mass was pressed 
well between filter paper and then dissolved in alcohol. From this solu- 
tion the compound crystallized in beautiful, colorless, quadratic plates, 
which after several recrystallizations fused at 102° C. 
- Properties. Ifa crystal is fused upon a piece of glass it will remain in a 
plastic condition for hours and stirring it with the point of a knife blade 
will not cause solidification. One crystal which I fused required twelve 
hours before becoming solid. The fusing point of this solidified mass was 
the same as that of the crystals, 102° C. 
The compound may be volatilized without suffering decomposition. 
When pure it possesses a very peculiar, aromatic odor, somewhat like that 
of the preceding compound, being only more piercing. 
The compound is perfectly insoluble in water, but very readily soluble 
in chloroform. The best solvent I found to be alcohol, in which, when 
warm, it is exceedingly soluble. 
The following analyses were made : 
Chlorine Determination. 
0.4180 Grm. substance dried over calcium chloride and burned with 
oxide of lime gave 1.3146 Grm. silver chloride = .3252 Grm. chlorine 
= 77.79% chlorine. 
Carbon Determination. 
.9812 Grm. air dried substance burned with lead chromate, gave 21.69 % 
carbon and 1.00% hydrogen. 
If we suppose that only one hydrogen atom has replaced chlorine, the 
following numbers would be required : 
Calculated. Found. 
Cz = 22.09% 21.69% 
Cl,, = 77.81 % 17.719 % 
H = 0.09% 1.0% 
The formula would, therefore, be C,, Cl,, H. That the replacement would 
be so very limited, one would naturally suppose if he considered the pres- 
ence of such a large number of negative chlorine atoms.

Action oF Sopium AMALGAM UPON C,, Cl,, H. 
The substance was finally divided and dissolved in an excess of alcohol, 
and sodium amalgam added to the solution. The liberation of hydrogen 
gas was at first very violent, finally, however, the application of heat upon 
a sand bath was necessary to render the disengagement continuous. After 
allowing the action to continue three or four days, I interrupted it and 
proceeded to examine the contents of the flask. 
The alcohol was distilled off, and as the liquid gradually diminished in 
volume, drops of oil separated from it. Only a small quantity of the oil 
could be obtained, and after being purified, was too small to employ in an 
analysis, expected to afford some clue to the composition of the com- 
pound. Intense cold would not render this oil solid.
