Omitting No. I., these results correspond with the following formule : — 
TT. = Cy Hye 3 TL. = Cy Heer; IV. = Crp He5;,— instead of C,. H,, as required by 
theory. 
The sp. gr. of No. II. was found to be 0.8697 at 0°, and that of No. III. 0.8882 at 0°. 
A portion of this benzole (No. III.) having been converted into nitro-benzole and 
anilin, there was at once obtained from the latter the purple reaction with hypochlorite 
of lime. Several portions of this anilin having been heated with arsenic acid, there 
were obtained in each instance decided manifestations of the color of anilin-red, though 
the red thus obtained was by no means so brilliant as that subsequently obtained from 
the toluol-fraction 110°-111° (wid. inf.). 
A sample of anilin, prepared from a portion of the impure fraction 83°-84°, which 
fraction had never received any chemical treatment, gave the violet coloration with 
hypochlorite of lime, but it yielded no red color on being heated with arsenic acid. 
Enanthylene = Cy, Hy Above the benzole heap (81°-82°), the quantities of the de- 
gree-fractions were very small, until at 90° they began to increase again, there being a 
prominent heap between 90° and 94°, which amounted to about 300¢.¢. The summit 
of this heap was at 92°-93°. On treating it with diluted sulphuric acid, the acid became 
dark colored, an aromatic odor being at the same time manifested, while a slight odor 
of acetone, which had previously been present, now disappeared altogether. On adding 
water to the dark sulphuric acid liquor, after this had been separated from the hydro- 
carbon, a very penetrating ethereal odor was evolved, while a small quantity of oil, of 
a reddish color, rose to the surface of the water. After the acid treatment and the 
subsequent washing and drying, the hydro-carbon was distilled eight times upon 
metallic sodium, through Warren’s hot condenser. The sodium was very strongly 
acted upon at first, but on the fourth distillation this action had well-nigh ceased. At 
the close of these operations the summit of the heap was at 93°-94°, this fraction 
amounting to about 45 ¢.c., the next fraction (94°-95°), being almost as large (42-43 
c. c.) The fraction 91°-92° was now very small, the heap only beginning to show 
itself at 92°-93°, which was equal to 28 ¢.c. The fraction 95°-96° amounted to only 
about 12 ¢. ¢., andthe residues, at 96°, were each very small. 
Boiled upon sodium, in an ordinary retort, the fraction 93°-94° came over at 94,1°
