was boiled with water for several minutes, the mixture cooled to 
15° and allowed to stand 24 hours. The filtered solution con- 
tained 3°4056 grams, the liter 34°056 grams of this variety, The 
difference in solubility at 15° of the two forms is consequently 
much greater than at 100°. One part of the crystallized oxide 
parts; one part of the crystallized at 100° requires 46 parts, and 
solution.—J. pr. Ch., II, viii, 234, Dec., 1873, .. Fs 
5. On the Constitution of Anthracene.—Two views are held 
t 
separately, e former view would make anthracene belong to 
the 1:4 or para series and may be formulated thus: 
Ci | CHCH t C,H, ; the latter regards anthracene as a 1:2 or 
ortho-derivative, which may be thus written: Cle, yi 1 Olly.

ketone passed over ignited zine dust yields f-benzyl-toluol, which 
then condenses to anthracene ; while the solid ketone thus treated 
gave an oil boiling at 285°, having the composition of benzy!- 
dation, It 
Ing its vapor through a red-hot tube. Hence Behr and Van Dorp 
regard their suspicion as established, and believe that anthracene 
cannot a para-derivative of benzol. Th 
as a 1: 2 or ortho-derivative, and assign to it the second of the 
above formulas.— Ber. Berl, Chem. Ges., vii, 16, Jan., 1874.
