To obtain anhydrous alcohol, strong alcohol is to be saturated with 
chiorid of calcium, and the portion first distilled from it is to be treated 
with the dry sulphate until the blue color ceases to appear. These ex- 
periments should be performed in closed vessels, to prevent the inter- 
ference of atmospheric moisture. GCS 
12. On the Compounds of Phosphoric Acid with Aniline ; by Ep. 
€. Nicnotson, (Phil. Mag., Jan., 1847.)—The facility with which the 
salts of aniline crystallize, led to the attempt to investigate its several 
phosphates, which might be supposed analogous to the phosphates 
of ammonia. Two tribasic phosphates were obtained, one being 
2(HO,C,,H,N)HO, PO,, the other (HO,C,,H,N,) 2HO, PO,, cor- 
responding to the ammonia salts, and like them anhydrous. The at- 
tempt to form the salt with three equivalents of base or one containing 
soda (analogous to microcosmic salt) was unsuccessful. ‘Two pyrophos- 
tes were formed at the same time, acid and neutral ; the latter could 
not be isolated ; the former (HO,C,,H,N,) HO, PO, corresponds to 
a 
acid phyrophosphate of soda, but has no analogue in the ammon! 
seri 
The metaphosphate was formed similar to the soda salt; the ammo- 
nia salt exists only in solution. 
e conclusion is a natural one, that organie bases form series of 
salts with polybasic acids resembling those of the metallic oxyds. 
13. On the relations of Glycocoll and Alcargene; by Mr. THomas 
8. Hunt.—We have received an interesting paper from Mr. Hunt on 
the relations of these two bodies, which we defer to our next number. 
He points out the fact that the formulas of the two bodies are the same, 
excepting the substitution of As for N, and instances some of the ho 
mologous compounds as follows :— aig 
Glycocoll, C,H, NO

Hydrochloric * C,H, NO,, HC! 
Aleargene, C,H, AsO,

and other modifying planes. 
One of the two crystals submitted to my examination by Mr. Bergho- 
fer, is a perfect and distinct octahedron, whose axis measures three 
quarters of an inch. The mineral cleaves with extreme facility pat 
allel to the faces of the cube. Its lustre is between metallic adaman- 
tine and imperfectly metallic; the color ranges between dark reddish- 
brown and brownish-black, and in the thinnest films obtained by cleav-
