I3y acting npon one molecule of diphenylrnethane with t w o molecules of bromine under appropriate conditions, Libronio-diphenylnietliaiie limy be formed. This when heated with water is decomposed into benzophenone and hydrobromic acid. If one molecule of bromine is used instead of two, monobrornodiphenylmethane is formed. The alcoholic solution of the latter acted upon by alcoholic potassri f o m s mixed etliglbenzohydrolic ether. Uy treatling with amylic alcohol iiistead of ethylic, anti potash, amylbenzohydrolic etlitr is produced, 01‘ if potassic acetate and acetic acid are used we obtain acetate of lienzohydrole.

I n this reaction one molecule disulphonic acid anti two niolcculcs of resorcine participate ; a condensation takes place, water bcinp: given off, and a product is formed, possessing a formula analogous to resorcinephthaleine. T h e analytical results differ, in part, considerably from the calculated composition, and the author therefore assumes that as yet he has not obtained a product free from by-products produced in the reaction. Phenol diviilphonic acid gives with phenols a similar reaction; the product is likewise highly colored. On Isop?&thalop?&enone, E. ADOR(13, 320).

These were printed in Jeita's Zeitschrift fuer Naturioissenschaft, Supplement to Vol. XIII. Since then, the author has examined the action of carbonic oxide upon mixtures of Sodium amylate and sodium acetate, Sodium phenylate and sodium acetate, Sodium phenylate and sodium carbonate, Sodium ethylate and sodium carbonate, Sodium ethylate and sodium benzoate, Sodium ethylate and sodium phenylacetate, Sodium phenylate and potassium oxalate, Sodium ethylate and potassium oxalate, Sodium ethylate and sodium succinate, and also the action of carbonic oxide upon sodium ethylate and sodium cinnamate. The investigation will be continued, and will embrace the action upon polybasic alcohols. The Synthetic P r e p a r a t i o n of F o r m i c A c i d , 0.

Carbou bisulphide and water, with iron filings in excess, heated to 100' for some time in a sealed tube, produced iron sulphide, iron formate, carbon dioxide and also two more substances of more complicated composition.

be driven off by boiling a solution of the salts to be tested for chlorine, with lead peroxide and acetic acid. They pass off mainly as bromine and iodine; a small portion, however, is converted into bromic and iodic acids, which remain with the lead peroxide added in excess. After filtration the solution may be tested for chlorine. T h e reaction is reliable enough for quantitative deterrninationu. Cinnumic Aldehyde obtained b y the Pancretctic Digestion of' Fibrine, J.

The hydrocarbons produced are the same as those produced by the action of iodine upon oil of turpentine. T h e hypothesis t h a t oil of turpentine produces under the influence of iodine first cymole, seems therefore in part a t least verified. Iodine acting upon camphor produces the same hydrocarbons.
