lodiiio is icpoittMl \\\, J. A. WaiiUlyii to cxi.st in ;i tree Ktate in the 

 luiiieral water of the Woodliall Hpa, near Ijiiicoln. iSulKcieut is preseut 

 to impait a brown color to the water and to give the usual reaction with 

 carbou disulpliide. The spa has long been known as useful in skin 

 diseases (Cliem. News, Liv, 300.) 



The complete syutbesis of pyrrol has been accomplished by Ciamician 

 and Silber; the steps in the transformation from suecinimide to pyrrol 

 are as follows: Succinimide, bichlormaleinimide, perchloride of tetra- 

 chlorpyrrol, tetrachlorpyrrol, tetrajodpyrrol. i)yrrol. (JBer. d. chem. 

 Ges., XIX, 3027.) 



Com bi nations of acetamide with metallic chlorides have been described 

 by G. Andre, notably with cupric chloride, cadmium chloride, the chlo- 

 rides of nickel and cobalt, and mercuric chloride. These bodies are 

 crystalline, and decompose at a moderately low temperature. (Comptes 

 Eendus, cii, 115.) 



Prof. A. Michaelis, of Aachen, continues his extended researches on 

 comi)Ounds of the elements of the nitrogen group with radicals of the 

 aromatic series. In Liebig's Annalen, Vol. ccxxxiii, in union with A. 

 Reese, he describes several compounds of antimony with phenyl aiul 

 its derivatives, and in union with Paetow he describes compounds of 

 arsenic with benzyl. 



Calcined magnesia, showing peculiar behavior with reagents, is sui)- 

 posed by George Stillingfleet Johnson to contain rare earths. (Chem. 

 News, LIV, 88.) 



The mosandra of Dr. J. Lawrence Smith has been examined by Lecoq 

 de Boisbaudrau, samples being furnished by Dr. Marion, of Louisville, 

 and found to consist chiefly of terbia and Ya-. (Chem. News, Liii, 108.) 



Sozolic acid, or orthoxypheuylsulphurous acid, discovered by M. Ser- 

 raut, is a more powerful antisei)tic than salicylic or phenic acids. The 

 corresponding ixtra compound has no antisei)tic properties. The author 

 claims for sozolic acid great benefits to medicine and surgery. (Comptes 

 liendus, Cii, 1079.) 



A summary of all that is known concerning samarium and its com- 

 pounds has been published by P. T. Cleve, of Upsala. The subject is 

 treated uuder the heads history, separation, mode of occurrence, atomic 

 weight, spectrum, oxides, and the numerous salts. (Chem. News, Liir, 

 30 et seq.) 



Cerium, yttrium, and glucinum, according to Dr. J. H. Strohecker, 

 occur in extraordinary quantities in the clays of Hainstadt. One of 

 the clays analyzed contained as high as 13.4 per cent, cerium hydrox- 

 ide. The author's analytical methods and his -statements have met 

 severe criticisms on the part of several chemists, but he insists on 

 their accuracy. (J. f prakt. Chemie, 1886.) 



Glycyphyllin is a crystalline substance, which Dr. Edward H. lien- 

 nie extracted from the leaves of Sniila.r glycyphylla, a plant common 

 in New South Wales. Crystallized from water it has the formula
