 lil'uges; so he uiay be called the father of antipyretic medicines. Of 

 tiiese, kairine was discovered by Prof. O. Fischer in 1881, and its feb-

 It is actually ethyl-tetraoxy-quinoline, and has the constitution

Autii)yrine, the second of these febrifuges, was discovered by Dr. L. 

 Kuorr, of Erlangen, and its physiological proi)erties were studied by 

 Professor Filehne. It has the following constitution :

Statisfics of the Coal- Tar Color Industry. — In a paper on the scientilic 

 developmeiit of the coal-tar color industry, bj^ Prof. R. Meldola, before 

 the Society of Arts, he gives some statistics showing the magnitude of 

 the industry under discussion. In Germany a factory of about the third 

 magnitude consumes at present 500 to 600 tons of aniline i»er annum. 

 The P)a(lische Company employ twenty-five hundred laborers and otfi 

 cials, and the Hoechst Color Works (formerly Meister, Lucius & iJriin- 

 ing) emi)loy lixteeu hundred men and fifty-four chemists. In these 

 large establishments they manufacture not only aniline, but alizarine, 

 acids, alkalies, and all the necessary chemicals. 



The probable consumption of alizarine by British dye-works in 18S0 

 amounted to 0,900 tons (of 10 per cent, paste), of which perhaps Go 

 per cent, was manufactured in Germany. The author points out that 

 although historically the industry is indebted to English discoveries, 

 commercially the control is leaving England for Germany. (Nature, 

 xxxiv, 321.) 



NOTES. 



Gadolinium is the name definitely given b,y Marignac to the metal Yz-r, 

 which he discovered in 1880. The provisional name was abandoned at 

 the suggestion of Lecoq de Boisbaudran. This is not to be confoumled 

 with the same word as used by Nordenskj«(ld. 



Ammonio permanganate of silver, as well as the analogous compounds 

 of coi)per, cadmium, nickel, zinc, and magnesium are new compounds
