— The Stefanite aluminum process aims at introducing alumi- 

 num into iron, either in the blast-furnace, the cupola, or the pud- 

 dling-furnace. During the process of manufacture, the liberation 

 of .the aluminum from its ores goes on concurrently with the 

 manufacture or melting of the iron, the newly formed metal be- 

 ing instantly alloyed with the iron. It is well known that a 

 minute percentage of aluminum has the effect of lowering the 

 melting-point of iron and steel, rendering it extremely fluid, so 

 that it can be run with great facility without blow- holes. The 

 cost of the process has hitherto rendered its adoption very 

 slow, in spite of the great economies which have been ef- 

 fected by the various electric and electrolytic processes for the 

 production of aluminum. It is with the intention of reducing 

 this' cost that the Stefanite process is being introduced. It is not 

 in actual operation in this country, the trials which have already 

 been made having been conducted in Germany. As communi- 

 cated to Engineering, the method of operation consists in the ad- 

 dition to the iron ore in the blast furnace, or to the pig in the 

 cupola, of emery and alum, either in powder or made up into 

 briquettes. It is stated that the re-action of the alum on the em- 

 ery gives rise to vapors of metallic aluminum, which instantly 

 alloy themselves with the iron, imparting to it the improved 

 qualities which have hitherto been, gained by the addition of alu- 

 minum or ferro-aluminum in the ladle or the crucible. The sub- 

 sequent blowing does not volatilize the aluminum which descends 

 with the iron. When the materials are added in the puddling- 

 furnace, the bars, we are informed, can be hardened and tem- 



pered like steel, while their tensile strength is increased. The 

 invention is in the hands of Mr. Thompson Freeman, of 3 Victoria 

 Mansions, Westminster, London, England. 



— " Nature's Wonder Workers" is the title of some short life- 

 histories in the insect world, by Kate R. Lovell, which the Cassell 

 Pubhshing Company have ready. In this book the author's aim 

 is to interest the reader in what are called the " useless insects." 



— " Suijposed Tendencies to Socialism " is the title of the article 

 that will open the March Popular Science Monthly. It is by Pro- 

 fessor William Graham of Belfast, who gives his reasons for ex- 

 pecting a progressive improvement in the state of society, but no 

 sudden social transformation. " Iron- Working with Machine- 

 Tools " will be the special topic of an article in the American In- 

 dustries Series. This division of the series is to conclude with 

 an account of the steel-manufacture. In the tariff discussions of 

 recent years, sisal has been one of the articles most frequently 

 mentioned. How it is produced and what it looks like may be- 

 learned from the illustrated article on "Cultivation of Sisal in 

 the Bahamas," by Dr. John I. Northrop. One of several articles 

 announced fofthe same number of the Popular Science Monthly 

 is an explanation of Dr. Koch"s method of treating consumption, 

 by Dr. G. A. Heron, a London physician, and a friend of the dis- 

 coverer. An explanation of the real nature of Voodoo, traces of 

 which are found among the negroes in our Southen States, with 

 a description of the strange and wild ceremonies connected with 

 it, will also appear in this number. The writer, Hon. Major A. 

 B. Ellis, is an officer in the British Army.
