Eigon. — Under this name Dieterich has placed upon the market three 

 new iodine-albumen compounds. 



1. a-Eigon (iodo-albumen), a light-brown powder, odorless and taste- 

 less, insoluble in water, and containing 20 per cent, of iodine, which can be 

 split off by alkalies or by acids. 



2. «-Eigon-sodium (sodium iodoalbuminate), an almost white powder, 

 odorless and tasteless, soluble in water, and containing 15 percent, of com- 

 bined iodine. 



3. /?-Eigon (iodo peptone), containing 15 per cent, of iodine and having 

 the same general properties as the preceding compound. It is given 

 when even large quantities of iodine are to be rapidly absorbed, especially 

 in case of weak digestive functions, since the iodine is what might be 

 called a predigested condition. 



All three preparations will keep unchanged indefinitely. They are rec- 

 ommended to the use externally in the form of ointments, dusting pow- 

 ders, suppositories, etc. ; for internal use with extract of malt, in pill- form, 

 tablets, or dissolved in syrups, wines or other vehicles.

Alinit. — Under this name the Farbenfabriken vorm. Friedr. Bayer & 

 Co. have introduced into the market a fertilizer for grains. According to 

 the manufacturer the Bacterium Ellenbachii a is said to be the active con- 

 stituent of the fertilizer. Stoklaser, however, claims that the organism in 

 question is identical with B. megatherium, as demonstrated by pure cul- 

 tures of both. Alinit, therefore, consists of the spore-bearing cultures of 

 B. megatherium de Bary evaporated to dryness with some indifferent con- 

 stituent. [Chem. Centr.-Bl., 69, I., p. 789.] Phar. Rev. 



F. H. Knowlton states in The Plant World (p. 142) that he saw pine 

 trees growing near Santa Fe, with their roots bathed in a weak solution 

 of muriate of copper, which, on being cut, yielded an oleo-resin of a beauti- 

 ful emerald hue, showing that considerable quantities of the copper solu- 

 tion had been taken up. H. H. R. 



The Mustards Cultivated in Bengal.— By Surg.-Maj. D. Prain, 

 M.B., M.A., Supt. Roy. Bot. Gard. Sibpur, Calcutta. Reprinted from 

 the Bengal Bulletin No. 4, as No. 1 (1888) of The Agricultural Ledger;

This pamphlet constitutes a notable contribution to economic botany in 

 more than one way, and it is certain to remain, for a long time to come, 

 our standard source of information concerning the species treated. It is so 

 crowded with valuable information and not less valuable suggestions as 

 to be difficult of review except at considerable length. The task origi- 

 nally undertaken by Dr. Prain was to determine the species of Brassica 

 cultivated in the different parts of Bengal by reference to their native
