The chemistry of essential oils and artificial perfumes, E. J. I'arry (Lmt- 

 don, 1!>08, 2. al.. rcr. and ml., pp. l7//+5-'/6". Jigs. 21). — This second edition 

 (E. S. li., 11, p. 618), has been thoroughly revised and enlarged to include recent 

 researches. A chapter on terpeueless oils lias been omitted and an appendix, 

 which gives the requirements of the i)rincii)al pharmiicoiKeias. has been added. 

 There is a brief treatment of general metliods of preparation and analysis of 

 essential oils and the mixture of the coniiiounds contained therein. The main 

 part of the book consists of a systematic study of oil-producing plants and special 

 uu^thods of preparation. Considerable eniijhasis is given to the variation in 

 I he properties of oils produced by diflerences in soil, climate, and general 

 conditions of growth. 



Perfume plants, P. IIueeut (I'lunlcs a I'arfuinti. Paris, 1000, pp. XI1+(U0, 

 figs. 172). — This is a treatise on the technology of perfumes. The first part is 

 devoted to the chemistry and manufacture of perfumes. In the second part tlie 

 cultivation and preparation of each perfume-producing plant is described in 

 detail. The third part consists of a directory of officials in the French colonies 

 and of dealers in perfumes and materials used iu their production. 



The determination of fatty acids in soaps, G. Fendler and L. Frank; 

 (Ztschr. Angrir. VJian., 22 (1900), No. 6, pp. 252-261, figs. 3; abs. in Analyst. 

 S.'f (1900). \(j. 397, p. 166). — This is a discussion and description of methods. 



Oleaginous products, T. E. Heenan et al. (Mo. Cons, and Trade Rpts. [U. K.J, 

 1909, Xo. 3','/. pp. /JJ-Zo'ti).— Consuls from China, Great Britain, India, Turkey, 

 and Mexico report present trade tendencies in vegetable oils from their re- 

 spective stations. Improved methods have been devised for obtaining oil from 

 the soy bean, which is the principal product of Manchuria. Large shiimients 

 have recently been sent to I<]ngland, where the oil is used as a substitute for 

 cotton-seed oil and the residue is converted into cattle feeds. 



In India, ghee made from cow's milk is preferred to butter by the masses of 

 the Hindus, and formerly sold for 25 per cent more than butter. Within the 

 l)ast 2 years the price of ghee has increased more than 125 per cent. There is 

 a good opening for the sale of a substitute for ghee made from cotton-seed oil. 



The past 2 years the olive crop has been a partial failure in Turkey, and 

 recently the government prohibition has been removed from the importation of 

 cotton-seed oil. It is thought that a good trade can be developed in cotton-seed 

 and oleo oils from the United States. The consular agent of Oaxaca, .Mexico, 

 writes that the lowlands of Mexico afford a rich field for the palm-oil industry 

 and describes a recent invention for hulling the nut. 



Thirteenth annual convention of the Interstate Cotton-Seed Crushers' Asso- 

 ciation (\at. Provisioncr, J/O (1909), Xo. 21, pp. 20-5.'iL; OH, Paint and Drug 

 Reporter, 75 (1909), Xo. 21, pp. 28C-2SX). — This is an account of the proceed- 

 ings of the association, which met at Memphis, Tenn., May IS to 20. Many 

 papers were presented of practical value to those engaged in the cotton-seed 

 products industry. Among these, methods of sampling and analyzing cotton-seed 

 prcKlucts were discussed, and papers were presented on the desirability of a 

 uniform moisture basis for reporting analytical results, and on (he increas(>d 

 \alue to the planter and oil mills by seed deveUti)menl. A pajuM- by A. M. Sonic 

 is noted on page o(!T of this issue. 



The investigation of molasses feeds, M. Gonnermann (Ztselir. Offenll.
