superior merits of the productions of the Crown Perfumery Co. They 

 have been awarded twenty-one First Prize Medals besides many 

 diplomas. Some of these exclusive products are Crown Lavender 

 Salts, Bathodora, Crown Bath Salts, and the world-famed extracts 

 Crab-Apple Blossoms, Lune De Miel (Honey Moon), Iroma. 



These are but a few selections from a long line of perfumes, toilet 

 soaps, bath soaps, shampoo preparations, etc., all distinguished by 

 the same high standard which the Crown Perfumery Co. maintains. 



These high-class productions were introduced into South America 

 by Mr. L. C. Houck. Another interesting fact should be noted here. 

 In 1894 The Crown Perfumery Co. gained a firm footing in Mexico 

 and Cuba under the generalship of Mr. S. A. Foot. Mr. Foot is now 

 the Ivlanager of the Sundries Department of Messrs. Lehn & Fink, 

 and of course his energies will again be devoted to the interests of 

 the Crown Perfumery products in the United States. A repetition 

 of his old Mexican successes is assured. 



CHLOROPHYLL.* 



By Curt P. Wimmer, M.A., Phar.D. 



The Dutch scientist Ingenhouss Vas probably the first one to dis- 

 cover that carbon dioxide is assimilated by the plant. This was in 

 1779. His observations were confirmed by Theodore de Saussure of 

 Geneva in 1804. Their announcements caused a sensation and were 

 thoroughly ridiculed and really not accepted until Liebig's time. The 

 name Chlorophyll was given to the green coloring matter of the plant 

 by Pelletier and Caventou in 1817. ' This term "chlorophyll" applies 

 strictly to the coloring matter and not to the so-called chlorophyll 

 granules of the plant cell. 



Chlorophyll does not occur alone but always associated with two 

 yellow coloring matters, namely Carotin and Xanthophyll. These sub- 

 stances are embedded in granules of albumenoid composition. The 

 shape of these granules is, in most plants, that of a lentil. In some 

 algae we find them, however, in the shape of bands, or plates or stars. 

 In a few cases, the chlorophyll is evenly distributed over the entire 

 plasma. In the higher forms of plants, we find chlorophyll bodies in 

 all greoi plant parts, namely in the leaves and here again in or below 

 the palisade cells which line the upper side of the leaf, which side
