Wine placed in jDrepared bladders contracts no bad odour; 

 it assumes a deeper colour, acquires more aroma and a mild- 

 er taste, and becomes generally stronger. Spirits of turpen- 

 tine of 75° contained in a cylindrical glass closed with a 

 bladder, lost nothing in four years. Concentrated vinegar 

 lost the half of its volume in four months, the other half ac- 

 quired more consistency and had no longer an acid taste. 

 The water of orange (lowers, was about one third evaporated 

 in a few months, appeared to have a stronger odor and con- 

 sequently had lost nothing of its volatile principle. — Fcrus-

28. Beet. Sugar in France. — It appears by a letter ad- 

 dressed to Gay Lussac from M. Crespel Dellisse that there 

 was manufactured in 1827, chiefly in the four northern de- 

 partments 1 ,21 8,000 kilogrammes of sugar from beets, (about 

 2,750,000 lbs.) and that several new manufactories of the 

 first order were in a course of erection. 



Agreeably to tlie results stated, says the writer, it cannot 

 be doubted that the fabrication of sugar from beets will be 

 advantageously extended in France. It appears that the 

 process of M. Crespel, of crystalizing the syrup slowly in the 

 stoves is the most advantageous ; it gives a greater quantity 

 of sugar and of finer quality ; but it is to be regretted that 

 it requires so long a time and such large stoves. The ex- 

 pence in fuel is also considerable, which must be taken into 

 account in situations where fuel is dear. This new branch of 

 industry is of the greatest interest to France, and it belongs 

 to an enlightened ministry to observe its progress and to fa- 

 vor its operation. — Ann. tie Ch. et de Phijs. Jan. 1828. 



29. Odors affected hy electricity. — When a continued cur- 

 rent of electricity passes through an odoriferous body, cam- 

 phor, for example, its odor becomes weaker and at length 

 entirely disappears. If the body be then withdrawn and 

 placed in connection with the ground, it remains for some 

 time without odor. Caniphor resumes its former properties 

 by degrees and very slowly. The author of this curious ex- 

 periment, William Libri, of Florence, promises to describe it 

 more in detail. — Idem. 



30. Employment of Iodine as a Dye. — It appears from a 

 note by Pelletjer that he ascertained during a recent journey
