A Treatise on Adulterations of Food and Cnhnary Poisons, ex- 

 hibiting the fraudulent Sop/d^ticntions of Bread, Bcsr, Wim, 

 Spirituous Liquors, 7 ea. Coffee, Cream, Confectionary, Vi- 

 vepar, Mustard, Pepper, Cheese, Olive-oil, Pickles, and other 

 Articles employed in Domestic Economy; and Methods vj 

 detecting them. By Fredrick Acchm, Operative Chemist, 

 Lecturer on Practical Chemistry, &c. 12mo. pp. 3S6. 95. 

 The title of this very useful little volume fully explains its ob- 

 ject. The author, in stating the experiments necessary for the 

 detection of the frauds which he has exposed, has judiciously 

 confined himself to such processes as may be performed by per- 

 sons unacquainted with chemical science, and has given 'n^! In- 

 structions in the plainest language, divested of those terms which 

 would be out of place in a work intended for general perusal. We 

 shall take an early opportunity of laying some extracts before our 

 readers. ______ 



Reports made upon the Patent Moveable Inodorous ConvenienceSy 

 by the Royal and Central Agricultural Society of France : 

 with a Supplement by the Comte Francois de Neufcha-

 ciety for the Encouragement of Natural Industry ; The Me-

 and The Medical Society of Paris. Translated from the French.

The invention to which this pamphlet alludes is the subject of 

 a patent in France, and patents have also been granted for it m 

 this country. Its title explains in few words the nature of the 

 invention—^- moveable conveniences;" but the moveablepart may 

 be described rather as the receptacle than the whole apparatus. 

 In fact, it consists of two casks so contrived and adapted to the 

 seat, that they may be removed from time to time, and oUieis sub- 

 stituted in their place ; and all so well fitted that no effluvia can 

 posably escape. In cities circumstanced like Pans, where llie 

 convenience of water-closets, as in use in London, is but little 

 known, this invention offers many inducements for its adoption. 

 The invention however offers other inducements, winch, in a na- 

 tional point of view, as promising an incalculal)le increase ni our 

 agricultural products, render it highly deserving of pubhc at- 

 *> * tcntion.
