servations of medical men in various nervous and mental 

 diseases. From all the facts before him, the author deduces 

 the following conclusions : 



1. That magnetic effects are only nervous diseases under 

 the form of convulsions, extatic delirium, comatose sleep, 

 somnabulism, &c. 



2. That magnetism developes these cerebral neuroses only 

 in persons predisposed to these affections. 



3. That magnetism is a dangerous process, since it tends to 

 favor the developement of these diseases. 



4. That magnetism is still more dangerous in its moral 

 relations. 



Such are the principal results of this work, which by its 

 mass of facts, and the novelty of its views must very much 

 contribute to extend a knowledge of the nature of animal 

 magnetism. — Bull. Univ. Mars, 1826. 



27. Preparation of Soda from the Sulphate of Soda. — 

 Dissolve, with or without heat, lime or calcareous matter, 

 in pyrolignous acid ; the liquor becomes covered with the 

 vegetable oil which this matter contained, and which can be 

 mechanically separated ; dissolve in the liquor thus saturated 

 with lime, a quantity of sulphate of soda, determined by 

 the degree which the calcareous solution indicates on the hy- 

 drometer for saline solutions, (pese-sel.) By this procedure, 

 the sulphuric acid quits the soda, and forms with the lime a 

 solid salt which precipitates to the bottom of the containing 

 vessel. The supernatant fluid, evaporated and crystalized, 

 gives acetate of soda. This salt, collected dried, and cal- 

 cined, either on the hearth of a reverberatory furnace, or in 

 front of a furnace adjusted for the purpose, gives carbonate 

 of soda, which a warm ley, on cooling, reduces to the state 

 of crystals, of the greatest purity. — Ibid. 



28. School of Arts. — Major General Martin, a Lyonese, 

 who died 25 years ago in Bengal, left to the city of Lyons 

 250,000 rupees, (1,200,000 francs,) on condition that the in- 

 terest should be applied to an institution which should be 

 acknowledged to be the most useful for the public good in 

 his native city. The institution is to be called the Martin- 

 iere. The royal academy of Lyons decided on the 10th of 

 December, that the Martiniere should be a gratuitous school 

 of arts and trades, especially applied to the progress and
