26. Lithography. — M. Montin has discovered near the 

 town of Cervesa, in Spain, a quarry of stone fit for Li- 

 thography. From experiments made at Madrid, in the 

 Hthographic press of de Briissi, its quahty appears excel- 

 lent. This discovery will be extremely advantageous to 

 Spain, and even to the south of France. 



27. Maestricht. — A school of mutual instruction has 

 been some time established here, of which 250 of the pu- 

 pils did not know even the alphabet, on their admission. — 

 Nine months are found sufficient to enable them to read; 

 but, what is more, in another nine monihs they become 

 acquainted with the French as well as the Dutch Language, 

 by reciting the lessons alternately in both. Their progress 

 in writing is not less rapid, and in 18 months they learn to 

 calculate. Many among them that had been for years in 

 other schools without learning to count beyond a hundred, 

 have acquired such a habit of calculating and reasonmg, 

 that the most difficult problems do not discourage them. 

 Next year we shall learn how much time will be requisite 

 for the study of the grammar of the two language?. The 

 principles of linear drawing are to be taught to those in the 

 8th writing class. The success of this school shows that 

 simultaneous instruction in the two languages, is perfectly 

 adapted to border schools. 



28. Besancon — France. — The Academy of Science 

 and Belles-letters of this town, ofFers a gold medal for the 

 best essay on the question — To tvhat extent has the princi- 

 ple of honour contributed to the splendor and true glory 

 of the French Monarchy ? 



29. JVew Astra- Lamp. — M. Georget, larnpist. Rue St. 

 Honore, No. 2, Paris, makes new lamps, of which the 

 reservoir of oil is placed above the light, so that it furnishes 

 a constant level by a uniform conductor. The crown, thus 

 becoming useless, is suppressed; whence it results that the 

 shadow produced by the horizontal circle cannot tiike place. 

 These lamps have the further advantage of being easily 

 transported, without the least danger of spilling the oil.
