19. Manufactory of Thimbles. 



A thimble manufactory has been established in France 

 by Rouy and Berthier, in which the mechanism is so in- 

 genious and perfect that they can afford to make steel thim- 

 bles lined with gold and of elegant workmanship, at the 

 rate of eighteen or twenty francs per dozen. The same kind 

 of thimbles lined with silver, can be afforded at six or seven, 

 per dozen. Common iron thimbles, closed at the end, can 

 be sold for one franc per dozen. 



In this single branch of manufactory, France has been 

 tributary, it is said, to other countries, to the amount oi 

 875,000 francs. At present it is supposed that French 

 thimbles will be sought after in other countries — Bui. Soc.

20. Auscultation. 



This singular method of discovering the various disor- 

 ders of the chest by percussion, was, we believe, first sug- 

 gested by Avenbruggen, a physician in Venice, who pub- 

 lished a work on the subject, since translated by M. Corvi- 

 sart. A memoir has lately been presented to the French 

 Academy, by M. Lacunec, detaihng the various modes of 

 employing this discovery. 



Among others, Mr. L. recommends using a tube witli 

 thick sides, or a cylinder, pierced along its axis with a nar- 

 row aperture. Tliis, on being applied to the chest of a 

 person in good health, who is speaking or singing, produces 

 a sort of trembling noise more or less distinct; but if an ul- 

 cer exists in the lungs a very singular phenomenon happen?.
