30. Saw moved by Mechaniwi. — It is stated in an official 

 report made to the Society for the Encouragement of Na- 

 tional Industry, Paris, that the mechanism invented and ap- 

 plied by Brunei, in England, has been ascertained (accord- 

 ing to an investigation made by order of the British admiral- 

 ty,) to produce an annual saving to the government of seven 

 thousand pounds sterling ; and as a mark of benevolence 

 and esteem for M. Brunei, this sum has been guaranteed to 

 him, notwithstanding he has for a long time derived a liber-

 try in France, expended during the year 1821, in the various 

 objects of its association, the sum of 43,955 y^o francs. Its 

 income during the same year was 49,838//^ francs. A 

 benevolent individual (M. Jollivet,) who died in 1818, be- 

 queathed to this Society the sum of about 300,000 francs, 

 one half the income of which is to be at the disposal of the 

 Society in the delivery of annual premiums for the encour- 

 agement of national iagenuity and enterprise. The other 

 half is to be applied, during sixty years, to the augmenta- 

 tion of the capital, at the end of which time the patriotic 

 testator hoped that the Society would be in possession of a 

 fund sufficient to enable French industry to triumph over all 

 foreign competition. If this Society should cease to exist, 

 the fund is to pass over to such other analogous institution 

 as the government may appoint to receive it.

 as defective in this country as the superficial remarks of 

 travellers would represent it. Within this little king- 

 dom there are 673 elementary schools, 266 for the Lat- 

 in language, 21 for Rhetoric and Greek, 27 for rational and 

 mora! philosophy, a university at Coimbra with six facul- 

 ties, and a college for preparatory studies. The university 

 and the college enumerate, annqally, from 1280 to 1600 sty-
