upon the paper ; or, it is better to mix it previously with the color-

 It facilitates the action of screws, and from its unctuosity, may be 

 employed with much advantage, for diminishing the friction of the 

 parts of machines which are made of metal. [Rdin. Joiirn, 



Use of Sugar as an antidote to Lead in cases of Poisoning. 

 The following fact has been stated by M. Revnard, to the So- 

 ciete des Sciences of Lisle : During the campaign of Russia, seve- 

 ral loaves of sugar had been enclosed in a chest containing some 

 flasks of extract of lead. One of these flasks having been broken, 

 the liquid escaped, and the sugar become impregnated with it. 

 During the distresses of the campaign it was necessary to have re- 

 course to this sugar ; but far from producing the fatal results which 

 were expected, the sugar formed a salutary article of nourishment 

 to those who made use of it, and gave them a degree of vigor and 

 activity which was of the greatest service in enabling them to sup- 

 port the fatigues of marching. Hence M. Reynard thinks that 

 sugar might be adopted for preventing the effects of subacctate of 

 lead, instead of the sulphates of soda and of magnesia, which are 

 not always at hand. {^Lond. Mech. Mag. 



HOTICES. 



NEW INVENTIONS. 



Messrs. Pearson & HowE,of Alna, Me. have taken out a patent 

 for a newly invented Machine for making Sugar Boxes. The 

 boards are cut, edged, and halved by machinery. It would also 

 serve for making any kind of boxes or chests and trunks. They 

 have one in successful operation in Alna. 



Reaping and Thrashing Machine. 



We have examined a Machine for reaping and thrashing grain 

 by horse power ; recently invented by Mr. Samuel Lane, of Hal- 

 lowell, Me. It is simple in its construction, and promises to be y 

 valuable acquisition to the class of labor-saving machinery. It 

 might also be used for mowing as well as reaping where the ground 

 is sufficiently smooth and level. — Drawings and descriptions of the 

 above Machines will be given hereafter.
