We can see nothing in the above effect at all resembling, or de- 

 pendent upon, electro-magnetism. The attraction at first, if there 

 were any, was common electrical attraction, well known to be ex- 

 hibited by the voltaic poles. The after-adhesion was, most proba- 

 bly, the result of slight fusion at the place of contact — certainly, not 

 of electro-magnetic attraction. — Ed. 



6. Intense Light, — The intense light produced by igniting lime 

 in the oxy-alcohol flame, is well known, and has been beautifully 

 applied in the construction of geodesical signals by Lieutenant 

 Drummond. It is said, that a very ready mode of exhibiting it on 

 a small scale is, to place a small piece of lime on charcoal, lighted, 

 at the spot by a little piece of tinder, and throw a jet of oxygen 

 from an ordinary blow-pipe aperture upon it. 



7. Table of atomic weight of Bodies, 63/ Berzelius. — ^The table by 

 Berzelius is stated to be according to the most recent and exact 

 analyses. We do not think it necessary to give any more of it than 

 that part which relates to hydrogen as unity. The atomic numbers 

 adopted by Berzelius are often double, and sometimes triple and 

 quadruple those of other chemists ; but these cases generally 

 explain themselves, and, for the simple substances in the following 

 list, are marked by preceding figures ; —
