sel which was to carry it to the isle of Mauritius. The vessel ar- 

 rived safe, the case was disembarked and opened before the customs, 

 and instead of dry and sapless wood as was expected to be found, 

 trees covered with leaves and flowers, much to our surprise were to 

 be seen. These trees were afterwards distributed among several in- 

 habitants of the colony." — Comptes Rendus, August, 1837, p. 260. 



SHOOTING STARS. 



M. Arago announces that an extraordinary appearance of shooting 

 stars took place in the night of the 10th to the 1 1th of last August. 

 His eldest son, who is no astronomer, and one of his friends, walking 

 in the garden of the Observatory, counted not less than 107 between 

 a quarter past 1 1 and a quarter past 12. From 12 h 37 m to 3 h 26 m at 

 the beginning of the twilight, MM. Bouvard and Laugier, astrono- 

 mical students, observed 184 of these meteors. The greater number 

 seemed to take a direction towards Taurus, as was to be expected 

 from the direction of the motion of translation of the earth. — Comptes 

 Rendus, August, 1837, p. 184-. 



CORRECTION IN THE REV. N. S. HEINEKEN S PAPER ON THE 

 SHOCK-MULTIPLIER. 



To the Editors of the Philosophical Magazine and Journal, 

 Gentlemen, 

 I shall feel obliged if you will have the goodness to make the 

 following correction in the paper relating to the " Shock Multi- 

 plier" inserted at page 460 of the last Number of the Philosophical 

 Magazine. The passage commences at the fifth line from the bot- 

 tom of the page, and should stand thus : " If a wire have a moist 

 sponge attached to one extremity while the other is connected with 

 one of the poles of a battery, and the hand grasp the moist sponge; 

 — and if the other pole'of the battery be connected by a wire with 

 N, the other hand grasping a second sponge connected with the 

 wire O, a rapid succession of shocks will, &c." I am, &c.
