the edges of tlie rima glottidis do not protrude as in that animal and 

 in the Lion. The thyroid gland is double both in the Ocelot and 

 the Jaguar. At the commencement of the a?5op/;fl^«s the mem- 

 brane is puckered up in the Ocelot into a number of irregular folds 

 crossing the strice, which are there very slight and longitudinal so 

 as to form a kind of valve or obstruction : in the Jaguar on the con- 

 trary the stricp are transverse, and there are no valve-like foldings 

 of the membrane between the pharynx and cesophagus. 



The following note by A. P. Palmedo, Esq., H. M. Consul in 

 Corsica, dated Bastia, Jan. 1832, was read. It was communicated 

 to the Committee by Mr. Barnard. 



•' There had been hitherto no instance in Corsica of Moujfflons 

 breeding in a domesticated state, nor any of their coupling with 

 Sheep, though the flocks of the latter not rarely approach the high 

 regions of the Moufflon. General Merlin, the commanding officer 

 of Corsica, has now, however, not only a young Moufflon born of 

 two tame Motifflons in his possession, but also an offspring of the 

 same he-Moufflon and of a Ewe." 



FRIDAV^-EVENING PROCEEDINGS AT THE ROYAL INSTITUTION 

 OF GREAT BRITAIN. 



Feb. 24-, 1832. — The Marquis Moscati delivered a lecture on 

 the Genius of the Extemporaneous Poets, and on the Art of Impro- 

 visation, which he illustrated by improvising several specimens of 

 Italian poetry, at the close of the evening. 



March 2. — Mr. Faraday on the Explanation of Arago's Phaeno- 

 mena of Moving Metals afforded by his late results obtained in inves- 

 tio'atinor mr>gneto-electric induction. The production of electricity 

 from magnetism we have already briefly described in our account 

 of a former evening (p. 301.). Mr. Faraday now pointed out, that 

 when the revolving copper plate, or any piece of moving metal, was 

 passing by the pole of a magnet, the current of electricity, which 

 occurred in the metal at right angles to the direction of its motion 

 and at the place of the magnetic pole, was exactly such as, according 

 to his former discovery of electro-magnetic rotation, would tend to 

 make the pole move tangentially to the current produced, and in the 

 same direction with the moving metal. Upon hanging a powerful 

 horse-shoe magnet over the revolving copper plate, the magnet 

 teiided to move with it ; but on confining the magnet, and applying 

 conductors to the centre and the edge of the plate, the electricity 

 could be drawn off, carried elsewhere by metallic wires, and then 

 be ma.ie to deflect another magnet ; the latter being an exact repeti- 

 tion, by the current conducted from the plate, of the rotating effect 

 of the principal or horse-shoe niagnet produced by the current in 

 the plate. Many other demonstrations of the same point were given*. 



March 9. — Mr. Foggo upon tlie Causes of the Excellence of Gre- 

 cian Art. After which a working model of D'Arcet's apparatus, now 

 used extensively in Paris, for piocuring jelly from bones, was put 

 into operation, and its parts and action were explained.
