FOR THE CABINET. 



Sundry Roman Coins, presented by Dr. Leidy, as Curator of the 

 Academy of Natural Sciences of Philadelphia, in the name of 

 the Southtcark Library Company. 



The Committee appointed at the last meeting on a paper by 

 Dr. _Leidy, •' On Extinct Species of the American Lion," 

 reported in favour of publication, which was ordered accord- 

 ingly. 



Dr. Leidy read a memoir " On the Extinct Dicotylinae of 

 America," — which was referred to Dr. Hays, Dr. Ruschenber- 

 ger and Mr. Lea, as a Committee. 



Dr. Hays exhibited a small Galvanic Apparatus, for medical 

 purposes, which he regards as beautiful and efficient. It fur- 

 nishes an uninterrupted current of electricity, and is therefore 

 devoid of the inconveniences occasioned by the interrupted 

 current. It is the apparatus of Pulvermacher. Dr. Hays de- 

 scribed the apparatus, which he has not yet subjected to trial. 

 He is inclined, however, to think it will answer the purpose. 

 Prof. Frazer has subjected the apparatus to action, which he 

 describes as very feeble. 



Dr. Dunglison, as Clerk, read the proceedings of the Board 

 of Officers and Council, at their meeting, held on the 14th inst. 



Pending nominations, Nos, 275 to 279, inclusive, and new 

 nominations, Nos. 283 and 284, were read. 



Mr. Fraley, from the Committee of Finance, reported on 

 the subject of the "Extra Magellanic Fund," referred to them 

 at the meeting of April 2, 1852, and recommended the fol- 

 lowing resolutions, which, after discussion, were adopted: —
