1841. No. 30. 



June 14. 



SIR Wm. R. HAMILTON, LL.D., President, in the Chair. 



James Patten, M.D., was elected a member of the Aca- 

 demy. 



Dr. Aquilla Smith read a paper " On the Irish Coins of 

 Henry VII." 



In the preliminary remarks, the author entered at some 

 lengthinto the history ofthelrish coinage during the reignsof 

 Henry V. and Henry VI., with tb'^" view of facilitating his 

 inquiries in the subsequent part of bis essay. And from the 

 evidence of several Acts of Parliament, which were not 

 known to previous writers on the coinage of Ireland, he in- 

 ferred that no legal money was coined in this country by 

 Henry V., and that very few coins are known which can be 

 appropriated to his immediate successor. 



The coins of Henry VII., which are very numerous, 

 were divided into three sections, each distinguished by the 

 form of the cross on the reverse ; and in the last section the au- 

 thor supported Mr. Lindsay's appropriation to Henry VII. of 

 the untressured groats which Simon had given to Henry V. 



Rev. H. Lloyd, V. P. read a " Note on the Mode of ob- 

 serving the vibrating Magnet, so a» to eliminate the Effect 

 of the Vibration."
