1833 Regulations as to Members going Abroad 3 1 1 



" Professor Hamilton," invited by J. G. Children on 

 March 22, may be conjectured to have been William Rowan 

 Hamilton, the pre-eminent Irish mathematician who in 

 1827 was appointed Professor of Astronomy at the Dublin 

 University and afterwards became Astronomer Royal for

 in 1835 an d chosen President of the Royal Irish Academy 

 in 1837. His work on Quaternions gave him a high place

 the Club without being liable to the payment of any 

 contribution." In place of it the following new Rule 

 was adopted : " Any Member declaring his intention of 

 going abroad shall be considered as a supernumerary 

 member during his absence, without paying his annual 

 contribution ; but his vacancy shall be filled up, and on
