^ l.-On the notation of a Solid Body round afixedFoint; being an Account of 

 the late Professor Mac Cullagh's Lectures on that Subject. Compiled by the 

 Rev. Samuel Haughtox, Fellow and Tutor of Trinity College, Dublin 



Kead April 123, 1 849. 



The following Essay, on the Rotation of a SoHd Body round a fixed Point has 

 been compded from my notes of Professor xMac Cullagh's lectures, deUvered in 

 the Hdary Term of the year 1844, in Trinity College. A short account of some 

 01 he results contained in u was pubhslied by Professor Mac Cullagh him- 

 self, in the Proceedings of the Royal Ksh Academy.* As it has appeared to 

 many of Mr. Mac Cullagh's friends desirable that a somewhat more detailed 

 account of his researches in this subject should be published, I have in ac 

 cordance with this desire, drawn up and presented to the Academy the following 

 account of his lectures on Rotation. I have endeavoured to arrange the subiec! 

 in a systematic order, and to give the results proved by him during the course 

 of the lectures, carefully excluding all theorems and proofs of theorems which 

 were not origmally given by him, as here stated.
