 The Yeey Rev. Chaeles Geaves, D. D., President, in the Chair. 



The Secretary exhibited an original Bull of Pope Innocent IY., with 

 the leaden seal attached, belonging to the Public Library of Armagh, the 

 tenor of which is as follows : — 



" Innocentius episcopus servus servornm Dei dilectis filiis Archidi- 

 acono Glindelacensi, Priori Sancti Johannis deTristeldermod,Dublinensis 

 diocesis, salutem et apostolicam benedictionem. Conquesti sunt nobis

 quod Prior et fratres Hospitalis Sancti Johannes extra novam Portami 

 et quidam alii clerici Dublinensis Casselensis et Darensis civitatum et 

 diocesium super decimis terris possessionibus et rebus aliis minantur 

 eisdem. Ideoque discretioni vestre per apostolica scripta mandamus 

 quatinus partibus convocatis audiatis causam, et, appellatione dempta, 

 fine debito terminetis, facientes quod decreveritis per censuram ecclesias- 

 ticam firmiter observari. Testes qui fuerint nominati, si se gratia odio 

 vel amore subtraxerint, censura simili, appellatione cessante, cogatis 

 veritati testimonium perhibere. Datum Laterani ii. Nonas Martii, pon-

Innocent IV., whose name was Sinibaldo di Piesco, was elected 

 Pope on the 24th of June, 1243, so that this document is of the date 

 1244. 



The Rev. Professor Haughton read a paper " On the Semi-diurnal 

 Tides of Cahirciveen." 



nication with the ablest shipwrights of the French dockyards ; and a trireme was built 

 upon the principles maintained by the former, with a single rower to each oar, and three dis- 

 tinct levels of rowlocks, or portholes, for each range of oars. After spending infinite pains 

 and much expense in the endeavour to reconcile the three ranges of oars with the real 

 requirements of a vessel propelled by oars, the model trireme was launched, and tried 

 upon the Seine. It proved a signal failure ; no exertion could drive the vessel above 

 three miles an hour against a sluggish stream, and the labour of the huge oars soon ex- 

 hausted the rowers. But the Emperor was not content with a river trial ; he insisted on 

 her being tried at sea ; and here the failure was far greater than in the smooth water of 

 the Seine. The trireme proved quite unmanageable, and it was not without much risk 

 and difficulty that she was towed back into harbour by the steamer prudently sent out to 

 attend the experiment.
