Having thus endeavoured to prove his claim to priority 
of publication, and to establish the independence of his own 
researches, which was all that was necessary for self defence, 
Mr. Mac Cullagh coneluded by saying, that he would there 
drop the argument, without discussing his claim to priority in 
the abstract, as he had an objection to disputes of such a 
kind, and did not wish to pursue them any farther than he 
was compelled to do. But if any one thought it worth while 
to examine the merits of this second question, he would 
find the circumstances relating to it very fully and clearly 
stated in the last number of the Proceedings of the Academy, 
(page 217 of the present volume,) and would thence be 
enabled to form a judgment for himself.

Antiquaries :

3. “We should like to have a catalogue of the princes 
of this district from the earliest times. 
4, “What harbours are there between Broad Haven 
and the bay of Killala? 
5. ‘* What is the right name of the north point of the 
district Majo? (Cape Binir or Cape Calliugh ?) 
6. ‘Is this headland high, and visible from a great dis- 
tance ?
