"On a regardé le coeur comme le siége de la Mémoire. De là les mots _recorder_, _se recorder_, _récordance_, _récordation_, en Latin _recordari_, _recordatio_; de là aussi l'expression _apprendre par coeur_. Rivarol dit que cette expression, si ordinaire et si énergique, vient du plaisir que nous prenons à ce qui nous touche et nous flatte. La mémoire, en effet, est toujours aux ordres du coeur." J. M. Oxford. "_Suum cuique tribuere_" (Vol. iii. p. 518.).--I beg to refer your correspondent M. D. to Cicero's _De Claris Oratoribus_, which is the nearest parallel passage I can find: viz. "Erat omnius tum mos, ut in reliquis rebus melior, sic in hoc ipso humanior: ut faciles essent in _suum cuique tribuendo_." In a note, an allusion to Justice is made: but my Cicero is a very old edition, and is divided into four tomes. The above is from tome i. p. 305, letter F. The only other parallel passage is from Liber II., "Ad Herennium," thus: "_Justitia_ est habitus animi, communi utilitate conservata, _suam cuique tribuens_ dignitatem." J. N. C. King's Lynn, June 28. 1851. _Frogs in Ireland--Round Towers_ (Vol. iii., pp. 353. 428. 490.).--I must take leave to doubt the fact, mentioned in Vol. iii., p. 490., of the introduction of frogs into Ireland first in the year 1696. They are much too plentiful in the country districts, leaving out their abundance in the county Dublin, to warrant any such supposition. In the Queen's County, particularly, I have seen them in myriads. With regard to those gentlemen who are pleased to import snakes into Ireland, I can only wish them some worthier occupation. There are two birds, the occurrence of which about Dublin I do not find noticed by naturalists. One is the common skylark, the other is the Royston crow, which, strange to say, is not a migratory visitor, but is found there the whole year round. Concerning Round Towers, mentioned at pages 353. and 428., I beg to refer W. R. M. to the works of Wilkinson, Mr. and Mrs. S. C. Hall, and Moore's _History of Ireland_, in addition to Petrie, Keating, &c. When in Galway, in January, 1850, I noticed some remarkable instances of resemblance to Spaniards amongst the peasant women and girls. It was, however, by no means general; but only observable here and there, in a few particular instances. Between Galway and Oughterard I passed a girl walking barefooted along the dirty road, whose features were strikingly beautiful, set off with long raven tresses and large _dark_ eyes, signs apparently of her Spanish origin. The town of Galway is full of interesting memorials of its connexion with Spain, and well repays a visit. Its ancient prosperity will now be probably revived again, and, with its singularly advantageous position, and its future intercourse with America, it cannot fail to rise once more from its ruins and its dirt, unless prevented by the prevalence of political agitation.
