We did not break up our little Naval Board without mentioning impressment, and a thing called the CAT; the word was no sooner out, than it operated like the morning-gun in "The Critic," and off went the following:-- AN A_CAT_ALECTIC MONODY! A _cat_ I sing, of famous memory, Though _cat_achrestical my song may be; In a small garden _cat_acomb she lies, And _cat_aclysms fill her comrades' eyes; Borne on the air, the _cat_acoustic song Swells with her virtues' _cat_alogue along; No _cat_aplasm could lengthen out her years, Though mourning friends shed _cat_aracts of tears Once loud and strong her _cat_echist-like voice It dwindled to a _cat_call's squeaking noise; Most _cat_egorical her virtues shone, By _cat_enation join'd each one to one;-- But a vile _cat_chpoll dog, with cruel bite, Like _cat_ling's cut, her strength disabled quite; Her _cat_erwauling pierced the heavy air, As _cat_aphracts their arms through legions bear; 'Tis vain! as _cat_erpillars drag away Their lengths, like _cat_tle after busy day, She ling'ring died, nor left in kit _kat_ the Embodyment of this _cat_astrophe.--V. D. L. "A play on words," said Mr. Cavil, (who happened to be our guest on this occasion), "a play on words, sir, is a pretty thing in its way; and I'm perfectly well aware that the public expect you to be jocular (as if there were nothing cheerful in seriousness). I know, too, that it's quite impossible to please everybody. But still, sir--still I think a little gravity now and then, eh?--a little gravity. I don't conceive that you give your attention sufficiently to science. Something scientific now--" Mr. Cavil was not allowed to conclude; we had anticipated his want; we had already turned our thoughts that way, and could fortunately plume ourselves upon the presence of one of the _illustrissimi_ of science, who forthwith illumined our humble vehicle by a transcendent and exclusive report of the THIRD MEETING OF THE BRIGHT-ISH ASSOCIATION FOR THE ADVANCEMENT OF EVERYTHING. _Section A.--Mathematical and Physical Science._ _President_--Prof. Cycloyd. _Vice-Presidents_--Dr. Spectrum & Major Fork. "ON AN EXPERIMENT OF INTERFERENCE." By Inspector Jones.
