The man who sends conscience-money for income-tax must have been virtuous indeed, if the evasion of that impost has been through life his worst sin. There are many otherwise estimable persons whose greatest pride it is that they have never paid income-tax unless compelled. Yet these men have in ordinary matters the greatest abhorrence of anything mean or paltry, and their general conduct might be safely contrasted with that of the bestowers of conscience-money. So, after all, there is something more than a joke in the humourist’s idea of a grand new patriotic song called “Never pay your taxes till you’re summoned, my boys!” Those who wear artificial teeth must have been now and again indescribably shocked by advertisements like the following, which, scarce a short time back, are getting more and more frequent, so that what at first appeared a revolting riddle to the many, may have now developed into a lucrative pursuit for the few. Is it right to suppose that new sets of teeth are made up from second-hand materials? If so, how horrible! WANTED to PURCHASE some OLD ARTIFICIAL TEETH. Persons having the above to sell can apply, with the teeth, or, if forwarded by post their value will be sent per return.--Mr ----. Theatrical advertisements are, as has been remarked, often very funny, and whether from ignorance on the part of the writers, or the prevalence of technology, the columns of the _Era_ absolutely teem with startling notices, which when coupled with the really remarkable as well as “original” correspondence, and the provincial critiques, make the chief theatrical organ one of the most genuine among comic papers, and this is none the less so because the _Era’s_ comicality is unintentional. A fair specimen of the general style is given in an advertisement appearing in March 1874, and if our reproducing it will be of any use to Messrs Gonza & Volta, they are quite welcome. In fact it would be sad to think that such an effort should go unrewarded:-- Nil Admirari. GONZA and VOLTA!!! GONZA and VOLTA!!! GONZA and VOLTA!!! The Modern Hercules and Achilles. The Goliathan Gymnasts. The Champions of Olympia Resuscitated. The greatest Athletes since the Christian Era.
