I may mention as a sequel to the brief account of the suit Whistler v. Ruskin, which I sent you a short time since, that the plaintiff has lately published a little pamphlet in which he delivers himself on the subject of art-criticism. This little pamphlet, issued by Chatto & Windus, is an affair of seventeen very prettily-printed small pages; it is now in its sixth edition, it sells for a shilling, and is to be seen in most of the shop-windows. It is very characteristic of the painter, and highly entertaining; but I am not sure that it will have rendered appreciable service to the cause, which he has at heart. The cause that Mr. Whistler has at heart is the absolute suppression and extinction of the art-critic and his function. According to Mr. Whistler the art-critic is an impertinence, a nuisance, a monstrosity--and usually, into the bargain, an arrant fool. Mr. Whistler writes in an off-hand, colloquial style, much besprinkled with French--a style which might be called familiar if one often encountered anything like it. He writes by no means as well as he paints; but his little diatribe against the critics is suggestive, apart from the force of anything that he specifically urges. The painter's irritated feeling is interesting, for it suggests the state of mind of many of his brothers of the brush in the presence of the bungling and incompetent disquisitions of certain members of the fraternity who sit in judgment upon their works. "Let work be received in silence," says Mr. Whistler, "as it was in the days to which the penman still points as an era when art was at its apogee." He is very scornful of the "penman," and it is on the general ground of his being a penman that he deprecates the existence of his late adversary, Mr. Ruskin. He does not attempt to make out a case in detail against the great commentator of pictures; it is enough for Mr. Whistler that he is a "littérateur," and that a littérateur should concern himself with his own business. The author also falls foul of Mr. Tom Taylor, who does the reports of the exhibitions in the _Times_, and who had the misfortune, fifteen years ago, to express himself rather unintelligently about Velasquez.
