Speaking of cancer, the press and the political world are greatly concerned at the probable fate of the crown prince of Germany, attacked with cancer in the larynx, and with little or no hope of surviving. They announce as the result of the great scientific investigation prompted by this fact, a "_great discovery concerning cancer_." Is it a discovery of a cure--oh no, they think they have discovered the _cancer bacillus_. That is science, but as for destroying the cancer bacillus they leave that to the physicians whom they call quacks for curing what the professors cannot cure. OBSTREPEROUS AND PRAGMATIC VULGARITY.--The house of Knoedler & Co., leading art dealers in New York, has been arrested by Comstock for selling photographs of celebrated paintings from the art galleries of Paris. It is a foul mind which sees obscenity in that which cultivated people admire, and the Hoboken Evening News says very appropriately, "Of all the cranky Pharisees allowed to run at large, Anthony Comstock is the chief. He is a most unmitigated nuisance and requires most emphatic and summary suppression." The N. Y. _Home Journal_, in a well considered editorial, says: "The need of a revision of the law regarding immoral publications in literature and art becomes every day more manifest. There is required especially a precise definition of what the statute is designed to prohibit. At present there is no uniform criterion. It is just what the local Dogberry and the scratch jury happen to find. Books that have had an established place in literature for generations and are found in all the great libraries of the world; pictures that represent the highest skill attained in the leading schools of Europe; reproductions of works that adorn the national and royal galleries cherished as monuments of genius to reflect the glory of the time,--these are quite likely to be brought up and solemnly condemned by our tribunals as unfit for the contemplation of our superior American virtue. But the real injustice of the proceeding follows in the infliction of fines or imprisonment on the unsuspecting vendors of the works, who naturally imagine that merchandise current in all the other markets of the civilized world would be current also here. The most respectable houses, known throughout the length and breadth of the country for their honorable dealings, are exposed to legal prosecution any moment that an officious fanatic or jealous rival pleases to bring a charge that certain works in their store have an immoral tendency."
