wealthier people, who want knowledge less, are to be protected by the law in their purchases of medical works, but if poor people, in sore need, finding "an undoubted physician" ready to aid them, venture to ask for his work, written especially for them, the law strikes down those who sell them health and happiness. They must not complain; Nature and Providence have placed them in a state of poverty, and have mercifully provided for them effectual, if painful, checks to population. The same element of price rules the decency or the indecency of pictures. A picture painted in oils, life size, of the naked human figure, such as Venus disrobed for the bath, or Phryne before her judges, or Perseus and Andromeda, exhibited to the upper classes, in a gallery, with a shilling admission charge, is a perfectly decent and respectable work of art. Photographs of those pictures, uncoloured, and reduced in size, are obscene publications, and are seized as such by the police. Cheapness is, therefore, an essential part of obscenity. If a book be cheap, what constitutes it an obscene book? Lord Campbell, advocating in Parliament the Act against obscene literature which bears his name, laid down very clearly his view of what should, legally, be an obscene work. It must be a work "written for the single purpose of corrupting the morals of youth, and of a nature calculated to shock the feelings of decency in any well-regulated mind" (Hansard, vol. 146, No. 2, p. 329). The law, according to him, was never to be levelled even against works which might be considered immoral and indecent, such as some of those of Dryden, Congreve, or Rochester. "The keeping, or the reading, or the delighting in such things must be left to taste, and was not a subject for legal interference;" the law was only to interpose where the motive of the seller was bad; "when there were people who designedly and industriously manufactured books and prints with the intention of corrupting the public morals, and when they succeeded in their infamous purpose, he thought it was necessary for the legislature to interpose" (Hansard, vol. 146, No. 4, p. 865).
