He read before the Medical Society of London, last year, an account of the first case in which he operated, which was successful; and he read an account of three more cases at Glasgow, in one of which the result was negative, as far as sight was concerned, while in the other two the patients were not only quickly restored to useful vision, in one instance from complete, in the other from nearly complete, blindness, but were at the same time relieved or cured of other symptoms, such as headache and sickness, arising from direct pressure on the brain. In his paper at Glasgow, Mr. Carter claimed for the new operation that it could be performed with certainty and without risk either to life or to any important structure, and that it afforded a reasonable prospect of the preservation of sight in many forms of disease in which it is now habitually or frequently lost. As in the case of every new operation, time and further experience of its effects are required in order to determine the precise limits of its usefulness. In the discussion which followed the paper, Mr. Bickerton, of Liverpool, said that, in consequence of reading the account of Mr. Carter's first case, he had himself performed the operation in two instances, in one of which temporary restoration of sight was followed by relapse, while in the second the ultimate issue was favorable.--_London Times._ * * * * * PUTZEYS' FLUSHING RESERVOIR. Every sewer is more or less exposed to intermissions in the flow of the water that it leads, and the result is a diminution in velocity which leads to deposits of solid material. Hence the necessity of regularly flushing the sewer with water, which removes from the sides the substances that have attached themselves thereto, and which, without such precaution, soon decompose. In a word, it is necessary that a _perfect_ washing shall be assured, and this can be done only by heavy rains or by strong currents of water. As regards rain, that could not be relied upon; and to have a force of men specially charged with the service of washing, that would be too costly, and so recourse has been had to automatic apparatus.
