| KAMMOGRAPH.
About a year ago an American firm (Anthony & | Co., of New York, we believe) introduced in the | United States an instrument of the cinemato| graphic type in which the pictures were taken on a circular plate of glass, the series of pictures being in spiral form. An instrument of somewhat similar style has made its appearance in this country during the past few weeks under the name of the Kammograph.
