Dr. Vogt, it would appear, had his doubts on the subject, so far as houses are concerned, and in a recent number of the Zeitschrijt filr Biolor/ie, detailed the experiments he made to determine the point. He took three square plates of sandstone fifty-one centimetres in length and fourteen millimetres in thickness, and attached to each plate a zinc photographer of the portrait of the candidates by the . The means used were rather vessel was enclosed in a case of wood and packed with hair, by which means all the heat communicated to the water could only reach it through the plate in front. These plates were then placed in an open space, one to wards the east, one to the west, and one to the south. Owing to the bad weather of last year, uninterrupted hourly observations were very difficult to obtain; but on two days—July 25th and 29th—these were accomplished, and with a result which must certainly be called unexpected. The readings of the thermometers unmistakably showed that the stone facing the south, though it was twice as calico screens thoroughly saturated with water. A couple of these made of calico stretched on light wooden frames about six feet by three, well drenched, will speedily give a refreshing coolness.

The Aspect and Temperature of Studios.—Ilas any one ever taken note of the difference in the temperature of studios having a south aspect compared with those facing east and west?

" Should that fated year not do, Try eighteen hundred and eighty-two.” Some may ask, what has the end of the world to do with photographers? Well, not much; saving and excepting that they, with other units, may be supposed to feel some curiosity concerning the fate of the globe. But upon what some consider a kindred subject—the termination of the temporal power of the Pope—they ought to have a deep and absorbing interest, for it appears that the ninth Pope in succession after the present one—there are to be but eleven more of them altogether—has for his motto, “ The Photographer.” The prophecies relating to the popes are attributed to Archbishop Malachi, of Armagh, who lived in the twelfth century, and to each pope of the nineteenth century he has given a character in the shape of one of these mottoes. Thus Pius VII. is described as “ A Rapa- were—on July 25th, east 100°, west 75°, and south 68° ; and on July 29th, cast 100°, west 88°, and south 86°.
