Here is a very serious charge. I am accused of foisting on the public a marvellous account of the eclipse, which my own negatives contradict; but I shall have no difficulty in shewing conclusively that Mr. De la Rue has made a blunder, when he says that "there is evidence of the telescope having moved, or, perhaps, followed irregularly." It would have been better had Mr. De la Rue produced his evidence before he takes upon himself to assert that the negatives contradict my statements. But the crimes I am charged with are, that on the 7th of August last, some person or persons did, accidentally or maliciously, disturb the telescope, during the exposure of plates Nos. III. and IV., and that the said plates mislead, and are not faithful representations of the phenomena seen and also, that they contradict the statements of Commander Ashe, with regard to the "rapid shooting out of a certain prominence." In clearing myself of these heavy charges, I shall divide my evidence into two parts-negative and positive. In the first place, the telescope was firmly placed upon a platform made by the heavy sleepers borrowed from the railway station, and surrounded by boards, as may be seen in the photograms; and Commander Ashe has been too long at sea to travel 1398 miles with a heavy telescope, and then not to be able to give it stability. There were four persons inside the building--Mr. Falconer, seated some distance from the telescope, observing the general appearance of the eclipse with the naked eye; Mr. Stanton upon a platform, ready to uncover and cover the object-glass with a light cloth; Mr. Douglas in the dark room, and myself at the telescope, which was firmly clamped in hour-angle, and declination. The people outside were at a distance upon an elevation, and were quite still. The telescope, if it moved, must have moved in hour-angle, or declination, or in both; if it moved in hour-angle, the endless screw must have tripped upon the driving-wheel, which it could not do without making a noise, which would have been heard by me. If it moved in declination, Mr. Stanton must have moved it in uncovering the object-glass; but in so doing, he must have given the telescope a pretty hard blow, of which he must have been aware. But neither Mr. Stanton nor myself are aware of any disturbance of the telescope. There was no wind, which would only have caused a vibration, and given a blurred image. In examining Nos. I. and II. photograms, the limb of the moon may be clearly traced, and there is not a shadow of suspicion of any relative motion in the telescope. Here we have proof that the driving clock was performing its duty well for the first half of totality; and no one will have the hardihood to say that it altered its rate in the next minute and a-half. In looking at No. IV. photogram, we see that a point of light is double. Now, we will suppose this duplication was caused by the telescope receiving a smart blow; then, by drawing a line
