The point K will then represent the appa- rent place of the Observatory at midnight. 105. The line K-12 will be the shortest diameter of the ellipse, into which the parallel of latitude appears to be thrown by being seen obliquely ; the point O, midway between K and 12, its centre, and the line 606, drawn through O at right angles to EC, its long- 65 est diameter. The lines 06. Not being foreshortened by being seen obliquely, will appear of the full length of the radius of the parallel, which, ...we know, is the cosine of the latitude. The complement of the latitude of the Observatory is 47°. 2858, and we may find RJl, its sine, in the same way as we did the others. Setting off the distance RR each way from O to 6 and 6, we find the extremities of the longest diameter, which must be the points on the disc where the Observatory will be seen at 6 o'clock in the morning, and. At the same hour in the evening. 106. Its position at any other hour in the day may be found by the following process.
