Opposition of Mars, 1892. Observations made at the Royal Observatory, Cape of Good Hope. By David Gill, LL.D., F.R.S., H.M. Astronomer.

When Professor Eastman's programme reached the Cape I removed the declination micrometer frame of the transit circle, and with the apparatus which is attached for this purpose to our Repsold photograph-measuring micrometer ruled a pair of lines upon it and inserted a new pair of webs, 16" apart, parallel to the old declination web.

Subjoined are the data relative to the distance and inclination of the wires thus inserted.

The distance between the wires at the middle wire was found to be 16" 03.

The inclination was determined as follows:

1. The transit circle pointing north was placed horizontal, and the north collimator was rotated about its optical axis till the horizontal web of the collimator became parallel to that of the transit circle.

2. The south collimator was directed upon the north collimator, and its horizontal wire adjusted to parallelism with that of the north collimator.

3. The transit circle was then directed to the south collimator, and the inclination of its horizontal wire with respect to the corresponding collimator wire was measured. It is clear that half the apparent inclination of the horizontal web of the transit circle to that of the south collimator will then be the true inclination of the transit-circle web.

The process is an exceedingly accurate one, independent determinations on June 23, 27, 29, and 30 giving practically

identical results.
