XX.--NOTES ON THE PHYSICAL APPEARANCE OE THE PLANET MARS DURING THE OPPOSITION IN 1881. ACCOMPANIED BY SKETCHES MADE AT THE OBSERVATORY, BIRR CASTLE. By Otto Bceddicker, Ph.d.--With Plates XXXVI. And XXXVII. Communicated by the Earl of Rosse. Read April 17th, 1882. The drawings of the planet Mars, which accompany these notes, were made with the reflector of three feet aperture at the Earl of Rosse's Observatory, Birr Castle, Parsonstown, from 1881, Nov. 19, to 1882, January 23, both days included. Unfortunately, the weather was very bad during this period, so that it was impossible to obtain more than twenty-one drawings, eighteen of which are here selected for publication. It would doubtless have been practicable to observe the planet with advantage after the 23rd January, if it had not also been frustrated by the unfavourable state of the atmosphere. The speculum used is the same with which the drawings of Comets b and c, 1881, in these Transactions, Part XVII., (antea page 239 and Plate XIX) have been executed; the power was in all cases 216. The drawings are reproduced as they were made before the telescope. The most conspicuous spots were first put down and the time noted, and the more difficult details gradually filled in in the same degree as they could be discerned with certainty. ...
