The Planet Mars. — M. Flammarion has published a chart of Mars, in 
which he has not only altered several of the features shown in Mr. Proctor's 
chart, but has introduced several alterations in the nomenclature. Dr. 
Terby, of Louvain, has expressed strong objections to both orders of change, 
and in particular to the fact that while M. Flammarion’s chapter on the 
geography of the planet is based almost entirely on the researches of M. 
Terby, due notice has not been given of the fact by M. Flammarion. The 
latter, in reply, has expressed the opinion that the matter is not worth con- 
troversy ; to which M. Terby has objected, not ineffectively, that results 
which are not worth controversy should not have seemed worth abstracting 
without acknowledgment. M. Terby considers Mr. Proctor’s chart alto- 
gether more correct than the new one, so far as M. Flammarion’s chart is 
new, which is perhaps not saying much. This is not the first occasion by 
several on which M. Flammarion has honoured other students of astronomy 
by borrowing their results. 
The Total Eclipse of the Moon. — Mr. T. Rand Capron, in an interesting 
account of the total eclipse of the moon on February 27, remarks that during 
total obscuration the moon shone with a diffused weak copper-tinted light, 
and with what appeared a marked deepening of the dusky tint towards the 
centre of the disc. At no time was the tint absolutely dark. The loss of 
light was, however, during obscuration very marked. At times a crimson 
scarlet tint, deeper and less mixed with yellow than the copper tint, was 
noticed. u This last tint,” says Mr. Capron, 11 reminded me much of a 
crimson glow common during aurora, and which I also once distinctly re- 
marked — of course in a weaker degree — in the zodiacal light. The colours, 
when seen telescopically with a low power, were but little reduced in 
strength ; the illuminated part of the moon coming out of a steel-grey, an 
effect which also took place when an occasional mist cloud passed over the 
moon’s face.” 
Opposition of Jupiter. — Jupiter will be at his first station on April 20th, 
at 2 a.m., in opposition at midnight on June 20th, and at his second station 
at 3 a.m. on August 20. It may be hoped that much will be done during 
the interval between April 20 and August 20, to observe Jupiter with special 
reference to the questions which have recently been raised respecting this 
interesting planet.
