MAES IN THE AUTUMN OE 1877.

astronomy generally (who are far too numerous for the purpose) 
are assigned the oceans, seas, continents, and lands of the planet. 
The chart as a whole, thus modified, becomes M. Flammarion’s 
chart ! 64 La carte que je viens de tracer,” he says, 44 est done 
en realite un cinquieme essai.” Elle 44 represente exactement * 
l’etat actuel de nos connaissances sur la geographic de ce monde 
voisin.” In reply to Dr. Terby’s somewhat energetic recla- 
mation on his own behalf and mine, M. Flammarion coolly 
rejoins that Eiccioli’s nomenclature replaced that of Hevelius, 
and not improbably his will replace mine. This may or may 
not happen, and in itself it matters little which nomenclature 
is adopted, so that confusion be avoided. But the reference to 
Eiccioli is a little unfortunate. The following passage in my 
44 Moon ” was written three years before M. Flammarion’s new 
chart was formed, and certainly without any expectation that 
it would ever be useful to point a moral ; M. Flammarion 
would hardly wish to have his new names adopted in the same 
way as Eiccioli’s, as thus described: — 44 Father Eiccioli of Bo- 
logna published in 1651 a much less valuable chart than that of 
Hevelius. He adopted a new system of nomenclature, replacing 
the terrestrial names of Hevelius by the names of astronomers 
and philosophers. Madler says, indeed, that Eiccioli’s work 
would have been forgotten, had he not been led by vanity to 
find a place for his own name on the moon — an arrangement 
only to be achieved by displacing all the names used by Heve- 
lius, at the risk of causing perplexity and confusion to later 
astronomers. The charge is rather a serious one.” Strangely 
enough M. Flammarion has in the most marked way left the 
most striking feature of Mars — the Kaiser Sea — with no other 
name than Mer du Sablier or Hour-Griass Sea. Whether the 
hint will be taken remains to be seen. 
* Dr. Terby considers the corrected chart inferior in accuracy to mine, 
and after the study of a great number of views of the planet, I feel confi- 
dence in asserting that Dr. Terby’s opinion is just. Some of the features as 
drawn by M. Flammarion are scarcely recognizable. 
EXPLANATION OF PLATE VII. 
Six stages of Martian rotation, separated by 60° or four hours of Martian 
time. In fig. 2, the first meridian of the chart passes about 30° east of the 
centre of the figure.
