never seen in this discussion (on cliraate) any reference to the planet 
Mars, he ought to have added, that it had not occurred to hira to look

THE PILSEN PERMO-CARBONIFEROUS BEDS. 
Sie, — In the extremely interesting paper on the Permo-Car- 
boniferous beds of Bohemia which appears in the current number of 
the Geological Magazine, Dr. 0. Feistmantel appears to rely very 
strongly on the announcement which he says was made by Dr. 
Anton Fritsch at the last meeting of the British Association that he 
considered the Nürschan Gas-coal horizon as a passage-bed frorn 
Carboniferous to Permian. Now when Dr. Fritsch exhibited bis 
splendid series of specimens before the Geological Section, it was 
evident that he avoided carefully expressing any statement of opinion 
as to the exact age of the beds whence they came. A member then 
rose and asked Dr. Fritsch whether he considered the Pilsen Gas- 
coal series as Carboniferous or Permian, or whether he looked upon 
them as passage-beds. The only answer elicited from the cautious 
palasontologist was that it was not yet time to settle the matter, and 
that more work was required before the question was ripe for de- 
cision. In fact, he declined to give any clue as to what his views on 
the subject might be. The Questionee Himself.

THE TERM “CHLORITIC MARL.” 
Sie, — In the review of Cambridgeshire Geology, by the Bev. T. 
G. Bonney, in your last Number, your reviewer takes exception to 
the use in that work of the term “ Chloritic Marl ” as applied to 
the Phosphatic Nodule-bed at the base of the Chalk-marl in Cam- 
bridgeshire and elsewhere. From this it would appear that there is 
some doubt about the proper use of the term, and I should be very 
glad to hear from your reviewer what he considers the true typical 
Chloritic Marl. The question of nomenclature is so important that 
I feel sure your readers will not regret the use of a small portion of 
your valuable space in Clearing up a doubt which seems to exist on 
this subject. H. Geoege Foedham.

PRESIDENT OF THE PAL-EONTOGRAPHICAL SOCIETY. 
BORN JULY 14, 1797- DIED MARCH 8, 1877. 
It is with no ordinary feelings of regret that we record the loss 
of the Founder and President of the Palseontographical Society. 
James Scott Bowerbank was born in Bishopsgate, London, in 1 797. 
He succeeded, in conjunction with his brother, to his father’s dis- 
tillery, in which business he was an active partner until 1847. 
From his youth he exhibited a strong attachment to Natural History 
pursuits, especially to Botany. When of age, he joined the Mathe- 
matical Society of Spitalfields, and remained a member until its in- 
corporation with the Royal Astronomical Society in 1845. Here he
