THE PILSEN PEEMO-CARBONIFEROUS BEDS. 



SiK, — In the extremely interesting paper on the Permo-Car- 

 boniferous beds of Bohemia vfhich appears in the current number of 

 the Geological Magazine, Dr. 0. Feistmantel appears to rely very 

 strongly on the announcement which he says vs^as made by Dr. 

 Anton Fritsch at the last meeting of the British Association that he 

 considered the Niirschan Gas-coal horizon as a passage-bed from 

 Carboniferous to Permian. Now when Dr. Fritsch exhibited his 

 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 

 palgeontologist 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 liis views on 

 the subject might be. The Questioner Himself.

THE TERM " CHLOEITIC MARL." 



Sir, — In the review of Cambridgeshire Geology, by the Eev. 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. George Fordham.

PKBSIDENT OF THE PAL^ONTOGRAPHICAL 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 Paleeontographical Society. 



James Scott Bowerbank was born in Bishopsgate, London, in 1797. 

 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 Eoyal Astronomical Society in 1845. Here he
