ANNIVERSARY ADDRESS OF THE PRESIDENT. xli 
tice, and often suffering from ill health. Heart disease has taken 
him off suddenly (at the age of about forty-eight) from amongst his 
friends, before his well-loved work was finished as he wished ; but 
he had always given his best attention to the advancement of 
science in general, and of geology in particular, among the com- 
munity around him; and having always identified himself with 
the Literary and Scientific Institutions of Port Elizabeth, and 
showed the greatest personal interest in its public Library, Mu- 
seu, and public Hospital, his townsmen, who, in large numbers of 
all grades of society attended his funeral, regret him as a kind 
warm-hearted friend,—a loss which will not be readily replaced.—

Captain L. L. Boscawen Ipperson died on the 8th of September, 
1869, at Biebrich, in Prussia, where he had resided for several years. 
Whilst a resident in this country, Capt. Ibbetson was on terms of 
intimate friendship with the late Prof. Edward Forbes, in conjunc- 
tion with whom he communicated to this Society a description of 
the section between Blackgang Chine and Atherfield Point, in the 
Isle of Wight, which was published in the first volume of our Quar- 
terly Journal. He also communicated to the Dresden Natural- 
History Society, Isis, a notice of the Cretaceous formation of the 
Isle of Wight, and presented several papers on geological subjects 
to the British Association. For many years Capt. Ibbetson devoted 
much of his attention to the preparation of models of various inter- 
esting sections of country, and to the application of the electrotype 
process to the coating of perishable natural-history specimens with 
metal, in order to preserve accurate representations of them. 
Capt. Ibbetson presented his valuable collection of fossils to the 
Museum of Practical Geology many years before his death. 
KE. W. Brayzey, F.R.S., F.L.S8., for many years Librarian to the 
London Institution, was a pupil of Prof. Brande at the Royal Insti- 
tution, and as early as the year 1824 published, in the ‘ Philosophical 
Magazine,’ a paper on luminous meteors, a subject which occupied his 
attention nearly to the close of his life. His principal contribution 
to our science is his paper on the formation of rock-basins, published 
in the ‘ Philosophical Magazine’ in 1830. Mr. Brayley possessed a 
wide range of knowledge, and his printed memoirs, although not 
numerous, include papers on Physics, Astronomy, Chemistry, Zoology, 
and Meteorology. He died rather suddenly on the Ist of February, 
1870. 
Joun Nasm Sanpers was one of a small body of enlightened 
citizens who, as long ago as during the first decade of the present 
century, established a Bristol Philosophical Society ; and the foun- 
dation of the noble Institution which in 1820 sprang out of that 
combination, and which now boasts a museum that is rich in wany 
and unique in some objects, may be ascribed mainly to efforts which
