pletely tlie most celebrated volcanoes of Europe, and many of tbe American 
continent, as well with regard to its internal structure as concerning its 
relation to the modern eruptions. There exists between Thera and the 
Kaimeni islands the same relation as between Somma and Mount Vesuvius 
— between the Serra di Fogo and a wider cone of 9,000 feet — a relation 
which we find again recurring between the Pic of Tenerif and the Canadas 
mountains, by which it is surrounded.” This opinion is supported by many 
analogies, and is doubtless correct ; but it is not original, having been long 
ago pronounced by the great geologist, Von Buch, who looked upon the 
whole crater as one of u elevation” rather than of deposition. No one who 
has read the history of the late eruption, and who glances at the photographs 
and maps of Messrs. Reiss and Stiibel’s work, can fail to be impressed with 
the belief that Kaimeni stands in the same relation to Thera and the sur- 
rounding islands as Vesuvius does to the Somma ; that is to say, it is the 
modern and active eruptive centre, situate within the ancient and extinct 
eruptive centre which surrounds it. The maps have been prepared upon the 
plan of those published by our Admiralty, but have been drawn to a con- 
siderably larger scale, and help to clear up the ideas suggested by the 
photographs. We have much pleasure in commending this work to the 
notice of our geological readers. 
MEDICAL BIOGRAPHY.* 
T HE work, which was begun in 1865 by the late Dr. Herbert Barker, is 
being continued by his friend, Dr. Tindall Robertson. Its object is to 
present the public with a series of photographs of the more celebrated phy- 
sicians and surgeons of this and other countries, accompanied by short sketches 
of the various incidents which have characterised their lives. We regret that 
we can only speak from our experience of a single number, but, in so far 
as our own judgment goes, the editor and photographers have discharged 
their respective duties with credit to themselves and satisfaction to their 
subscribers. Dr. Robertson appears to show no partiality either in the selec- 
tion of his biographical subjects or in his method of treating them. The 
examples chosen in the number before us, — Drs. William Augustus Grey, 
Robert Gardiner Hill, and Mr. R. W. Dunn, — are all distinguished members 
of the profession ; and the history of the successive labours by which they 
raised themselves from mediocrity to fame, has been truly and pleasantly 
given by the editor. Dr. Robertson avoids, as far as possible, those lauda- 
tory digressions in which so many biographers indulge, and endeavours to 
state facts without giving them more than their natural colours. In this he 
has been successful, and the result is therefore eminently satisfactory. In the 
pages of this work readers will find all the important facts in the history 
of our “eminent medical men” stated with clearness, accuracy, and
