Tuts is the third volume of Mr Acloque’s Fauna of France, Coleoptera 
appearing in 1896, Orthoptera and the remainder of the insects in 
1897. We are promised a fourth and last volume to contain the 
Vertebrata and Tunicates. We are also indebted to the author for a 
flora which appeared in 1894. Acloque takes his subject genus by 
genus, giving a brief diagnosis of each of them, then following on with 
the species recorded from France, he similarly gives short diagnoses and 
localities. The numerous figures are sketchy, but no doubt charac- 
teristic and useful for identification. There is room for a book on this 
plan dealing with the English fauna. 
BIBLIOGRAPHY OF MEXICAN GEOLOGY 
BIBLIOGRAFIA GEOLOGICA Y MINERA DE LA REPUBLICA MEXICANA, FORMADA PAR 
RAFAEL AGUILAR Y SANTILLAN. 4°, x+158 pp. Mexico: Oficina tipografica de 
la Secretaria de Fomento. 1898. 
Dr Rafael Aguilar deserves hearty thanks for this excellent and 
compendious Bibliography. No less than 1953 items in the geology 
of Mexico are sufficient to appal anyone who knows the weakness of 
our London libraries on special subjects of this kind. The list is 
arranged in double columns, under authors in alphabetical order, while 
the last eight pages are devoted to indexes of the principal localities 
cited and of the more important matters. It is well and clearly 
printed and will be a great accession to all geological libraries and 
students. 
BIBLIOGRAPHY OF WESTRALIAN GEOLOGY 
THE first Bulletin of the Geological Survey of Western Australia, is 
devoted to a Bibliography by Mr A. Gibb Maitland. Mr Maitland, 
who was formerly on the Geological Survey of Queensland, has 
arranged this under authors, and like so many of these useful works 
it was originally compiled for his own convenience. Mr H. P. 
Woodward, his predecessor, assisted Mr Maitland with a list of works 
extracted from the catalogues of the British Museum. As the Biblio- 
graphy contains Papers, Reports, and Maps bearing upon the 
Mineralogy, Mining, Geology and Palaeontology of Western Australia, 
we need not refer further to its importance. 
Dr Cuas. Davison hopes to publish, with Messrs Cornish of Birming- 
ham, a volume on the Hereford Earthquake of December 17th, 1896, 
provided that a sufficient number of subscriptions be obtained to 
cover the cost of its production. 
This earthquake was one of the most important ever recorded in 
this country. Though inferior to the Essex earthquake of 1884, with 
regard to the damage done to buildings, its disturbed area was at least 
twice as great, being not less than 100,000 square miles. It was felt 
in every English county, except the three northern ones, over the 
whole of Wales and the Isle of Man, and in the eastern counties of 
Ireland. The number of observations on which the discussion is
