INTRODUCTION. 



THIS Subject Catalogue of the Cruickshank Science Library 

 contains the titles of about one-third of the books in 

 the Departments of Pure Science (Mathematics, Astron- 

 omy, Physics, Chemistry, Geology, Palaeontology, Biology, 

 Botany, Zoology, Anthropology) and Agriculture, including 

 Forestry and Veterinary Science being those which it is 

 specially desired to bring under the notice of the student. 

 The remaining two-thirds are titled either in the author 

 catalogues printed in 1873-74, 1887 and 1897, or in the 

 manuscript sheaf catalogues (both of authors and of subjects), 

 which may be consulted in the Library. 



To keep the booklet of a convenient size, the titles have 

 been cut down as far as is consistent with clearness. Authors' 

 pre-names are entered as initials only, while the names of 

 editors and of translators are omitted, save in exceptional 

 cases. No cross-references are given from the names of 

 joint authors, and books of composite authorship have not 

 been analysed. 



The system of classification and notation here employed 

 is a modification of that devised by Mr. Melvil Dewey, which 

 is in use in many libraries in all parts of the world. Certain 

 alterations have been introduced, suggested by the publica- 

 tions of the Institut International de Bibliographic of 

 Brussels, and the whole has been adapted to the special 

 requirements of a Scottish Academic Library.
