PREFACE TO THE EIGHTH EDITION. 
With a view to extending tlie usefulness of f Hints to Travellers/ the 
Council of the Royal Geographical Society resolved to publish the present 
enlarged edition in two volumes. 
In Yol. I, “ Surveying and Practical Astronomy/’ much that appeared 
in the seventh edition has been retained, but important additions have 
been made. These include a new set of examples of astronomical com¬ 
putations, considerable expansion of the section on surveying, including 
photographic surveying, a graphic method of predicting the occultation 
of stars by the moon, and an entire set of tables, by the use of which and 
the “ Nautical Almanac/’ the traveller will be able to compute the results 
of his observations. For permission to insert these tables, the Society is 
indebted to the firm of J. D. Potter, the proprietors of Raper’s well- 
known “ Practice of Navigation.” 
In Yol. II, “ Meteorology, Photography, Geology, Natural History, 
Anthropology, Medical Hints, etc./’ the sections on Meteorology and 
Medical and Surgical Hints have been entirely rewritten and greatly 
enlarged, while the other sections have been revised by the authors 
whose names appear at the head of the chapters containing their 
contributions. 
Hints on Outfit, etc., will be published in a separate pamphlet. 
I am indebted to Colonel St. George C. Gore, r.e., Surveyor-General 
of India, for kind advice and assistance; and my thanks are due to 
Mr. E. A. Reeves, Map Curator, r.g.s., for looking through the proofs. 
John Coles.
