The scientific advantages of travel are enormous to a man prepared to profit by them.  He sees Nature working by herself, without the interference of human intelligence; and he sees her from new points of view; he has also undisturbed leisure for the problems which perpetually attract his attention by their novelty.  The consequence is, that though scientific travellers are comparatively few, yet out of their ranks a large proportion of the leaders in all branches of science has been supplied.  It is one of the most grateful results of a journey to the young traveller to find himself admitted, on the ground of his having so much of special interest to relate, into the society of men with whose names he had long been familiar, and whom he had reverenced as his heroes.

To obtain Information.—­The centres of information respecting rude and savage countries are the Geographical, Ethnological, and Anthropological societies at home and abroad.  Any one intending to travel should put himself into communication with the Secretary, and become a member of one or more of these Societies; he will not only have access to books and maps, but will be sure to meet with sympathy, encouragement, and intelligent appreciation.  If he is about to attempt a really bold exploration under fair conditions of success, he will no doubt be introduced to the best living authorities on the country to which he is bound, and will be provided with letters of introduction to the officials at the port where he is to disembark, that will smooth away many small difficulties and give him a recognised position during his travels.

Information on Scientific Matters.—­Owing to the unhappy system of education that has hitherto prevailed, by which boys acquire a very imperfect knowledge of the structure of two dead languages, and none at all of the structure of the living world, most persons preparing to travel are overwhelmed with the consciousness of their incapacity to observe, with intelligence, the country they are about to visit.  I have been very frequently begged by such persons to put them in the way of obtaining a rudimentary knowledge of the various branches of science, and have constantly made inquiries; but I regret to say that I have been unable to discover any establishment where suitable instruction in natural science is to be obtained by persons of the age and station of most travellers.  Nor do I know of any persons who advertise private tuition in any of its branches whose names I might therefore be at liberty to publish, except Professor Tennant, who gives private lessons in mineralogy at his shop in the Strand, where the learner might easily familiarise himself with the ordinary minerals and fossils, and where collections might be purchased for after reference.  An intending traveller could readily find naturalists who would give lessons, in museums and botanical gardens, adapting their instruction to his probable wants, and he would thus obtain some
