xxii INTRODUCTION. 



With, regard to the orthography of native names and places, 

 Mr. Ravenstein has made it agree throughout the whole book, 

 and the method of spelling recommended by the Royal Geo- 

 graphical Society has been followed. He has also provided a 

 glossary in conjunction with the index, which not only gives 

 the meaning of many native expressions, but the latitude and 

 longitude of the places mentioned. This adds greatly to the 

 value of the book to future travellers and explorers. 



Dr. Gustav Hartlaub of Bremen has appended a note to the 

 German edition, giving his opinion of the services which Emin 

 has rendered to zoology. I quote a few passages from it. He 

 says : — " The amount of work which Emin Pasha has performed 

 in making zoological collections, observations, and notes, is 

 astonishing in the highest degree. It could only have been 

 performed by a man whose heart was aglow with the pure fire 

 of scientific instinct, with enthusiastic, absolutely unselfish love 

 of Nature, and with an irresistible impulse to add to the know- 

 ledge of her treasures to the full extent of his powers. Emin 

 was able to turn this impulse into action, notwithstanding the 

 pressure of difficult surrounding circumstances, and the many 

 and varied duties which his high position compelled him to 

 fulfil.

 own work, which Emin Pasha has either sent to Europe or
