PREFACE. 



The writer had the opportunity of making an eight months' 

 (Dec. 1900 — July 1901) scientific expedition in Egypt and through 

 the regions bordering the White Nile, for the purpose of stud-

 Cand. Th. Odhner and Phil. Cand. I. Tragardh were members 

 of the exploration party. Time was found for extending the 

 scope of the expedition to Tor on the Red Sea and to some parts 

 of the Sinai Peninsula. The publication, of which the first Part 

 is now issued, contains a report upon the collections made and 

 the investigations carried out during the journey. 



The expedition enjoyed the extreme advantage of the gra- 

 cious patronage of H. M. King OSCAR II of Sweden and Norway, 

 to whom we would here express our most humble gratitude. 



The University of Uppsala awarded me, for the investiga- 

 tions I proposed to make in Egypt, the larger of the two travelling 

 scholarships allotted from the national exchequer for its disposal 

 every year. The amount I received from that source was 2000 

 Swedish crowns, and it was supplemented by a grant of 1000 

 Sw. cr. from the Lars Hierta's Memorial Fund. Part of our 

 scientific equipment was very kindly given us by the Zoologi- 

 cal Museums of Stockholm and of Uppsala. 



During the progress of the tour we met with the utmost 

 kindness and assistance in our labours and inquiries. The Eng- 

 lish Minister Plenipotentiary and Consul General in Cairo, Earl
