Tsetse-fly on the Okavango, or Tioge or Tonhe Biver, at its 

 junction with Lake Ngami.—'^ He [Pere Duparquet] would 

 have preferred, he says, to begin his description from Lake 

 Ngami, instead of devoting his attention to the portion of 

 the river between Libebe and the country of the Amboellas 

 (in about 16° S. lat.), but few particulars were procurable, 

 as, owing to the presence there of the Tseise-&y, this part 

 of the river is but little frequented."

Belt of Tsetse-fly wider and more continuotis inland 

 from Dar-es-Salaam than farther to the north ; fly found 

 40 miles from the coast.—" Early in the present year Dr. 

 Kirk made an interesting journey, in company with 

 Captain Foote, R.N., along the road recently made at 

 the private cost of Mr. Mackinnon and Sir Fowell Buxton 

 towards the interior of East Africa from Dar-es-Salaam. 

 . . . The presence of the Tsetse-fly in the country 40 

 miles from the coast further renders the employment of 

 horses or bullocks as beasts of burden out of the question ; 

 the belt of fly-country is, in fact, here wider and more' 

 continuous than it is further to the north."
