156 LIVINGSTONE'S EXPEEIMENT: 



on the right lumbar portion of the pelvis ; the grey 

 buffalo has been sick, but this I attribute to unmerciful 

 loading, for his back is hurt ; the camels do not seem to 

 feel the fly, though they get weaker from the horrid 

 running sores upon them and hard work. There are no 

 symptoms of Tsetse in mules or donkeys, but one mule has 

 had his shoulder sprained, and he cannot stoop to eat or 

 drink "(Vol. I., pp. 33-34). 



Qth May, 1866. On the north hanJc of the Itovuma. — 

 " Tsetse again. The animals look drowsy. The cow's eye 

 is dimmed ; when punctured, the skin emits a stream of 

 scarlet blood." . . . 



" 7th May. — A camel died during the night, and the 

 grey buffalo is in convulsions this morning. The cruelty 

 of these sepoys vitiates my experiment, and I quite expect 

 many camels, one buffalo, and one mule to die yet ; they 

 sit down, and smoke and eat, leaving the animals loaded 

 in the sun." 



" 7th May. — We are now opposite a mountain called 

 Nabungala,* which resembles from the north-east an 

 elephant lying down. Another camel, a very good one, 

 died on the way ; its shiverings and convulsions are not 

 at ail like what we observed in horses and oxen killed by 

 Tsetse, but such may be the cause, however. The only 

 symptom pointing to the Tsetse is the arterial-looking 

 blood, but we never saw it ooze from the skin after the 

 bite of the gad-fly as we do now. 



" 8th May. — We arrived at a village called Jponde, or 

 Liponde, which lies opposite a granitic hill on the other 

 side of the river (where we spent a night on our boat 

 trip), called Nakapuri j . . . One mule is very ill ; one 

 buffalo drowsy and exhausted ; one camel a mere skeleton 

 from bad sores ; and another has an enormous hole at the 

 point of the pelvis, which sticks out at the side. I suspect 

 that this was made maliciously. . . ." (Vol. I., pp. 35-36). 



20^/t May, 1866. On the Loendi B., just above its 

 confluence ivith the Bovuma. — "The black buffalo is dead; 

 one camel ditto, and one mule left behind ill. Were I not 

 aware of the existence of the Tsetse, I should say that 



* From the map, the approximate position of Dr. Livingstone on this 

 day would appear to have been 11'-' 8' S. lat., 38"^ 52' E. long. — on the N. 

 bank of the Kovuma. — E. E. A.
