and camels were first bitten by the Tsetse-fly " (Vol. I., 

 p. 17).^ 



" 17th April [1866].-^I fear that my experiment with 

 the Tsetse will be vitiated [it seemed likely that the camels 

 and bufialoes would die owing to their being overloaded 

 by Livingstone's sepoys], but no symptoms yet occur in 

 any of the camels except weariness " " (Vol. I., p. 23). 



On the north hnnJc of the Bovuma River, 20th April, 

 1866. — " Tsetse are biting the buffaloes again. Elephants, 

 hippopotami, and pigs are the only game here, but we see 

 none : the Tsetse feed on them " (Vol. I., pp. 24-25). 



23rd April, 1866.^ — "Buffaloes bitten by Tsetse again 

 show no bad effects from it : one mule is, however, dull 

 and out of health ; I thought that this might be the 

 effect of the bite till I found that his back was so strained 

 that he could not stoop to drink, and could only eat the 

 tops of the grasses. An ox would have been ill in two 

 days after the biting on the 7th " (Vol. I., p. 26). 



30th April, 1866. — On the north hanh of the Bovuma 

 Biver, near Nachuchu : approximate position according to 

 Dr. Livingstone's map, 11° 2' S. lat., 39° 28' E. long.— 

 " Buffaloes again bitten by Tsetse, and by another fly 

 exactly like the house-fly, but having a straight hard pro- 

 boscis instead of a soft one f ; other large flies make the 

 blood run. The Tsetse does not disturb the buffaloes, but 

 these others and the smaller flies do. The Tsetse seem to 

 like the camels best ; from these they are gorged with 

 blood — they do not seem to care for the mules and 

 donkeys " (Vol. L, p. 30). 



ith May, 1866. On the north bank of the Bovuma, icest 

 of the N'konya Biver. — " The buffaloes were bitten again 

 by Tsetse on 2nd, and also to-day, from the bites of other 

 flies;}: (which look much more formidable than Tsetse), 

 blood of arterial colour flows down ; this symptom I never 

 saw before, but when we slaughtered an ox which had been 

 Tsetse-bitten, we observed that the blood had the arterial 

 hue. The cow has inflammation of one eye, and a swelling 



* " Dr. Livingstone was anxious to try camels and Indian bufEaloes in 

 a Tsetse coitntry to see the effect upon them." — Editor's Note. 



t Obviously a species of Stomo.rys : the " other large flies " which 

 caused the bufialoes to bleed must have been horse-flies (Tabanidje).
