THE FEVER IN UNYAMWEZI.

bilious remittent, which normally lasts three clays ; it 

 wonderfully reduces the patient in that short period, 

 and in severe cases the quotidian is followed by a long 

 attack of a tertian type. The consequences are severe 

 and lasting even in men of the strongest nervous dia- 

 thesis ; burning and painful eyes, hot palms and soles, 

 a recurrence of shivering and flushing fits, with the 

 extremities now icy cold, then painfully hot and swollen, 

 indigestion, insoinnolency, cutaneous eruptions and 

 fever sores, languor, dejection, and all the incon-

 inordinate secretion of bile, betray the poison deep- 

 lurking in the system. In some cases this fever works 

 speedily ; some even, becoming at once delirious, die 

 on the first or the second day, and there is invariably 

 an exacerbation of symptoms before the bilious remittent 

 passes away.

 the quagga (?), and the koodoo wander over the plains ; 

 and the hippopotamus and crocodile are found in every 

 large pool. The nyanyi or cynocephalus in the jungles 

 of Usukuma attains the size of a greyhound ; according 

 to the people, there are three varieties of colour — red, 

 black, and yellow. They are the terror of the neigh- 

 bouring districts : women never dare to approach 

 their haunts ; they set the leopard at defiance, and, 

 when in a large body, they do not, it is said, fear the lion. 

 The Colobus guereza, or tippet monkey, the " polume" 

 of Dr. Livingstone (ch. xvi.), here called mbega, is ad- 

 mired on account of its polished black skin and snowy-
