fierce storm of hail and rain from the south-east, the hailstones being 
as large as horse beans, and continuing for half an hour, when they 
gave place to a perfect deluge of rain. Even during the driest 
season of the year the atmosphere is very moist, as is tbe soil ; and 
Emin noticed the curious phenomenon of partial rains ; he said they 
sometimes occurred in torrents, when at hardly ten minutes’ distance 
there was no rain at all. 
Population . — The population is about two and a half millions 
(1879). The people are Negroes, but they are not quite so fine a 
race as the Waganda, nor are they quite so tall. Their colour is, as 
a rule, a dark reddish brown (Broca’s table. Nos. 42 and 43). 
Colour of the eyes, Broca’s table No. 1. There are, however, a great 
many persons having a much lighter colour than that which is here 
indicated; in fact, they may be said to vary from reddish black to a 
dark reddish yellow, red being, however, the fundamental colour. 
The people are thin but well formed, save that the muscles of their 
legs are not well developed. They have good features and many of 
them are really good-looking; the lips are, however, very thick. Their 
teeth are good, but the four lower incisor teeth are extracted at 
puberty. 
I regret that I have no detailed measurements of the Wanyoro. 
Anatomy and Physiology . — The temperature taken in the axilla 
for five minutes, the subjects being at rest in the shade, at about 
9 a.m., averaged 97'8° (98 observations taken). The number of 
respirations per minute under like conditions varied from 16 to 18 ; 
the pulse averaged 70. Like the Waganda, the Wanyoro do not 
bear cold well ; they keep up fires in their huts during the night, 
and they do not like getting wet with the morning dew ; they do 
not protect themselves from the sun. They are hardy, and bear 
privation fairly well, but are not quite so courageous as their 
neighbours. Their muscles are decidedly red in colour, and the fat 
has a yellow tinge. The mucous membrane of the mouth is highly 
stained with pigment. The skin is velvety, and they do not perspire 
much. The women have sufficient milk. They are delivered in a 
squatting position ; a stake is often firmly driven into the ground, 
and the woman walks round about it in a circle until the commence- 
ment of each pain, when she squats down, supporting herself by the 
stake. Emin mentions that during delivery a woman will some-
