because it is evidently something analogous to the preponderant use of the right side 
of the head in Giraffes as set forth at another place in this memoir, and also to the 
right-handedness of man. 
In the primeval forest of Kenia Elephants are to be found but whether of the 
same race or not is uncertain. These forest Elephants may belong to the Aberdare 
race (HE. a. peeli). When passing through the forest region between Embu and Meru 
we saw tracks of Elephants several times, and on the way back we were so close to 
them that we heard them break branches etc. At an open place in the forest at an 
altitude of 2,500 m. the Elephants appeared to have a favourite resort between two 
small rivulets. There were spoors everywhere and at two different places around 
some water holes the probably alkaline earth had evidently been dug up by the 
Elephants with their tusks as the marks plainly showed. Close above this place rose 
a hill so steep that it was connected with difficulty for a man to ascend it, but the 
numerous Elephant tracks proved that these animals often passed up and down there: 
The >»steps> in these tracks were often 80 to 100 cm. high above the next. 
'The Elephants ascend on Kenia to, and even above the bamboo region as the 
spoors indicate. At an altitude of 2,700 m. where the temperature at sunrise only 
was + 1” C. the Elephant spoors were numerous. These animals are thus not so 
susceptible to a low temperature as is generally believed. But when the rainy season 
sets in, I was told, that the Elephants descend to the shambas in the cultivated 
region. »They do not like the dripping from the trees.» 
In the Kenia forest I saw in several places the ingeniously arranged pitfalls in 
which the Wandorobbos catch Elephants. They were dug in the paths of the animals 
and often with great cunning, between two big trees, in a curve of the path etc. to 
make it more difficult for the Elephants to avoid them. They were deep but so 
narrow that if an Elephant fell into such a pitfall he should be jammed in by his 
great weight so tightly between the walls that he could not move, and thus not be 
able to work his way out again. 
Perissodactyla. 
Rhinocerotidzae. 
Rhinoceros (Diceros) bicornis LIN. 
The Rhinoceroses were formerly common over great parts of British East Africa, 
but it is now exterminated, or nearly so, near all settled districts and roads along 
which there is any regular traffic, or where too often hunting parties are going in 
search of game. I saw, however, several on the acacia steppe south of Guaso Nyiri, 
and in the dry thornbush country north of this river they were found to be rather
