longs to the smaller species. The larger, the Troglodytes 
gorilla, stands 5 feet high and upwards. The T. Niger 
is found in various parts of the western coasts of tropical 
Africa, as the Guinea coast and Angola, and also between 
these distant places, as in this instance on the Calabar River, 
thus showing a pretty extensive range. The large Chimpanzee, 
or Troglodytes gorilla, has been brought from the neigh-- 
bourhood of the Gaboon Eiver, nearly under the Line, where 
the T. niger has also been procured ; but future inquirers 
will probably give the former also a much more extended 
range, as the huge Chimpanzees, said to have been seen in 
various parts of western tropical Africa, will probably turn 
out to be the gorilla; and what have been supposed to be 
merely exaggerated tales may thus have more truth in them 
than we have been inclined to give the narrators credit for. 
The killing of one of those formidable creatures is considered 
a great feat by an African brave ; and in this instance, ap- 
parently, the skull had been preserved as of great value, if not 
also for worship. You observe there is a piece of copper wire, 
1 foot 11 inches long, and 2-lOths of an inch thick, which is 
wrapped twice in a vertical direction round the skull, passing 
through the temporal fossae of each side, behind the super- 
ciliary ridge above, and the nasal fossae below. Hammered 
copper wire is the current money of this part of Africa ; so the 
amount of metal used in ornamenting this skull shows the 
high value the owner had placed on it. It was taken, I have 
already mentioned, from what is called a ^:?ef^7-7io^{se, for a cer- 
tain amount of English is spoken by many of the native chiefs 
and traders. This devil-house, as I have been informed by 
Dr Sommerville, Secretary to the Mission Board of the 
U. P. Church, is not, strictly speaking, a place of worship. 
It is, like their dwelling-houses, built of branches of trees 
and clay, and is erected at the death, especially, of a great 
man ; after various ceremonies have taken place, and, in 
former times at least, the sacrifices of human beings, sometimes 
to the number of hundreds, according to the rank of the de- 
ceased — the slain being supposed to be thus sent as his 
slaves and attendants to the other world — their remains are 
buried in one common tomb, and over it this devil-house is
