leaves. Buchholz watched them rolling up the leaves and 
cementing them together with a white silky matter proceeding 
from the mouth. The termites were of a smaller species than 
those at Akkra, and their nests did not exceed 2 feet in height. 
They have two kinds of workers, and only one kind of soldiers 
with unsymmetrical mandibles. The queen’s cell was not larger 
than the other cells. In no instance could Buchholz find a king, 
or two queens in the same nest. From Aburi he was able to 
send home no fewer than 700 butterflies. It appears that the 
natives have already adopted the Eucalyptus as a remedy for 
fever. After his arrival at Camaroons, Dr. Buchholz found it 
necessary to separate himself from his companions, Liihder and 
Reichenow. 
Among the Duallas, Buchholz remarks the frequency of 
albinism, which sometimes occurs ir. patches, producing a pie- 
bald appearance. He considers it a mistake to pronounce the 
negroes of this coast as defective in the calf of the leg. He 
finds them, also, by no means very prolific. It is rare for a 
woman to have more than two children. 
The price of a slave at the time of his visit was about £1. He 
considers that slavery and the slave-trade have not been called 
into existence by the necessities of European colonies in hot 
climates, but are original phenomena, connected with the very 
nature and character of the black race. 
Whilst at Victoria, which he paints in no very pleasant colours, 
Buchholz made a careful study of Chamceleo superciliaris, Owenii, 
cristatus, and montium , the last mentioned being new to science. 
The district swarmed with splendid butterflies, beetles of the 
curious family Cassididas, robber-flies ( Asilus ), dragonflies, &c. 
But, whilst collecting and studying these creatures, he was him- 
self studied by the most offensive mosquitoes ( Simulium ), sand- 
flies small as dust, but occasioning intense torture, and Glossinae, 
a form bordering on the redoubtable Tsetse of South Africa. 
Unfortunately the author had not the opportunity of anointing 
himself with kerosine oil, which several American naturalists 
have found very effectual in keeping blood-sucking flies at bay. 
Spiders were remarkably scarce. Almost the only ones seen 
were small hunting-spiders. Several new Batrachians were 
observed, especially a species of the genus Plantyinantis, 
hitherto found only- in Australia and the Malayan islands. 
Chiromantis Guineensis, a large brown tree-frog, deposits its 
spawn in frothy white masses upon the leaves of trees, in which 
the larvae make their appearance. 
Whilst at Victoria he experienced many attacks of fever, and 
was rarely well. He found the decodtion of Eucalyptus of little 
value. Mention is made of a poisonous serpent ( Atractaspis ) ; 
it is about seven feet in length, and of a black colour, and 
occasions much damage. In the beginn'ng of the year 1873, 
Dr. Liihder died, and Dr. Reichenow, shattered in health, re- 
turned to Europe, so that Buchholz remained alone.
