RESEARCH IN BRITISH WEST AFRICA, 
and the dangers are therefore accentuated ; some such measures as those sug- 
gested should immediately be put into effect. 
During my own stay in Zungeru I caught several Glossina palpalis at various 
places within the cantonment, in some cases within a few yards of European 
bungalows, and several medical officers have obtained the same species at other 
places. It is more than probable that these do not actually breed in the town, 
but come in from the surrounding bush. Mosquitos are far from uncommon in 
Zungeru, but are more abundant along the valley of the Dago River than on the 
higher ground. If at all possible, the residential quarters over the Government 
Offices in Ike Square should for this reason be abolished. Two species of 
Stomoxys, namely calcitrans and nigra, are omnipresent, and are a perfect pest 
and a probable source of danger to ponies, while the number of species, as well 
as of individuals, of the smaller TABANIDAE, is excessively large, especially 
near the polo ground. The clearing already suggested should tend to reduce 
these to a minimum. 
Trypanosomiasis is very common amongst horses in Zungeru, and there can be 
little doubt that many become infected within the cantonment. Not long ago a 
camp was started near the polo ground for transport cattle, but this had to be 
abandoned owing to the high rate of mortality. There is at present a trypano- 
somiasis camp for ponies, but it is’situated too close to the Kaduna, and might 
with advantage be removed to higher well-cleared ground. In the interest of 
the Protectorate such camps ought to be officially recognised and aided, 
Piroplasmosis also is known to occur in dogs, but no records are available to 
show whether or not this disease accounted for any of the deaths in the cattle 
transport lines. 
I should like here to draw attention to one of the regulations of the canton- 
ment, namely, that prohibiting the shooting of any game, large or small, within 
three miles of Zungeru. In consequence of this, small antelopes may often be 
seen within the bungalow enclosures. ‘The question as to whether or not this 
regulation should be continued must necessarily depend on whether these animals 
are or are not a source of danger. For the present we are not in a position to 
make any definite statement, but the blood of these animals should be examined 
for protozooal parasites, and in view of the high mortality amongst horses, 
inoculation experiments with Stomoxys and TABANIDA® should also be carried 
out. It is not at all improbable that such game may act as protozoal reservoirs, 
and that their presence around the cantonment may to a great extent account for 
the infection of the ponies. Should this be proved to be the ease, it is 
obvious that such a regulation should be at once withdrawn. 
The following extracts from a letter sent me by Dr. W. Morrison will give 
some idea of the country immediately surrounding Zungeru :—“ Konoko is a 
small village of about 30 huts, situated near Wushishi, about 8 miles from 
Zungeru [see map]. The general bush is more open than one finds elsewhere, 
but there are a number of kurimis [p. 307, supra], usually with a collection of 
pools of water along the whole extent, and thick dense bush and trees on either 
side, while the lowest parts are swampy. Near these places tsetse were more 
numerous than in any other place I have seen, and I have counted over a dozen
