habitants of U-nyamwezi is M’-nyamwezi in the singular, and 
Wa-nyamwezi in the plural,” * and “ Ki-nyamwezi is the ad- 
jectival form;”t but he would have continued, “and U-nyam- 
wezi is the region of the people or tribe of Nyamwezi.” 
Several years ago I arrived at the root Nyamwezi by a 
different process. In the month of April 1856, Mohammed 
bin Khamis, a man well known to Captain Burton, had occa- 
sion to visit Mauritius, where I made his acquaintance. He 
is the son of Mr Cooley’s informant, Khamis bin Othman,f 
. and is himself appealed to by that gentleman in his ‘“ Inner 
Africa Laid Open,” being there described§ as “a very intelli- 
gent Sawahili, educated in England, formerly commanding 
one of Sultan Seid S’aid’s ships, but now [1852] secretary 
and interpreter to his highness.” Mohammed became known 
to Captain Burton, fifteen months after his visit to Mauri- 
tius, as the sailing-master of the corvette Artémise, in 
which the traveller and his “ companion” crossed from Zan- 
zibar to the mainland.|| On the occasion of Mohammed’s 
visit to Mauritius, I laid before him Mr Cooley’s recent 
works, the several articles in the ‘“‘Athenzum’ on the vexata 
queestio of one lake or two lakes (the ¢hird and northernmost 
lake, Nyanza, being at that time unknown), and discussed 
with him the merits of the question generally; when he, 
asserted the existence of two lakes; the one, “ Nyassa,” being 
much smaller, more southerly, and nearer to the coast; the 
other, ‘‘ the Monomwezi Lake,” considerably larger, more to- 
wards the north, and much further in the interior. In the 
Sawahili language they are respectively called, Ziwa la 
Wa-nydssa, or the Lake of the Tribe of Nyassa, and Ziwa 
la Wa-nyamwézi, or the Lake of the Tribe of Nyamwezi.J
