MM. ERHARDT AND REBMANN. 



53 



notices collected from the natives. It was ac- 

 companied by a ' Memoir of the Chart of East 

 and Central Africa, compiled by J. Erhardt and 

 J. Rebmann.' This production was 6 remarked 

 upon' by Mr Cooley (Jan. 8, 1856), and in turn 

 his remarks were remarked upon by Herr Peter- 

 mann. The peculiar feature of the chart was a 

 ' monster slug '-like inland Sea extending from 

 the line to S. Lat. 14°, — an impossible Caspian 

 some 840 miles long x 200 to 300 in breadth. I 

 have already explained that this error arose by 

 the fact that the three chief caravan routes from 

 the Zanzibar coast abut upon three several 

 lakes which, in the confusion of African vocab- 

 ulary — Xyassa being corrupted to X'yassi, and 

 Xyanza also signifying water — were naturally 

 thrown into one. It was, however, to ascertain 

 the existence of this slug-shaped article that the 

 East African Expedition of 1856 — 59 was sent 

 out. 



The most valuable results of Dr Krapf's 

 labours are his works on the Zanzibarian lan- 

 guages, and these deserve the gratitude of every 

 i raveller and student of African philology. The 

 principal are, 



Messrs Krapf's and Isenberg's imperfect out- 

 line of the Galla language (London, 1840).
