Gnu, I left Msongozi’s on the 
Loangwa R. and struck down the 
valley with the object of making 
Kambombo’s. But I had only 
gone one day’s journey to Mwan- 
kanka, when we were fired on by

Mr. R. E. Holding exhibited 
and made remarks on a fine shed 
antler of the Circassian Red 
Deer (Cervus maral), which had’ 
been shipped with a cargo of

9 Ibs. 2 oz., its length of beam 
41 inches, length of brow-tine 18

an abnormal pair of horns of the 
Wild Goat from the Caucasus, 
having a curious inward spiral 
form (see figure).
