meats, which were kept in a press or cupboard, but to prevent 
its getting access to them when not wished, the cupboard was 
kept locked. On one occasion the key had been forgotten 
and left lying on the table, the chimpanzee noticed this, 
secured the key, and when no one was present, proceeded to 
unlock the door of the cupboard, but being unable to reach the 
key-hole, drew a chair to the side of it, and getting up on it 
unlocked the door, and so got access to the desired sweetmeats, 
an act involving more than one process of that kind of ratiocina- 
tion which is usually thought the exclusive property of man. 
Galago Murimis. — (Murr.) 
In addition to the information formerly given regarding 
this interesting little animal, Mr Murray had received some 
additional facts, communicated to him by the Kev. W. C 
Thomson, through Dr He wan. From these it appeared that 
the little creatures are gregarious, or social rather, travelling

which was, that they were built on suitable forks on trees, 
with a foundation of clay, and superstructure of dried leaves. 
Stenops., Potto (?). 
Two or three specimens of this curious loxis have been re- 
ceivedj and the singular structure under the tongue (a develop- 
ment no doubt of the frenum, but exceedingly like a bird's 
tongue), as well as the rete mirabile of the arteries of the 
limbs, was well shown in Mr Murray's preparations. 
The sublingual plate is also found in the Galago, although 
less developed. 
Mephitis — Sub Genus Rhahdogale (sp. V) 
Mr Oliphant has received a specimen of an animal which 
Dr Cleland, to whom he has presented it, refers to this genus, 
but he has not yet satisfied himself as to the species.
