PENDULUM AT THE ROYAL OBSERVATORY, CAPE OF GOOD HOPE. 159 
I am aware that this compression somewhat differs from that obtained in 
the Southern Hemisphere by Sir Thomas Brisbane, at Paramatta, though it 
is nearly in accordance with M. Freycinet’s observations in Cape Town. 
The documents, however, are here given, and I have every hope that they may 
meet the public eye, and undergo the usual test of candid and liberal criticism.

Royal Observatory, Cape of Good Hope, 
May 19 th, 1829 . 
P. S. The latitude of the Observatory is not yet ascertained by actual obser- 
vation with the new mural circle. This instrument has been attached to its 
pier for several months past ; but from some discrepancies in reading, the cause 
of which is not yet discovered, I am under the necessity of assuming 33 ° 55 ' 56 " 
as a very near approximate latitude*. The examination of the mural will go on, 
and the conclusions be forwarded home when some definite opinion may be 
formed of it. 
* I connected the Observatory with my former temporary one in Cape Town, by a survey over the 
intermediate ground.
