APPENDIX 11. 



The appended results of observations of inclination taken at the 

 Koyal Observatory, Cape of Good Hope, have not hitherto been 

 published. So far as we have been able to find the observations 

 were carried out with a dip-circle obtained from Woolwich by Mr. 

 Maclear — afterwards Sir Thomas Maclear. The needles used were 

 marked 1, 2, respectively. In 1854 needle 1 was broken. A new 

 pair — marked 1, 2 new pair — were afterwards used. 



It is evident from the results that the needles did not agree 

 amongst themselves.
