If the earth were a rigid body acted on by no forces rotating about a diameter which is not a principal axis, show that the latitudes of places would vary and that the values would recur whenever *JA-B ^A- C/oyft is a multiple of 2* JllC.

Seen in the proper light, the plainest function shows a spirit of worth and vigour, which far transcends its form— an essence needing only the clothing of a name to give it universal importance. The attempt, then, of this paper is to point out that there is such a principle behind the various aspects of advocacy, and that this principle is the development and security of social harmony and personal freedom....
