The Sydney Observatory is in no way responsible for the altitudes of different places given to the Australian Almanac.
Should you consider it necessary?? to assist?? that publication, I have to request that you will at the same time state that the error was in Dr Wilson’s observations, otherwise it?? is an ?? which has come within my?? own?? knowledge.
It may be supposed from your statements that I am responsible for the mistake in the altitude of Braidwood.
