It is, I believe, about 18 years since there has been determination of the magnetic variation here, at all events published. It may have been, and very probably was, observed by the American Transit of Venus Expedition in 1874; but, if so, it does not appear to have been published. The most recent authentic observation I can find is that of Dr. Geo. Neumeyer in April, 1863, as included in his "Results of the Magnetic Survey of the Colony of Victoria.
