Abstract

Sir, I take the liberty of sending you, inclosed, my observations of the transit of Venus, and of the sun's eclipse; which, if you think proper, you may lay before the Royal Society.

I was just prepared to find the difference of declination between the Sun and Venus by your method, which appears to me to be a very good one, when the sun was covered by a cloud, and I saw it no more. The magnifying power of the telescope I made us of was 95.
