Summary

One of the most important total eclipses of the Sun. that has occurred within the last few years was that of July 28, 1851.

Airy, the Astronomer Royal, who observed it at Göttenberg: —

I took off the higher power with which I had scrutinised the Sun, and put on the lowest power (magnifying about 34 times.). With this I saw the mountains on the Moon perfectly well. I watched carefully the approach of the Moon's limb to that of the Sun, which my graduated dark glass enabled me to see in great perfection: I saw both limbs perfectly well defined to the last, and saw the line becoming narrower, and the curves becoming sharper, without any distortion or prolongation of the limbs.[…]
