22. 27. 42'8. Geometrical contact. Scarcely visible through, cloud. Very

 out a coloured glass. 



22. 43. 42'5. A guess at the time of transit of the center of the planet 

 over the Sun's limb. Image faint, but brighter than 

 before. Without a coloured glass. 



22. 58. 19'2. External contact. Without a coloured glass. Image bright, 

 through haze. I think I got it fairly exact.
