Published in: C. Smallwood, September 1869, "On the Partial Eclipse of the Sun, August 7th, 1869", Canadian Naturalist, vol. IV, no. 3, pp. 249-256, photograph: opp. p. 249
From p. 256:
In reference to the twelve photographs made by Mr. Notman, there is an error in time of three minutes compared with Montreal mean time, at the Observatory. Thus for 5h 18m. Read 5 hours 15 minutes, and so on, making a deduction in every case of three minutes from the time noted in the accompanying photographs; in other respects they are a most faithful and reliable delineation of the various phases of the eclipse.
[In the accompanying photographs, the light part represents the sun, the dark projections upon its disk the portion of the moon showing the amount of the eclipse at the time marked underneath each.]
