Excerpt from Report on the Preparations For, and Observations Of, the Transit of Venus: As Seen at Roorkee and Lahore on December 8, 1874It will be seen that I have departed in one point from sir george airy's instructions. I have left all the equations with seconds of space' as a unit, instead of taking the last step, and making the unit a second of observed time. In all the calculations connected with the observations near contact, I have felt that except in the contacts themselves, the pro bable error of observed time was of no importance, and that that of space alone affected the result in the case of the alt-azimuth Observations of course it was the errors in space which were sought. Though I had at one time intended also exhibiting these results here as proposed b sir G. Airy, I have finally left them, for uniformity, as they stand in my papers.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
