It was immediately i-ecognized that here was a new opportunity for determining the solar parallax and that the determination must be made at once or left alone for thirty years, for a comparativeh' favorable opposition was due in U)00 and no more good ones till 1930 and 1937. At the meeting of the permanent connnittee which directs the nuUving of the astrographic chart and catalogue of the whole sky it was resolved to invite a great coopera- tion of observatories to make a combined onslaught on the j)i'oblem. The suggestion was readily taken up, with an alacrity, indeed, which might almost have suggested that the observatoi'ies concerned had nothing to do and were glad of a job, an imputation which is innnedi-.
