Dear Sir,

The difficulty with regard to the money received by the Observatory from the Bache Fund, which I mentioned in my letter to you of last August, has just been removed, and there is now nothing to hinder the appearance of the new publications of the Observatory. Your "Photometric Researches" will form Part I of Volume IX of the Annals of the Observatory, and will be paid for from the Sturgis Fund.

I enclose with this a sample of the double title-page of Vol. IV, Part I, which was printed from the Sturgis Fund. I presume that the precedent thus set is now to be followed as was done in the case of Vol. V, also a Sturgis publication. In Vol. VII the double title page was not used, perhaps because no name but that of Prof. W. C. Bond was required in the title. The Sturgis Fund was given simply for the publication of the "transactions" of the Observatory, (instead of "the astronomical observations of the principal lesson," in the terms of the Quincy donation) and usage does not seem to require any mention of the Director in the title-page of a Sturgis publication.

I also enclose a list of about two hundred institutions and forums to whom the Annals of the Observatory are sent. I take the list pretty much as I find it, but I presume it requires some alteration, especially in the way of additions. You will of course use your own discretion in distributing your work in the name of
