III. That a particular room be allotted for the persons so admitted, in which they may sit, and read or write, without interruption, during the time the Museum is kept open: that a proper officer do constantly attend in the said room, so long as any such person or persons shall be there: and for the greater ease and convenience of the said persons, as well as security of the collection, it is expected, that notice be given in writing the day before, by each person, to the said officer, what book or manuscript he will be desirous of perusing the following day; which book or manuscript on such request, will be lodged in some convenient place in the said room, and will from thence be delivered to him by the officer of the said room: excepting however some books or manuscripts of great value, or very liable to be damaged, and on that account judged by the Trustees not fit to be removed out of the library to which they belong; without particular leave obtained, of the Trustees, in a general meeting, or a standing Committee, for that purpose; a catalogue whereof will be kept by the officer of the reading room. IV. That such persons be allowed to take one or more extracts from any printed book or manuscript; and that either of the officers of the department to which such printed book or manuscript belongs, be at liberty to do it for them, upon such terms, as shall be agreed on between them. V. That the transcriber do not lay the paper, on which he writes, upon any part of the book, or manuscript, he is using. VI. That no whole manuscript, nor the greater part of any, be transcribed, without leave from the Trustees, in a general meeting, or standing Committee. VII. That every person so intrusted with the use of any book, or manuscript, return the same to the officer attending, before he leaves the room. VIII. That if any person engaged in a work of learning, have occasion to make a drawing of any thing contained in the department of natural and artificial productions, or to examine it more carefully than can be done in the common way of viewing the Museum; he is to apply to the Trustees in a general meeting, or the standing Committee, for particular leave for that purpose: it not being thought proper, unless in particular cases, to have them removed from their places, and out of the sight of the officer who has the care of them.
