Where no reference is given to the Transactions the paper has so far appeared only in the “Proceedings.” XXIV LIBKARY RULES, 1. The Library is open for consultation, and for the issue and return of books, daily from 10 a.m. to 6 p.m. (Saturdays 10 a.m. to 2 pm.); and in the evenings of those days on which the Chemical Society meets. 2. Fellows are not allowed to have on loan more than six volurnes at a time, without; special permission from the Librarian. 3. All Journals, Dictionaries, and Pamphlets of which there are not duplicate copies, and certain early Chemical and other Books distinguished in the Library Catalogue by a star, belong to the Reference Library, and are not for general circulation.Fellows desiring to borrow books from the Reference Library must make a special application in writing to the Librarian, undertaking to bear all risks of transit, &c., and to return the volumes within one month; the Librarian may then, at his discretion, issue such books. This regulation does not apply, however, to volumes of Periodicals of whicli no duplicate copies exist in the Library. 4. A book may not be taken out of the Library until one month after it has been received. 5. Books must not be removed from the Library until a voucher for them has been signed and delivered to the Librarian.6. Bo3ks are issued either to the Fellow desiring tha loan, or to a person bringing a written order from him. In either case a receipt must be given on the form provided. When a Fellow desires a book or books to be sent to him, he must send to the Librarian a written order, and pay the whole cost of carriage. All books borrowed by Fellows shall be at the risk of the borrower from the moment they are issued or despatched by the Librarian, and until they are returned to him. 7. Books may not be sent out of the Uuitcd Kingdom, 8. Books which have been bespoken shall circulate in the order xx v of application. 9. Fellows shall be at liberty to retain a book one calendar month, unless, at the expiration of a fortnight, notice is received that the book is required by another Fellow, in which case it must be returned at once.Single parts of journals may not be retained longer than one week. 10. The names of Fellows borrowing books shall be entered by the Librarian, or Officer in attendance, in a book kept for that purpose. When a Fellow returns a book, his voucher shall he given to him, and a record of the return duly made. 11. In the case of Fellows returning books by messenger or public conveyance, the voucher shall be returned by the Librarian through the post. 12. Fellows retaining books longer than the time specified, or neglecting toreturn them when demanded, shall forfeit the right to borrow books from the Library until the volume or volumes be returned.13. Fellows to whom books have been issued shall be held responsible for their preservation from injury; and if any book when returned is found to have been damaged, the Council may order that it be repaired or replaced at the expense of the borrower. In the event of any book being lost, or being detained after appli. cation has been made for its return, the Council may replace, at the cost of the borrower, the volume or volumes so lost or detained. This rule shall also apply to single parts of current periodicals. 14. For the purpose of revision and cleaning, the Library shall be closed for a fortnight in August of each year; before which time all books must be returned, unless special permission has been previously obtained from the Librarian.In the event of any book not being returned on such occasion, the Council may replace it at the cost of the borrower. 15. No persons other than Fellows of the Society have the privilege of using the Library, except upon a written introduction from a Fellow, with whom rests the responsibility for all books consulted by the person introduced. Such introduction shall be valid for one occasion only. XXVl ADDITIONS TO THE LTBRARY DURING THE YEAR 1905. Abegg, R. See Guldberg, C. hl. -See Handbiich der anorganischen Chemie. Allen, Alfred H.
