Annual Report of the Board of Mana.qers of the Eranklin ~stitute for the Year 1865. In accordance with the By-Laws, the Board of 5{anagers presents its Annual Report of the condition of the affairs of tile Institute. Soon after the beginning of the last year, an examination was made of the present Institute building, and the advantages and drawbacks attending a change of location were fully discussed. From the considerations thus made apparent, it was determined to execute extensive alterations and repairs, by which the present building might be rendered adequate to the purposes of the Institute, and attractive to those whom it was designed to accommodate. The execution of these alterations and improvements was placed in the charge of a committee, and with the beginning of the summer, when the building was less used. than at other seasons, this work was commenced. Notwithstanding the unprecedented difficulty in securing skilled labor which has marked the last season, these improvements have progressed in a satisfactory manner, and may be now said to approach completion, and have cost about ~;7000. The work accomplished may be briefly expressed as follows: A substantial and permanent slate roof has been put upon the whole building. The library and reading room has been enlarged so as to afford additional case room nearly equal to its whole original capacity. This change was demanded by the condition of the books, which were placed two deep in nearly all the cases, with additional crowding, which rendered any complete systematic arrangement out of the question. Large additions of new and important works have been made to the contents of the library, and the whole arranged in a convenient and accessible manner. The reading room and adjacent offices have been entirely refurnished, and rendered not only comfortable but highly attractive in their appearance and accommodations. The lecture room has received most extensive alterations; each of the ascending platforms constituting the floor surface have been wictened to secure comfort to the audience, and furnished with cane-seated chairs in place of the wooden benches formerly in use. i newlecture table, containing a large leaden pneumatic cistern properly furnished with inlet and outlet pipes, has likewise been added, and the space in rear of this increased to a depth of twenty feet, by which means optical experiments and illustrations of other subjects by optical apparatus may be developed with a facility and success equalled nowhere in this city. The whole arrangement for lighting this room has been reconstructed and proves itself both efficient and admirably under control. The laboratories adjoining the lecture room have been thoroughly repaired, furnished with new cases, with gas and water supply, and with an evaporating closet so as to answer efficiently to the demands of modern experimentation.

Lastly, the cellars of the building have been cleaned, opened, and repaired, and supplied with two furnaces of the most improved construction for heating the lecture and reading rooms. By the report of the Treasurer it will be seen that the receipts and payments during the past year have been as follows : Balance in the Treasury, J a n u a r y 1, 1865, :Receipts during the year,

It is to be recommended to all the members and friends of the Institute to secure, if possible, the disposal of the entire stock of the Institute, by which its permanent success would be placed upon a secure basis. It is also to be remembered by holders of stock, that they not onlyenjoy the advantages of the Institute at a cheaper rate than members, but have beside an ownership in the Institute. The holder of ten shares enjoys likewise all the privileges of membership, without the payment of any annual fee, and may besides bequeath this privilege to his survivors or assign it to another.
