_7mo._ Proprietors will have the privilege of recommending persons for admittance to the philosophical lectures and experiments, and the persons so recommended will be admitted in all cases where there shall be room for their accommodation, provided that the persons so admitted conform to the rules and regulations which will be established by the managers for the preservation of order and decorum within the walls of the Institution. _8vo._ No more than _forty per cent._ of the sum subscribed by each proprietor will be wanted immediately, and the remainder may be furnished in three equal payments at the expiration of the three next succeeding half-years; but it will be in the option of proprietors to pay the whole sum of fifty guineas at once if they should prefer doing it. PRIVILEGES OF THE SUBSCRIBERS FOR LIFE. Each subscriber of this class will receive _one_ ticket for life, but not transferable, of free admission into the Institution, and into every part of it, together with _one_ other ticket for life, but not transferable, of free admission to all public philosophical lectures and experiments. PRIVILEGES OF ANNUAL SUBSCRIBERS. Each annual subscriber will receive _one_ ticket for one year, but not transferable, of admission into the Institution, and into every part of it; as also _one_ ticket for one year, but not transferable, of admission to all the public philosophical lectures and experiments. Subscribers of this class will, moreover, have a right of becoming subscribers for life, on paying at any time within the year for which they subscribe an additional sum of eight guineas. PRIVILEGES THAT ARE COMMON TO SUBSCRIBERS OF ALL DENOMINATIONS. _1mo._ Subscribers for life and annual subscribers, as well as the proprietors of the Institution, will be entitled to have copies or drawings (made at their own expense, however) of any of the models in the repository, and this even when such copies are designed for the use of their friends, as well as when they are wanted for their own private use; and for their better and more speedy accommodation workshops will be prepared, and workmen provided under the direction of the managers, for executing such work properly and at reasonable prices. And, to prevent mistakes, all copies or drawings that shall be made of the machines, models, and plans lodged in the repository of the Institution will be examined by persons appointed for that purpose, and marked with a seal or stamp of the Institution.
