This theatre is warmed in cold weather by steam, which, coming in covered and concealed tubes from the lower part of the house, circulates in a large semicircular copper tube eight inches in diameter and above sixty feet long, which is concealed under the rising seats of the pit. The repository already contains a considerable number of specimens of new and useful mechanical contrivances. The chemical laboratory, in which there is provision made for placing and using no less than sixteen furnaces of different kinds at the same time, is quite finished. All the workshops of the Institution are now quite finished, and they have been furnished with the most complete sets of tools that could be procured, and several excellent workmen are now employed in them; and a great variety of useful articles designed as models of imitation have already been manufactured in the house, and are ready to be delivered to any of the proprietors or subscribers to the Institution who may be disposed to purchase them. The great kitchen at the house of the Institution has been furnished, and now contains a variety of new and useful utensils and implements of cookery, many of which are in daily use, and others (which are not) are so exposed to view as to be easily understood and their merit appreciated. He then gives an account of each room. The present lower library was divided into two rooms, the first for foreign newspapers, the other for books. Over these rooms was the second lecture room, which at some future period was to become the library. It will be useful for occasional lectures, and for exhibiting new experiments, and for the meetings of the committees. The conversation room has been furnished, and everything has been prepared for its being used as a coffee room. It is now set apart for the daily papers. The proprietors since June had increased 16, the life subscribers 16, and annual subscribers 122. All the new works to be done and every demand would amount to 3,900_l._ The balance at the banks and the debts to the Institution came to 8,100_l._ The Institution has been completed without any debt, and the annual income is quite sufficient to defray all the expenses of keeping it up. He ended thus: The Royal Institution of Great Britain may therefore be considered as finished and freely established. That it may long continue to flourish is no doubt the ardent wish of those who are connected with it, and also of all those who are acquainted with the principles on which it is founded, and who know how powerfully it must contribute to the general diffusion of an active spirit of inquiry and useful improvement among all the ranks of society. Such was Count Rumford’s favourable statement when he was about to take leave for a time, and, as it proved, for ever, of the Institution he had founded.
