The Committee, not unmindful of the advantages and encouragement the

 ference to.'and the use of, the Society's library and documents at all times 

 of the dav, without any restriction ; and flic Committee trust that tliis ar-

 elicited from the attendance of the visitors, that the Architectural Society may 

 have the gratification of finding that the meetings of this session may lie 

 as advantageously and as satisfactorily concluded as those of its former 

 sessions. 



\9fh Nov. — William Tite, Esi/., President in the Chair. 

 Mr. Blyth read a paper on commemorative monuments. 

 The President announced that Mr. John Blyth (Vice-President) had com- 

 municated his intention to give a prize of the value of live guineas 

 for the best drawing of a plaster east of the human figure, from some sjieci- 

 men in the possession of the Society. The prize to he awanled at the close 

 of the session, and to be described accordingly. 



At the solicitation of the student members, the President announced the 

 subjects which had been ; selected for the prizes, and the resolutions 

 passed last session, assigning the qualifications for the competitors for the 

 prizes were referred to, and read as follows: — "That no studiMit shall be 

 allowed to compete for either of the prizes awarded by the society, who shall 

 have completed his articles, and that the society only award the prizes to 

 students under articles." 



Also, " That the same regulation do apjily to any private jirize, which 

 may be offered for the further encouragement of the class of student incm- 

 bers." 



3rd December, 1839. — William Tite, A'vy., President, in the Chair. 

 The President gave notice that the subject selected for Mr. lilyfh's prize 

 was the figure of " the Atlas." The figure to be drawn IS inches high, and to 

 he shaded in lines with pencil or ink. 



The meeting was then favoured by a very interesting and instructive lec- 

 ture hy Mr. Ilemmiug, the subject of which was "Iron." * 

 llth Decemlter, 1839. — William Tite, Esq., President, in the chair. 

 The President gave notice that the Hon. C. Cavendish had given his assent 

 for the students to measure the colonnade of Biirlingtou House; and that,

The President announced a donation from the .\rcliutcctural Society of 

 Berlin of the third volume of the Architects' Album, published by that 

 body. 



Mr. Addanis delivered a lecture "On the strength of beams to resist pres- 

 sure and impact." He referred to iron as well as wood ; and in the course 

 of the lecture gave some excellent tables, whereby an easy cakulation 

 might be made as to the weight any iron beam would carry. 



Mr. Pocock explained to the meeting a new material be had manufactured 

 for the purpose of roofing in lieii of slating, &c., a specimen of which was 

 lying upon the table. 



STEAM NAVIGATION. 



THE 'CVCLOP.S' STEAM ENGINE. 



On- Friday the Kith of December, this splendid vessel left her moorings at 

 Blaekwall, for a trial trip down the river, and to proceed to Shecrness to 

 t.ake in her guns and equipments. This being the largest steam frigate in the 

 world excited much attention, and thronglioiit her passage down the river, 

 WHS an object of great curiosity and admiration. 



The trial was made under the directions of the Lords of the Admiralty and 

 their officers, several of whom \\ere on board, viz.. Sir C. Adam, the Secre- 

 tary of tlie Admiralty .\lr. Moore O'Pcrrall, Sir E. Parry, Sir William Symonds, 

 Captain Nutt, Captain Austin, fic. &-C. 



ller performance was most excellent, the speed was found to be about 10 

 knots, or 11. I miles, her engines working 21 strokes; and it was universally 

 remarked that there was an entire absence of the unpleasant tremulous motion 

 so generally found in otiier steamers. 



After proceeding close to the Nore Light, she turned and met the " Fear- 

 less" Admiralty steamer, which accompanied her down, and their Lordships 

 embarked in tiiat vessel to return to Woolwich, while the "Cyclops" pro- 

 ceeded up the Medway, and made fast to the buoy ofT Shcerness Dock-yard. 

 This vessel was ]ilanned by Sir WilUam Symonds, and built under his im- 

 mediate supeiinteiidanee at Pembroke dock-yard; she combines in a most 

 eminent degree the qualities of both sailing and steaming, together with such 

 improvements as have suggested themselves to her designer from the exiieri- 

 ence of the " Gorgon." 



She is propelled by two engines of ICO horse power each, made by Meiirs. 

 J. & S. Seaward and Capel, on the new princijile adopted by them, by which 

 they dispense with the large cast-iron side frames and sway beams, the cross 

 heads, side rods, &c., &e., and thus bring the weights of these engines to 70 

 tons less than they would have been, had they been made on the common 

 beam principle; and thereby also effect a very important saving of sjiace in 

 the length of the engine room. These engines are fitted with a contrivance 

 (which is protected by patent) for warming the feed water on its passage to 

 the boiler, by causing it to jiass through a number of cojipcr jiijics around 

 which the spent steam from the cylinder circulates, on its way to the con- 

 denser ; by which means the teniperature of the feed water is elevated about 

 60 degrees' above the usual temperature, at which it enters a boiler, and a 

 saving effected in the consumption of fuel of seven per cent. 



There are four copjier boilers for supplying the above with steam, made 

 entirely of copper, and ]ilaced in pairs, hack to back, with a fore and aft stoke 

 hole; these boilers are clothed on the system first used by Messrs. J. and S. 

 Seaward and Capel, and since introduced into the navy for Her Majesty's 

 steam ships, for the jirevcntion of the radiation of heat ; the advantages of 

 which were evident in the surprising coolness of the engine room. A baro- 

 meter placed against the side of the boilers only rose to 68", and another in 

 the stoke-hole to only 72' . 



The boilers are fitted with a patent apparatus for detecting and indicating 

 the state of saltness of the water in the boiler; and also with a receiver and 

 apparatus for blowing out, when the time for that operation has arrived; by 

 means of which all danger from salting the boiler, or blowing out the wafer 

 too low, is entirely obviated ; and the boiler may be worked as long with salt 

 water as with fresh. 



There are coal-boxes placed on each side of the vessel the whole length of 

 the engine room, and holding when full about 450 tons of coals. The con- 

 sumption of fuel by actual weight (the coals being weighed during the trial) 

 was 17 cwt. per hour, equal to 6 lbs. of coal per horse per hour. 



The " Cyclops" is commissioned by Post Captain Austin, l.nte of the Medea, 

 being the only steam frigate in the navy besides the " Gorgon," of that rank. 

 Her engine room crew will consist of four engineers, twelve stokers, and four 

 coal trimmers. — The actual number of hands including officers and a lieuten- 

 ant's party of marines, will be two hundred and ten men. 

 Jler dimensions are as follows : —

 The armament of the "Cyclops" will consist of — on the upper deck two 98
