ARCHITECTURAL SOCIETY. 



Report of the Committee, read at tlie Annual General Meeting held the ith 

 of June, 1839, at the Society's Room, No. 35, Lincoln's Inn Fields. 



Gentlemen, — In making this their annual report, the committee have the 

 pleasure of appearing before the society under circumstances which they 

 venture to think fully justify them in congratulating the members on the 

 very satisfactory condition of the society generally. During the past year 

 many important sulijeets have been brought under consideration. In the 

 early part of it, a proposition was made for the junction of this society with 

 the Institute of British Architects. The proposition itself originated with 

 this society, which is the liest evidence of their inclination to make a com- 

 mon cause for common objects. The negotiation, however, the committee 

 regret to say, failed, in consequence of its lieing ascertained that tlie Insti- 

 tute had hound themselves by bye-laws of so exclusive a natiu'e, rendered 

 imperative by the cliarter, that, in the opinion of counsel, they could not be 

 relaxed ; these bye-laws prevented this society from seciu-ing any control 

 over the disposition of the funds and property which they were called upon 

 to give uj), and were otherwise objectionable. Upon a full and careful 

 consideration of the whole matter, this society therefore negatived the propo- 

 sitions ; they are not aware, however, that they have been losers by this 

 determiuation, for though some of their members left them and joined the 

 Institute, the number is not so great as has been stated, and the secession 

 has been more than filled up by the accession of other members, amongst 

 whom they are happy to reckon some of the most respectable senior members 

 of the profession. This discussion, however, they are happy to state, has 

 been most useful in its results, because the Institute has been thereby led to 

 create a class of student members in connexion with their society. This class 

 they had previously entirely overlooked, though it is obvious that one of the 

 best and most certain means of raising the profession of architecture to its 

 fair place amongst the fine arts of this country, is by encouraging and edu- 

 cating the junior members. 



The next subject to wliich they think it necessary to refer, is one of entu'e 

 congratulation in the acceptance of the office of jiresident by Mr. Tite : to 

 tliis gentleman the committee feel bound to tender their best thanks for the 

 devotion of a considerable portion of his valuable tune, for a liberal donation, 

 and for the present of some valuable and costly books. 



The committee have also to state that the donations to the society have 

 been on the increase dming the present session ; not merely has the library 

 and museum been extended, but the funds of the society have also been mucli 

 benefitted, and the committee are happy to state, that although they have 

 this session had to meet many extra heavy expenccs, the funds are at the 

 present time in a very satisfactoiy state. It is not necessary to introduce 

 a balance sheet of the accounts in the present report, but any of the members 

 who may wish to inquire more particularly into this subject, may receive any 

 information they require on application to the treasurer, Mr. George Mair. 



The introduction of lectures at the evening meetings forms a new featiu'e 

 in the proceedings of the society, and the committee feel that it is a measure 

 wliich has met with the approbation of the members generally ; with this 

 conviction the connnittee have it in contemplation to make similar arrange- 

 ments for the ensuing season, and by so doing they hope gi'eatly to extend 

 the advantages the society previously otTered. 



The prizes for this year have been adjudged by the society as follows : viz. 



To Mr. George Adam Bmn, of George Place, Hammersmith, student 

 member, for the best essay on the Ionic order. 



To Mr. George B. Wilhams, Penny Fields, Poplar, for the best measured 

 drawing of St. Mark's Chapel, South Audley Street. 



The only remaining subject that the committee tliink it necessary to advert 

 to, is with reference to the student mendiers, ami they have to regret that 

 they have not availed themselves of all the advantages this society offers. 

 In consequence of this circumstance they have been obliged to withhold two 

 of the prizes usually given ; viz. that for original design, and that given by 

 the treasurer fgr sketching from subjects proposed at each meeting. 



One of the main oljjeels for whicli the Architectural Society was founded, 

 was for the purpose of aftbrding facilities of study, as well for its student 

 members, as for nuitual intercourse among themselves ; and in giving the 

 students those facilities, the society has emleavoured to offer every induce- 

 ment in its power, not merely to excite study, but to create emulation, and 

 to call forth latent talent amongst its j\niior members. 



Tlie committee feel it their duly to call attention to these circumstances, 

 knowing of themselves the benefits that are to he derived ft'om a proper 

 participation in the opportunities of study thus offered. 



It now only remains for the committee to express the thanks of the society 

 to the visitors who have honoiu-ed thorn with their company at their several 

 meetings, and also to the gentlemen connected with the press, to whom they 

 feel indebted for the kind manner in which they have been pleased to notice 

 their proceedings. 



In conclusion, gentlemen, the committee tnist that the ensuing session 

 may be as generally successful as tlie past, and that they may be able to pro- 

 cure, with increased satisfaction to themselves, increased motives for your 

 attendance at theii- meetings. 



They beg to assure you it will he their study to cany out the objects for 

 which the society was formed, and they hope in so doing not only to deserve, 

 but to receive, yoiu- approbation and support.

The following papers were read : — 



" On tlie motion of the Blood," by J. Carson, JI.D. After referring to his 

 paper contained in the Philosophical Transactions for 1820, relative to the 

 influence of the elasticity of the lungs as a power contributing to the eff'ectual 

 expansion of the heart, and promoting the motion of the blood in the veins, 

 the author states that his object in tliis paper is to explain more fully the 

 mode ill which these effects are produced, and to corroborate by additional 

 facts and olisen-ations the arguments adduced in its support. He endeavours, 

 from a review of the circumstances under which the veins are placed, to show 

 the inconclusively of the olijections which have been inged by various phy- 

 siologists against his and the late Sir David Barry's tlieoiy of suction : namely, 

 that the sides of a phant vessel, when a force of suction is applied, will col- 

 lapse and an-est the further transmission of fluid through that channel. The 

 considerations which he deems adequate to give efficacy to the power of suc- 

 tion in the veins of a living animal are, first, the position of the veins by 

 which, though pliant vessels, they acqiure in some degree the properties of 

 rigid tubes ; secondly, the immersion of the venous blood in a medium of a 

 specific gravity at least equal to its own ; third, the constant introduction of 

 recreinentitious matter iuto the venous system at its capillary extremities, by 

 wliich the volume of venous blood is increased, audits motion urged onwards, 

 to the heart in distended vessels ; and lastly, the gravity of the fluid itself, 

 creating an outward pressm-e at all paits of the veins below the highest level 

 of the venous system. The author illustrates bis positions by the different 

 quantities of blood which are found to flow from the divided vessels of an ox, 

 according to the different modes in which the animal is slaughtered. 



2. Account of Experiments on Iron-built Ships, instituted for the purpose 

 of discovering a Correction for the Deviation of the Compass produced by the 

 Iron of the Ships, by G. Biddell, Esq., A.M. 



In this paper the problem of the deviation of a sliip's compass, arising from 

 the influence of the iron in the sliip, more particularly in iron-built ships, is 

 fully investigated ; and the ]irinciiiles on which the correction for this de- 

 pends having been determined, practical methods for neutrahzing the deviating 

 forces are deduced and illustrated liy experimental application. The author 

 states that, for the purpose of ascertaining the laws of the deviation of the 

 compass in the iron-built steam-ship the Rainbow, four stations were selected 

 in that vessel, about foitr feet above the deck, and at these the deviations of 

 the horizontal compasses were determined in the various positions of the 

 ship's head. All these stations were in the vertical plane, passing through 

 the ship's keel, three being in the after part of the slii|) and one near the 

 bow. Olisenatious were also made for determining the horizontal intensify 

 at each of these stations. The deviations of dipping needles at three of these 

 stations were also determined, wlien the plane of vibration coincided with 

 that of the ship's keel, and also when at right angles to it. .\fter describing 

 tlie particular method of observing I'cudered necessary by the nature of the 

 vessel and the circumstances of her position, the author gives the disturbance 

 of the horizontal compass at the four stations deduced from the observations. 

 The most striking feature in these results, is the very great apparent change 

 in the direction of the ship's head, as indicated by the compass nearest the 

 stern, coiTCsponding to a small real change in one particular position, the 

 foriiior change being 97", whereas the latter was only 'ly, and the small amount 

 of disturbance iuchcated by the comiiass near the bow. After giving the obser- 

 vations for the determiuation of the influence of the ship on the horizontal 

 intensity of a needle suspended at each of the stations, in four different jiosi- 

 fions of the ship's head, and the disturbances of the dipping needle at three of
