THE CIVIL ENGINEER AND ARCHITECTS JOURNAL. 



Sept. 



16. Lord Cornwallis receivinf; the Sons of Tippoo as hostages. 

 In the large compartment on the west wall : — 



17. Trafalgar ; the Death of Nelson. 



In the corresponding compartment on the east wall :— 



18. Waterloo; the meeting of Wellinglon and Blucher. 



The Queen's Robing Room, 

 Containing compartments of various dimensions, adapted for painting and 

 other decorations. 



Your Committee, inflnenced by the considerations before expressed as 

 to the expediency of varying the character of the decorations proposed, 

 were of opinion that a series of paintings, and other works of art, illustrat- 

 ing the legend of King Arthur, would be appropriate in this locality ; and 

 your Committee unanimously agreed to recommend to tlie Commission, 

 that the execution and entire superintendence of such decorations shoulii 

 be entrusted to Mr. Dyce, who has already executed a fresco in the House 

 of Lords. 



The Guard Room, 

 Containing two compartments, each measuring 12 feet wide by 8 feet 

 high. 



Your Committee conceived that these compartments might be filled with 

 the following subjects; — 



1. Young Talbot defending his Father in Battle. 



2. Isabella Douglas barring the Door with her Arm to protect James I. 

 of Scotland. 



The Lobby of the Guard Room, 

 Containing one compartment, measuring 14 feet 5 inches high, to the point 

 of the Gothic arch, by 10 feet wide. For this locality your Committee 

 selected the subject of St. Edmund the Martyr slain by the Danes. 



The Norman Porch, 

 Containing two compartments, each measuring 18 feet 2 inches high, to the 

 point of the Gothic arch, by 10 feet 10 inches wide. 



It was the opinion of your Committee that these compartments would be 

 appropriately filled with the two following subjects: — 



1. Canute reproving his Courtiers. 



2. Queen Elizabeth on the sea-side after the defeat of the Spanish 

 Armada. 



Your Committee conceived that the subjects in all the localities men- 

 tioned should be accompanied with inscriptions, and, in some instances, 

 with appropriate mottoes; that in the last named subject the motto might 

 be "AiBavitDeus et dissipantur," and in the subject of Canute, "Nemo 

 Doroinus nisi Deus." 



Thi Peers' and Commons' Refreshment Rooms. 

 The compartments in the two Rooms belonging to the Peers might he 

 appropriated to views of places of the chief importance within the United 

 Kingdom. The compartments in the other Rooms to views of the most 

 remarkable places in India and the Colonial possessions of the Crown. 

 Space might also be found for subjects connected with rural scenery, the 

 Harvest, the Chase, &c. 



The Painted Chamber, being the Hall of Conference between the 



TWO Houses, 

 Contains 13 compartments adapted for painting : two on the east side, 

 measuring 10 feet 4 inches high by 7 feet 4 inches wide : five on the west 

 side, ihe centre compartment measuring 10 feet 4 inches high by 16 feet 

 4 inches wide ; two compartments next the corners measuring 10 feet 4 

 inches high by 9 feet wide, and two over the doors, measuring 4 feet 6 in- 

 ches high by G feet 9 inches wide. Three on the north side, the centre 

 compartment measuring 10 feet 4 inches high by 14 feet 3 inches wide, 

 and two smaller compartments, each measuring 7 feet 10 inches high by 

 4 feet 8 inches wide : and three on the south side corresponding with those 

 on the north side. 



Your Committee conceived that the subjects for painting in this locality 

 might have reference to the arquisilion of the countries, colonies, and im- 

 portant places constituting the British Empire ; and that the following sub- 

 jects would be appropriate : — 



In the centre compartment on the west side, 1. The Marriage of Strong- 

 bow and Eva, daughter of Dermot, King of Leinster. 



In the centre compartment on the south side, 2. Edward I. presenting 

 his infant Son to the Welsh as their Prince. 



In the centre compartment on the north side, 3. James VI. of Scotland 

 receiving the news of the Death of Queen Elizabeth ; or Setting out for 

 England as James I. 



In the two compartments, next the corners, on the west side :— 



4. Lord Clive in the Battle of Plassy. 



5. Penn's Treaty with the American Indians. 

 In the two compartments on the east side; — 



6. The Colonization of .4.ustralia. 



7. The Treaty of Nankin. 



In the two compartments over the doors on the west side : — 



8. 9, Incidents illustrating the Voyages to the North and South Poles. 

 In the small compartments on the south side ; — 



10,11. Incidents relating to the acquisition of Mauritius and the Cape 

 of Good Hope. 



In the two small compartments on the north side: — 



12. Sir George Rooke planting the Standard of England on Gibraltar, j 



13. The Surrender of Malta. 



The entrance from Old Palace Yard is also intended to conlain soma 

 compartnjents for painting, but your Committee conceived that it would be 

 proper to postpone the consideration of subjects for this locality as it is not 

 yet certain whether paintings can be seen in it to suflicient advantage. 



With regard to the technical method in which the paintings proposed 

 should be executed, your Committee, although not prepared to offer a 

 general recommendation on this subject, were of opinion thaV the pictures 

 in the three corridors leading from the Central Hall, and the pictures in 

 the Refreshment Rooms should he painted in oil ; and that the Queen's 

 Robing Itonm, .St. Stephen's Hall, and the Royal Gallery should be painted 

 in fresco. The representations of the four Patron Saints, from their size 

 and situation, might be advantageously executed in Mosaic (like the four 

 Evangelists in the pendeutives of the Cupola of St. Peter's), thus giving 

 an opportunity for the introduction into England of an art highly valued in 

 other times and countries. 



Your Commitlee have further to observe that moveable oil paintings, not 

 coming within the general plan proposed, might be placed in Committee 

 Booms and in other parts of the building.

" On Anemometers and Resolving Scales." By Captain CocKBCRN. 



The advantage of a correct statement of the winds at sea has, for some 

 years, been most apparent to me. Since the introduction into the naval 

 service of a certain formula for stating the force of the wind, represented 

 by numbers from 1 to 12, according to the sail carried and speed of a well- 

 conditioned man-of-war, and this depending upon the opinion of the officer 

 of the watch, the notations are as various as the opinions on such a subject 

 must be ; and I certainly have seen great discrepancies noted on the ship's 

 log-book. This evident evil is the immediate cause of ray attempting to 

 make an anemometer which might correct it. The concive form of the 

 revolving wings of this instrument was taken from a paper read on the 

 subject last meeting. The concave surface holding one-third more wind 

 than the convex, by theory it would revolve one-third as fast as Ihe wind; 

 consequently, three times the distance described by a cup in a revolutioa 

 would be the velocity of the wind in the time occupied ; this is supposing 

 the form of the cup to be a perfect hemisphere, and no friciion either in the 

 mechanism of the instrument or in the air; but as there must be friction 

 and resistance from both these causes, this necessarily involves a correction, 

 which must be determined by experiment, in order to establish the value 

 of the revolutions. From the experiments I have made on the lop of rail- 

 way carriages and in steam boats, the correction for the large-sized cups 

 is '5 or J. I do not by any means consider this to be decisive ; the results 

 have been various, from the unsteadiness of the wind during the trials, and 

 from the mass of air carried along by the moving body : this will n)ake the 

 multiple 3 5 instead of 3. I am persuaded, also, that a dilferent multiple 

 will be required at moderate and at great velocities ; but I have not been 

 able to ascertain it. This value depends also upon the circumference of 

 the circle described by the cups, their form, and weight. I shall not enter 

 into the relative advantages of the forms and sizes of those I have had 

 made : the diameters of each are, from centre to centre of the cups, includ- 

 ing the arms, 12, 10, and 8 inches. Those simple multiplying wheels I 

 have used may be substituted by the plan adopted for gas-meters, which I 

 think preferable. 



" On Changes in the Position of the Transit Instrument occasioned by the 

 Temjierature of the Earth, from the Observations of Prof. C. P. Smyth, of 

 Edinburgh." By Prof Powell. 



Mr. Mallet, in an address to the Geological Society of Dublin, mentioned 

 that .Sir W. R. Hamilton had noticed certain cliangcs of level in the transit 

 instruments at his observatories; and that Dr. Kobinson bad also found such 

 a change both in the general level of the observatory and also a motion in 

 azimuth, recurring at annual periods, and apparently depending on the 

 temperature of the earth ; — but no details of such observations were given. 

 Prof. C. P. Smyth has pursued such observations in detail at the observa- 

 tory on the Calton Hill, Edinburgh, aided by the thermometric determina- 

 tions of the changes of the temperature in the subjacent soil, made under 

 the direction of Prof. Forbes, by thermometers sunk in the ground. The 

 data he used were those obtained at depths of 5 feet, 3 feet, and in contact 

 with the pier of the observatory. The movements, both in the level of the 

 transit, and also in azimuth, are laid down graphically in curves, and ex- 

 hibit a remarkable agreement with the changes in temperature, the westera 

 end of the level being highest in summer, and the deviation of the west end 

 of the transit axis being greatest loumrds the south in winter. 



" On the Coloured Glass employed in Glazing the new Pain House in 

 the Royal Botanic Garden at Kew." By R. Hunt. 



It has been found that plants growing in stove houses often suffer from 

 the scorching influence of the solar rays, and great expense is frequently 

 incurred in fixing blinds to cut olf this destructive calorific influence. 

 From the enormous size of the new Palm House at Kew, it would be 

 almost impracticable to adopt any system of shades which should be
