■ u' ^'f«'c»< Merchant Vessel in the Irorto.— This rnaKiiiHcent ship arrived 

 '" 4"' '"ersey last monlh ou her first trip across the Atlaiilic. She is in- 

 tended to take her station as one of the packet-ships between that port and 

 New York. She is 188 feel long between perpendiculars, 19G feet from 

 the stem to the talTrail, 42 feet extreme breadth of beam, 29 feet deep, and 

 IS 1,81S 15-95lhs tons, carpenfer's measurement, or 1,511 31-95liis, Go- 

 Ternment measurement. It is estimated that she will stow 5,000 bales of 

 cotton, or 3,000 tons of measurement goods. She has three decks, the 

 same as a frigate, the upper one being as substantial, in proportion, as 

 either of the others. — Lii-erpool Mercury. 



D«Win.— The success of the School of Engineering, established by the 

 University in 1842. has exceeded the expectations of its founders. Seventy 

 students at present are attending its classes. The course of instruction 

 lasts for three years. At the end of each year the students pass an ex- 

 aminalion previous to their being admitted into a higher class, and a final 

 examination for the University diploma ; the whole is under the control of 

 hir John MacneiU, L.L.D., Professor of Engineering in the University. 



Drainage of the Zuyrferjfs.— The works in operation for draining the Lake 

 of Haarlem, seemed to have stimulated the ingenuity of the projectors of a 

 stiU more gigantic undertaking— the drainage of the Zuvderzee, which ac 

 cording to a plan published at the Hague, is proposed to be effected by the 

 construction of an immense dike, cutting ofl the communication with the 

 North Sea, and by forming a canal between Amsterdam and the coast into 

 which are to be diverted the rivers which at present empty themselves intn 

 the Zuyderzee. 



Demolition of Trinify Church, Edinburgh.— Ihc North British Railway 

 Company have projected the destruction of this ancient building, erected in 

 1462 by Mary of Gueldres, wife of James II. of Scotland, and containing 

 her tomb. The conduct of the Commissioners of Woods and Forests in ap- 

 pealing to the magistrates for the preservation of this edifice, affords an ad. 

 mirable contrast to the cold, money-loving spirit which instigated its demoli- 



A Gallery of Art at Calcutta has been projected. The Government offer 

 to contribute 5000 rupees (£500). 



Button, the Archaologist — An entertainment in honour of this veteran 

 supporter of the cause of English architecture was recently given at the 

 Freemasons' Tavern. We regret to say that he himself was prevented by 

 indisposition from attending. ' 



Buckingham Palace.— The demolition of the colonnade in front of the 

 south wing has been commenced. 



Trinity Church, Paddingion.-The foundations of this church have par-

 site of the church had been raised 16 feet above the natural level e

THE GREAT BRITAIN STEAM SHIP. 



Mr. Brunei has addressed to the proprietors of this vessel a report 

 dated December 14th, of which the following is a brief analysis •_ ' 



The ship is at present comparatively little injured. The strains and 

 damage sustained are entirely local, and not communicated to the whole 

 hull, as would have been the case in a wooden vessel, under similar cir- 

 cumstances All the injuries done to the Great Britain might be repaired 

 if she could be got into dock. i">"eu 



To this object all attention ought to be turned, as the ship would scarce 

 paytheexpenseof breaking up; and if she were brought into port ex- 

 actly ,n her present condition, she would be worth from £40,000 to £60 000 

 It would require, at least, three months to complete the means of floating 

 her, and ,n the interim it is necessary that she should be protected against 

 the effects of the sea. To this end, Mr. Brunei proposes to erecl-not a 

 fixed breakwater, which has been already proved impracticable-but a 

 mass of fagots, used as in the protection of sea-banks in Holland The 

 strongest conviction of the cheapness and efficacy of this plan is expressed, 

 hough evy persons who have not seen the effect of a sea beating against 

 fagots will share in it." The fagots are to be packed closely agLft the 

 ship s exposed side for a considerable thickness and up to the level of the 

 deck. The whole is to be bound into a compact mass by rods, driven 

 through the fagols vertically, and is to be attached tightly to the shin 

 by iron chams. About 10,000 fagots would be required. 



So much for the means of protecting the vessel-next, as to the mode of 

 subsequently raising her. Mr. Brunei is of opinion that this cannot be 

 well effected by flotation. There are only 10 feet of water at ordinary 

 high tide, and she has worked herself 5 or 6 feet into the rock and sand 

 The weight to be raised is 2000 tons, and therefore if the buoyancy of 

 floal.ng camels were resorted to, the apparatus would have to be of enor 

 mous magnitude. 



It is recommended that, instead of hydrostatic, mechanical power should 

 be employed, and that when the ship is raised sufficiently to allow the 

 repairing of her bottom, she should be rendered water-tight, and then be 

 lowed to Liverpool or Bristol. 



MENAI TUBULAR BRIDGE. 



EXPERIMENTS AT BLACKWALI,. 



We have on one or two recent occasions witnessed experiments made oa 

 the huge model of the proposed tubular bridges of the Chester and Holyhead 

 Railway under the able direction of Alessrs. Hodgkiuson and Fairbairn, when 

 several other eminent engineers were present. The principal object of the 

 present experiments has been to ascertain the proper proportions of the sec- 

 tional areas of the top and bottom of the tube. Great additional strength 

 has been obtained by stiffening the side plates with vertical ribs of T iron 

 attached at equal intervals throughout the whole length of the tube 



In the first experiments, the sectional area of the bottom plate being 22i 

 •quare mche., of the top 24 square inches, and the sides 10 inches, a weight
