[Mat, 



prulongiug the ebullition, the violet lint becomes deeper and deeper if the 

 qimntily of organic matter be considerable. Hut the mere brown lint 

 alone serves lo show Ihat the quantily of organic mailer exceeds Ihe ordi- 

 nary proportion. 



I'la.T Adulteration. — At the .\cademy of Sciences, Paris, M. Boussing- 

 Bult read a report of a eommillee on a paper by M. \'incen(, relative to 

 the means employed in delectin!; by a chemical test liie admixime of 

 jihiirmium temix,or New Zealand flax, with the hemp and flax of Kuro- 

 pean growlii and preparation. The phorm'uiin ttnav does not possess cer- 

 tain qualities essential for naval cordage, and it was considered imporlaut 

 to discover Ihe means of delecting its presence. ^I. Vincent has found 

 that if llie pltormiiim tenu.r be immersed in pure nitric acid, ils fibres, owing 

 to the presence of some azotic substance, take a blood-red liiil ; which is 

 not the case with Ilie hemp and flax admitted for use in tiie navy. Thus 

 it is very easy, by subjecting a rope to ihe action of nitric acid, lo discover 

 whether there has been any admixture of pliurmiuin tenax. The report of 

 the comniitlee confirms the statement of I\I. Vincent, 



Miiiiure^. — At the .\cademy of .Sciences, Pai'is, a paper was received 

 from >I. J. Perso7. relative to the influence of certain manures on vegeta- 

 tion. He states Ihat a mixture composed of potass, dried blood, and goose 

 dung was found to have great efffct upon vines. He also mentions a ma- 

 nure for horlensias, composed of potass and burnt bones treated with 

 uilric acid. 



Rnilicny Abitttoiv. — At ibeTrowse station, Norfolk, an abattoir, consisting 

 of two sets of slaughter-houses, has beeu built and fitted up with every 

 convenience for slaughtering 100 beasts and SOI) sheep daily. The build- 

 ings and yard are enclosed within high brick walls, and the yard has 

 been divided into compartments or pens for Ihe beasts and sheep. Adjoin- 

 ing Ihe slaughter-house, there is a large lank to supply water. Close lo 

 Ihe open end of Ihe houses there is a siding to and from Ihe railway, on 

 which Ihe trucks run lo be loaded with carcases. 



Iron Bridge fiui/s. — Mr. M'ood, of the Uritish Iron Company's Morks, 

 Abersychan, has succeeded in rolling bridge-rails weighing UU lb. per 

 yard, 30 feet long. 



The Adiiiiraltii Electric Telegrnjih. — The lords of Ihe Admiralty have 

 at length directed the extension of ihe South Western Railway sulilerra- 

 nean ehxlric telegraph to Ihe Admiralty at Whilehall, It will branch off 

 in Ihe Strand near Ihe company's present ollices. 



The '• Prince Metterniclt" Steam ]'essel. — This splendid steamer, of 

 600 Ions, and aoohorse power, fitted with Morgan's patent wheels, made 

 her trial trip on Thursday, April 1st, for the purpose of ascertaining her 

 draught of water and average speed, at llie standard mile in Lung Iteach. 

 This vessel and her machinery are the joint production of IVTessrs. Dilcli- 

 burn and Mare, of lilackwall, and Alessrs. Penn, of Greenwich ; she was 

 built for the Danube .Steam Navigation Company, and constructed ex- 

 pressly to navigate between Galalz and Constantinople, and it is intended 

 she should combine the properties of a sea-going and river steamer, as far 

 as these qualities can be united. 'I'he contractors were bound by special 

 agreement to produce a vessel Ihat shonhl realise an average speed of Ij 

 miles per hour, and not lo draw more than six feet water with 120 tons of 

 dead weight on board — which she morelhan realised. At Ihe trial trip she 

 passed up and down the mile six times, with and against the tide, at an 

 average speed of l.'ij miles per hour. 



Important Suiing in Draining. — A correspondent of the yottiiigltam 

 Mercury states thai an enormous saving is lo be eU'ecled by Ihe use of 

 pipe-tiles made by machinery, instead of horse-shoe tiles made by hand. 

 *' There are at this lime," he says, ou liie authority of the chairman of Kx- 

 cise, " in the county of Nollinghani, 97 brick and tile-yards, making in 

 the year, by hand, not less than 8,000,000 drainage tiles." The cost of 

 B,000,000 horse shoe aud 4,000,000 flat tiles is about £10,900, while 

 8,000,000 pipe-tiles — with which flat ones are uot required— may be made 

 for £6,034, or at a saving of £10,800. The writer adds that last summer 

 he made .'>00,000 pipe-tiles at from 10s. lo 12s. per thousand, by a machine 

 which cost him no more than f 3."i. The superiority of pipe-tiles is very 

 great. " They are stronger and less liable lo break, both in carriage and 

 in use. They require no flats ; they lie more evenly and securely in their 

 bed. No vermin can gel into them. They form a belter channel for the 

 water, and scour themselves clear of silt. They are much lighter and 

 more portable." 



Durham Cathedral. — The inappropriate wooden screen which separated 

 the nave from Ihe choir, and nluch was placed there by Prior W'essinglon, 

 between the jears 1410 aud 144), logellier with the great organ imme- 

 diately above it, has been removed. The organ is lo be placed ou Ihe 

 north side of the choir, immediately opposite lo the bishop's throne, where 

 it will remain permanently if Ihe situation on trial iiroves suitable. Tiie 

 end stalls will iheu be thrown back, ^o as to make more room in the choir 

 — a change long wauled — and a temporary iron railing will be run across 

 to separate llie choir from the nave, which railing will be replaced by a 

 permanent screen, when il shall have been determined what descripiioii 

 wonlil be most appropriate. A low sloue (lolhic screen is conleniplaled. 

 The visitor, on entering the cathedral, will now be struck wi li tin- iiinn- 

 terrupled aud magnificent view which he obtains of the interior from wei-t 

 to east.
