laiSCELIjANEA. 



I.akt r/Como.—la tht' Era ddla Barsa of Milan, there is an account of an 

 experimental trip, m.ade on the 1.5th N'ovcmlK-r Ia.st. of the iron steam boat 

 S'rrne. c. nslnictol for and under tIicsii|>erintin(Ienccof Mr. B. .-Mtano. C.K.. of 

 London, for the navipaiion of the Lake of Ciimo. She is 10.5 tons burden, 

 and was built in b;ni!and by Messrs. Ditchburn & Mair. and fitte 1 with a 

 pair of be.im engines of onlv 16 horses power each, by Messrs. Kennie. Tlie 

 following account is taken from the report of M. Caronti of Como (agent to 

 the "^leam Fkiat Company) to the directors at Mil.an. After a minute e.Nami- 

 nalionof the boat and engines by M. .Mbano, who m.a(le the reiiuired ar- 

 rangements for a trial, the boat lelt the Olm.> and arrived at the point of the 

 town of Torno, a distance of 5 miles, in 2J minutes, and in 5 minutes more 

 it renchcd the Pliniana with a strong head wind, and relumed direct from 

 the iMiint of Tonio to ilie port ot Como in 20 minutes. Al the first e.>;peri- 

 mental trip made on the 1 tih of October last, with the directors and a pnrty 

 en lionrd of above 100 persons, the boat performed then a journey from 

 fomo to Domaso. a distance of more than 30 miles, in 2 hrs. V> min.. aiicl 

 from Domnso to Como in 2 lirs. 35 min., the engines making from 3" to ,3n 

 strokes per minute, and the biKil remaining v.^ry steady in the water. Willi 

 sncl»sm:ill power this boat has done woniUrs. and it will prove a great de- 

 sicleralum to the travellers on the l^ike. who li.ive teen u.'id to travelling by 

 the old sleam barge, tunning at a speed of oiily 4 miles per hour. 



frrlavil.—A Presbyterian church has teen erected at Porlafirry, on tlic 

 site of llie former edifice, from the designs, and under the immediate super- 

 intend! nee of Mr. Millar, architect. The didicully of the sile (being a piece 

 of sloping grcund, at least 10 feet in 100) with which he had to contend, has. 

 in tliis instance, been changed into a positive and original beauty, such as 

 does not exist in any public building that we are acquainted w ith in the three 

 kingdoms. The first story, or body of the house, as it is usually termed, i-; 

 contained in a stylohate, eleven feet high, or massive pyramidical basement, 

 c(T which rises the columnar edifice. The lower portion of the building is en- 

 tere<l from the south end, through a vestibule on the same, or lower level, on 

 vihii'h this stylobate rests. (3n the north end. the stylobaie returns east and 

 west, formng an elevate 1 terrace level wiih the lack gallery entrance, and a 

 higher part of the street, thus giving space large enough lor a carriage to turn 

 with case, al the north jiropvlaum, which presents a front of si.t elegantly 

 proprrtioncd and massive Doric columns. The intercolumniaiions of the 

 lour centre ones, and returns to their aula-, are filled up to about one thirl 

 of their height with thin freestone slabs of larue superfici:d extent, reaching 

 from column lo column ; the rem.ining two-thirds being filled with giaz d 

 cast metal sashes of an exceedingly light descrip:ion; thus giving, by this 

 simple, though unique expedient, the great advantage of seeing the columns, 

 Internally as externally, which, by their undecorated finish, give the Hho!e 

 edifice the effect anil proporiion of simple, yet claiisic beamy. In a parallel 

 line to these, at nine feet farther b.ack, stand Ionic columns in anla-, sustain- 

 ing a vast beam, forming a marginal line to the ceiling of the house, « hich is 

 richly coffered ; the four angular coders being filled with ornamental venti- 

 lating centres of elaborate workmanship, and chaste design. At the south 

 end a similar screen extends from column to column, separating the vestry 

 from ihe lody of the church, agi'.iii.st which is placed the pulpit, in form of 

 the ancient rostrum, supjiorted on massive scroll tnis.«es. projecting from Ihe 

 wall, and fini.sbed in Sienna marble, so as to harmonize with tlie galleries 

 mud Its anKT in colour, it being part and parcel of the general design, 

 connecting them from right to left. 



Tlie style of architecture which Mr Mi lar has adopted for the very pecu- 

 liar site, i.i thai which prevnilol in (Jreece during the architectural age of 

 Pericles ; its dimensions are sullicienily birge to produce an impression of 

 grandeur and sublimity, which is not disturbed hy any division of parts; 

 and whether viewed closely, or from the opposite shores of .Str ingford, there 

 is nothing oblru.sive to divert the min I i f the sjieclator from couiemplaling 

 the miity. as well .as the majesly of miss and outlines — circumstances whitli 

 form liie first and most remarkable characterislics of the great prololyj'es 

 erected during the purer age of (irecian art, on which the architect has evi- 

 dently foundeil his studies ; thus stamping his works, where they have been 

 carried out under his own eye, with perlei lion and harmoni./us Ijcaulv, with- 

 out stooping I . Ihe factitious aiil mi adveniiiious emiHilishment. V/e would 

 fain hop," that such buildings as this, ended from the designs of a profes- 

 sional mm. may serve n» a stimulant in direcling public atienlion to tliis loo 

 much n.glened mI • • ' • Micularly in rousing ihe sell-eslecm of mem-

Dcvonpirt dockyard, assembled a! Woolwich dockyard to dec le upon the 

 plans which it would b,- most desirable to ailherr to'in future. .as a lixed prin- 

 ciple for building vessels for Her Majesty's mvv. This reso'u:ion on th» 

 part of the Admiralty will prevent all chances of difli'r.nce of o)iiiiinn on 

 such matiers. and prevent the pos^il,ility of the work ol ore niasler ship- 

 w right be;ng alter.d or condemned when the vessel is j-ent to any i.iher 

 dickyardthan the one where she was ccnslructed for repair, wliich has 

 sometimes been the case on former occasions. One fixed princi;>lc of ship- 

 building at all Her M-ijestv's dockyanls will be atlendcd with very beneficial 

 results to the service, and it would be advanla-iniis were the master ship- 

 wrights to meet annually, or nftener, to take into con-sideration such dis- 

 covenes as might be made owing lo the present advanced state of scientific 

 knowledge.

The Siram Engine.— ^-l. llelfcUiz.' has lately made a discovery among the 

 manuscripts i f Leonardo da Vinci, carrying back a kno«le.I_'e of the steam- 

 engine to at least the 15lh century. He Ins | ubii.'.hed. in lbc> .Irlislr. a notice 

 on the life of Leonardo da Vinci, to which he adds a fac simile of a paT 

 from one of his minuseri[ils. and on which are five sketches with the i«n, 

 representing the details of the apparatus of a slenm-gun, with an explanatory 

 note upon what he de.-ignatcs umier the name of the " Architoniicr.-p.'' and 

 of which note the lolluwinj is a translation : — " Invention of Arcbimeles. — 

 The Archi'.onnerre is a machine of fine copper, which throws balls with a 

 loud report and great force. It is used in the following manner ; — one-third 

 of this instrument contains a large quantiiy of charcoal fire. When tlie 

 water is well heated, a screw at the top of 'the ve.isel. which coniaius the 

 water, must be made quite tight. On closing the sfri'.v above, all ihe water 

 will escape below, will descend into the heated portion of the insirument,and 

 be immediately converted into a va|>oiir so abundant and powerful that it is 

 wonderful to see its fury and hear the noise it prinluces. This m.ichine will 

 carry a ball of a talent in weight.'" It is worthy of remark, that J.,eonarflo 

 <la \ irci, far from claiming the merit of this invention lor himself, or the 

 men of his time, attributes it lo Archimedes. — Galignani's Missiugrr. 



The Milan and Mmza Rnilwnii. — We have seen a report from Mr, Scott, the 

 locomotive engineer of the railway, lo Mr. Albaiio, C. V, , who Is snperin-

 Messrs. G. and !. Kennie, under the directions of Mr. Albano. She has 

 cylinders 13 in. diameter; 18in. stroke; 5ft. Gin. drving wheels ; weight 22

Palmeri Patent Elertrotint. — We have just seen some proofs printed from 

 plates prepared by a process for which Mr. Palmer, of Newgaie-sireel. has 

 laktn out a patent. The p oofs wliich we have seen are a do.;'s head, by 

 Mr. T. Sam;ison ; a study of a head by Wilkie, by Mr T. Samiaon ; a fisher- 

 man, skelcbe 1 by the same artist ; an I a fruit piece by Mr. G. Lance. This 

 method of prt'paiing copier plates and obtaining printed copies is callid
