New Wa~gon Steam Drag.. Mr. Boydell, of Dee Cottage, near Chester, has invented a locomo.

t i re engine, which, when fixed to heavy waggons~ ~c., will propel them on common roads at a very rapid rate. I t was exhibited on Tu'esday., and elicited the strongest approbation from many scientific and practi- cal men who witnessed the trial, and minutely examined the machinery. I t is applicable to ploughs, which it propels with great ease and velocity.

_Paris and Brussels Railway: The railway which has long been pro jec ted for unit ing the capitals

of France and Belgium,~at length bids fair to be commenced!in good earnesc~ The king of the French has iust granted to Mr. John Cock-

~' concesslon o[ erell, the celebrated English iron master of 'Leige, the • " '~ the railway for fifty years. The, French government is to advance ~5 per cent. of the cost, on the distance from Paris to the Belgian:Lfrontier; and Mr. Cockeril l is to be enti t led to all tolls and profits for the first half century, when, it is to be presumed, theworks wi l lhecome the o roper ty of the nat ion. The only condition with which the grant iz accompanied~ is. that the toll for the French 'por t ion of the rai lroad shall neve~c exceed ,fifteen francs, or 12s. 6d. The terms of concession were not agreed to until after the " high contractin~ parties~" Louis Phil ippe on one sid% and Mr. Cockeril l on the other, had had several personal interviews. The latter must be allowed t(~ possess a most adventurous.spir i t ; he was a severe sufferer by the revolution at Brussels in 1830; and yet~ i t seems~ is not deterred from ad.venturing his capital on a soil like that of France, which in .fifty .ydars may experience, probably, half as many revolutions.

The T/~ermo-electric Spark, obtained from a eingle pair of Metallic Elements. By Ma. FaAs'bls WATKI~S.

Vv:ith a pair of metall ic elements, Consisting of 'one bismuth and one antimony, weighing each five grains , and measuring 0.5 ofa'n inch long, and 0.12 diameter, when their ex t remi t ieswere unequally heated, I have obtained, with a Henry ' s fiat ribbon coil, a ~ e r y percept ible and bril- liant spark.

Now I have pen in hand, permi t me to state that with thermo-piles [ actuate most of the apparatus usually employed for i l lustrat ing electro- magnetic ~phmnomena, so tha~ the public teacher may now show by the same apparatus . the several rotations, ~ c . , w i t h thermo-electricity, as he does with voltaic electr ici ty.
