All these evils would be effectually removed, were a pro- 

 per apparatus of machinery contrived for performing this 

 operation. If care were taken to keep the j- 'Ip of one 

 thicknefs, ("and a gauge might easily be adapted to indi- 

 cate a change in this respect witli the utmost precision,) 

 every flieet must of necefsity be rf the same thicknefs 

 with others, and every part of tiie (heet alike, throughout 

 Its whole extent. It might liliev, ise be set to work a 

 thicker or thinner kind of pape-r, with a degree of precision 

 that cannot at present bs attempted. Yhese are conside- 

 rations that oag^.t to ir.duce papermal;ers to apply for the 

 aid of men of genius :n t!ie line of mechanics, much more 

 than they have othei~Ife done. Perfection in manufac- 

 tures can only be obtaii.ed by th.; combined efforts of mea 

 of science ir,the ll-:cs of mechanism and chemistry, with 

 industry and applic.tlon of the undertakers through every 

 department of their vroiks. 



Carriages upon sprir.gs. 

 Several persons about Edinburgh Lave lately contrived 

 carriages with sprir.gs for bringing to market articles that 

 are very tender and easily broken cr bruised. The straw- 

 berry dealers began tlis improvement, and the glafs- 

 house company at Lslth have followed their example. 

 In these cases nothing more is intended than merely to 

 diminifh the ihoc'is, to wliich the teii.';r articles put into 

 these carriages are exposed by the way. The owners of 

 these, and other mr.chiues of the same kind, arc net aware 

 that the dithculty of dvtght is thus greatly diiainiilied, 

 so tiiat one small horse will draw with ease in such a car- 

 riage, as much weight of goods as would have required a 

 much stronger horse to move it, if the weight had been 

 placed immediately upon the (hafts.
