A NATIONAL PAPER, PUBLISHED WEDNESDAYS AND SATURDAYS BY JOHN FEN NO, No. 69, HIGH-STREET, PHILADELPHIA Wednesday, August 8, 1792. [Whole No. 452.] 77 Or\ tin ufti that max be made of Coutchouc* Guvty or Indian Rubber, in Arts and Manufactures,' an account of the manner of obtaining and md nujacluring it. (concluded.) 6th. A F.ROSTATION is now nearly at a stand ; xa. but it is wonderful rjo one ever per ceived the use that might have been made of this substance for that purpose. No kind of silk, or other light substance could ever be found, that pot fetfed the fmaileft degree of elasticity ; by confe r quence, when they afcendcd into thp higher Re gions, the expanfioa of the gas was in danger of buifting the globe ; it was therefore neceffarv t leave it open below to guard against that accident. A globe of coutchouc would have polfeffcd the quality here wanted ; it would have expanded as the circumstances of ih? cafe required ; and while it was perfe&ly to prevent the involuntary escape of the fmaileft quantity, it would have adapt ed itfelf in size to every variation of circumstances. It is true, the retentive power of this substance, when very thin, has nevei y>et been afcertaiijed by experience ; but there is reason to believe it ii ve» rv great. ' 7th. As this substance is inflamable, and burns with a bright/lame withoyt requiring ?ny wick, it might be employed perhaps with great economy as torches or flambeaux. Solid balls have also been made of it, that are light, and of an amazing de gree of elasticity ; but what ufeful purpose could be made of these, does not at present appear It might also be moulded into the foipi of riding whips, and would probably answer that purpose admirably well ; and after they wefe wore oy.t, they might be employed a« torches. ,Bth. As a material for chiryrgicpl purpofos, it might be employed on occasions. Catheters ( have already been made of it, after having been dissolved in aether, that have been found to answer the purpose wanted, and to occasion irlueh less ir ritation in the parts than those of wiy other fort that have yet been tried ; but the great price, \yben thjus manufafturcd, prevents them from cowling into general use. The little bottles, when applied to the breads of women distressed with fore nip-r pies, can be so managed,.as to occa&on a more gentle fufliou than fatf be any other \v?y, and have therefore afforded v.eiy great relief. In ftiort, the variety of uses to which they might be applied, as bags for in jewing or 4or fucking", are too numerous, to adm.ut of being there so much as pointed at. 9th. Elajlic springs. In all cases where a fp,ring is wanted to att by us contrflflijc power, no sub stance can be conceived niore proper, than that of which we now speak, especially in coid climates ; and there are innumerable cases in which it might be employed in this tnanner with the happjelt effect, in various kinds of machinery. 10th. It is many years since Dr. Bcrgius at Stockholm, made some experiment# on this sub stance in Pa pita's digester : By fubje&ing ij in that way to an intense degree of heat, it is said to have beeaconvcitcd into a hard, eUftic, horn-ljke fub ftrnce. I have not heard that these experiments have been repeated ; but if upon farther trial, this' fhajl be found to be invariably thercCult, it would! extend the utility of this substance, far beyond the limits we have hitherto thought of; but in the state of uncertainty that at present prevails on that head, it would be improper so fay more. I might go on at this rate for many pages toge ther, pointi/ig out varjpus other uses to which it might be applied ; but J (hall content myfelf with fpecifying one other only. Geographical globes are at present an article of ex pence, jMpecjalJy when of such a as to admit of exhibiting a tolerable view of the earth'* furfact. These could be ijiade of coutchouc of a-ny size required, at a very moderate ex pence. The favagesot America whom cuir philosophers repre sent as destitute of every fTventaJ endow ment, will teach us the way of proceeding. Thd little bottles we import fropi thencc„ arc formed upon m®ulds of clay dried in the fun. When the coutchouc has hardened on the furfacc bv the process already at produces this singular substance. In no one instance that I knpw has the inatten tion of mankind to ufeful improvements been more conspicuous, than with reipedt to the object of our present dilcuflion. It is not inudh lels than sixty yeais since Mr. us chara&ers,, whom the Citizens of every denomination, and in evciypart of the ftate,deem to be qualified for Representatives in Concrete, and Ele&ors of a President and Vicc.-PreGxlent of the United States : and to submit this lift,, with out the influence of a fele&ion, or a comment, to the deliberate consideration, and unbiaiTcd fuffrag es of the People.
