New Patents lately/ Enrolled. 



[Oct. I, 



paper b_v Mr. Gilpin was re.ad, contain- 

 ing iiitcrefting and curious Obfervations 

 on tiie Dip aiid Variation of tiie Magne- 

 tic Needle, made at his apartments in 

 Somerlet-Houi'e, under the direction of 

 Air. Cavcndilli, for the hill leu years. 



A paper was alio re;i',l, bcma an Ac- 

 count of an Analyfis of a kind of native 

 Iron found at tlie Cape of Good Hope, 

 by Air. S.MiTusoN Te.vnan r. The me- 

 tal confilled of an alloy of nickel and 

 iron, in the proportion of one of the for- 



mer to ten of the latter. It yielded 

 plumbago when treated with acid. 



At tlie fame fitting Dr. HEESCHEt 

 furniflied a paper as a Summary of and 

 •Sequel to his former I'ajicrs on the Fi- 

 gure of the Planet Saturn, lie now is of 

 opinion that the diameter of that planet 

 is much greater at the equator than he 

 formerly I'uppofcd, but that it is much 

 flatted at tlie poles. The Society then 

 adjourned to the iii-lt Thurfday in TIo- 

 vciiiber. 



NEW PATENTS LATELY ENROLLED. 



J»R. THOMAS FRICKER and MR. RICHARD 



Clarke's, (bond-street,) for a new 

 !Mode of Decorui'iiif^ the WaHs of 

 Apurtmaits in Indlutiim of fine Cloth, 

 without Joint, Scum, Sc, bi/ Mean^ of 

 cementing Flock on Walls of Plnfter, 

 S,c. 



TIJE wall to be decorated muft be 

 firll made very finooth and even by 

 means of piniiicc-ftone ; it is then to be 

 done over with itrong lizc ; and when 

 dry the operation is to be repeated. Af- 

 terv ards a compotirion is to be made, 

 coiififtmg of one gallon of linfced-oil, one 

 gallon of turpentine, and one pound of 

 gum aiilina, boiled, with colouring mat- 

 ter fuch as the; colouring of the flock to 

 he nfed, till it comes to the thicknefs of 

 tar. Tlic wall, as foon as ilic fccond bo- 

 dy of fize is dry, is to be done over with 

 this compolitiou, and left veiy fmooth ; 

 the flock is to be made of the refufe of 

 woollen-cloth, filk, or cotton, and is to 

 be put into a box having the properties 

 of a pair of bellows, with a iiole in the 

 middle, and through this hole it is to be 

 forced againft the wall wliile it is yet wet 

 with the aforefaid compofition. A ma- 

 chine like ahair-drc'lVer'spowderii!g-bo\, 

 with the b.ole perieoily open, is likewife 

 recommended for the puriiofc of cover- 

 ing the wall with flock. 



MR. RICHARD -WILLCOX'S, (lAMBETH,) 



for Machinery for the mora-expeditionh 

 ly Cuttinii and Slrippin:: (he various 

 Furs from Skins noa cut or ftripped by 

 Hand, and for fiindri/ Mtt hods of Pre- 

 paring and Clcanftng the fid Skins. 

 Inftead of the left hand", now ufually 

 employed, Mr. Willcox fubftiiutes a thin 

 pjate "of metal, ivory, kc, capable of 

 holding down the fur, which is placed on 

 iu edge, and preffed iji coutsa wilk tha 



felt of the lliin, previonfly laid fmooth, 

 either on a horizontal bed or on a roller. 

 The apparatus ncceflary for advancing 

 the rtiin, as the fur is cut, is exhibited in 

 the drawing attached to the fpecirica- 

 tion. One part of it requires the appli- 

 cation of the hand and foot of the work- 

 men ; but the other requires no other 

 action than that of tlie firft mover, which 

 may be a fteam-engine, or any other 

 fource of jiower, together \vith the atten- 

 tion of tiic workman to fupply the pelts, 

 as may be necelVary. 



To i)roducc a iiniilar effect, the metal 

 or ivory roller is ufed, which it to be mo- 

 derately prclVed ill contact with the fur- 

 face of the pelt, the faid roller being 

 turned in a contrary direction to that of 

 the Ikiii, by which the fur is eflectually 

 drawn or removed out of the way of the 

 knife, and prevented from being mutila- 

 ted or cut lliort. 



Agiiin, for elTeCtually fcparating the 

 fur, and for cutting, or cutting and pluck- 

 ing, in the fiune machine, witli tlie roller 

 is employed apiece of canvas, or other 

 flroni; material, joined at the two extre- 

 mities, and forming a perpetual web 

 round the fuid rollers. By this means 

 the cnnvas bcinj^ preflcd in contact with 

 the furface of the ikin, and moving with 

 about double the fpeed of the flcin, in a 

 contrary direction, cauf(;3 the fur to ad- 

 here to the faid car.vas in the exact "order 

 and lituation as it was on ti;e Ikin or pelt, 

 where it mav be divided or locked, at 

 the option of the perfon attending th* 

 machine. The long or coarfe hair with 

 the fur is alfo cut without previoully 

 plucking, becaufe both adhere to^ the 

 canvas, which, being paflVd out of the 

 ■ way of the catting part of the apparatus, 

 the fame is caufecl to pafs over one of the. 

 leading rol'crs vihcte the canvas is bent 

 ncdily
