which contrivance the tapestry may be suited to any room, whether the Hght 

 comes in on the right hand, or on the left. 



The patterns are painted on paper, on which are printed squares from copper 

 plates, and these subdivided by as many lines as answer to the threads of the 

 warp, which run lengthwise of the piece : then they try how many threads of 

 the shoot answer in breadth to every subdivision of the squares. Every thread 

 of the warp goes through a small brass ring, called a male, or through a loop 

 in the leish, and has a small long weight or lingoe hung below, to counter- 

 balance the packthreads, which going from the top of the rings or loops, are 

 passed over the pulleys in the table directly over the loom, and are continued 

 nearly in a horizontal position on one side of the loom, to a convenient dis- 

 tance ; where they are all spread on a cross-piece fastened to two staples: these 

 are called the tail of the mounture ; and from each of these packthreads, just 

 by the side of the loom, are fastened other packthreads called simples, which 

 descend to the ground ; so that by pulling tbese simple chords, you raise any 

 of the threads of the warp at pleasure ; therefore they fasten a loop or potlart to 

 as many of these simple chords as there are threads of the warp to be pulled up 

 at every shoot, or every throw of the shuttle; by which means the shoot shows 

 itself on the right side, where the warp is pulled up : and in ordering this, they 

 are guided by the pattern, on which they count the distances of the sub- 

 divisions, which contain the same colours in the same line, and can be shot at 

 once : then they fasten potlarts to the several simple chords, that draw up the 

 rings, through which those threads of the warp run, which are to lie behind 

 this colour ; they tie all these loops together, and fasten a piece of worsted 

 or silk to the knot, of the same colour that the workman is to throw ; and 

 the boy, when he pulls each loop, names the colour, that the weaver may take 

 the proper shuttle ; and so on for every colour to be thrown. 



An Account of the Condition of the Town of Hastings, after it had been visited 

 by the Small -pox. By Mr. T. Frewen. N" 410, p. 108. 



The following is a true account of the present condition of the town of 

 Hastings, after having been visited with the small-pox; which raged there 

 about a year and half. An account of those inoculated should have been here 

 inserted, if any thing remarkable had happened: they all had the distemper very 

 favourably, and continue perfectly well. 



The number of those that recovered of the small- pox, including 4 that were 

 inoculated, 608; died of it 97; escaped it '206; died of other illnesses since
