VERY SIMPLE tELEGRAPH. 1^7 



"^y holding the right arm in fuch a pofition that the hand Telegraphic 

 fliall be above the head, or touch it, the point of interrogation ^^^^^^^"^ ^^' 

 is made, (?). 



The fame motion performed with the left arm, furniflies a 

 lign for the point of admiration, {!). 



The three figns of the termination of a word, of a comma^ 

 and of the point of interrogation, each combined with the 

 three different angles made with the other arm, form the nine 

 figures. 



By putting the right arm at reft on the hip, and forming the 

 three angles of 45°, 90®, and 135°, with the extended left arm, 

 the iigns are given for the figures 1, 2, and 3. 



By refting the left arm on the hip, and making the fame 

 three angles with the right arm, the figures 4, 5, and 6, are 

 formed. 



By bringing the right arm to the fign of the point of inter- 

 rogation, and repeating the three angles with the left ^rm, the 

 figures 7, 8, and 9, are formed. 



To indicate zero, (0), the two arms are raifed fo that the 

 hands (liall be above the head, or touch it, 



To exprcfs 10, the figns of 1 and are made without making 

 either the fign of the termination of a word, or of a number, or 

 that of a comma, between thefe two figns. To exprefs 1 1, the 

 fign of 1 is twice made, with the affiftance of the fign for the 

 termination of a character, or of a figure. To indicate 12, the 

 figns of 1 and 2 are made, and fo on : 10, 11, and 12 may be 

 exprefled at pleafure, each by a fingle fign, by placing the 

 left arm in the pofition of the point of admiration, and by fuc- 

 ceffivcly forming with the right arm the three angles pf 45°, 

 90<>, and 135'=^.. It would not be difficult to devife a great 

 number of figns to exprefs 1 3, 1 4, 1 5, and many other number?, 

 each by a fingle fign. 



If it be intended to make ufe of this natural telegraph at the Mechanical ad- 

 diftance of <me, or even of feveral leagues, or to dp without aJ?J°^^^"[fi'"* 

 telefcope at lefs confiderable diftances, it is only neceflary to 

 add to each natural arm an artificial ojie, that is to fay, an 

 oblong frame, of the breadth of a foot or thereabout, and of 

 the length of one or more yards. This frame muft be coveredl 

 with oiled filk, or any other fluff of a dark colour, and muft be 

 provided with a handle to hold and dired it. Our telegraph 

 iv-ould here no longer be called natural, but it is ftill among
