INTELLIGIBLE SIGNALS, Szc. 163 



The foregoing fquare forms the bafis of the following 

 table, at the foot of which will be found the method of 

 ufing it. This little elTay is only intended to illuftrate 

 it by fome examples. 



Suppofe I would tranfmit, by fignals, the following 

 phrafe, to my correfpondent. 



// 7ie devroit pas y avoir pour les Icttres d" autre pojlt 

 que r aerie nnc. 



1 . I look at the table, which is divided into two parts, 

 and fearch for the fyllables which in both parts are placed 

 in alphabetical order. 



2. I find il in the 5th column. I begin then by in- 

 dicating the fifth column, and place the figure s by itfelf 

 above the place for the units which are to follow. I then 

 place under it the figures, correfponding to the fyllable // 



inthe table 75, making i_ //. 

 75 



3. In the fame manner I find the fyllable ?ie in the 



3d column againft 16, -|- fi, and fo on till 1 get through 

 the whole phrafe. See A in the examples at the end of 

 this efTay. 



4. I keep a note of my letter, either to corre£t any 

 error that might efcape attention, or to make the table 

 the more familiar, and to enable me to write currently 

 in figures without looking at it. 



5. I only fend my numbers to the aerial poft as they 

 are placed in column B in the examples. 



6. The diredlor of the poft will only have to tranflate 

 thcfe numbers into longs ( — ), and briefs (<-•), as in the 

 column C, and to deliver this tranflation to the ope- 

 rator. 



7. The operator need only know how to exprefs, and 

 diftinguifh the longs and briefs by his inftriiment and 

 to wait the anfwer to one iignal, before he makes a 

 fecond. — ho much for the outfet.
