Miscellanies. 187 
The points are the markings of the Register, each point being 
marked every time the electric fluid passes. | 
The Register marks but one kind of mark, to wit, (V). This 
can be varied two ways. By intervals thus (V VV VVV) sig- 
nifying one, two, three, &c., and by reversing thus (4); examples 
of both these varieties are seen in the diagram. 
The single numbers are separated by short, and the whole num- 
bers by long intervals. 
To illustrate by the diagram, the word “ successful’’ is first found 
in the dictionary, and its telegraphic number 214 is set up in a spe- 
cies of type prepared for the purpose, and so of the other words. 
The types then operate upon the machinery and serve to regulate 
the times and intervals of the passages of electricity. Each pas- 
sage of the fluid causes a pencil at the extremity of the wire to 
mark the points as in the diagram. 
To read the marks; count the points at the bottom of each line. 
It will be perceived that two points come first, separated by a short 
interval from the next point. Set 2 beneath it. Then comes one 
point likewise separated by a short interval. Set 1 beneath it. 
Then come four points. Set 4 beneath it. But the interval in this 
case is a long interval, consequently the three numbers comprise the 
whole number 214. 
So proceed with the rest until the numbers are all set down. 
Then by referring to the Telegraphic Dictionary, the words corres- 
ponding to the numbers are found, and the communication read. 
Thus it will be seen that by means of the changes upon ¢en charac- 
ters, all words can be transmitted. But there are two points re- 
versed in the lower line. ‘These are the eleventh character, placed 
before a number to signify that it is to be read as a number, and not 
as the representative of a word. 
Since the 4th of September, one thousand feet more of wire No. 
23 have been added, making in all two thousand seven hundred feet— 
more than half a mile of a reduced size of wire; the ucla still 
recorded accurately. 
Arrangements have been made for establishing a circuit of several 
miles, and for constructing new and accurate machinery. Profs 
Gale, of the New York City University is engaged with Prof. Morse . 
in making some interesting experiments connected with this inven- 
tion, and to test the effect of length of wire on the magnetizing in- 
fluence of voltaic electricity.
