BA[N'S ELECTRO-CHEMICAL TELEGRAPH.
TEE most prominent chemical telegraph is that of Mr. Alexander Bain, of England. There are none others in practical
operation at the present time. In England, this telegraph is
worked by the old Electric Telegraph Company to a limited
extent. In the United States, through the wonderful energy
of Mr. Henry O'Reilly, the chemical telegraph invented by Mr.
Bain was used on an extensive range of lines about 1850. The
Morse companies instituted suits, and obtained injunctions
against the chemical telegraph lines, which produced a very
great change in the use of that apparatus in America. The Federal Court for the District of Pennsylvania held a very thorough
hearing on an application for an injunction, and a decree was
awarded, declaring the patent which had been granted to Mr.
Bain an infringement upon the original patent of 1840, granted
to Mr. Morse.
After this injunction, the other chemical telegraph lines consolidated with the Morse companies. At the present time,
there is but one electro-chemical telegraph line in America,
and that one extends from Boston to Montreal, with branches;
the whole making about 800 miles, and works in co-operation
with the Morse lines.

chemical telegraDh lines on both continents, I will, in the next
