for a church to be erected at Byculla by the 
inhabitants of Bombay.” 
The following are the surveys since 1813. 
TRIANGULATION. 
“ Since the year 1814 the Meridional Arc 
has been extended from Daumergidda to 
Seronj by Colonel Lambton and Captain 
Everest, being in distance north and south 
six degrees of latitude. 
A tract of country has also been triangu- 
lated in the Nizam’s dominions, of the ex- 
tent of about 30,000 square miles, by Colo- 
nel Lambton and Captain Everest. 
A chain of triangles has been carried from 
Seronj to within 50 miles of Calcutta, a dis- 
tance of about 12“^ of longitude, for the 
purpose of connecting that place with the 
Meridional Arc; the position of all the 
principal towns in the line of route has 
also been determined.

RECENT INVENTIONS MERITING 
THE ATTENTION OF THE PEOPLE 
OF INDIA. 
The first of these is the successful con- 
struction of a steam carriage. Hancock’s 
‘‘ automaton” is described in our present 
number and illustrated by a drawing. If such 
a one was constructed here, and suspension 
bridges were thrown over the different 
rivers, passengers might be conveyed with 
safety from Calcutta to Benares in 48 hours,, 
and from this capital to Bombay in about 
three days and a half. It is said that Dr. 
Church has built a locomotive carriage, to 
which we alluded in our last, which is also 
considered fully effective and satisfactory ; 
the specifications of which, embracing many 
important matters, will appear in a future 
number. We have only to add that the 
fact is now established, that steam may be 
safely and economically employed as an 
effective substitute for horses, steam coaches 
being now employed in the ordinary transit 
of stage coaches on the turnpike roads in 
England. The next point to which we 
would call the attention of our readers is 
the great improvements in aerostation : 
one article will be found in our present 
number on this subject, which states, on 
grounds extremely plausible, that this 
country affords peculiar facilities for the 
management of balloons. In our last num- 
ber it was shown that surveyors and archi- 
tects could now with great facility take cor- 
rect plans of noblemen^s estates by ascend- 
ing in a balloon.
