I. BAROMETERS.

a. List of the barometers. During our different journeys we used in all sixteen
barometers. When starting from Europe, 1854, we had with us one syphon and two
cistern barometers from Berlin, and three cistern barometers from London.

In March, 1855, we received at Calcutta, through the kindness of Major Thuillier,
three mountain barometers by Newman, which were used by our assistants for corre-
sponding observations.

In the following year, five cistern barometers by Pistor of Berlin, which had
been most carefully executed under the superintendence of our friend, the late Baron
Humboldt, reached us in Calcutta, and lastly, before starting for his last fatal journey,
Adolphe received two more small mountain barometers by Troughton, probably from
his friends at Peshaur.

The following are the ISTos. we use for the barometers in our observations, to-
gether with the makers' Nos. and signatures.

We mark with an asterisk those which may be considered as standard baro-
meters, from their having a large diameter of tube and cistern, and from keeping
their correction unaltered.
