the larynx of the crocodiles, the quadrumani, and birds of the
tropics; the description of several new species of reptiles,
fishes, birds, monkeys, and other mammalia but little known. M.
Cuvier has enriched this work with a very comprehensive treatise on
the axolotl of the lake of Mexico, and on the genera of the Protei.
That naturalist has also recognized two new species of mastodons
and an elephant among the fossil bones of quadrupeds which we
brought from North and South America. For the description of the
insects collected by M. Bonpland we are indebted to M. Latreille,
whose labours have so much contributed to the progress of
entomology in our times. The second volume of this work contains
figures of the Mexican, Peruvian, and Aturian skulls, which we have
deposited in the Museum of Natural History at Paris, and respecting
which Blumenbach has published observations in the 'Decas quinta
Craniorum diversarum gentium.'

1.I.6. POLITICAL ESSAY ON THE KINGDOM OF NEW SPAIN, WITH A PHYSICAL
AND GEOGRAPHICAL ATLAS, FOUNDED ON ASTRONOMICAL OBSERVATIONS AND
TRIGONOMETRICAL AND BAROMETRICAL MEASUREMENTS.

This work, based on numerous official memoirs, presents, in six
divisions, considerations on the extent and natural appearance of
Mexico, on the population, on the manners of the inhabitants, their
ancient civilization, and the political division of their
territory. It embraces also the agriculture, the mineral riches,
the manufactures, the commerce, the finances, and the military
defence of that vast country. In treating these different subjects
I have endeavoured to consider them under a general point of view;
I have drawn a parallel not only between New Spain, the other
Spanish colonies, and the United States of North America, but also
