The Essay on the Geograpliy of Plants presents a 

 general view of the vegetation, zoology, geological con- 

 stitution, and other circumstances, of the equinoctial 

 region of the New Continent, from the level of the sea 

 to the higliest summits of the Andes. The second work 

 is by I\I. Bim])land, and contains methodical descriptions, 

 in Latin and French, of the species observed ; together 

 with remarks on their medicinal properties and their 

 uses in the arts. The Monography of the IMelastomse, 

 which is also from the pen of M. Bonpland, contains 

 upwards of 150 species of these plants, with others 

 collected by ^I. Ricb.ard in the West Indies and French 

 Guiana,* 



In his Essdi Geognostique sur le Gisement des Roches 

 dans les deux Hemispheres, published in 1826, and 

 translated into Englisli, Humboldt presents a table of 

 all the formations known to geologists, and institutes a 

 comparison between the rocks of the Old Continent and 

 those of the cordillcra of the Andes. 



The astronomical treatises liave been published in two 

 quarto volumes, under tiie iiileo'i Recueil d" Observations 

 Astronomiqufs ct de Mesurcs executces dans le Nouveau 

 Continent. This work contains the original observations 

 made between the 12tli degree of south latitude and the 

 41st degree of north latitude, transits of the sun and 

 stars over the meridian, occultations of satellites, eclipses, 

 &c. ; a treatise on astronomical refractions under the 

 torrid zone, considered as the effect of the decrement of 

 caloric in the strata of the atmcsphere; the barometric 

 measurement of the Andes of Mexico, Venezuela, Quito, 

 and New Grenada ; together with a table of nearly 700 

 geographical positions. The greatest pains have been 

 taken to verify the caleulatitms. Our author presented 

 to tiic Bureau des Longitudes his astronomical observa- 



* The works nmikeil 4, 5, and (! above, liave been preijarptl by 

 M. Kiinlli, one ol'lhe directors of tlie Botanical Garden ot Berlin.
