This volume terminates the second volume (in Quarto) of 

 the Personal Narrative. Each volume of this work appears 

 in two parts ; to the last will be annexed a very copious Table 

 of Contents, in which the physical and geological observa- 

 tions will be methodically arranged. It may not be amiss, 

 to take this opportunity of stating, that eighteen volumes of 

 the large edit ion of the Voyage to the Equinoxial Regions of the 

 New Continent have now appeared, eleven of which are in 

 quarto. There remain to be published, 2 Vols, (in quarto) of 

 the Persona! Narrative, 1 Vol. of Zoology, 2 Vols, of the 

 Nova Genera et Species Plant, cequin., the Magnetical Observa- 

 tions, and the new edition of the Geography of Plants. 



The sketches of maps cited in the discussion on lake Pa- 

 ri ma, (p. 839 to 859 of the present volume), will appear in the 

 next number of the Geographical Atlas. The map of the 

 Rio Grande de la Magdalena, containing a considerable part 

 of New Grenada, is the result of the astronomical observa-^ 

 tions and barometric measurements, which I made during a 

 navigation of sixty-five days. T drew this map on a very 

 large scale, in the month of August, 1801, during my resi- 

 dence at Sauta-Fe de Bogota. It is the first map of the 

 River Magdalena constructed astronomically. Copies of it 

 Mere left in the hands of the viceroy, and of the celebrated 

 botanist, Mr. Mutis j other copies were sent to Carthagena 

 and to Spain. Having given this map to be engraved in 

 1816, I could not avail myself of the topographic particulars 

 of the islands and the sinuosities of the river, which are found 

 in the Spanish map published at London, in the mouth of 

 September, 1820, by lieutenant colonel Don Vicente Talledo, 

 entitled, Mapa corografco de la Provincia de Cartagena dc 

 lndias. This curious map comprehends the half of the Rio 

 Magdalena, from it's mouth as far as the Strait of Carare. 

 The court of Madrid, informed of my geographical labors, 

 by the viceroy, don Pedro de Mendinueta, was desirous of 

 having the degree of their precision ascertained on the spot.
