region in every direction, and accumulated in their herbariums the plants of 

 the East. The expedition of Col. Chesney on the Euphrates and Tigris, 

 opening new routes to English enterprise, has also not been without its 

 advantage to botany. 



" For the Caucasian district alone, the Germans and the Russians, following 

 in the train of military expeditions, have, for the last twenty years, rendered 

 incalculable services to botany. I will only name, at present, Bieberstein, 

 Szovits, C. A. Meyer, and Hohenacker. A notice of their labours, as well as 

 of those which belong to the last age, may be seen in the essay of M. Trautvet- 

 ter, entitled Grundriss einer Geschichte der Botanik in Bezug auf Russland 

 ( Sketch of a History of Botany with regard to Russia), extracted from the 

 Memoirs of the Academy of St. Petersburg. 



" In establishing, as it were, the foundation of a flora of Western Asia, it 

 was indispensable to add to our Illustrationes a geographical chart of this 

 region, tracing out the principal itineraries of botanical travellers. I have 

 noted them down myself, with the greatest care, from all the documents which 

 I have been able to procure : that of Michaux is extracted from the inedited 

 collection of manuscripts of botanists which forms part of the gallery of 

 M. B. Delessert. These travels have supplied me with valuable information, 

 not only as to the localities mentioned in the herbals, and the habitat of 

 plants, but also on the deficiencies in geography itself. The grand works of 

 M. Texier on Asia Minor, Armenia, and Persia, and the beautiful general map 

 of Persia on which Col. Lapie has been engaged for a length of time, will 

 throw great light on these countries; but they have both agreed, till their 

 important labours are published, to lend their aid in the construction of a, 

 particular map to answer our purpose. All the itineraries of M. Texier are 

 also marked ; so that it will serve as an index map to his Atlas. We have 

 thought it advisable to add the itineraries of Corancez, and of my colleague, 

 M. Leon de la Borde, both Frenchmen, but not botanists, no less on account 

 of the individual merit of the works, than of their connexion with the travels 

 of M. Texier. 



" We have been careful to mark on the chart all the authentic indications 

 which we have been able to procure of the heights of places above the level 

 of the sea. Many of these indications are from the barometrical observations 

 of M. Texier, revised by Col. Delcros, who has been of the utmost assistance 

 i» us in this part of our labour. We are confident that our chart will be of 

 great assistance to botanists, whether in facilitating the classification of the 

 localities in herbals, or in calling their attention to points still unexplored ; 

 we even hope that it will be adopted by all travellers, whatever may be the 

 object of their researches.
