study Turkish, and then, leaving the diplomatic service, undertook during 1847-1863 a series of expeditions in Asia Minor, during which he made extensive scientific researches and collections. The results were published by Chikhachyov in an enormous work, Asie Mineure: Description physique, statistique et archéologique de cette contrée. This work, embracing the geography, geology, climatology, zoology, botany, and paleontology of Asia Minor, represents the classic work of Chikhachyov in cooperation with numerous experts on different branches of the natural sciences. After completing his Asia Minor researches, Chikhachyov ended his great travels and expeditions, having reached old age, but did not stop scientific work. In early 1878, at the age of 71, he visited Algeria and Tunis, and in 1880 he published a description of his travel under the title Espagne, Algérie et Tunisie. Besides his geographical and natural-historical works, Chikhachyov published a number of political works on the Eastern Question. Death In 1890, he published a few natural-scientific articles under the title Etudes de géographie et d'histoire naturelle. These represent fragments from what Chikhachyov conceived as a large scientific work on the world's deserts which he did not have time to finish, dying in 1890 of pneumonia. In encouragement of travelers across Asia, Chikhachyov left to the French Academy of Sciences the sum of 100,000 francs.
