leges were made to correspond with his rank." Fortunately 

 Baudin died during the voyage, otherwise it seems extremely 

 doubtful whether the expedition would ever have returned to 

 France. After three years of perilous adventure and almost 

 indescribable hardship, the expedition returned, in March, 1804. 

 Although Lesueur nearly lost his life from disease and the bite 

 of a venomous reptile during the voyage, he found opportunity 

 to execute no less than fifteen hundred drawings and paintings 

 of the zoological collection which was said to have numbered 

 more than one hundred thousand specimens. Some, but not 

 nearly all, of these drawings appeared in the history of the 

 voyage published in 1807. In the fall of 1815 Lesueur was 

 invited by a wealthy Scotch-American, Mr. William Maclure, 

 to accompany him as traveling companion on a voyage to the 

 West Indies and thence to the United States. Maclure was a 

 pioneer geological explorer who did much to advance the natural 

 sciences in their early days in this country. Lesueur accepted 

 and the party arrived at Barbadoes in December of that year. 

 The winter was spent in collecting marine animals which after- 

 wards formed the basis of Lesueur's admirably illustrated papers. 

 In the spring of 1816 he arrived in the LInited States, and after 

 considerable travel, settled in Philadelphia where he soon 

 became a member of the American Philosophical Society and the 

 Academy of Natural Sciences. Here he remained, according 

 to Ord, for nine years, engaged in scientific pursuits and the 

 teaching of drawing in the educational institutions of that city- 

 It was during this time that Lesueur doubtless met Thomas 

 Say, although it is not known exactly how they became associ- 

 ated. As Lesueur afterwards accompanied Say to New Har- 

 mony, they must have been on very friendly terms. Probably 

 they met through the agency of the scientific societies to which 

 they both belonged, Say having been elected to membership in 

 the Academy in 1812. Dr. Morris says "It was during this 

 period that Thomas Say came under Lesueur's influence and it 

 is said that it was to him that Say owed his first acquaintance 

 with marine invertebrates and other departments of zoology." 

 In 1825 Lesueur accompanied his friend Say to Indiana and 

 took up his residence in the socialistic colony founded by 

 Maclure and Owen at New Harmony. Of this event Dr. 

 George Brown Goode says: "But for their sacrifice to the 

 socialistic ideas of Owen, Say and Lesueur would doubtless be 

 counted among the most distinguished of our naturalists, and 

 the course of American zoological research would have been 

 entirely different." Although American entomologists doubt- 

 less will agree with Dr. Goode regarding the unfortunate results 

 of this venture, most of us will be slow to accept the idea that 

 Thomas Say is not already enrolled among the "most dis- 

 tinguished" of earlv American naturalists.
