172 REPORT OF THE COMMISSIONER OF FISHERIES. 
arrived, May 10, 1816, at New York, and there became acquainted with 
the statesman-ichthyologist Samuel Latham Mitchill. In the fall of the 
same year he visited the coast, and especially fishing towns, of New 
England, and the fish market at Boston. His collections afforded him 
a number of new species, which he subsequently described in various 
articles in the Journal of the Academy of Natural Sciences of Phila- 
del phia.@ 
In 1817 he settled down in Philadelphia and at once became an inti- 
mate associate of the scientific men of that city, and his was the first 
article contributed to the first volume of the Journal of the Academy 
of Natural Sciences—-that journal which has since extended into so 
many. It is in that series that were published a number of articles 
illustrated by his unrivaled pencil. ‘Thirteen specific names were 
framed for fishes obtained in Massachusetts, but most of them have 
not stood the test of time and comparison with more material. Lesueur 
remained at home in Philadelphia, more or less, till 1825. He then 
accompanied his old patron, Maclure, to New iontaetye Ind., where 
they hoped to live an ideal life in a socialistic colony. It is almost 
needless to say that they were disappointed. While in New Har- 
mony, Lesueur issued a prospectus fora work to be published in parts, 
by subscription’, on the ‘Fish of North America, with plates drawn 
and coloured from nature.” The demand for the work was not sufli- 
cient to justify its publication, and the project fell still-born. After 
various adventures and much sickness, he left, by way of New Orleans, 
for France, and after an absence of twenty-two years was again at 
Havre in 1837. In Paris and in Havre he passed most of the remain- 
der of his life and for the last two years was director of the museum 
of the latter city. He died on the 12th of December, 1846.

b Thirty-five plates had been engraved by Lesueur for his projected work, and a sample number 
with 6 leaves of text (unpaged) and 5 plates (illustrating 3 species of ‘' Petromyzon”’, 1 of ‘“Ammocates”’, 
and 1 of ‘‘Aceipenser”’) was issued from New Harmony, Ind., in 1827. A notice was published by Leon 
Vaillant (Note sur l’ceuvre ichthyologique de C, A. Lesueur) in the Bulletin de la Société Philoma- 
thique de Paris in 1896 (8. ser., t. VIII, 15-83), descriptive of the plates, and a smal! edition of 40 copies 
with proofs from the 35 plates was issued by the editor soon after.
