64 . A NOTICE OF THE 



publishing committee aided them in the work, as well as they 

 knew how, and it is traditionary that Mr. Say attempted on 

 eeveral occasions to set types, but with very moderate success. 

 Mr. Ord, anxious to forward the publication, translated or rather 

 prepared the papers of M. Lesueur from materials furnished by 

 him, as that gentleman, who immigrated from France in 1816, 

 possessed very little knowledge of the English language. By 

 such irregular means nearly all of the second half of the first 

 volume was produced. In spite of such zeal and unusual labor, 

 the Journal paused for want of money, before the close of 1818 ; 

 and it was not again resumed until 1821, when Dr. Isaac Hays 

 undertook its management, and through his efforts the publication 

 continued till the close of 1825, without incurring any new debt. 

 The printing was done in the office of Mr. Jesper Harding. 



The establishment of this journal, and its maintenance, are 

 due chiefly to the efforts of the Publication Committees, some 

 members of which, as already stated, assisted at the press ; but to 

 Dr. Isaac Hays especially, we owe acknowledgments for his in- 

 dustry, zealous perseverance, and success, in reviving and sustain- 

 ing the journal through many trials and pecuniary difficulties.* 



The Journal of the Academy of Natural Sciences, thus began, 

 continued to be published at irregular intervals, a number being 

 issued whenever sufficient material was furnished to make it up, 

 until 1842, a period of twenty-five years.
