ALSO INSCRIBED, 



AS A TRIBUTE OF AFFECTION^, 

 TO THE MEMORY OF MY EARLY AND ESTIMABLE FRIEND; 



I-ATE SURGEON IN THE NAVY OF THE UNITED STATES : 



A MAN IN WHOJI THE LOVE OF SCIENCE 



WAS EQUALLED ONLY BY HIS BENEVOLENCE TOWARDS HIS FELLOW CREATURES. 



WHO, TO A MOST AMIABLE SIMPLICITY OF CHARACTER, 



UNITED A RARE SAGACITY, AND AN INDEFATIGABLE ACTIVITY. 



IN THE PROSECUTION OF BOTANICAL KNOWLEDGE. 



HIS ARDOR IN THE PURSUIT, 



VZD HIM TO UNDERTAKE AN EXPEDITION TO WHICH HIS DECLINING HEALTH 

 WAS TOTALLY INADEQUATE : 



AND, ON THE BANKS OF THE MISSOURI, 



FAR FROM THE BOSOM OF HIS FAMILY, 



AND THE CIRCLE OF HIS ANXIOUS FRIENDS, 



HE FOUND AN UNTIMELY GRAVE; 



'• Manibus date Liiia plenis; 



Purpureos spargam flores, animamque Jlmici 

 His saltern accumulem donis, et funnar inanj 



Mnncrc."
