INSTRUCTIONS. xxx j 
No special directions are thought necessary in regard to the mode 
of conducting the scientific researches and experiments which you 
are enjoined to prosecute, nor is it intended to limit the members of 
the corps each to his own particular service. All are expected to 
co-operate harmoniously in those kindred pursuits, whose equal 
dignity and usefulness should insure equal ardour and industry in 
extending their bounds and verifying their principles. 
As guides to yourself and to the scientific corps, the Department 
would, however, direct your particular attention to the learned and 
comprehensive Reports of a committee of the American Philosophical 
Society of Philadelphia, the Report of a Committee of the East India 
Marine Society, of Salem, Massachusetts ; and to a communication 
from the Naval Lyceum of New York, which accompany, and are 
to be regarded as forming a part of these instructions, so far as they 
may accord with the primary objects of the Expedition, and its 
present organization. You will, therefore, allow the gentlemen of 
the scientific corps the free perusal of these valuable documents, and 
permit them to copy such portions as they may think proper. 
The Russian Vice-Admiral Krusenstern, has transmitted to the 
Department memorandums relating to the objects of this Expedition, 
together with the most improved charts of his atlas of the Pacific 
Ocean, with explanations, in three volumes. These are also confided 
to your care ; and it is not doubted that the friendly contributions of 
this distinguished navigator will essentially contribute to the success 
of an enterprise in which he takes so deep an interest. 
You will prohibit all those under your command from furnishing 
any persons not belonging to the Expedition, with copies of any 
journal, charts, plan, memorandum, specimen, drawing, painting, 
or information of any kind, which has reference to the objects or 
proceedings of the Expedition. 
It being considered highly important that no journal of these 
voyages, either partial or complete, should be published, without the 
authority and under the supervision of the government of the United 
States, at whose expense this Expedition is undertaken, you will, 
before you reach the waters of the United States, require from every 
person under your command the surrender of all journals, memo- 
randums, remarks, writings, drawings, sketches, and paintings, as 
well as all specimens of every kind, collected or prepared during 
your absence from the United States. 
After causing correct inventories of these to be made and signed
