MATTERS IN APPENDIX. 261 



The Orders of the principal Expeditions are annexed, 

 in the Appendix, that the nature of the service required 

 of the successive Commanders may be fully understood. 



The remaining part of the Appendix is devoted to 

 subjects of natural philosophy, tabular matter, and na- 

 tural history; which will, I trust, evince that, notwith- 

 standing the great and absorbing duty committed to my 

 direction, the general pursuit of science has not been 

 disregarded.
