REMARKS. 



WHILE the sheets of the "List" were passing through the press, 

 the Author was unable, from absence, to revise the proofs, and it has 

 fallen upon me to attend to this portion of the work. Should errors 

 in reading be found, the Author must not be held responsible. As far 

 as known to me, all matter written or published up to Sept. 30, 1873, 

 has been incorporated. 



It is the intention of the publishers to issue at intervals (probably 

 annually) supplementary parts, to contain such additions and changes 

 as may occur ; and, as it may probably be my lot to furnish the manu- 

 script, I would feel greatly indebted for information concerning any 

 errors or omissions which may exist in the body of the "List." A 

 few striking errors are noticed on the preceding page.
