NOTICE. 
-^O*— 
The General Index to the Reports from 1861 to 1890 consists of one 
part only, and thus differs in an important manner from the Index to the 
first thirty volumes, which is composed of six separate divisions. As in 
the previous Index, all the members of a committee have been quoted as 
authors of the report of that committee. 
Errors which have been detected in the titles of papers or in the 
names of authors have been corrected in the Index. The authors of 
these papers have been communicated with in all cases where it has been 
possible. 
The references to reports and papers printed in extenso are given in 
italics, while the more numerous references to abstracts, or to titles only 
of papers, are in Roman characters. 
An asterisk * indicates that the title only of the paper is given. 
The mark t also indicates that the title only is given, but with a 
reference to the journal or newspaper in which the paper is printed, 
generally, in extenso. 
Initials or names placed within square brackets [ ] indicate a change 
in the author’s title.
