§ 6. Postscript. 



Art. 1. The foregoing Report is that which was presented to the Brighton 

 Meeting in 1872, considerably enlarged. After the Meeting it seemed de- 

 sirable to extend some of the articles in § 3, and to add descriptions of several 

 works to § 4 ; and it then appeared that the Report was so lengthy that it 

 was thought better to delay its publication till the ensuing volume, so as to 

 afford time for its passage through the press without undue haste. The 

 printing therefore was commenced in February or March, and is now 

 (September 30, 1873) all but finished. It was arranged, as the completion 

 of the Report by a supplement depended in great measure on the coopera- 

 tion of others possessing information on the subject of tables, that a certain 

 number of separate copies should be placed in the hands of the Committee, 

 as soon as the printing was effected, for circulation amongst those interested 

 in the matter, so as to avoid the delay of a year that would otherwise take 

 place before the work undertaken by the Committee became known to those 

 who could render assistance. 



Art. 2. While the Report has been passing through the press a good many 

 alterations have been made which were necessitated by increased informa- 

 tion on the subjects treated of, and by repetitions &c. which were detected 

 for the first time when the whole appeared in print. But no attempt has 

 been made to increase the extent of the Report by introducing descriptions 

 of fresh works ; in fact only about a dozen have been added since the 

 Brighton Meeting, and but four or five since the MS. was placed in the printer's 

 hands. 



The tendency of the Report has been fi-om the first to become more and 

 more bibliographical. Originally it was intended to introduce nothing of a 

 bibliographical nature ; but experience showed that this was impossible, and 

 attention to such matters has been continually forced upon us. A report on 

 tables differs from a report on any other scientific subject in this — that 

 whereas in a progressive science the earlier works become superseded by
