ARTICLES IN JOURNALS. 287 



Then there are persons who index matters under the definite 

 and indefinite adjectives : in fact, there is no end to the misplaced 

 ingenuity which index-makers have displayed, apparently with the 

 object of showing how useless an index can be made. 



The Linnean Society's Journals have exemplified both the 

 inadequate and superfluous kinds of index ; and it was high time 

 that some one should have produced a satisfactory substitute for 

 these. No one more fitted for the task could have been found than 

 Mr. Daydon Jackson, who is a born indexer — we sometimes think 

 that indexers, like poets, are born, not made — and who has, we are 

 sure, entered upon his task with a zest which must have relieved it 

 of much of its monotony. Every item is arranged in one alpha- 

 betical series — a benefit for which only those who have been 

 condemned to consult indexes of many alphabets will be suffi- 

 ciently grateful. Even those who do not possess the whole series 

 of the Society's Journals and Proceedings, will be glad to have at 

 hand a trustworthy record and indication of what has appeared in 

 them. Mr. Jackson has done much good work since he has filled 

 the post of Secretary to the Linnean Society, but he has under- 

 taken nothing more useful than this. If some day the Society 

 should see its way to issue a list of its Fellows aud Associates 

 during the first hundred years of its existence, which would, we 

 think, be of interest to many, we trust the task will be placed in 

 Mr. Jackson's hands.
