The index to the current volume appears in this issue. To those who are familiar with The Journal it needs no introduction, but for the new subscriber, or the old subscriber who has not familiarized himself with it, the following explanation may be in order:
The index is in three parts—the "General Index," the "Index to Subjects," and the "Index to Authors."

The "Index to Subjects," on the other hand, is an index of articles which have appeared in the most important medical journals of the world—including, of course, The Journal's own articles. This "Index to Subjects" is practically an index medicus, not so exhaustive or complete as the Index
