    instrument can be made portable, the fixed arm, or that most distant from the handle, being removable, and the sliding arm following it; both can thus be placed in a case by the side of Fig. 2. Oraniometer: one fiftli the actual size. the stem ; but for museum or laboratory v\^ork the perfect stability of a fixed instrument is preferable. To avoid the labour of making innumerable calculations vnth risk of error in every case, tables have been constructed for finding the principal indices, w^hich are more convenient for reference and more exact than any of the mechanical instruments devised for the purpose. As such tables will be found useful by all who are working at craniometry in this museum or elsewhere, they have been printed at the end of the catalogue. The principal one, that for the length and breadth indices, is almost identical with that published by Welcker *, which was not known to me until after the present one was computed ; but as that table is not at present very accessible, and also contains several slight errors, it has been thought that the reproduction of a similar one in this work would still be acceptable. In these indices three figures have been given, the last, how- ever, as mentioned above, always modified in reference to the one which succeeds it. These, as they stand, may be considered as thousandths, but by placing a dot after the second or first figure they may be converted into hundredths or tenths if desired. The frequent practice in France of giving four figures for indices, * Ai'chiv fiir Anthropologie, Band iii., 1868.
