the case still more simple and the argument from it more con- 
vincing, only one of the three catalogues (. International A) has 
been taken advantage of. That is to say, all the mathematical 
serials have not been tabulated, but only those which find a place 
in the List of Journals published in 1903 in connection with 
the International Catalogue of Scientific Literature. Such a list, 
in view of its relation to the Royal Society of London, and in 
view of the fact that an international council stands sponsor for 
it, must be a list free from any grave reproach. 
In the next place, the chosen serials having been tabulated, 
copies of the table were made and submitted directly or indirectly 
to the librarians of the more important appropriate libraries in 
Scotland and in London, for the purpose of ascertaining exactly 
which of the serials each library was at the moment receiving, 
and what back volumes of these it possessed. The whole of the 
information thus obtained it is not proposed at present to use ; 
the portion of most value and interest here and now is that 
concerning Edinburgh and Glasgow.
