NOTICE. 



On account of the difficulties met with in full}' organising- the work 

 of the Regional Bureaus, the collection of the material for the year 

 1901 has been somewhat delayed. It has therefore been thought 

 desirable to issue iucomplete volumes for some of the subjects. 



The first part of the Botan}' Volume is now issued, and it will be 

 followed in the course of a few months by a second part. 



It is intended that in future years, when the org'anisation for the 

 collection of the index material has been fully developed, onl}' one 

 volume of Botany shall appear in each year.
