Prefatory Note with regard to the Supplements of 
the Annals of the Royal Botanic Gardens, 
Peradeniya. 
r 
It is proposed to publish in tlie form of Supplements to 
the Annals certain pieces of useful work more of the nature 
of compilations than of original scientific work : for example, 
the present Handbook of Economic Products, a revised List of 
the Flora of Ceylon, &c. The Supplements will be included 
in the subscription to the Journal, and portions of them will 
appear as ready. They should be detached from the rest 
before binding, as they are separately paged with a view to 
being separately bound when complete. A few extra copies 
of each portion are printed, and when complete will be sold 
as separate works at a considerably enhanced price. Frag- 
ments will not, as a rule, be sold separately, but may be 
obtained by purchasing the whole number in which they 
appear. 
It is not intended that the number of Supplements shall 
exceed the number of volumes, though it is probable that 
the publication of a second supplement may commence before 
the first is complete.
