It is proposed to continue the ‘ Refugium’ in the following manner. 
Part I. Vol. ii., already in the press, containing Orchids by Prof. Reichen- 
bach, will be published as soon as possible; and it is intended to devote 
the whole of Vol. 11. to plants of the natural order Orchidacere. Part I. 
Vol. iii. is in preparation, and will be shortly in the printer’s hands. The © 
Parts constituting this Volume will contain plants other than Orchids, and 
will appear alternately with those of Vol. i1., and at intervals of about 
four months.
