INTRODUCTION TO VOL. III. 



At the particular solicitation of some of the Subscribers to 

 this work, the plan of publication will be somewhat altered. 

 Instead of finishing one division of Ferns before commencing 

 a second, it is now proposed to publish three divisions of Ferns 

 at the same time; for it is considered that the interest will be 

 increased by the work being more varied. At the same time 

 the different divisions will be so paged, that when completed, 

 they will readily be bound up in their proper volumes. Each 

 volume will contain about 160 pages, and 75 coloured illustra- 

 tions, and the same number of wood-cuts. The work will 

 consist of 7 volumes. 



Vol. I. will contain Polypodium, Hypolepis, Nothoclcena, 

 Gymnogramma, fyc. 



Vol. II. — Go?iiopteris, Goniophlebium, Niphoholus, Cyrtople- 

 bium, Phlebodium, Dry?iaria, Acrostichum, 8fc. 



Vol. III. — Cheilanthes, Platyloma, Adiantum, 8fc. 



Vol. IV. — Litobrochia, Pteris, Lomaria, Blechnum, Doodia, 

 Woodivardia, Sfc. 



Vol. V. — Asplenium, Diplazium, Sfc. 



Vol. VI. — Aspidium, Nephrodium, Woodsia, Cystopteris, Las- 

 trea, Polysticlium, Nephrolepis, 8fc. 



Vol. VII. — Davallia, Dicksonia, Cyathea, Lygodium, Anemia, 

 Osmunda, 8fc. 



It is proposed to publish at the same time Vols. I, III, and 

 V. Vol. III. commencing with the Genus Adiantam, and Vol. 

 V. commencing with the Genus Asplenium.
