EDITORIAL NOTES, 



Owing largely to the inclemency of the weather, there 

 has been little or no improvement in the Editor's health, 

 and he is therefore once again compelled to claim indul- 

 gence for any shortcomings. 



The British Fern Gazette, Vol. 2, Nos. 13 to 

 24. — The Editor would again remind members that a 

 small number of Vol. 2 were bound into a very pre- 

 sentable volume of 313 pages and numerous illustra- 

 tions. As no reprint will be available, and the books are 

 widely recognized as most valuable contributions to our 

 Fern literature, the opportunity of acquiring copies, even 

 extra ones, should not be lost sight of. The price to 

 members is 3s. gd. post free, and speedy application is 

 advisable to secure, as very few are left. 



The subscriptions for 1916-17 being due in advance, 

 the Hon. Secretary would feel much obliged by a 

 remittance of 5s. by return post to 11, Shaa Road, 

 Acton, London, W.
