been so mentioned, many of them referred to twenty times or 

 more. This index will probably be too bulky to bind with a 

 volume of the Bulletin, and will, therefore, be issued in a neat 

 paper cover. It will doubtless be sent free to members of the 

 Fern Chapter, and to others the price will be 25 cents. Those 

 who wish may order copies at once and be sure of receiving them 

 as soon as issued. It is the most complete index to the literature 

 of ferns ever published for a similar period.

As the series of articles upon the genus Bquisetum that has 

 been running for several years in this journal draws to a 

 close, we begin to appreciate the debt all fern students owe to 

 Mr. Eaton for so clearly and carefully distinguishing our forms 

 and species of this genus. Mr. Eaton is now at the Ames Bo- 

 tanical Laboratory, North Easton, Mass., where he is prepar- 

 ing a monograph on the Isoetaceae of North America, which we 

 may expect to be done in an equally careful manner. He is 

 desirous of examining all available material in Isoetcs and will 

 either return specimens submitted to him or send others in ex- 

 change, as the sender may direct. All students know the value 

 of having their specimens named by an authority, and it is hoped 

 that no one will neglect this opportunity to help Mr. Eaton while 

 verifying their own identifications. " 



So many people, in renewing their subscriptions to this 

 journal, have asked for a sample of the American Botanist that 

 we have ordered enough extra numbers of the January issue 

 printed to enable us to send a copy to every reader of the Fern 

 Bulletin who is not also a subscriber to the Botanist. The 

 editor asks that they be accepted with his compliments, and 

 trusts that they may prove of interest.

This issue has been unavoidably delayed. Contributors will 

 please send manuscripts early in order that we may be on time 

 with the April number.
