we make this last offer to complete files free. We want every 

 subscriber to have clean and complete files. Look through 

 3'our magazines at once, and if any copies are missing or 

 soiled we will replace them free if notified at once. To sub- 

 scribers, and to subscribers only, we offer any of the back 

 volumes at exactly half price, namely 25 cents a volume. This 

 offer is only made for 30 days and will not be renewed. The 

 seventy-five numbers already issued contain more than 1500 

 pages and at the price they may now be obtained, if ordered 

 at once, constitute the cheapest and best botanical literature 

 obtainable.

The Post Office Department has recently decreed that 

 publishers cannot legally carry unpaid subscriptions longer 

 than four months, thus putting an end to our well-known cus- 

 tom of allowing subscribers to pay each year when they chose. 

 Those, therefore, who wish to continue the magazine but do 

 not care to pay at once should send us word to continue. Such 

 notice for this and succeeding years may be given by simply 

 saying on a postal once for all "continue until ordered stop-

 pay up, since our only recourse in case they do not do so, is 

 to send the bills to an agency for collection. We trust they 

 will understand that such action is in no way a reflection upon 

 their honesty, but necessitated by the action of the Post Ofiice 

 Department. Those who notify us to continue may pay each 

 year when they please, as usual.

Much as we regret a change in the name of any plant, we 

 specially deplore the tendency to "honor" present day botan- 

 ists at the expense of those of another age. Instances of this 

 are found in the substitution of Porteranthus for Gillcnia. and 

 of Isoctes Brittoni for Isoetes Braunii. The instances can be 

 multiplied but the principle is the same in all. One of the most
