plants, are to be found under such a variety of forms, that 

 division into "species," as naturaHsts'lgenerally/use the word, 

 is ahnost a matter of degree.'*^ ,5f "^ 



Even Darwin^ who paid at least j^as]much|attention-^to the 

 subject as any man^has ever done, was unable to lay downjany 

 hard and fast rules as to where a line, so;to speak, was_jto be 

 drawn between one species and another, -"lit will usually be 

 found that the larger the area from which a student has made 

 his studies of the subject, the wider his views as to what "aggre- 

 gate of individtials " should be taken to constitute a species. The 

 collector in a small district has a much better chance of judging 

 whether two similar forms in that locality are really one or two 

 biological species than the one who merely examines material 

 collected by another. It is impossible to do more than merely 

 introduce this very old and extremely complex subject in the 

 space here available. 



THE FLETCHER MEMORIAL FUND. 



The following is a list of the subscribers to the above fund, 

 with the amounts subscribed set opposite each name. The 

 Committee feels that there must still be a goodly number of 

 friends of the late Dr. Fletcher who desire to contribute some- 

 thing towards the proposed memorial, before the list is finally 

 closed. Of the proposed forms of memorial, as stated in the 

 circular sent out bv the Committee, the one referring to the 

 erection of a Drinking Fountain at the Central Experimental 

 Farm has proved to be the most popular. Before the Committee, 

 however, can definitely decide, it is necessary to make a further 

 appeal to those who wish to subscribe something, but who have 

 not as yet notified the Secretar^^-Treasurer of the Committee, 

 Mr. Arthur Gibson, Experimental Farm, Ottawa. Any therefore 

 who desire to do so, will help very much in this work of the Club, 

 by attending to this matter at their early convenience.
