340 IMPORTANCE OF REGISTERS 



progress as the seasons advance, as those which 

 would have an especial interest, and which would 

 perhaps be the simplest to determine. 



(6.) Having made these remarks on the uses to 

 which we may apply a calendar of the principal 

 periodic phenomena in the vegetable and animal 

 kingdoms, we may go on to state, in a more methodi- 

 cal way, what sort of phenomena it may be desirable 

 to record, as well as to mention certain consider- 

 ations which should be attended to by the ob- 

 server. 



(7.) The naturalist who collects such dates simply 

 for his own use, and in order to perfect as far as 

 possible the history of that particular class of ani- 

 mals or plants which is the object of his studies, or 

 such history as connected with the particular dis- 

 trict in which he resides, is differently circumstanced 

 from him who has more general purposes in view. 

 Such an observer is independent of other observers. 

 He may make his own selection of the facts he is to 

 notice, or rather he will try to get together all the 

 facts of a periodic nature to which he can have 

 access. It may, nevertheless, assist him to have the 

 principal of these phenomena classed to his hand 

 under their several heads, in order that he may not 

 overlook any, and that his observations also may 

 assume more of a systematic character. With this 

 view, we have drawn up the following tabular 

 arrangement of such periodic phenomena in the 

 animal and vegetable kingdoms as appear most 

 worthy of record.
