X. — A Calendar of Natural Periodic Phenomena: kept at Bodrrdn, 

 for the year 1866. — By Thomas Q. Couch. 



"II semble, en effet, que les phenomenes periodiqnes forment, pour les 

 §tres organises, en dehors de la vie individuelle, une vie commune dont on 

 ne peut saisir les phases qu'eh I'etudiant simultanement sur toute la terre." 

 — Quetelet. 



N.B. — ^The Names printed in Italics indicate plants and animals 

 marked for special observation. 



fl. means flowers ; fol., foliates ; defoL, defoliates. 



The time of flowering is to be noted when the flower is suffi- 

 ciently expanded to show the anthers ; of foliation, when the leaf- 

 bud is so far open as to show the upj)er surface of the leaves ; of 

 fructification, at the period of dehiscence of the pericarp, in de- 

 hiscent fruits ; and, in others, when they have evidently arrived 

 at maturity ; of defoUation, when the greater part of the leaves 

 of the year have fallen off".
