XVIIL—A Calendar of Natural Periodic Phenomena: kept at 
Bodmin for the year 1871.—By Tuomas Q. Coucu; F.S.A. 
‘Tl semble, en effet, que les phénoménes périodiques forment, pour les 
étres organisés, en dehors de la vie individuelle, une vie commune dont on 
ne peut saisir les phases qu’en l’étudiant simultanément sur toute la terre.” 
—Quetelet. 
N.B.—The names printed in Jtalics 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 upper 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 defoliation, when the greater part of the leaves 
of the year have fallen off. 
My observation of natural phenomena has suffered much un- 
avoidable interruption, and is therefore not so full as in preceding 
years. I have, however, done my best not to lose a link in the 
chain of record. A longer series is needed, and of course some 
years must elapse before I can generalize. I wish I could get skilled 
observers, around our coast and inland, to assist me in a work 
which is of no mean importance. The natural philosopher would 
find additional interest in his daily walk, and even the cut bono 
man would find value in its results. 
The year has been a very disastrous one in our district, as far 
as the human death and disease rate is concerned. Typhoid fever 
and Scarlatina have been prevalent and fatal, but, happily, are 
now almost gone. A few scattered cases of Small-pox have occurred
