Natural Calendar of Coincidence. 19 
immediately connected with my present purpose, are some 
remarks by Mr. Lees (Vol. I. p. 200.), who suggests the idea 
of forming “a calendar by which the flowering of a plant 
should acquaint us with the appearance of a bird, and the ap- 
pearance of an insect tell us the flowering of a plant.” ‘The 
plan proposed by Mr. Lees strikes me as one full of interest 
to a lover of nature. Something of the kind, some affinity, 
connection, or coincidence, between the sever: Ei occurrences In 
one department of risieurrel history and those in another, must 
almost unavoidably have presented itself to the mind of the 
most transient observer. I wish you, or some one of your 
correspondents, would take the hint, and construct such a 
calendar. In the mean time, till some one better qualified for 
the task presents himself, I beg to offer to your notice the follow- 
ing sketch, by way of specimen. Of course a calendar of this 
land may be filled up and pee to almost any extent. The 
following is proposed as a mere outline, I am aware a very 
imperfect one, of the sort of thing intended, and contains only 
a few of the different occurrences in nature, which happen to 
have more particularly and forcibly struck my own mind as 
coinciding with each other. When I speak of such natural 
occurrences coinciding, it is not meant that they fall exactly on 
the same day of the month ; it is quite enough for our purpose, if 
they take place about the same time, if the things placed parallel 
to each other in the two columns are usually i in season toge- 
ther. The arrival and departure of birds, the appearance > of 
insects, and the flowering of plants, will in each year depend, 
in some degree, on the weather; and a variation of at least a 
fortnight or more may fairly be calculated upon, according to 
the forwardness or backwardness of the season. No eveater 
precision of date, therefore, is attempted, than such as may 
be attamed by noting the beginning, the middle, and the end 
of the month. The Linnean names of insects are for the 
most part employed below, which being generally understood, 
and perhaps more popular, seem better adapted to the present 
purpose, than the improvements of modern nomenclature.
