INTRODUCTION. 
B EFORE i fe t forth the Calendar of Flora* 
or the delights of the year, arifing from 
mere fublunaty things according to its progrefs, 
and that from obfervations made in the climate 
of Upfal, ann. 1755. i think it necefiary to fay 
fomething by way of introduction. Time moyes 
on flowly ; every thing is in progrefiion and mo- 
tion, and has its allotted time, as the wifeft of 
men Solomon obferves ; to which purpofe Virgil 
fays, St at fua cuique dies. 
Aftronomers have exerted all their power to mea- 
fure time. To them we ov/e the accurate dmlions 
of it; for they by obferving the courfe and mo- 
tion of the celeftial bodies, have been at laft ena- 
bled to reduce it to fcated periods, and to divide 
it in fuch a manner into years, months, weeks and 
days, that we have calendars conftruCted for com- 
mon ufe, as a rule by which to obferve and num- 
ber its equal parts. 
As theftars radiate, fliine, and adorn the celeftial 
regions of the fummer months, fo flowers beautify 
and illuminate the earth with a wonderful va- 
riety of bright and delightful colors. Thus, ac- 
cording to the ftile of the chyrnifts, that which 
is above is as that which is below. 
How much time foever and labor botanlfts 
have beftowed for many ages back, in order to 
know the names, nature and vertues of plants, 
they have not hitherto arrived at that degree of 
perfection, as to be able to equal the fuccefs of 
aftronomers, in noting the properties a&d phe- 
nomena of each of them.
