A CALL TO PHENOLOGICAL OBSERVERS. 
Dr. H. Hoffmann and Dr. E. lime, of Giessen, desire that 
all who take an interest in observing the influence of the 
seasons upon the vegetable world will devote themselves to 
ascertaining, as exactly as possible, the required particulars 
concerning the undermentioned plants, especially the first 
flowering and fiirst ripening of fruit. The observations are to 
be made upon normal plants ; those trained in any way (as in 
a garden) or exceptionally situated in a sheltered or exposed 
situation are to be disregarded. It is also desired that the 
observations may not be confined to the same plant each 
year, as the object is to obtain a trustworthy mean for each 
locality.
