months of the year, viz., November to February, and June 

 to September. I should not be surprised if it flowers in 

 other months as well. Of course it does not flower in all 

 these months every year. Again, turning to Tallow Wood, 

 Eucalyptus microcorys, I see it flowers in July and from 

 September to December. Some plants as the Native Rose, 

 Boronia serrulata, have, however, a very limited flowering 

 period in winter and spring as everyone knows. It is 

 therefore, difficult to construct a floral calendar at this 

 stage, but if I invite attention to the matter and secure 

 the co-operation of a large number of observers, I am sure 

 that in a few years, many of the difficulties of making a 

 list of plants in flower during certain months will disappear.

A.— Some of the earliest phenological observations are 

 probably those of Gilbert White made at Selborne, Dorset, 

 and those made by William Markwick at Oatsfield in Sussex, 

 from the years 1768 to 1793. They form an Appendix to 

 most editions of White's Selborne, where they are placed 

 in parallel colums for comparison. 



B.— Enquiry of the Director of the Phenological Office, 

 London, led Mr. R. G. K. Lempfert, Superintendent of 

 Statistics to refer me to the following list of papers in Prof. 

 R. de Oourcy Ward's translation (Macmillan) of Hann's 

 "Klimatologie," Vol. i, p. 90. As the work and the trans- 

 lation are so excessively scarce in Australia I quote the 

 bibliograpy here: —
