position, frequently cause two, tliree, or eveu more days differ- 

 ence, between tlie epochs of tlie same event in trees or plants of 

 tlie same species, very near one anotliei-. It will genen.lly be 

 found that these diflerences are constant. An early and a late 

 specimen should be selected. There is also a considerable inter- 

 val between the opening of the first flowers on shrubs — like the 

 Lilac, Almond, etc., — and any general display of blossom — both 

 peiiods should be observed. It should be added, when the 

 flowering is completely over. Again, it is not altogether easy to 

 dec-ide, exactly, when leaves are to be considered fully expanded : 

 the observer should note the date at which it can be fii-st asseit- 

 ed doubtfully, and when it is past a doubt. Remarking also the 

 condition of the weather, which may be supposed to hasten or 

 retard the phenomena. Such as a prevalence of fine or cold 

 days, about the time each is expected — warm or cold rains — • 

 high winds, and so on. Lastly, no observer can be certain that 

 his observation is the firet that might have been made in the 

 neighbourhood, and a considerable number of independent re- 

 cords must be consulted to fix the epochs exactly.

FIFTEENTH ORDINARY MEETING. 



AXNUAL CONVERSAZIONE. 



The very gratifying nature of the j>roceedings at the Annual 

 Conversazione of the Institute, held in the Hall of the Legislative 

 Assembly, on Saturday, April 2nd, induces us to adopt a method 

 of recording them, which savours less of originality than of 

 respectful submission to the opinions of the Press, as shown in 

 the very flattering descriptions which wo beg leave to subjoin : 

 (From the North AmericoTi.) 



" On Saturday evening the most interesting. Literary, Scien- 

 tific, and Pleasurable meeting ever witnessed in Toronto, was 

 held in the Legislative Assembly Hall. — It was the Amiual Con-
