way,* but it would require the cooperation of many 

 observers to arrive at any useful or trustworthy con- 

 clusions. Nevertheless, the subject is worth attend- 

 ing to ; and if a natural calendar, constructed, as 

 some have proposed, after this manner, did not 

 entirely supersede the artificial one at present in 

 use, it might at least have a subsidiary value in 

 the case of some matters in husbandry and 

 gardening, calling for a more than ordinary regard 

 to the conditions of the soil, and the influence of 

 particular seasons. 



(5.) We come now to speak of another application 

 of the Naturalist's Calendar of Periodic Phenomena, 

 and one calculated to advance the ends of science in 

 a more general manner. This is its application to 

 the subject of the laws of climate, and at the same 

 time to many important questions in animal and 

 vegetable physiology. In reference to these ends, 

 it is requisite that such calendars be kept in differ- 

 ent places, upon a given plan, by as many different 

 observers as may be prevailed upon to join in the 

 inquiry.f When so conducted, as they have been 

 lately, according to a system to which we shall have 

 occasion presently to allude further, the results

 rium Flora, in the Amasnitates Academics ; both translated by 

 Stillingfleet, who has appended to the latter his own calendar. 



f Such calendars should be combined with observations in 

 Meteorology, according to the suggestion of Linnaeus placed at 

 the head of these remarks; Calendar ia Flora quotannis conficienda 

 sunt in quavis Provincia, secundum frondescentiam, efflorescent iam, 

 fructescentiam, defoliationem, observato simul climate, ut inde con- 

 stet diversitus regionum inter se. Philosoph. Botan. p. 276.
