By such a summary as is here given, of course only the gene- 

 ral differences in the seasons are brought to light ; but our 

 readers will probably admit that the greatly increased labour of 

 examination, were the table more extended and in detail, would 

 scarcely be compensated for, if the main characters, recj[uisites, 

 and offices of the tui'nip season can be ascertained without it. 



A relatively large number of rainy days, an enhanced actual 

 amount of rain, and a low degree of temperature, are prominently 

 the characters which distinguish the assumed turnip season of 

 1845 from that of the two preceding years, and during a con- 

 siderable portion of the period, especially, from that of 1843. 



Thus taking the items somewhat in the order in which they 

 are given^ we find that in the latter half of the month of July, 

 upon the character of which so materially depended the early 

 development of the plant, and on this its future growth, in the 

 seasons of 1843 and 1845 the temperature was lower than in 

 1844 ; and in 1845 the number of rainy days is more than double 

 that in 1844, though somewhat less than in 1843, whilst the total 

 amount of rain was much greater in 1845 than in 1844, and 

 nearly equal to that in 1843. In August we have in 1845 the 

 lowest temperature, the greatest number of rainy days, and, 

 though not the largest actual amount of rain, a C|uantity large 

 compared with 1844, though below that in 1843. September 

 indicates still the lowest temperature in 1845, a number of rainy 

 days equal to 1844 and far exceeding 1843, and also the largest 

 actual amount of rain. The month of October, on the other
