obtained nearly all the year at Calcutta, yet their 

 period of greatest perfection is from April to Septem- 

 ber. This may be termed their ripening or stove 

 period ; and it will be found, upon referring to this 

 table, that the average maximum temperature of that 

 period is above 9 1 degrees, and the average minimum 

 more than 79.

We may just observe that the above are average 

 temperatures, and that the pine apple in Bengal often 

 has to endure such widely differing temperatures as 

 129 and 53 degs. From these facts, we conclude 

 that if in England the temperatures each month 

 never ranged higher in the pinery than the minimums 

 in the above table, they would not be too high in 

 proportion to the diminished light of our latitude. 



The following are the night temperatures aimed at
