 are full 5 degs. too high, not only from our own ex-

 differ full 1 degs. above that of the night. We are 

 confirmed rather than shaken in this opinion by Mr.

 the external atmosphere, or any such cause which 

 may influence the air of the internal apartments ; a 

 few degrees up or down ; this variation, unless to a 

 great and unnatural degree, will in no way affect the 

 general health of the plants.
