think, at least two hours to the subject weekly during thirty weeks. There is the 
additional serious difficulty that the specimens used in the earlier lessons can only 
be had in the spring or summer. If the Department truly wishes for an improve- 
ment in elementary botanical teaching it must alter the date of its examinations 
from May to December. An untrammelled teacher need desire no better 
elementary manual than this ; and the illustrations, as may be seen from the two 
which, by the courtesy of the publishers, we are able to reproduce, are as novel
