Incidentally we notice some incidents sadly out of harmony 
with Waterton’s assertion that serpents never take the offensive 
or pursue a foe. 
Concerning the question “ Do snakes afford a refuge to their 
young ? ” Miss Hopley gives an answer in the affirmative. 
Bringing our short notice of this volume to a close, we must 
say that it has given us no small pleasure. We believe that, if

In treating of the stage of the microscope it is a singular 
omission that no mention should be made of the concentric 
rotating stage, which, owing to the advocacy of Dr. Carpenter
