Describe it. Sketch it. 



(5) If possible note any differences between a fore and hind limb, 

 and draw both feet. 



SUGGESTIONS FOR FURTHER WORK 



Look at the skull of a hedgehog and describe the teeth. Find 

 out from your living specimens what they will feed upon, and see 

 whether the teeth are specially adapted for the work which they 

 have to perform. 



When opportunity offers, add notes as to the time of day at 

 which hedgehogs feed when wild, the time of year at which the 

 young ones are born, and their appearance.

Note : If the pupils cannot examine a horse during Lesson IX 

 they should, in the meantime, fulfil for themselves out of school 

 the instructions (see page 92) which refer to the living animal.
