METHOD OF STUDYING MATEEL 



If the study of structure is to be most effective in 

 producing a clear mental picture in which or to which 

 parts and functions are related, it must be orderly. 

 In previous steps there should be an order or sequence, 

 but conditions must largely determine that order. In 

 studying or describing form or structure the order 

 must be determined 

 by the order followed 

 by the mind in mak- 

 ing a mind picture 

 of form or structure. 

 We appreciate and 

 realize best the pro- 

 cess in marking a 

 mental picture when 

 we attempt to draw 

 from a description 

 what we do not see, 

 a spider, for in- 

 stance (see Fig. 22). 

 If, as we stand be- 

 fore our pupils ready 

 to make on the black- 

 board a picture of the spider from their description, we 

 are told first that the spider has eight legs, or that it 

 has several eyes, or that it has a pair of feelers (palps) 

 in front of its head, we cannot draw, we cannot place 

 the legs or eyes or feelers, or relate them to the whole 

 spider. They must tell us first about the spider as a 

 whole, and about its body, the part to which legs and
