COINCIDENT DEVELOPMENT. 273 



inquired as to some points concerning time and 

 quantity. Now, as to the attribute Kind, I have 

 no suggestions to give here as to the essential 

 character of kinds of growth. Observation shows 

 that the kind of growth occurring in a part of the 

 body may be good, bad, or indifferent. It generally 

 happens that if the growth of parts of the body 

 that can be seen is good, the growth of organs 

 that cannot be seen is likewise good. This is an 

 empirical statement. 



This leads us to study a mode of expression 

 referred to in chap. iii. p. 42, under the term " Coin- 

 cident similar development." 



It often happens that after extended observation 

 we find the condition of growth or development 

 of one part of the body expresses, or indicates, the 

 presence of certain properties in the subject not 

 directly connected with the special sign observed. 

 Dull heavy-looking features usually accompany a 

 dull inactive mind (brain), not because the dull 

 features cause an inactive condition of mentation, 

 but because this cast of features usually accom- 

 panies a make of brain with slow action. This 

 mode of expression is, then, indirect and empirical ; 

 in many examples no causal connection can be seen 

 between the two subjects of similar growth. In 

 an Englishman excessive development of the epi- 

 canthic fold of the eyelids (chap. vii. p. 137) is often 

 accompanied by mental dulness ; here, then, there 

 is similar bad development in eyelids and in brain. 

 The want of symmetry of bilateral or correspond- 

 ing parts often indicates poor development of
