OUR FACE FROM FISH TO MAN 



thyroid gland, which would give him lateral 

 features, but owing to some environmental stim- 

 ulus, such as treatment with thyroxin, his thyroid 

 gland may be stimulated to greater activity and 

 to that extent his features may approach the 

 linear type. 



Another complication arises from the circum- 

 stance that the growing parts themselves show 

 different degrees of response or receptivity to the 

 hormones or growth-stimulating substances se- 

 creted by the ductless glands. In the dachshund, 

 for example, the bent legs resemble those of the 

 achondroplastic bulldog, while the long muzzle is 

 like those of ordinary large hounds (Stockard, 

 1923, pp. 269, 273). Whatever influence produced 

 the achondroplastic limbs would have produced a 

 bulldog-like head, if the growing head itself had 

 been receptive to it. 



One goal of scientific physiognomy would be the 



ability to control and regulate the environmental 



factors of growth to such an extent that hereditary 



defects in the facial make-up could be overcome; 



while a eugenic ideal would be to encourage the 



increase of strains tending to produce beautiful 



faces linked with high intelligence and moral worth.
