28 Mr Smith's case of extraordinary developement 



ance to this boy, and suggests to the writer of this the idea 

 of the muscles having grown without a corresponding elonga- 

 tion of the bones. Hence the vasti externi, the deltoid, the 

 biceps, and supinator muscles, appear like huge lumps towards 

 the upper end of the bones. The penis and testes are as large 

 as those of most men, if not larger. The pubis is covered with 

 black curly hair. He has also short dark coloured mustachios, 

 but no hair on his chin. A sort of down, of the same light 

 brown colour of the hair of his head, appears in the place of 

 whiskers. His eyes are uncommonly sunk, and appear dull, 

 and somewhat inanimate. 



It is impossible, in a verbal description, to convey a just no- 

 tion of the appearance of this extraordinary boy. I therefore 

 send a correct sketch, see Plate I. which an eminent artist did 

 me the favour to make of him at my request. This sketch 

 presents a striking likeness, and gives a faithful representation 

 of the appearance and proportions of every part as seen in a 

 front view. 



To render my observations in respect to the organic develope- 

 ments as complete as possible I measured ihejucial angle^ and 

 found it to be 83°. It is obvious that this angle must be much 

 affected by the state of the frontal sinuses. In this boy, the 

 uncommon projection of the upper parts of the orbits of the 

 eyes, as well as of the lower part of the ridge running up the 

 middle of the forehead, suggest the idea of uncommon large- 

 ness of the whole frontal sinuses ; and this suggestion will be 

 still farther confirmed by the deep hollow tone of voice which 

 this boy has, if, as is commonly thought, the enlargement of 

 these sinuses is attended with that effect. If the quantity of 

 brain in the upper and anterior part of the cavity of the cra- 

 nium has any thing to do with the intellectual functions, as 

 some appear to think, there is another angle which it may be of 

 still more importance to measure than the facial angle of Cam- 

 per. The angle I mean is that which is formed by the meet- 

 ing of a line drawn along the base of the brain, with another 

 line drawn along the forehead, parallel to the inner table of 

 the scull. This may be called the hasi-frontal angle, and is 

 found to vary considerably in different persons. In persons 

 of undoubted great capacity, this angle has been found as high
