strumous swellings, is now for the most part diverted 

 into the spinal marrow, so that the strumse deprived 

 of nutriment, soon dry up. 



4. The bones are always more or less bent in this 

 disease, particularly the bones of the leg and of the fore- 

 arm. The joints also are often inclined outwards ; the 

 extremities of the ribs, where they join with the carti- 

 lages of the sternum, are nodose ; the bones of the 

 joints are protuberant ; also the whole spine is bent 

 variously, here outward, here inward. I do not think 

 that this curvature of the bones is owing to their flexi- 

 bility, because the children afflicted with this disease 

 have rather larger and firmer bones than others, as will 

 later be shown at some length ; yet as this curvature of 

 the bones is very notable, I may be allowed to discuss it 

 somewhat more fully, ^and I shall first give the learned 

 Dr Glisson's opinion, and then shortly state my own. 



Dr Glisson says : '' Let us compare the bones which 

 are apt to be curved to a pillar ; and indeed we 

 may do so quite properly, for if they are erect, they 

 correspond to a sort of pillar, and thence we deduce 

 a demonstration explanatory of this circumstance : 

 let, then, ^, h^ c (Plate IV., Fig, i) be a pillar com- 

 posed of three stones placed one on the top of the 

 other ; we shall suppose it such that every side is 

 perpendicular and of the same height ; if, then, we 

 insert a wedge on the right side between the stones 

 a and Z>, along the line /, ^, the head of the pillar, 

 that is, the highest stone, will be inclined towards 

 d^ and make an angle at d^ and the height of 

 the pillar will be greater on the right side than on 

 the left, as is shown in Plate IV., Fig. 2. Similarly, 

 if you push in another wedge along the line g^ <?, 

 between the stones h and c^ the pillar will be still 

 further inclined, and there will be an angle at e. The
