 actual illness ensues, whenever the normal quantity is not 

 supplied. Examples of this are offered by the varying 

 quantities of iron contained in the blood (for instance its 

 deficiency in chlorosis), and by the different quantities and 

 qualities of the earths of the bones, in diseases of the osseous

 us that, having remarked, " Many facts which appeared to be

To consider the validity of his objections, it was agreed that
