110 THE LAWS OF ORGANIC

 riod that the regular internal circulation begins to 

 establish itself ; and when the frame is so con-

 itself as it did in the former instance ? the answer 

 to this is simple, the natural vascularity of the 

 surface of the body no longer exists : it is trans- 

 ferred more particularly to the internal organs ; 

 and whenever this normal modification is excited by 

 any of the causes which promoted the former disease, 

 the demand is made upon the lungs, as being the 

 most vascular, the most delicate, and, from their 

 situation, bearing the nearest relation to those parts 

 which are oppressed, or rather to that state of the 

 circulation which is to predominate till the decline

CIX. The sensible and delicately formed frame 

 of the female is protected, to a very great extent, 

 from such disorders. Nature has been extremely 

 provident in preserving this part of the creation 

 from derangements to which her constitution 

 would be unequal. When we are suffering from 

 changes in the mode of circulation, which the
