 and if the action of either of these agents can be destroyed, 

 the decomposition is more or less retarded, as in bodies 

 inclosed in wax or coffins, where the action of the external 

 air is excluded : and when the action of both these causes 

 can be prevented, the body defies decomposition, as in 

 bricks and burnt bodies, where the vital spirit is expelled, 

 by exposure of the clay to the ambient air, and afterwards 

 by fire ; or as a fly in amber, more beautifully entombed 

 than an Egyptian monarch. 



In making the agents less predatory, and the patients 

 less depredable, the science of the retardation of consump

He proceeds, therefore, with his usual accuracy, to 

 consider how these objects are to be attained; and, having
