inference of causation may be allowed, in the manner and wkfa the 

 exceptions before more fully explained. 



This analysis of the nature and cure of diseases has been at- 

 tempted in conformity with those doctrines of causation, the ap- 

 plication of which has been said to be universal. It is impossible 

 to make a view so complex, embracing so many topics, appear 

 simple, and at first sight intelligible. I have traced the processes 

 of nature in this sketch, with a minuteness which ou untried 

 ground can scarcely be exceeded. Nature is said by some to 

 be very simple in her operations: she is simple enough to one 

 who contemplates things in the gross; whose sum of philosophy 

 consists in stating results, without troubling himself about the 

 machinery by which they are accomplished. If this analysis of 

 disease should be reproached as obscure, I say the obscurity be- 

 longs to the subject. I wish it had been possible to make it clearer: 

 but if the same objects should be attempted by one who would 

 make this obscurity a reproach, he would rind it difficult to give 

 a readily intelligible account of them, though this subject alone 

 should be drawn out to the length of a respectable volume.
