 long array of maladies, such a host of symptoms, and such 

 a variety of " complications," that he is at first surprised, 

 when an actual case of the disease presents itself, that not 

 a quarter, perhaps, of the symptoms enumerated are really

The weakness of patent remedies in the light of such 

 considerations must be plain. There can, in the very 

 nature of the case, be, as a rule, no panaceas, no remedies
