The reader will have gathered from the foregoing that 

 we have no really diagnostic symptoms of ruptured 

 stomach. General F. Smith sums the matter up thus : 

 ' Diagnosis of this affection is anything but easy ; we

 most likely to ask, however, is this : ' What dependence 

 am I to place on the symptom of vomiting ? When 

 vomiting occurs, am I to positively declare my case one 

 of rupture?' Owing to this vomiting question being a 

 much vexed one, several facts stand out with greater 

 distinctness than they otherwise would have done. For

1. That cases of rupture occur in which vomiting is a 

 most marked symptom. 



2. That cases of rupture occur in which vomition is

 there was no rupture. 



It follows from this that vomition is not absolutely
