From these experiments it will be seen how very 

 great is the dissimilarity of the symptoms in difiFerent 

 cases of daboia-poisoning. Hardly any two cases are 

 alike. Thus, in Experiment I., the dog becomes gra- 

 dually paralysed, and dies of asphyxia. In Experiment 

 II. six minutes after being bitten it falls into severe 

 convulsions, after which it is found to be paralysed, the 

 paralysis ultimately stopping respiration. In Experi- 

 ment III. no change was observed for seventeen hours, 

 and then the animal died of lung complication. In 

 Experiment IV. in a minute and a half after being 

 bitten, the dog fell over in violent convulsions, and died 

 at once. In Experiment V. three minutes after being 

 bitten the dog had the most violent convulsions, to 

 which paralysis immediately succeeded, which became 

 mo^ and more complete till death. In Experiment VI. 

 there were convulsions, but they passed off, leaving the
