persuaded, it affords no benefit, having seen it 
largely tried by different practitioners in a number 
of fatal cases, where it only produced a distress-

The active properties of the Lobelia are readi- 
ly extracted both by water and aleohol. The tine- 
ture however is most easily kept, and is the most 
convenient form for exhibition. The Essex dis- 
trict medical society have recommended a formu- 
la for this composition, which directs two ounces 
of the dried plant to be digested in a pint of di- 
luted alcohol. Of this tincture, a teaspoonful giv- 
en to an adult, will generally produce nausea, and 
sometimes vomiting. In certain instances how- 
ever, much larger doses have been given, without 
producing any other effect than a flow of saliva.
