Anr. VI.—On the e Extrication of the Alkalifiable Mente Bari- 
um, Strontium, and Calcium ; by Rosert Hare, M. D., Pro- 
fessor of Chemistry in the University of Pennsylvania. 
‘be Read before the American Philosophical Society, October 4, 1839. 
In the autumn of 1820, I devised an innovation in the mechan- 
— ism and i in the mode of completing the circuit of an extensive vol- 
taic series. Previously to that time, in using any form of the vol- 
taic battery, the circuit had sipeiaienn completed by making a 
é communication between the electrodes,* after the submersion of 
the plates. In the case of the deflagrator, the electrodes might 
be made to communicate before the immersion of the plates, the 
Circuit being completed by their immersion. Or, in case the elec- 
trodes should not be in contact before immersion, the operator was 
enabled to bring them together so nearly about the same time, as 
toavail himself of the pre-eminently energetic action which im- 
mediately succeeds the encounter between the plates and the 
vent. 
Fourteen years had elapsed, during which I had the regret of 
perceiving that the advantages of the deflagrator were not sufli- 
ciently estimated in Europe, when, about the year 1835, the cel- 
ebrated Faraday,+ while investigating the principles upon which 
galvanic apparatus should be constructed, came to a conclusion 
* Agreeably to the suggestion of Faraday, I use the word electrode, for the pole of 
a Voltaic series ; also ano ode, for the positive pole, and cathode for the negative pole.
