Dr. Pearson’s Experiments , See. 
by the most rigorous reasoner, to be demonstrative that hydro- 
gen and oxygen gaz were produced by passing electric dis- 
charges through water. 
With regard to the origin and mode of production of these 
two gazes, our present observations and experiments do not 
afford complete demonstrative evidence; but, although some 
hypotheses must be admitted, I conceive that the body of evi- 
dence we possess can afford a satisfactory interpretation of the 
phenomena. 
EXPLANATION OF THE PLATE (Tab. III.) 
Fig. i, 2, 3, 4. represent the tubes used in producing gaz 
from water by the interrupted electric discharges. 
Fig. 5. represents the situation of the above tubes during 
the process of producing gaz from water. 
Fig. 6 , 7. represent the tubes employed in producing gaz 
from water by the first method, with uninterrupted electric 
discharges. 
Fig. 8. shows the figure of the tube mounted with a brass 
funnel, used in the second method of producing gaz from wa- 
ter by uninterrupted electric discharges. 
Fig. 9. represents the tube blown funnel-wise at the end, 
instead of being mounted with a brass funnel, as in fig. 8. 
Fig. 8. represents the situation of the tubes fig. 8. and 9. 
during the process of producing gaz by the uninterrupted elec- 
tric discharges.
