2nd. The glazed earthen jar placed under the porous bottom 

 of the cylinder to catch the filtered liquid, had, at the time the 

 fungus originated, a considerable quantity of dark saccharine 

 matter resembling concrete molasses therein ; this was suffered 

 to remain as a negative test to the electrical character of the 

 fungus, presuming the latter to have had its beginning in a por- 

 tion of sugary deposit derived from the solution through the 

 porous diaphragm ; yet, though the surface of the residuum in 

 the earthen jar presented the usual indications of mouldiness, no 

 appearance of a fungoid kind, or that of minute vegetation, could 

 at any time be detected within the unelectrified jar. 



3rd. The commencement of the fungus at a point precisely cor- 

 responding with the negative pole of the arrangement, its luxuriance 

 and maturity in the intermediate space on the glass cylinder, and 

 its decay on finally reaching the positive side, are in themselves 

 facts pleading strongly in favour of electrical influence over the 

 organization of this remarkable species of vegetation.
