Dr Fyfe'*s Experiments on Electro-Culture. 149 



23c? June. — Peas near the zinc plate drooping. To try whe- 

 ther this was owing to the electric current or to the salt 

 alone, some salt was put in the earthnear the peas of ano- 

 ther row. 



12th July. — Two of the rows, not galvanized, in flower. 



15M. — A third row, not galvanized, in flower. Peas near 

 the salt last put in, drooping. 



\Qth. — Galvanized row in flower. After this, the peas in 

 all the rows advanced regularly, and, when inspected from 

 time to time, no diff'erence could be observed between the 

 diff'erent rows. 



ONIONS, 



16M June. — A bed of onions, which were sown some time 

 before, was weeded on the 12th June. They were about 

 three inches above ground, and very irregular. On the 

 16th, a zinc plate, with sea-salt, was placed in the ground, 

 at one end of the bed, and a copper plate at the middle of 

 the bed, at the distance of ten feet. They were connected 

 by a wire twenty feet in length, spread over the surface of 

 the ground in a tortuous manner, and lying in contact with 

 the leaves of the onions. The other half of the bed was left 

 without galvanic plates. 



23c?. — Can observe no diff'erence between the galvanized 

 and non-galvanized parts of bed. 



bth July. — No diff^erence observable between the diff'erent 

 parts of the bed. 



20M. — Onions not a good crop ; equally deficient in all 

 parts. 



At this time was recommended to water them with solu- 

 tion of nitrate of soda, with the view of destroying a small 

 worm with which they were infested. The solution waa 

 applied equally over the whole bed. 



1*^ August. — Onions continue to enlarge, though slowly ; 

 do not seem improved by the nitrate. 



lOM. — No diff'erence between the diff^erent parts of bed. 



After this they continued to grow without any observable 

 diff^erence ; and when taken up in October, there seemed no 

 diff^erence between those in the difi^erent parts, either as to
