in Helsingfors. The plants came under treatment in such 
a way that half a garden bed of about 7 metres (23 feet) 
in length was under the current, the other half serving as 
“control.” The following are the results in percentages :—

A singular circumstance was that we could not, during the 
summer, see any difference between the experimental and 
the control field,and we were on the point of believing that 
no difference at all would appear in the harvest, but, from 
the table above, it seems that the difference was very great. 
The most remarkable fact in this table is that some of 
the plants seem as though favoured by the electricity while 
others derived no benefit and were apparently injured by it. 
Among these last mentioned cabbage is prominent. It is, 
however, not necessary to discuss this inequality here, as it 
was later discovered that it had its cause in the want of water. 
The strawberries, planted in pots, were in a greenhouse 
and ranged in three compartments, separated from each 
In every compartment were 
two pots, and in the first + electricity in the second —(E) 
was given, the third being without E. The berries ripened 
in the first batch in 28 days, in the second in 33 days, and in 
the third in 54 days. The effect of the current was, there-. 
_fore,toshorten in an astonishing manner the time of ripening. 
Here we have a marked difference between the +E and the 
other by walls of cardboard.

Inthe same summer (1886) a first experiment was per- 
formed on the estate of Brédtorp, in the parish of Pojo, in
