74 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 
showed itself in slight retardation of growth, and the flowers opened 
four or five days later than untreated healthy bulbs. The treated 
healthy bulbs did not flower quite so freely as the untreated healthy 
bulbs, although the bulbs were of the same variety and of the same 
grade. 
The soaking of bulbs in water at a temperature of no° F. for a 
period of 2 to 4 hours offers many difficulties. The temperature of 
the water must remain constant and each bulb should receive the 
same treatment. In cases where the soaking must be performed on a 
large scale it cannot be recommended to immerse the bulbs in full sacks 
in tanks containing warm water, as it is evident that the bulbs situated 
in the centre of the sack will not receive the same treatment as those 
situated near the sides. Experiments on the soaking of bulbs in water 
at a constant temperature are to be carried out this season on a fairly 
extensive scale, with the hope of finding a suitable apparatus for the 
purpose. 
Soaking of Bulbs in Warm Solutions of Chemicals. 
In addition to the warm-water soaking experiments, bulbs were 
also treated with warm solutions of chemicals. The results are 
recorded in Table VI.
