NOTES. 
Material for Demonstration of developing 
Embryos (Klugia). 
Better material for class demonstrations of the stages in develop- 
ment of a dicotyledonous embryo than the Ceylon species of Klugia — 
Notoniana and zeylanica — it would be difficult to find. By taking 
seeds from capsules of all ages from those where the corolla has just 
fallen to those that are all but ripe, and mounting in eau de Javelle, 
the whole series of stages is easily demonstrated much more clearly 
than in most of the plants used for class work. The embryo can be 
seen in all stages from eight cells onwards, with its suspensor, gradually 
filling the embryo sac and seed. The embryo sac, tapetum, nucellus, 
and integument show with extraordinary clearness, and the gradual 
destruction of the nucellus and endosperm can be easily seen. The 
plant is well worth cultivation in Europe, where K. Notoniana should 
succeed in wet soil, well drained, with a fairly steady temperature of 
about 60° F.

The New Laboratory at Hakgala Garden. 
This building has been completed, and is now ready for work. It 
lies in an open site on the patana south of the cultivated part of the 
garden at an elevation of 5,580 feet above sea level. There is a 
laboratory room facing north measuring 21 feet by 13 feet, with two 
large working places, a herbarium of the hill flora, a small collection of 
books, and simple essentials for botanical work. Opening from it is a 
somewhat smaller living room, and beside this are two single bedrooms, 
with a kitchen and room for a servant. The building is of wood, with 
stone pillars raising it above the ground, and with fireplaces. It is 
being furnished with all necessaries, except linen and cutlery. Visitors 
must take their own servant to do the cooking and general attendance. 
There is a charge of one rupee a night for the use of the building to 
visitors not belonging to the Scientific Staff of the Department, who
