And now having stated in general terms the aims of the laboratory and given some account of the progress in general, let me pass to some description of the means which have been placed at our disposal to realize those aims. Bushy House, Ground Plan. I here wish, if time permits, to discuss in fuller detail some of the work which it is hoped we may take up immediately.

The laboratory is to be at Bushy House, Teddington. I will pass over the events which led to this change of site from the old Deer Park at Richmond to Bushy. It is sufficient to say that at present Kew Observatory in the Deer Park will remain as the observatory department of the laboratory, and most of the important verification and standardization work which in the past has been done there will still find its home in the old building. The house was originally the official residence of the Ranger of Bushy Park. Queen Anne granted it in 1710 to the first Lord Halifax. In 1771 it passed to Lord North, being then probably rebuilt. Upon the death of Lord North's Bushy House, Basement. widow, in 1797, the Duke of Clarence, afterwards William IV., became Ranger. After his death in 1837 it was granted to his widow. Queen Adelaide, who lived here until 1849. At her death it passed to the Duc de Nemours, son of King Louis Philippe, and he resided here at intervals until 1896. In spite of this somewhat aristocratic history it will make an admirable laboratory.

The building is very solid and substantial. There is a good basement under the main central block with roof of brick groining, which makes a very steady support for the floor above.
