Mr. Eric Hoghton has been appointed honorary Research Student 
in Electro-biology and is making active preparation to begin .his 
investigations as soon as the Laboratory is ready for use.

Winter-flowering Sweet Peas, Bearded Irises, Pyrethrums, Annual 
Sunflowers, Early and mid-season Potatos, Early Peas, Autumn

8. New Cottages. — The block of six new cottages for the Staff at 
Wisley is now completed and occupied. It will be found at the far 
northern end of the Gardens, where it forms an attractive group on 
three sides of a square, facing the road from Byfleet. 
9. Entomologist. — In the spring of the year the Society's Entomo- 
logist, Professor Maxwell Lefroy, M.A., was temporarily released from 
his duties at Wisley to enable him to undertake, on behalf of the War 
Office, an investigation into the means of destroying the eggs and 
larvae of Flies, with the object of preventing outbreaks of disease. His 
investigations proved to be of much value, and a summary of them 
will be published in the Journal. Later in the year he was urgently 
requested by the Secretary of State to proceed to India, in order to 
undertake another entomological investigation for the Government. 
The Council felt that the acceptance by Professor Lefroy of this 
appointment, entailing absence from England till January 1917 at 
least, rendered the holding of his Wisley appointment impossible, and 
his resignation was accordingly accepted, though with the greatest 
regret. 
10. Imperial College. — With the appointment of Professor 
Lefroy as Entomologist to the Society, relations were established 
between the Society and the Imperial College of Science. Although 
Professor Lefroy was compelled to relinquish his appointment in 
November these relations remain, and the prime object which they 
were designed to fulfil, namely, the establishment of a National 
Station for Research in Entomology at Wisley, will bejpursued.
