Excursion Secretary's Report. 



During the year there were eleven excursions, all of which were 

 successful, the average attendance being 17*3 against 17'6 in 

 the previous year. Though no especially remarkable captures 

 were recorded, the outings were much enjoyed by all, and it was 

 felt that the social relaxation they afforded was of particular 

 value to the members in these anxious times. Hearty thanks 

 are due to Mr. Offord, who after conducting the Ealing excursion 

 invited the members to his house, where they were kindly enter- 

 tained at tea by Mrs. Oftord. At the Richmond Park Excursion 

 Mr. and Mrs. Wilson undertook a similar kind office, giving the 

 excursionists a welcome and tea at their house at Kew. It is 

 necessary also to express our indebtedness to the Royal Botanic 

 Society and to Sir Phillip Sassoon for the permission to visit 

 their private enclosures. 



The Curator reports that during the past year the number 

 of slides borrowed has been well maintained, nearly 2,000 having 

 been lent. It has been a record year as regards additions 

 to the Cabinets, 448 slides having been added, 409 by presentation. 

 The principal of these have been over 100 very beautiful prepara- 

 tions of Diatomaceae and 60 various Botanical, from the collec- 

 tion of the late Mr. Dunstall. The sponge preparations placed at 

 the disposal of the Curator by the widow of the late Mr. Priest 

 have enabled the Club's collection of this group to be revised, and 

 many defective slides replaced, bringing up the total number to 

 165 preparations, many of great interest and beauty. Mr.
