Kate Maeion Hall, F.L.S., RZ.S., F.E.M.S. 



In the Proceedings of the Linnean Society of London (Oct. 1918) 

 appears an appreciative notice by Beatrice Harraden of the life 

 and work of Miss Hall, who was •'.lected Fellow of the Eoyal 

 Microscopical Society in 1910, She was for years the Curator of 

 the Stepney Borough Museum, one of the founders of the School 

 Nature Study Union, and was closely connected with the social 

 and educational work initiated by Toynbee Hall. 



Lord Avebury and many other eminent scientists were induced 

 by her to visit Whitechapel for the purpose of lecturing on popular 

 scientijfic subjects to the inhabitants of that district, whom she had 

 been able to interest in the wonders of Nature. 



One of her greatest pleasures was to conduct parties of boys to 

 the parks and woods and talk to them about the birds and flowers, 

 while the renown of her sea-anemone tank and observatory bee- 

 hive spread far and wide. 



Miss Hall was born in August, 1861, and died at Lingfield, 

 whither she had retired, on April 12, 1918.
