A correspondent writes: “D. LeRoy Topping died 
on July 20 in Honolulu, after a long illness. He was 
born in North Harpersfield, N. Y., on November 2, 
1861. Mr. Topping was interested in botanical field 
work, particularly in ferns, assembling large and im- 
portant collections not only from various parts of the 
United States, but also in the Philippines, where he 
served for many years; in Siberia, where he served 
with the American Red Cross following the World 
War; in British North Borneo, particularly on Mount 
Kinabalu, and in the Hawaiian Islands, where he has 
lived since his retirement in 1922.”
