IN MEMORIAM 
13 
Doctor Bessey published much. Many of the papers em- 
bodied the results of searching investigation and reflection. 
The last paper was one on ‘‘The Phylogenetic Taxonomy of 
Flowering Plants/’ which was delivered at the Quarter Cen- 
tennial Celebration of the Missouri Botanical Garden. 
His reputation rested largely on his Text Book of Botany, 
published while Professor at Ames. This passed through sev- 
eral editions. Later only his Essentials of Botany was pub- 
lished. This was revised with the collaboration of his son 
Ernest Bessey as the “Essentials of College Botany.” This 
embodied his views of how botany should be taught, and he 
elaborated particularly parts dealing with the classification of 
plants. For many years he was one of the editors of The 
American Naturalist and of Science. In addition to various 
botanical notes he frequently reviewed important botanical 
papers. 
Doctor Bessey has left his impression on American botany 
by his writing and teaching and botanical science has lost one 
of its most sincere men, a friend and a great teacher. 
THE REVEREND DAVID MacMILLAN HOUGHTELIN. 
JOHN L. TILTON. 
David MacMillan Houghtelin was born at Gettysburg, Penn., 
January 14, 1872, and died at the Methodist Hospital, Des 
Moines, Iowa, June 3, 1913, aged 41 years. He was a gradu- 
ate of Baker University, Baldwin, Kansas, class of 1896, a 
graduate of Boston University School of Theology, class of 
1900, and a graduate student at the University of Glasgow, 
Scotland, in 1908. Most of the years since graduation were 
devoted to the work of the ministry, but from 1910 till the 
time of his death his life was devoted to the interests of the 
Methodist Hospital at Des Moines. While not engaged in scien- 
tific work his interest in science was such that he became an 
“associate” member of the Iowa Academy of Science in 1912, 
retaining his membership till the time of his death. In the 
death of Mr, Houghtelin the Acadamy has lost one of those 
many friends whose attitude of sympathy toward scientific 
work is greatly appreciated by the scientific workers of the 
state. ' : p]
