and on the formation of a Lehigh alumni 
association at Philadelphia in 1870 he was 
chosen its first president, and a few years 
later was appointed an honorary alumni 
trustee. He last visited Lehigh on the oc- 
easion of a reunion of the alumni in 1897, 
when he delivered an address. He wasa 
frequent contributor to the collections of 
the several scientific departments of the 
University, and many of his collections are 
preserved in the University Museum. A 
nominal resident of, and frequent visitor to, 
Washington, he took a prominent part in the 
scientific activities of the Capital. He was 
one of the founders of the Anthropological 
Society of Washington, and of the Cosmos 
Club; he was also a member of the Wash- 
ington Academy of Sciences and of the 
National Geographic Society. 
Mr. Rock’s death was sudden, resulting 
from acute gastritis followed by heart fail- 
ure. The sad intelligence was reported to 
the State Department on the second of last 
February, by United States Consul-General 
McNally of Guatemala. 
In recognition of the great worth of the 
services which Mr. Rock had rendered to 
Guatemala during the years of his official 
activities there, the Government of that 
country took charge of the funeral, and he 
was buried in the cemetery of Guatemala 
City with public honors under the personal 
direction of President Cabrera. In their 
official reports to the Department of State, 
the representatives of this country in Gua- 
temala showed that Mr. Rock was univer- 
sally mourned, and that no such funeral 
honors had ever before been accorded to 
anyone but the highest officials of the coun- 
try. The most affecting if not the most 
impressive feature was the attendance of 
hundreds of poor natives, who had known 
Mr. Rock and experienced his never-failing 
kindness and generosity, who silently and 
tearfully followed him to his last resting 
place. Simple in their own lives and 
SCIENCE.

their command to the man whose singleness 
of purpose, love of justice and warmth of 
heart endeared him to all who knew him. 
Peace be to his ashes ! 
Mr. Rock leaves a widow, a married 
daughter, Mrs. F. L. Ransome, and a son, 
Alfred Mayer Rock, all of whom reside in

OTTO LUGGER. 
Orro LucGEr, State Entomologist of Min- 
nesota, who died May 21, from pneumonia, 
after a very short illness, was one of the 
most widely known of the many Americans 
of German birth who have obtained high 
scientific reputation in this country. He 
was born at Hagen, Westphalia, September 
16, 1844. His father was a professor of 
chemistry in a Prussian university. Lug- 
ger was educated in Hagen, and in 1864 
became a lieutenant of cavalry in the Prus- 
sian army. In 1865 he came with his pa- 
rents to the United States and secured a 
position with the engineer corps of the army, 
and for two years was engaged in the sur- 
vey of the Great Lakes. He had always 
been interested in entomology, and collected 
specimens while engaged in his engineering 
work. He became acquainted with the late 
C. V. Riley, who at that time was occupied 
in newspaper work in Chicago, and, when 
in 1868 Riley was appointed State Ento- 
mologist of Missouri, Lugger went with 
him as his assistant. During the years 
1868 to 1875, when Riley established his 
great reputation as economic entomologist 
and published eight of the nine annual re- 
ports which brought him lasting fame, Lug- 
ger remained his quiet, unassuming, self- 
sacrificing and devoted helper. In 1875 he 
married Lina Krokmann and went to Balti- 
more, where he became the curator of the
