scientific institutions. His extreme modesty regarding the imporrance 
and value of his collections, and the patriotism shown in the disposition 
of the results of so great personal labor and care, are a moral object 
lesson to wealthy patrons of science. 
"The greatest and most enduring monument to Lacoe's devoticn to 
and work for science is the Lacoe collection. Carefully guarded against 
danger or deterioration, it will be increased in numbers from time to 
time by exchanges or additional gifts. Visitors to the paleontolcgical 
halls of the Nation's Museum may see an exhibit comprising a small 
portion of the more imperishable and attractive specimens of 'The La- 
coe Collections,' the greater number studied and identified by the fore- 
most paleontologists of the time. Its types, from the hands of Lesque- 
reux, Dawson, Scudder and Cope, will be consulted and re-examined by 
the savants of paleontology for centuries to come. Students of life dis- 
tribution, climate and of evolution will review its suites of specimens, 
and their records will supplement the records of the great paleontolo- 
gists of the past who have participated in its original elaboration. These 
records are in the paleontological literature of every land; and nhilc 
there shall remain a literature or a human interest in paleontology, the 
name and scientific service of R. D. Lacoe will be perpetuated. The 
•collection tells its own history; it tells of its author's intense interest 
and devotion, and of his great personal labors and aid in behalf of 
paleontology and geology ; by the notes and inscriptions, the patient 
and loving care in registration, the comments and remarks it tells of 
its relations to the students, of congenial scientific discussions, and of 
warm and lasting friendships between paleontologist and patron, welded 
•on the fossil anvil. The best, the most lasting scientific memorial of 
our friend and fellow is the great Lacoe collection."
