THE NAUTILUS. 143 



His collection embraces shells, crustaceans, echinoderms, corallines, 

 corals, fossil shells and plants, minerals, ferns, and marine algae. 

 There are six to eight thousand species of shells, and at a low estim- 

 ate twenty-five thousand specimens, from all parts of the world- 

 There are eight hundred species of marine algae, and four hundred 

 species of ferns. The latter include a nearly complete collection of 

 the ferns of North America, a complete collection from the Hawaiian 

 Islands ; also many from India, China, Japan, Australia, New Zea- 

 land, South America, Europe, etc. He stated that he had two 

 species not in any other collection. 



This vast and valuable collection he leaves without reserve to the 

 Illinois AVesleyan University, in Bloomington, where his life has 

 been spent, where his bride was wedded and laid to rest ; and here 

 his many friends will be permitted to again look through it, but 

 without his guiding hand and eloquent description. This gives the 

 Illinois Wesleyan University his life work, and endows it with one 

 of the finest conchological collections in the West. It will be 

 known as the " George W. and Rebecca S. Lichtenthaler Collection," 

 and will enshrine their names not only in the hearts of their friends, 

 but also in the hearts of many students who will receive inspiration 

 from his work, as many have done from his life.
