The best collection of fossil horses, and one specially 

 arranged to illustrate the line of descent of the modern 

 horse, is to be found in the American Museum of Natu- 

 ral History, New York, but some good specimens, of par- 

 ticular interest because they were described by Professor 

 Marsh and studied by Huxley are in the Yale University 

 Museum. They are referred to in Huxley's " Amer- 

 ican Addresses ; Lectures on Evolution " " The 

 Horse,'''' by Sir W. H. Flower, discusses the horse in a 

 popular manner from various points of view and contains 

 numerous references to books and articles on the subject 

 from which anyone wishing for further information could 

 obtain it.
