MUSEUM METHODS. 

 THE EXHIBITION OF FOSSIL VERTEBRATES. 



The exhibition of fossil vertebrates is a 

 subject that may be treated ironi various 

 points of view, but the purpose of the 

 present paper is to deal with it from the 

 standpoint of a vertebrate zoologist, and to 

 discuss the question what should be the re- 

 lationship between the sections of a museum 

 devoted to the exhibition of living and 

 extinct animals. That there is, or should 

 be, a very obvious connection between these 

 two sections of a greatmuseum is undeniable, 

 although the relationship is generally ig- 

 nored and, as Prof. Flower wrote in regard 

 to the collections of the Royal College of 

 Surgeons : " The specimens continued to 

 be divided primarily, not according to their 

 zoological or anatomical relations, but by a 

 most inconvenient and artificial system, ac- 

 cording as the animals from which they 

 were derived lived before or after a particu- 

 lar period of the world's history."
