been cemented on may be removed by soaking, 

 the tile cleaned and used again. The arrange- 

 ment of invertebrate fossils mounted on these 

 tiles in almost vertical series enables the collec- 

 tion to be seen at a glance and to be read with 

 the facility of a printed page. 



Above all things it should be borne in mind 

 that no hard and fast rules can be laid down for 

 the display of specimens, but that methods must 

 be modified to suit the subject. The main ef- 

 fort of an exhibition series must be to attract, 

 interest and instruct the public and for this 

 purpose a small number of carefully chosen 

 specimens, well installed and well labelled is to 

 be preferred to a multiplicity of objects which 

 fatigue the eye and by their very number pro- 

 hibit careful examination. The student will 

 always search for information. One great aim of 

 a museum should be to impart knowledge to the 

 visitor who is not looking for it.
