Lifework 167 



15 X 18 inches, of which we have about 5000. Many, 

 many insects, however, are still in various other types of 

 cork-bottomed boxes, since our trays are rather expensive 

 and we cannot buy them in sufficient numbers. 



In view of their fragile nature, and contrary to our prac- 

 tice with all other groups of animals, we are inclined to 

 mount our vertebrate fossils and put them on pubUc ex- 

 hibition. Our Chief Preparator, Mr. George Nelson, is 

 unexcelled in his abiHty to make graceful and lifelike 

 mountings and restore missing parts with perfect accuracy. 

 Of course there are many fossils where our material is 

 too incomplete to treat in this way. 



In all other groups, types are preserved for the use of 

 investigators and are not placed on exhibition. A recent 

 count shows that of reptiles and amphibians we have typical 

 material of 2173 named forms.
