 The Amphioxus model illustrates the features presented 

 by a side dissection of the whole body, and being on a 

 large scale can be easily followed by students. 



These models owing to their usefulness to students 

 are mounted in fiat wall cases at a convenient height 

 for every structure to be easily followed. 



The special wall cases have been increased by the 

 addition of one containing examples of Albinism. The 

 series of specimens includes cases of partial albinism in 

 the blackbird, goldfinch and robin, and complete albinism 

 in the case of the starling, swallow and guinea-pig.

Enquiries respecting insect pests have not been so
