CASES. 



iron frame and can be raised or lowered as circumstances de- 

 mand, by simply unhooking and placing in another hole. 

 These bracket irons should never be affixed to the wall of the 

 case but to a post inserted especially for the purpose. 



Upright cases are necessary for alcoholic specimens and 

 mounted mammals and birds ; all other forms, with a very few 

 exceptions are better displayed in horizontal or table cases. 

 In the construction of these the same care to make the cases 

 tight should be used as in 

 vertical cases, and the 

 same methods, with slight 

 modification, may be used. 

 The manner of applying 

 the rubber strip is shown 

 in fig. 24. It is best to 

 make the case deep 

 enough to accommodate 

 any specimen that may be 

 obtained, and then to have 

 a false bottom which by 

 blocking up will bring the 

 contents as near the glass as is desired. It is sometimes 

 convenient to have upright cases in connection with the 

 horizontal and at such times the form shown in fig. 25 

 possesses advantages. Horizontal cases may be clear un- 

 derneath, or they may be fitted with glass for the exhibition 

 of large specimens, or with drawers. Specimens placed in 

 such position cannot be seen to advantage ; while drawers 

 afford a large amount of storage room and hence in most 

 instances are preferable.
