SUMMARY OF CURRENT RESEARCHES RELATING TO 



small animals his method is more satisfactory than vascular injection. 

 In the case of birds and small mammals so injected, he found that the 

 specimen passed into a state of mummification without any decomposi- 

 tion. Such mummified specimens are very suitable for the demonstration 

 of certain anatomical points. 



Glycerin Jelly Bath.*— This apparatus consists of a copper box. to 

 contain water, H x 2| x ;i in., on a separate iron stand, as figured 

 (fig. 75). There is a hole at one end to take the bottle of glycerin 

 jelly. In the centre there is a space with movable shelf, for slips and 

 covers. In use, the box is nearly filled with water, and the bottle of jelly, 

 slips, etc., put into position, and a spirit lamp or Bunsen burner placed 

 underneath. When the jelly is melted, the box is removed from the 

 stand and placed on the table (it is a convenient height for mounting 

 upon) ; a warmed slide or so may then be placed on the top of the box ;

the objects can easily be arranged in the liquefied jelly. The lid is re- 

 movable, and may be placed directly upon the iron stand when a greater 

 heat than that obtainable with the water-bath is required. The apparatus 

 is made by Flatters. and Garnett, Manchester. 



Microscope Slide Cabinets. f— The new style of cabinet recently 

 introduded by Flatters and Garnett is much more compact than the usual 

 type, e.g. a cabinet^ with glass door, to hold 720 slides only measuring 

 ing 18 x 10 x 10 in. They are made in several sizes, and in either 

 mahogany or pine. In the 720 size, there are five drawers, with brass 

 handles at front and space for contents card ; the two sides of each 

 drawer are cut away to allow of the removal of the slide trays, of which 

 each drawer holds twelve, each tray in turn holding twelve 3 x 1 in. 

 slides in separate divisions. Such an arrangement allows of immediate 

 access to any desired slide ; slides do not ride on top of one another, and 

 those relating to a particular subject may be kept in the same drawer 

 (fig. 7G).
