is intended to sustain the free end of the double hook (Fig. 1, 2 a). In 

 order to attach the rod in its turn to the small sides of the jar (Fig. Id), 

 a small glass strip (Fig. 6) having a semicircular hole (Fig. 6 d] is 

 pasted by silicate of sodium to the interior of either side and the two 

 ends of the rod are put in the holes (Fig. 1 d) . But we can also attach 

 the ends of the rod by placing them into small grooves which are cut 

 into the interior of the small sides and proceed vertically from the 

 upper edge of the jar (Fig. bd). Both the hook and the rod can be 

 improvised by the blowpipe. 



2) As to the arrangement of compact specimens a glass rod pro- 

 vided with a peculiar arrangement (Fig. 7, 8) is made to pass through

the object {f). The anterior end of the rod (d) possesses a small ver- 

 tical beam and the entire arrangement represents the figure of a Greek 

 T or of a crutch. This T-shaped rod must be placed into a square jar 

 of a corresponding size. The posterior end (e) is fixed to one of the 

 interior borders {be) of the vessel, while the anterior end or the verti- 

 cal beam mentioned resting on the opposite wall [a) is pasted to this 

 point. After fixing the T-shaped rod, the vessel is filled with alcohol. 



This rod can also be made by the blowpipe. 



3) Minute animals, such as polypes, small kinds of worms, etc. 

 kept in alcohol , can by this arrangement be brought into a most fa- 

 vorable representation in a collection destined for public instruction.
