54,999. Sextuple Manometer after Kolbe, Figure, for demonstrating simultaneously the I B. d. 

 thermal conduction of six different solids, the temperature drop in a solid, the thermal 

 conduction in a liquid from top to bottom and vice versa; and electric conductivity, in 

 conjunction with the accessories listed under Nos. 55 000 55 009 and 54,975, which 

 should be ordered separately. The price does not include the receivers for heat experi- 

 ments, illustrated in the Figure, or the heating box (Kolbe - Skellon, Introduction to 



electricity, part 2, Fig. 127) ' 3. 17. 



A detailed description of the apparatus and the experiments which can be made with it is 

 contained in the Introduction Nr. 54,974 (sent free on application). The illustration numbers mentioned 

 in the accessories refer to this Introduction. 



55,000. 6 Receivers with Metal Rods and Heating Box, Fig. 54,999, for demonstrating the thermal conduction 

 of different metals (Fig. 28), with rods of copper, brass, zinc, tin, German Silver, and lead, coated 

 with thermo-paint j 1. 0.

in Liquids, Figure, arranged for heating the liquid columns from below and from above .... 1. 8. 



For heating from above one Sheet Iron Flask Xo. 54,986 b is necessary, this being excluded from 

 the price 0. 4. 6
