A support or peg for the Argand or bunsen burner when not 
in use (d). 
Retort and filter ring rod (e), this is attached to the foot (7) of 
the lamp by a bayonet joint not shown in the woodcut. 
An ordinary fish tail jet (/), on its peg, for glass bending or 
illumination. 
A. blowpipe jet (g) on its peg. 
A bunsen burner (A), provided with an air regulator at (7), and 
a gallery for the support of the draught shade or chimney (/). 
The foot (7) is made of lead instead of iron for the sake of 
increased stability and to prevent rusting ; it also is made to rest 
on three points for greater steadiness and to keep it out of liquids 
which may happen to be spilt on the bench, 
A more convenient position for the supply tap (A) is at the side 
at (J). 
There is also a rose burner, not shown in figure, to drop over 
the bunsen burner. 
All the parts are interchangeable and are provided with ground 
joints so as to avoid the inconvenience of their becoming fixed as 
often happens with screw joints. 
When the Argand or other jet is required for use, the bunsen 
burner is placed on the peg at the back, from which the former 
burner or jet has been removed, so that there is no need for any 
of the parts to get astray when not in use.
