BROWN, ON MICROSCOPICAL MANIPULATION. 



The microscopic stand and mounting apparatus has for its 

 object the direct and indirect application of heat; facilities 

 for mounting objects, and also of carrying lenses for dissection 

 a represents the stand or pediment, / being the receptacle 

 for the screwed end of the upright (b) and h a sunk portion 

 of brass, in which works the point (k) of the shank of e. 

 Upon the upright (b) is first slid the apparatus for indirect 



heat (c), and fixed at a convenient height by the milled screw 

 («). The shank (k) of (e) the "turn-table" is then passed 

 through the perforation of c at g and its point resting in 

 h of the pediment ; a rotatory motion may then be given it,
