RIBBON SECTION CUTTING. 
The Cambridge Scientific Instrument Company have designed a new and 
simple Microtome for cutting continuous Ribbons of Sections of Microscopic 
Preparations on the plan first adopted by Mr. Caldwell. The new instru- 
ment has the advantage over the original pattern of dispensing with the 
endless band altogether, and consequently not only avoiding the trouble 
of lifting the series of Sections from the razor, but also of ailowing them to 
fall on to the glass slide in their proper position for mounting. Price of the 
Microtome, £5 5s- 
The Company are appointed Agents for the Microscopes of Zeiss, a supply 
of which is kept in stock.
