RIBBON METHOD OF CUTTING 
SECTIONS. 
The Cambridge Scientific Instrument Company have designed a new and 
simple Microtome for cutting continuous Ribbons of Sections on the plan first 
adopted by Mr. Caldwell. 
original pattern of dispensing with the endless band altogether, and con- 
sequently not cnly avoiding the trouble of lifiing the series of Sections from 
the razor, butalso of ail wing them to fall on to the glass slide in their proper 
position furmounting. Although the instrument costs only cne-sixth the price 
of the original pattern, it will be found to doall that is required, and to 
possess the additional advantage of dispensing with the more complex and 
less important adjustments. Price of the Microtome, £5 5s. 
The Microtome may be seen at the Inventions Exhibition in Stand No. 
242, Group 28, in the South Central Gallery, as well as the Company's 
Cathetometer, Engineer's Level, Sine, and Tangent Galvanometer, Spectro- 
photometer, and other Instruments, descriptions of all of which will be sent 
on application.
