V 00 General Observations 



This chapter includes those formulas now the custom, greatly to the detriment 



which cannot reasonably be placed in any of the art, to use for mounting only those

and two subsidiary divisions. The for- cement the coverslip in position. The 



mulas in the first division (the cements, writer has elsewhere in the present work 



lutes, and varnishes— V 10) were at one expressed his opinion of the undesirability 



time of more interest to microtomists than of this custom, and it is to be hoped that 



is now generally the case. This indicates the inclusion of many of these older 



less a reduction in the value of the for- formulas for cements and varnishes, de- 



mulas than it does the changing fashion in signed to attach the coverslip to the slide 



the preparation of microscope slides. It is and to preserve within it a fluid medium,
