 work of the Society ; it is with this conviction that I am induced to call your 

 attention to an agent hitherto little employed in the mounting of objects for the 

 Microscope. 



"It is a very desirable thing to have an agent by which an object

 cheap rate at most varnish makers and it dissolves readily in Benzole. The solution 

 forms a very sticky cement and can be used wherever gold size is usually em- 

 ployed, but with the advantage that it dries instantaneously. I find it very useful

 of the Gum Dammar cement on my slide with the turntable, then put the preser- 

 vative fluid in the ring with the object in, press down the covering glass, thug 

 squeezing out the superfluous fluid, the glass sticks firmly in spite of the 

 moisture, no air-bubbles run in, and after drying it off with blotting paper I run 

 a second ring round and put it away. Such slides I have had for upwards of two
