 glasses and Microscopes, pp. 169-70, 176 (1 tig.). " Great magnifying 

 power may be obtained by a Microscope. Things appear 100 times, 200, 

 and even 1000 times larger than they really are." " Had we time, how 

 many astonishing and marvellous things might I not show with its help ! 

 Thousands of living beings in a drop of stagnant water, millions of tiny 

 red bjJies in a drop of bloud, and I cannot tell what besides."]

[Dissolve 1/4 oz. sulphate of copper and half its weiglit of liyposulphite of 

 soda in a little more than a pint of water. Well clean the diaphragm ; 

 place it in the solution and heat it. More hyposulphite will give a 

 darker tint ; more sulphate, a lighter steel-grey colour.]
