 visibility. 3. Thin aqueous fluids. 4. Advantages of different media with 

 respect to granulation. 5. Thick aqueous media : advantages as to staining 

 and pressure. 



[Sec. II. requires considerable correction. Inter alia, the refractive index 

 of diatoms is put at "about 1'5," and balsam at 1-528, or a visibility of 

 • 028 ! Diatoms are stated to be more visible in air than in phosphorus. 

 The disadvantages of air-mounting are not referred to its inapplicability 

 for fine markings, but to a '' dulness or mist which gathers inside," &c.]

[Select a small tube about 1 in. in length, and fit it in a holder made of a 

 thin strip of copper, brass, or other metal having a hole bored tlirough it 

 to receive the tube. Let the mouth of the tube project slightly above the 

 metal, and support the latter in some convenient way over a sjjirit lamp. 

 Place a small quantity of white arsenic in the tube, and apply heat slowly 

 until a white powder begins to collect about the mouth. Then warm a 

 glass slip, and hold it over the top of the tube until bright crystalline par- 

 ticles appear on its under surface. Then remove the lamp and let the 

 tube cool.]
