I'HVSICS AND CHEMISTRY. 43 



PRESSURE OF FLUIDS : HYDROSTATICS, PNEUMATICS, AND SPECIFIC GRAVITY 



(February and March). 



Pressure of Liquids. — Direction, transmission, relation between depth 

 and amount of pressure, specific gravity, buoyancy. Application to hy- 

 draulic presses and elevators, and to leveling instruments. 



Pressure of Gases. — Pressure of air. Comparison with pressure of 

 liquids. Application to explanation of air currents, winds, barometer, and 

 pumps. 



SIXTH YEAR. 



PROPERTIES OF MATTER — CAPILLARITY AND OSMOSIS 



(January). 



Properties of Matter. — Molecules and atoms. Porosity, compressi- 

 bility, elasticity, tenacity, hardness, ductility, malleability, and other prop- 

 erties. 



Capillarity and Osmosis. — Cohesion and adhesion. Experiments with 

 water and mercury with tubes of different diameters. Applications, em- 

 phasizing importance in plant and animal physiology.
