The Royal Science Diagrams form an unusually complete series of illustrations for a course of elementary 

 lessons in Physics. They illustrate, by means of sectional and other drawings, many points which cannot be so 

 clearly shown by the use of the actual apparatus, and thus form an indispensable addition to the physical 

 laboratory. 



Sheet i. Pressure of Liquids. With coloured pictures, showing bladder on glass cylinder 



experiment ; Barker's mill ; hose ; and hydrostatic bellows. 

 Sheet 2. Thermometer. With coloured pictures of Centigrade thermometer ; method of 



finding freezing-point ; method of finding boiling-point ; and comparison of 



Fahrenheit, Centigrade, and Reamur scales. 

 Sheet 3. Air-Pump. With coloured pictures of air-pump and receiver with valves ; and 



syringe with valves. 

 Sheet 4. Barometer. With coloured pictures, showing the Torricelli experiment ; wheel 



barometer ; and Fortin's barometer. 

 Sheet 5. Common Pump. With coloured pictures, showing the suction valve shut and the 



suction valve open ; and bellows valve and butterfly valve. 

 Sheet 6. Force Pump. With coloured pictures, showing the suction valve open and the 



suction valve shut ; also spring valve. 

 Sheet 7. Pendulums. With coloured pictures, showing the simple pendulum, the compound 



pendulum, the mercury pendulum, and the gridiron pendulum. 

 Sheet 8. First Order of Levers. With coloured pictures of weight and fulcrum, balance 



steelyard, bellcrank, and scissors. 

 Sheet 9. Second Order of Levers. With coloured pictures of steelyard, nutcrackers, 



chipping-knife, and wheelbarrow. 

 Sheet 10. Third Order of Levers. With coloured pictures of steelyard, safety-valve for 



steam boilers, and clipping shears.
