May I repeat what I told you here: treat nature by the cylinder, the sphere, the cone, everything in perspective.

-Ce¤  zanne, Paul
  Letter to EŁ   mile Bernard,15  Apr.

   That vessel in which the powers of steam are to be employed to work the engine, which is called the Cylinder in common fire engines, and which I call the SteamVessel, must, during the whole time the engine is at work, be kept ashot asthesteamthat entersit; first, by enclosing it ina case of wood, oranyother materialsthat transmit heat slowly; secondly, by surrounding it with steam or other heated bodies; and thirdly, by suffering neither water noranyother substance colder thansteam to enter and touch it during that time.
