High Precare Steam and Its False Promise in Engine Work
In mechanical engineering the past year has yielded few novelties and more wasted effort chasing high pressure steam as a fuel saver. Expansion gains depend on terminal pressure, not initial pressure, and practical limits around eight pounds per square inch curb expansion benefits. Isherwood showed expansion raises consumption, condenser effects hinder large expansion, and Watt’s condenser equals longer single cylinders rather than true separate condensation.

Fire Proof Suit Demonstrated in Vienna Parade
A Swedish inventor Deatherg unveiled a fire proof suit in Vienna before Emperor William. Captain Ahistrum wore the garment and walked into a wood and petroleum fire. The heat kept others eighty paces away while the captain moved about the flames undisturbed for fifteen minutes and emerged unharmed with no smell of fire on his clothes.

Sleeping on the right side aids digestion and prevents death
The piece argues that sleeping on the right side favors the stomach and prevents danger from a late meal, while left or back sleeping can hinder blood flow and cause nightmares or faintness. It warns that waking from a large late meal can cause severe illness or death and urges a lighter final meal and regular three meals daily. Hall's Journal.
