Bottles having small necks are hard to fill without spilling the liquid. A funnel cannot be used in a small opening, and pouring with a graduate glass requires a steady hand. When you do not have a graduate at hand, a half egg-shell with a small hole pricked in the end will serve better than a funnel. Place the shell in an oven to brown the surface slightly and it will be less brittle and last much longer. - Contributed by Maurice Baudier, New Orleans, La.
“Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own.”
