Service for Your Dog

A farmer named Muldoon lived alone in the Irish countryside except for a pet dog he for a long time.

The dog finally died and Muldoon went to the parish priest, saying "Father, the dog is dead. Could you possibly be saying a Mass for the poor creature?"

Father Patrick told the farmer "No, we can't have services for an animal in the church, but I'll tell you what, there's a new denomination down the road apiece, and no telling what they believe in, but maybe they'll do something for the animal."

Muldoon said "I'll go right now. By the way, do you think $50,000 is enough to donate for the service?"

Father Patrick replied "Why didn't you tell me the dog was Catholic."

Nicholas Joseph Callan

Born 22 Dec 1799; died 10 Jan 1864 at age 64.Irish physicist who pioneered in electrical science. Heinvented the induction coil (1836) before that of better-known Heinrich Ruhmkorff. Callan's coil was built using a horseshoe shaped iron bar wound with a secondary coil of thin insulated wire under a separate winding of thick insulated wire as the “primary”coil. Each time a battery's current through the “primary”coil was interrupted, a high voltage current was produced in the electrically separate “secondary”coil. By 1837, Callan used a clock mechanism to rock a wire in and out of a small cup of mercury to interrupt the circuit 20 times/sec on a giant induction machine, producing 15-inch sparks (estimated at 600,000 volts).«
