Scheutz Calculator- 1853
"The Swedish Calculating Machine ... Our readers will, of course, understand that the machine is not self-acting. It does not give logarithms, for example, merely for saying, Good machine, we want logarithms. It must be fed both with manual power and with calculation. The seed must be according with the harvest wanted; men do not grow figs or thistles, even in a calculating machine. But the return is greater than in most harvests; a very little calculation makes the machine do an enormous quantity of result by help of barrel-organ exercise. …The machine consists of more than 4000 separate pieces and weighs 10 cwt."
