The man who would coolly appropriate some discoveries of others under cloak of a mere prefatorial reference was perhaps an expounder rather than an innovator, and had, it is shrewdly suspected, not much of his own to offer. Meanwhile, it is tolerably certain that Ctesibius was the discoverer of the principle of the siphon, of the forcing-pump, and of a pneumatic organ.
The only difficulty to be encountered consists in the erection and working of machinery. There can be little fear on this score. We have no doubt that any London engine-maker would hit off the whole scheme of an air-cooling machine in half an hour. What is wanted is a forcing-pump wrought by a one horse or two bullock-power.
