The King "was himself a fair chemist, and took a keen interest in the problems of navigation. The Duke of Buckingham varied his freaks of rhyming, drinking, and fiddling, by fits of devotion to his laboratory.

As Mr. Green says, "The curious glass toys called Prince Rupert's drops recall the scientific inquiries which amused the old age of the great cavalry-leader of the Civil War. Wits and fops crowded to the meetings of the new Society. Statesmen like Lord Somers felt honoured at being chosen its presidents. Its
