... them, Colonel Fergusson himself, Fleeming Jenkin, and Andrew Wilson, the Christian Buddhist and author of THE ABODE OF SNOW. Before these learned pundits, one member laid the following ingenious problem: "What would be the result of putting a pound of potassium in a pot of porter?" "I should think there would be a number of interesting bi-products," said a smatterer at my elbow; but for me the tale itself has a bi-product, and stands as a type of much that is most human. ...

Willgerodt suggested removing sulphuretted hydrogen by means of potassium hydroxide (caustic potash), then absorbing the phosphine in bromine water. For many reasons this process is only practicable in the laboratory. Berge and Reychler proposed extracting both sulphuretted hydrogen and phosphine ...
