mineral waters, and in hollows in the earth. He gave it the name of "gas sylvestre." He would doubtless have carried his discoveries much farther along if he had possessed the apparatus which is required for such researches. However, despite the lack of these facilities, he was able to describe hydrogen and marsh gas as special varieties which do not possess the same composition as ordinary air. Finally, in his treatise entitled "Pharmacopolium ac dispensatorium modernum" will be found a goodly number of useful instructions as to the proper manner of preparing drugs.

A complete collection of his writings was published at Amsterdam by his son, in 1648, under the title "Ortus medicinae vel opera et opuscula omnia."

He traveled all over Europe, going from one university to another and making the acquaintance of people who were well informed in matters relating to natural history, chemistry and metallurgy; and during all this time he appears to have absorbed a great deal of information relating to almost every department of human knowledge. Finally in 1526, soon
