Thirdly, and lastly, he appointed one of his brother professors to act as his sole executor, in disposing of those contents of his laboratory which were his own property at the time of his death.
"The written instructions to his executor are of such serious importance that I feel it my duty to copy them for you, word for word.
"Thus they begin:-- "'I hereby appoint my dear old friend and colleague, Professor Stein--now absent for a while at Munich, on University business--to act as my sole representative in the disposal of the contents of my laboratory, after my death.

The various objects used in my chemical investigations, which are my own private property, will be all found arranged on the long deal table that stands between the two windows.

They are to be offered for sale to my successor, in the first instance.

If he declines to purchase them, they can then be sent to Munich, to be sold separately by the manufacturer, as occasion may offer.

The furniture of the laboratory, both movable and stationary, belongs entirely to the University, excepting the contents of an iron safe built into the south wall of the room.
