This is the end of this Experiment (but not necessarily the game). All the cards are collected, shuffled, and the next experiment begins (now with one less Scientist). All unused DOCTORATES remain FACE DOWN with their respective Scientist.
The number of cards dealt is equal to the number of players left in the game. So, in a 6 player game with one player eliminated, there are now 5 players and 5 cards are dealt to each player. Play continues with the remaining Scientists each having 1 fewer box in their hand.
