AN ACT OF CHARITY. “It is perhaps more foolhardy than courageous to assert that an almost universally used term is meaningless. Yet such an assertion I make here. I believe that a careful consideration of the term protoplasm will convince the unprejudiced judge that its various assigned meanings are so contradictory and have such uncertain reference to facts that to call the term meaningless is no more than an act of simple charity.”
