If this is the species C. bulbifera it has not before been reported so far west as Arizona. Fort Moroni, near Flagstaff, Ariz., July 30, 1884. On the Sexuality of the BY H. MAESHALL WARD. I propose to show that it is probable that the sexuality of the higher Fungi has disappeared, because its purpose has been equally well or better attained otherwise than by means of sexual organs. Preliminary to this it will be necessary to be quite clear as to what sexual organs and the sexual process essentially are. The two points common to all the cases of sexual reproduc- tion which have been directly observed are the following: 1. A larger or smaller quantity of protoplasmic material passes from one portion (the male organ) of the same or another individual, into the protoplasm contained in another portion (the female organ). 2. The protoplasm contained in the female organ therefore becomes capable of further development; either at once, or, more generally, after undergoing a period of rest. It is not necessary to quote the numerous cases of observed analogies between the sexual reproduction of animals and plants; but will suffice to note that the essential in the sexual process is always the addition of a portion of protoplasm from the male, to the protoplasm of the female. But this is not all. It is now well established iu embryology that the normal ovum, or female mass of protoplasm, is incapable of further development until it has received the protoplasm of the male; that the latter, in fact, incites the former to further development. The outcome of all we know of these matters leads to the conviction that we have in the germination or development of an 1 The statement of the important hypothesis hereby
