contained in the saying of the geologist, Sir Wm. Dawson, President of McGill University: “I know nothing about the origin of man, except what I am told in the Scripture—that God created him. I do not know anything more than that, and I do not know of anyone who does.” In view of this uncertainty and ignorance regarding the origin of the human body, it is extremely unethical to strive to impose the theory of man’s bestial origin by the sheer weight of scientific authority and prestige. Conscientious scientists would never venture to abuse in such a fashion the confidence which the people at large place in their assurances. Hence those who respect their honor and dignity as scientists should refrain from dogmatizing on the undemonstrated animal origin of man, however much they may personally fancy this theory. “We cannot teach,” says Virchow, “nor can we regard as one of the results of scientific research, the doctrine that man is descended from the ape or from any other animal.” (“The Liberty of Science,” p. 30, et seq.) And Professor Reinke of Kiel concludes: “The only statement consistent with her dignity, that Science can make, is to say that she knows nothing about the origin of man.” (_Der Türmer_, V, Oct., 1902, Part I, p. 13.) A slave, we are told (Tertul., _Apolog._ 33), rode in the triumphal chariot of the Roman conqueror, to whisper ever and anon in his ear: _Hominem memento te!_—“Remember that thou art a man!” It is unfortunate that no similar warning is sounded when the tone of scientific individuals or organizations threatens to become unduly imperious and intolerant. This tendency, however, to forget limitations and to usurp the prerogative of infallibility is sometimes rebuked by other reminders. The writer recalls an instance, which happened in connection with the Pan Pacific Conference at Honolulu during the August of 1920. The Conference was attended by illustrious scientists from every land bordering upon the Pacific. After the preliminary sessions, the delegates paid a visit to the famous volcano of Kilauea. Doctor T. A. Jaggar, Jr., vulcanologist and Director of the United States Observatory at Kilauea, acted as guide, the writer himself being one of the party. In the course of our tour of inspection, we came to the extinct volcano of Kenakakoe. There a number of volcanic bombs, some shattered and some intact, were pointed out to us. For the benefit of readers, who may not know, I may state that a volcanic bomb originates as a fragment of foreign material, _e.g._ a stone, which, falling into a volcano, becomes coated with an external shell of lava. In addition to the bombs, certain holes in the soil were shown to us, which Doctor Jaggar, evidently under the influence of military imagery suggested by the then recent European War, described as “shell-craters” dug by the aforesaid volcanic bombs.
