will allow, and then a concentration on special cultures suitable to the intellectual plane to which the pupil has been previously raised by the general cultivation.
Deeply religious in his innermost nature, he nevertheless fearlessly pushed scientific ideas to their legitimate conclusions. He believed that truth cannot conflict with itself; that true science is net antagonistic to a true religion, or vice versa; that pride and dogmatism on both sides are the only bar to cordial relations.

Although his life has been given to the development of original thought in various departments, yet Prof. Le Conte has not had the ambition to be a great book-maker. He, however, published a volume in 1873 on "Religion and Science," and has just issued a comprehensive college text-book of geology, the result of his twenty-five years' experience in teaching that subject.
