Excerpt from Species and Varieties, Their Origin by Mutation: Lectures Delivered at the University of California

Considerable care has been bestowed upon the indica tion of the lacunae in our knowledge of the subject and the methods by which they may be filled. Many inter esting observations bearing upon the little known parts of the subject may be made with limited facilities, either in the garden or upon the wild flora. Accuracy and per severance, and a warm love for Nature's children are here the chief requirements in such investigations.

In his admirable treatise on Evolution and Adaptation (new York, Macmillan Co., Thomas Hunt Mor gan has dealt in a critical manner with many of the speculations upon problems subsidiary to the theory of descent, in so convincing and complete a manner, that I think myself justified in neglecting these questions here. His book gives an accurate survey of them all, and is easily understood by the general reader.
