PREFACE.
Upon the death of Francis Maitland Balfour, a desire verynaturally arose among his friends and admirers to provide some memorial ofhim. And, at a public meeting held at Cambridge in October 1882, theVice-Chancellor presiding, and many distinguished men of science beingpresent, it was decided to establish a 'Balfour Fund' the proceeds of whichshould be applied: firstly to maintain a studentship, the holder of whichshould devote himself to original research in Biology, especially in AnimalMorphology, and secondly, 'by occasional grants of money, to further inother ways original research in the same subject'.

Thelast memoir in the volume, that on the Anatomy and Development of PeripatusCapensis, was published after his death, from his notes and drawings, withadditions by Prof. Moseley and Mr Adam Sedgwick, who prepared themanuscript for publication.

The fourth volume contains
