PREFACE
INTRODUCTION
CHAPTER I VARIATION UNDER DOMESTICATION
CAUSES OF VARIABILITY
EFFECTS OF HABIT AND OF THE USE OR DISUSE OF PARTS; CORRELATED VARIATION; INHERITANCE
CHARACTER OF DOMESTIC VARIETIES; DIFFICULTY OF DISTINGUISHING BETWEEN VARIETIES AND SPECIES; ORIGIN OF DOMESTIC VARIETIES FROM ONE OR MORE SPECIES
BREEDS OF THE DOMESTIC PIGEON, THEIR DIFFERENCES AND ORIGIN
PRINCIPLES OF SELECTION ANCIENTLY FOLLOWED AND THEIR EFFECTS
UNCONSCIOUS SELECTION
CIRCUMSTANCES FAVOURABLE TO MAN'S POWER OF SELECTION

INDIVIDUAL DIFFERENCES
DOUBTFUL SPECIES
WIDE-RANGING, MUCH DIFFUSED, AND COMMON SPECIES VARY MOST
SPECIES OF THE LARGER GENERA IN EACH COUNTRY VARY MORE FREQUENTLY THAN THE SPECIES OF THE SMALLER GENERA
MANY OF THE SPECIES INCLUDED WITHIN THE LARGER GENERA RESEMBLE VARIETIES IN BEING VERY CLOSELY BUT UNEQUALLY, RELATED TO EACH OTHER, AND IN HAVING RESTRICTED RANGES
