我的注意力首先被沃尔特·希普先生引导到生育问题上，我非常感激他。在农业出版物中已经描述了关于不同饲养方法和一般处理对羊毛或肉产量的影响的实验;但是，据我所知，除了希普先生关于1896年至1897年英格兰南部绵羊的“流产、不育和生育”的报告外，还没有系统的尝试来处理影响绵羊或其他动物生育力的因素。然而，每年都有许多实验是由羊群主人为了一个实际的目的而进行的，人们认为有必要将其中一些实验的结果记录下来，以便进行比较，并希望最终在这个问题上得出明确的结论。
My attention was first directed to the subject of fertility by Mr. Walter Heape, to whom I am much indebted. Experiments have been described in agricultural publications on the effects or different methods of feeding and general treatment upon wool or meat production; but excepting, so far as I am aware, for Mr. Heape's report on "Abortion, Barrenness, and Fertility" in sheep in the South of England for the year 1896 to 1897, no systematic attempt has been made to deal with the factors which influence fertility either in the sheep or in other animals. Numerous experiments, however, are annually conducted by flock-masters for a practical object, and it has been thought desirable to put the results of some of these on record with a view to making comparisons, and in the hope eventually of reaching definite conclusions upon this subject.
