IT has been known from very early times that the liver-rot of various herbivorous mammals is a parasitic disease due to the presence of very numerous flukes in the liver of the affected animals. Amongst our domesticated animals the sheep is by far the most frequent victim. The fluke disease is always common in certain districts in England and in many parts of the world; but in consequence of a succession of wet seasons there was a serious outbreak of it in the winter 1879-1880, and it is estimated that in the United Kingdom 3,000,000 sheep were then destroyed by it. Hence special attention was called to the subject, and the research summarised in the following paper was undertaken on behalf of the Royal Agricultural Society of England.

For the sake of convenience the subject is divided into the following sections:—I. Historical, II. Methods of Investigation, III. Life-History.
