This fact would appear to be quite inconsistent with the theory above proposed, but it must be remembered that the ovum of Monotremes is known to remain for a short period in the oviduct, or in other words to pass through it very slowly, and to absorb fluid from its walls, as shown by the considerable increase in size which the ovarian ovum undergoes before it is laid. It would be interesting to know how long the rudimentary corpus luteum persists in _Ornithorhynchus_: the period, according to my views, should be very short. If this theory is sound, it would follow that corpora lutea are not formed in cases where the ova are not retained in the oviduct during their development. The essential process in the development of these structures is the hypertrophy and, in some cases at least, multiplication of the follicular cells in the ruptured follicle. I have already mentioned that this process does not occur in Teleosteans whose ovaries were studied by me. These were species of Teleosteans in which fertilisation is external. Marshall, in his _Physiology of Reproduction_, [Footnote: London, 1910, p. 151. ] quotes a number of authors who have published observations on the changes occurring in the ruptured follicle in the lower Vertebrata, and also in the Monotremes. According to Sandes, [Footnote: The Corpus Luteum of Dasyurus, _Proc. Lin. Soc. _, New South Wales, 1903. What was it rousd my soul to love? What made the simple brook so dear? It glided like the weary dove, And never brook seemd half so clear. Cool passd the current oer my feet, Its shelving brink for rest was made, But every charm was incomplete, For Barnham Water wants a shade. There, faint beneath the fervid sun, I gazd in ruminating mood; For who can see the current run And snatch no feast of mental food? Keep pure thy soul, it seemd to say, Keep that fair path by wisdom trod, That thou mayst hope to wind thy way To fame worth boasting, and to God. Long and delightful was the dream, A waking dream that Fancy yields, Till with regret I left the stream And plungd across the barren fields; To where of old rich abbeys smild In all the pomp of gothic taste, By fond tradition proudly styld, The mighty City in the East. Near, on a slope of burning sand, The shepherd boys had met to play, To hold the plains at their command, And mark the travllers leatless way.
