[17] I adopt this division from an able American review of the “Vestiges.”
[18] For the details of this remarkable subject, see the “Parthenogenesis” of Professor Owen, p. 76, (London, 1849;) Steenstrup’s “Alternation of Generations,” published by the Ray Society in 1845, and Sedgwick’s “Discourse on the Studies of the University,” Supplement, p. 193, (London, 1850.)
[19] The subject of this lecture has been ably discussed, within a few years, in most of the leading periodicals in Europe and America, though I must say not always with the candor calculated to do the most good. The two most able volumes that have fallen into my hands, on the subject, are Professor Sedgwick’s “Discourse on the Studies of the University,” &c., (fifth ed., London, 1850,) and Hugh Miller’s “Footprints of the Creator,” now republished in this country.
[20] This subject has been treated more fully, and I hope more satisfactorily, in a little work of mine, which has just reached its second edition, entitled Religious Lectures on Peculiar Phenomena in the Four Seasons, (Amherst, 1851.) See the first Lecture, on the Resurrections of Spring.
