Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents The first cell-communities to be formed, which laid the early foundation of the higher multicellular body, must have consisted of homogeneous and simple amoeboid cells.

Disease and Its Causes Ova of various animals, executing amoeboid movements, highly magnified. The Evolution of Man — Volume 1 The oldest Amoebae lived isolated lives, and even the amoeboid cells that were formed by the segmentation of these unicellular organisms must have continued to live independently for a long time. The Evolution of Man — Volume 2 After a time they make their way into other red blood-corpuscles, develop into new malarial amoeboid parasites, and repeat the growth and sporulation. The Story of Germ Life Under certain conditions, examination has shown that they are protoplasmic and amoeboid, and that each one contains a central body of different staining properties from the remainder of the structure. Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 1 "Bisharin" to "Bohea" He was, we think, wrong in adhering to the belief that the movements of aggregated masses are of an amoeboid nature. More Letters of Charles Darwin — Volume 2 Their ova remain naked cells, which thrust out amoeboid projections, nourish themselves, and move about. The Evolution of Man — Volume 1 Our phylogenetic interpretation of the ovum, and the reduction of it to some ancient amoeboid ancestral form, supply the answer to the old problem: "Which was first, the egg or the chick?" The Evolution of Man — Volume 2 It is clear that this morula reproduces for us to-day the simple structure of the multicellular animal that succeeded the unicellular amoeboid form in the early Laurentian period. The Evolution of Man — Volume 2 We do not mean, of course, that the egg existed from the first as a bird's egg, but as an indifferent amoeboid cell of the simplest character. The Evolution of Man — Volume 2 This movement seems to be of no service, any more than the incessant movement of amoeboid bodies. More Letters of Charles Darwin — Volume 2 When they are not enclosed by a firm membrane, or confined in a "cellular prison," they can always accomplish these amoeboid movements.
