Public domain books are our gateways to the past, representing a wealth of history, culture and knowledge that's often difficult to discover. oligacanthus, Sieb., from the gut of Calopleryx viigo, larva. In these cases the ordinary method of reproduction is by cell division, the spore formation appearing to be a special method that follows upon fertilization (Fig. e., after fertilization, and those that are formed asexually, for they differ both in structure and in function.

Marks, notations and other maiginalia present in the original volume will appear in this file - a reminder of this book's long journey from the publisher to a library and finally to you. The spores that are formed after fer- tilization are protected by firm and resisting coverings, and are able to live outside of the body of the animal in which they are definitive parasites; the other type of spores, formed asexually, have no such coverings and cannot live apart from the host.

Such secondary types are morphological evidences of changed metabolic conditions characteristic of the second period of vitality. — " Ohromid U." — \Vhile changes in the body form are often characteristic of the second period of vitality, there are great numbers of protozoa in which the external structure gives no clue to the state of affairs within.

Modern protozoology, therefore, has demanded as a basb for genera and species of protozoa a knowledge of the complete life cycle, and as a basis for classification not the struc- tures of the single cells, but the structures which the protoplasm may assume throughout its entire life history from fertilization to death or until the next fertilization. Nevertheless, in spite of the struc- tural modifications and special adaptations to particular modes of life, it is possible to group the different kinds of protozoa in four defi- nite types, first outlined by the French microscopist Felix Dujardin in 1841. In some cases these modifications are so highly evolved that we have litde reason to regard such cells as units of structure comparable with the tissue cells of higher animals and plants, but should look upon them as composed of still more elementary vital units, and to this extent the cell theory, when applied to them, is inadequate. They became much reduced in size, the endoplasm became distorted with vacuoles, and they died with absolutely no indication of disease through parasites.

Whether a book is in the public domain may vary country to country. Thus, in Tetramitus rostrat'us and Cercomonas loiifficavda a cyst is formed immediately after conjugation of two similar cells, and within the cyst the protoplasm fragments into hundreds of minute flagellated organbms. It is in the group of the sporozoa that we find the highest develop- ment of the spore-forming power, and here it has been found necessary to distingubh between the spores that are formed sexually, i.

After five or six days of ioeuba- tio D, the meroioitfls develop into sexually di Serentiated aameles: some are large and well stored with yolk material (d, e, f) ; others have nuclei which fragment into many s^i Uller par- liclea C'Chromidien"). The macrogameta is fertilised by one microgamete (0), and the copula immediately ■ecretes a fertiliutiou membrane which hardens into a cyst. We encourage the use of public domain materials for these purposes and may be able to help. each jranule beoomint the nucleus of a microgameie or male cell (d), h. The cleavaice nucleus divides twice, and each of the four daughter nuclei forms a sporoblaal out in aimless movement among the normally conjugating pairs. Such forms lend themselves to the culture method, and the success of Novyand Mac Neal and others with trypanosomes, herpetomonads, etc., in artificial liquid media follows from this nutritional characteristic. Sporonts solitary, massi\'e; spores biconical and thickened. omata, Lftger, from the gut of Hydrophilua Genus 47. IT Cilkins.)

Thus, in Onychodromua grandis the body of the cell becomes much reduced in size, loses cilia and cirri, while other organs both external and internal, atrophy, and the organisms die of senile exhaustion. Other forms of protozoa, as, for example, the parasitic amebte, may or jdov Go Ot^lc may not lend themselves to the culture method, and then only upon the condition of having other living things as food. Chromidia, in Hertwig's sense, is functionless extranuclear chromatin, but Schau- dinn and others have used the term to designate the sexual chromatin which is equivalent to the chromidialnetz in Hertwig's terminology. In Paramecium aurelia the circumstances accompanying old age have been described above, but in this case the metabolic processes had been restimulated, and apparently the cell organs were suitable for a continued activity, but something was wrong and the race died.
