The proposition that the cell is your maker or builder, that he is the cause of and builder of all plants and animals and that he is a conscious and intelligent being is a broad and sweeping statement. I do not think it has ever been made before in the history of the world. This proposition will no doubt be hotly contested by those institutions who may think that they will be financially affected by these facts becoming general knowledge. Someone said that "The greatest study of mankind is man." I would say, the greatest study of mankind is his maker, the Cell, This book will explain to the reader the cause of evolution, or growth, heredity and instinctive action in plants and animals. It will show that all plants and animals are built and produced by the microscopic beings we call cells. It will show that in their place in life they exercise the same intelligence in reference to their work as we do in ours and by reason of their intelligence, they are able to build a plant, a tree, an insect, animal or man, the same as we are able to build a house, automobile, ship or railroad. I propose to show by this book that although microscopic in size, the PREFACE cells are no less intelligent than we are. It will show that the cell knows how to multiply and organize his offspring into the vast co-operative colony we call plant or animal. Why should the builder and organizer of a large colony or army be less intelligent than the army? In other words, why should you be more intelligent than your maker? This book will explain the problems: 1st — Why will an acorn grow into an oak? 2nd — Why will it grow into an oak and not into a maple? 3rd — How can a bird, raised in captivity build a nest like its parent when it has never seen a nest before nor ever seen its parents? This book necessarily covers a wide field of knowledge from the fact that it attempts to show a conscious intel- lect in the cell similar to our own. In this inquiry it was necessary to investigate biology in all its branches, viz : embryology, heredity, psychology, physiology, anatomy, zoology, botany, and also chemistry and physics to a certain extent. The cell being the cause of all living structures, it was necessary to investigate his activities in all places. The plants and animals are cell colonies and are produced and maintained by them for their own selfish purpose. While I have tried to make the work as scientifically accurate as possible, I have also tried to avoid all technical words and phrases, so that the average man could understand it. While the opinions set forth in this book are based on my own investigations, I have also given extracts very liberally from others, so that the reader can better judge for himself on disputed points. I have introduced a large number of illustrations in order to make it clear, to sim- plify, and to save time for the reader. I have not over- looked the great difficulty with which I shall meet in PREFACE order to be able to get this book before the attention of the average man, as I shall probably be attacked by all institutions who may think they will be injured in their business. All colleges controlled, (and it seems that a large number of them are so more or less) will join with others in criticizing this book. No other branch of science has been so willfully obscured and mystified as the subject of life and especially the life of the cell. Even today if you try to discuss or explain the cause of a seed growing into a tree to the average so called educated man, he will only answer with an incredulous smile. He seems to know little or nothing of the life of the cell, which so vitally concerns the health and happiness of every person. I can only account for this condition of things by the willful suppression of the truth by the controlled institutions of learning. Such men as Chas. Darwin and Ernest Haeckel have done as much towards the advancement of human knowledge and progress as any two persons that have ever lived. Health is impossible without a clear understanding of life and without health, a happy life is impossible. For that reason I consider those two great students of life among the greatest benefactors of mankind. Dated, March 1915.

The purpose of this book is to clear up some of the mysteries of life, such as the cause of growth, evolution, heredity, instinctive, impulsive and reflex actions in man, animals, and plants. No one seems to understand or comprehend their real cause. Why and how does a certain seed grow into a weed or grass and not into a tree? Why do the young of animals, including man, look and act like their parents? Why does a kernel of corn develop into a corn stalk when placed in the ground and not into a sunflower? How can a bird raised in captivity, who has never seen its parents nor ever seen a nest of any kind, build a nest just like that of its par- ents? It knows how just as if it had been fully trained to do so, although it lias not had the slightest experience. People do not seem to know, and call it instinct. I have read everything that I can find on the subject and writers all seem to consider it a mystery. Now as it is no longer any mystery to me, I feel as though it might be my duty to write this book and give my opinion of it for whatever it is worth. 2 CELL INTELLIGENCE THE CAUSE OF EVOLUTION The textbooks of science have become very complex and technical and very numerous, so much so that a person in the ordinary busy life has not the time nor inclination to attempt to read up and study them so as to understand the great questions of life. The broad realm of science has been greatly extended in the 19th century. A great number of branches have been estab- lished by reason of research in different directions. This enormous expansion of the field of knowledge has led to a narrow specialism in many small sections. The exten- sive division of labor has prevented a comprehensive consideration of life as a whole. Each man has kept his mind on his little separate proposition and invented a lot of terms, words and phrases, which he has used in his little one sided work. This has caused a great deal of confusion and misunderstanding. One of the greatest scientists in Germany, Ernest Haeckel, states : "The vast structure of science tends more and more to become a tower of Babel in the labyrinthic passages of which few are at their ease and few any longer understand the lan- guage of other workers." This statement certainly is true and that is one of the main reasons why this book is written. There is no reason why a majority of the people should spend their lifetime upon this planet and know nothing or little about this interesting question of life and what it is. In this book I will try to explain my ideas in the very simplest language possible. The language used in almost all the text books is too technical and beyond the reach of ordinary readers. For instance — to give the reader an idea of what the subject of life includes, and what I have been reading, I shall outline a few subjects. First — This whole subject of life is called biology. This includes protistology or the science of single cells ; INTRODUCTORY 3 botany, the science of plants; zoology, the science of animals ; anthropology, the science of man ; morphology, the science of forms ; physiology, the science of functions ; anatomy, the science of structure; biogeny, the science of development; aecology, the physiology of work; his- tology, the science of tissues ; organology, the science of organs ; blastology, the science of persons ; and cytology, karmology, phylogeny, palaentology, geneology, trophon- omy, chorology, ontogeny, sensonomy, psychology, chemistry and physics. However, after reading these subjects, you have a lot of theories about metaphysics, mechanism, hylozoism, dynamism, idealism, materialism, hedonism, monism, dualism, vitalism, gases and fluids, statics, dynamics, acoustics, gravitation, electricity, and a great number of others too numerous to mention. Now it is clear that the busy man of today cannot afford to read up on all these subjects and theories, even if he understood the language used, as it would take up half of his life time to do so. After reading up on these sub- jects, I do not agree with any of them as to the cause of growth, evolution and development of life, heredity, in- stinctive and reflex action, and that is why I have written this book. After I have stated what my opinion and ideas are on these subjects, the reader must not stop and say to him- self,— ''Why, that proposition is ridiculous, I do not be- lieve it," but he must go on and read the whole book, as this is a big subject and no one can understand it so as to form an opinion without reading every chapter of this book. For thousands of years we thought the sun coursed around the earth; it was a bold theory to bring the sun to a standstill and set the earth in motion. We remember how poor Galileo had to suffer inprisonment for supporting this theory, which had been proven sev- 4 CELL INTELLIGENCE THE CAUSE OF EVOLUTION enty years previously by Copernicus. The astronomers were able to bring forward so many facts to support this theory that its truth was finally forced upon every think- ing person. The main fact I propose to prove by this book is that the cell is an intelligent being like ourselves. I have stated my proposition and it is now up to me to prove it. The proposition that the being we call cell is an intelli- gent being, includes also that he is so in every sense of the term, that he is conscious, has a memory, will and judgment, just as we have. He reasons and profits by experience, just as we do. By virtue of his power of memory and experience had in our bodies and thousands before ours, he knows how to build others like them. Before I go any further I must quote a few pages from a physiology now used in high schools and which most of you have studied, so as to fully remind you of what is known of this important individual we call cell; that is, that he is an independent living being; that he also lives a separate life, just as we do ; that he has the power of growth, self-repair and increase in numbers ; and that he requires food, air, water, and shelter, just as we do. Here is what our physiology has to say about the life of the cell : ''There are certain great differences between this unit of living matter and an unliving thing. Three distinguishing qualities belong to the living cell. (1) growth; (2) self repair; (3) increase in numbers through self division. These powers are possessed by no other material in the world save protoplasm. ''The growth of a cell is in all cases brought about by material taken in from the outside. In the human body this material is food, which after digestion passes into the blood, and is then taken in by the cells. This pro- cefs will be described more fully later. In some of the INTRODUCTORY 5 very lowest organisms where the whole animal is a single cell, solid particles may be taken into the cell through definite openings or "mouths." Jn others, the cell may change its shape so as to wrap itself about the particle to be taken in. But even in these instances, the particles must be dissolved or digested before they can be built up into the protoplasm of the cell. "At the beginning of its life, the animal consists of a single cell only, an Ggg, but as it grows the number of cells increase. When a child grows to manhood his increase in size is not due to growth of the individual cells making up his body but to the increase in their number. The cells of the adult are not larger than those of the child but more numerous. This multiplication is the result of repeated division of the original cell and in this process, every part of the cell divides Each of the resulting cells immediately commences to grow and continues until it becomes as large as the one from which it started, then it divides and the story is repeated. "We have thus seen that the body is made up of organs, that the organs are made of tissues and that the tissues are made of cells. Is it possible to carry this division further or is the cell the final unit? To this question we must reply that the cell is the final unit. It is true that the cell has parts, cell wall, nucleus, cell substances, etc., but no one of them can live by itself, while a com- plete cell may be an independent body and live an inde- pendent life. Although our own bodies are composed of many millions of these cells, there are some organisms made up of one cell only — these are microscopic and are called unicellular animals and plants. Although very tiny, each lives an independent life They vary in shape and diflfer in structure. Some of 6 CELL INTELLIGENCE THE CAUSE OF EVOLUTION them have ''mouths" ; others simply take their food in at any part of the body by allowing their protoplasm to flow^ around it. Some of them have organs for locomo- tion, others do not ; some have shells, while others have no covering at all. But each is a single cell and each carries out its own life process, such as respiration, secre- tion, multiplication, etc. The cell cannot be subdivided into smaller units which would be able to sustain inde- pendent life "Since such cells are the simplest parts into which living matter can be divided, we may call them "Units of Life" and may regard our bodies as a combination of a large number of such units, considering the life of the whole body as the sum of the lives of its different cells. We should constantly remember that it is really the cells which are the active living parts. The combined lives of all these millions of cells make the life of the whole, much as the combined lives of the persons within a city make up its life. "As we have seen, some animals are composed of a single cell. But this cell is able to carry on all the func- tions of life : it feeds, digests, respires, moves, multiplies and performs all the necessary duties of complete, in- dividual life. In our own bodies there are many cells, but each is not capable of carrying on all the functions of life and if separated from the others, would die. Each is able to do primarily only one thing, hence, each is de- pendent upon the others. "It may be asked, why we should have so many kinds of cells in our bodies and why with us too, one kind of cell could not serve all purposes. The answer is easy to give. A hermit can himself do everything needful to support his life : he can prepare his own food, make his own clothes and build his own shelter, but he can do this INTRODUCTORY 7 only because he lives very simply. When a family lives alone on the frontier, the members divide the work among themselves; the husband doing the work out doors, the wife that indoors, and the children contributing their different shares. When several million come to- gether, it will be found that some members of the com- munity are more skillful in building houses, others in making shoes, others in dressmaking, still others in cooking, etc., so the people agree to divide their tasks and share the results of their work. In this way they may have better houses, better shoes, better clothing and better food than before, because each man does what he can do best. As the community grows, this division of labor becomes extended until in a large city each person does only a very small part of the work necessary to sup- ply him with the things he needs. But he can do his own work well because he has only one thing to do. The life of a city is of much higher grade than that of a pioneer family. Its population has many more luxuries and accomplishes much more, all because of this division of labor. So it is among organisms. Where one cell does everything, the life is simple and on a very low scale. Each cell can feed itself and perform all the necessary functions, but the whole life is only one of growth and reproduction. As the cells become more abundant, they also become alike. Each takes upon itself certain duties ; each contributes to the good of the other cells and each receives aid from the others The life of any animal is the sum of the lives of its cells, and with many kinds of cells all working together for a common good, a higher grade of activity is produced than with each working for itself alone. Division of labor goes hand in hand with a rise in the scale of accomplishment and results in a superior type of life." 8 CELL INTELLIGENCE THE CAUSE OF EVOLUTION . Ernest Haeckel states, "Cells are grouped together under the idea of sculptors or builders because they alone in reality build the organisms." I go into details as to what the cell is, presuming that the reader has not any previous knowledge of what the cell is understood to be. I think it is necessary to do so in order to make a scientific subject like this interesting to the reader who may not know what the cell is. This you will see makes it clear that this animal or being we call cell is the agent who builds or makes the things we see in life, which we call plants and animals, including man. These wonderful beings are too small to be seen with our naked eye. They live separate and independent lives in both fresh and salt water. Such words as pro- tists, copepods, crustaceans, protoplasm, bacteria, germs, leucocytes, histons, somatic cells, germ cells and amoeba all mean the same, that is, they are cells. It is admitted by all that all living things, plants or animals, that we see are produced by these beings. The next question then is this : Do they do so by reason of their intelligence or do they do so by reason of some chemical force or otherwise? My proposition to be proven by this book is that they do so by reason of their intelligence in the same manner as we build a house or railroad. We are not prepared to say at this time just what intelligence is except that we know it exists. We know we are in- telligent and are guided by intelligence in our acts. These beings when they live separate lives in the water act precisely as other animals. They show, I believe, by their acts the same intelligence in their place in life as we do in ours. Looking at them through the microscope, Mr. Binet states : "If a drop of water containing Infusoria be placed under the microscope, organisms are seen swimming INTRODUCTORY 9 rapidly about and traversing the liquid medium in which they are, in every direction. Their movements are not simple ; the Infusoria guides itself while swimming about ; it avoids obstacles ; often it undertakes to force them aside ; its movements seem to be designed to effect an end, which in most instances is the search for food ; it approaches certain particles suspended in the liquid, it feels them with its cilia, it goes away and returns, all the AlTiocrion Spliete enclosing o ccntioiowft Nucleolus^ /f/^^°^^''^^ Nutleai M«nt.-l^^^3^WfTA4— Sponq«opla4»u Nucleus MeJfo^losr while describing a zig zag course similar to the paths of captive fish in the aquariums ; this latter comparison naturally occurs to the mind. In short, the act of locomo- tion as seen in detached Infusoria exhibits all the marks of voluntary movement." In this statement, Mr. Binet called them Infusoria. This animal has organs and acts precisely in the same manner as any other animal. It feels objects to decide whether they are good for food. It has a will, judgment and discretion, just as we have. It can decide for itself whether any particular substance is fit for food. It can* exercise discretion in the matter in the same way that we do in hunting for something to eat. The scientists of today do not consider the cell an intelligent being. They claim that he does not show anything but irritability. This word has caused much confusion and is practically meaningless as far as I can 10 CELL INTELLIGENCE THE CAUSE OF EVOLUTION •see. No one seems to know what is understood by this word. Mr. Binet seems to be also of the same opinion and states : "The term irritability, which though long in use has not in our opinion been happily chosen, since it is in the highest degree ambiguous and not suggestive of an exact signification." The little fresh water cell we call amoeba, who leads a separate independent life, is so very similar to those that build animals and man, that the microscope can discover no difference. Mr. Binet described his actions as fol- lows : ''The following is what occurs when the amoeba in its rampant course happens to meet a foreign body. In the first place, if the foreign particle is not a nutritive substance, if it be gravel for instance, the amoeba does not ingest it ; it thrusts it back with its pseudopodia. This little performance is very significant; for it proves, as we have already said, that this microscopic cellule in some manner or other knows how to choose and distin- guish alimentary substances from inert particles of sand. If the foreign substance can serve as nutriment, the amoeba engulfs it by a very simple process." You will see from this that his actions show discre- tion. In hunting for food he must exercise his judgment at all times as to where he is going and as to whether this or that is suitable for food. Such action of choosing must be based on former experience, which involves memory. Again here is what Mr. Binet has to say about the actions of cells, showing how they act when living as separate beings and not in those vast co-operative colonies we call plants and animals : "The Infusoria when in a medium abounding in food are almost entirely sedentary in their habits, only making slight changes of position. But if they are placed in a medium affording but little nutritive material, they become as migratory INTRODUCTORY H as the hunters and are seen to race about in all directions, searching for more abundant nutriment. It is hard to find a more perfect illustration of the influence exerted by the condition of a medium upon the habits and cus- toms of animals. The Patula is a type distinctively car- nivorous and possessed of an extremely voracious appe- tite, a fact which explains its power of multiplication, one of the greatest I have studied In constant pursuit of its prey, it seizes its victim by the two stout vibratile lips with which its mouth is armed and swallows them alive and whole. The victims may be seen strug- gling and tossing about for a time in the interior of its body and afterwards to expire slowly under the action of the digestive juices of the vacuole in which they have been inclosed." Notice in this how precisely similar the actions of these cells are to those of animals and human beings. They lie around and do nothing towards finding food as long as they have enough to eat, but lack of food and hunger stirs them to activity. The actions of these cells con- stantly in pursuit of their prey and the manner of eating and digesting their victims are certainly significant. They go to show that the animal or cell has the mind to know what he wants and goes after it. It is impossible to conceive of any living being moving towards an object for a purpose which has not a will and memory. It never can be shown to be a chemical or mechanical act. There must be in the mind of the being the feeling or idea of a need of food to spur him to action. Chemical force and other natural forces always act the same and follow fixed laws regardless of any condition or need. All scientists agree that matter can only act and change its place and form according to fixed laws. Living beings act accord- ing to their wants and needs. They are masters and are 12 CELL INTELLIGENCE THE CAUSE OF EVOLUTION able to direct the blind forces and crude matter to their own purpose and use. It may be said that even if it be proven that the cause of evolution, heredity and instinc- tive action is the result of the acts of the cell and that his acts are guided by intelligence, can you explain what intelligence is? That question may not be satisfactorily explained at this time ; however, we all can form a fairly good idea of what it is from our own experience. After we have fully proven that it is by reason of his intelli- gence that the cell is able from memory and experience to build the different structures we call animals and plants, then we can begin to push further investigations to discover, if possible, the deeper secrets of the inner life of the cell. It is a rule of science and philosophy that we should investigate a proposition as far as we can and when w^e can go no further to stop and admit it. No one will deny that there is such a force as electricity. We can see and feel its effects, but as yet no one is able to say just what it is although some very good theories have recently been advanced. It is the same with this property we call intelligence, that guides us in life. We know about what it is by the Way it guides our actions. It is enough to know for the purpose of this discussion, that it does exist. There are two main theories by which the growth and development of plants and animals in life are explained: First, chemical and mechanical forces ; second. Intelli- gence or a Divine Being. How^ever, so far no one has yet ventured the proposition or statement that the in- telligence that has caused the production of all these structures we see, such as plants and animals, was the property of the cell. Some call it God's will in the uni- verse or Divine Wisdom. Some call it intelligent force INTRODUCTORY 13 or vital force. They see a purpose and design in nature which seems to prove to them conclusively that it is guided by intelligence, and sometimes it is used to prove God's exisence in the universe or a Divine Will or the will of some other intelligent force in the universe. The other side attempts to explain the growth and develop- ment in life from chemical, mechanical and natural forces. Now whatever you wish to call it, no one can deny that whoever the being is who is able to effect the construc- tion of such stationary structures as trees and plants and movable objects as animals, must be possessed of a very high degree of intelligence. They are structures that present themselves to us with all the characteristics of a work of art. It stands practically admitted, that the cell is able to produce all these structures, partly of himself and partly from the crude elements of earth, air and water. We will see later when we get to it that he gathers the material with which he is able to effect these constructions in the same manner that we do. That in order to be able to manufacture the different materials that are needed to do this, he takes advantage of heat, light, electricity and chemical actions in exactly the same manner that we do except, of course, on a much smaller scale. You know that so far we have not been able to find anything in crude matter and the blind forces of nature indicating any intelligence. Nothing is found indicating any power to produce a work of art. It has now been conclusively shown that the cell is not a simple organism but a very highly organized animal or being, which is made up of still smaller beings. For convenience in the discussion of this question, we shall call this being the primordial cell. It begins to look as if these prim- ordial cells or beings of which the cell is composed are of that microscopic size that they may be able to handle 14 CELL INTELLIGENCE THE CAUSE OF EVOLUTION the molecules and atoms of matter and direct their actions and motions in the same manner as we are able to handle brick, stone, and larger particles of building material. We will see later that these primordial cells possess intelligence ; at least, their actions in the cell so indicate. You see, we are getting down to the question : Does intelligence exist in the atoms and molecules of mat- ter or is it a separate thing from matter existing in the universe? Is it invisible force separate from matter sim- ilar to the force of electricity or magnetism? These are questions to be settled by the scientists in the future. The only purpose of this book is to show that the cause of plants and animals, as we see them, is intelligence in the cell. He is the being who does the work of building and constructing all these living things, and he is able to do so by reason of the fact that he is an intelligent being like ourselves. We are quite conscious that there is a very great deal concerning which we know little or nothing. For instance — we have practically no idea of the nature of either gravitation or electricity. We realize that we have yet much to learn. We do know that such things as gravitation, intelligence and electricity exist. Memory is the power to receive impressions of things, — keep them for a long time and reproduce them when needed. We know this faculty of memory to be the base on which our intelligence rests. Without this power to remember and compare experiences, we could form no ideas or judgments. We would be unable to do anything based on past experience ; in fact, there cannot be any intellect or mind without memory. By reason of this power the cells can remember just how the structures were made from which they came, and how they acted while a part of such structures. The cells build the new structures, such as plants and animals, as like as they can INTRODUCTORY 15 remember, from their experiences in the structures from which they came, and also from their experience in build- ing similar structures in ages past. The instinctive emotional and reflex actions are gen- erally those produced and directed by cells in other places of the body and not in the brain. All these actions will be considered and explained in the chapter on heredity. You have probably been wondering what I would have to say about the theory of evolution being the cause of life. That theory does not exclude but goes to support my theory. Evolution is an undisputed fact. In a strug- gle for existence the fittest will survive, but the fact is only an incident in life. Survival of the fittest is a fact in nature, in business, politics, religion and among nations. In the struggle between two battleships, the best fitted for the struggle will generally win out. My contention is that the real cause of the existence of those individual struggling ships was the intelligence possessed by the builders. The ships did not come to exist by chance arrangement of matter. We shall find upon investigation that natural selection and survival of the fittest are the things that determine who shall live of two structures or individuals contending for space and existence. In the same manner, survival of the fittest is the thing which will determine who shall be the ruler of the sea, the English or the Germans, or whose factory shall survive in a town where only one can exist. The theory of evolution pro- pounded by Darwin and his followers does not account for the existence of the German and English navies nor for the existence of the factories, who struggle for existence, one against the other. My contention is this, that these factories and navies did not come to exist by chance. Some intelligent being has caused their construction or existence. Who are the 16 CELL INTELLIGENCE THE CAUSE OF EVOLUTION builders? Are they intelligent beings? We must ask the same questions in regard to the structures we see in life. We see a tree. It is a stationary habitation of a billion cells. We ask, who are the builders of that tree? It is admitted now that the cells are the builders of the trees they occupy. You ask, how can they build them? They do so by gathering the material and arranging it into the form of a tree. How could they do it? Because they are intelligent beings. The reader may not be famil- iar with Darwin's theory of evolution, so I shall briefly state what it is : First. All animals vary. Hardly ever are two born just alike. There is nearly always some point of differ- ence. Second. All animals and plants multiply so rapidly that all of them cannot possibly live. Third. All animals and plants are therefore in a con- stant struggle with each other for food and existence. Fourth. Those who have by chance been born with some feature that favors them in their struggle will live and perpetuate their kind. Fifth. This favorable variation will be passed on to the offspring through inheritance and in that way pre- served to that species. Sixth. By this process of continual variation, struggle for existence and inheritance, the different species of ani- mals have arisen. Darwin has also added sexual selec- tion. He shows that among many animals, there is a con- test in the breeding season among the males for the pos- session of the females. The contest is sometimes by actual combat and sometimes by an attempt to attract the favor of the female by the display of brilliant plumage or by singing. Now evidently those males who have espe- cially developed weapons for combat or especially beau- INTRODUCTORY 17 tiful plumage will be the victors, and will leave the most vigorous offspring, and the offspring will have the ten- dency to inherit the same weapons and plumage. This process developes antlers on the male deer and elk, and the beauty of the male birds. By means of this principle Darwin and other evolutionists have attempted to account for the evolution of life and the origin of new species from the old upon purely physical laws. We shall see that this theory is true only so far as it goes, and shall also soon see that upon analysis it does not go any further than I stated. That it is merely an incident and a fact that the best man or institution in the struggle for existence 'will win and live to perpetuate his kind or his institution or business. It does not explain who are the builders of these struggling institutions, structures or beings, nor how the builders are able to put them together. They do not attempt to explain or give any cause why one should inherit the features, form and character of his parents, nor why individuals should vary. In this book I shall attempt to definitely settle these ques- tions, so that Ave know where we are at, and can start in- vestigations of other and further questions. As Darwin's theory of evolution is based on inheritance, it must fail as a cause, as a great number of ants and bees have neu- trals, that is. they have males, females and workers. These workers can in no way pass on anything to their oft'spring, as they never have any. These matters w^ill be fully dis- cussed when we get to them. Spencer, like Darwin and others, attempt to show that life is based on chemical and mechanical action. They fail, however, to explain the mystery of growth, heredity and instinctive action. To show you how hard they have tried to understand it and how they have twisted the language to say something that would sound like a cause I shall here quote some passages 18 CELL INTELLIGENCE THE CAUSE OF EVOLUTION from Spencer, the great exponent of the Darwinian theory. He puts the question: "How can this cell con- struct a body?" Does every germ contain a model of the complete animal or is each germ a miniature form of same? No, all we can say is that the living particles com- posing one of these fragments have the innate tendency to arrange themselves into the shape of the organism to which they belong. He seems to see no other reason for the actions of the cell in building a plant except that they have "innate tendency" to do so. He would explain it just as well by frankly stating that he did not know. Fig. 2.— Amoeba highly magnified— Central portion, cell body, n. nucleus; c. v. bacuole; p. Pseudopodia, hands or arms extended. The question that will be discussed by me is not what intelligence and vital force are, but whether or not this intelligence that directs the cell is similar to and the same as that which directs intelligent man. Many scientists today are studying questions and theories which exist only in the imagination of the person who is studying them. We shall take, for instance, the subject of helio- tropism of living organisms. This word is used to denote INTRODUCTORY 19 the property in some plants or animals which compels them to go towards the light. I have examined this sub- ject and I am certain that no such property or thing ex- ists; that this high sounding word describes something that exists only in the imagination of some person. How- ever, the books are full of it and Jacques Loeb, M. D. PH. D and S. C. D. (member of the Rockefeller Institute) in his book on the Physico-Chomical or Mechanistic theory of life tries to show that this fact is the most significant proof that life is merely a chemical force. Here is what he has to say on the subject : "The positively heliotropic animals which go instinctively to a source of light have in their eyes photo sensitive substances, which undergo chemical alterations by light. The products formed in this process influence the contraction of the muscles mostly indirectly through the nervous system. In a series of experiments I have shown that the heliotropical reac- tions of animals are identical with the heliotropical actions of plants. In plants only the more refrangible rays from green to blue have the.se heliotropical effects, while the red and yellow rays are little or less effective, and the same is true for the heliotropical reaction of animals." Now here follow some of his experiments in the follow- ing words : **Some experiments on winged plant lice may serve as an introduction, etc. * * * In order to obtain the material, potted rose bushes infected with plant lice are brought into a room and placed in front of a closed window. If the plants are allowed to dry out, the aphides (plant lice), previously wingless, change into winged in- sects. After this metamorphosis the animals leave the plants, fly to the window and there creep upward on the glass." Then he makes the further remark: *Tt can be demonstrated in these animals that the direction of their progressive movements is just as unequivocally gov- 20 CELL INTELLIGENCE THE CAUSE OF EVOLUTION • erned by the source of light as the direction of the move- ments of the planets is determined by the force of grav- ity." Certainly Mr. Loeb must know that the cells who build these aphides or plant lice are in every way similar and identical to the cells that build him or Mr. Rockefeller. They are of exactly the same size and general appearance. I think the cells that build the plant lice show an extra- ordinary amount of skill and intelligence. As long as the rose bush was living, they were satisfied and contented because they had enough to both eat and drink. When Mr. Loeb dried up the rose bush and deprived them of food and drink, they had to get out of there and go some place where they could procure those things necessary to their life. They are compelled to do this just as Mr. Loeb would have to do under similar circumstances or starve to death. The plant lice could clearly see that there was nothing to eat and drink within any reasonable distance of where they were stranded. It looked to them like a "Long way to Tipperary." The only method by which they could save themselves from starvation was to pre- pare temporary wings and fly, which they did. Now where or in what direction should they fly? Anyone with sense would go straight to the place which would look like an opening in the prison or house in which they were enclosed. The light in the window would be the only thing that would direct them to a way to get out and find another green plant which is their only source of food and drink. What more could Mr. Loeb have done if he had been in their place? Endowed with the intelligence that Mr. Loeb and Mr. Rockefeller are now supposed to have, what more could they have done to save themselves from starvation? The intelligence, skill and knowledge pos- sessed by the builders of the plant lice to be able to build NTliOUrCTOilV 21 wings with which to carry themselves away, when neces- sary, in an emergency like that, is in my opinion won- derful. It is far superior to ours. Here is another illustration that Mr. Loeb gives of heliotropism : "If small crustaceans of a fresh water pond or lake are taken with a plankton net at noontime and •placed in an aquarium which is illuminated from one side only, it is found that those animals move about in the vessel pretty much at random and distribute themselves irregularly. Some seem to go more towards the source of light, others in the opposite direction, and the majority, perhaps, pay no attention, to the light. This condition changes instantly if we add to the water some acid. If the correct amount is added, all the individuals become actively positively heliotropic and move in as straight a line as the imperfection of the swimming movements per- mits towards the source of light and remain there closely crowded together on the illuminated side of the vessel. How does the acid produce this result? We will assume that it acts as a sensitizer." Mr. Loeb inquires, how does the acid produce this result and suggests that the acid probably is a sensitizer. We are forced to ask the ques- tion, that if a man were in the water in place of these ani- mals and someone should put enough acid into the water so as to burn his skin and body, if he would not become just as heliotropic as these crustaceans and if he would not make a scramble to get out precisely in the same manner. Being confined in a dark cave like the aquarium with acid burning his body, his only thought would be to ,escape from the place: The only thing to guide his ac- tions to effect an escape from this dark cave would be the light. It would be the only thing that could lead him or indicate to him an opening to the outside world. These cells or animals called crustaceans do nothing different 22 CELL INTELLIGENCE THE CAUSE OF EVOLUTION from what you or I would do under the same circum- stances. Then he makes the following comment: 'Tn certain animals, for instance in daphnia and in certain marine copepods, a decrease in temperature also increases the tendency to positive heliotropism. If the mere addi- tion of acid is not sufficient to make daphnia positively heliotropic, this may often be accomplished by simultan- eously reducing the temperature." In other words, he might as well say that if you cannot start them moving by burning them with acid you can do so by freezing or making it uncomfortably cold for them. Why should they not try to escape from a place where they are freez- ing or where their skin is being irritated and eaten by acid? I will quote you one more of his illustrations, which he thinks is very significant of the fact that some animals become at times possessed by a property that he calls heliotropism. I think it is the most absurd illustration of them all. Here is what he has to say about the young beetle, who comes out of the ground in the spring hungry and is very much in need of something to eat: "This change in the heliotropic sensitiveness produced by cer- tain metabolic products in the animal body is of great biological significance. I pointed out in former papers that it serves to save the lives of the above mentioned young larvae of chrysorrhoea. When the young larvae are awakened from their winter sleep by the sunshine of the Spring, they are positively heliotropic. Their positive heliotropism leaves them no freedom of movement but forces them to creep straight upward to the top of a tree or branch. Here they find the first buds. In this way their heliotropism guides them to their food. Should they now remain positively heliotropic they would be held fast on the ends of the twigs and would starve to death. INTRODUCTORY 23 but we have already mentioned that after having eaten, they once more lose their positive heliotropism, they can now creep downward until they reach a new leaf, the odor or tactile stimulus of which stops the progressive move- ments of the machine and sets their eating activity again in motion." I want the reader to stop a moment here and consider the absurdity of this statement. The actions described by Mr. Loeb of this beetle are those of any intelligent being under the same circumstances. When the beetle comes out of the ground, he is hungry ; he knows where to go to procure his food. Without having had any pre- vious training or information as to where to find some- thing to eat, he goes right after it. After having eaten one bud, he goes after the next one. This knowledge of where to go to find something to eat without having had any information on the subject, other scientists call in- stinct, but Mr. Loeb calls it heliotropism. He goes so far as to state that but for this heliotropism, the beetle would not know where to find his food and would starve to death. Why should the beetle lose his heliotropic prop- erty by eating a bud? Mr. Loeb states that this helio- tropism would pin him to the top of the tree, but for the fact that it is removed by the eating of the bud. Why should the actions of the beetle, any more than those of Mr. Loeb's, be those of heliotropism when going in search of food? You may ask, how can the young beetle know where to go without previous experience or information as to where to find his food? That will be fully and clearly explained under the chapter on heredity and instinctive action. The reader must remember that the cells who build the young beetle also direct its action and course, just as we direct the actions and course of a boat and other vehicles. The experience and knowledge are in the 24 CELL INTELLIGENCE THE CAUSE OF EVOLUTION cell, the builder of the beetle, who was but last year the director of the parent, and well remembers where it got its food. There are other tropisms beside heliotropism which are used to describe the property of organisms being attracted by light. There is geotropism to show that they are attracted by the gravity of the earth and galvano tropism to denote that they are affected by an electric current. These words are used in demonstrating that life is merely a chemical action affected by light, elec- tricity and gravity in the same manner as dead matter and chemical substances. So far as we can see and understand the question at this time, life seems to be an intelligent being we call cell, moulding and directing matter for its own use and pur- pose. I am not going to say just what life and intelligence in the cell really are. I only want to get matters lined up right in reference to those things we actually know. The cells in the brain of man are capable of directing his actions so as to effect the wonderful progress and inven- tions that have taken place. In building and maintaining the body, they act precisely in the same manner as we do. The cells which make up the lining of the stomach for instance, reach out their hands and select this and that from the mixed mass we have placed therein. They can always discriminate, for instance, between bits of fat and particles of coal, absorbing the former and leaving the latter. The surface cells pick out what is needed and hand it over to the other cells, who carry it to the place where it is wanted. Their acts show judgment and dis- cretion, the same as our own. There has been a vast number of experiments in late years and my opinion is based on these experiments and the conclusions that have been reached from them. Nearly all who are occupied in this work have been specializing. INTRODUCTORY 25 Each one in his particular subject has been so completely occupied with his part of the whole that he has not taken time to summarize or comprehend life as a whole. It makes me think about the story of the five blind men who went to see what the elephant was like. One put his hands on the elephant's side ; one put his arm around his leg; one got hold of his trunk; one took hold of his tail. As they were all blind and did not take time to feel of the whole animal, no one of them had any really correct idea of what the elephant w^as like. The one who got him by the leg thought he was like a tree, and the one who got him by the trunk thought he was like a snake, and the one that got him by the tail thought he was like a rope. It all depended on what place they had felt of him, and as their experiences were ail different they never agreed as to what the elephant was like and never could ; while a man who could see and had seen the whole elephant, could clearly hear from their discussion that they were all wrong. It appears to be similar with the scientists today. Each one feeling only of a certain spot is not com- petent to tell what life as a whole really is. There are certain things that we all can see, that the microscope has revealed to us as clearly and as certainly as the food we eat and the clothes we wear. That is to say, it is undisputed that these microscopic animals exist. We find them as living, single, separate, animals or beings in both salt and fresh water. Every drop of water taken from ocean or pond contains one or more of them. It is undisputed that these beings build from the material at hand all the structures we see and know as plants and animals. Upon this base of facts admitted, we can and should be able to agree as to the cause of development in life, inheritance and instinctive action. Beyond these facts, we do not yet know the inner life of the cell itself. 26 CKLL INTELLIGENCE THE CAUSE OF EVOLUTION We must stop now and then before the unknown. The more we become acquainted with this wonderful being we call cell, the more we see our ignorance of the depths of his real existence. Only a few years ago we knew very little about the life of the cell. Today we understand him a little better. Every day questions are put to the cell and some of the replies, though vague, reveal an unex- pected purpose and intelligence in his actions. I have stated enough to indicate the general purpose of this book and what I intend to prove by it, and shall now begin the argument by first considering what life really is as nearly as we can determine from all experiments made along that line up to the present time. CHAPTER II. WHAT IS LIFE? Life began sometime in the past history of the earth or else with the beginning of time. If it is a property of matter and came to exist far back in the Paleozoic ages when the world was young, conditions must have first become suitable for it to appear. It did not appear as a cell or bacterium but as one of those primordial cells or ultramicroscopic beings, which we now find organized into the perfect animal we call cell. This primordial being must have existed for ages as a single separate individual before it began its social life in the cell. It did not then understand how to transform solar energy into chemical energy and thereby make the food now used by us and the cells. This primordial cell without doubt exists today in a single state. There must exist at the present time a whole world of living creatures which have never been seen by the microscope, of all sizes from the single separ- ate primordial cell up to those cells we call bacteria, pro- tozoa and the plant and animal building cells. We can never find out what life really is until we can invent a method by which we can study and understand the inner Hfe of the primordial being which builds the cells. Up to the present time we can see that life exists only in this animal we call cell. A cell can come only from another 28 CELL INTELLIGENCE THE CAUSE OF EVOLUTION cell. In our question as to what life really is, we can only pursue our investigation by demonstrating what life is not. We can show, I believe, that life is not any of the forces of nature with which we are now acquainted, ex- cept the force that we call intelligence. Considering the fact that the cell is the builder of all things we see on this planet that have what we call life, or exhibit that phenomenon we can do nothing except to go into a de- tailed investigation of the actions of that individual as compared with the actions of matter. We have seen from our physiology that the cell is either a one cell organism living a single separate life for himself only, or a colony of millions or more cells living together and all working together for the good of the whole community, as we find the case to be in a plant or animal. For that reason they have been divided into unicellular and multicellular. In this discussion of what life really is, we can do no more than compare the actions of these microscopic animals with the actions of matter, as they are affected by the forces of nature, known to us as gravitation, electricity, chemical force or affinity, light, heat, cold, wind, water, etc. I think we shall find that these forces will, that is to say, they will affect the cell in the same manner that they would affect us if we were similarly situated. We shall try to see if pos'sible if the phenomenon of life is any one, some or all of these forces. We shall begin with the force known as light. Light is the waves of a medium which occupies all space in the universe and is known as ether. Light is known as ether waves. It has been demonstrated lately that these waves are different, just as are the waves of the sea, and according to their size they produce different effects. Some produce heat, some light, and some electric effects. Ether waves may be polarized, reflected, absorbed and refracted. We do WHAT IS LIFE? 29 not have any experimental proof as to just how these things take place, so we do not know, but there seems to be no doubt that light, radiant heat and electric waves are all of the same nature. The ether waves are some- times spoken of as visible or invisible light. The vibra- tion of the ether set in motion by the sun is heat when felt by the hand and light when felt by the eye. Heat is un- derstood to be and is a disturbance of the molecules of matter. The more violent the disturbance the more heat. The cells that build plants understand how to direct and use the heat of the sun. As the vibrations of the ether stir up the activity of the atoms of matter, the.cell knows how to pile them up in large molecules, which are called col- loids. These are merely building material and contain no life, such as proteids, fats, starches, sugar and other car- bohydrates. These building materials known as colloids are such combinations of atoms as break up very easily and when released can be again directed to take such form and substance as may be required by cells in any particular place in the body. As the atoms change from one substance into another, they jar the surrounding bodies and the atmosphere in which they come in contact, and this produces what we call heat. This atomic motion and vibration is also called chemical energy. Now as it is a fact that only a part of the cells understand or in other words have the power to make their own food and build- ing material from the raw material of earth and air by chemical action from the heat of the sun, it is clear that chemical action is not life nor the cause of life. Possibly heat is not very generally understood and the following is a good short description of heat by Garret P. Serviss: "Heat is a violent agitation of the infinitesimal particles or molecules of which all matter is composed, hence there can be no heat in a vacuum where there are 30 CELL INTELLIGENCE THE CAUSE OF EVOLUTION no particles of matter to be agitated or in the ether which is a medium that does not obey the ordinary laws of matter. But on the other hand the vibrations that give rise to heat when they encounter material bodies must exist in the ether because it is the ether which carries them, and since ether is not excluded like matter from what we call a vacuum, it follows that these vibrations may exist in the vacuum, in fact, the only thing that a vacuum con- tains is ether. No doubt these vibrations conveyed from the sun by the ether may produce many other effects un- perceived or unknown to us because we have no special nerves or organs of sensation suitable to their perception. The ether you will observe is a very mysterious thing and the discovery of its existence is one of the greatest tri- umphs of human intelligence. It seems to possess some of the properties of matter and yet it defies most of the laws of matter as we know them. To study all the phe- nomena of heat would require the devotion of an entire life time. Have you ever reflected upon the reason why heat can turn iron into a liquid and water into steam? Most persons seeing these things done or knowing they are done every day, think no more about it. It is not from among such persons that the great leaders of human ad- vancement make their appearance. But to return to the answer to our question — iron is melted and water is vapor- ized by that very shaking or agitation of their constituent particles of which we have been speaking. The mole- cules or particles of a solid or a liquid are held together by the mutual attraction, not the attraction of gravitation but another sort of attraction called cohesion. The dis- tance over which this kind of an attraction acts is very small. Rach particle draws upon its immediate surround- ing particles and they in turn upon others and thus the WHAT IS LIFEV 3I whole mass of a solid body or of a portion of liquid is held together. "In solids the force of cohesion is so great that the par- ticles are held in a rigid form. In liquids it is relatively so weak that the particles may slide about over one an- other, and in a gas or vapor there is no cohesion. Now when a solid is heated its particles are set into extraordin- ary vibration and if the heating is carried to a sufficient degree, the force of their cohesion will be so far weakened that they begin to slide over one another and the solid be- comes a liquid. If the heating is carried still further, the particles w^ill be so shaken that they lose their cohesive grip entirely, and the liquid expands into a vapor. "As you sit in front of your winter fire and see the black coal or hard wood molecularly shaken asunder in the jaws of heat until part of it ascends in gases and part falls in ashes while the agitation sets up new waves of heat in the surrounding air and ether, you may if you will, be- come a philosopher and contribute your own little share to the thinking which drives the world." This is a very good description of heat and particularly of the ether vibrations we receive from the sun. Mr. Serviss is of the same opinion as myself, that if we pos- sessed organs of sensation suitable to perceive, we would be able to understand very many other effects chemical and otherwise, which the waves of ether from the sun produce on matter. No doubt the cell is in possession of the different organs of sensation suitable to perceive the effects that the solar heat or ether waves have on matter and is thereby able to direct the atoms to afifect the large molecules in which he is able to store his building mate- rial and energy. It is a hard and tedious work to forge and mold the molecules of the raw material of earth, air and water into S2 CELL INTELLIGENCE THE CAUSE OF EVOLUTION food and building material, so a large number of cells have become parasites and live upon the work and energy of other cells. From this fact that some cells are able to use the heat from the sun's rays, to build and forge the material they require, and others not, it is clear that life is not caused by the heat of the sun but^that the heat is used in the same manner and for a purpose, as it is used by intelligent man. Coming back again to the question as to whether the light has a power to attract plants and animals, I believe it has, and that plants and animals act in the same manner as we do and for a purpose. They go towards the light for several reasons but mainly to get out of the place in which they are confined. Plant cells build their structures towards and into the light because they must use the rays of light or the waves of ether to effect the chemical action necessary to manufacture their food and the building- ma- terial with which they build those structures we call plants. In Mr. Loeb's book "On the Mechanistic Concep- tion of Life" he makes this statement : "At the present day nobody seriously questions the statement that the action of light upon organisms is primarily one of a chem- ical character." It appears perfectly clear to me that the organisms or cells are themselves not in the least afifected by the action of light any more than man except in this way, that if they are deprived of the sun's heat and light, they are deprived of a force with which they are able to manufacture those things that they must have to eat, and also those mate- rials with which they build their structures. Sunlight seems to contain a peculiar combination of energy con- taining both heat and electricity, which effect chemical changes in the raw material they gather from earth, air and water and produce those particular things they must WHAT IS LIFE? ^^ have for their existence. After Mr. Loeb has stated that light has certain effects upon the organism he makes the further statement : "While this chemical action is of the utmost importance for organisms the nutrition of which depends upon the action of chlorophyll, it becomes of less importance for organisms devoid of chlorophyll." The word chlorophyll is intended to mean a power in plant cells to make starch for food from the raw material of earth, air and water by the assistance of sunlight. You will notice from this statement that those cells who do not understand how to make starch by the aid of sunlight, are not attracted by sunlight in the manner that others are. Matter at the present time is classified into about 80 elements. These elements can be again broken up into molecules, molecules into atoms, and the atoms into elec- trons. All things in this world seem to be in motion. There is no real rest anywhere. It is always only appar- ent or relative. Heat and light themselves, which con- stantly change, are merely forms of motion. One writer states : 'Tn the eternal play of cosmic bodies, countless suns and planets rush hither and thither in infinite space. In every chemical composition and decomposition the atoms or smallest particles of matter are in motion and so are the molecules they compose." We will find later upon further investigation that some cells carry w^ith them a chemical laboratory where they are able to direct and forge the atoms into the larger mole- cules of matter to suit their needs. Charles G. Gibson in his "Scientific Ideas of Today." states : "We picture the elementary atoms grouping themselves into little congregations called molecules. We picture the atoms grabbing hold of one another and we find that the different atoms have different grabbing pow- 34 CELL INTELLIGENCE THE CAUSE OF EVOLUTION ers. For instance, when we combine hydrogen and oxy- gen together, each oxygen atom is able to grab two hydro- gen atoms to itself. Therefore, when we break up water into its constituent gases by means of an electric current, we find that we get twice the volume of hydrogen that we get of oxygen. The co-partnery agreement of the com- bination, known as 'water,' reads that there shall be two members of the hydrogen family, and one only of the oxy- gen family in the combination. "In our common table salt there is a very simple co- partnery, one atom of sodium combining with one atom of chlorine. Then again a single atom of gold will grab three atoms of chlorine to form the chloride of gold used in toning photographs. We see the elementary atoms with their electrical charges combining together and thus forming the neutral molecule, but even these molecules are far below the range of the most powerful microscope. We think of the invisible microbe again and try to realize that it contains millions upon millions of individual parti- cles or molecules, each of which contain several atoms. We therefore picture a piece of solid iron as being entirely composed of invisible atoms of iron. If we handle a piece of solid iron it is very apparent that the invisible particles of which it is composed must have a powerful grip on one another. To this force which binds the molecules to- gether, we have given the descriptive title of cohesion from the Latin word cohaereo, meaning I stick. *'Our thoughts naturally turn to the electrons, which along with the ether, are the most fundamental things of which we have any knowledge. It is evident that a very heavy burden falls upon those tiny charges of negative electricity. We have seen that they are the stuff that atoms are made of. Electric current and electric dis- charges are simply these tiny electrons in motion. We WHAT IS LIFE? 35 have also seen how the movements of electrons give rise to magnetic fields, electric waves, heat and visible light and every variety of ether waves. *'In the blazing sun we picture electrons revolving around myriads of atoms of matter at a great variety of speed. Why electrons go round some kinds of atoms faster than they do around others we shall see later. These electrons in the far distant sun are producing a great variety of different wave lengths in the ether. We see some atoms giving up one or more detachable elec- trons, which are accepted by other atoms producing a disturbance in their electric balance and causing the atoms to attract one another and become chemically united. In this way we account for the production of all the variety of all the compound substances known." This statement by Mr. Gibson will give the reader a general idea of how matter seems to behave to the mind of the scientific man today. It is sufficient to give the reader, who is not familiar with these things, some idea of the nature of matter, at least so far as will be neces- sary to a reasonable understanding for discussion of the question at hand. The reader will see that so far the modes of energy exhibited by force and matter in the uni- verse are not different from those in nature with which we have been heretofore familiar. The atoms and molecules of matter always follow fixed laws. We shall find that the actions of the cell are not those of fixed laws but con- trary to them. He is a master of matter. Does light affect the cells chemically or do they merely act as we would under similar circumstances?. Mr. Loeb gave the following illustration to prove that certain cells are chemically affected by light: ''When we observe a dense mass of copepods collected from a fresh water pond, we notice that some have a tendency to go to the light 36 CELL INTELLIGENCE THE CAUSE OF EVOLUTION while others go in opposite directions and many, if not the majority, are indifferent to light. It is an easy matter to make the negatively heliotropic or the indifferent (copepods) almost instantly positively heliotropic by add- ing a small but definite amount of carbon dioxide in the form of carbonated water to the water in which the ani- mals are contained. If the animals are contained in 50 C. C. of water, it suffices to add from 3 to 6 C. C. of carbon in water to make all the copepods energetically positively heliotropic. This heliotropism lasts about half an hour, probably until the carbon dioxide has again diffused into the air. Similar results may be obtained with any other acids." I would like to ask what any man would do under sim- ilar circumstances if he was in a room and someone filled it with a poisonous or irritating gas? Would he not also at once become ''energetically heliotropic" and attempt to escape from the room? Would he not also lose his heliotropism as soon as the noxious gases had passed out of the place where he was confined? I think he would in precisely the same manner as these cells, which are called copepods. The cell is an animal that feels, feeds and per- forms all the functions of life in every manner similar to that of Mr. Loeb. The advocates of the chemical theory of life base their strongest proof on this point of helio- tropism, which is entirely without foundation. I do not think it is necessary to go into any further detailed dis- cussion of the other tropisms like galvano-tropism and geo-tropism. The first is the idea that some cells are affected b)^ electricity, the other that they are affected by the force of gravity. While it may be said they are af- fected, still they are affected in no wise different from our- selves. They will take advantage of the electric force and turn it tp their own purpose similar to ourselves. For WHAT IS LIFEV 37 instance, the electric eel takes advantage of it and uses it in his business as a help in giving battle to his enemies, shocking and stinging them, thereby more easily captur- ing animals for food. In reference to gravity it affects them in the same man- ner as it does a human being. In order to be able to get up into the sunlight, the cell will defy the law of gravita- tion and build his structure straight upward. The cell is an individual that is in no manner and in no way forced and pushed around by physical and chemical forces re- gardless of any will or opinion he may have in the matter himself. The physical forces are not able to cause him to act in any different manner from what they cause man to act. There seem to be two sides only to the question, after looking over the enormous mass of philosophy and ideas written in the past in regard to the cause of life. One side claims that life came to exist sometime in the past history of the earth, out of the elements of the earth, and that it is only a chemical and mechanical phenomenon. The other side claims that a mind is back of matter, either separate from it or in the matter itself. Some call it vital force and some call it the Divine Will in the world or the universe. The plain reason for this difference of opinion arises from the fact that structures in nature show con- clusively that intelligence of a high order or at least sim- ilar to that of man is the cause that forms and molds the different structures of life. We shall not in this chapter stop to discuss what intelligence is, but will leave that to a separate chapter. It might be proper, however, at this time to give a short illustration of what is considered to be an intelligent act and one that is not intelligent and purely mechanical. I think the simplest illustration is the following given by 38 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Prof. Wm. James: "The pursuance of future ends and choice of means for their attainment are thus the mark and criterion of the presence of mentality in a phenomena. We will use this test to discriminate between an intelli- gent act and a mechanical performance. We impute no mentality to sticks or stones because they never seem to move for the sake of anything, but always when pushed and then indifferently with no sign of choice, so we call them senseless." Then Mr. Tames gives this illustration : "If some iron filings be sprinkled on a table and a magnet be brought near them, they will fly through the air for a certain dis- tance and stick to its surface. Let a card cover the poles of the magnet and the filings will press forever against its surface without its ever occurring to them to pass around its sides and thus come in contact with the object of their love. Blow bubbles through a tube into the bottom of a pail of water; they will rise to the surface and mingle with the air. Their actions may be poetically interpreted as due to a longing to recombine with the mother atmos- phere above the surface, but if you invert a jar over the pail they will rise and remain lodged beneath its bottom shut in from the outer air, although a slight deflection from their course at the outset or. a redescent towards the rim of the jar when they found their upward course im- peded would easily have set them free. If we now pass from such action as these to those of living things, we notice a striking difference. Romeo wants Juliet as the filings want the magnet but Romeo and Juliet, if a wall be built between them, do not remain idiotically pressing their faces against its opposite sides like the magnet and the filings with the card. Romeo goes over the wall or otherwise and touches Juliet's lips directly. With the filings the path is fixed. Whether it reaches the end de- WHAT IS LIFE? 39 pends on accident. With the lover, it is the end which is fixed. The path may be modified indefinitely. Suppose a living frog in the position in w^hich we place our bubbles of air, viz., at the bottom of a jar of water — the want of air will soon make him also long to join the mother atmos- phere, but if a jar of water be inverted over it he will not like the bubbles, perpetually press his nose against its un- yielding roof, but will restlessly explore the neighborhood until he has discovered a path around its brim to the goal of his desire." These illustrations are good and show clearly the differ- ence between an intelligent and a mechanical act. I do not believe it is possible to show any intelligence in a purely chemical and mechanical act, as it never acts with a purpose. The cell has been active for millions of years in building structures like plants and animals. In the petrified forests of Arizona we see that trees were con- structed in precisely the same shape and of the same size as they are today. We are satisfied that those trees were built by cells over two million years ago. After millions of years of practise and experience in building these sta- tionary habitations for themselves like trees and plants, and movable structures like animals, it is reasonable that they should show a very high degree of skill and intelli- gence in this line of business. By the aid of sunlight they are able to handle and direct matter, molecules, atoms and electrons with the same dexterity that our best builders handle brick, mortar and cement. The cells of our brain which do our thinking are not different from any of the cells of our body nor are they any different from the cells that live a single separate life in the water, nor from those cells that build plants. The slight difference in the general appearance of the cells of our body arises from the fact that they are occupied with 40 CELL INTELLIGENCE THE CAUSE OF EVOLUTION different kinds of work, just as a preacher looks different from a blacksmith,— but otherwise they are just alike in general construction. All the different kinds of cells such as muscle cells, blood cells and bone cells came originally from one single cell. From this fact, it seems to me that no reason can be given why one cell is not as intelligent as the other. Our intelligence is altogether based on our faculty of mem.ory. Without it we could keep no record of our ex- periences. Without experiences to refer to we could form no judgments. From the experiences stored up in our memory we form judgments and ideas which guide our actions. Based upon this faculty of memory, intelligence is possible and from it all intelligent acts proceed. This power of the cells in our brain to receive and store away information and experience we shall see later is not only a property of the brain cells but of all the cells of the body. Memory is a peculiar thing. In old age we remember the things of childhood the longest. Sickness weakens the memory. Repeating an experience strengthens it. Drugs, fevers and excitement bring back to memory things long ago forgotten. However, upon this power of memory possessed by the cells all intelligence is based. Upon this power, we shall see, inheritance, instinct and reflex action are based. Some go as far as to claim that matter acts as if pos- sessed of intelligence and a will. For instance, if we drop a crystal of salt in water, the salt will disappear, the atoms of salt will move around in the water in perfect freedom. If the water is evaporated the atoms of salt will again come together as if they possessed a will to do this. You will notice, however, that this is a will that follows a fixed law. We can say the same of a falling stone. It always tries to go back to the earth. We find the same WHAT IS LIFE? 41 thing in chemical attraction and affinity, and some have gone so far as to call this ''unconscious sensation,"^ what- ever may be understood by that expression. The word sensation is such a general term and subject to so many meanings, that it is hard to tell just what ideas they in- tend to convey. They have gone so far as to say that the actions of the atom in moving towards and joining other atoms to form other combinations of matter indicate a will and a soul in the atom. They claim that the actions of the atoms indicate a feeling of pleasure in getting to- gether, and one of displeasure in being separated from other atoms. It seems clear to me that all these actions, sensations or motions of matter that we have so far been able to discover show actions under a fixed law that we find everywhere in the universe ; while the intelligent action that we find in all organic beings we call alive, never moves under a fixed law, but always towards a fixed purpose regardless of those fixed laws of nature. I will admit that matter and force go together but some go further and claim that matter has both force and sensa- tion. That is true if you wish to call action sensation. How^ever, call it what you may, it is not intelligence. We cannot deny the great difference between a living and a non-living body. The past history of the earth shows that life has left a trail of failures and successes, pain, carnage and extinction behind, in its struggle for existence. One writer, Mr. Burrows, states : ''Man has taken his chances in the clash of blind matter and in the warfare of living forms. He has been the pet of no god ; the favorite of no power on earth or in heaven. He is one of the fruits of the great cosmic tree and is subject to the same hazards and failures as the fruits of all other trees. The frosts may nip him in the bud : the storms beat him down ; foes of earth or air prey upon him and 42 CELL INTELLIGENCE THE CAUSE OF EVOLUTION hostile influences from all sides impede or mar him. The very forces that uphold him and furnish him with armory of tools and power will destroy him the moment he is off his guard. He is like the trainer of wild beast? who, at his peril, for one instant relaxes his mastery over them. Gravity, electricity, fire, flood, hurricane will crush or consume him. If his hand is unsteady or his wits tardy, nature has dealt with him as with all other forms of life. She has shown him no favor." This is a very good description of the general condition that prevails in nature. This is a true description of the struggle for existence found everywhere in nature from the smallest bacteria to the largest cell, as well as among all plants and animals. We find the cell living singly in the ocean, in his separate struggle for existence, has made for himself a coat of armor from materials of different kinds, such as horn, lime and flint. Without sufficient intelligence to provide himself with these coverings, he would have been unable to battle with the crushing ele- ments of the sea and to perpetuate his existence. It might be interesting to the reader to know .what the great scientist, John Burroughs of the Rockefeller Institute, has to say in reference to what life really is. Here is part of an article written by Mr. Burroughs : "Our studies of the past histories of the globe reveal the fact that life appeared upon a cooling planet when the temperature was suitable and when its basic elements, water and carbon dioxide were at hand. How it began, whether through insensible changes in the activities of inert matter lasting whole geologic ages or through sud- den transformation at many points on the earth's surface, we can never know. "But science can see no reason for believing that its beginning was other than natural. It was inevitable from WHAT IS LIFE? 43 the constitution of matter itself. Moreover, since the law of evolution seems of universal application and affords the key to more great problems than any other generaliza- tion of the human mind, one would say on primordial grounds that life is an evolution ; that its genesis is to be sought in the inherent capacities and potentialities of matter itself. How else could it come? This is certainly the only natural road and it leads straight to the physico- chemical theory of the origin of life — the view held by an increasing number of biologists and bio-chemists of our day. It is the scientific view; no other view is possible to science as such. Science cannot go outside of matter and its laws for an explanation of any phenomena that appear in matter. It goes inside of matter instead and in its mysterious molecular attractions and repulsions in the whirl and dance of the atoms and electrons in their amazing potencies and activities, sees or seems to see the secret of the origin of life itself. "To the scientist the earth is complete m itself. He can admit of no break or discontinuity anywhere. Threads of relation, visible and invisible, chemical, mechanical, electric, magnetic, solar, stellar, lunar, geologic and bio- logic— forming an intricate web of subtle forces and influ- ences bind all things, living and dead, into cosmic unity. ''The disruptions and antagonisms which we fancy we see are only the result of our limited vision. Nature is not at war with itself. There is no room or need for mira- cles. There is no outside to the universe, because there are no bounds to matter or spirit. Science traces the chain of cause and effect everywhere and finds no break. It follows down animal life until it merges into vegetable, though it cannot put its finger or its microscope on the point where one ends and the other begins. It finds forms that partake of the characteristics of both. It is 44 CELL INTELLIGENCE THE CAUSE OP EVOLUTION reasonable to expect that the vegetable merges into the mineral by the same insensible degree, and that the one becomes the other without any real discontinuity. The change, if wc may call it such, probably takes place in the interior world of matter, among the primordial atoms where only the imagination can penetrate. "Looked at in its relation to the whole, life appears like a transient phenomenon of matter. I will not say accidental ; it seems inseparably bound up with cosmic processes, but I may say fugitive, superficial, circum- scribed. Life comes and goes; it penetrates but a little way into the earth ; it is confined to a certain range of tem- perature, beyond a certain degree of cold on the one hand it does not appear, and beyond a certain degree of heat on the other hand, it is cut off; without water or moisture it ceases, and without air it is not. It has evidently dis- appeared from the moon and probably from the inferior planets and it is doubtful if it has yet appeared on any of the superior planets, save Mars. Life comes to matter as the flowers come in the Spring when the time is ripe for it, and it disappears when the time is overripe. Man ap- pears in due course and has his little day upon the earth but that day must as surely come to an end. **Yet can we conceive of the end of physical order? The end of gravity? Or of cohesion? The air may dis- appear, the water may disappear, combustion may cease, but oxygen, hydrogen, nitrogen and carbon will continue somewhere." This statement is very interesting in that it shows how life looks to a man in a chemical laboratory, who can by reason of his peculiar occupation see life only as a chem- ical force and action. He has had hold of the elephant's tail. To him the elephant is like a rope. You will notice that at no place does he even mention or consider the cell, WHAT IS LIFE? 45 who is the builder of all living things we see. He can see only the atoms, molecules, electrons, smashing around in space like a great cyclone, tearing through a city, and in this clash and crash of the blind forces, life started and continues today. In my opinion a chemist from his lab- oratory can form no opinion of the structure and life of the cell. A chemist deals with the crude forces of nature, with dead matter. The remains of a watch, a threshing machine or a human being after it had been burned into a gaseous form would not furnish a person with any infor- mation as to the nature, character, purpose or inner life of those structures. The cell is an animal, very highly organized and specialized. Take the single cell called amoeba for in- stance. He has no machinery with which he can manu- facture starch. He does, however, carry with him build- ing material with which he can in an emergency save his life by covering himself with a coat of armor. Other cells carry with them a structure which is called chromato- phore. With this instrument, these cells are able to manu- facture starch from the crude substances of earth, air and water by the aid of sunlight. From these facts, it must appear evident to the reader that the cell is a very highly organized and specialized individual, and that to look at him from the point of view of being mere matter and force is the same as to compare the actions of a stone rolling down a hill with that of an automobile moving over a smooth pavement. One is compelled to move by reason of the force of gravitation while the other moves by virtue of the intellect that guides it. The structures of life, like plants and animals, are built from the materials taken from the earth, air, and water, just as are the structures man builds, like railroads and skyscrapers. If we were asked how it is possible for man to eflFect the construe- 46 CELL INTELLIGENCE THE CAUSE OF EVOLUTION tion of these railroads and buildings, we would say that it is by reason of the fact that he is an intelligent being. The intelligence of man is the intelligence possessed by the cells in his brain. If man is intelligent and by virtue thereof is able to combine and arrange matter and force so as to effect structures such as houses and rail- roads, why is not the cell also intelligent when he is able to direct the forces of nature so as to effect the structures we see such as plants and animals. The cell is not com- pelled to act by reason of any chemical and mechanical force, any more than is man. He acts by reason of a will and judgment of his own. He is a separate living animal. I see no reason to impute intelligence to the activities of atoms and molecules any more than to bricks and stones. Bergson in his "Creative Evolution" seems to see in mat- ter and life a creative energy. If we stood at a distance watching a skyscraper gradually grow into completeness, we would say there must be some creative energy back of it, pushing the construction and, if we could never get near enough to see the men and builders at work we could have no other idea of how that sky scraper came into ex- istence except that it was caused by some creative energy. How do we know that the cell does actually build all organic materials or living structure just as man builds his larger structures, like machines, houses, railroads, etc.? First — because we can now see him do it. Second — because matter itself is such that it never could and never will produce anything living. Is it pos- sible to demonstrate that all matter has this quality? I think it is. Wherever a tree is growing or sprouting, there the dead matter is being transformed into the liv- ing, but wherever a tree or animal is dead or decaying, it is gradually again turning into the organic matter. So it is with structures produced by man. While a house or WHAT IS LIFE? 4- city is occupied by the builders thereof, it is being main- tained or growing, so to speak, but as soon as the people are destroyed, the structures gradually return to the ordinary matter of the earth. We find the fossil remains of the structures of man, like old ruins of cities, just as we find fossil remains of the structures of the cell, like the bones of animals. Matter and force and chemical action act just the same in one place as in the other. They are the same and will act the same in your stomach as in the sun or any other place in the universe. We know that nourishment is transformed into the body tissues and through different channels it leaves the body in precisely the same quantity as it en- tered, partly unmodified and in other form. No atom of matter has been lost. Digestion is a chemical and me- chanical process. The cells are compelled to comply with and take advantage of chemical forces, matter and energy, in precisely the same manner that man does. The cells must keep up a continual chemical laboratory and mix and decompose substances according to the general laws of chemical affinity. They must be expert in their work and so it is with man, he can do nothing unless he is in- telligent and understands his work. The elements that make up the plant or animal are the same as those of a house or battleship. The cells of our body will handle the food furnished them in exactly the same manner as the raw material furnished to a factory. The coal, iron and other raw material are changed into the product in- tended or required. The plant building cells have produced the material for the cells of our body in the same manner that the miners have produced the raw material for our factories. In the factory as in the body, the laws of matter and force must be complied with. Water will penetrate, flow and 48 CELL INTELLIGENCE THE CAUSE OF EVOLUTION sink according to laws of gravity, in one place as well as in another. The knowledge of laws of matter and force in the universe is as necessary in changing crude material into the finished product in the factory as in our bodies. The laws of chemistry and mechanics must be observed by the people in the factory as well as by the cells in our body or in plants. The circulation of the blood is a purely mechanical act, like that of man pumping water. The cells that produce milk or digestive fluid must employ chemistry. The chemist will analyze the crude elements in a tree or animal and find that it contains the same ele- ments as are found everywhere in the universe, and from these facts he will draw the conclusion that life itself is only a chemical action. It seems to me absurd to make such a statement. If you should crush a skyscraper or battleship with all its inhabitants and analyze its mangled mass of iron, mortar, wood, brick, and human beings, you could not possibly find anything but the ordinary elements of matter found in the universe ; still it would be clearly absurd to say that the skyscraper or battleship had pro- duced itself from the raw materials, or that the iron, brick and mortar had produced the skyscraper, or that the wood, metals and other material had produced the battle- ship. There are several things now made by man that were produced a few years ago only by the cell. For in- stance, free nitrogen, dextrose, several organic acids, per- fumes, candles, Berlin blue, taurin, etc., were manufac- tured exclusively by the cells until recently, when man also discovered how to make them. Chemists are discovering how to make these products of life made by the cell, and no doubt in the future will be able to make many more, as we have plenty of the raw material from which to make them. We must, however, remember that chemical force and action is the same WHAT IS LIFE? 49 everywhere, and that the cell must plan, mix and guide the actions of the chemical forces and matter just as man does in order to obtain and produce these artificial com- pounds found in life. If intellect is not there to guide and direct the matter and force of the universe, nothing will be produced. Heat influences the actions of the atoms and molecules of matter. Even chemical attraction gives way to heat, so that all bodies at sufficient temperature are decomposed into free atoms or elementary parts. In this way heat performs a work in so far as it separates masses from each other, consequently a certain amount of mechanical work is equivalent to a certain quantity of heat and vice versa. In chemical action a transformation of energy of one kind into another takes place. The me- chanical energy of the atoms is converted into heat, which may again be used for the other forms of mechani- cal energy. This explains why heat is developed in a chemical process. Every chemical process can be called a combustion. In a violent disturbance of the atoms and molecules of matter, we have tfie common phenomena of fire and light. The fact is that heat is a source of stored or convertible energy. The only source of heat at the surface of the earth is the sun. The cell must obtain heat or energy somewhere with which to produce the atomic changes and molecular disturbances or chemical actions and changes desired. Without heat the cell could not produce the products required like fats, starches and sugars, any more than man could produce his works of art or products from the factory where chemical action or heat is required. The productions of the cell with which plants and animals are put together are products of, art. They are products that the forces of nature cannot produce. The irons and metals can never build an engine nor can the stones and brick produce a house. 50 CELL IMLLLIGENCE THE CAUSE OF EVOLUTION The blind forces of nature must be guided by an intel- lect towards a purpose. To build a machine the ore must be lifted from the mines, smelted into plates and bars. These again must be forged into the shapes and sizes to fit into every part of the machine. The cell will produce food and building material for future use in precisely the same manner as man will get the iron ore from the mines and melt it into plates for future use. The intellect of cell or man shows the same wisdom, foresight, and pur- pose. The laws of matter and motion, cause and effect which we have found are always the same in the universe, will prevent the ores from coming out of the mountain and building a steam engine. These same laws will also prevent the material forces from producing plants and animals. There must be a living being with an intellect to guide the matter and force towards a fixed purpose. The heat required to melt iron and metals is usually very high, so the cell does not use iron, brass, copper, etc., but such material as carbon, hydrogen, sulphur, phos- phorous, chlorin, potassium, sodium, magnesia, etc. By the aid of the heat obtained from the sun, the cell is able to mix and combine the atoms of these elements into such material as may be required for future use in building up and maintaining himself, plants or animals. The reduc- tion of carbonic acid and water into carbohydrates is done through the assistance and direction of the cells and from the sun they get their power and energy. Left to itself, we know that the sun could produce nothing. Products of art must be resorted to just as man takes advantage of photograph cameras and lenses or burning mirrors. It is very clear that the cell also must use similar artificial means with which to accomplish the results required. It seems clear that the cells have invented, constructed and possess artificial devices with which they can gather and WHAT IS LIFE? 51 direct the heat or energy of the sun and thereby mold mat- ter and direct the actions of the atoms of matter as they wish. At any rate we know that the sun may shine on carbonic acid and water until eternity without producing fats, carbohydrates and proteids. Without the intellect of the living being we call cell interfering, they would not be produced. The carbohydrates produced by the cells of plants are products of art and so are all the prod- ucts of cells. Knowing it to be a scientific fact that matter and force, gravity, chemical affinity, etc. will behave just the same everywhere in the universe, we know that the cell (whom we also know to be a living animal or being) must employ the same methods as man to effect his purpose and de- sires. Without intelligence man could not produce his products of art and it must be perfectly clear that the cell must employ the same means and be possessed of the same quality or power in order to be able to produce his products. Years ago before we had produced a microscope power- ful enough to see the cell, we could see particles of matter take their place and arrange themselves in order so as to become collectively plants or animals, whose parts bore a strict relation to the whole. From our knowledge of matter we knew that it could not act in that way towards a purpose unless it was guided by the intellect of some being similar to our own, no more so than brick and stone could take their place in the construction of a house with- out being guided by the. intellect of some living being. The thinker and observer could then as he can today, see that matter was guided by a mind similar to his own, towards a purpose. There seemed to be an invisible spirit in charge, directing atoms and particles of matter, which also proved to be the fact. 52 CELL INTELLIGENCE THE CAUSE OF EVOLUTION A being that is invisible is called a spirit. The cell is now no longer the spiritual being which he was a few years ago, but is a material living being. We can now see this being in charge and that he is the cause of matter growing into a plant or animal. He is the cause in the same manner as man is the cause of bricks and stones growing into a house. The designers and builders of plants and animals were to us spiritual beings because we could not see them. In the same way the designers and builders of skyscrapers and battleships would be spiritual beings to us if we could not get near enough to the struc- tures to see the builders. The builders of the cell are at this time passing from the spiritual condition into the mate- rial, because at this time we can just barely see them and not plainly enough to be able to say just what they are. We find the cell is no primitive organism. He is again a colony of primordial beings, which are, in fact, the real actors and workers. The cell is an animal that has evolved naturally from the smaller primordial beings in the same manner that plants and animals have come to exist by natural evolu- tion of the cell. It would seem that the cells who can make food and building material by the aid of heat from the sun, came into existence first. It is not likely that the heat from the sun was used by the cells until after the earth had cooled down to a certain temperature. It is likely that the heat used by the cells ages ago in the huge production of vegetable matter disclosed by the coal deposits was the heat from the earth and not the sun. It is generally understood that life cannot exist without sunlight, air, water and food, but it begins to appear now that life can exist almost indefinitely with- out any of these. The seeds from many plants, I know from my own knowledge, can live from five to fifteen WHAT IS LIFE? 53 years, and it is claimed that some can live a much longer time under conditions where they are not attacked by other cells or bacteria. This also goes to show that the cell must have fuel, air, heat and water when he is active producing living structures just as man must have when he is building and running factories, railroads, etc. The microscope disclosed to us a new world. If they had told us years ago that a drop of water contained hundreds of living animals that eat, drink, fight, love and reproduce, they would have had a hard time making us believe it. The school boy or anyone else today is compelled to admit that it is a fact, because through a microscope he can see it with his own eye. Now since a world of teeming animal life really ex- isted, which was not known to us because we did not have eyes suitable or powerful enough with which to see it, does it not seem plausible that there must still exist a world of still more microscopic proportions, which we shall probably see some day? When that time comes the builder of the cell will no more be a spiritual being, but probably a material living animal or being as the cell is today. It is easy to see what the materials are which the plant cells work up into building material for their habitation or colonies, which we call plants and animals. We also know that they use the heat and energy of the sun as a power. The atmosphere contains oxygen, nitrogen, carbonic acid and ammonia. The soil contains silica, iron, lime, potash, phosphorous, sulphur and ammoniacal salts. The soil and atmo:5phere contain all the material which is found in animals and plants and in the same manner we can point out the raw material contained in a railroad or battleship, but the cells, the builders, must separate, join and place the material in exactly the right place and in correct proportions to 54 CELL INTELLIGENCE THE CAUSE OF EVOLUTION effect the purpose desired. To do this it is just as neces- sary for the cell to be skilled and intelligent as it is for man. It has been repeatedly shown that the smallest cell, known as germ or bacterium, is constantly changing its habits and methods of life, and that any common, harmless species of germ may change its method of liv- ing and become a disease germ. Leahman and Neuman, the best authorities on this subject, state: "The division of bacteria into pathogenic and non-pathogenic, etc. as is still always done in textbooks, has failed absolutely. We can understand and know the pathogenic variety only if we study simultaneously the non-pathogenic from which the former have once originated and still always originate." They then go on and show that the different disease germs, such as typhoid, diphtheria, scarlet fever, etc., can be changed from one to the other by cultivation in different places and conditions. This is very significant to show how life in the microscopic world is a struggle for existence and how the cell in every place in life prepares and adapts itself to condi- tions. It is the same in the microscopic world as in our world, everything is in a state of evolution and change there, as well as elsewhere. Evolution itself shows that there is a struggle for a purpose. Evolution really proves intelligence because it means progress step by step. The cell will progress and build a tree or animal step by step in the same manner that man produces his structures. In order to cause matter to evolve in a certain direc- tion to produce a certain end or structure, and none other, the material must be directed and guided by in- telligence, as we do not find property or matter any- where with a tendency to develop towards any purpose. Desire and will of the cell must be back of matter to produce the organic or living things we see. Man, WHAT IS LIFE? 55 animals, plants and cells all show the same intellect in their places in life. How could it be otherwise when we consider the fact that man, animals and plants are also cells? If the products and industry of man arise from his desire and ideas, so must also the industry and prod- ucts of the cell. Insects will build a nest of clay and other material, lay their eggs in it and provide food for the young, which they will never see. Insects will do all these things without having had any previous instruc- tions. The philosopher and thinker would observe these marvelous actions and adaptations involving so many different ideas, and he would say, how is it possible for mere matter to pursue a purpose involving such com- plicated plans and combinations of ideas? He would say that the insect or matter of which it was composed was in charge of or guided by a Divine Will or invisible being or spirit. We find now that the thinker and ob- server was correct. The insect was, in fact, built by, was in the charge of and guided by an intelligent living being we call cell. They were to us at that time invisible, so they were correctly called Spiritual Beings. We see battleships and submarines move about on the surface of the water like ducks. They signal each other in like manner, and from all appearances and from their actions an observer and thinker would be compelled to say, looking at them from a distance, that they were directed and guided by spirits or some other intelligence. However, if he could use field glasses or the telescope or could get nearer, so as to be able to see the beings in charge of the boats, he would discover the beings or animals in charge of the battleships and these spirits would change into material living beings and the mystery would be solved. Every part of a body or plant reveals its use — for instance, the 56 CELL INTELLIGENCE THE CAUSE OF EVOLUTION « lungs reveal their use. It is the same in the battleship or other structure produced by man. Every part of ship or machine is made for a certain purpose. Oxygen of the air is necessary to produce heat and power in the battle- ship, so chimneys are provided to draw the air into the furnace. The gills are machines to separate the oxygen from water, and lungs to separate it from air. When we see the parts we know for what purpose they have been made. When we see a part of a battleship or railroad, we know what it is for unless we are very ignorant like the savage. In like manner when we see a part of a plant or animal we know what it is made for and that it is made by the cell. The intention and purpose reveals the same intellect in both cases. Just as man in possession of the same building material of metals, bricks, wood, etc. can con- struct buildings and machines very different from each other, so also can the cells with the material they possess in the elements, produce organs of plants and animals very different in external form and appearance. The savage or an ignorant man looking at a battleship or complicated machine, would have no comprehension how the ship or machine had come to exist or had been put together. So today, too, many people who have not studied life and the cause and composition of living structures, cannot form any conception of what a plant or animal really is. The brain of the bee contains only a few cells and is invisible except when viewed by the microscope. Still these cells in the brain of the bee, who direct all his actions, will manage a very effective battle against in- telligent man, as will appear from the following, from my daily paper: "Oakdale, Cal. — Forty school children were held pris- WHAT IS LIFE? 57 oners for half a day at Langworth school recently by a buzzing swarm of bees, which finally broke up the school for the day. "The bees had lived in one corner of the roof for weeks, and had been undisturbed until some of the youngsters threw clods and dislodged the hive. The bees attacked their tormentors, who took refuge in the school house. Miss Ida Warford, the teacher, put her head out of the door to see the cause of the commotion and was stung on the nose. Hundreds of bees swarmed into the half opened door and the children sought refuge in the next room while the teacher and the older boys did battle with the bees with wet cloths and whatever weapons they had handy. They, too, were finally forced into the other room, and the entire school was made pris- oner until some of the parents, alarmed at the absence of their children, came to the rescue. They were forced to flee, too, but finally came back armed with sulphur with which they routed the bees." What possible difference can there be in the intelligence evidenced by these people and the bees, fighting each other. The bees will behave and bother no one if left alone but in defence of their home and colony, they will fight to the last. In what manner do the actions of man differ from those of the bee? The cells that make the bee have had to fight animals for ages, and they are equipped with a poisoned dagger of a deadly character. Man was originally made not to fight but to escape from enemies through the trees from branch to branch. For that reason, he is a very helpless victim in a fight with other animals, but since his discovery of the club he has been king in the animal world, and has since been pro- gressing very rapidly. While he was fighting only a few years ago with clubs, spears, bows and arrows, etc., 58 CELL INTELLIGENCE THE CAUSE OF EVOLUTION he is now fighting with liquid fire. The bees first con- quered the teacher and the school children and then chased the farmers home. The farmers came back with reinforcements and fought the bees with fire and poison- ous gases. The bees fight with poisoned daggers and man fights with deadly gases. Both sides fight with poison in defence of their children. In what manner do they diflfer in their actions as intelligent beings? The cells building the bee must make the dagger and prepare the poison for a purpose, just as man does in his actions of foresight and preparedness. The cells in the head of the bee, as well as in man, are the parties who direct all the actions of this battle, and I fail to see any difference in their intellectual capacity. Not long ago we had no microscope enabling us to see the builders of a plant or animal. At that time we were compelled to say that they simply grew but now we have seen the builder, and the next question is, — how are those builders able to build these structures? In order to be able to discover the real cause, it will be necessary to first inquire into the inner life of these builders, how they live, eat and multiply, how and where they get their ideas and building material. That would be the only sensible way to find out how the sky scraper was con- structed. We have penetrated far enough into the mys- teries of matter, molecule, atom, and electron. We can at this time clearly see that matter and force in the uni- verse is everywhere the same ; they always follow fixed laws and cannot be destroyed. The form and nature of the energy can be changed from one to the other; for instance, in the dynamo we see mechanical energy trans- formed into electrical energy, which in turn may be transformed into heat energy in the electric furnace; or the electric energy may be transmitted to a distance and WHAT IS LIFE? 59 be converted once more into mechanical motion by means of the electric motor. The kinetic energy of a waterfall may be transformed into mechanical energy by means of the old-fashioned mill wheel, and we might go on in this manner considering one series of transformations after another. The force of a living being is different from these natural forces in this, that it directs and guides the natural forces to its own purposes. Not many years ago we did not know that cells pro- duced the trees, plants and animals we see, — we did not know" that those builders existed. When I first became interested in nature and biology, we were told by the scientists that the cause of plant growth was endosmosis and crystallization. We know now that the plants and ani- mals that we see are structures produced by smaller animals we call cells. By reason of a more powerful eye made partly 'by ourselves and partly by the cell, we can see these individuals. The cell makes our eyes as nearly suitable for every day use as he thinks best, but for a further special use like seeing smaller things like cells, or for distant objects like planets, we add to or change the arrangement of the lenses of the eye to effect the purpose desired. It requires just as much intelligence to build the eye in the first place as to change it for any special or particular purpose afterwards. The cell is not a mass of matter composed of electrons, atoms or mole- cules, but is a highly organized and specialized living being. We shall find that he is made up of possibly millions of still smaller living beings. It seems clear that the only method to solve the. mystery of life is to more completely investigate the inner life of the cell and put all the questions to him. It seems to me the only reason that so many ideas and diflFerences of opinion about life have arisen is the fact 60 CELL INTELLIGENCE THE CAUSE OF EVOLUTION that we have not been able to look upon -he cell as the primary source of life and intelligence. The mechanical side could see nothing but matter and force, the other side could see nothing but mind and intelligence back of it. The fact seems to be clear, that the same mind and intelligence is back of the production of plants and ani- mals, in the same way and to the same extent that mind and intelligence is back of all those structures produced by man. In either case the mind and intelligence is and must be in the actual builder of these structures. We know that it is not matter that is building plants and animals. It is the microscopic wonder we call the cell. We must remember that life came into existence millions of years ago and how it started we can only guess. It has had time to develop in so many millions of ways that we cannot hope to comprehend just how it came to be in the condition that we now find it. We all have a right to guess on that subject. We know that life is not heat because it can exist in a frozen condition for a long time; the seeds of wild plants live in the frozen north for years. Some experiments of late go to show that fish can be frozen for months in solid ice and live when thawed out, as will be seen from the following clipping from a Scientific Journal : "The feat of freezing live fish and reviving them several weeks or months later has been achieved by the Swiss scientist, M. Pictet. The scientist put twenty-eight live fish in a box that contained water rich in oxygen, in which several pieces of ice floated. The temperature of the water was then reduced slowly until it froze. At the end of about two months the cake was gradually thawed and the fish, it is said, were found alive. In such an experiment, the scientist reports, it is essential that the water be gradually frozen and that it shall have contained pieces of ice for from WHAT IS LIFE? 61 fifteen to eighteen hours before the whole mass is frozen. The process of thawing must also be slow. "Through this process it is believed that Siberian stur- geon and Alaskan salmon can be exported alive to dis- tant markets." It is clear that life is not sunlight nor has sunlight pro- duced life because the lower organisms or cells such as bacteria are disorganized and destroyed by sunlight. We also know that life is not electricity or magnetism because we see this force employed only by some animals and not by others as in the great electric eel of Africa where the electric organs weigh more than one-third of the entire fish. Life is not any of the forces of nature that we have yet discovered. The cell is the animal that contains life. We contain life because we contain the cells, in the same manner as a ship contains life because it contains people. The cell builds with the crude elements of matter and force in the universe in the same manner as man does. In answer then to the question, what is life, — we are compelled to say that it is the activities and products of the living animal or being we call cell. CHAPTER III. THE CELL. We shall now investigate the inner life of the cell as far as we can go with the evidence at hand up to the present time. I shall try not to deal with the speculative side of the subject any more than will be necessary to show up some of the problems yet to be solved. Some of the theories will be referred to in order to show where we are at, and which will point to further investigation of the facts. This chapter will attempt to discuss the actions of the cell in reference to his inner life, his methods, appearance and actions. No distinction will be made between animal building cells, single cells and plant building cells, as there is no difference in their primary method of living and reproduction. The reader must understand that in this short chapter no complete history or description of cell life can be attempted. All I can do is to briefly outline those facts about the cell that now seem to be admitted, so that the reader can see for himself what kind of an animal or being the cell appears to be. We shall consider the cell mainly under two heads: First — Its general appearance, structure and organs. Second — How they multiply and increase in numbers. In my investigation of books discussing the life of the cell, I found Edmund B. Wilson, professor of zoology of THE CELL 63 Columbia University, New York, about the best writer on this subject and shall quote him more than anyone else, to show the reader what we know about the cell at this time. I think he is very careful in his statements, and does not state any propositions as true unless ad- mitted and backed up by very good authority. The fol- lowing is a part of his introduction to the study of the life of the cell : "Among the lowest forms at the base of the series are an immense number of microscopic plants and animals, familiar examples of which are the bacteria, diatoms, rhizopods and Infusoria, in which the entire body con- sists of a single cell, of the same general type as those which in the higher multicellular forms are associated to form one organic whole. Structurally, therefore, the multicellular body is in a certain sense comparable with a colony or aggregation of the lower one celled forms. This comparison is not less suggestive to the physiologist than to the morphologist. In the one celled forms all of the vital functions are performed by a single cell. In the multicellular forms, on the other hand, these functions are not equally performed by all the cells, but in varying degree distributed among them, the cells thus falling into physiological groups or tissues, each of which is espe- cially devoted to the performance of a specific function. Thus arises the ^'physiological division of labor" through which alone the highest development of vital activity becomes possible and thus the cell becomes a unit not merely of structure but also of function. Each bodily function and even the life of the organism as a whole may thus in one sense be regarded as resultant, arising through the integration of a vast number of cell-activities ; and it cannot be adequately investigated without the study of the individual cell activities that lie at its root." 64 CELL INTELLIGENCE THE CAUSE OF EVOLUTION This description is practically the same as the one I quoted earlier from our High School Physiology. You notice the same statement, that whether the structures of life are plant or animal they are based on the cell. Now the first thing the reader will want to know is this, has the cell special organs and how does it look? Fig. 3 is a j Plasmosome or I true { nucleolus I Chromatin- I network j Linin-iicivvork I KaryoRome, net-knot, or chromatin- L nucleolus Attraction-cph-re enclosing two ccntrosomes. i Plastids lying in the cytoplasm Vacuole Passive bodies (meta- plasm or paraplasm) suspended in the cy- tofplasmic mesh work Fig. 3. — The Diagram of a cell.

The cell is a complete animal made up of still smaller individuals and organs just as a larger animal is. It has a head or directing center, which seems to direct the actions of the other parts. This directing center is called the centrosome. Then it has a bunch of THE CELL 65 sub-heads or skilled workers who are located in the middle of the body of the cell. These skilled workers have charge of all work in general. They seem to be the part of the cell which contains the power, knowledge and skill to perform the different kinds of work which the cell is required to do in order to exist. These specifically skilled workers located in the middle of the body of the cell are called the nucleus, and appear to be not one individual, but a very large colony of individuals. That this part of the cell called the nucleus is the part which has the power and knowledge of how to build the differ- ent structures in life, is shown by the fact that if this is destroyed, the cell cannot do any more work nor repro- duce itself nor feed itself. In the same manner an animal is made helpless and is generally destroyed by the re- moval of its head. Besides the body, head, sub-head or skilled worker, it also has some sort of covering and a number of other special organs, not yet understood. The cells are not all of the same size. Some are more highly organized than others and very likely contain a larger number of the primordial cells of which they are composed, and other special purpose cells. The smallest are the bacteria ; then come the fungi and plant cells ; the largest are the animal building cells and those similar to them who live separate lives in the water and do not build colonies like plants and animals. My school book on botany describes these smaller cells such as bacteria, plant cells and fungi in the following language : *Tt would be hard to imagine a simpler plant, and the plant kingdom can be thought of as beginning with in- dividuals consisting of one green cell and reproducing by division. This one cell, however, absorbs material, makes food, assimilates it, conducts respiration, etc., in fact, does all the work of living carried on by plants with 66 CELL INTELLIGENCE THE CAUSE OF EVOLUTION roots, stems and leaves, although they may contain mil- lions of cells ''Bounding the cell there is a thin elastic cell-wall com- posed of a substance called cellulose. The cell-wall, therefore, constitutes a delicate sac, which contains the living substance. It is the substance that has formed the wall about itself in the same sense that a snail deposits the shell about its body. It is organized into various structures which are called organs of the cell. One of the most conspicuous organs is the nucleus, a compara- tively compact and usually a spherical body and gener- ally centrally placed within the cell. "The fungi do not contain chlorophyll and this fact forms the sharpest contrast between them and the algae. The presence of the chlorophyll enables the algae to be independent of any other organism since they can manu- facture their food out of carbon-dioxide and water. The absence of chlorophyll compels the fungi to be depen- dent upon other organisms for their food. This food is obtained in two general ways: either (1) directly from living plants and animals, or (2) from organic waste products or dead bodies. In case a living body is at- tacked, the attacking fungus is called a parasite and the plant or animal attacked, the host. In case the food is obtained in the other way, the fungus is called a sapro- phyte. For example — the rust that attacks wheat is a parasite and the wheat is the host; while the mold which often develops on stale bread is a saprophyte. "Bacteria include the smallest known living forms. Even to distinguish ordinary bacteria, the highest powers of the microscope are necessary and to study them is too difficult for the untrained student. However, they are so very important to man on account of their useful and destructive operations that every student should have THE CELL 67 some information about them. Public attention has been drawn to them chiefly on account of the part they play in many infectious diseases, in which connection they are often referred to as 'microbes' or *germs'." I have now given a general description of the different classes of cells known as plant cells, animal cells, single cells and bacteria. However, all scientists agree that they are all of the same family ; that they are all alike as far as inner structure of life is concerned ; that they differ only in size, outside covering and appearance. They use different methods of , obtaining their food and perpetuat- ing their existence. I wish to have this part perfectly clear to the reader, that all living things are either cells living singly and alone as separate individuals which we call single cells, like bacteria and others, or else a colony of cells number- ing up into the billions, like plants, animals or trees, where the cells all work together for the benefit of all. As long as the tree or animal lives, they all live, but if the tree or animal dies, it is the cells in the tree or animal that die. By reason of the high power microscope now made, it has been shown that the cell is made up of still smaller cells. These smaller units of life, which I would call primordial cells, have been described by various authors under a number of different names. The follow- ing are some of the names given to these hypothetical units of which the cell is supposed to be composed : Gem- mules, pangens, plasomes, micellae, Plastidules, Bio- phores, bioplasts, somacules, idioplasms, idiosomes, bio- gens, microsomes, gemmae. This is only a partial list of the names and they all mean the same. Each name rep- resents a different author and generally a different theory. While these theories are interesting, they are as yet only 68 CELL INTELLIGENCE THE CAUSE OF EVOLUTION theories, as the units that make up the cell are too small to be clearly seen by any microscope yet invented. It must be remembered that the cell organs that we are able to see like the centrosome, nucleus, vacuole, chromo- tophore and many others, are large crowds of these units located at different places in the cell body to perform special and different kinds of work. Some digest food, some effect respiration, some move the body, some manu- facture food, etc. As these crowds are divided up in the cell to do different kinds of work, they look different. In this way the cell has organs with which to perform its different kinds of work, just as our bodies have organs to effect different kinds of work. In reference to this, Wil- son states : **Closely interrelated as the cell organs are, they have a remarkable degree of morphological independence. They assimilate food, grow and divide and perform their own characteristic actions, like co-existant but independent organisms of a lower grade than the cell, living together in colonial, or symbionic association. Yet we may still inquire whether the power of division shown by such protoplasm masses as plastids, chromosomes, centro- somes, nuclei, may not have its root in a like power resid- ing in ultimate protoplasmic units of which they are made up. On the strength of these facts Boveri concluded that the chromosomes must be regarded as 'individuals' or elementary organisms that have an independent exist- ence in the cell. "The highest power of our present microscopes have not laid bare the ultimate organization of the cell. The cell might be composed of more elementary units ranking between the molecule and the cell, "Whether the plastids arise solely by division or also by new formation, the foregoing observations on the plas- THE CELL 69 tids give a substantial basis for the hypothesis that pro- toplasm may be built of minute dividing bodies, which form its ultimate structural basis The cell is, in Burke's words, an elementary organism, which may by itself perform all the characteristic operations of life, as in the case with a unicellular organism. . . . Even when the cell is but a constituent unit of a higher grade or organization as in multicellular forms, it is no less truly an organism and in a measure leads an inde- pendent life, even though its functions be restricted and subordinated to the common life." These statements by Prof. Wilson show that the cell, whether living his separate life in the water or other places, or acting as one of the units that make up the individual animal or plant, is an animal that has the power to perform all the functions of life. They also show clearly that all the different and separate special organs of the cell are crowds or colonies of still smaller cells or units that lead individual and separate lives within the body of the cell ; that they feed and multiply within the cell in the same manner that the cell lives a separate individual life within the body of plants and animals. It shows that when the cell divides it is simply a division of a crowd of specifically skilled workers or beings and that when the cell multiplies by division each colony of specifically skilled workers in the centrosome and nilcleus divides in two and each half then multiplies until it again reaches its original number and size when it is ready to divide again. The most wonderful thing is the centrosome or the directing center of the cell, which when the cell divides has charge of the work of looking after and seeing that the different crowds of specifically skilled workers are equally divided. The centrosome seems to be the center of intelligence 70 CELL INTELLIGENCE THE CAUSE OF EVOLUTION and will power of the cell. In regard to this part of the cell Prof. Wilson makes the following statement : ''From our present point of view, the centrosome possesses a peculiar interest as a cell organ which may be scarcely larger than a cytomicrosome, yet possesses specific physiological properties, assimilates, grows, divides and may persist from cell to cell without loss of identity. Nearly all observers of the centrosome have found it lying in the cytoplasm outside the nucleus, but apart from the protozoa there is at least one established case in which it lies within the nucleus, a fact that proves that its position is nonessential ; that the centrosome is an active center rather than a passive body or one created by the aster formation is strongly indicated by its be- havior." Then Prof. Wilson after having stated the general func- tions of the centrosome, sums up in the following lan- guage : "These facts seem explicable only under the assumption that in t-hese cases the centrosome or the substance which it carries gives an active stimulus to the cytoplasm, which incites the aster formation about itself and in words of Griffin disengages the forces at work in mitosis. "The centrosome must, however, be something more than a mere division center, for on the one hand in leu- cocytes and pigment cells, the astral system formed about it is devoted, as there is good reason to believe, not to cell division but to movements of the cell body as a whole, and on the other hand, as we have seen, it is con- cerned in the formation of the flagella of the spermato- zoon and probably also in the cilia of epithelial cells." You will see from this, that the centrosome is the party in the cell who seems to direct its several actions. It will also appear that the centrosome leads a separate life THE CRLL 71 within the cell and multiplies by division in the same manner as the cell itself. We shall now consider the functions of another im- portant organ of the cell, the nucleus. This consists of a crowd or colony of skilled workers, who perform, look after and direct the different kinds of work. You will see later on, that the nucleus has a number of crowds or col- onies specialized in different kinds of work. These col- onies are called chromatin granules or grains and when lined up for division are called chromosomes. Here is a description of the nucleus by Prof. Wilson : "The nucleus usually lies in the center, but as the outer wall thickens the nucleus moves toward it and remains closely applied to it throughout its growth, after which the nucleus often moves into another part of the cell. That this is not due simply to a movement of the nucleus toward the air and light is beautifully shown in the inner walls of the cell. The same position of the nucleus and movement of the nucleus is shown in all cases toward the place or near the place where the work is to be done." I wish to make it clear to the reader that in the con- struction of any product in the body like bile, milk or digestive fluids, it is not produced by the gland, liver, etc., but by the individual cells of which they are com- posed ; and that these individual cells are again made up of still smaller individuals, who do the actual work. You see the cell itself is a very highly organized being, just as the human body. The cells that build our body were not always in the habit of building themselves into large co-operative colonies like those w^e see now as animals, plants and trees. We find them still with other habits and methods of life, living the single and separate lives in ocean or fresh water and nearly all of them have some peculiar ways and actions that show wonderful skill and 72 CELL INTELLIGENCE THE CAUSE OF EVOLUTION intelligence. The following is a description of the pro- tozoa by Ernest Haeckel : "Many of the aquatic protozoa have the power of auto- nomous and independent locomotion and this often has the appearance of being voluntary. Among the simplest fresh water protozoa are the (arcellina) little rhizopods that are distinguished from the naked amoeba by the possession of a firm envelope. They usually creep about in the slime at the bottom but in certain circumstances rise to the surface of the water. As Wilhelm Englemann has shown, they accomplish this hydrostatic movement by means of a small vesicle of carbonic acid, which ex- pands their unicellular body like an air balloon; the spe- cific weight of the cell body which is of itself heavier than water is sufficiently lowered by this. The same method is followed by the pretty radiolaria which live floating (as plankton) at various depths of the sea. Their unicellular body is divided by a membrane into a firm inner central capsule and a soft outer gelatine covering. The latter known as the calymma is traversed by a number of water-vesicles or vacuoles. As a result of an osmotic process carbonic acid may be secreted or pure water (without the salt of the sea water) be imbibed in these "vacuoles; by this means the specific gravity of the cell is lessened and it rises to the surface. When it desires to make itself heavier and sink, the vacuoles discharge their lighter contents. These hydrostatic movements of the radiolaria attain by simple means the same end that is accomplished in the siphonophora and fishes by air filled and voluntarily contractile swimming bladders." You will notice from this description by Mr. Haeckel, that this particular kind of cell understands all the laws of hydrostatics. He understands how to make and in- flate his coat with a gas which lifts him to the surface of THE CELL 73 the water whenever he wants to go there for food or air. Whenever he gets through with his work at the surface of the water he allows the gas to escape and goes back to the bottom. I wish to call the reader's attention to these very complicated acts, showing that the cells which still live and lead a separate life possess a mind and intellect of a high order. You will notice that in the past some writers and scientists have made the remark that the cell appears to have a mind and a free will. Whether they have or not will be a question for the reader to determine for himself after having read this book. It has taken man a long time with a mind and free will to rise from the savage state to civilized life. Intelligence and free will have placed man where he is today and I believe that the same forces have been back of the progress and development of cell life which is back of man. One writer makes the following statement about the single cells living in the sea: "A great number of classi- fications for the methodical distribution of these beings has been proposed but not one of them is altogether satisfactory. Some inhabit fresh and salt waters, serving as food for a great many other organisms or contributing by means of their calcareous or silicious skeletons to the formation of continents. Others live as parasites in the organs of animals and plants and induce more or less serious disorders in the constitutions of the organisms they have penetrated. Others again, acting like ferments produce important chemical modifications in organic matter in the course of decomposition." You will notice from this statement that the cell is able to effect chemical modifications and changes in organic matter. This would seem to clearly indicate that the cell is familiar with the laws of chemistry. Mr. Ernest Haeckel makes the following statement about the 74 CELL INTELLIGENCE THE CAUSE OF EVOLUTION cell : **When the cell-theory developed in the course of the last half century, the common anatomic ground work of all living forms w^as recognized in the cell, and the conception of the cell as the elementary organism led to the further belief that our own frame like that of all the higher animals and plants is a cell state composed of millions of microscopic citizens, the individual cells, which work more or less independently therein and co- operate for the common purposes of the entire commu- nity. This fundamental principle of the modern cell- theory was applied with great success by Rudolph Vir- chow to the diseased organism and led to most important reforms in medicine. The cells are in his view inde- pendent 'life units'." The reader will notice from this that the cell is now looked upon as a separate Hving in- dividual and that in plants and animals cells live together in a co-operative community. It seems to be the aim in nature to improve and de- velop. Improvement in a social way can come only at the cost of some of the liberties of the individual citizen. In proportion as society organizes itself and rises in scale, so does a shrinkage enter the private life of each of its members. In order to obtain the comforts and security of society the individual must abandon some of his personal liberties and work towards one purpose, the economic and political perfection of the race. Is it not wonderful that plants and animals happen to be perfect political and economic organizations of individual cells, just like our own organized society? Think of the count- less billions of cells that have gone down in a terrific struggle with the elements in the past ages, in order to place civilized man in his secure and comfortable home. We look down at the actions of the cell like a man looking at us from the sun or another world, never think- THE CELL 75 ing that we are looking at our maker through a telescope made by him, the eye. It is no wonder that man, who was built and guided by the intelligence of the cell, was able to organize himself into a higher civilized life, be- cause his builder had gone through all those experiences before. The customs, laws, virtues political and eco- nomic, nof. G. Crowd of skilled workers beginning to divide. F.

Who is this most wonderful being, the centrosome, who directs these actions? Seen through the most powerful micrp- FiG. 6. — Centrosome highly magnified. — Wilson. scope, he looks like an individual who is in touch with all the other individuals around him by some method or means that is not yet understood. He seems to be con- nected with everything in every direction as you will see from the illustration. In reference to the work of the centrosome Mr. Wil- THE CELL 81 soil makes the following remark: "The division of the cytoplastic granules must remain a quite open question, yet we should remember that in dividing plastids of plants cells are often very minute, and that in the centro- some we have a body no larger in many cases than a microsome, which is positively known to be in some cases a persistent morphological element, having the power of growth, division and persistence in the daughter cells. When we consider the analogy between the centrosome and the chromatin grains, when we recall the evidence that the latter graduate into the oxychromatin granules, and these in turn into cytomicrosomes, we must admit that Burke's cautious suggestion that the whole cell might be a congerie of self propagating units of a lower order is sufficiently supported by facts, which constitute a legitimate working hypothesis." You wall see from this that the general opinion of scientists is that the cell is a colony of still smaller cells or beings ; and that the centrosome is simply one of these smaller cells specifically in charge and organized to be the general director and manager of the whole organiza- tion we call the cell. Figure 7 of the centrosome shows clearly that it is in contact with every part of the body of the cell. The reader can clearly see that the individuals organized together to make the complete whole we call cell are too small to be clearly seen and to have their individual actions studied. Now we come to consider the most wonderful per- formance in plant and animal life, which are the repro- ductive actions of the cells that build plants and animals. As the reader probably knows, all life we see, such as plants and animals, begins as one single cell. In ref- erence to this point Prof. Drummond makes the following remark : "The embryo of future man begins life like the 82 CELL INTELLIGENCE THE CAUSE OF EVOLUTION primitive savage in a one room hut, a single simple cell.. The cell is almost microscopic and round in shape. An outer covering almost as transparent as glass surrounds this little body and in the interior imbedded in the proto- plasm lies a bright globular spot ; in form, size and com- position there is no difference in this cell and that of any other animal. The dog, elephant, lion and a thousand others begin their lives the same v^ay. At an earlier stage before it has taken on its pellucid covering, this cell has affinities, still more astounding for it is a fact in modern science that the first embryonic abodes of moss» fern, pine, shark, crab, lizard, lion and man are so ex- actly similar that the highest power of microscope and mind fail to trace the smallest distinction between them." You will see from this statement by Mr. Drummond that what I have told you heretofore is true, that every- thing starts from one single cell. That they are all alike except as to outside covering and size. The cells that build man, mouse or plants look alike in the same way that a shoemaker and a preacher look alike, but their knowledge and experience in life have been different. For that reason the work they do and the structures they build will be different, depending on what their education and experience have been. The actions of a living being are based on his knowledge, derived from previous experi- ence. To return to the question, — where does this first cell come from : When the cells build the animals, special organs are built in the male and female where the cell is prepared, educated and dressed up ; these are the sex organs. In a certain place in the female bodies, arrange- ments have also been made to furnish these cells with food and building material, so they can multiply and build another body. This place is called the womb. Now THE CELL 83 how do they prepare for this act of meeting in the womb for the purpose of building a new body? In the overies of the female the cell prepares for the occasion in this way : It discharges on dispenses with half of the skilled workers located in the nucleus, and also its centrosome or general manager and provides itself with food Fig. 7. — Structure of the centrosome in the polar asters. — Wilson. enough to last several days. With this food she goes into the womb and waits for the cell to come from the male. How is he prepared? He also discharges or abandons half of his skilled workers in the nucleus but keeps the general manager or centrosome, so when the two meet and join their forces together, there will be a complete cell with a full nucleus, centrosome and also food enough to last them until connections have been built up in the womb with the body, where they can obtain and be fur- nished with such food and building material as will be 84 CELL INTELLIGENCE THE CAUSE OF EVOLUTION required to build the new structure. I must further de- scribe the male cell, who makes elaborate preparation to be able, not only to meet the female cell, but to be able to be the first one to reach her in the piighty race and strug- gle that takes place between a thousand or more of them in a dash for the goal. The male cells, or spermatozoons, who prepare to meet the female cells in the womb, change their form so com- pletely that no one not familiar with them could possibly recognize them as a human cell. They were thought to be parasites when first discovered and not in any way connected with or a part of the body. The male cell is re- constructed to eflfect a certain purpose, which is to push its way through obstacles in a competitive race that is to take place by thousands of individuals at the same time. To be swift and effective, the centrosome is placed in front, protected by a hard point ; next, back of him is the entire crowd of skilled workers known as the nucleus ; then back of them there is a powerful tail or propeller, constructed from the common workers and laborers of his whole body, which is designed to push the male cell with the centrosome in front, directing the course to the place where the female cell is waiting for him in the womb. The following is a description from Prof. Wilson of the male cell generally called the spermatozoon : **Tn its more usual form the animal spermatozoon resembles a minute, elongated tadpole, which swims very actively about by the vibrations of a long slender tail. Such a spermatozoon consists typically of four parts. Fig. (8). First — The nucleus, which forms the main portion of the head and consists of a very dense and usually homo- geneous mass of chromatin staining with great intensity. It is surrounded by a very thin cytoplasmic envelope. THE CELL 85 Apical body or acrosome. Nucleus. End-knob. Middle-piece. Enveltps af the tail. . Axial filament. End-piece. Fig. Fig. 8.— Diagram of the flagellate spermatozoon.— Wilson. Second— An apical body, or acrosome lying at the front end of the head, sometimes very minute, sometimes al- most as large as the nucleus and in some cases terminat- ing into a sharp spur by means of which the spermatozoon bores its way into the ovum. 86 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Third — The middle piece, or connecting piece, a large cytoplasmic body lying behind the head and giving at- tachment to the tail from which it is not always distinctly marked off. At its front end it is in some forms (mam- mals) separated from the nucleus by a short clear region, the neck. Fourth — The tail, or flagellum, in part at least, a cyto- plasmic product, developed in connection with the cen- trosome. From a physiological point of view we may ar- range the parts of the spermatozoon under two categories as follows : First — The essential structures, which play a direct part in fertilization ; these are : (a) The nucleus which contains the chromatin, (b) The middle piece, which either contains a formed centrosome or a pair of centro- somes (end-knob), or is itself a metamorphosed centro- some. This is probably to be regarded as the fertilizing element par excellence, since there is reason to believe that when introduced into, the egg, it gives the stimulus to division. Second — The accessory structures, which play no direct part in fertilization, viz ; (a) The apex, or spur, by which the spermatozoon attaches itself to the egg or bores its way into it. (b) The tail, a locomotor organ, which carries the nucleus and centrosome, and as it were, de- posits them in the egg at the time of fertilization. There can be little doubt that the substance of the flagellum is contractile and that its movements are of the same nature as those of ordinary cilia. Ballowitz's discovery of its fibrillated structure is therefore of great interest as indi- cating its structural as well as physiological similarity to a muscle fibre. "Tailed spermatozoa conforming more or less nearly to the type just described are with few exceptions found THE CELL 87 throughout the metazoa from the coelenterates up to man." The reader will see from this statement, Fig. (8), by Prof. Wilson, that it appears clearly the male cell is a structure built up and composed of a multitude of still smaller primordial beings ; that the central part of the cell, the nucleus, contains those who are skilled and under- stand the work that has been done and is to be done in the future, and that the centrosome is the directing center and general manager whose duty it is to guide the actions of all ; that the main body of the cell which is called cyto- plasm, contains the common laborers and servants, who work and act from instructions and orders given by the skilled workers or centrosome. We see that the male cell in this race to find the female cell employs the entire force of common laborers in the body of the cell to push and carry him to the desired place. Consider for a moment this preparation of thousands who are willing to prepare for this race, where all but one must fail to reach the goal, and all but one must perish. However, it is a fair race, based on the law of evolution, that the best man in a struggle for existence will win. In this act, as in all other schemes in nature, where there is intelligence there is authority, design, purpose, wisdom and victory. Here it seems that microscopic and mysterious beings we call the centrosomes are able to direct all the other micro- scopic beings in the cell to subjugate and organize mat- ter, so as to create for themselves an existence on the planet. It appears that the centrosome is the real source of will and intelligence in the cell, just as the brain cells are the source of intelligence in animals and man. This male cell of animals is so very similar in shape and actions to male cells or spermatozoons of plants and in- sects, and also cells living a single and separate life in 88 CELL INTELLIGENCE THE CAUSE OF EVOLUTION the water, that I shall quote a description of them from Ernest Haeckel. "The same may be said of the traveling spores of many of the algae and of the most remarkable of all ciliated cells, the spermia or spermatozoa of plants and animals. As a rule they are cone shape, having an oval or pear shape, (though often also rod shape) head, w^hich tapers into a long and thin thread. When their lively move- ments were first noticed in the male seminal fluid (each drop of which contained millions of them) two hundred years ago, they were thought to be real independent ani- malcules like the infusoria and so obtained their name of seed animals (spermatozoa). It was a long time (60 years ago) before we learned that they are detached glan- ular cells, which have the function of fertilizing the ovum. It was discovered at the same time that similar vibratory cells are found in many of the plants (algae mosses and ferns). Many of the latter (for instance, the spermato- zoids of the Cycadea) have instead of a few long whips, a number of short lashes (cilia) and resemble the more highly developed ciliated infusoria. **The ciliary movement of the infusoria is held to be a more perfect form of vibratory movement, because the many short lashes found on them are used for different purposes and have accordingly assumed different forms in the division of labor. Some of the cilia are used for running or swimming, others for grasping or touching and so on. In social combination we have the ciliated cells of the ciliated epithelium of the higher animals — for instance, in the lungs, nostrils, and oviducts of verta- brates." The reader will clearly see from this description by Mr. Haeckel, that the male cell of man, animals and plants is THE CELL 89 in no way different from the other single cells leading a single life in the water. That he is a very active animal with organs of touch, locomotion, and a great number of others to assist him in his life. Many male cells of dIji.i< and animals swim about in the water for a long time and long distances in search of the female cell. It sh(. -.s clearly that at the start we are just what Prof. Drum- mond stated, "Apparently no different from plants in- sects, and animals." These tiny microscopic beings will of their own free will go ahead and multiply into groups, and tie and arrange themselves into the different shapes and forms we afterwards call plants, animals or man. By this time, I think the reader must see that the cell is the one who is at the base and is* the cause of life that we see, as in plants and animals. He is the cause of nil living structures. He multiplies by division, as hereto l>re described, and with the building material at hand or fur- nished by other cells, the work continues until the plant or animal is completed. We see him move about from place to place in search of food and material for his struc- ture just as other animals do. We know that he requires food, air and water just as we do. We know that he understands how to select the right kind of material at the right time and with it, build the most intricate and complicated structures. We kn(»w this because we see him do it and from these facts, we must naturally conclude that he acts in a similar mai-ner to other animals including man. We find that he acts for a purpose. When man acts for a purpose, we say he is intelligent. When a person is able to produce any t^truc- ture by reason of being intelligent, we mean that he is instructed or skillful in the particular work which he does. When a large building is being constructed, it seems in 90 CELL INTELLIGENCE THE CAUSE OF EVOLUTION the distance to simply grow larger from day to day ; it appears in the distance to take form slowly and impercq:)- tibly. If we could never get near enough to the building to clearly see what was going on, we would be compelled to say that it simply grew. Why? Because we had not eyes powerful enough to see what was being done ; but with -the aid of the telescope we could increase the power of our eyes to see more clearly and determine the facts, that the building was not being formed by magic but by the work and industry of a number of human beings. So it is in every day life, we see a tree or plant or animal grow. That is as far as we can see. By increasing the power of our eye with a miscoscope, we can see that it does not simply grow, as by magic, but that it is being constructed in the same manner as a building would be by man. Every part of the plant is occupied by active individuals, con- tinuously at work, feeding themselves, multiplying and building the plant or animal or its parts. We shall again consider what takes place in the process of division of the cell. All modern authority now seems to agree that the cell itself is a colony of beings, organ- ized to work together for the mutual benefit of all. From the fact that not only the cell itself, but also each specifi- cally skilled crowd of workers contained in the nucleus divides exactly in two equal parts, so that each cell gets exactly its equal half of the skilled workers, makes it clear that those individuals of the cell who are concerned with the work of building and keeping a record of past experiences, which we call memory, are at all times kept double or in duplicate. After the crowds have divided as takes place in the division of the cell, another division will not take place until that crowd has again doubled. It seems clear to me that those chromatin granules, as they are called, are individuals or primordial beings possessed THE CELL 91 of the special knowledge and skill of building those struc- tures from whence they came. The fact that the centro- some, who takes charge of the act of division, causes such division to be exactly equal, tends to show a definite pur- pose to divide the specifically skilled working force equally. How this force of individuals is again able to grow and increase in the cell to its full number and size, the microscope is not yet powerful enough to disclose to us. However, we can clearly see that it does again in- crease and grow to its original number and size. In the act of fertilization where the male cell prepares to meet the female cell, it is clear that each one knows what the other is going to do and acts accordingly. The female cell must know that the male cell will bring a cen- trosome or general manager and the male cell must know where to look for the female and also have some idea what she will have and what she looks like. They must have the faculty of memory, skill and intelligence to do these things. Every act connected with this performance of the male and female cells of preparing for and meeting in the womb, is an intelligent act requiring judgment and will, which must be based on memory. We do not know how the cells in our brain can remember past experiences, but we know it to be a fact. We know every cell in our body including our muscles must also be possessed of this faculty of memory, just as the cells composing our nerves and brain are, if not we could learn nothing from practice nor form a habit. Habit is based on the mem- ory of the cells of that part of the body trained or prac- tising. By. repetition the acts are fixed in the memory of the cells in the muscles that take part in the act, and fin- ally they are remembered and then we call them habit. We have seen that the cell is an individual again com- posed of individuals called granules ; that these granules, 92 CELL INTELLIGENCE THE CAUSE OF EVOLUTION usually called chromatin granules, group themselves into crowds v^ho have their own specific work to do in the same way that in our body we have special colonies or crowds of cells, who have special work to do and are called organs, like the heart, liver, lungs, stomach, etc. So in the cell the skilled crowds, who each have their spe- cial work to do in the body of the cell, are called organs. There is the centrosome, who is the directing center or general manager of the whole cell body. Then there is the nucleus, that contains an enormous number of crowds, each skilled in his particular kind of work, as we shall see later. Then there is the group that has nothing to do but make starch for food. This crowd of special workers are found only in the plant building cells and those plants who are able and understand how to make their own food out of the raw material of earth, air and water. Then there is the crowd of general workers, which you might call common laborers, who compose the main body of the cell. How do the cells communicate with each other? That they have some method of certain and rapid com- munication is clear, and is evidenced by the rapidity with which sensations and ideas are transferred from one place of the body to the other. It has been demonstrated that the nucleus in one cell will take charge of the common laborers and workers in another cell, who have been de- prived of their nucleus. Here is Prof. Wilson's statement of those experiments : "If correct, these experiments give clear evidence of transference of physiological influences from cell to cell by means of the protoplasmic bridges, showing that the nucleus in one cell may thus control the membrane-forming activity in an unnucleated fragment of another cell." This is very significant in showing with what loyalty they co-operate and work together for the general welfare of the entire colony or body. THE CELL 93 I must here explain to the reader more about the repro- ductive cells of plants and animals, — how they differ from those cells that build the body. They are called germ cells and as you remember, the male cell is called the sper- matozoon and the one that comes from the female is called the egg. -However, the reader must not forget that the egg and spermatozoon are cells, in every way just alike, except that they are built and prepared to perform differ- ent kinds of work and for that reason, they look different. The egg or female cell is prepared to just sit and wait for this spermatozoon with food for both to last them until they can be connected with the nourishment from the body. The spermatozoon is built with a powerful pro- peller with which he is enabled to push his way through obstacles and obstructions in a mad competitive race with thousands of others, who all start at the same time in search for the same object, the female cell. This act of the spermatozoon and female cell meeting and joining is called fertilization. You remember that the nucleus, which always contains the same number of specifically skilled crowds of workers, always divides exactly in two whenever the cell reproduces itself or multiplies by divi- sion. Now it is also a singular fact that the cell from the female and also from the male discharge just half of the specifically skilled crowd of workers in the nucleus, which are called chromosomes, so that when the male* and female cells get together and find each other, and the two join together to form one cell, the two together will be a complete cell, and will have a full number of specifically skilled workers, and the correct number of chromosomes. The body cells or cells that build the body are called somatic cells, and are always a little different from the germ cells. Whenever these cells, which build the body, begin their task,— as a liver cell, or muscle cell,— they 94 CELL INTELLIGENCE THE CAUSE OF EVOLUTION first discharge or dispense with a part of their nucleus or specifically skilled workers; according to the kind of work they have to do. These facts are very significant in that they prove that the nucleus contains groups of workers specifically skilled in all the departments of work per- taining to the building of the body. When a cell takes charge of the work of building and maintaining the liver or lungs it retains only that group of specifically skilled workers who understand that particular line of work, and discharges all the others. In reference to these facts, I will here quote some more from Prof. Wilson : "The germ from which every living form arises is a single cell derived by division of a parent cell of the pre- ceding generation. In the higher types the germ cells are more or less definitely organized in groups supported and nourished by somatic cells, specially set apart for that purpose, and forming distinct sexual organs, the ovaries and spermaries, or their equivalents. Within these organs the germ cells are carried protected and nourished and here they undergo various differentiation to prepare them for their future functions. The structural difiference thus brought about between the germ cells is, however, only the result of physiological division of labor. The female germ cell or ovum supplies most of the material for the body of the embryo and stores the food by which it is nourished. It is therefore very large and contains a large amount of cytoplasm laden with food matter, and in many cases becomes surrounded by membrane or other enve-* lopes for the protection of the developing embryo. On the other hand the male germ cell or spermatozoon con- tributes to the mass of the embryo only a very small amount of substance comprising as a rule only a single nucleus and a very small quantity of cytoplasm. It is thus relieved of the drudgery of making and storing food THE CELL 95 and providing protection for the embryo and is provided with only sufficient cytoplasm to form a locomotor ap- paratus by which it seeks the ovum. It is therefore very small and performs active movements. The plant ovum which is usually known as the oosphere shows the same general features as that of animals. The flagellum or tail is merely a locomotor organ, which plays no part in fer- tilization. Its most characteristic feature is the axial fila- ment, which is composed of a large number of parallel fibrillae like a muscle fibre. Both the ova and spermato- zoon take their origin from cells known as primordial germ cells, which become clearly distinguishable from the somatic cells at early period of development and are at first exactly alike in the two cases. Moreover, from the outset the progenitors of the germ cells differs from the somatic cells not only in the greater size and richness of chromatin of its nuclei but also in its mode of mitosis, for in all those blastemers destined to produce somatic cells, a portion of the chromatin is cast out into the cyto- plasm where it degenerates and only in germ cells is the sum total of the chromatin retained. Only the germ cells receive the sum total of the egg chromatin handed down from the parent. All of the somatic cells contain only a portion of the original germ substance. The original nuclear constitution of the fertilized egg is transmitted as if by law of primogeniture, only to the one daughter cell and by this again to one and so' on. While in the other cells, the chromatin in part degenerates, in part is trans- formed so that all of the descendants of these side branches receive small reduced nuclei. The number of chromo- somes arising from the germ nuclei is always the same in both and is one-half the number characteristic of the tis- sue cells of the species. The two nuclei do not fuse, but 96 CELL INTELLIGENCE THE CAUSE OF EVOLUTION only place themselves side by side and in this position give rise each to its own group of chromosomes." "The difference between the two sexes is probably due to the physiological division of labor between the two germ cells, the spermatozoon being motile and very small, while the egg contains a large amount of protoplasm and yolk. The evidence is steadily accumulating, that reduc- tion is accomplished by two maturation divisions through- out the animal kingdom, even in the unicellular forms. The one fact of maturation that stands out with perfect clearness and certainty amid all the controversy sur- rounding it, is a reduction of the number of chromosomes in the ultimate germ cells to one-half the number char- acteristic of the somatic cells. It is equally clear that this reduction is a preparation of the germ cells for their subsequent union and a means by which the number of chromosomes is held constantly in the species." You will notice that the actions of the individuals which compose the cell show that they are very careful not to lose any of the crowds of specifically skilled workers ; that great care is exercised to see that the division is ex- actly equal. The one w^ho always takes charge of the act of division is known as the centrosome. You will also notice from Mr. Wilson's statement, that the group of workers in the nucleus do not ''fuse," as we used to think when we did not have microscopes powerful enough to see what became of them. You will notice that they sim- ply remain side by side and apparently do so during the entire life of the individual. From the evidence before us now it begins to look quite clear how the cell can and does build a structure like a plant or animal. A cell is a com- bination of a multitude of highly organized and special- ized primordial beings. The cell contains in itself num- erous crowds of specifically skilled workers, numbering THE CELL 97 thousands or millions. How these primordial beings that make up the cell actually multiply and grow, we have no means of knowing nor microscope to tell us. You see life is based on organization and specialization. When the cell multiplies by division there is simply an equal division of the colony of specifically skilled workers in the cell, which is called the nucleus. In this way, you can clearly see, that the knowledge, skill and experience possessed by the cell or more correctly speaking, by the individuals com- posing the cell, and which they have accumulated through the past ages of experience, is handed on to posterity and preserved. It is a singular thing how everything works out accord- ing to a preconceived plan; how exactly one part is made to meet or fit into another part in the course of develop- ment The spermatozoon knows what the female cell will have to start in life with so he comes to meet her pre- pared accordingly. The female cell seems to know what the spermatozoon will bring, so she leaves those same things behind. She knows what he will have to contend with in his struggle to reach her and that he cannot be bothered with carrying a food supply, so she provides the food She seems to know how much she will need and how long it will take the body cells to connect them with food supply from the body. In several species special food carriers are provided, which are called nurse cells. They stay with the germ cells and furnish them with food until they get started in life. Here is what Prof. Wilson has to say about them : -As the primordial germ cells enlarge and form the mother cells of the .gg, they almost invariably become intimately associated with neighboring cells, which not only support and protect them but also serve as a means for the elaboration of food for the growing egg cells. In 98 CELL INTELLIGENCE THE CAUSE OF EVOLUTION most cases, as ovarian development proceeds, definite as- sociation is established between the egg and surrounding cells. As a rule the material elaborated by the nutritive cells is passed into the egg either in solution or in the form of granular protoplasmic substance. In some form each egg is accompanied by a single nurse cell attached to its side with which it floats free in the body cavity. The nurse cell is at first much larger than the egg cell. The egg cell rapidly grows, apparently at the expense of the nurse cell, which becomes reduced to a mere rudiment, attached to one side of the egg and finally disappears. In mysostoma, the young egg is accompanied by two nurse cells, one at either end." This shows clearly that the germ cells, as they start out from one body with the intention of building another and new body, are generaly provided with food to give them a start in life; and in many cases separate cells or servants are provided who go with them and carry the food for them. The reader must be able to see at this time that the cells in all the details of their inner life act precisely as we do. They act with a purpose and accord- ing to a preconceived plan. Why should they act diflfer- ently ? The ideas that direct our actions are nothing more than the ideas of cells located in our head, who have charge of that particular work in our bodies of thinking and directing our actions. There must have been a time in the past million years when those primordial cells that make up the cell and which they call chromatin granules, lived separate and single lives alone in the world, just as a great number of species of the single cell are doing today. You might say that from the way it looks, the cell is not the real builder but that the real builder is the primordial cells that have associated together and organized this individual we call THE CELL 99 cell. However that may be, the cell is clearly a separate living individual or animal regardless from v^hat he is organized or of what composed. Ernest Haeckel states, 'The cells are individual life centers, and the uni- fied life of the whole maa is the combined result of the work of his component cells. In this way the cells are the real life units of the organism. Their individual inde- pendence is at once seen in the permanently unicellular protists of which several thousand species are already known to us." It appears that the cell has organs with which it is able to see, feel and hear. Still I do not see how they can have these organs in the same sense that we consider hearing and seeing. Here is what one scientist has to say about the cell possessing organs of sight and hearing: "It is impossible to believe that these organs are not eyes for they have the same structure as eyes of comparatively higher classes of animals, such as certain worms, tubu- laria, rotifers, lower class crustaceans, etc. All these or- gans are similarly formed of a small crystalline globule inclosed in a small mass of pigmentary matter. The iden- tity of structure naturally leads to the assumption of the identity of functions." Ernest Haeckel claims for the cell a definite mouth and annus. Here is what he has to say : *'The great class of rhisopods is distinguished by the fact that their naked plasma bodies can take in ready formed solid food at any point of the body. On the other hand most of the infusoria have a definite mouth opening in the outer walls of their unicellular bodies and some- times a gullet tube as well. Besides this cell house we usually find also a second opening for the discharge of indigestible matter, a cell annus." Prof. Haeckel has also been able to see the movements 100 CELL INTELLIGENCE THE CAUSE OF EVOLUTION of the primordial cells inside of the cell and this is what he says in reference to their appearance : ''In the rhizopod, the remarkable protozoan who as a unicellular organism sheds so much light on the obscure wonders of life, we notice a curious streaming of the gran- ules in the living plasm. Within the cytoplasm of the amoeba particles travel up and down in all directions." The following is Prof. Haeckel's observation in refer- ence to how they act in conjugation : "When two ciliated Infusoria conjugate, they place themselves side by side and connect for a time by means of a bridge of plasm. A part of the nucleus of each has already divided into two portions, one of which functions as the female standing nucleus and the other as the male traveling nucleus. The two mobile nuclei enter the plasm bridge and move through it, pushing against each other into the body of the opposite cell ; they then coalesce with the deeper lying standing nucleus. When the fresh nu- cleus has thus been formed (by amphimixis) in each of the copulating cells, they again separate. The two re- juvenated cells have once more acquired the power to propagate for a time by division." Mr. Binet, who believes the cells show a psychic phe- nomena, makes the following remarks : **The sexual ele- ments and especially the spermatozoid of, all unicellular organisms are certainly the ones which show the most highly developed psychical functions : the act of seeking and approaching the ovule, which is frequently situated at quite some distance from where the male element is de- posited ; the length of road to be traveled ; the obstacles to be overcome ; all point to faculties in the spermatozoid that are not explainable by simple irritability." The reader by this time will see that not only has the cell all the special sense organs possessed by animals in THE CELL 101 general but in addition has others, the purpose of which is not yet understood ; and that it performs all the actions and functions of life performed by animals. It must begin to appear to the reader at this time that the cell must have a mind and intelligence similar to our own. How- ever, the scientists of today do not seem to so consider it. Therefore, I must use these statements of others in refer- ence to the actions of the cell to demonstrate my conten- tion. We shall now consider their method of nutrition and respiration. The reader must remember that the cell is a perfect and complete animal, that it must have food, air and protection from the elements in the same manner as a human being. While it has been quite conclusively shown heretofore that the cell must have oxygen from the air and also food in order to exist, I shall quote a few statements from scientists to show the actions and re- quirements of the cells. "There seem to be three classes or methods by which cells obtain their food, viz : First — The plant cells that make their own food from the raw material of earth, air and water through chemical action brought about by the aid of sunlight. Second — Saprophytic beings who live on decayed or dead matter. Third — Those that live on other lives. The second class are called scavengers and the third class parasites." I shall here quote Mr. Binet, who makes the statement, that the actions of the cell show choice and discretion; and this is what he has to say in reference to their mode of nutrition : "Nutrition by endosmosis, or saprophytic. The organ- ism nourishes itself by absorbing through the whole sur- face of its body, liquids containing the products of vege- 102 CELL INTELLIGENCE THE CAUSE OF EVOLUTION table or animal decomposition. Saprophytic beings are found in putrid waters or in infusions. ''There is now a last mode of nutrition, of which we shall treat in minute detail ; viz., animal nutrition, where the micro-organism seizes solid alimentary particles and nourishes itself after the fashion of an animal, whether it be by means of a permanent mouth or by means of an adventitious one improvised at the moment of need. "Animal nutrition requires very remarkable psycholog- ical faculties in the organisms practising it. These mani- festations of psychic life, the progressive complexity of which we intend to trace in starting from the simplest protozoic forms and arriving at the higher, prove that these animalcula are endowed with memory and volition. ''The micro-organisms do not nourish themselves in- discriminately, nor do they feed blindly upon every sub- stance that chances in their way. Also when they ingest food through some point or other of their bodies, they un- derstand perfectly how to make a choice of the particles they wish to absorb. This choice is sometimes quite well defined, for there are species which feed exclusively upon particular foods. Thus there are herbivorous Infusoria and carnivorous Infusoria. Among the herbivorous ones may be classed the chilodons, which feed upon small algae diatomaceae and Oscillaria. The paramecia live princi- pally upon bacteria, the leucophrys is a specimen of the carnivorous class. It devours even the smaller animals of its own kind." "The Bodo caudatus is a voracious flagellate possessed of extraordinary audacity. It combines in troups to at- tack animalcules 100 times as large as itself as the colpods for instance, which are veritable giants when placed along side of the Bodo. Like a horse attacked by a pack of wolves, the colpod is soon rendered powerless ; twenty, THE CELL 103 thirty, forty bodos throw themselves upon him, eviscerate and devour him completely (Stein)." Here is what Mr. Haeckel has to say about the parasitic habits of some cells. ''By parasites in the narrower sense, we understand in modern biology only those organisms which live on others and derive their nourishment from them. They are numer- ous in all the chief divisions of the plant and animal king- doms and their modifications are of great interest in con- nection with evolution. No other circumstance has so profound an influence on the organisms as adaptation to a parasitic existence. "I have already spoken of the many peculiarities of me- tabolism in the ubiquitous bacteria ; while many of them cause putrefaction, they at the same time feed on the parts of other organisms which have died. The fungi feed for the most part on the decayed remains of plants and the product of putrefaction which accumulates on the ground. In this character of scavengers they play the same important part on land as the sponges do at the bot- tom of the sea." I must here tell the reader something about the cell colony called the volvox : These cells bunch themselves into colonies of about twelve thousand individuals. Some are male and female and some only workers or neutrals. The common labor- ers or neutral cells are all provided with hands which they use to push and propel themselves through the water backwards or forwards like a raft or submarine. Five thousand like the galley slaves of old paddle the water with their arms at the same time and in that way trans- port the other seven thousand males and females to such places as they may choose to go. Just consider this for a minute : a boat or raft pushed through the water by five 104 CELL INTELLIGENCE THE CAUSE OF EVOLUTION thousand individuals, all working under the command of some one cell directing their course. They must neces- sarily work under the direction of one cell or else how could all these five thousand individuals push or pull in unison. How could they all pull or push together the same instant in order to go either forward or backward unless there was someone in command to give the orders when to go either forwards or backwards. This shows clearly how the cells are able to organize themselves so as to work together in harmony to affect their purpose. Still it is but a very crude organization as compared with the high state of organization and co-operation practised by the plant and animal building cells. Here is what Mr. Binet has to say about this colony of cells called the volvox : "In the genus of volvox colonies are found of which the structure is very complicated. Such are the great green balls formed by the aggregation of diminutive or- ganisms, which form the surface of the sphere and are joined together by their envelope. They have each two flagella which pass through the inclosing membrane and swing unimpeded on the outside ; the envelopes each tightly holding the other form hexagonal figures exactly like the cells of a honeycomb. Each volvo:?^ is at liberty within its own envelope, but it projects protoplasmic ex- tensions, which pass through its cuticle and place it in communication with its neighbor. It is probable that these protoplasmic filaments act like so many telegraphic threads to establish a net work of communication among all the individuals of the same colony. It is necessary, in fact, that these diminutive organisms be in communica- tion with each other in order that their flagella may move in unison and that the entire colony may act as a unit and in obedience to a single impulse. The number of micro- THE CELL 105 organisms constituting a volvox colony is quite consider- able ; as many as twelve thousand have been counted. "It was upon analogous phenomena that Gruber based the existence of a diffused nervous system in the stentors. The same line of reasoning may be followed in the case of the volvox. Since unanimity of movement is demonstra- ble among twelve thousand micro-organisms constituting a colony, it must be inferred that their movement is regu- lated by the action of a diffused nervous system present in the protoplasm. This conclusion is all the more interest- ing from the fact that these volvox are vegetable micro- organisms. In the dioecian volvox the female cellules and male cellules are joined together by themselves in separate colonies. When the time of fecundation arrives the male cellules scatter and proceed to conjugate with the female cellules. The colony which bears the female cellules also contains neutral cellules which are not desig- nated for fecundation ; the latter simply perform a loco- motive function ; equipped with one eye and two flagella, they are intended to move the great colonial ball ; they are the oarsmein of the colony. The volvox male, female and neutral all seek the light, whether solar or artificial and settle near the surface of the water. As soon as the female colonies have been fecundated, the oospores change their color, they turn from green to an orange yellow. At this time the colony is seen to draw away from the light and to disappear from the surface of the water. This change of position is affected by means of the vibratile cilia with which each neutral cell is furnished and which projects beyond the gelatinous sphere. Now as no change of color or form is noticed in the neutral cells after fecundation, it may be asked from what cause they flee from the light which they formerly sought." You notice he ends by asking why they leave the light 106 CELL INTELLIGENCE THE CAUSE OF EVOLUTION which they formerly sought. Now to me that is very clear. These volvox cells are of the plant species. They understand how to make their own food and building ma- terial from the raw material at hand by the aid of sun- light. They row their raft into the sunlight now and then in order to make food consisting generally of starch and such other material as they need and when they get through, they move into the shade to rest up and enjoy themselves. There is one method practised in reproduction by the smaller cells like bacteria and plant building cells, that is, the forming of spores, which I must mention here briefly. A spore is a cell protected with a hard covering against wind, weather and climate, wherein it can remain until favorable conditions shall arise to perform the or- dinary functions of life or to begin the building of a new structure. Some spores, however, are able to swim about actively until they find their mates or places to locate and build their new structures, whether plant or animal. The following is from our High School Botany in re- gard to these individuals called spores : ''Any one of these cells may produce within itself a sin- gle large swimming spore, which escapes from the mother cell into the water. At its more pointed clear end, there is a little crown of cilia by means of which it swims about rapidly. These spores finally anchor themselves and each one produces a new filament. It has been observed that these small swimming cells come together in pairs and fuse, each pair thus forming one new cell. The cell thus formed passes through a resting period (usually during winter) then begins to grow and finally produces four swimming spores, each of which is able to produce a new filament of ulothrix. Here is evidently a third method of reproduction, which is peculiar in the fact that two spe- THE CELL 107 cial cells unite to form the spore that produces the new cell. "When these cells formed by internal division escape from the mother cell into the water, it is discovered that they are able to swim about by the lashing movements of four cilia, that appear in a cluster at the pointed end. "A special cell thus set apart for reproduction is called a spore, and spores that swim are distinguished as swim- ming spores. A very important fact about ulothrix there- fore is that it reproduces not only by vegetable multipli- cation but also by swimming spores. "In other cells of the same filaments, or in cells of fila- ments under different conditions, the same formation of cells by internal division may be observed, but the con- tained cells are smaller and more numerous. When they escape it is discovered that they also are ciliated swim- ming cells but since they do not produce new filaments, it is evident that they are not swimming spores." I think I have now covered in a general way the most important features connected with the inner life of the cell. I might mention that the ability of the cell to pro- vide itself and build around itself protective coverings and armor of dififerent materials and designs, from a soft flexi- ble covering to one as hard as flint, has been the stepping stone by which the cell has been able to build the many peculiar structures, and to display the marvelous archi- tecture which we shall find when we come to consider the living structures, in a chapter devoted entirely to that subject. CHAPTER 4. THE LIVING STRUCTURES. The crust of the earth discloses to us like the leaves in a book an enormous number of animals and plants that have lived in the past but are now extinct and no more. Every layer and stratum is a page in the history of the life that has existed on this planet in the past. Just what was the cause of failure and its extermination in some cases is not easy to tell. However in the evolution of living structures, it is the same as in the evolution of other structures and those produced by man, the best will be re- tained and the inferior rejected. The discovery by some animals of how to make feathers with which to cover their bodies and wings with which to fly, was a great invention and improvement, which caused a great change in the flying animals. The living struc- tures that have existed in the past show the same gradual evolution and improvement by new inventions and dis- coveries as the evolution of man from his savage state up to the present time. Mr. Haeckel states, ''Cells are grouped together un- der the idea of sculptors or builders because they alone in reality build the organisms." As to this fact, I agree with him, but I do not agree with him when he states that the cause of the building is only a chemical and mechanical force, and that it all THE LIVING STRUCTURES 109 comes about by chance. The inorganic forces like elec- tricity, heat, etc. do not produce anything for a purpose nor do rocks and dead matter produce machines or houses. Mr. Haeckel states: *'We notice the very re- markable fact that the egg cell in its original condition is so exactly the same in man as in all other animals that it is impossible to discover any essential difference." He gives the follow^ing figure 9 to illustrate this, and then he goes on and gives a description of the cell to show what a perfect and complete animal he is. He says : "In order to be thoroughly convinced that every cell is an independent organism, it is only necessary to trace the active phenomenon and development of one of these tiny bodies. We then see that it performs all the essential life functions which the entire organism accomplishes. Every one of these little beings grows and feeds itself in- dependently. It assimilates juices from without, absorb- ing them from the surrounding fluid. The naked cells can even take up solid particles at any point of their sur- face and therefore eat without using any mouth or stom- ach. Each separate cell is also able to reproduce itself and to increase. This increase generally takes place by simple division. The nucleus parting first by a contrac- tion round its circumference into two parts, after which the protoplasm likewise separates into two divisions. The single cell is also able to move and creep about if it has room for free motion and if not prevented by a solid cov- ering. From its outer surface it sends out and draws back again finger like processes, thereby modifying its form. Finally the young cell has feeling and is more or less sen- sitive. It performs certain movements on the application of chemical and mechanical irritance. Thus we can trace in the single cell all the essential functions, the sum of which constitute the idea of life, feeling, motion, nutrition 110 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Fig. 9. — Primitive eggs of various animals, performing amoeboid movements (very much enlarged). All primitive eggs are naked cells, capable of change of form. Within the dark, finely granulated protoplasm (egg-yelk) lies a large vesicular kernel (the germ-vesicle), and in the latter is a nucleolus (germ-spot); in the nucleolus a germ-point (nucleolinus) is often visible.

THE LIVING STRUCTURES 111 and reproduction. All these properties, which the multi- cellular highly developed animal possesses, appear in each separate cell at least in youth. There is no longer any doubt about this fact and we may therefore regard it as the basis of our physiological idea of the elementary organisms." After this general description of the cells of the differ- ent parts of the body, he makes the following statement in reference to the brain cells : "In the protozoa in the one cell plants and primitive animals, the whole organism permanently consists only of a single cell. On the con- trary in most animals and plants, it is only in the earliest Fig. 10. — Three epithelial cells from the mucous membrane of the tongue. — Haeckel. period of individual existence that the organism is a sim- ple cell. It afterwards forms a cell society or more cor- rectly an organized cell state. The human body is not in reality a simple life unit as is at first the universally current simple belief of man. It is rather an extremely complex social community of innumerable microscopic organisms, a colony or a state consisting of countless in- dependent life units of different kinds of cells. * * .* All the numerous tissues of the animal body such as the en- tirely dissimilar tissues of the nerves, muscles, bones, outer skin, mucous skin and of other similar parts are originally composed of cells, and the same is true of all 112 CELL INTELLIGENCE THE CAUSE OF EVOLUTION the various tissues of the vegetable body. These cells, which we shall hereafter consider more closely, are inde- pendent living beings, the citizens of the state, which con- stitute the entire multicellular organisms. We thus have before us a highly complex apparatus, the more minute structure of which we have hardly begun to know, even with the help of our strongest microscope and the signifi- cance of which we rather guess than know. Its complex mechanism is capable of the most intricate psychical functions. But even this elementary organ of mental ac- tivity of which there are thousands in our brain, is only a single cell. Our whole intellectual life is but the sum of the results of the activity of all such nerve cells or mind cells." The living structures that we see include all those things containing life such as plants, trees, insects, ani- mals, birds, fish, etc. They are all produced by the cell. They are constantly changing, a fact which proves that the builders are all the time trying to improve their habi- tation in order to meet some climatic or other condition, or obtain some advantage in one way or another in the struggle for existence. By reason of this fact, the scien- tists have decided that it is impossible to classify them as animals and plants because they overlap each other so gradually that it is impossible to tell where the one be- gins and the other ends. We might classify them gen- erally as either movable or as stationary structures. The plant building cells usually build stationary structures be- cause they are able to make their own food and building material by the aid of sunlight from the raw material of earth, air and water. The animal building cells on the other hand being compelled to move about in search of food build movable structures. The classification would not in all cases be correct, as some plants have movable THE LIVING STRUCTURES 113 parts such as sensitive and insect catching plants. How- ever, as a general classification, it is as good as any to con- sider them as either stationary or movable habitations of the cell, just as a house is a stationary habitation of man while a ship is a movable one. Some of the simplest structures are mere associations or groups of cells like the micro gromia socialias. These cells understand how to. inclose themselves in shells, and stick the shells together, and in that way remain together in a social community. They have already discovered the art of building covers or armours about themselves of Fig. 11. — Blood-cells, which increase by divi- sion, from the embryo of a young stag. Each blood-cell has originally a kernel, and is globular (a). When they are about to increase, the cell- kernel, or nucleus, first separates into two kernels (b, c, d). The protoplasmic body then becomes pinched in at a point between the two kernels, which become mcfre widely separated from each other (e). Finally a complete sepa- ration between the two parts is effected at the Doint where tite original cell was pinched in, so that there are now two cells (f). — Haeckel. lime and other materials, and the advantage of associat- ing together for offensive and defensive purposes in the struggle for existence. Fig. 12 is a description of this ani- mal taken from a text book on zoology. This cell is similar to the cell heretofore considered under the name of volvox. Man in his first days of development is also a mere cluster of cells, the same as this. After the cluster is formed, then these arrange themselves into layers in the shape of a cup, which is the beginning of the stomach. A wonderful plant or animal, whatever a person may wish to call it, is the Physalia. It is also called the Portuguese 114 CELL INTELLIGENCE THE CAUSE OF EVOLUTION man-of-war. In a book on Zoology it is briefly described as follows : "One of the most remarkable and best known of this group. It consists of a pear shaped and elegantly crested air sac floating lightly upon the surface of the water and giving oflf from its under surface numerous long and var- ied appendages. These appendages are the different mem- bers of the community and perform different functions, — some eating for the whole, others producing medusi buds Fig. 12. — Microgromia socialis. A, entire colony; B, single zooid; C, has undergone binary fission, with one of the daughter-cells creeping out of the shell; D, flagellula; c. vac. contractile vacuole; nu. nucleus; sh. shell. and others being the locomotive members, the latter hav- ing tentacles with powerful stingers that stretch out be- hind the floating community. The air sac is three or four inches long." The social community of cells that build this structure called Portuguese man-of-war, show wonderful skill, as they are able to sink or swim at will. The Albatross Ex- pedition describes them as follows : "The slime on the sea weed for instance may have come from a most poison- ous jellyfish known as the Portuguese man-of-war, that THE LIVING STRUCTURES 115 .^77^, pn Fig. 13. — Physalia or Portuguese Man of War; the living animal floating on the surface of the sea. cr. crest; p. polype; pn. pneumatophore. has stung to death many valiant swimmers w^ith its ten foot streamers, that paralyze the body. On fair days these formidable creatures lift their pink and blue oval 116 CELL INTELLIGENCE THE CAUSE OF EVOLUTION crests above the surface, but in rough weather they sink and one of their streamers entangled in a tow net might do serious harm, as happens on the slime banks of Behr- ing Sea, where the cod fishermen suffer grievously when their lines come up smeared with a poisonous jelly fish excretion. It was the 'Albatross' that traced the cause of this Behring Sea fishing trouble to a jelly fish." We see that this colony of cells can sink when necessary to evade the crushing force of the waves and again float when the weather and conditions are favorable. This ani- mal looks like the ordinary sea weed floating on the water but upon a closer investigation we find that this is more than a mere social gathering of the cells. Here they have discovered the advantage of specialization ; each bunch of cells takes charge of its particular line of work, such as moving about, reproduction, capturing and devouring smaller individuals for food. You notice that they have also discovered a method by which they kill and capture other animals for food by a powerful sting. It is not likely that they can see or hear in the sense that we under- stand that power. They can, however, feel, smell and taste. The thinking capacity of the cells that make up this social community must be the best, when we consider the discoveries and inventions they have perfected in the course of their development from the single cell .to the present state. Consider the million of individuals in- volved and occupied with their different kinds of work, in the make up of this social community. This colony of cells we call Physalia or Portuguese man-of-war is called an individual. We might next consider the Star Fish. It has one eye ; and has feet with sucker ends so that it is able to walk almost anywhere and in any direction. It has developed a very good smelling apparatus and is very well equipped THE LIVING STRUCTURES 117 for life. It is encased in a star shaped structure, strong and tough as bone and its star shape makes it a disagree- able substance to swallow by any larger animal. The cells that build this structure have been able to hold their own in the struggle for existence and they have reason to be proud of the progress they have made in the past ages. We might consider next the species of sea plant or ani- FiG. 14.— Starfish. feet. General view of the ventral surface, showing the tube- mal called the antedon. This animal fastens itself on the sea bottom. It starts to grow in the same manner as any other animal. The single individual cell who starts the building of this animal, first swims about in the ocean, then finally settles down and builds this structure. The secret of the success and progress of this individual is in the fact that "it covers itself with such disagreeable build- ing material that other animals will have nothing to do with it and cannot use it as food. This animal has been 118 CELL INTELLIGENCE THE CAUSE OF EVOLUTION able to produce electric lights in different places of its body, as you will notice from the following by the Alba- tross Expedition : "In the midst of gorgeous submarine forests and waving gardens that fringe the reefs of the ocean floor and spread over its vast plains are abundant clusters of shining trees or bushes, known as sea feathers or sea pens, these also being animals, not vegetables. Fig. is.— a ntedou. Side view of entire animal. Their long stems glow with a dull phosphorescent light when the trowl nets bring them up from the depths, and if they are touched with ammonia they shine brightly. It is thought that the light is dulled through their fright in capture and it is probable that normally they give forth a brilliant radiance when they desire to attract their prey or to terrify their enemies. * * * Never was there an animal so Jacking in any immediate usefulness as the THE LIVING STRUCTURES 119 Crinoid. It cannot move, it has no eyes ; it makes no at- tack ; it does no harm. It simply eats, playing the part of universal scavenger of the seas, catching all foods that fall through the v^aters, animal and vegetable, in its ten or more waving arms, each of which has a long groove lined with propulsive hairs that work the food along in the manner of a moving stairway to a central mouth and stomach. This stomach lies between the basis of the arms, which rest either upon a long stalk or upon two or three dozen legs, that cling fast to rocks or other animals or spread out upon the surface of the mud. The crinoid is perhaps the only creature in the sea that is not desired as food by some other creature, but these animal lilies, which eat everything, are not themselves to be eaten, be- ing too brittle, too full of lime, all skeleton, as it were. Even the stomach of a crinoid has its own skeleton." You will notice that this animal is just as much a plant as an animal. There is no difference in the beginning nor in the development of a plant or animal. It is put up for a purpose. If it is to be a stationary structure, it will look like a plant ; if it is to be a movable structure it will look like an animal. It all depends upon the purpose for which it is made. This animal, which grows like a plant in the bottom of the sea, is merely a house lit up with phos- phorescent lights wherein dwell millions of individual cells. We might next consider a very large group of struc- tures known as shell animals. The cells live in a social colony which is protected with a shell made of lime and other material. The shells that protect them are usually of such strength and thickness as would be required to withstand the pressure and force of the water at that par- ticular place, or the animals that may attack them. They are simply movable houses wherein live vast colonies of 120 CELL INTELLIGENCE THE CAUSE OF EVOLUTION cells. These cell colonies are generally specialized in their work, as some attend to locomotion, some to diges- tion, etc. Many have also developed special sense organs like eyes and ears. They are all well adapted to their Fic. 16. — Shell of Triton nodijcrus. place and condition in life and they live secure and com- fortable in their strong and beautiful habitations. We might next consider the individual known as the cuttle fish and he is a wonder. The cuttle fish is covered with a hard shell made of carbonate of lime arid other THE LIVING STRUCTURES 121 hard material. Its size is up to three feet in length, so it is small enough to have a number of enemies. It is pro- FiG. 17. — Sepia cultrata or cuttle -psh. Entire animal viewed from the dorsal aspect. vided with a sack of black material like ink, which it throws into the water behind it when pursued by ene- mies and in this way it escapes very easily. It has long 122 CELL INTELLIGENCE THE CAUSE OF EVOLUTION tentacles provided with pow^erful suckers, v^hich hang on to any animal that touches them. It does not look like an animal, and for that reason it is able to get near fish and other animals on which it feeds. The scheme of throwing ink in the face of its pursuers is not the only wonderful invention of the cells that build this individual. The most wonderful is its power to change its color at will. If its surroundings are green, it will change from black to green, etc. How is it able to do this? It has been demonstrated that the cells in the skin get a picture of the outside surroundings through the eye, that the skin cells have several color shades on hand and that they stick those tints up to the surface of the skin, which will produce the shade desired. It shows how the cells in the individual communicate and work with each other. The skin cells get a picture of the outside from the brain cells, who must first get it through the eye. If you injure his eye or the nerve leading to the eye, he is not able to change his color. This invention of changing his color at will so as to be able to escape enemies or get closer to its victim is certainly wonderful. How long the cells struggled with the elements and enemies before they discovered and perfected these inventions to aid them in the battle of life we can only guess ; but from the time it first discovered the advantages of working together in a social community until it perfected the eye, next the ink scheme and the power to change color, it must have been ages. The eye must have been perfected first, or else it could not know the effect of roiling the water with ink, or of changing its ccHor to correspond to surroundings. We might consider now this wonderful structure known as the torpedo ray, or sting ray, as it is sometimes called. This is a fish that kills its victims with an elec- tric shock. Here is a colony of cells that have built a THE LIVING STRUCTURES 123 habitation with which to move through the water like a fish and have also built up in it electric storage batteries, ^■v I Fig. 18.— a Torpedo-Ray with the electric organs dissected out.

Think of all the experimenting that must have 124 CELL INTELLIGENCE THE CAUSE OF EVOLUTION been carried on, until they perfected a machine with which to gather electricity from the surroundings and keep it stored in batteries ready for use. It could not have been of any advantage or use until they had it per- fected and all the machinery working. Until that time they must have had a committee of cells continually working on the idea. They could not have commenced experimenting until they had previously discovered the effect of the electric shock and could see the idea of using and developing it into a weapon for oflfensive and defens- ive purposes. pcfj Fig. \9.— Osfracion (Coffer-fish), br. ap. branchial aperture; d. f. dorsal fin; pet. f. pectoral fin; v. f. ventral fin. Then we have the coffer fish. This individual is a per- fect box made of some horn like material in nearly the shape of a fish. The box has an opening for just the nec- essary steering and propelling apparatus and the eyes and mouth. It is protected with a color conforming to its surroundings but it cannot change its color. It is a wonderful submarine boat, well protected with armor and so constructed that a larger fish wi/1 not eat it unless THE LIVING STRUCTURES 125 very hungry, as its spikes make it a very disagreeable morsel to swallow^. The strong covering and protective color give it such advantages that it has been able to hold its own with others in the struggle for existence in the past, and is with us today and not numbered among the extinct species. Another most wonderful individual is known as the Stomiasboa or lantern fish. This fish is black with phos- phorescent shining light in front, and two rows of bull's Fig. 20 — Stomias boa or Lantern Fish. The white dots are the luminous organs. eye lanterns the whole length of the underside of his body. These spots all shine like little electric lights and the black form of the fish cannot be seen in the night, but only his spots, which also light up his surroundings, so that he can see his victims with his extraordinarily de- veloped eyes adapted to see in the. dark. He is covered with a powerful scale, adapted to resist the pressure of the water two miles deep in the ocean, where he stays in the day time and where his enemies, the larger fish, can not follow him. Think of the wonderful skill exhibited in the construction of this individual, — his powerful eyes and mouth, with his powerful search light at the end of 126 CELL INTELLIGENCE THE CAUSE OF EVOLUTION his nose enabling him to see in the dark. These things are all necessary to an existence two miles down in the water. This perfect arrangement of everything to meet condi- tions, exhibited in this individual, must have also re- quired ages of experimenting by the best intellects. The Albatross Expedition describes him as follows : "Among the strangest of these ascending night feeders are the lantern fish, remarkable for this, that their bodies are dotted over with electric lights ; certain round phos- phorescent spots arranged in rows along the sides, that glow brilliantly just as fire flies glow, especially a large spot on the end of their noses that shines like a search light. So these queer fish move through the water, ascending and descending — small submarines all ablaze. There may be a double usefulness in these phosphorescent lights which flare up suddenly against a deep sea enemy and frighten him away, or which lure the prey at higher levels, as a candle lures the moth." It must be conceded that to be able to build and main- tain a submarine like this we call the lantern fish, which can light up its surroundings and adjust the structure to resist the pressure of the water at different depths up to two miles, is a task requiring the best engineering and keenest intellect. Think of the details to be looked after to keep it adjusted to the ever changing environment, to keep all the lights going, to gather the material and manu- facture the light. Fig. 21, the Lure Fish, is another illustration of a fish that tempts its prey by means of a phosphorescent light. He has a bait that shines, attached to the other end of the string which he lets out like a fishline to attract curious individuals. The string to which his bait is attached is such that he can let it out and pull it in at will. This you THE LIVING STKICTUIIES 127 will see is a moving habitation something like a sub- marine v^ith a fishing apparatus attached. We never stop to consider the position occupied by the individual cells that build animals and plants, who must conceive and execute ideas. While this submarine like J Fig. 21. — Line Fish. individual was lying in wait for his victim, it must have occurred to the cells occupying and in charge of it that animals are attracted by a light. That if they could fix up a shining bait, which they could let out a short dis- tance to attract attention, they could hide their sub- marine and decoy their victims within reach of their grap- 128 CELL INTELLIGENCE THE CAUSE OF EVOLUTION pling apparatus, called the mouth, arranged in front of the individual. From this idea conceived, they would pro- ceed to build this fishing apparatus. This is what the Al- bastross Expedition has to say about him : "The potency of light in attracting wanderers of the deep is seen in the equipment of the Lure fish, a gro- tesque creature with a huge mouth that hides its black body in the mud, and waits patiently for victims, dan- gling before them a phosphoresent bulb that shines at the end of a long filament — a self-grown and self-baiting fishing rod, curving forward from the animal's head and hanging temptingly before its hungry jaws, ready to snap open at the approach of a curious visitor. These Lure fish are found at the depth of three miles or more." Mr. Mufiit gives the following interesting description of a few of the enormous number of different kinds of individuals found in the ocean : ''Another danger lurking in the tow nets is the possible presence of a strange crustacean, related to a crab, an uncanny creature about three inches long that is invis- ible, literally invisible, owing to the fact that its head and body, its arms, legs and claws are quite transparent. The presence of this animal in the receiving pan is usu- ally indicated by a disturbance among its visible neigh- bors, the shrimps and fishes, and when it is lifted out with a pair of tongs it appears like the glass model of a crab with slowly moving glass legs and glass claws. When killed this crab loses its transparency and reveals itself in a dull white coloring like the white of an egg. The 'Albatross' encountered many of these invisible wrigglers while fishing in Japanese waters. It is well known that very young fish and tiny eels are quite transparent except for two black dots, which mark their eyes. "Each haul of nets brings up some deep sea wonder. THE LIVING STRUCTURES 129 It may be the hideous viper fish with teeth so long that they fold outside of his mouth like the tusks of a wild boar, or the snipe eel with its bill like its name sake and a body like a length of whip cord or the queer pelican fish that will swallow a fish much larger than itself and somehow digest it, or a dead ribbon fish with its almost transparent body, 20 feet long and a foot wide and half an inch thick, or a great red jelly fish full of poisonous darts coiled up in its body, and ready to shoot out their venom against any touch. In New England and arctic waters some of these jelly fish grow to enormous size ; their bodies measuring six or eight feet across and their pendent streamers reaching down seventy feet or more. I may mention also the giant squid or cuttle fish thirty feet long, a whitish colored beast' that is always found dead, the same being true of the giant octopus with its reach of seventy feet from tip to tip of its huge arms. "The jewel beauties, swimming about rather tamely would be helpless against the ravenous pursuers were it not that they live in shallow tide pools, and near coral reefs where these pursuers dare not follow them. Why not? Because coral reefs are full of stings of the live coral creatures, stings that hurt a man's hand if he touches them and might destroy the eyes of any big fish that ventured among them. And tide pools abound in sea urchins with sharp barbed spines, hundreds of them that break off inside the wound." The fierce struggle for existence that has been going on in the sea for ages has produced these wonderful individuals, in the same man- ner that the struggle for place and power that is now going on in the war between the English and the Ger- mans is causing inventions of many kinds, and weapons and engines of destruction of different char- acters. We must keep in mind that the builders of all 130 CELL INTELLIGENCE THE CAUSE OF EVOLUTION these individuals are the cells, just as the builders of all the different structures now used in war in their struggle for national existence, are the human individuals. The structures produced by cells or cell communities are all on the plan intended to resist attacks by hungry enemies ; take, for instance, the common turtle with its armor plate of bone, which in every way resembles a fortification. Millions of living beings working together live inside of this moving fort we call the turtle. Fig. 22. — Skeleton of Turtle. Glyptodon clavipcs. What difference can there be in the intelligence or skill required in building a submarine by human beings and the building of a fish by the cells? In every case there must be a preconceived plan, a purpose to capture and escape, to do this or that. They are made with an end and purpose in view. The time will evidently come when every important battle will be fought either in the air or under water. The submarine now must have eyes in order to see where to go and so as not to run into nets! Inside are the individuals who run it and take care of it THE LIVING STRUCTURES 131 precisely in the same manner that the cells run and take care of the individual they inhabit, be it animal or plant. Think of that invisible crab! How are the cells able to build themselves into a structure so as to be transparent? Those are secrets for us to solve. Fig. 23. — A submarine made by the cell. I must not forget the African fish that constructs a moisture proof house in the mud where it sleeps for six months, during the dry season, living on its own fat gathered during its activity. It is described as follows : "A remarkable fish known as protopterus annectens is found throughout the whole of tropical Africa, but is most common near the West coast, where it sometimes attains a length of six feet. During the dry season, when many of the ponds dry up, the fish descends some dis- tance into the mud and forms a rounded hollow for a 132 CELL INTELLIGENCE THE CAUSE OF EVOLUTION THE LIVING STRUCTURES 133 nest, which is lined by a capsule of hardened mucus secreted by the glands of the skin. It hibernates thus for nearly six months, drawing its sustenance from the fat secreted when it is active." This fish is wonderful in that it is able to make a nest in the mud, where it will not lose any of its moisture, by lining its room with a secretion which will prevent the escape of the moisture. During its activity the cells in charge of this individual gather and store away enough food in the way of fat so they can live and enjoy life until the rainy season comes again and provides the water to float them. The ability of animals to store away food to be used at a future time is a common habit, that is, with all animals that sleep in the winter, like badgers, bears, etc. The cells in the body gather and store food for the purpose of tiding over a time when food will be scarce and hard to get. What possible difference can there be in the intelligent purpose evidenced by the cell in providing for the future, and the animal and man doing the same thing? There can cer- tainly be none whatever. Take again for instance protective coloration. The military experts are now adopting and taking advantage of the tricks of the cell. The zebra in its bright stripes is almost invisible in the jungles of his natural habitat. When the cells building the zebra gave him the stripes which make him so conspicuous in the circus they knew what they were doing. The experience of hunters all testify to the fact that the tall grasses and trees in the jungle where he lives make the zebra almost invisible. In reference to the cause of the color of animals, plants and fish we have now fully demonstrated that it is caused by the action of cells occupying the individuals, especially if they have eyes with which to take a picture of .the out- side surroundings, and transfer this to the skin cells, who 134 CELL INTELLIGENCE THE CAUSE OF EVOLUTION are in charge of the color business. The following is a very interesting article on this matter, altho it has been demonstrated several times before, and in one case the Fig. 25.— Zebra. fish was able to produce a checker-board on his back when the bottom of his aquarium was painted in that way. S. O. Mast of Johns Hopkins University has pub- lished in the ''Proceedings" of the National Academy of THE LIVING STRUCTURES 135 Sciences, April, 1915, some results of observation and experiments made at the U. S. Biological Station at Beau- fort, N. C. The work is to be published in full in the bul- letin of the U. S. Bureau of Fisheries. He says : "Nearly all fishes simulate their environment to some extent and some flounders do so with remarkable accur- acy and rapidity. It was found that flounders in glass dishes became nearly white on a white ground and nearly black on a black ground. They also assumed approx- imately the colors of all grounds, except red. Fine and coarse patterns in the ground produced correspondingly fine and coarse patterns in the skin, but there was no actual reproduction of patterns. Five days' sojourn in a black pan was required to produce a maximum blackness in a flounder that had been kept two weeks in a white pan, but the change from white to black was effected in two minutes in the same flounder after it had been trans- ferred from one pan to the other. The change from black to white always required an hour or more. Color changes are comparatively slow. Yellow usually predominates in the environment and is assumed more rapidly than green or blue. "The skin of flounders contains black and yellow cells callejd chromatophores and opaque white cells called iridoeytes. The changes in color and pattern are pro- duced by changes in the arrangement of the colored cells and in the extent to which they are hidden by the white cells. These changes are regulated by ocular impressions. Flounders become uniformly white when the head-end is placed on white and the tail-end on black. They be- come black when the head is on black and the tail on white and they become gray when one eye is on white and the other on black. Exposure of one eye to a fine and the other to a coarse pattern produces a combination 136 CELL INTELLIGENCE THE CAUSE OF EVOLUTION of a fine and coarse pattern in the skin. The influence of each eye extends over the entire body. The skin becomes yellow when a yellow card is placed very near the head. A flounder deprived of one eye simulates the background quite normally, but there is no simulation whatever when both eyes are removed. Flounders fail to simulate the ground in very strong illumination from above and they become white on all ground when their eyes receive no light directly from above. Adaptation to the ground is not effected by covering the skin with sand, so that the fish cannot see it. Vision in fishes is very like human vision in regard to shade and color, but less acute in regard to size. Flounders distinguish between dots of two millimeters and three millimeters and recognize dots of one millimeter, but not those of five-tenths millimeters. By means of a rotating background of black and white sectors the acuteness of vision in regard to motion was found equal to that of man. Flounders adapted to a given color seek ground of that color, and color in the skin is produced only by exposure to the same color." It is a singular thing that scientists and the human mind by reason of vanity or for some reason will not conceive, or are not able to see that the minds that direct these very difficult acts of effecting these protective colors in fishes and animals are the cell minds and cell intellects. They build the fish and take care of it for their own selfish purpose. They alone are responsible for its success. These are facts we do not have to guess at. We do not have to spin any theory about it because we can see it. In a daily paper I read the following in regard to the acts of man and animals in reference to this same trait of taking advantage of protective color: *'If man has learned clever tricks for deceiving his enemy he has been taught by nature. In all nature there is scarcely an animal which THE LIVING STRUCTURES 137 is not characteristically marked for deceiving his enemy. Many butterflies are veined and marked like leaves and flowers with such splendid accuracy that when they are hidden in the petals of the flowers or hovering on the foliage they are not to be distinguished. Likewise the walking stick insect when it crouches among the green leaves cannot be differentiated from the twigs. Bird hunters are aware that it is difficult to discover grouse and partridges because of their bark-like coloring. Nature is so cautious in trying to protect many of her children against their enemies that she often changes their colors with the seasons. Most of the arctic animals change from brown to white as the winter approaches. This is no less true of many kinds of fish. Some have the facilities for harmonizing colors with the particular char- acter of bottom upon which they happen to be resting at the moment. The lesson of nature has not been lost upon man. From time immemorial bird hunters have clad themselves in green, that the animals would not distinguish them from the foliage and the surroundings. The American soldiers were the first to adopt the khaki uniform, because it is the color of the earth. European armies have now acted on our suggestion, although it has taken a long time to teach the French soldiers that the bright red on their uniforms is a menace, not an aid. Just at present news dispatches tell of the increased number of changes in the army uniforms in an effort to make the soldier invisible — or as nearly so as the ingenu- ity of man can make them. Russian artillerymen and scouts have been clad in long white cloaks and caps while fighting in the snow fields of the Carpathians. It is said that the adoption of nature's methods of pro- tecting animals has been so successful that it is impos- 138 CELL INTELLIGENCE THE CAUSE OF EVOLUTION sible to distinguish moving men from w^aving shrubbery when but a few yards distant. Practically every army involved — and they include many nationalities and many picturesque styles of uni- form practically unheard of on this side of the Atlantic — is adopting this method of uniforming, to some extent. You see that these acts of man and animals, which we consider very intelligent when performed by man as an individual, we refuse to consider intelligent when per- formed by animals or more correctly speaking by the ani- mals we call cells, who build the animals and perform the work. There is a moth called, "The Death's Head Moth," because it has the resemblance of a skull and cross-bones on its head, which is merely an arrangement as a pro- tective color. A scientific magazine makes the following remarks about it: "The Death's Head Moth not only has a mouth with which to eat, but it can make a noise which resembles that of a mouse. It is the only moth which makes any sound. It is this peculiar sound which it makes, as well as its resemblance to a skull and cross- bones marked upon its head, which makes superstitious people afraid of it, for they believe that it brings them trouble. The moth though forbidding in appearance is entirely harmless, of course." Now who are the most intelligent beings, the brain cells directing the action of the man afraid of this moth, or the cells that build and direct the moth? Which of the two are the most profound thinkers? It would seem that the cells in tjie moth discovered the superstitious nature of man and adopted this style of protective color to frighten him. In reference to the intelligence of insect-building cells of all kinds many of which are also able to change their THE LIVING STRUCTURES I39 color at will, space will not permit going into details. In their place in life, the struggle for existence is fierce and competition very strong, and they have also discovered nearly every trick and method used by fishes and animals. The following article by A. L. Hodges states the situ- ation in a general way: "Few people are familiar with the fact that the diving bell was invented by a spider. Such however is the case and if it was not actually in- vented by him it was certainly used by him long before our hydraulic engineers made one for the same purpose. The diving bell is, as is well known, a cup-shaped body with open end down which is let into the water. The air is caught in the bell and keeps the water from rising beyond a certain level at any specified depth and of course allowing anyone inside to breathe and act as if he were on the ground. The new improvement of the diving bell, known as the Caisson, is a huge pipe which has compart- ments into which the air is pumped from above. The spider's bell is filled more in this manner than in the other. **The name given to these little spiders is very appro- priate— Naiads of the family of Arachnida. The Naiad will build a little house of water-proof silk, held fast by strands fixed to neighboring blades of grass and stones, several feet under water. He completes the entire struc- ture before filling it with air — as if he knew that the air would tend to make it rise to the top and thus hinder the attaching of the anchors. *'But the method of getting air into their houses is per- haps the most peculiar and interesting of all instinctive acts of animals. Their abdomens are so made that a bubble of air can be caught underneath them. This the Naiad does, and swims to his house with it and turns it loose in the airy structure. The process is repeated sev- 140 CELL INTELLIGENCE THE CAUSE OF EVOLUTION eral times until the little house is full of air. Of course the open end of this house is down and this has to act also as the entrance to it. In the little water-house the spider spends the winter and rears its young ones. The house also acts as a lair from which the spider can jump on un- suspecting prey. "Another peculiar thing about the Naiads is that they never get wet. They have thousands of small hairs on their bodies which hold and keep the air from being washed off when they enter water and so the air sticks and water cannot approach. Scientists are acquainted with many other insect engi- neers, but with none that approach Naiads in intelligence and skill. The Water Beetle is probably the only other one in their class. It builds a water-proof nest under water, but does not live in it. It merely lays its eggs in the nest, seals it up and leaves. The Mason Bee is as his name implies a builder of structures of stone and mortar. The nest is attached to almost any solid structure and actually does consist of small stone, cemented together with mortar. The house consists of many cells of oval shape, and into each an egg is laid. The cell is lined with silken web by the mother who gets out of it by holding its top. Before leaving, however, she hermetically seals up the cell and leaves the youngster to its fate. "However, such are the arrangements of nature. As soon as he gets to feeling his oats and consumes the food left him by the mother he finds himself supplied with tools hard and sharp enough to cut through the walls to freedom. "A member of this family found in England makes his own bricks, selecting brown clay for the purpose, which he mixes with saliva, rolls into small balls which soon THE LIVING STRUCTURES 141 become hard and then cements them together. These pellets are as large as small peas and one bee has been known to prepare as many as one hundred and fifty in a single day." I have watched the action of bees, beetles, spiders and ants and other insects and must say that their actions show intelligence of a very high degree and will refer to many of their acts later on, which are simply wonderful. You might say if the insect building cells are so intelli- gent, why do they not build larger and stronger struc- tures like ourselves or other animals. Upon that point we need but consider all the structures produced in the past ages, like the Mastodon and thousands of others that went too far in that direction and got the structures too large. Their skeletons are now conclusive evidence to the insects and ourselves that size is not necessarily a quality that spells success. The size must be considered in the light of permanent and perpetual existence on this planet, as well as the other features. I quote the follow- ing from the Scientific American, which is very signifi- cant : "Rarely is it safe to speak of anything as ultimate in prehistoric life, but there is little doubt that the American Museum now exhibits a skeleton of the largest flesh-eating animal that has ever lived. This is Tyran- nosaurus, the tyrant lizard, a dinosaur that lived during the close of the Cretaceous period. It was one of the very last expressions of its race and, judged by size and struc- ture, was king of its kind. An idea of its immense size can be formed from measurements of the skeleton, 47 feet in length, and, as mounted, 18^^ feet in height. When fully erect this animal would have reached a height of 20 feet. "Larger herb-eating dinosaurs have been found in America and East Africa in older rocks of Jurassic or 142 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Fig. 26. — Skeleton of Tyrannosaurus Rex No. 5027, 47 feet long and 18 '.'2 feet high. — Scientific American. early Cretaceous age, but the flesh-eaters contemporan- eous with them were a third smaller than the present animal. -'The Tyrannosaurus was capable of destroying any of THE LIVING STRUCTURES 143 the contemporary creatures and was easily king of the period and monarch of its race." Now if it is true that the cell is a builder of all living things, both plants and animals, we should be able to find the same intelligent scheme for self-protection and seU-perpetuation also in plants, or what we might call their stationary habitations or structures ; and such is the case, for the schemes and tricks employed by plants to serve their purpose show intelligence of a high order. It is impossible in this short chapter to go into the details and describe the innumerable methods used by plants to fight drought, animals, frost, heat, etc., but the following article from the Literary Digest is a very good general description of some of the methods. The article intends to describe some of the unnecessary cruelties practised by some plants on animals and insects in order to further their own selfish purpose. It says : "Take the case of the fruit of the Martynia, a South American plant, which is armed with terrific hooks, sometimes as much as five or six inches long, so curved that they seize hold of passing animals and plunge deeply into the flesh. It is said that the Bullocks are often thus driven half frantic and suffer dreadful wounds. Of course the final result is that the seeds receive a very wide distribution, but a large amount of needless suffering seems to be involved ' Even more astonishing is the case of the Grapple Fruit of South Africa (Harpagophytun). This species is of a low growing habit and bears fruits which are freely adorned with most formidable barbed appendages. The fruit secures its dispersion in the following manner: in its position out of the ground it is liable to be trodden on by sheep, deer, etc. ; at once, of course the hooks catch hold and these penetrate into the tender places of the foot between the horny portions. The unhappy animals limp 144 CELL INTELLIGENCE THE CAUSE OF EVOLUTION - D 5 ^^ C '-> x^ "'S 2 S c •i'ti t> c '^ .

During this time the most dreadful wounds are produced and as well the creature is very likely to fall a victim to some beast of prey. In this con- nection a very singular happening sometimes occurs which is well authenticated ; viz., a lion captures an ante- lope with a grapple root on his foot ; when making his meal, the lion gets the hook capsule in his jaws and the barbs speedily become entangled in the mouth parts. The more the lion fidgets the less likely is he to get rid of the encumbrance, but owing to the pain and annoyance the beast cannot leave his mouth alone, so the miserable business goes on. Days pass and the lion is quite unable to eat and as a consequence becomes weak and helpless. So the king of beasts dies, killed by the fruit of the Grap- ple plant. It is of course recognized that plants must take certain means to protect themselves against the attacks of animals. Some of the measures which have been adopted are positively vindictive. Take the case of the common stinging nettle. Here the plant is covered with minute hairs which penetrate the skin and at the same time in- ject an irritant poison, the effect of which lasts for hours. Some of the tropical nettles are much more terrible. The following is an account taken from the Himalyan Journal of Sir Joseph Hooker in which an Indian Nettle is de- scribed: "This plant, called 'Mealum-Ma,' attains fif- teen feet in height. It has broad glossy leaves and though apparently without stings is held in such a great dread that I had difficulty in getting men to help cut it down. No wonder that the plant is avoided, for if a person is stung by the microscopic hairs the results are appalling. The pain is at first comparatively slight, but after a few hours the effected part feels as if it were being rubbed 146 CELL INTELLIGENCE THE CAUSE OF EVOLUTION with a hot iron. Later the most distressing symptoms arise in other parts of the body, which not uncommonly involve the contraction of the muscles of the jaw and other indications which are similar to those to be ob- served in the case of lock-jaw. In one instance it was nine days before the unhappy individual was free from pain and discomfort. In such a case as this it would seem that a huge amount of unnecessary suffering is in- volved. It is possible to protect a plant from attack as can be seen in many cases without adopting such brutal methods. "Self-defense has been carried to a fine art among desert plants, especially the cacti. An array of spines is of course an admirable means of preventing an attack, but many species have carried the matter a good deal further. In some kinds of prickly pear they have minute barbs on their spines and if any animal should even brush up against them the spines hold on firmly when driven into the flesh. They are loosely attached so that the un- happy creature takes away a large number of spines when he withdraws. These remain to produce festering wounds. Another cactus which adds singular hooked spines to the straight variety is called "The Wait-a-bit Plant." The hook holds the clothes or flesh and mean- while the sharp straight spines do deadly work. "It is of course well known that a certain number of species find it needful to capture insects in order that they may supplement their supply of nitrogenous food. In most of the schemes the unhappy victim is doomed to undergo the torture of a lingering death. Very rarely is the insect killed at once. First of all let us consider the case of the Darlingtonia, a plant which usually catches winged insects. The flies are lured by honey secretion to enter the hooded process at the top of the pitcher-like THE LIVING STRUCTURES 147 leaf. This they do by means of an opening on the under- side. The whole of the upper portion of the hood is cov- ered v^ith transparent patches like so many v^rindows. Now^ when the fly wishes to leave he naturally flies up- ward toward the light which streams down through these windows. The real opening is hidden in the shade of the under part and passes unnoticed. Thus the flies simply beat themselves to death in a vain endeavor to escape through the transparent places. This proceeding may extend over hours, but it always has one ending. The fly falls exhausted into the fluid at the bottom of the pitcher and is drowned Many flies meet with peculiarly brutal death in connection with the Venus fly-trap. The insect is captured by its legs and held fast; meanwhile it beats its life away in vain endeavors to escape. In conclusion Mr. Bastin says : "The instances given above are only a few out of a Very large number which might be brought forward to show that in many ways plants are guilty of great cruelty. One cannot get away from the idea that most of the suffering involved appears to be quite unnecessary, for there are plenty of instances to show that the same ends can be achieved in less painful ways." This article was originally written by Mr. Bastin in the Scientific American to show some of the unnecessary cruelties practised by some plants on animals and in- sects in order to protect themselves or to spread their young. However, we have no cause of complaint against the plant for cruel and inhuman treatment, as we never stop to consider the pain or feelings of the plants to fur- ther our wishes, so why should the plant pay any atten- tion to ours? I never can forget my astonishment when I first met the drought and animal resisting structure called the "Spined Cactus" found growing on the Western 148 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Plains with spines so arranged that it would be impos- sible for the deer or buffalo to attack and eat it without suffering terrible torture. Lack of space will prevent a consideration of the birds, except to refer to them in a general way. The discovery of the art of making feathers as perfect as they are today, must have taken ages. Man was able to perfect a flying machine in a very short time, but he had the experience of the world at his feet to teach and help him. The wonderful skill exhibited by young birds in being able to fly the first time they make the attempt will be explained later. However, it is no more of a mys- FiG. 28. — Bird descending. (Made by cell.) tery than the ability of the aeroplane to fly in its first at- tempt. It is no more difficult to operate a machine than to build it. If the cells understand how to build the aerial structure with which they are able to navigate the air it seems queer that they should not also understand how to operate it. That question will be more fully discussed under the chapter on cause of instinctive action of all kinds, which so far has seemed to be a mystery to man- kind. I can see no mystery in the instinctive acts of ani- mals or plants. The builder should know, and does know how to use the machinery he has put together. The living structures which are made by living beings, the cells, are all made for a purpose. For example, the long tongues of woodpeckers and humming birds with which they reach into deep crevices and holes, the web between the toes of THE LIVING STRUCTURES 149 the swimming animals and birds, and the long neck of the giraffe with which he reaches up to the high branches of the trees on which he feeds are structures that arise out of the desires and needs of the builders. Take for in- stance hair, this is a covering mainly to keep the body at an equal temperature. In a cold climate the covering Fig. 29. — Bird descending. (Made by man.) must be provided either by the cells in the body or by the acts of the individual himself, as in the case of man. The cells of a man do not make hair on the body, after having discovered a better way of covering the same with the skins of animals or otherwise, which covering can be re- moved when not required. Hair is produced as it is de- sired and necessary. On the animals farthest south the 150 CELL INTELLIGENCE THE CAUSE OF EVOLUTION hair is the thinnest and on those farthest north it is the thickest, but the evolutionist steps in and states that this is due to natural selection and survival of the fittest, — that is to say, those animals in the north that happen to be born with short hair w^ill be exterminated by the cold weather, and in that way all the short haired animals would be weeded out and only the long haired animals would be left to perpetuate themselves, and that is why we find long haired animals in the north. This proposi- tion you see leaves the whole cause of long hair in the north, to chance and not to desire and intellect. Upon in- vestigation we find, however, that the evolutionist is up against it. You can take for instance, a bunch of pups born in Iowa ; keep two in the house all v/inter, send two to New Orleans and two to Alaska and let two run out- doors and this experiment I believe will settle the whole question. You bring the pups together again in the spring in Iowa and you will be astonished at the dififer- ence in the length and thickness of the hair on the dogs. There has been no time to produce the extra length of hair by chance, natural selection or survival of the fittest. Where the climate required the long and thick fur the builders and caretakers of the body provided the cover- ing. The same is true of horses, cattle, cats and other animals. The hair will be short and thin on the animals sent south, and thick and long on those sent north. Everyone knows what long, thick hair the cattle and horses have that have been running out all winter in open sheds, among corn stalks and straw stacks. The necessity of protecting the body from destruction by the cold weather requires long and thick hair. The cells of the surface of the body understand how to get the material with which to build the protective covering, and they in- crease its thickness and length for that purpose when THE LIVING STRUCTURES 151 necessary and not otherwise. The actions of the cells in building hair are brought about precisely in the same manner as the actions of man in making and covering himself w^ith heavy clothing w^henever it is necessary and not otherwise. It is his needs and desires and require- ments that spur him to action. It is of course true that any person in a cold climate who does not have sense enough to make and cover himself with clothes will per- ish and be exterminated and this would be true of those animal building cells. The builders of every animal have sense and intelligence enough to increase the length and thickness of the hair if necessary in the same manner that man has, to provide himself with the clothes required. The act requires skill and intelligence sufficient to gather the material and build the structure, be it hair or clothes. One requires just as much intelligence as the other. There is a production of hair for a purpose, just as there is a production of clothes for a purpose, just so we find structures of all kinds produced in the living world for a purpose, as for instance, the shells of the sea animals; some are thick and powerful in order to resist the crush of the water pressure in the deep ocean, or the crash and hammering of the waves on the shore; other shells are thin like those which move over the mud in shallow still water. The shells are the houses in which colonies of cells live. Experience shows that if you plant them in deeper and rougher waters they will build a shell stronger and thicker, just as you might expect, for if the builders act with intelligence in one place they will also do so in other places. This fact has been shown in thousands of ways ; for instance, one class of cells will take charge of the work of another class, the cells in charge of the mucus mem- brane will build an outside skin covering if necessary, or the cells in charge of the outside skin will refuse to build 152 CELL INTELLIGENCE THE CAUSE OF EVOLUTION it if it is not the right thing to do. On this point Spencer makes the remark : "That is to say^ these literally outer layers of skin are capable of rapidly assuming one an- other's structures and functions when subject to one an- other's conditions. Mucus surfaces normally kept covered, become skin-like if exposed to the air, originally moist, tender to the touch and irritated by the air. The surface gradually becomes covered v^ith a thick, dry cuticle and scarcely more sensitive." The facts seem to be that noth- ing is produced or changed except w^hen it is necessary and for a purpose. It never takes place by chance. We find that differentiation will arise altogether from their method, place and condition of existence ; that every plant, insect, bird or animal is a structure designed to meet certain conditions of life, in the same manner ex- actly as a ship is designed to move over water, an automo- bile over the ground and the airship through the air. Plants and animals have so many structures in common, which over-lap each other in so many ways, that it is im- possible to tell in a great number of cases where the ani- mal commences and the plant ends. La Mark classified all creation according to the de- velopment of the brain and nervous system ; such a classi- fication proved later, of course, to be entirely erroneous, as it was discovered later that insects showed intelligence in their particular place in life equal if not superior to any of the higher animals. The cell that builds the little air- ship known as the lightning bug has the knowledge com- pletely mastered of how to produce a light without heat. Hundreds of thousands of dollars have been spent by the most skilled chemists to learn the secret known by the builders of this bug of how to produce a light without heat. We have finally, after spending considerable money THE LIVING STRUCTURES I53 in experimenting, learned from the silk worm how to make artificial silk. It is impossible to classify the living structures into classes or individuals in a great number of cases, as for instance, in the case of some sea-w^eeds or animals that grow fastened to the bottom of the sea. At first this crea- ture will be only a single cell, swimming in the water, then it will change and build itself into a fish-like form swim- ing in the ocean ; finally this form will change into a sta- tionary structure settled on the bottom of the sea like sponges or sea-weed. Every structure, plant or animal, shows clearly that it is made with a purpose of effecting certain ends and that is to satisfy some desire. Take the case for instance of the corn-plant. This plant in order to protect the cob from field mice and other rodents never starts a cob down near the ground. The starchy nutritious kernels embodying the embryo corn must be protected from weather, insects and birds, which is done by a very strong husk. This strong husk prevents the male germs of the plant who are located on top in the tassel from getting to the female germ in the kernel. How did they solve that problem and overcome that difficulty? By building a hollow tube from the female germ in the kernel extending clear out- side. When the male germ in the tassel falls down on the silk, which is a hollow tube, leading to the female germ he hunts up the end of the silk and crawls down through this hollow tube which directs him to the place of the female germ. Considered as a whole it is a won- derful scheme and all the difficult problems have been solved and taken care of in the best possible manner. In-breeding must be prevented if possible so the male cells are placed away as far as possible. There is a desire to give the young corn plant a start in life so each cell is 154 CELL INTELLIGENCE THE CAUSE OF EVOLUTION provided with food consisting of the starch of the kernel which is sufficient until they have been able to get them- selves established in the soil and by the aid of sunlight to make their own food and building material from the raw material at hand. The corn building cells work with a purpose in view arising from a desire to effect certain ends. We build houses, make clothes, produce food. We want and need these articles. We must be protected from the weather. This causes the construction of all kinds of structures to protect us from the elements. The need of food of all kinds caused the railroads and in this man- ner we can trace every desire to do any particular act to arise from our wants and necessities. The desire has stimulated efifort, and effort has devised and conceived structures and methods by which it could be accom- plished. In the effort to build a house certain activities take place involving judgment and discretion. Such ma- terial will be selected as in the judgment of the builder is most suitable. Every act will involve intelligence, in order that the structure shall conform to the mental pic- ture of what the builder wants. In the same manner does everything that we see come to be and exist from the most complicated city block and railroad system to the smallest living organism. In this particular I agree with Mr. Dar- win, who states : **That animals have a capacity to be modified by pro- cesses which their own desires initiate." He states fur- ther in another place that: "Their powers are excited into action by the necessities of the creatures which pos- sess them and on which their existence depends." Again he states : "That from the first rudiment or primordium to the termination of their lives, all animals undergo per- petual transformations which are in part produced by their own exertions in consequence of their desires, aver- THE LIVING STRUCTURES ]55 sions, pleasures, pains, irritations or associations." You will see then that all living structures are caused by rea- son of the desires of the parties who construct them, which desires arise from the wants and necessities of the parties. The desires will be likely limited to that party's experience or knowledge. Every action in life is traceable to an effort to adjust and adapt itself to meet conditions and external forces. Professor Haeckel, the great German biologist states, "Cells are grouped together as builders or sculptors because they alone in reality build the organism." Still Mr. Haeckel claims that the actions of the cells are caused by merely chemical and mechanical forces, — that they are not intelligent beings. It seems absurd to me to claim that the living beings who are the sculptors and builders of all living structures have no intelligence. It is simply unthinkable. In reference to the general course of development of animals he states : "For example — from the fact that the human egg is a simple cell, we may at once infer that there has been at a very remote time a unicellular ances- tor of the human race, resembling the amoeba. Again from the fact that the human embryo originally consists merely of two simple germ layers we may at once safely infer that a very ancient ancestral form is represented by the two layered gastraea. A later embryo form of the human being points with equal certainty to a primitive worm like ancestral form, which is related to the sea- squirts or ascidians of the present day. "If we go back to still earlier stages of development we are unable even to discover any distinction between the embryos of these higher vertebrates and those of the lower, such as the amphibia and fishes. Finally if we go still further back to the construction of the body from 156 CELL I INTELLIGENCE THE CAUSE OF EVOLUTION Fig. 30. — Kinbryos in three stages of development. — H.^eckel. THE LIVING STKIX'TIKES 157 Fig. 31. — Embryos in three stages of development. — Haeckel. 158 CELL INTELLIGENCE THE CAUSE OF EVOLUTION the four secondary germ layers, we may make the surpris- ing discovery that these same four germ layers exist, not only in all vertebrates but also in all higher inverte- brates and that they are everywhere concerned in the same way in forming the fundamental organs of the body. And if then we inquire into the origin of these four sec- ondary germ layers, we find that they develope from the two primary germ layers, which are identical in all ani- mals with the exception of the lowest division, the pro- tista. Finally we see that the cells which compose the two primary germ layers universally originate by fission from a single simple cell, from the egg cell." You will notice from this statement that the course of development or building of an animal, including man, takes place in the same manner in one animal as in an- other, and his illustrations clearly show the similarity of all animals in the lower stages of development. Figs. 30 and 31 show how the cell begins with the small and simple and gradually builds the complicated living structures. You see in the turtle how the cells have out- lined the shape and frame of the shell. It shows that every move is for the purpose of building a moveable cell colony, which shall be covered with a protective armor. Tn the same manner you can see a purpose and intention of the builders in any other structure, as soon as it is partly completed, just as you can see in a partly com- pleted house or automobile the intention of the builders. You can see a purpose in every act ; every brick and piece of material must be placed exactly where it belongs ; every part of the machine must be placed with a purpose and intention of working in harmony with every other part. A being without intelligence could never work in this way with a purpose and with an intention of producing THE LIVING STRUCTURES 159 a work of art. Intelligence and skill of the highest order is required to produce these well balanced and highly complicated structures we call animals and plants. The common frog is a good illustration of the course and gen- eral development of an animal. He begins as a single cell which multiplies into enormous colonies which again group themselves into a fish. This fish gradually changes into the perfect animal or frog. This shows how the cells start building with a purpose and continue as far as t ^ /^ -^ He Fig. 32. — Tadpoles .and Frog; a, tadpole with branching external gills; h, gills absorbed and hind legs have appeared; c, fore legs have appeared; d. tail shrunk and legs enlarged; e, perfect, young frog, — tail entirely disappeared.

This particular kind of cell has been building these structures, and that is the extent of its skill and experience. In the same manner some peo- ple or animals have had experience in building certain kinds of structures and houses, and they always build those and none other because they are the only kind they know how to build. That point will be more fully consid- ered under the cause of inheritance. It must be clear to the reader by this time that all 160 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Structures in life are made for a purpose in a similar man- ner as all structures put up by man are built for a pur- pose. Living structures are made to move in air, earth or water or to remain stationary on the earth. In the same manner we build structures to move through the air, over the earth and water. It requires intelligence in the builder to produce these structures. For instance, to build a wagon, the builder must know how and where to obtain the wood, iron and other material, and he must have an idea of what he is about to do. Every move must be correct and for the purpose of completing the wagon. He must have knowledge of the strength of materials in order to produce a wagon that will carry the ordinary load. In other words to produce any structure designed for a purpose, requires intelligence. If it is to be a land animal, it must be built to occupy and move over the sur- face of the earth in a certain way. There are enemies, weather and elements to contend with, and these must all be considered in the making of the machine or moving habitation. The experience of the past must be there to o^uide the builder. From those experiences he must form ideas that guide his actions. The ear is made for hearing, just as a knife is made for cutting. These are both in- struments made for a purpose and are produced by in- telligence and not by chance. The eyes are made for see- ing, just as opera glasses are made to help us see better. The cell completes the structure little by little for a pur- pose, just as if it had a model before it. What is the difference between the act by man of building huts and houses and the same act by the muskrat or the beaver. Consider how they all work in harmony for a purpose just the same as man. The birds build nests and a home to raise a family, so does man ; the birds sing and display their beauty to attract the opposite sex, so does the THE LIVING STRUCTURES 161 human race. The bird is made to sail through the air. Consider how perfectly everything is calculated and ad- justed to effect that purpose. The bones are all made hollow and extremel}^ light, even lighter than aluminum. Those little animals we call cells build and produce these structures and attend to every detail in their production. Think of the factors entering into the construction of the eye. It is made to receive an image like a photographic plate with the purpose of transferring impressions and images received to the brain cells. Every step in the pro- duction of the eye must be exactly calculated, and every act performed with a purpose in view. Think of the per- fect adjustment of the crystalline lens, vitreous humor, and cornea of the eye and how the light is continually regulated by those cells who have charge of the opening and closing of the pupil of the eye to adjust the intensity of the light falling on the retina. In reference to the de- velopment of the eye Mr. Haeckel has the following to say: "The essential difference between the real eye and a part of the skin that is merely sensitive to light is that the eye can form a oicture of objects of the outer world. This faculty of vision begins with the formation of a small convergent lens, a bi-convex refracting body at a certain spot on the surface. Dark pigment cells, which surround it. absorb the light rays. From this first phylogenetic form of the organ of vision up to the elaborate human eye, there is a long scale of evolutionary stages — not less ex- tensive and remarkable than the historical succession of artificial optical instruments from the simple lens to the complicated modern telescope or microscope. This great "wonder of life" — the long scale of the evolution of the eye — has an interesting bearing on many important ques- tions of general physiology and phylogeny." 162 CELL INTELLIGENCE THE CAUSE OF EVOLUTION Just note how Mr. Haeckel compares the acts of the cell in perfecting the eye with the acts of man in perfect- ing and developing the telescope and microscope. The following statement also by Mr. Haeckel seems to me quite a conclusive admission by him of intelligence in the cell mind : ''The history of civilization teaches us that its gradual evolution is bound up with three different processes : (1) Association of individuals in a community. (2) Division of Jabor (ergonomy) among the social elements and the consequent differentiation of structure (polymorphism). (3) Centralization or integration of the unified whole, or rigid organization of the community. The same fun- damental laws of sociality hold good for association throughout the entire organic world and also for the 2^radual evolution of the several organs out of the tissues and cell communities. The formation of human societies is directly connected with the gregariousness of the near- est related mammals. The herds of apes and Ungulata, the packs of wolves, the flocks of birds often controlled by a single leader, exhibit various stages of social forma- tion as also the swaim of the higher articulates (insects, Crustacea), especially communities of ants and termites, swarms of bees, etc. These organized communities of free individuals are distinguished from the stationary col- onies of the lower animals chiefly by the circumstance that the social elements are not bodily connected, but held together by the ideal link of common interest." If the cell has gone through the same process of social organization and evolution as man, why is he not also the
