Do you want to know more about a starfish dissection? The 7th-grade students at Big Rapids Middle School dissected a starfish, this is what one of the students learned. Dissecting starfish gave students the opportunity to learn and explore the anatomy of a saltwater organism. To start, the three things the class learned in the dissecting were the tube feet, madreporite, and ampulla. Tube feet function in locomotion, feeding, and respiration. The tube feet in a starfish are in the grooves along the arms. They operate through hydraulic pressure. They are used to pass food to the oral mouth at the center and can attach to surfaces. The next thing the class learned was the madreporite and it’s located on the aboral surface of the sea star, which

Eva Ibbotson - a Company of Swans

...A Company of Swans Chapter One There was no lovelier view in England, Harriet knew this. To her right, the soaring towers of King's College Chapel and the immaculate lawns sloping down to the river's edge; to her left, the blue and gold of the scillas and daffodils splashed in rich abundance between the trees of the Fellows' Gardens. Yet as she leaned over the stone parapet of the bridge on which she stood, her face was pensive and her feet— and this was unusual in the daughter of a professor of classics in the year 1912— were folded in the fifth position. She was a thin girl, brown-haired and brown-eyed, whose gravity and gentleness could not always conceal her questing spirit and eagerness for life. Sensibly dressed in a blue caped coat and tarn o'shanter bought to last, a leather music case propped against the wall beside her, she was a familiar figure to the passers-by: to ancient Dr. Ferguson, tottering across the willow-fringed bridge in inner pursuit of an errant Indo-Germanic verb; to a gardener trimming the edges of the grass, who raised his cap to her. Professor Morton's clever daughter; Miss Morton's biddable niece. To grow up in Cambridge was to be fortunate indeed. To be able to look at this marvelous city each day was a blessing of which one should never tire. Harriet, crumbling bread into the water for the world's most blase ducks, had told herself this again and again. But it is not cities which make the destinies of eighteen-year-old girls, it is people— and...

Interpretation of Dreams

...The Interpretation of Dreams Sigmund Freud (1900) PREFACE TO THE THIRD EDITION Wheras there was a space of nine years between the first and second editions of this book, the need of a third edition was apparent when little more than a year had elapsed. I ought to be gratified by this change; but if I was unwilling previously to attribute the neglect of my work to its small value, I cannot take the interest which is now making its appearance as proof of its quality. The advance of scientific knowledge has not left The Interpretation of Dreams untouched. When I wrote this book in 1899 there was as yet no "sexual theory," and the analysis of the more complicated forms of the psychoneuroses was still in its infancy. The interpretation of dreams was intended as an expedient to facilitate the psychological analysis of the neuroses; but since then a profounder understanding of the neuroses has contributed towards the comprehension of the dream. The doctrine of dream-interpretation itself has evolved in a direction which was insufficiently emphasized in the first edition of this book. From my own experience, and the works of Stekel and other writers, [1] I have since learned to appreciate more accurately the significance of symbolism in dreams (or rather, in unconscious thought). In the course of years, a mass of data has accumulated which demands consideration. I have endeavored to deal with these innovations by interpolations in the text and footnotes. If these additions do...
