Añadir al carritoHardcover. Condición: Very Good. Estado de la sobrecubierta: Very Good-. 1st Edition. 255pp., vi. No editions, printings or number line cited; same date on title and CP. Shiny forest green cloth with brilliant gilt lettering on spine, blind-stamped Publisher logo at center front cover. Toned (thin line of light brown) across spine ends and very top of boards and inside top cover edges, with very slightest line of thin brown across rear cover top edge (minimized by strong forest green beneath); very small-to-tiny tip wear at corners and across foot and head of spine;very thn line of diminished green across lower rear cover edge [with corresponding faint green on outside (not inside, except for tiny bit of rear cover lower left corner inside)]: it all describes much worse than it is, but there you have it: binding still tight; corners essentially square. Original taupe dustwrapper with black lettering for title and subtitle across top and upper middle front cover, respectively; Publisher name in black across bottom front cover. Spine browned, but with all lettering in black sharp and distinct, eminently readable; browned across top front cover and down right edge, as with rear cover left edge: would appear that a smaller book on the shelf was adjacent to this copy's front cover, a larger book on the shelf adjacent to its rear cover, given the pattern of browning; 1" closed tear down top edge rear cover near top corner; 1/2" closed tear down top right spine corner, with other small chips and tears at corners: now imperfections backed with archival tape and dw in Brodart mylar which forgives sins kindly. Contributions: Niels Bohr, "Quantum Physics and Biology"; A.W.F. Edwards, "Models in Genetics"; H. Kacser, "Kinetic Models of Development and Heredity"; E.N. Willmer, "Tissues in Culture and in the Body"; J.W.S. Pringle,"Models of Muscle"; R.H.J. Brown, "Mechanical Models in Biology"; J.W.L. Beament, "Physical Models in Biology"; J.H. Westcott, Estimation of Values of Parameters of a Model to Conform with Observations"; R.C. Rainey, "Applications of Theoretical Models to the Study of Flight-Behaviour in Locusts and Birds"; J. Dainty, "Electrical Analogues in Biology"; W.K. Taylor, "Computers and the Nervous System"; F.H. George, "Models in Cybernetics"; D.M. Mackay, "Modelling of Large-scale Nervous Activity"; R.A.

Williams, "The Problem of Communication in Biological Teaching"; J.E. Harris, "A Review of the Symposium". Despite minor flaws, book is solid, having only Donald Schon's short vertical markings in the final chapter of the book, a review of the Symposium ( i.e., 6 pp. of 255 pp). Donald Schon's name and address at time of acquisition of book are printed in blue ink on ffep and have been ineffectually blacked out with felt-tip pen. A solid copy, despite peccadilloes.…

Añadir al carritoCondición: Very Good. 1939. Paperback. PENGUIN SPECIALS. This series was for topical interest on contemporary political and social issues. S1 'Germany Puts the Clock Back' by Edgar Mowrer was issued in November 1937. The initial print run of 50,000 books sold out in 4 days. This series achieved very large sales figures, and since Penguin's war-time paper rationing was based on pre-war usage, this greatly helped to sustain Penguin Books during the period of the Second World War. A total of 145 Specials were produced during the war until the end of 1945. A new series of 'Specials' returned to the shelves with the publication of S156The Case for Communism in February 1949. A few of the earlier books were designated 'Pelican Specials' with a blue and white cover, and some found their way into the PELICAN series marked with an 'A'. A number of others were also designated Penguin Handbooks with green covers, and then re-appeared in the newly created series of PENGUIN HANDBOOKS marked with 'PH'-from the Penguin collectors website.

Hardcover. Condición: Very Good. No Jacket. 1st Edition. 1st US edition, 1st printing ; 256 p. : ill., maps ; 25 cm. ; ISBN: 9780394550985; 0394550986 LCCN: 91-41141 ; LC: DU178; Dewey: 994.4/1 ; OCLC: 24795743 ; blue cloth ; no dustjacket ; ex-lib, stamps, labels ; Built upon a penal colony, Sydney is a city that bears the mark of its hard-knocks history. This author weaves that past into the present, finding ghosts of the city's rebellious founders in the vibrancy and puck of today's populace. The result is an intimate portrait of the city that forms the spiritual heart of Australia. ; "Renowned and much-loved travel writer Jan Morris turns her eye to Sydney: 'not the best of the cities the British Empire created . but the most hyperbolic, the youngest at heart, the shinest.'" ; Jan Morris was born in 1926 of a Welsh father and an English mother, and when she is not travelling she lives with her partner Elizabeth Morris in the top left-hand corner of Wales, between the mountains and the sea. She is also the author of six books about cities and countries, two autobiographical books, several volumes of collected travel essays and the unclassifiable Trieste and the Meaning of Nowhere. A Writer's World, a collection of her travel writing and reportage from over five decades, was published in 2003. Hav, her novel, was published in a new and expanded form in 2006. ; VG. Book.…
