Softcover. Zustand: Very Good. Zustand des Schutzumschlags: No Dust Jacket. First Edition. No signatures. Some rubbing to corners of wrappers.; [viii], 78 pages. Page dimensions: 209 x 146mm. A fascinating flashback to see how much computer technology has advanced in a few short decades. This book describes computers having 4 Mhz processors, and 24 Mb hard drives. "Micro-Computers, based on one-chip micro-processors, may be no larger than a typewriter + TV screen. Some are so small that they can fold into a brief-case. They typically work with 8-bit data units (bytes). One suitable for business use will cost between $NZ700 and $NZ40,000 including sales tax." - page 11. A single floppy disk drive will add $600-$2000 into the cost of the computer. ; 8vo.

"The existence of the giant pyramidal cells of the cerebral cortex was not widely accepted until the British psychiatrist Lewis verified the findings of Betz and added further morphological details. William Bevan Lewis (1847-1929), or Bevan Lewis and Bevan-Lewis, as he later called himself, was born at Cardigan in Wales and received his medical training at Guy's Hospital Medical School, London, where he was graduated in 1868. Thereafter he worked at the West Hiding Lunatic Asylum as pathologist and assistant medical officer and carried out his researches on the cortex. He later became professor of psychiatry in the University of Leeds and director of the asylum there. His first paper, written with Henry Clarke (1845-1909), medical officer to the West Riding Prison, appeared in 1878 ("The cortical lamination of the motor area of the brain," Proc. R. Soc., 1878, 27:38-49). Like Betz, the authors recognized the five-layered cortex of Meynert and gave a detailed description of "the ganglionic cells of the fourth layer." These were the Betz cells, the first illustrations of which appeared in this paper (fig. 113). Like Betz they defined a functional area on histological grounds and thereby helped to open the way for the study of precise, functional parcellation of the cerebral cortex. A few months later Lewis published another paper ("On the comparative structure of the cortex cerebri," Brain, 1878, 1:79-96) which extended the earlier observations in man and compared them to the motor area in the cat and to certain cortical regions in the sheep."
