Book Description
This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 Excerpt: ...earth. r' = radius of moon, or other body. P = moon's horizontal parallax = earth's angular semidiameter as seen from the moon. f = moon's angular semidiameter. Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

Book Description
The Budgerigar is arguably Australia's best-known bird. At the same time, it is so ubiquitous that not everyone knows that it is Australian. Nor do many realise that the multicoloured bird that comes to mind--not to mention today's super-sized, extravagantly coiffed show budgie--is as different from the free-living original as a chihuahua from a wolf. Far from the cosy domestic lives our pet budgies live today, the native budgerigar has lived millennia of boom-bust cycles in the arid inland of Australia. Life was often short; if they were not fodder for predators, they starved or had to struggle their way to districts closer to the coast. For the Warlpiri and their Arrernte neighbours around Alice Springs, the Budgerigar (in its ancestral form) was a totem animal, featuring in art, ceremonies, songlines and legends. Since 1840, when ornithologist John Gould took living specimens to London, this little parrot has been on a remarkable journey. The Budgerigar was Australia's first mass export; its story includes British queens and nobles, Japanese princes and Hollywood stars. It has won the hearts of British spies and world leaders, including Churchill, Stalin and Kennedy. Taking the reader from the Dreamtime to the colonial live bird trade, the competitive culture of the showroom and today's thriving wild flocks, Flight of the Budgerigar is the authoritative history of the Budgerigar, written by respected ornithologist Dr Penny Olsen, and lavishly illustrated in full colour.

Book Description
A history of pets and their companions in Britain from the Victorians to today. Pet Revolution tracks the British love affair with pets over the last two centuries.

Historians Jane Hamlett and Julie-Marie Strange show how the pet economy exploded—increasing the availability of pet foods, medicines, and shops—and reshaped our modern lives in the process. A history of pets and their human companions, this book reimagines the “pet revolution” as one among many other revolutions—industrial, agricultural, and political—that made possible contemporary life.
