Roughly half the world's population speaks languages derived from a shared linguistic source known as Proto-Indo-European. But who were the early speakers of this ancient mother tongue, and how did they manage to spread it around the globe? Until now their identity has remained a tantalizing mystery to linguists, archaeologists, and even Nazis seeking the roots of the Aryan race. The Horse, the Wheel, and Language lifts the veil that has long shrouded these original Indo-European speakers, and reveals how their domestication of horses and use of the wheel spread language and transformed civilization. Linking prehistoric archaeological remains with the development of language, David Anthony identifies the prehistoric peoples of central Eurasia's steppe grasslands as the original speakers of Proto-Indo-European, and shows how their innovative use of the ox wagon, horseback riding, and the warrior's chariot turned the Eurasian steppes into a thriving transcontinental corridor of communication, commerce, and cultural exchange. He explains how they spread their traditions and gave rise to important advances in copper mining, warfare, and patron-client political institutions, thereby ushering in an era of vibrant social change. Anthony also describes his fascinating discovery of how the wear from bits on ancient horse teeth reveals the origins of horseback riding. The Horse, the Wheel, and Language solves a puzzle that has vexed scholars for two centuries--the source of the Indo-European languages and English--and recovers a magnificent and influential civilization from the past.

When submitting to the reader this my first work on Veterinary Science, I cannot forbear from addressing to him a few remarks, in the hope of explaining some of those peculiarities which it may appear to present. At a period of life, when many men retire from active business, I commenced the study of a new profession. My mind was not prepared to receive instruction through the ordinary process, and I was, by necessity, obliged to be, in a great measure, my own tutor. I found that I could learn only through observation, and this circumstance led me into inquiries which often left me in opposition with established opinions. Hence many of the facts announced in the following pages are new, and not very much contained in them is strictly accordant with the acknowledged authorities. The latter circumstance I may regret, but I have no apology to offer for it. My convictions are derived from the study of Nature, and are conclusions gained from a higher source than conjecture or opinion sanctioned by time or approved by professors.

Edward Mayhew, a veterinary scientist, authored "The Horse's Mouth, Showing the age by the teeth". The author in the book shares illustrations that covers the description of the teeth of a horse, and how it denotes the age of the animal. This book provides basic knowledge of determining the age of horses by using the teeth of the animal.
