Medicine that walks: disease, medicine, and the Canadian plains native people, 1880–1940

work, which would have been invaluable once, may not be noticed by communities whose interests have moved on. The dogs did not only make knowledge, they made material goods. In a fascinating and funny chapter, Todes follows the marketing of pure, dog gastric juice as a remedy for digestive upsets. This leads him to explore the very hard work that Pavlov did to demonstrate the relevance of physiological knowledge to clinicians. Subtly and diplomatically (and quite unlike Bernard), Pavlov wooed the medical community by praising clinical experience as harmonizing with laboratory observations. Finally, Todes pursues Pavlov's nomination for the Nobel prize. Cruelly, it might be said, he got it only just in time. The great edifice of nervous control of digestion which his physiology factory was designed to support was beginning to crumble in the face of the discovery of secretin and humoral methods of digestive integration. This is a magnificent book: a very happy family indeed.
