Excerpt from A Guide to the Poisonous Plants and Weed Seeds of Canada and the Northern United States The illustrations are from photographs and drawings made especially for the book. By means of these and by the classification into the groups above referred to, it should be possible for an amateur to identify the plant responsible in an ordinary case of poisoning. No key based on botanical characters has been included, since such a key would be impracticable because of confusion with the numerous non-poisonous forms. At the end of the book, however, a symptoms key has been added. Such a key cannot, in the present state of our know ledge, be made precise. Its purpose is merely to facilitate diagnosis by suggesting the plants that should be looked for when certain symptoms are observed and plant poisoning is suspected.

Progress in Chemical Toxicology, Volume 1 covers the developments in toxicology, including the usefulness of the developed techniques and methods with necessary modifications for toxicological studies. The book describes the isolation and separation techniques for the identification of poisons; the application of gas chromatograph to toxicology; and the pharmacological and toxicological effects aliphatic alcohols. The text also discusses the isolation, purification, identication, and the toxicology of acidic and neutral poisons, ataraxics and nonbarbiturate sedatives. The determination of antiarthritics, antihistamines, and thymoleptics; the physicochemical properties for the identification of narcotics and related bases; and the toxicity of air pollutants are also considered. The book further tackles the analytical methods for air pollutants; the occurrence, symptoms, and treatment of mushroom poisoning; and the toxic components of poisonous seeds and fruits poisonous seeds and fruits. Toxicologists, chemists, and scientists in forensic science laboratories will find the text invaluable.

Best known for his writings on economic history and communications, Harold Innis also produced a body of biographical work that paid particular attention to cultural memory and how it is enriched by the study of neglected historical figures. In this compelling volume, William Buxton addresses Innis's engagement with the legacy of the fur trader and adventurer Peter Pond. Harold Innis on Peter Pond comprises eight texts by Innis, including his 1930 biography of Pond as well as his writings on the explorer's myriad activities. The book also features a collection of eight letters exchanged between Innis and Florence Cannon, a descendent of Pond with a strong interest in her ancestor's life and times, and an unpublished 1932 article on Pond's 1773–75 activities as a fur trader on the upper Mississippi, written by Innis's former student R. Harvey Fleming. Situating Innis's writings on Pond in relation to his broader body of biographical work, Buxton interprets what these texts tell us about Innis's intellectual practice, historiography, and the writing of biography. The book explores how Innis's perspectives shifted with changing intellectual and political circumstances and shows that his advocacy of Pond as an unrecognized "father of confederation" challenged conventional views of Canadian nation-building. A critical edition of previously overlooked biographical texts, Harold Innis on Peter Pond traces what these writings disclose about the biographer's character and values even as they discuss their subject.

The greater cost of marketing live poultry as compared with dressed poultry is partly transportation cost insofar as the poultry is carried by freight. But the major portion is found in the service charges at New York City.
