PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...

In the twentieth century, dyes, pharmaceuticals, photographic products, explosives, insecticides, fertilizers, synthetic rubber, fuels, and fibers, plastics, and other products have flowed out of the chemical industry and into the consumer economies, war machines, farms, and medical practices of industrial societies. The German chemical industry has been a major site for the development and application of the science-based technologies that gave rise to these products, and has had an important role as exemplar, stimulus, and competitor in the international chemical industry. This volume explores the German chemical industry's scientific and technological dimension, its international connections, and its development after 1945. The authors relate scientific and technological change in the industry to evolving German political and economic circumstances, including two world wars, the rise and fall of National Socialism, the post-war division of Germany, and the emergence of a global economy. This book will be of interest to historians of modern Germany, to historians of science and technology, and to business and economic historians.

Chemistry in the last century was characterized by spectacular growth and advances, stimulated by revolutionary theories and experimental breakthroughs. Yet, despite this rapid development, the history of this scientific discipline has achieved only recently the status necessary to understand the effects of chemistry on the scientific and technological culture of the modern world. This book addresses the bridging of boundaries between chemistry and the other "classical" disciplines of science, physics and biology as well as the connections of chemistry to mathematics and technology. Chemical research is represented as an interconnected patchwork of scientific specialties, and this is shown by a mixture of case studies and broader overviews on the history of organic chemistry, theoretical chemistry, nuclear- and cosmochemistry, solid state chemistry, and biotechnology. All of these fields were at the center of the development of twentieth century chemistry, and the authors cover crucial topics such as the emergence of new subdisciplines and research fields, the science-technology relationship, and national styles of scientific work. This monograph represents a unique treasure trove for general historians and historians of science, while also appealing to those interested in the theoretical background and development of modern chemistry.

First published in 1919. Tilden discusses a compilation of chemical discovery and invention to demonstrate the progress of chemistry in the early 20th century. Divided into 5 sections, chemical laboratories and the work done in them, modern discoveries and theories, modern applications of chemistry, and modern progress in organic chemistry, the author presents an overview of the subject. The final section of the book contains an account of important discoveries which find practical applications and provide new views of the constitution of the world in which we live.

Though rarely noted, women have been active participants in the chemical sciences since the beginning of recorded history. This thought-provoking book brings to life the many talented women who--besides the universally respected Marie Curie--made significant contributions to chemistry. The Rayner-Canhams examine the forces that have defined women's roles in the progress of chemistry, observing that many were thwarted from capitalizing on their achievements by the prejudices of their time. Their book discusses women chemists from as far past as the Babylonian civilization but focuses on professional women chemists from the mid-19th century, when women gained access to higher education. Read this book and learn about the chemist-assistants of the French salons, about independent researchers in the 19th century, about the three disciplinary havens for women in the 20th century, about how war helped bring women into the chemical industry--and much more!
