Biological chemistry is a major frontier of inorganic chemistry. Three special volumes devoted to Metal Sites in Proteins and Models address the questions: how unusual ("entatic") are metal sites in metalloproteins and metalloenzymes compared to those in small coordination complexes? and if they are special, how do polypeptide chains and co-factors control this? The chapters deal with iron, with metal centres acting as Lewis acids, metals in phosphate enzymes, with vanadium, and with the wide variety of transition metal ions which act as redox centres. They illustrate in particular how the combined armoury of genetics and structure determination at the molecular level are providing unprecedented new tools for molecular engineering.

Thomson and Martinet's grammar reference book has become a classic, and one of the most widely-used books of its time. It is a useful source of reference for intermediate to advanced, and for teachers. A Practical English Grammar: Exercises 2 follows the same order as the chapters in the Grammar.

Walter Willapippy is a children's novel set in the mid-1800s outside of London, in the small town of Wilsham. Willapippy, or Pip as he is known in the village, is a unique fellow. He is known for his impeccable fashion habits, his red curly hair, and his crazy inventions. One day while working on his rooftop, Willapippy drops one of his inventions and it almost hits a little boy named Adam Dall, working on the street below. Adam is eight years old, extremely poor and becomes awestruck by the strange contraption. The two meet and strike up and quick relationship. Pip likes Adam so much; he decides to invite him into his strange world of "imagination and inventions." Little does Pip know that what is to follow is a string of events that changes both of their lives forever. Adam and Pip become intertwined in a race against time to save those that are dear to Adam.
