A grant of $400,000 has been awarded to the University of Alberta by the National Research Council of Canada for the construction of a “controlled environment greenhouse” in which plants and animals native to the northern areas of Canada can be studied. The greenhouse, which is the first of its kind in Canada, will be one of several controlled environment facilities to be built for the university’s department of botany at a total cost in excess of $1 million … Extending over 1,384 square feet, the greenhouse will contain several rooms in which different northern and mountainous environments can be simulated, so that long-term ecological and physiological studies of arctic, boreal and alpine plants can be carried out.

Rather more than four years ago an American metallurgist, in opening a discussion on the metallurgy of zinc, said wittily: “It is a time-honoured custom to throw bricks at the zinc man. The accusation is that he has borrowed a lime kiln and a gas retort and part of a sulphuric acid plant, hitched them together, and spent the last fifty years in regarding with holy veneration the reactions which take place in that retort. The copper man who thinks of zinc as something with which copper is adulterated to make brass, and the iron man who regards it as a sort of paint for corrugated sheets, and the lead man whose opinion as to zinc is not fit for publication, have long felt that when two or three of the minor details of their respective metallurgies were put in order, they would take a few days and fix up zinc on a modern basis.”
