Biomathematics
the principles of mathematics for students of biological science

This is an excellent book. It can be consulted for reliable and lucid descriptions (with worked examples) of calculus, Fourier transforms, probability, nomography and differential equations and other aspects of mathematics relevant to medicine and biology. It ought to be still in print. It is a good companion to 'Calculus Made Easy' by S.P. Thomson.
