The advances of Physical Chemistry have an important bearing 

 on the study of all living structures, whether included under Biology, 

 Botany, or Physiology proper. The present book gives the results 

 of the most modern researches in the application of physico-chemical 

 laws to the processes which are characteristic of the living organism, 

 and illustrative examples are specially chosen from the fields of 

 biology, physiology and medicine. An elementary knowledge of 

 physics, chemistry, and mathematics is alone assumed in the reader. 



THE PRACTICAL DESIGN OF 

 MOTOR-CARS. 



By JAMES GUNN, 



Lecturer on ISIotor-Car Engineering at the Glasgow 

 AND West of Scotland Technical College. 



Fully Illustrated. Demy Svo. los. 6d. net. 



A book for all designers and draughtsmen engaged in the practical 

 manufacture of petrol engines and chassis for motor-cars. Each 

 part of the mechanism is taken in detail, and the leading types of the 

 various parts are compared and discussed, often with criticism based 

 on exceptional experience in practice, yet always without bias or 

 prejudice. The simple descriptions and clear diagrams will also 

 render the book of value to the non-technical man, who as owner or 

 prospective buyer of a car is interested in its mechanism.

 Health Officer, but also all who recognize the paramount importance 

 to modern towns of a water-supply above suspicion. A full 

 description is given of modern methods, of filtration.
