Foreword My friend Dr. S. Khanna, M. B. B. S., D. P. H. has been rendering great service in popularising the advance made by medical science in the West for the benefit of that section of the medical profession in North India, which still successfully practices the ancient and well tried Ayurvedic system of medicine and treatment. Dr. Khann's present work 01 "Clinical Pathology" including Laboratory Methods of diagnosis, Parasitology, Bacteriology and Medical Zoology will undoubtedly add to the knowledge of changes which occur within the Human body due to the presence of certain morbid matters and ACRIDITIES. It will therefore help the physician in treating his patients with a wider and clearer knowledge of the nature and cause of their disease.
