For the benefit of those who are not familiar with the first edition of this work, Dr. Davison states that there are 329 pediatric diseases, which may be combined into 133 groups. There are 164 symptoms and 213 laboratory tests of these conditions. These may be combined and cross indexed, so that from any given symptom the corresponding disease may be deduced. These diseases are further classified as common and uncommon, in the order of their frequency. In the new edition this system has been refined, and many sections have been revised. New methods of diagnosis and laboratory tests have been added from the newer pediatric literature, with an obviously immense amount of study and work.
