must thank Dr. Newnham, our present resident medical officer at the Evelina Hospital, for aid on several occasions. Mr. Collier, head of the dispensing department at Guy's Hospital, has been kind enough to revise the Appendix of Formulæ, and my brother, the Rev. C. Alfred Goodhart, of Sheffield, and Dr. Lewis Marshall, Surgeon to the Hospital for sick children at Nottingham, have been at much trouble in revising and criticising the proof-sheets. Of the labor thus ungrudgingly bestowed I alone can fully appreciate the value. JAMES F. GOODHART. IV. DIARRHOEA-ENTERO-COLITIS-CHOLERA INFANTUM, V. STOMATITIS-THRUSH-CANCRUM ORIS, VI.

THE DISEASES OF CHILDREN. INTRODUCTION. WHAT is a child, and how the diseases of children differ from the diseases of adult life, are questions which must have confronted all who have written upon the ailments of childhood, and not a little puzzled them for an answer. By the pathologists, indeed, it may well be doubted if any valid reason can be given for separating diseases of children from others, for there are but few morbid changes found in childhood that are not to be seen at one time or another in the bodies of adults. If we run over the various regions of the body, the brain, heart, lungs, lymphatic glands and so on, few, and those but minor, differences can be pointed out between the products of disease in the child and of the same disease in an adult. Some diseases are more common at one time of life than at the other; but should they overstep the limit of age usual to them, they appear in their old form, or with but slight modifications, such as would certainly not justify any one in devoting a "manual" to their description. The bones form the most notable exception to this rule: in rickets, acute ostitis, and some forms of enchondroma we have examples of constancy of peculiarity of morbid deposit ; |
