This book presents a detailed analysis of children's urine collected between 1963 and 1965. The authors, R. W. A. Oliver and Shirley Ann Oliver, likely utilized data from this specific period to investigate specific physiological or pathological markers in pediatric urine samples. The work aims to provide a scientific baseline or identify trends within this demographic during the mid-1960s.

Given the specific and dated nature of the research, this work is likely of interest to medical historians, researchers specializing in pediatric urology, or those conducting longitudinal studies on health trends. The authority perspective would focus on the scientific rigor of the methodology and the significance of the findings within the context of mid-20th-century medical knowledge. Its value lies in its historical data and potential for comparative analysis with contemporary research.
