In computing the composition of Peking diets, the values in Table I have been used. Most of them have been chosen from Wu (1928), others have been selected as indicated. It is realized that these figures are results of few analyses, that the variations with sampling, season, soil, climate, freshness and technique are great. Many analyses have not been made on local products and even approximately quantitative figures for the vitamin A of some of the common vegetables are not available. However, we believe that only by using in a quantitative way the data on hand, can evaluation of individual diets be approximated and the need for further investigation be revealed. It is hoped that such studies will be made. The present table is offered onIy as a temporary working instrument.

Foreign bodies of all kinds have been found in the urinary tract and present an interesting variety of urological problems. The present report is based upon a study of 31 cases which were observed in the Urological Service of the Peiping Union Medical College Hospital in the period of 17 years from 1921 to 1937 inclusive.

The examination of sputum is a valuable aid in the diagnosis of diseases of the respiratory tract. This is especially true in the case of pulmonary tuberculosis, as the finding of tubercIe bacilli in the sputum establishes the diagnosis in many cases, and earmarks the patient as a contagious individual for whom special isolation is needed. Good results depend on two factors: first, the proper collection of the sputum, and second, the use of a reliable technique in examining the specimen submitted. The reporting of falsely positive results is of particular danger and must be carefully avoided.

Fever may be produced in man by external heat or penetrating heat. External heat, in its simplest form, is induced by the electric light cabinet or fever cabinets by infra-red rays. For the production of penetrating heat the diathermic methods, the electro-magnetic induction and the radiotherms are available. Some use these methods to induce the fever and then maintain it by external heat, such as hot air blowers, electric resisLance and other means.

While congenital cataract is not a rare disease, the occurrence of this malady in many members of the same family is not very frequent.

Law and procedure against hospital physicans or surgeons treating patients not as their individual private practice, but solely for and on behalf of the hospital.

In the previous papers of this series (Winfield 1937, 1937 a, 1937 b) the general plan of this investigation and the results of studies on the epidemiology of Ascaris lumbricoides in a rural population have been presented. It was shown that in spite of unfavorable climatic factors which tend to hold ascaris in check, conditions within the household of the rural family are such as to make it possible for fairly heavy infestations to be built up in a large percentage of the population. It was emphasized that direct contamination of the environment and not vegetables (Winfield and Yao, 1937) seems to be the critical factor. Since life habits and sanitary conditions are somewhat different in the city from those characteristic of the country the study of the operation of these factors under urban conditions may be expected to throw light on their relative importance. In this paper are presented the results of such studies.

The most striking feature of cholera in China is that no regular periodicity of the epidemic can be detected from the records. Years of epidemic prevalence alternate with a number of years of moderate incidence and years when it is entirely absent. Cholera was epidemic in China in 1932 following the Yangtze flood. It was practically absent for 4 years from 1933-1936. In 1937 cholera resumed in epidemic proportion in most of the large cities in China following the Sino-Japanese war.
