- 100 -livestock, and this work led to very important results of great practical significance. And after that, a detailed account of it has now been decided. Among the remaining issues under investigation is the discovery of a method to save the shock of Tassos fever after double inoculation in cattle plague. Research was conducted into the nature of the dysentery that occurs in the Egyptian army. It is likely that this research will lead to a change in the opinions followed so far regarding the cause of this disease. A special type of clarification is requested for some types of infant mortality, which are among the most important health issues in this country. Malaria fevers are few in Egypt, and most of what is seen are various fevers, but it is good to discover the sources of infection for these fevers. Many scattered cases of simple malarial fever were observed in the suburbs of Cairo last year. The effect of various chemical substances was tested in killing mosquito larvae that are in the water. Experiments have begun to discover the origin of fish types to eradicate these larvae. The bacteriological research, which was specifically investigating the cause of the spread of plague and its prevalence in terrible places, has concluded. His work was completed. And after that, his report is now ready. The general results remain the same as in other places, meaning that rats and their fleas play a significant role in the spread of the plague. It is necessary to find suitable methods to eradicate rats and their fleas. It is known that the hope of finding a method to eradicate rats now is weak, so it is necessary to kill the fleas, as they are the true carriers of infection from rats to humans. Research is ongoing on this issue now. The Hygiene Institute's work included monitoring the water of Cairo, the rural cities, and Sinai, as well as special bacteriology in 1914. Among the issues currently being investigated is the issue of equipping large rural cities with sewage systems. This research will require extensive experiments to be carried out by the men of the Hygiene Institute. Rules have been established to determine the quality of buffalo milk, and similar rules are being established for cow's milk so that milk can be adequately monitored. A method has been discovered in the bacteriology department to distinguish between buffalo milk and cow's milk, and it will be of great benefit in preventing fraud. Food must be adequately monitored in the Egyptian country, and therefore rules will be established for different types of food, but adequate monitoring requires laws to refer to.
