In the present work, the author sets himself the ain, to trace out the effect of of the sunrays upon the fresh and invasive eggs of Ascaris lumbricoides within the limits of geographical co-ordinates 22°21'55"-28°36'37" eastern longitude and 41°41'12"-44°12'50" northern latitude during the months of July and August. Applying an original method, he lets the sunrays shine morning and afternoon upon fresh and invasive eggs, placed at 12°-l5°C and 25°C at different altitudes, namely 0 m., 100 m., 300 m., 550 m., 650 m., 750 m., 960 m., 1350 m., 1700 m., and 2376 m. Through the experiments he made and the results he got, he comes to the following conclusions: 1. There was established a speedy deadly action of the direct sunrays upon the eggs of Ascaris lumbricoides. 2. The sunrays, when the altitude is raised, gradually increase their perilous action upon the Ascaris eggs. 3. The noon sunrays act deadly upon the fresh and the invasive eggs of Ascaris lumbricoides, while the afternoon sun radiation does not manifest a deadly action upon the eggs of this kind of a helminth. 4. The fresh eggs are less resistant to the action of the sunrays than the invasive ones. 5. The perilous action of the sunrays upon the eggs of Ascaris lumbricoides is slower in the big cities than that of the sunrays out of an inhabited place at the same altitude.
