The author performed the microprecipitation test according to Roth, with use of larvae of Trichinella spiralis. To this test were submitted: 1) 335 healthy persons, 2) 580 persons affected with various diseases (table II) but not suffering from trichinellosis, and 3) 262 swine not infected with Trichinella spiralis. The percentages of positive results obtained in these groups were: 19.40% for the first group, 30% for the second and 26.72% for the third group. This is rather to be considered disadvantageous when evaluating the specificity of the test.

The problem of echinococcosis in Bułgaria is discussed in the light of world literature. The percentages of dogs infested with Echinococci are: 16% in towns, and 40% in the country. The invasion happens frequently also in slaughter animals and was found in 66.5% of sheep, 40.8% of cattle and 4.42% of swine. Infections of man are not rare. In the years 1901-1959 a total of 5617 cases was recorded, what means 350 cases yearly on the average. This concerns particularly rural popu1ation, whereby women more frequently become infected than men. The author also discusses the localization of the parasite in varfous organs of man, the more unique and interesting clinical cases, the mortality and other epiemiological data. This is a summing up of a number of papers and publications which on this subject appeared in the Bulgarian literature.

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.
