The results are collected in Table I, and it may be concluded that:1. Under ordinary conditions in the south of England B. tuberculosis may remain alive and virulent in cow's faeces exposed on pasture land for at least 5 months during winter, for 2 months during spring and for 4 months during autumn. In summer no living organisms were demonstrated after 2 months.2. Under special conditions, e.g. protection from direct sunlight, the survival period may be 4 months during summer. In autumn faeces protected from earthworms, etc., yielded bacilli after 6 months.

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.
