    Notes: Shortly after Julian West awakened to Edward Bellamy's utopian Boston of the year 2000, he was given his first look at the city by his host, Dr. Leete. West nearly fainted at the “ prodigious thing which had befallen me.” Still in a daze, he was asked by Dr. Leete what surprised him most about the new Boston. “ I really think,” West responded, “ that the complete absence of chimneys and their smoke is the detail that first impressed me.” The city, as Bellamy went on to describe it, was an affair of fine buildings set in “ inclosures.” There were “ large open squares filled with trees, among which statues glistened and fountains flashed.” Julian West could see the Charles River, a “ blue ribbon winding away to the sunset,” and to the east was the harbor, “ not one of its green islets missing.” West's initial notice of the absence of smokestacks, coupled with Bellamy's first (and almost his only) physical description of the city, pointed up one of the most striking facts about Boston in the year 2000. The new city was park-like, even pastoral, in character. The entire apparatus of industrialism was kept sedulously out of sight, and the landscape, both physical and social, had come to look quite pre-industrial.

    Notes: SUMMARY. Weekly skim-net samples of chironomid pupal exuviae were collected at a single station on the River Chew, Avon, England, from September 1972 to September 1973. Eighty-six types of exuviae were characterized in this study, of which sixty-four made up only 4% of the year's catch. Thirty -eight percent of the year's catch was referable to Micropsectra atrofasciata Kieffer.The samples showed the expected maxima of numbers and species in spring and early summer. The emergence periods for many of the more common species were very extended, with one or more peaks.

    Notes: Abstract AK Herculis is a contact binary of spectral class F with a number of obvious peculiarities such as a displacement of secondary eclipse from phase 0 . P 500, unequal heights of the maxima, and a possibly sinusoidal (≃60 yr) period variation. The light curve is variable and shows erratic short-term behavior, although the latter effects are not unusual for a short period contact binary. Here we present new photoelectric light curves in theB andV passbands and derive several new times of minima. The new observations are compared graphically with seven earlier light curves. We analyzed the new observations and those by Bookmyer (1972) by the method of differential corrections. We find that the temperature difference between components is too large (≃1000 K) for AK Her to be considered a normal W UMa-system, but too small to allow a detached configuration obeying the mass-luminosity law. The solutions of both series of observations clearly indicate a contact configuration. Other unusual findings include a bolometric albedo greater than 2, and rather low values for the limb-darkening coefficients. We offer some possible reasons for these peculiarities. The mass ratio seems well determined from the photometry and is about 0.26, which is much lower than assumed in most earlier papers. The brightness and color of the known visual companion, ADS 10408B, were found by the differential corrections program. They agree, within observational error, with values found directly at the 200-in. telescope by Eggen, despite the fact that the B component contributes only a few percent of the light of the multiple system. The suggestion by Schmidt and Herczeg (1959) that a fourth body is responsible for the sinusoidal period variation seems stronger now than when first proposed. To encourage a search for this hypothetical component, we have tabulated expected values for its angular separation and relative mass with respect to the eclipsing pair, as well as the amplitude of the expected variable proper motion of the eclipsing pair. Discovery as a visual component seems impossible with present means, but the variable proper motion should be detectable. Thus we suggest that ADS 10408A (AK Her) be observed astrometrically. If a search for the predicted variable proper motion proves negative, mass transfer would remain the only plausible mechanism to explain the period change. We advance a different reason than did Schmidt and Herczeg to explain the phase lag of secondary eclipse.

    Notes: Abstract Skylab soft X-ray observations of two lower coronal limb events and corresponding Hα observations (Skylab and ground-based) are analyzed. We discuss the morphology and evolution of an eruptive prominence occurring on 21 August 1973, beginning (in Hα) at about 1300 UT and of a surge on 4 December 1973, beginning at about 1758 UT. For the eruptive prominence, measured X-ray flux is used in the determination of line-of-sight temperatures, emission measures, and electron densities. A peak temperature of 8.5 × l06 K and densities to 3.5 × l09 cm-3 are derived. A time-dependent, two-dimensional, single-fluid magnetohydrodynamic computer code has been used to simulate the coronal response to these prominences. We find that the coronal response to the observed eruptive prominence may be simulated with a density-dominated pressure pulse at the base of the corona (∼ 30000 km above photosphere), while a temperature pulse of short duration will simulate the coronal response to the surge. Approximately 1031 ergs and 1040 particles (or 1016 g) were deposited into the corona during the eruptive prominence event, while about 1029 ergs and 1038 particles (or 1014 g) were injected during the surge event. A shock wave formed ahead of the ejected material at about 70000 km above the photosphere in the eruptive prominence event and had a velocity of 275 km s-1 at 1.5 r ⊙ above the limb.
