In the Civil War’s master narrative, the Shiloh and Corinth campaigns figure prominently because they represented more than just the Union’s large-scale military foray into the Confederacy’s vital western river region (specifically the region between the Cumberland and Mississippi rivers), the occupation of slave soil, and the Confederacy’s first major counteroffensive. They also exposed the complex interplay between armies and the places they operated, demonstrated how national objectives played out in local conditions, and revealed the war’s brutal nature. The Battle of Shiloh produced the bloodiest fighting on the North American continent up to that time, precipitated the subsequent Union capture of Corinth, Mississippi, disrupted slavery in the Trans-Mississippi, led to an enormous transfer of power in the western theater, and induced Union policy changes regarding occupation and repatriation of the Southern citizenry. In short, these developments established the foundation for the Union’s successful prosecution of the war.

Three lithospheric cross sections provide a continental-scale synthesis of more than two decades of coordinated multidisciplinary research during the Canadian Lithoprobe project. The sections are based on seismic reflection and refraction data combined with a broad range of geological, geochemical, geochronological, and geophysical data. The dataset is derived from remnants of nearly every kind of tectonic regime, and the geologic history of the entrained rocks spans the Present to the Mesoarchean. The longest of the three cross sections is located within a 6000 km long Trans-Canada corridor traversing the North American continent at 45°N–55°N. From west to east, the profile crosses the Juan de Fuca ridge and active Cascadia subduction zone, the Cordilleran, Albertan, and Trans-Hudson orogens, the Superior Province, the Midcontinent rift, the Grenville and Appalachian orogens, and the Atlantic passive margin. The two northern cross sections include (i) a 2000 km long corridor in northwestern Canada (54°N–63°N) crossing the Cordilleran, Wopmay, and Slave orogens; and (ii) a 1600 km long corridor in northeastern Canada (52°N–61°N) crossing the New Quebec and Torngat orogens, the Nain craton, and the Makkovik and Grenville orogens. The unprecedented scale of the cross sections illuminates the assembly of the North American continent. Relationships between orogens are emphasized; plate collisions and accretions have sequentially stacked orogen upon orogen such that the older crust forms basement to the next younger. The large-scale perspective of these regional sections highlights the subhorizontal Moho that is indicative of either structural or thermal re-equilibration (or both), as few crustal roots beneath orogens are preserved. In contrast, heterogeneities in the lithospheric mantle suggest that, in certain situations, relict subducted or delaminated lithosphere can remain intact beneath and eventually within cratonic lithospheric mantle.

Abstract A quantitative method of predicting precipitation due to large-scale vertical motions is described. A two-level prediction model is applied at the 1000- and 500-millibar pressure levels. Solutions are obtained by graphical procedure which enables one to obtain a 24-hour forecast in about two hours for an area comparable to the size of the North American continent. Tests on ten cases of major cyclone developments show some success.

This paper consists of an epidemiological study of 52 cases of Q fever occurring in metropolitan Adelaide in 1957 and also a description of the results of a survey of 516 sera obtained from abattoir workers.The only case occurring outside the abattoirs was a dairy farmer who probably became infected while visiting the abattoirs. If this were so the incubation period (35 days) of his disease would have been exceptionally long.The general features of the outbreak, which lasted several months, differed from those on the North American continent in that the latter occurred explosively within a few days with very high attack rates. The situation in the Adelaide abattoirs is similar to that in Brisbane, where the disease appears to be endemic. However, unlike in Adelaide, cases are commonly recognized outside the abattoirs in Brisbane.In the abattoirs the disease affected mainly inspectors, those working on killing beef, and those working on offal. Mutton workers were not so severely affected. However, all these groups had similar incidences of low titre antibodies suggesting that in the past Q fever spread equally in all killing departments. In departments not directly associated with slaughtering the incidence both of cases in 1957 and low titre antibodies was relatively small.It was suggested that the epidemiological features of Q fever in Adelaide could be explained by the irregular appearance of animals from infected herds situated perhaps in Queensland—a known endemic area. Perhaps the appearance of such animals in the Adelaide abattoirs might be governed by meteorological conditions such that they were prevented from going to the ordinarily most convenient slaughterhouse.

Austrian Minister

On September 26, 1786, Don Francisco de Miranda, adventurer and patriot, secured a passport from the Austrian Minister in Constantinople which enabled him to continue his “grand tour” to Russia. The nature of Miranda’s subsequent visit, and the extent to which his reception at the court of Catherine II influenced Spanish and Russian policy, assumes significance in the light of events on the North American continent immediately preceding and during his stay in Russia.

The chlorophycean alga Percursaria percursa (Ulvaceae, Ulvales, Chlorophyceae), typical of marine inter-tidal zones, is reported for the first time from hypersaline springs located along the north-western shore of Lake Winnipegosis in Manitoba. Although not usually found inland, P. percursa is the dominant member of microbial mat communities that thrive in shallow pools at the outlets of hypersaline springs.
