Belonging to the tribe Klebsielleae found in the family Enterobacteriaceae, the genus Klebsiella is the second most populous enteric genus found in the gastrointestinal tract of man. The genus Klebsiella is named after the late nineteenth century German microbiologist, Edwin Klebs, but the Klebsiella bacillus was for many years referred to as the Friedlander bacillus after being described by Carl Friedlander. The genus consists of four species, recognized by the Centers for Disease Control (CDC), and Bergey's Manual of Determinative Bacteriology, namely, K. pneumoniae (the type species), K. ozaenae, K. rhinoscleromatis, and K. oxytoca. K. pneumoniae is one of a few gram-negative rods that can cause a primary pneumonia.

Abstract Type material for Stenopora tasmaniensis Lonsdale, 1844 was lost in the late nineteenth century, and subsequent descriptions of the genus have been based on material incorrectly assigned to the type species. A neotype is erected for S. tasmaniensis from the original type locality and the genus redescribed. The genus exhibits ramose, frondescent, encrusting, and massive colony morphologies, diaphragms are absent, and acanthostyles of a single size surround each aperture. This single size of acanthostyles aligns with the original type species description; however, it differs from the subsequently accepted genus description and may result in existing species being removed from the genus. Analysis of zooecial characters of a single colony exhibiting both frondescent and ramose morphologies reveals statistically significant differences between subsampled sections, despite being from the same colony. Differences relate to details of zooecial parameters and are not controlled by colony morphology. This variation within a single colony confirms the importance of using qualitative characters alongside quantitative measures in defining Paleozoic bryozoan species.

Children's wages played a central role in family economic strategies in the late nineteenth century. The family budgets collected by the U.S. Commissioner of Labor in 1889-1890 show that life-cycle patterns of savings and debt varied by industry depending upon incomes from children. The consumption patterns of families whose expenditures exceeded their incomes do not show signs of economic distress, and most families whose annual budget was in deficit could expect larger contributions from children in the near future. These patterns suggest that families used borrowing and saving to smooth consumption over the life-cycle as the earning capacity of the family changed.

This essay focuses on agriculture and particularly the “freehold ideal” of independent farmers in the nineteenth-century United States. An odd contradiction of American territorial settlement was the farmers’ simultaneous drive to exploit resources for the market and the aim of many of those actively engaged in settlement to shield themselves from the market’s dangers by acquiring land on the frontier. Clark shows how the ideal of freehold farming, which was so central to the American political economy, was actually threatened not so much from the dangers of the market overwhelming the small farm as from the family farm running out of labor to uphold its own productive capacity. Labor, not land, was the problem confronting the freehold vision, as he argues in a provocative re-reading of late nineteenth-century small farmers’ calls for state intervention.
