How and when did society first recognize women's homoerotic bonds? Were these romantic friendships fully accepted, or were they seen as problematic? Did the women involved see themselves as lesbians? These and other questions have been raised over the past twenty years by historians of lesbian sexuality. When Lillian Faderman in her pioneering survey of European and American lesbians declared the nineteenth century as the golden age of unproblematic romantic friendships, historians quickly responded with evidence to the contrary. Much of this debate has been focused on whether or not women could be considered “lesbian” before they claimed (or had forced on them) a publicly acknowledged identity. But the modern lesbian did not appear one day fully formed in the case studies of the fin-de-siècle sexologists; rather she was already a recognizable, if shadowy, subject for gossip among the sophisticated by at least the 1840s and 1850s. By examining closely a single divorce trial, I hope to show that literary and legal elites acknowledged lesbian sexuality in a variety of complex ways. Their uneasy disapproval encompassed both a self-conscious silence in the face of evidence and a desire to control information, lest it corrupt the innocent. Yet who can define the line between the ignorant and the informed? The very public discussion of the Codrington divorce, and most especially the role of the feminist, Emily Faithfull, in alienating Helen Codrington's affections from her husband, demonstrate the recognition of female homosexual behavior.

Abstract Estrus detection is crucial to an effective AI program. The objective of this study was to assess whether Estrotect Breeding Indicators were comparable to vasectomized gomer bulls wearing chin ball markers to accurately and efficiently identify estrus. It was hypothesized that Estrotect Breeding Indicators will accurately and more efficiently detect estrus than gomer bulls. On day 0, an Estrotect Breeding Indicator was placed on Brahman cows (n = 204) that were kept with four vasectomized bulls for the following 45-day study period. Once estrus was detected via activated heat patch, cows were artificially inseminated 14 hr later and the bull score was recorded on a scale from 1–3 (1- no bull marks; 3- solid bull marks). Cows were continually monitored for return to estrus and a pregnancy diagnosis was conducted on day 110. All cows displaying estrus (n = 137) had fully activated patches, while 67 cows were anestrous for the trial duration. A ROC curve analysis indicated that the sensitivity of the bulls detecting estrus was 77.4% compared with the Estrotect Breeding Indicators. Out of the cows with a fully activated patch, 62.77% (86/137) became pregnant to AI. Of these, 17.4% (15/86) of pregnant cows received a bull score of 1 or 2, meaning there were little to no marks left from the bulls. Failure of bulls to identify estrus can be attributed to bulls’ loss of energy, cows displaying homosexual behavior, bulls staying with a chosen cow, or even calves preventing the bull access to the cows in estrus. In conclusion, the patches detected estrus in a greater number of cows than the action of vasectomized bulls wearing chin ball markers leading to an increased pregnancy rate.
