Abstract Observations of sea surface and land–near-surface merged temperature anomalies are used to monitor climate variations and to evaluate climate simulations; therefore, it is important to make analyses of these data as accurate as possible. Analysis uncertainty occurs because of data errors and incomplete sampling over the historical period. This manuscript documents recent improvements in NOAA’s merged global surface temperature anomaly analysis, monthly, in spatial 5° grid boxes. These improvements allow better analysis of temperatures throughout the record, with the greatest improvements in the late nineteenth century and since 1985. Improvements in the late nineteenth century are due to improved tuning of the analysis methods. Beginning in 1985, improvements are due to the inclusion of bias-adjusted satellite data. The old analysis (version 2) was documented in 2005, and this improved analysis is called version 3.

Despite his important political and literary activities, Blatta Gäbrä Egzi'-abehēr is almost unknown to scholars of Menilek's Ethiopia. This historical period is not particularly well researched, and the author stands out as one of the few Ethiopian intellectuals to have written such an important number of literary works focused on nationalistic and anti-Italian feelings. The Amharic/Ge'ez text under discussion, his letter to Menilek written in 1899, is a remarkable document from this point of view because it reveals a strong opposition to colonialism and the Italian occupation of Eritrea. This document is one of the first Ethiopian sources to testify to the growing nationalism and the growth of concepts of unity and independence. It allows us to consider more carefully the beginning of an Ethiopian secular ideology of the modern state. And such an ideology must be placed in the colonial context. The letter to Menilek raises some important questions regarding the new source material in the late nineteenth century available to historians of modern Ethiopia. A translation of the text is given as well as a comment on its historical significance.

Sociology of religion in the West is a field of knowledge with at least 100 years of history. As a science and as a discipline, the sociology of religion has been developing in most Western universities since the late nineteenth century, having established traditions, forming well-known schools, areas related to the names of famous scholars. The total number of researchers of religion abroad has never been counted, but there are more than a thousand different centers, universities, colleges where religion is taught and studied. If we assume that each of them has an average of 10 religious scholars, theologians, then the army of scholars of religion is amazing. Most of them are united in representative associations of researchers of religion, which have a clear sociological color. Among them are the most famous International Society for the Sociology of Religion (ISSR) and the Society for Scientific Study of Religion (SSSR).

John Lloyd Williams was an authority on the arctic-alpine flora of Snowdonia during the late nineteenth century when plant collecting was at its height, but unlike other botanists and plant collectors he did not fully pursue the fashionable trend of forming a complete herbarium. His diligent plant-hunting in a comparatively little explored part of Snowdonia led to his discovering a new site for the rare Killarney fern (Trichomanes speciosum), a feat which was considered a major achievement at the time. For most part of the nineteenth century plant distribution, classification and forming herbaria, had been paramount in the learning of botany in Britain resulting in little attention being made to other aspects of the subject. However, towards the end of the century many botanists turned their attention to studying plant physiology, a subject which had advanced significantly in German laboratories. Rivalry between botanists working on similar projects became inevitable in the race to be first in print as Lloyd Williams soon realized when undertaking his major study on the cytology of marine algae.
