Aksel Wiin-Nielsen (1924–2010)

Aksel Christopher Wiin-Nielsen, professor emeritus of geophysics at the University of Copenhagen, Denmark, died on 26 April 2010 at the age of 85. He was an honorary member of the American Meteorological Society, the former European Geophysical Society, and the Royal Meteorological Society. He received several awards including the 1982 Buys Ballot Medal, given by the Royal Netherlands Academy of Arts and Sciences, and the 1983 Wihuri International Prize, given by the Wihuri Foundation for International Prizes. He will be remembered for his impressive and outstanding leadership in meteorology.

Evidence for the conspecificity of Palisada papillosa with P. perforata (Ceramiales, Rhodophyta) from the western and eastern Atlantic Ocean on the basis of morphological and molecular analyses

Morphological and molecular studies were carried out on Palisada papillosa and P. perforata from the Canary Islands (type locality of P. perforata), Mexico and Brazil. The two species have been distinguished by features of their external morphology such as size and degree of compactness of the thalli, presence or absence of arcuate branches, branching pattern and basal system. A detailed morphological comparison between these taxa showed that none of the vegetative anatomical or reproductive characters was sufficient to separate these species. The presence or absence of cortical cells in a palisade-like arrangement, also previously used to. distinguish these species, is not applicable. The species present all characters typical of the genus, and both share production of the first pericentral cell underneath the basal cell of the trichoblast, production of two fertile pericentral cells (the second and the third additional, the first remaining sterile), spermatangial branches produced from one of two laterals on the suprabasal cell of trichoblasts, and the procarpbearing segment with four pericentral cells. Details of the procarp are described for the species for the first time. The phylogenetic position of these species was inferred by analysis of the chloroplast-encoded rbcL gene sequences from 39 taxa, using one other Rhodomelacean taxon and two Ceramiaceae as outgroups. Relationships within the clade formed by P. papillosa and P. perforata have not been resolved due to the low level of genetic variation in their rbcL sequences (0-0.4%). Considering this and the morphological similarities, we conclude that P. papillosa is a taxonomic synonym of P. perforata. The phylogenetic analyses also supported the nomenclatural transfer of two species of Chondrophycus to Palisada, namely, P. patentiramea (Montagne) Cassano, Senties, Gil-Rodriguez & M.T. Fujii comb. nov. and P. thuyoides (Kutzing) Cassano, Senties, Gil-Rodriguez & M.T. Fujii comb. nov.

Draft of a brief letter requesting Winthrop communicate an arithmetical solution to the Academy of Arts and Sciences.

Daily pocket journal of John and Hannah Winthrop, 1766-1779

Small printed daily pocket journal repurposed by both John and Hannah between 1766 and 1779 to record household accounts including livestock pasturing, income received, and payments to servants, merchants, and tradesmen for food, livestock, clothing, linen, etc. Many of the pages are unused. The January-April pages contain account records from 1766-1779, one page in June has a few accounting notes from September 1779, the rest of June-November is empty, and three books are listed on a November page. The last three calendar pages contain lists of books in Hannah's handwriting dated 1773 and August 1768.
