    Notes: An unusual case of a dilated pore presenting on the dorsal surface of the glans penis is described. A peculiar periorificial elastosis was noted histologically. The literature of dilated pores is reviewed, and the possible pathogenesis is explored. The conclusion is that the lesion represents a hamartomatous development similar to trichoepithelioma. Advice regarding management is given.

    Notes: The development of pemphigus and bullous pemphigoid antigens in twenty-nine human foetuses aged 9–40 weeks has been examined by immunofiuorescence. Pemphigus antigen was weakly demonstrable in the epidermal intercellular area at 9 weeks and strongly after 12 weeks, Bullous pemphigoid antigen was weak and patchy at 12 weeks and only consistently demonstrable with bright linear immunofiuorescence of the basement membrane zone after 23 weeks. Morphologically detectable epidermal basement membrane is already present by 9 weeks gestation.

    Notes: A girl with severe combined immunodeficiency and pronounced malnutrition from chronic diarrhoea is presented. Immunological reconstitution was attempted by transplantation of bone marrow cells from the HL-A hemiallogeneic father. An initial transplant failed to induce a permanent take of the graft, whereas a second transplant with an increased cell dose ensured a take, which was followed by reconstitution of cell-mediated immune functions. Fractionation of the transplanted bone marrow cells apparently led to a delay in development of graft-versus-host symptoms. Germ-free isolation and extensive bacterial decontamination markedly reduced the microbial flora and was highly protective against contaminating microorganisms but failed to eradicate completely one strain of Escherichia coli that had invaded the child before institution of this regimen. During a moderate, delayed graft-versus-host reaction this strain caused widespread severe infection, to which the child succumbed 10 weeks after the second transplantation. This child presented some additional features, the most conspicuous being a deficiency of erythrocyte adenosine deaminase.

    Description / Table of Contents: Abstract A sequence of 34 photographs of the main spot of the group H 26 (Daily Maps of the Sun, Freiburg 1970, Rome number 5847) has been obtained with the 38 cm refractor of the Pic-du-Midi Observatory, showing throughout a resolution very close or equal to 0′'.3. An interval of 3 hr is covered. The pictures taken at intervals of 6 min approximately permit to study the fine structure of the penumbra and associated phenomena: (a) The penumbra appears to consist of bright grains, generally lined up in the form of filaments, showing up against a dark background (see Figure 1). (b) The bright grains form all over the penumbra (see Figure 5). (c) They move toward the umbra of the spot. Their horizontal velocity is zero at the border penumbra-photosphere and maximum at the umbral border (0.5 km s−1) (see Figures 3,4 and 8). Therefore, the grains never originate in the photosphere nor do they enter it. (d) They disappear in the penumbra proper or, if they form near enough to the umbra and live long enough, they can enter the umbra and their appearance becomes similar to that of umbral dots. (e) The life time of the grains is a function of their place of origin within the penumbra: It is maximum and of the order of 3 hr or more for those forming in the middle part of the penumbra, and 50 and 40 min respectively for the points formed in the inner and outer part of the penumbra.
    Notes: Resumé Une séquence de 34 photographies de la tache principale du groupe H 26 (Daily Maps of the sun, Freiburg 1970, Rome number 5847) a été obtenue avec le réfracteur de 38 cm, de l'Observatoire du Pic du Midi, avec une résolution égale ou trés proche de O′'.3. Un intervalle de 3h étant couvert, ces clichés, pris à environ 6 min d'intervalle, permettent l'étude des structures fines de la pénombre et des phénomènes associés: (a) La pénombre apparaît constitutée de grains brillants, généralement alignés en filaments, qui se détachent sur un fond sombre (voir Figure 1). (b) Les grains brillants se forment dans la pénombre (voir Figure 5) (c) Ils se déplacent vers l'ombre de la tache. Leur vitesse horizontale est nulle au bord photosphère-pénombre et maximum au bord de l'ombre (0.5 km s−1) (voir Figures 3, 4 et 8). Ainsi ils ne peuvent entrer dans la photosphère ni en provenir. (d) Ils disparaissent dans la pénombre elle-même ou bien, s'ils naissent suffisamment prés de l'ombre et si leur durée de vie est assez longue, ils rentrent dans cette dernière tandis que leur aspect se rapproche de celui des points ombraux, pour finallement disparaître en s'estompant. (e) La durée de vie des grains dépend de leur lieu d'apparation dans la pénombre: il est maximum et de l'ordre de 3 h ou plus dans la pénombre centrale, et de 50 et 40 min respectivement pour ceux formés dans les régions intérieures et extérieures de la pénombre.

    Description / Table of Contents: Abstract The microphotometric analysis of the fine structure of a sunspot penumbra, photographed in white light with the 38 cm refractor of the Pic du Midi Observatory with a resolution very close to 0′'.3, allows to give from it, at λ5280, the following picture: the penumbra appears to consist of bright grains, lined up in the form of filaments, with an average brightness I/I b = 0.95 of average width 0″.36 (270 km) and which cover 43% of its surface, showing up a dark background of brightness I/I d = 0.6 nearly uniform.
    Notes: Resumé L'analyse microphotométrique des structures fines de la pénombre d'une tache solaire, photographiée en lumiére blanche au Pic du Midi avec une résolution de l'ordre de 0′'.3, permet d'en donner, à λ15280, l'image suivante: elle est constituée d'un fond sombre (espaces interfilamentaires) de brillance I/I d = 0.6 à peu près uniforme, avec un léger gradient radial, sur lequel se détachent des grains brillants alignés en filaments, de brillance moyenne I/I b = 0.95, de largeur moyenne 0′'.36 (270 km) et qui recouvrent 43% de sa surface.
