A meeting was held under tlie presidency of Sir Joseph Fayrer, Bart., K.C.S.I., in the Bast Conference Hall of the Imperial Institute, on Wednesday, March 2nd, 1898, and Mr. James Cantlie gave an address on the Organisation of the Colonial Medical Department. The scheme which was proposed for consideration was based upon that contained in a paper on the organisation of the Colonial Medical Serv...

The mol-ecule of the title hydrazine derivative, C15H14N4O6, is essentially planar, the dihedral angle between the substituted benzene rings being 2.25 (9)°. The eth-oxy and hy-droxy groups are almost coplanar with their bound benzene ring [r.m.s. deviation = 0.0153 (2) Å for the ten non-H atoms]. Intra-molecular N-H⋯O and O-H⋯Oeth-oxy hydrogen bonds generate S(6) and S(5) ring motifs, respecti...

Whether it was itself composed orally or in writing, tile Old English Bcowulfis profoundly indebted to the world of orality on which it draws and into which it offers itself as performed artistic uW,;rance.In an obvious sense, then, any infonned interpretation of the poem must, in one of it.smovements, detextualize the text as /hing and reconstitute it imaginatively as event. Yet the performanc...

We argue, contrary to Ostergaard (this issue), that the baseline for measuring priming effects in "remgnit~odidentification" experiments is correctly estimated by the subjects' performance with non-primed items. There is no reason to assume, as Ostergaard (this issue) does, that priming that occurs in a single presentation of the target item is qualitatively different from priming that occurs, ...

Let φ′ ≥ ξ̄. Every student is aware that hy ∼ u. We show that there exists an unconditionally super-Riemannian isometry. W. Moore [25] improved upon the results of L. Harris by extending reversible hulls. So a central problem in formal Galois theory is the classification of numbers.

In the title compound, 2C(12)H(24)N(+)·C(6)H(6)O(7) (2-)·C(2)H(6)O, the cyclo-hexane rings of the cations adopt chair conformations. In the anion, intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, the cations link with the anions via N-H⋯O hydrogen bonds. Weak C-H⋯O hydrogen bonds are also observed. The hy-droxy group of the ethanol solvent mol-ecule is disordered over two sets of sit...

The title complex, [Ni(N(3))(2)(C(10)H(8)N(2))(CH(3)OH)(2)], lies on a twofold roation axis which runs through the Ni(II) ion and the mid-point of the bipyridine ligand. The Ni(II) ion is coordinated in a distorted octa-hedral environment by two azide ligands in a trans configuration. The methanol ligands are in a cis configuration and their hy-droxy groups form intra-molecular O-H⋯(N,N) hydrog...

The asymmetric unit of the title compound, C20H18O6 (systematic name: 1β,3β-dihy-droxy-2β-meth-oxyfuro[4',3',2':4,5,6]-18-norandrosta-8,11,13-triene-7,17-dione), a dihydro derivative of the fungal steroid viridin, contains two mol-ecules with similar conformations. The rings bearing the hy-droxy groups adopt boat conformations. The absolute structure was assigned based on the known chirality of...

Let M be a compact hyperkähler manifold. The hy-perkähler structure equips M with a set R of complex structures parametrized by CP 1 , called the set of induced complex structures. It was known previously that induced complex structures are non-algebraic, except may be a countable set. We prove that a countable set of induced complex structures is algebraic, and this set is dense in R. A more g...

We present millimeter wavelength aperture synthesis observations of TW Hya obtained with the Very Large Array and the BIMA array. Images at 7 mm resolve the dusty circumstellar disk surrounding the star, probing structure to size scales of 0: 00 1 (5 AU). We describe how the long wavelength spectrum and resolved millimeter images constrain the radial distribution of disk surface density.
