Hernan Cortes

It is a notable fact that Nuño Beltrán de Guzman, whom many regard as second only in importance to Hernán Cortés in the early history of New Spain, should have escaped for so long the detailed attention of historians. Because of this neglect several false notions have gained currency. For instance, it has been customarily assumed that a Nuño de Guzmán, encomendero of Puerto Plata, Española, was the man who became governor of Panuco, president of the First Audiencia of New Spain, and governor of New Galicia; and wide acceptance has been given to the belief that the man who held these important positions in New Spain died a lonely, despised man in the royal prison of Torrejón de Velasco. Recent investigations by the author in the Spanish archives of Sevilla, Madrid, Guadalajara, and Simancas strongly suggest that the Nuño de Guzmán of Puerto Plata was not the same as the more famous Nuño Beltrán de Guzmán of Guadalajara, Spain, who held three important positions in sixteenth-century New Spain. This research has also lent new insights into the life of Nuño de Guzmán of Guadalajara before and after his career in the Indies.

Northern New Spain

This paper uses the 1695 revolt of the O’odham (Pima) in northern New Spain as a window into ritually inflected encounters between indigenous communities and European evangelists. A careful study of the diverse religious and military reports on the O’odham rebellion reveals a more complex rendering of native participation than the dichotomous options of conversion or rejection. Soldiers’ journals, missionary letters, and official reports not only list possible reasons for the uprising, but also help explain the long periods of relative cooperation that preceded and followed it. Even as several O’odham rejected Christian symbols and rituals in 1695, they also welcomed missionaries with crosses, accepted baptism, celebrated feasts, and constructed churches before and after the revolt. At the same time, the uprising exposed internal Jesuit ambivalence about the authenticity of indigenous sacramental participation. While priests like Eusebio Kino believed in a patient and relatively tolerant approach to existing O’odham practices, others like Francisco Xavier Mora insisted on a more immediate and thoroughgoing transformation to European norms. This disagreement and the ensuing gap between early promises and actual implementation help explain shifting O’odham strategies for negotiating missionary encounters.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.

(+)-Scytalone [3,4-dihydro-3,6,8-trihydroxy-l-(2Hj-naphthalenone] and 1,8-di- hydroxynaphthalene (DHN) have been proposed as intermediates of melanin synthesis in the fungi Verticillium dahliae (1, 2, 3, 4) and Thielaviopsis basicola (4, 5). Scytalone is enzymatically dehydrated by V. dahliae to 1,3,8-trihydroxynaphthalene which is then reduced to (-)-vermelone [(-)-3,4- dihydro-3,8-dihydroxy-1(2H)-naphthalenone]. Vermelone is subsequently dehydrated to DHN which is enzymatically polymerized to melanin.Melanin formation in Curvularia sp., Alternaria sp., and Drechslera soro- kiniana was examined by light and electron-transmission microscopy. Wild-type isolates of each fungus were compared with albino mutants before and after treatment with 1 mM scytalone or 0.1 mM DHN in 50 mM potassium phosphate buffer, pH 7.0. Both chemicals were converted to dark pigments in the walls of hyphae and conidia of the albino mutants. The darkened cells were similar in appearance to corresponding cells of the wild types under the light microscope.

Set Up

Freeze-etching electron microscopy is currently one of the best methods for studying molecular organization of biological materials. Its application, however, is still limited by our imprecise knowledge about the perturbations of the original organization which may occur during quenching and fracturing of the samples and during the replication of fractured surfaces. Although it is well known that the preservation of the molecular organization of biological materials is critically dependent on the rate of freezing of the samples, little information is presently available concerning the nature and the extent of freezing-rate dependent perturbations of the original organizations. In order to obtain this information, we have developed a method based on the comparison of x-ray diffraction patterns of samples before and after freezing, prior to fracturing and replication.Our experimental set-up is shown in Fig. 1. The sample to be quenched is placed on its holder which is then mounted on a small metal holder (O) fixed on a glass capillary (p), whose position is controlled by a micromanipulator.
