The University

The High Voltage Electron Microscope Laboratory at the University of Wisconsin has been in operation a little over one year. I would like to give a progress report about our experience with this new technique. The achievement of good resolution with thick specimens has been mainly exploited so far. A cold stage which will allow us to look at frozen specimens and a hydration stage are now being installed in our microscope. This will soon make it possible to study undehydrated specimens, a particularly exciting application of the high voltage microscope.Some of the problems studied at the Madison facility are: Structure of kinetoplast and flagella in trypanosomes (J. Paulin, U. of Georgia); growth cones of nerve fibers (R. Hannah, U. of Georgia Medical School); spiny dendrites in cerebellum of mouse (Scott and Guillery, Anatomy, U. of Wis.); spindle of baker's yeast (Joan Peterson, Madison) spindle of Haemanthus (A. Bajer, U. of Oregon, Eugene) chromosome structure (Hans Ris, U. of Wisconsin, Madison). Dr. Paulin and Dr. Hanna are reporting their work separately at this meeting and I shall therefore not discuss it here.

Ustilago hordei and Ustilago violacea are yeast-like basidiomycete pathogens ofHordeum vulgare and Silene alba respectively. The mating type system in both species of Ustilago is bipolar, with alleles, A,a, (U.hordei) and a1, a2 (U.violacea) at a single locus. Haploid sporidia maintain the asexual phase by budding, while the sexual phase is initiated by conjugation tube formation between the mating types during budding and conjugation.For observation of budding, sporidia were prepared by culturing the four types on YEG (yeast extract glucose) broth for 24 hours. After centrifugation at 5000g cells were either left unmated or mated in a1/a2,A/a combinations. The sporidia were then mixed 1:1 with 4% agar and the resulting 1mm cubes fixed in 8% gluteraldehyde and post fixed in osmium tetroxide. After dehydration and embedding cubes were thin sectioned with a LKB ultratome and photographed in a Zeiss 9s transmission electron microscope or in an AE1 electron microscope of MK11 1MEV at the High Voltage Electron Microscopy Center of the University of Wisconsin-Madison.

History Of

Empiricisms reassesses the values of experience and experiment in European philosophy and comparatively. It traces the history of empirical philosophy from its birth in Greek medicine to its emergence as a philosophy of modern science. A richly detailed account in Part I of history’s empiricisms establishes a context in Part II for reconsidering the work of the so-called radical empiricists—William James, Henri Bergson, John Dewey, and Gilles Deleuze, each treated in a dedicated chapter. What is “radical” about their work is to return empiricism from epistemology to the ontology and natural philosophy where it began. Empiricisms also sets empirical philosophy in conversation with Chinese tradition, considering technological, scientific, medical, and alchemical sources, as well as selected Confucian, Daoist, and Mohist classics. The work shows how philosophical reflection on experience and a profound experimental practice coexist in traditional China with no interaction or even awareness of each other. Empiricism is more multi-textured than philosophers tend to assume when we explain it to ourselves and to students. One purpose of Empiricisms is to recover the neglected context. A complementary purpose is to elucidate the value of experience and arrive at some idea of what is living and dead in philosophical empiricism.
