Acanthamoeba culbertsoni was identified retrospectively in a case of amoebic meningoencephalitis, previously reported by Jager and Stamm (Lancet, 2, 1343, 1972). This is the second report of this species causing secondary infection in man. Positive results were obtained only with anti-A. culbertsoni sera when the brain sections were stained by the indirect immunofluorescence antibody test with ...

We have obtained spectroscopy of Q 1343+266 AB, a pair of quasars at redshift z = 2:03 with a projected separation of 9.5 arcseconds. This system is well-suited for probing the Ly forest, since the two component spectra show several Ly lines in common and several others not. Using Bayesian statistics, under the idealization of uniform-radius spherical absorbers, we nd that the Ly cloud radius a...
