ABSTRACT
Their proximity to Eastern Virginia's abundant waterways has given the authors experience in managing the destructive tenosynovitis and deep tissue infections caused by M marinum. They present nine cases, discuss diagnosis and treatment, review the literature, and urge urban physicians to be on the alert for the disease in patients recently returned from fishing trips.

Eighteen different treatments against sheep headfly (Hydrotaea irritans) were tested on Scottish blackface and Swaledale ewes and lambs. Gamma-HCH + paradichlorobenzene gave consistently better control than crotoxyphos cream. Pyrethroids in sprays or incorporated into eartags were relatively ineffective. Pyrethroid pour-ons gave good control, but in a year of low headfly attack they were not as effective as HCH + paradichlorobenzene. Liveweight gain was improved by treatment with HCH + paradichlorobenzene and significantly improved by treatment with deltamethrin pour-on.

Headfly caused irritation to sheep in Northumberland from late June of each year 1973 to 1975. Numbers of headflies caught in sweep nets declined sharply from early August 1973 and 1975 but remained fairly high in 1974 until mid September. Attacks on sheep followed a similar pattern. The effectiveness of a number of fly repellent applications was examined. Headcaps gave good and sometimes complete protection.

Spatially resolved holographic spectral analysis has been applied to the 10-cm diam near-field beam of a pulsed HF laser. The hologram recording procedure is described, and the spatial relief fringes of the resulting phase hologram are discussed.
