Representation of sound pressure and particle motion information in the midbrain of the goldfish.
1. Averaged evoked responses from multiple electrodes in the goldfish midbrain (torus semicircularis) area were recorded in response to acoustic stimulation by loudspeaker and to direct vertical vibration of the head. 2. Relative pressure and displacement sensitivity was such that in the far field, the response to sound pressure would dominate the response to particle motion by 40-90 dB. 3. Swimbladder deflation caused a flat (70-1000 Hz) loss in pressure sensitivity ranging from 20 to over 50 dB, and led to an enhanced response to vibration at low frequencies. 4. The goldfish midbrain is not homogeneous with regard to relative pressure and motion sensitivity.

Poxvirus infection of the skin of an eastern grey kangaroo.
A solitary cutaneous papillomatous lesion, present for 6 weeks, was surgically removed from the hind limb of an 18-month old eastern grey kangaroo (Macropus giganteus). The lesion did not recur within 6 months of excision. Poxvirus particles were demonstrated in epidermal cells of the lesion by electron microscopy.

Fitting problems of the artificial lower limb: the surgeon's contribution.
Difficulties are experienced by the artificial limb maker and fitter when fitting prostheses to some lower extremity amputation stumps. These difficulties, due partly to operative techniques, are outlined, and suggestions are made for their correction.
