SUMMARY The functional morphology of venom injection in Crotalus atrox was explored using high-speed digital videography combined with direct recording of venom flow using perivascular flow probes. Although venom flow was variable, in most strikes the onset of venom flow was coincidental with fang penetration, and retrograde flow (venom suction) was observed prior to fang withdrawal. The duration of venom flow was consistently less than the duration of fang penetration. The occurrence of retrograde flow, ‘dry bites’ (which accounted for 35 % of the strikes) and unilateral strikes all support a hypothesis for venom pooling in the distal portion of the venom-delivery system. No significant difference in temporal or volumetric aspects of venom flow were found between defensive strikes directed at small and large rodents. With the species and size of target held constant, the duration of venom flow, maximum venom flow rate and total venom volume were all significantly lower in predatory than in defensive strikes.

Optical Emission Spectra

A recording system and computer can be used for the complete spectrochemical analysis of photographed spectra. Transmission values, taken at equal intervals of travel along the spectrum are transferred to magnetic tape with high precision, high speed, and in a form suitable for computer processing. This processing may include wavelength determination, line identification, and plate calibration.

Film Specimen

Vapor deposited layers of certain materials show a diffuse, amorphous diffraction pattern; carbon is an example. Such patterns may not be interpreted by identification of Bragg peaks, instead the intensity profile is measured with all possible precision and the data is then treated by computer, yielding what is, in effect, a spectrum of interatomic distances within the specimen.The direct recording electron diffraction technique is particularly suited to the measurement of diffuse patterns. The electron beam from a conventional electron gun and magnetic lens arrangement produces a transmission diffraction pattern of a thin film specimen. Coils beneath the specimen produce a magnetic field which deflects the diffraction pattern across a very small aperture.
