that any influence causing a comparable rise in ocular temperature would produce a comparable result. Hartman has stated[40]: "The physiological and pathological reactions to hyperpyrexia alone, induced by whatever mechanisms, such as hot baths. heated cabinets, diathermy, eat stroke, thermal burns. and microwaves are essentially comparable." Imig[41] plotted temperature gradients induced by 12.25 cm. Microwaves in excised beef eyes and found that the point of maximum temperature was in the vitreous body at the posterior surface of the lens, and hence agreed with the site of damage. Carpenter undertook to study the effect of increasing the ocular temperature by means other than microwave radiation. The beam from a 4.5 amp. carbon arc source, passed through an infrared filter transmitting only wavelengths from 1000 to 3000 millimicra, was focused either on the anterior or on the posterior capsule of the lens in the anesthetized animal. With focus on the anterior capsule and a 6-minute exposure , the cornea was severely burned with subsequent ulceration, scarring, and vascularisation. Although the lens was thereby almost obscured, it remained possible to identify an opacity on or beneath the anterior capsule, in most of the experiments. focus was on the posterior capsule, so that the cornea was spared from burn and suffered only a transient clouding. With duration of exposure of either 5 or 10 minutes, opacities resulted in every case but they were always located in the anterior cortex of the lens. despite the infrared being concentrated at the posterior capsule. The results are in agreement with various other observations on cataracts caused by infrared radiation. The opacities occur typically in the anterior cortex and in this respect differ from those caused by either microwave or ionizing radiation. STUDY OF POSSIBLE INTERFACE EFFECT AT LENS-VITREOUS BODY BOUNDARY Several suggestions have been offered to explain why opacities induced by microwave energy occur typically in the posterior cortex of the lens, just beneath the capsule. One suggestion was that there might be an interface effect at the lens cortex-posterior capsule boundary or at the capsule-vitreous body boundary, with resulting reflection of power to cause a concentration in the posterior
