The water can be taken direct from the supply pipesif a stop-cock is inserted to regulate the this layer of water is a Fresnel lens, and entirely Fig. Finsen-Reyn lamp in operation. below the apparatus are still two more lenses, between whichis a space which should also be filled with distilled waterto absorb the heat rays. The exposures are of about anhours duration. This apparatus I have seen in operation in Lereddes 31 482 ACTINOTHERAPY clinic, where good results were being obtained. Only onepatient can, however, be treated at a time. The lamp gives the same intensity of light power as theolder apparatus with 20 to 25 amperes. The photographfrom which the illustration was made was loaned by , who has made modifications of smaller hand lamps. Fig. 99.
