In a previous publication1 concerned with a system of panophthalmic stereophotography, brief mention was made relevant to a unit of the system used for permanently labeling ophthalmic stereotransparencies. The present communication presents the details of this photographic instrument.
Generally speaking, when a photograph is made there are usually important data pertinent to the picture. The high value of such data is manifest when one is dealing with scientific photography, and it increases still further in importance when the field is medicine, where pathological recordings may have significant direct bearing on the diagnosis, prognosis, and therapy of human afflictions.
There has long been a need for the elimination of the usual data record book or sheets, which are not infrequently mislaid, mixed up, or lost completely after photography. In addition, eradication of the inevitable time-consuming label period once transparencies are returned from the laboratory is desirable. Thirdly, it is evident
