    BACTERIOLOGY OF THE EYE CHAPTEE I REMARKS ON TECHNIQUE The Technique of Examining: Cases. It is possible to acquire all the important facts in ophthalmic bacteriology with the aid of but simple apparatus. The mere examination of a film gives a great deal of information, and for the preparation and examination of cultures all that is necessary is the well-known bacteriological apparatus as arranged by Lauten¬ schläger, Bohrbeck, and others. This is quite sufficient if no special scientific research is to be made. We must assume a fair amount of general knowledge, but there are several practical points which must also be emphasized. The Collection and Preparation of Material. It is absolutely necessary, in dealing ivith both external and internal diseases, that material should be collected at a suitable stage of the disease. 1. The Conjunctiva. In many forms of conjunctivitis (e.g., pneumococcal) the charac¬ teristic findings in the secretion can only be obtained during that period in which the disease is developing, or is at its height. When that point has passed, and the inflammation begins to subside, although the discharge may still be profuse, the actual causal agent can dis¬ appear rapidly, but the discharge lessens more slowly. In the stage of regression we find the common conjunctival inhabitants, especially Staphylococci and Xerosis bacilli, in much larger numbers. These previously were often completely—or, at least, to a considerable extent —choked out by some particular pathogenic organism. This is true
