Materials are presented that make the microgrammar Placebo V accessible to inspection.Placebo V should result in a working component of the Itself system which is to enable neuropathologists to use a computer as an ally in the analysis of pictures of brain tissue and of * sets of such pictures.The final Placebo will allow its users to describe such pictures (or 'sections') in English sentences, to query the computer in English, and to issue instructions in English for picture processing. The computer will respond in English.Section I of this paper opens with a key to the format in which the microgrammars are written and proceeds to listings of the rules of Placebos IV and V.Section 2 discusses inclusion problems between context-free machine grammars.Section 3 lists sentences generated from Placebo V rules.
