" . . . you can use such evidence, together with the evidence relating to the charged offences, if you accept such evidence, as establishing a sexual relationship between each of the complainants and the accused. That is, is (sic) the evidence relating to his way of dealing with them, engaging in sexual conduct with each of the complainants, his daughters, all very young girls at the time; in respect of two of them, Counts 1 and 7 being "J" and "V", the use of the plunger, and in respect of "C" and "L" being Counts 12 and 13, the use of the ointment. " If you accept that evidence, it may be that you are satisfied, if you like, that there is a unity of evidence there which is such that you might consider the evidence of a particular daughter concerning a particular activity which is charged against the accused on the presentment as thus more credible or believable. In other words, it bears upon the likelihood that the offence charged was in fact committed. . . . "In addition, the evidence of the uncharged acts may be used by you, if accepted, to place the offences alleged in a true and realistic context and to assist you to evaluate them, for the context can itself bear upon the probability or otherwise of the charged counts having been committed. Having said that, however, I direct you that you cannot reason from the evidence that the accused is the sort of person who would do the acts alleged in the presentment, that is, you cannot reason that the accused has a propensity for dealing with his daughters in a sexual way and therefore he must have done all of these things to them. . . .
