At the conclusion of the complainant's case, if it appear reasonably certain that the magistrate will "hold" the prisoner for the action of a superior court, the lawyer will then "waive further examination," or, in other words, put in no defence, preferring the certainty of having to face a jury trial to affording in prosecution an opportunity to discover exactly what defence will be put in and to secure evidence in advance of the trial to rebut it. Thus it rarely happens in criminal cases of importance that the district attorney knows what the defence is to be until the defendant himself takes the stand, and, by "waiving further examination" in the police court, the astute criminal attorney may select at his leisure the defence best suited to fit in with and render nugatory the prosecution's evidence. The writer has frequently been told by the attorney for a defendant on trial for crime that "the defence has not yet been decided upon." In fact, such statements are exceedingly common. In many courts the attitude of all parties concerned seems to be that the defendant will put up a perjured defence (so far as his own testimony is concerned, at any rate) as a matter of course, and that this is hardly to be taken against him. On the other hand, if a guilty defendant has been so badly advised as to give his own version of the case before the magistrate in the first instance, it requires but slight assiduity on the part of the district attorney to secure, in the interval between the hearing and the jury trial, ample evidence to rebut it. As illustrating merely the fertility and resourcefulness of some defendants (or perhaps their counsel), the writer recalls a case which he tried in the year 1902 where the defendant, a druggist, was charged with manslaughter in having caused the death of an infant by filling a doctor's prescription for calomel with morphine. It so happened that two jars containing standard pills had been standing side by side upon an adjacent shelf, and, a prescription for morphine having come in at the same time as that for the calomel, the druggist had carelessly filled the morphine prescription with calomel, and the calomel prescription with morphine. The adult for whom the morphine had been prescribed recovered immediately under the beneficent influence of the calomel, but the baby for whom the calomel had been ordered died from the effects of the first morphine pill administered. All this had occurred in 1897--five years before. The remainder of the pills had disappeared. Upon the trial (no inconsistent contention having been entered in the police court) the prisoner's counsel introduced six separate defences, to wit: That the prescription had been properly filled with calomel and that the child had died from natural causes, the following being suggested. 1. Acute gastritis. 2. Acute nephritis. 3. Cerebro-spinal meningitis. 4. Fulminating meningitis.
