Adverse in effect or tendency, harmful, unfavorable; unfriendly, hostile.
In other words, Mr. Dimmesdale, whose sensibility of nerve often produced the effect of spiritual intuition, would become vaguely aware that something inimical to his peace had thrust itself into relation with him. But Old Roger Chillingworth, too, had perceptions that were almost intuitive; and when the minister threw his startled eyes towards him, there the physician sat, his kind, watchful, sympathising, but never intrusive friend.
