SPECTATUR (Lat.). The direct and not the remote cause is considered. In many casés important questions arise as to which, in the chain of acts tending to the production of a given state of things, is to be considered the responsible cause. It is not merely distance of place or of causation that renders a cause remote. The cause nearest in the order of causation, without any efficient concurring cause to produce the result, may be considered the direct cause. In the course of decisions of cases in which it is necessary to determine which of several causes is so far responsible for the happening of the act or injury com- plained of, what is known as the doctrine of proximate cause is constantly resorted to in order to ascertain whether the act, omission, or negligence of the person whom it is sought to hold liable was in law and in fact responsible for the result which is the foundation of the action. The rule was formulated by Bacon, and his comment on it is often cited: "It were infinite for the law to judge the cause of causes, and their impulsions one of another : therefore it contenteth itself with the im- mediate cause; and judgeth of acts by that, without looking to any further degree;" Max. Reg. 1. Its subsequent development has resulted rather in its application to new conditions than in deviation from the prin- ciple as originally stated. Proximate cause, it may be generally stated, is such adequate and efficient cause as, in the natural order of events, and under the particular circum- stances surrounding the case, would neces- sarily produce the event; and this having been discovered, is to be deemed the true cause, unless some new cause not incidental to, but independent of, the first, shall be found to intervene between it and the first.

A proximate cause must be the act or omis- sion of a responsible human being, such as in ordinary natural sequence immediately results in the injury; Whart. Neg. § 78: it is a cause which in natural sequence, un- disturbed by any independent cause, pro- duces the result complained of; 160 Pa. 359; and the result must be the natural and probable consequence such as ought to have been foreseen as likely to flow from the act complained of; 112 Pa. 574; 147 id. 44: 14 Allen 290. The practical consideration which the courts have in view is to find a cause from which a man of ordinary expe- rience and sagacity could foresee that the result might probably ensue; Sh. & Redf. Neg. 9. Negligence for example is not ac- tionable unless it is the proximate cause of the injury complained of, but because it is impossible to trace back the chain of causes indefinitely, the law stops at the first link in the chain of causation and looks to the person who is the proximate cause of the injury; id. For example, where a train was forty- five minutes late when a gust of wind threw it from the track and injured a pas- senger; it was held that though the train would have escaped the gust of wind had it been on time, yet the accident was nei- ther the natural nor probable consequence of the delay, and only an independent force took advantage of it and the company was not liable to the passenger; 3 Neb. 44. So when a horse hitched to a defective hitch- ing-post was frightened by the running away of another horse, and broke the post and ran over a person in the street, the latter could not recover against the owner of the post for the defect in the post as the cause of the injury'; 83 III. 347. The act of a third person intervening will not excuse, if such act ought to have been foreseen; 111 Mass. 136; but where the defendant sold gunpowder to a child, and the parents took charge of it and let the child have some, the sale was held too re- mote as a cause of injury to the child by an explosion; 103 Mass. 507; on the other hand an injury from a railway accident, having been the direct cause of a diseased condition which resulted in paralysis, was
