Defendant has moved for complete or partial summary judgment under Rule 56. The question presented is the application of the statute of limitations to a so-called “continuing tort” by the defendant and the effect thereon of the plaintiffs’ definitive ascertainment of a resulting disease during the continuance of the tort.
Plaintiffs are the injured wife and her husband. The facts before us, drawn from the complaint and answer, and answers to interrogatories, are these: As a result of defendant’s contamination of the atmosphere in the vicinity of its manufacturing plant near Reading, Pennsylvania, the wife contracted beryllium poisoning. The wife resides a little more than two miles from the defendant’s plant and has been constantly exposed to the poisoned atmosphere from some time prior to World War II until the present time.
In the fall of 1949, as a result of inhalation of beryllium dust the wife first became ill, manifesting symptoms such as shortness of breath, coughing, loss of weight and general loss of interest. In March, 1953, the illness was definitely diagnosed as beryllium poisoning. This suit was not filed, however, until July 1, 1958.
The defendant pleaded the bar of the statute of limitations in its answer and it clearly is entitled to summary judgment if the statute has run. 6 Moore, Federal Practice (2d ed.), § 56.17 [58], p. 2261. And since this is a diversity action in which all of the operative facts occurred in Pennsylvania, the Pennsylvania law of limitation of actions, statutory and decisional, applies. Guaranty Trust Co. v. York,
What is the date “when the injury was done” which marks the beginning of the statutory two-year period? Is it the fall of 1949, when the symptoms first appeared? Is it March, 1953, when the diagnosis of beryllium poisoning was made? Defendant contends that it is not important whether the date of manifestation of the symptoms or the date of diagnosis of the disease is taken as the beginning of the period, for in either case the two years would already have run before the suit was brought. Defendant, therefore, claims that the statute is a complete bar, or in the alternative at least a bar to that portion of the claim that existed in the period antedating the two years which preceded the suit. Plaintiffs take the opposite view. They contend that this is a “continuing tort”, that the injury done to the wife has continued uninterruptedly to the present time and hence the statute of limitations had not even begun to run when the suit was filed in July, 1958.
Statutes of limitation have as their fundamental basis the elimination of stale claims and the discouragement of delay in seeking legal redress. Their simple provision of a chronological time limit, however, often involves more than a mechanical application of the statute. So it early came to be recognized that the lapse of time prescribed by the statute of limitations would not be applied to bar a suit if the plaintiff was diverted from bringing it by the fraud of his adversary (Bailey v. Glover, 21 Wall, 342,
In the immediate area of the present problem the decisions in various States are in conflict. See Annotation, When limitation period begins to run against cause of action or claim for contracting of disease,
In the Plazak case the facts show that the suit was brought within two years from the time of diagnosis.

The court, however, made no reference to the date of diagnosis or the discovery of the existence of the disease as a datum point for the beginning of the statutory peri

od. This, however, became the crucial element in the subsequent case of Ayers v. Morgan,
The Supreme Court of the United States in Urie v. Thompson,
Other than Plazak and Ayers, Pennsylvania decisional law does not cast much illumination on the problem. 4 Plaintiffs assert that the rule of the Plazak case permits this suit to be brought for all accumulated injury at any time during the continuance of the exposure and within two years after its termination. They urge that this so-called liberal view is not altered because the Ayers case — without referring to Plazak — adopted another so-called liberal principle that in a malpractice case the statute of limitations does not begin to run until the injured patient learns or reasonably should know of the injury.
We believe that where a plaintiff has full knowledge of the illness *456 brought about by defendant's course of conduct the injury has been done and the statute of limitations begins to run at that time. The subsequent continuance of the wrong cannot serve to toll the running of the statute of limitations on the earlier injury of which the plaintiff has knowledge. The case is analogous to a continuing tort by trespass or nuisance committed on another’s land, where the true principle is authoritatively said to be that the statute begins to run from the time that knowledge arises of the injury. 5
It follows that when the diagnosis of beryllium poisoning was made in March of 1953, the injury which until then under both the Ayers case and the Plazak case could be lumped together, amounted to an injury for which the right to redress existed. At that time the statutory period began to run.
We conclude, therefore, that all claims for damages attributable to exposure to beryllium dust which occurred more than two years prior to July 1, 1958, the date of commencement of this suit, are barred by the statute of limitations. But the aggravation of the disease by additional poisoning since July I, 1956, is an injury done to plaintiffs for which the suit was brought within the statutory two-year period. The statute therefore is not a bar, and plaintiffs may recover damages during that period and down to the date of trial. To hold otherwise would be to grant to the defendant a “prescriptive right to contaminate further” the wife plaintiff’s lungs. See Pieczonka v. Pullman Co.,
The defendant’s motion for summary judgment, therefore, must be denied. We may not, however, enter a so-called “partial” summary judgment. Rule 56 does not contemplate summary judgment as to a portion of a single claim. Coffman v. Federal Laboratories,
. There remains another problem which the parties have not discussed. The pleadings and file indicate that on October 22, 1953, the parties entered into a written agreement pursuant to which defendant paid for medical treatment of the wife plaintiff from that date until February 5, 1958, five months before this suit was brought. The agreement has not been made part of the record, but it apparently stipulates that defendant is to be saved harmless from any claims by plaintiffs arising out of the medical treatment furnished. What else the agreement may have provided is not clear. Whether any elements of estoppel may exist, is not shown. The record as it is now before us would not establish an estoppel against defendant’s assertion of the statute of limitations.
Similarly, the parties have argued the case on the apparent assumption that diagnosis of illness is synonymous with knowledge that the injury was inflicted by the defendant. We are not sure whether this was a studied assumption or not.
We shall, therefore, suspend the entry of an order limiting the issue to the aggravation of injury beginning two years prior to the suit so as to afford the parties an opportunity if they wish to supplement the record regarding the dealings between them and regarding knowledge by plaintiffs that the injury was caused by the defendant. At the expiration of 20 days from this date we shall make an order in harmony with the views expressed in this opinion in *457 the light of any additional facts which may be presented in the interim.
ORDER
AND NOW, November 30, 1962, leave is granted to the respective parties to supplement the record within 20 days, by affidavit or supplemental pleadings, regarding the agreement of October 22, 1953, and any of the circumstances relating to the medical treatment supplied by the defendant to the wife plaintiff, and plaintiffs’ knowledge of the responsibility of the defendant for the wife’s illness, after which, in the light of any additional facts which may be presented, an appropriate order will be entered in accordance with the views expressed in the opinion this day filed.
Notes
. Plaintiff claimed he worked until April 5, 1930. The suit was brought March 28, 1932. On his claim, therefore, the suit was brought within two years from the time his employment ceased, which was also the end of his exposure to silicosis. Defendant claimed that plaintiff ceased work on March 18, 1930, more than two years before the suit was brought.
. The diagnosis of silicosis was made some time after April 11, 1930. The suit was brought on March 28, 1932.
