Bobbitt, J.

A warranty, express or implied, is contractual in nature. Whether considered collateral thereto or an integral part *359 thereof, a warranty is an element of a contract of sale. 77 C.J.S., Sales § 302; 46 Am. Jur., Sales § 299.

“The obligation arising under a warranty is that of an undertaking or promise that the goods shall be as represented or, more specifically, a contract of indemnity against loss by reason of defects therein.” 77 C.J.S., Sales § 302(d). “The effect of an express warranty undoubtedly is to bind the seller absolutely for the existence of the warranted qualities. If an implied warranty is properly called a warranty, the consequences should be similar. It should make no difference, therefore, whether the seller was guilty of any fault in the matter.” Williston on Sales, Revised Edition, §■ 237.

“Subject to some exceptions and qualifications, it is a general rule that only a person in privity with the warrantor may recover on the warranty.” 77 C.J.S., Sales § 305 (b); 46 Am. Jur., Sales § 306.

Our decisions are in accord. Thomason v. Ballard & Ballard Co., 208 N.C. 1, 179 S.E. 30, and cases cited. Absent privity of contract, there can be no recovery for breach of warranty except in those cases where the warranty is addressed to an ultimate consumer or user. Ordinarily, the ryle that a seller is not liable for breach of warranty-to a stranger to the contract of warranty is applicable to an employee of the buyer. Berger v. Standard Oil Co. (Ky.), 103 S.W. 245, 11 L.R.A. (N.S.) 238. Negligence is the basis of liability of a seller to a stranger to the contract of warranty. Enloe v. Bottling Co., 208 N.C. 305, 180 S.E. 582, and cases cited; Caudle v. Tobacco Co., 220 N.C. 105, 16 S.E. 2d 680.

In Simpson v. Oil Company, 217 N.C. 542, 8 S.E. 2d 813, cited by' appellant, Seawell, J., referring to Thomason, supra, said: “The Court simply held that the purchaser from the retail dealer was neither party nor privy to the contract between the vendor and vendee and, therefore, could not avail himself of any warranty that may -have existed between them.” In Simpson, the basis of plaintiff’s cause of action against the manufacturer and distributor of “Amox” was the warranty to the ultimate consumer appearing on the can sold to the diruggist and purchased from him by plaintiff. In this connection, see Williston, op. cit., § 244(a).

In Davis v. Radford, 233 N.C. 283, 63 S.E. 2d 822, cited by appellant, a retailer of “Westsal,” having been sued for damages for the alleged wrongful death of his customer on account of breach of implied warranty that the product was fit for human consumption, was held entitled to j oin the wholesaler from whom he purchased the product and to recover over against the wholesaler for any loss he might suffer on account of plaintiff’s action. While the question was not *360 presented for decision, the opinion of Devin, J. (later C. J.), intimates that, under the ruling in the Simpson case, the plaintiff, had he elected to do so, could have maintainedi an action against the wholesaler. The pleadings disclosed that “Westsal,” a salt substitute, was a patented bottled product. The wording of the notice or label appearing on the sealed bottle of “Westsal” is not disclosed.

The alleged warranties were made by defendant to the Construction Company incident to the sale of February 15, 1955; andi plaintiff, a stranger to that transaction, does not allege facts sufficient to entitle him to recover damages for breach thereof.

In respect of negligence, this general statement is pertinent:

“One who supplies directly or through a third person a chattel for another to use, is subject to liability to those whom the supplier should expect to use the chattel with the consent of the other or to be in the vicinity of its probable use, for bodily harm caused by the use of the chattel in the manner for which and by a person for whose use it is supplied, if the supplier (a) knows, or from facts known to him should realize, that the chattel is or is likely to be dangerous for the use for which it is supplied; (b) and has no reason to believe that those for whose use the chattel is supplied will realize its dangerous condition; and (c) fails to exercise reasonable care to inform them of its diangerous condition or of the facts which make it likely to be so.” Restatement, Torts, § 388.

“Liability may be imposed on a manufacturer who sells an article likely to cause injury in its ordinary use because of some latent defect or because inherently dangerous in the use to which he knows it will be put.” Lemon v. Lumber Co., 251 N.C. 675, 677, 111 S.E. 2d 868; Tyson v. Manufacturing Co., 249 N.C. 557, 107 S.E. 2d 170; Gwyn v. Motors, Inc., 252 N.C. 123, 126, 113 S.E. 2d 302.

As to the seller of a chattel known to have been manufactured by another, the rule has been stated as follows: “A vendor of a chattel made by a third person which is bought as safe for use in reliance upon the vendor’s profession of competence and care is subject to liability for bodily harm caused by the vendor’s failure to exercise reasonable competence and care to supply the chattel in a condition safe for use.” Restatement, Torts, § 401. Under this rule, liability depends upon whether such seller, by the exercise of reasonable care, could have discovered the dangerous character or condition of the chattel. Restatement, Torts, § 402.

Plaintiff alleges the Loader was “inherently dangerous” and “likely to cause great injury to its operator.” As stated by Rodman, J., in Lemon v. Lumber Co., supra: “It is not sufficient to merely allege *361 that an article is inherently dangerous. Unless the mere descriptive name indicates the dangerous character, the pleader must set out the facts which are relied upon to fix the dangerous character of the article.”

Defendant was not the manufacturer of the International Harvester Loader. It sold and serviced such equipment. While plaintiff alleges defendant knew or by the exercise of due care should have known of the alleged defects, he also alleges the defects were latent and not capable of detection by ordinary care.

Plaintiff alleges the “bucket” and “loading device” were attached (or caused to be attached) to the Loader by defendant. Ordinarily, the descriptive term, International Harvester Loader, would imply a complete piece of equipment. If plaintiff, by such allegations, means to imply that the Loader was to some extent assembled by defendant, nothing alleged indicates this was done otherwise than in the manner prescribed by the manufacturer.

Plaintiff alleges the Construction Company “properly and carefully serviced and maintained” the Loader from February 15, 1955, to July 10, 1956. There is no allegation that the Loader, during this period of use, had either tilted forward without manual activation or that the bucket had raised or lowered itself without manual activation by the operator. Nor do plaintiff’s allegations state or imply that defendant, at any time after February 15, 1955, either inspected or serviced the Loadier or was requested to do so.

Before considering plaintiff’s allegations as to the character of the alleged defects and what occurred when plaintiff was injured, we advert to certain well established legal principles.

The cause of action consists of the facts alleged. G.S. 1-122; Lassiter v. R. R., 136 N.C. 89, 48 S.E. 642. “The complaint must show that the particular facts charged as negligence were the efficient and proximate cause, or one of such causes, of the injury of which the plaintiff complains.” Stamey v. Membership Corp., 247 N.C. 640, 645, 101 S.E. 2d 814. The facts alleged, but not the pleader’s legal conclusions, are deemed admitted where the sufficiency of a complaint is tested by demurrer. Stamey v. Membership Corp., supra.

As stated by Johnson, J., in Shives v. Sample, 238 N.C. 724, 79 S.E. 2d 193: “. . . negligence is not a fact in itself, but is the legal result of certain facts. Therefore, the facts which constitute the negligence charged and also the facts which establish such negligence as the proximate cause, or as one of the proximate causes, of the injury must be alleged.”

It is alleged that, on the occasion of his injury, plaintiff dug and *362 scooped dirt, raised the bucket to a position approximately level with the top of the radiator, then backed the Loader towards a point where trucks were to be loaded. How far had he backed the Loader before he was thrown from the operator’s seat? When thrown from the operator’s seat, was plaintiff backing the Loader on level ground or up or down an embankment or incline? Plaintiff’s allegations' provide no answers. Obviously, when the Loader tilted forward it was not properly balanced. But no facts are. alleged as to defects in the design, materials or construction of the Loader causing it to be improperly balanced when in use under normal operating conditions for the purposes' for which it was designed.

It is alleged that, on the occasion of his injury, plaintiff raised the bucket, then filled or partly filled with dirt, to a position approximately level with the radiator, so that the bucket “could be driven’.’ to the left or right, and kept it in this position while backing the Loader until the time the Loader tilted forward. In the light of these allegations, the only reasonable meaning to be given plaintiff’s allegation that the bucket raised and lowered “without manual activation or operation” is that plaintiff did not, by manipulation of a lever or similar mechanical device, cause such movement. But no facts are alleged as to defects in the design, materials or construction of the mechanism for the raising and lowering of the bucket that would cause the bucket to- raise or lower unless the lever or similar mechanical device was manipulated intentionally or accidentally struck. Plaintiff alleges “the rear end of said loader suddenly and without manual activation raised itself from the ground and . tilted forward, thereby throwing (him) from his seat on said loader to the hood covering the motor of the loader,” and “immediately before and as (he) was thrown onto the hood . . . the bucket . . . was raising and lowering itself automatically and without manual activation or operation on the part of the plaintiff.”

. Analysis of the complaint impels the conclusion that the allegations to the effect the Loader was improperly balanced must be considered a mere conclusion of the pleader in the absence of factual allegations as to what defects, if any, in the design, materials or construction caused it to tilt forward on the occasion of plaintiff’s injury. As to the allegations that the bucket raised and lowered itself on the occasion of plaintiff’s injury “without manual activation or operation”: It is questionable whether the facts alleged are sufficient to show this was a proximate cause of the tilting forward of the Loader or an accidental result thereof. Be that as it may, the fact the bucket raised and lowered “without manual activation or operation” on the *363 occasion of plaintiff’s injury, absent factual allegations as to defects in the design, materials or construction thereof causing it to so act, is insufficient basis for plaintiff’s conclusion that defendant was negligent in this respect.

The doctrine of res ipsa loquitur does not apply “when the instrumentality causing the injury is not under the exclusive control or management of the defendant.” Smith v. Oil Corp., 239 N.C. 360, 367, 79 S.E. 2d 880.

Since the factual allegations of the complaint are insufficient to show plaintiff’s injury was proximately caused by the negligence of defendant, the judgment of the court below is affirmed.

Affirmed.
