CAUTIONER, Scotch law, contracts. One who becomes bound as caution or surety for another, for the performance of any obligation or contract contained in a deed.

CAVEAT, practice. That hebeware. Caveat is the name of a notice given by a party having an interest, to some officer, not to do an act, till the party giving the notice shall have been heard; as, a caveat to the register of wills, or judge of probate, not to permit a will to be proved, or not to grant letters of administration, until the party shall have been heard. A caveat is also frequently made to prevent a patent for inventions being issued. 1 Bouv. Inst. 71, 534; 1 Burn's Ecc. Law, 19, 263; Bac. Abr. Executors and Administrators, E 8; 3 Bl. Com. 246; Proctor's Pract. 68; 3 Bin. Rep. 314; 1 Siderf. 371 Poph. 133; Godolph. Orph. Leg. 258; 2 Brownl. 119; 2 Fonbl. Eq. book 4, pt. 2, c. 1, 3; Ayl. Parer. 145 Nelson's Ab. h. t.; Dane's Ab. c. 223, a. 15, 2, and a. 8, 22. See 2 Chit. Pr. 502, note b, for a form.

CAVEAT EMPTOR. Let the purchaser take heed; that is, let him see to it, that the title he is buying is good. This is a rule of the common law, applicable to the sale and purchase of lands and other real estate. If the purchaser pay the consideration money, he cannot, as a general rule, recover it back after the deed has been executed; except in cases of fraud, or by force of some covenant in the deed which has been broken. The purchaser,if he fears a defect of title, has it in his power to protect himself by proper covenants, and if he fails to do so, the law provides for him no remedy. Cro. Jac. 197; 1 Salk. 211 Doug. 630, 654; 1 Serg. & R. 52, 53 , 445. This rule is discussed with ability in Rawle on Covenants for Title, p. 458, et seq. c. 13, and the leading authorities collected. See also 2 Kent, Com. Lect. 39, p. 478; 2 Bl. Com. 451; 1 Stor , Eq. 212 6 Ves. 678; 10 Ves. 505; 3 Cranch, 270; 2 Day, R. 128; Sugd. Vend. 221 1 Bouv. Inst. n. 954-5.

2. This rule has been severely assailed, as being the instrument of falsehood and fraud; but it is too well established to be disregarded. Coop., Just. 611, n. See 8 Watts, 308, 309.

CAVIL. Sophism, subtlety. Cavilis a captious argument, by which a conclusion evidently false, is drawn from a principle evidently true: Ea est natura cavillationis ut ab evidenter veris, per brevissimas mutationes disputatio, ad ea quce evidentur falsa sunt perducatur. Dig. 60, 16, 177 et 233; Id. 17, 65; Id. 33, 2, 88 .

CAESARIAN OPERATION, med. juris. An incision made through the parietes of the abdomen and uterus to extract the foetus. It is said that Julius Caesar was born in this manner. When the child is cut out after the death of the mother, his coming into being in this way confers on other persons none of the rights to which they would have been entitled if he had been born, in the usual course of nature, during her life. For example, his father would not be tenant by the curtesy; for to create that title, it ought to begin by the birth of issue arive, and be consummated by the death of the wife. 8 Co. Rep. 35; 2 Bl. Com. 128 Co. Litt. 29 b.; 1 Beck's Med. Jur. 264 Coop. Med. Jur. 7; 1 Fodere, Med. Leg. 334. The rule of the civil law on this subject will be found in Dig. lib. 50, t. 16, 1. 132 et 141; lib. 5, t. 2, 1. 6; lib. 28, t. 2, 1. 12.
