A personal service, but due only by reason of lands which were held in fee. Bract. 1. 2, c. xvi. SERVITIUM FORINSECUM.-A serwho were sent abroad with writs, &c., to summon persons to that court. 2 Hen. IV. c. 23. SERVITUDE, in its original and popular sense, signifies the duty of service, or rather the condition of one who is liable to the performance of services. The word, however, in its legal sense, is applied figuratively to things. When the freedom of ownership in land is fettered or restricted, by reason of some person, other than the owner thereof, having some right therein, the land is said to serve such person; the restricted condition of the ownership, or the right which forms the subjectmatter of the restriction, is termed a "servitude;" and the land so burdened with another's right is termed a "servient tenement," while the land belonging to the person enjoying the right is called the "dominant tenement." The word "servitude" may be said to have both a positive and a negative signification: in the former vice which did not belong to the chief lord, but sense denoting the restrictive right belongto the king. Mon. Ang. ii. 48. Servitium, in lege Angliæ, regulariter accipitur pro servitio quod per tenentes dominis suis debetur ratione feodi sui (Co. Litt. 65): Service, by the law of England, means the service which is due from the tenants to the lords, by reason of their fee. SERVITIUM INTRINSECUM.-That service which was due to the chief lord alone from his tenants within his manor. Fleta 1. 3.
