(1054) Qui periculum amat in eo peribit: He who loves danger will perish by it. Qui potest et debet vetare, jubet (Gilb. 35): He who is able and ought to forbid, commands. Qui primum peccat ille facit rixam (Godb.): He who sins first, makes the strife. Qui prior est tempore potior est jure (Co. Litt. 14a): He who is first in point of time is preferred in law. (See Brace v. Duchess of Marlborough, 2 P. Wms. 49, 1, and Marsh v. Lee, 1 White & T. Lead. Cas. 659.) A mortgagee may recover in ejectment without giving notice to quit against a tenant who claims under a lease from the mortgagor, granted after the mortgage without the privity of the mortgagee. The rule stated in this maxim applies as between finders of "treasure trove," derelicts, and such like. (See, also, Keech v. Hall, 1 Sm. Lead. Cas. 574.) Where several persons have interests in one property, and equal equities in every point except time, as in the case of a third mortgagee who had no notice of a second mortgage when making his advance, here both mortgagees have equal equities, but the second mortgagee being first in point of time, has the prior right in this instance, however, the third mortgagee could avail himself of the advantages of tacking. Qui pro me aliquid facit, mihi fecisse videtur (2 Inst. 501): He who does anything for me, appears to do it to me. Qui providet sibi providet hæredibus: He who provides for himself, provides for his heirs. Qui rationem in omnibus quærunt, rationem subvertunt (2 Co. 75): They who seek a reason for everything, subvert reason. Qui semel actionem renunciaverit amplius repetere non potest (8 Co. 59): He who renounces an action once, cannot any more repeat it. Qui semel est malus, semper præsumitur esse malus in eodem genere (Cro. Car. 317): He who is once criminal, is presumed to be always criminal in the same way. Qui sentit commodum sentire debet et onus (1 Co. 99): He who receives the advantage ought also to suffer the burden. Equity always acted on this principle when enforcing contribution between co-sureties. Dering v. Earl of Winchelsea, 1 White & T. Lead. Cas. 106, and Waugh v. Carver, 1 Sm. Lead. Cas. 908. Qui sentit onus, sentire debet et commodum (1 Co. 99a): He who bears the burden of a thing, ought also to experience the advantage arising from it. Qui tacet, consentire videtur (Jenk. Cent. 32): He who is silent, appears to consent. Qui tacet consentire videtur, ubi tractatur de ejus commodo (9 Mod. 38): He who is silent is considered as assenting, when his advantage is debated,
