J BUFORD v. cook. 21 It is not necessary that the language of the certificate be identical with that of the form given by the statute. It is only necessary that it con- forms to it in eifect. The certificate under consideration conforms to the form in the statute in all the necessary elements, and this is all that is required. " It is a substantial compliance in everything material." See Tod v. Baylor, 4 Leigh, 513; Siler v. McOlanach
