 not need an interpolant, try the `Feagin12` or `Feagin14` methods. Note that the
 Feagin methods are the only high-order optimized methods which do not include a
 high-order interpolant (they do include a 3rd order Hermite interpolation if
-needed).Note that these high order RK methods are more robust than the high order
+needed). Note that these high order RK methods are more robust than the high order
 Adams-Bashforth methods to discontinuities and achieve very high precision, and
 are much more efficient than the extrapolation methods. However, the `CVODE_Adams`
 method can be a good choice for high accuracy when the system of equations is
