in two quarts of warm gruel, made either of flour or oatmeal, or in 
the same quantity of linseed-tea. 
Should the before-mentioned symptoms increase in severity, 
the beast become more spiritless, cough and heaving at the flank

an uncontrollable nature as we have sometimes observed in the 
horse, when the smallest dose would produce this effect: it should 
be combined with opium to guard its action upon the bowels, and 
given in thick gruel, as in the following form : —

mixed in two quarts of gruel, to which half a pint of porter or ale
