DIARRHOEAS OR “ SCOURS” OF NURSLINGS. 411 
house, or otherwise rapidly and artificially cooled, in order to 
suspend further digestive action. It should be used before 
many hours have elapsed, as it does not keep long; or, better 
yet, made fresh as required. When farinaceous additions are 
to be made, if roasted, they are best stirred in the milk when 
the latter is warm. Another equally good plan, one by which 
the roasting is avoided, is to make into thick gruel by boiling, 
subsequently thinning one-half, and adding to the peptonized 
milk in the proportion of one to four or eight of the latter. 
“ Pure pancreatin,” so called, is a misnomer, since that which 
is sold under the name is simply a highly concentrated pre¬ 
paration containing the various digestive ferments of the pan 
creatic secretion; such title is of empiric origin. I give the 
preference to Parke, Davis & Co’s pancreatin, because of its 
definite, known strength, five grains of which, with a scruple 
of soda in half an hour completely peptonizes a pint of milk 
at a temperature of from iio° to 115 ° Fhr. If such propor¬ 
tion of pancreatin to milk fails to peptonize, it is prima facie 
evidence of the utter worthlessness of the ferment employed. 
Heat is not necessarily a concomitant of the pancreatizing 
process ; if preferred (and it is sometimes advisable), the milk 
may be diluted with half its volume of lime water, pancrea¬ 
tin being added in the proportions above given, and the mix¬ 
ture allowed to stand for three or four hours at an ordinary 
temperature, occasionally stirred. Peptonized milk, however, 
must not be considered as meeting all this indications of treat¬ 
ment in all cases of scours, for such, far from being a remedy, 
is oft-times of value chiefly as a food that can always be made 
of like quality, and administered in such quantity and frequen¬ 
cy as the individual case demands ; on this account it is more 
nourishing than milk from the maternal udder, and much more 
acceptable to irritated and inflamed digestive tracts. 
Pepsin, when administered, should follow the food by 
perhaps thirty minutes, and is often advantageously given in 
a little weakly acidulated fluid, since there are several pecu¬ 
liarities in the action of remedies upon ruminants (more es¬ 
pecially adults), chiefly referrable to the construction of the 
stomach in four divisions, only the last one of which (aboma-
