concentrated. There is, therefore, greater danger of poisoning 
. in patients severely ill. Doses of iodine which have been ac¬ 
companied by no unfavorable complications in mild cases have 
produced iodism in individual cases when seriously affected. 
The infusion has produced a check in the milk flow but in the 
course of a few days it has acquired its normal volume again. 
The yield of milk noted in certain cases was attained on a re¬ 
stricted diet. The potassium iodide and air infusion has not 
produced in any case untoward affects upon the udder nor upon 
the quality of the milk. Boiled water has constantly been used 
for the Solution. For use, the temperature had best be 40-42° C., 
so that after its infusion into the udder it shall still have a some¬ 
what higher temperature than the milk in the udder. Through 
a relatively high temperature of the solution it loses its specific 
weight and can in that way be in better condition to penetrate 
the alveoli. If the water is boiled immediately before the pa¬ 
tient is attended, and poured, almost boiling hot, into a bottle 
and this immediately wrapped in several thicknesses of paper, 
the solution can still be burning hot when unwrapped an hour 
later. The milking out before the infusion, and the hourly 
massage after the same must as far as possible be carried out. A 
small volume of air should, where possible be forced into 
each gland more at the beginning than at the close of the 
infusion. 
Where the disease threatens to run a very rapid course it 
would perhaps be well to try to stimulate the action of the 
heart at once and to increase the arterial blood pressure by 
means of intravenous injections of physiological salt solution 
(0.5 or 0.6 per cent.). I have however hesitated to apply this 
in the usually overcrowded cow stall; a subcutaneous solution 
of several liters of salt solution is not practicable. For this 
reason, since my attention has been particularly directed to the 
cardiac paralysis, I have come to rely chiefly upon subcutaneous 
injections of camphor, coffee, and especially caffein-injections. 
The first agent I have used, in view of the possibility of slaugh¬ 
ter, only upon the owner’s consent. The caffein has shown in
