teries, or some other remedy, should constantly be sought which 
acting on a similar line and comparatively neutral, which hy 
infusion into the udder acts more directly upon milk fever. 
I therefore regard the study from the standpoint of treat¬ 
ment of the disease as by no means completed, but very much 
hope that it can be improved. I not merely expect, but hope, 
that very much must be changed in, and very much added to^ 
these, my theoretical studies, especially from the physiological 
and chemical sides ; for our knowledge in relation to the break¬ 
ing down of tissues and body fluids, and especially the products 
of tissue change occurring in certain organs under ordinary con¬ 
ditions and the import of these, to the entire organism is, un¬ 
fortunately, as yet very imperfect. I hope, therefore, that this 
work of mine can serve as a preliminary basis for further re¬ 
search, which, besides chemical observations, must at the same 
time rest upon physiological and chemical foundations. 
When I presented a report at a meeting of veterinarians in 
Copenhagen in the autumn of 1897, upon the cause and treat¬ 
ment of parturient paresis, instructor C. O. Jensen proposed a 
collection of the data upon the results of the potassium iodide 
treatment. He also announced his willingness to undertake 
the work. 
In the January number of the Maanedsskrift for Dry lager 
there is presented a summary of the data thus obtained. Reports 
from 65 veterinarians are included. The report comprises in 
all 412 cases of calf fever, which were treated with potassium 
solution infusions in the udder, including therein the 50 cases 
already mentioned by me. Besides 5 patients were treated with 
subcutaneous injections of iodine. Of these five cases three 
ended fatally. Of the 412 cases about 90 per cent, recovered 
from the calf fever, while later 3.88 per cent, of these died or 
were destroyed on account of inhalation pneumonia and metritis. 
Regarding the course, details accompany the reports of 288 
patients. Of these 249 got up iii the first 24 hours after the 
beginning of the treatment, and. indeed, 27 after 1-6 hours, 135 
after 6-12, 52 in 12-18, 35 after 18-24, 18 after 24-36, ii after
