In Gudwallen, investigations were also made with Lorenz’s 
serum and with tallianine, the results of which are also briefly 
given here. The results at this stud are given by the veter¬ 
inarian in charge, Dr. Puschke, as follows: 
The lung plague broke out among the stallions in the royal 
breeding stud at Gudwallen, July 9, 1911. The first to be at¬ 
tacked was a young stallion purchased in the spring, and the 
second followed in fourteen days. The total number attacked 
up to October 21 was 91, and one died August 11. 
The stallion first attacked had a severe bilateral pleuro-pneu- 
monia, and was treated exclusively with cold compresses to the 
chest. The disease pursued the normal course and in eight days 
the horse was free from fever. One week later he developed a 
tenosynovitis in both fore feet and was very lame. Since early 
in September he has been on the mend. Twelve stallions were 
also treated with the Lorenz lung plague streptococcus serum. 
Up to 450 c.c. serum was injected. The latter exerted no in¬ 
fluence on the fever. In three animals the lungs remained sound, 
but in the others a slight pneumonia could be recognized. 
With tallianine twelve stallions were treated. The quantity 
injected per animal was up to 130 c.c. The serum had no in¬ 
fluence on the fever, which lasted on an average eight days. Only 
three animals developed pneumonia, and one of these died 
August 11 (see above). 
There were treated with salvarsan sixty-five horses. In 
fifty-five a single injection of 3 grams was sufficient, and the 
animals were free from fever in five days at the outside. In 
ten animals a second injection was necessary—2 grams on the 
fifth day—and they were free from fever by the eighth day of 
the disease. There were no unpleasant collateral effects of sal- 
versan of any sort. In all the animals the lungs and heart re¬ 
mained sound. It is to be noted especially that these animals 
who received salvarsan made very quick recoveries. 
An oil emulsion of salvarsan, joha, was applied in three cases. 
The first stallion had been treated already with tallianine and 
on the eighth day was almost free from fever. On the ninth 
day the temperature again rose, whereupon 7.5 c.c. joha (= 3 
grams of salvarsan) were injected into the muscles of a hind 
leg. On the next day the temperature was normal. The second 
stallion received 7.5 c.c. twice but without influence on the fever. 
At the injection point arose a small, firm, tender swelling. The 
third stallion likewise received 7.5 c.c. joha. As this likewise
