Ligation of the Thyroid Arteries. 



213 



Glycosuria from April 11 to April 17. Ligation of superior and 

 inferior arteries on the left side April 17. Sugar positive April 

 18. Dog died on the following day from a severe attack of tetany. 

 No autopsy. Course: animal was in perfectly good condition 

 until the day following the second ligation. There was a strong 

 ferric-chlorid reaction in his urine on the third day after pan- 

 createctomy. There was no diacetic-acid reaction on succeeding 

 days. 



Table I. — Bloodsugar estimations were made in these animals 

 before the pancreatectomies. They were starved at least 24 

 hours preceding the operation. The highest figure obtained 104 

 mmgr. per 100 c.c. blood in 3 dogs in whom estimations were 

 made during the hot summer months July and August. 



Table IT. — Dog 124 was glycosuric throughout after pancrea- 

 tectomy, but there was no increase in the contents of bloodsugar. 

 Dog 123 after almost complete pancreatectomy (a minute rem- 

 nant of pancreas was found at autopsy) did not develop glycosuria 

 while under observation for 26 days. His original weight was 

 1 1.2 kilos. On the last day of observation his weight was 9.7 

 kilos, when he was disposed of with chloroform (loss of approxi-
