Note by D. Noel Paton. 
Dr M‘Lachlan having been compelled to abandon the investiga- 
tion, I thought it well to determine the influence of feeding with 
lymphatic glands upon the production of allantoin. The 
abdominal lymphatics of the ox, freed from fat, were used. When 
given to the setter used in the previous experiments, they were 
vomited, and when next given, the dog refused to eat them. 
A fox terrier, weighing about 6 kilos, was consequently used. 
As I found it difficult to be sure that the ammonia is entirely 
got rid of from the silver allantoin precipitate by the method em- 
ployed by Dr M ‘Lachlan, I adopted the plan of passing a current 
of air through the Erlenmeyer’s flask, kept at 60° C. for several 
hours, till no change was produced on a piece of wet red litmus 
paper held in the flask. 
The following results were obtained : — 
Urine of 
Total N. per 
cent. 
Allantoin N.

Allantoin N.

It would thus seem that the administration of lymph glands 
causes an increase in the allantoin of the urine very little greater 
than that caused by feeding with pancreas, and that its effect is 
much smaller than that produced by thymus feeding.
