My experiments up to the present time have shown that 

 marked rise in blood pressure occurred on stimulating Meynert's 

 reflex bundle, the median nucleus, the fornix and the anterior 

 commissure. This rise has been, with but one exception, accom- 

 panied by a slowing of respiration or apnoea. The lateral part 

 of the thalamus yielded slight, if any, changes in blood pressure. 



Changes in spleen volume, with but two exceptions, have never 

 occurred independently of changes in blood pressure. Usually 

 the spleen volume was increased when the blood pressure rose, 

 though on several occasions it fell. 



In the anterior corpus quadrigeminum I have several times 

 obtained changes in respiration without changes in blood pressure. 



These facts bring out two important points. First of all, that 

 the marked blood pressure changes occur particularly when stimu- 

 lating the median portion of the thalamus, particularly the ol- 

 factory system, somewhere in its course, and as this is highly 

 developed in the Carnivora, it seems most probable that we are 

 dealing here with phenomena following the introduction of strong 

 sensory stimuli rather than independent centers. 



Secondly, what is the primary factor in these changes? Are 

 the changes in blood pressure and in spleen volume secondary to 

 respirators" changes or are they phenomena occurring at the same 

 time as, but independent of, the respiratory change? On this 

 point further work is necessary before a positive opinion can be 

 expressed.

The influence of oils and of lecithin on the protein metabolism.

Experiments intended to determine the influence of different 

 quantities of vegetable oils, like olive oil, cotton-seed oil, and 

 peanut oil, on the metabolic processes, when injected subcutane- 

 ously, have been performed on dogs and rabbits. One experiment 

 on an otherwise fasting dog is presented herewith. The oil given 

 in this case was cotton-seed oil put into the form of a very fine
