 of PhysioL, Bd. XL VI, Heft 3, S. 285—290, 1913. 



Section of the splanchnic nerves causes degeneration of the myelinated 

 nerves of the adrenal glands up to their endings in the raedulla. No true gang- 

 lion cells are found in the medulla: the meduUary cells (paraganghon cells) 

 are on the same level as the cells of a sympathetic ganglion. Min es. 



469) Miiies, (x. B., On functional analysis by the action of electroly- 

 tes. In: Journ. of PhysioL, Bd. XL VI, S. 188, 1913. 



Experiments on the electrical and mechanical responses of the frog's heart 

 perfused with various Solutions. Füll details of the technique employed are 

 given. The electrograms obtained are of value in permitting exact measurenents 

 of the A — V interval and of the duration of the excited State in the ventricle. 

 The general question of the form of the electrogram is discussed. By changes 

 in the hydrogen ion concentration and in the concentration of calcium ions in 

 the perfusion fluid various points in functional analysis of the heart are demon- 

 strated. Autorreferat. 



470) Barry, D. T., Afferent impressions from the respiratory me- 

 chanism. In: Journ. of Physiol, Bd. XLV, S. 473, 1913. 



Experiments on rabbits and cats, made by blocking the trachea in various 

 phases of the respiratory movements with and without section of the vagi and 

 extirpation of the stellate ganglia. The author concludes that during ordinary 

 respiration inspiratory impulses arise in the thoracic walls and travel by soma- 

 tic nerves and by the spinal cord to the respiratory centre. Inspiratory impulses 

 of visceral origin pass probably through the stellate ganglion. The vagus con- 

 veys expiratory impulses of visceral origin. Min es.

 wards sugar. In: Journ. of Physiol., Bd. XLV, S. 470, 1913. 



Confirmatory of the work of Knowlton and Starling. The heart of the depan- 

 creatised dog loses its power of consuming sugar. This power can sometimes be restored 

 by perfusion with pancreatic extract. Minei?.

 The action of calcium salts in the generation of trypsin from trypsino- 

 gen. In: Journ. of PhysioL, Bd. XLVL S. 159, 1913. 



Pancreatic juice always contains entero-kinase. The addition of calcium, Strontium 

 or barium salts allows the activation of trypsiuogeii by this kinase to proceed because 

 it diminishes the alkalinity of the juice, by precipitating carbonates. Min es. 



473) Matsuo, I., On the secretion of pancreatic juice. In: Journ. of Phy- 

 sioL, Bd. XLV, S. 447, 1913. 



The author confirms the results of Bayliss and Starling on the production 

 of secretin in the duodenum. When acid is introduced into the duodenum, se- 

 cretin is poured into the gut as well as into the blood. Cross-circulation experi- 

 ments give irrefutable proof of the chemical nature of the mechanism involved 

 in "acid secretion". Secretin is not absorbed from the lumen of the gut; it is 

 inactive if administered hypodermically. Secretin is not identical with "vaso- 

 dilatin" as has been maintained byPopielski. Mines. 



474) Nikiforowsky, P. M., On depressor fibres in the vagus of the frog. In: 

 Journ. of PhysioL, Bd. XLV, S. 459, 1913. 



The vagus nerve in the frog contains depressor fibres: their development is less 

 than in the mammal. Mines.
