No changes were observed in Auerbach's or Meissner's plexi in 

 the intestine itself. Comparing with the symptoms of Addison's dis- 

 ease it appears that the characteristic visceral pains of that disease 

 might be due to disease of the ganglia coeliaca, the same is true of 

 the digestive disturbances, but the color changes characteristic of the 

 disease are not reproduced by injury to the ganglion. The anorexia 

 of Addison's disease is not produced by injury. The aceturia some- 

 times observed is incidental. 



The Nerves of the Heart of the Crayfish. 1 



In a communication largely occupied with citation of literature 

 and dealing with the vertebrate heart the author describes the ganglia 

 of the crustacean heart. 



He finds a continuous chain of ganglion cells the full length of 

 the heart, which fall chiefly into two groups, an anterior and posterior. 

 In addition there are other scattered cells. The cells vary in size and 

 form, being unipolar and multipolar, with branching processes extend- 

 ing among the muscles. 



The nerve fibres anastomose much as in the nerves of the 

 mammalian heart. The muscles of the heart are said to be devoid of 

 nuclei. 



The presence of these cells explains the long continued activity 

 .of the heart after removal. The histological results were obtained 

 with gold chlorid. The parts of the opened heart were expanded and 

 treated with 20 % formic acid for 3 to 5 minutes, then, after washing 

 in water, with 2 c / gold chlorid for 5 to 20 minutes and left in 20 % 

 formic acid 12 hours. Two excellent plates accompany the paper. 

 The comparisons with the vertebrate heart seem a little forced. 



Orbital Nervous System of the Rabbit. 2 



Detailed anatomical descriptions, tables and illustrations of the 

 nervous connections within the orbital cavity. The ciliary ganglion 

 was extirpated with the following results : Expansion of the pupil, 

 paralysis of accomodation and pupil-reflexes, and considerable dimu- 

 nition of the tension of the eye-ball at first. The unoperated eye 

 either remained normal or exhibited myosis, hyperemia of the iris, 

 and peri-corneal injection.
