lated by Cannon. 1 In the second place, however, the existence of 

 adrenalin in the blood stream is apparently necessary for the 

 maintenance of vasomotor tone itself. The rapid exhaustion of 

 the available supply of adrenalin in the blood stream, obtainable 

 in these experiments appears the factor responsible for the early 

 breakdown of the vasomotor system. Elliott 2 has argued for such 

 a function of adrenalin from evidence of a different character. 



Finally the entire evidence of these studies points to a complete 

 dependence on the functional conductivity in the brain stem of 

 both the initiation of the vasomotor effects by the splanchnics, 

 and the increased secretion of adrenalin through which it is 

 maintained. In conditions of the animal when no other responses 

 of the brain stem are being conducted, the vasomotor response 

 also fails to appear.

Preliminary report on a typhoid bacteriophage.

1 would like to report briefly on a lytic principle isolated by 

 the d'Herelle technique from the stool of a typhoid convalescent, 

 kindly sent to me by the Research Laboratory of the Health 

 Department. A small particle of feces was emulsified in broth 

 and incubated overnight. The next day about twice the volume 

 of broth was added and the emulsion was centrifuged and filtered 

 through a Berkfeld. The original filtrate was both inhibitory and 

 lytic, that is, a small amount of the filtrate added to a tube of 

 broth would, in spite of heavy inoculation with the homologous 

 typhoid strain, prevent growth, and young turbid broth cultures 

 became transparent on the addition of small quantities of the 

 filtrate. The lytic principle could then be transmitted in series 

 from both the inhibited and the dissolved cultures.
