OSMIC CONFIRMATION OF METHOD. 



Several capillary loops from choroid plexus of the Ihird ventricle 

 from dog shell-shocked 9 (afler being stained wilh Sudan III) taken 

 and Ireated wilh few drops of Ogmic Acid (2 p. 100 solution). Droplets 

 already stained wilh Sudan III now slain black with Osmic Acid. 



Examir,ation of brams for fat dogs shell-shocked 3, 4, 7, 8 and 9 

 (Neuio-Surgical Laboratory numbersj. — Droplets slainable wilh 

 Sudan III found quite constantly in choroid plexuses — in the capil- 

 laries of thèse plexuses, both in shocked and control dogs. 



In dogs shell-shocked 8 and 9 Ihere is évidence ofperivascular drop- 

 lets in the dura {in corpus slriaium in dogs shell-shocked -4 and 8). 



In the dura of dogs shell-shocked 3 several small vessels are présent 

 filled with blood which shows partial staining with Sudan III ; free drop- 

 lets mixed wilh the blood and some bodies, perhaps erylhrocyles, taking 

 partially a Sudan III slain. Is Ihis évidence thaï after cr with for- 

 maldehyde fixation Ihe fat content of the vessels may be increased ? 

 May some corpuscles be in such a slate of fixation or degeneration that 

 falty substances are liberated stainable with Sudan III? 



Examinalion ofvisccra of dog shell-shocked 7 for fat. — Droplets 

 fourd in lung; but ail organs too poorly preserved to make any obser- 

 vations of value.

by J. Erlanger and Gasser. 



On April 18, 1918, we filcd wilh the Commitlee on Shock a report on 

 the ref-ultsoblained in the first few ca'^es of slandardized shock trealed 

 by the intravenus injection of certain solutions. Since then we hâve 

 bten accumulaling additional cases and now feel that the tesls hâve 

 been employed in a sufficienlly large number lo juslify another report, 

 although the experimenls are still being continued.
