Fluid of pemphigus. I have examined the faintly yellow 

 fluid occurring in the bullse of pemphigus. It had an acid 

 reaction, and deposited a sediment of corpuscles resembling 

 mucus- or pus-corpuscles in form, and in which a nucleus was 

 very apparent. Its specific gravity was 1018. On evaporation 

 it developed an acid odour similar to that which is observed 

 on evaporating the saliva in cases of ptyalism and due to the 

 presence of a little acetic acid. When submitted to a high 

 temperature it deposited a quantity of very white albumen; 

 the acid reaction was then more powerful than before, but 

 after evaporation to dryness it disappeared, for the alcohol with 

 which the residue was extracted had scarcely a perceptibly acid 

 reaction. It was composed of :

Five years afterwards I examined the fluid from the same 

 patient during a fresh attack. In its physical characters it 

 was much as before.
