 but no true (.lumpinfi". This is sonuliiiU's mistaken for a 

 re-aetion. A^^-ain. dissohed blood alw a\s shows a varying- 

 amount of detritus, jiartlv in the form of tibi-inous ehimjis, 

 and j)rolon>i;-ed micr()sc(j])ioal examination of the mixture of 

 disolved f)loo(l with a culture fluid shows that the 1)aeilli 

 often become entangled in these c]um])s. and in thecoui'se 

 of one-half to one hour \erv few isolated motile bacteria 

 arc seen. The fibrinous clumps, es])ecially if examined 

 with a poor lig"ht, mav be very easily mistaken for clumps 

 of bacilli. This pseudo-re-action is reg"arded by many in- 

 experienced obseryers as a true typhoid re-action, but it 

 occurs as readily with non-t\phoid as with typhoid blood.
