SCARLET FEVER. " Coze and Feltz have found 

 in the blood of scarlet fever, taken from patients, 

 living or recently dead, some rods as well as mo- 

 bile points. This blood injected into the cellular 

 tissue of rabbits has sometimes produced death, 

 and the blood of the animals experimented upon 

 has presented the same bacteria as human blood 

 of scarlatina : they are simply a little larger and 

 longer. As to the mobile points, they appear to 

 correspond to the micrococcus of scarlatina de- 

 scribed by Hallier" (Magnin). Reiss found, in 

 blood drawn from a vein in the arm of a patient 

 dying of scarlet fever, that " the serum was filled 

 with an infinite number of small, rapidly oscillating 

 bodies, .which, under a magnifying power of five 

 hundred diameters, appeared as black points be- 

 tween the groups of blood corpuscles. In addition, 

 there were also rod-like formations, which at many 

 places were recognized as being composed of three 

 or four or more of these minute bodies disposed in 

 rows." Reiss injected a few drops of this blood 

 under the skin of the back of a rabbit, with the 

 effect of developing like small bodies in its blood, 

 and causing death in twenty-four hours. Further 

 inoculations with this rabbit's blood gave rise to 

 identical results. 1 In the experiments of Coze 

 and Feltz, the introduction of a small quantity of
