a peculiar form of endemic ophthalmia recently prevalent at 

 Berlin. 



1. In a case of ophthalmia of two days' standing, accom- 

 panied with much chemosis, the specific gravity of the blood 

 was 1051. The specific gravity of the serum was 1027, and 

 of the clot 1086. 



In 1000 parts there were : 



Water .... 798-0 



Solid constituents ; . . 202-0 



Fibrin . . . .2-0 



Blood-corpuscles . . . 117-5 



Solid residue of serum . . 82-5 



The serum was of a blueish-red colour and opaque. 



2. The blood drawn from a patient on the third day of the 

 ophthalmia had a specific gravity of 1052. The specific gravity 

 of the serum was 1028 and of the clot 1090. 



In 1000 parts there were : 



Water .... 795-0 



Solid residue . . . 205-0 



Fibrin . . . .2-0 



Blood-corpuscles . . . 115-1 



Solid residue of serum 87'9 



3. A patient on the second day of the disease yielded blood 

 of specific gravity 1055. The specific gravity of the serum was 

 1030, and of the clot 1092. 



In 1000 parts there were contained :

4. In a similar case the blood had a specific gravity of 1054. 

 The specific gravity of the serum was 1035, and of the clot 

 1088.
