304 CIRCULATING FLUIDS: 



to the violence of the attack, as is seen in the third case, where 

 the fibrin is only slightly diminished^ although the corpuscles 

 are considerably increased. 



Consciousness remained in the fourth and fifth cases. The 

 increase of the fibrin, while the corpuscles remained stationary, 

 is deserving of notice in the former of these cases. In the sixth 

 case the hemorrhage had occurred three weeks before the vene- 

 section, and was followed by entire hemiplegia of the left side. 

 In the seventh case the patient had previously been bled on the 

 third day of the attack ; she had retained her consciousness. 



Andral and Gavarret have made 21 analyses of the blood of 

 15 persons sufl"ering from cerebral congestion (the usual pro- 

 dromus of spontaneous cerebral hemorrhage). Its symptoms 

 are intense headache, giddiness, and a tendency towards epistaxis. 



In the majority of these cases the fibrin was found to be below 

 the normal quantity. It twice rose to 3' 7, once to 3 '5, and once 

 to 3*3 ; in all the other cases it was below the normal amount, 

 and it occurred as low as 1-6. 



The amount of blood-corpuscles was pretty near the standard 

 average ; in two instances it rose to 152 and 154 ; and in two 

 other cases, (the one a woman of weakly condition, and the 

 other a person under the noxious influence of lead,) it fell to 88. 



I shall only give the maxima, minima, and mean of these 

 researches : 



Water. Solid constituents. Fibrin. Blood-corpuscles. Residue of serum. 

 Maximum . 820-3 259-8 3-7 



Minimum . 740-2 179'7 1-6 



Mean . . 787-1 212-9 2-6 



Healthy blood 790-0 210-0 3-0 



The residue of the serum contained, on an average, 7*9JJ of in- 

 organic constituents, the same amount as in cerebral hemorrhage. 



No causes can be assigned with any degree of certainty to 

 the peculiar modification of the blood to which I have assigned 

 the term hypinosis. 



the amount of fibrin, since the corpuscles are insoluble in defibrinated serum, pro- 

 vided a sufficient amount of chloride of sodium be contained in it. On the other 

 hand, the solubility of the haematoglobulin in the liquor sanguinis and its consequent 

 property of escaping through the walls of the vessels may arise from an al)solute de- 

 crease of salts or from an increased amount of water in the 1)lood. Ju the analyses 

 quoted in the text the salts were not diminished.
