Dissection of a Case of Hydrocephalus intermis, 363 



The effect of silex in various cases is the same as an acid, 

 and in some situations, where an acid or acid properties 

 really exist, no other cause is present. All acids we know

 property. It is, however, a strong support to this question 

 to see my idea of its general acid quality corroborateilr by 

 others, for it has lately been observed, (Journal des Mines, 

 tome XX. p. 245.) that " in the analysis of ores, silex acts 

 very sensiidy as an acid.'*

 the head was large, and that it was probable there was water 

 contained in the brain. The child grew, and enjoyed good 

 health till the 1 7th month after birth ; but the head continued 

 large. He was then seized with the hooping-cough, which was 

 very violent, and he lost his sight for some time. It was now 

 pronounced decidedly, to be a case of hydrocephalus internus. 

 On his recovering from the hooping-cough he regained 

 his sight and strength, so as to enable him to walk with tlie 

 hand of his nurse, or in a^ go-cart : his appetite was goody
