This analysis bears out the result of the investigation of the 

 blood, given in Vol. I., page 326. 



Landerer 1 has analysed the faecal evacuations of a child suf- 

 fering from diarrhoea infantilis. It was a yellow fluid, with an acid 

 and bitter taste, and its specific gravity was 1038*2. Landerer 

 found in it : carbonate of lime T50; phosphate of lime 2-00; 

 chloride of calcium 1-50; chloride of magnesium 2'45; chloride 

 of sodium 2'43; sulphate of lime T50; sulphate of magnesia O80; 

 bilin, butyric acid, and extractive matter 3*00; spirit-extract I'OO; 

 free lactic and hydrochloric acids 1*00. 



In enterophthisis, the faecal evacuations likewise separate into 

 two strata the lower is flocculent, and when examined under the 

 microscope is seen to consist of mucus- or pus-corpuscles min- 

 gled with remnants of food, or with an amorphous mass tinged 

 with pigment. Sometimes we find, in the deposit from these 

 evacuations, small white or yellow masses, which consist of 

 cells, and can be easily crushed (such as I have already de- 

 scribed in speaking of the evacuations in typhus), and mixed 

 with them there are numerous fat-vesicles. A little blood is 

 not unfrequently observed in these stools ; they then have a 

 chocolate or dark blood-red tint. The supernatant fluid is 

 turbid, and of a yellow, brown, or bloody tint ; it always con- 

 tains a considerable amount of albumen. 



In icterus the faeces are generally devoid of all the consti- 

 tuents of the bile : they are consequently of a white or grayish 

 white colour; they are usually very firm, and deficient in 

 moisture. 



[I am indebted to Dr. Percy for the following ultimate 

 analysis of the faeces in jaundice.
