210 VEGETABLE PARASITES. 



oris are nothing more than such an epithelial productiveness on a 

 larger scale. 



3. Stomatitis follicularis occurs most frequently about the time 

 of the first teething and in old age. Large, white, discrete, 

 half-spherical or flat vesicles %re formed especially on the lips, 

 on the inner side of the cheek, and on the gums. These vesicles 

 are depressed in the middle, often provided with a point ; they 

 burst soon, forming superficial ulcers with a red ring, and healing 

 sometimes with and sometimes without cicatrization. Weak 

 children are most subject to these ulcers, and in them they pene- 

 trate deeper, spread out more, possess a lardaceous base, and 

 cause greater destruction. These vesicles are nothing more than 

 the inflamed and enlarged mucous follicles. 



4. It is not very likely that the thrush should be confounded 

 with the fatty degeneration of the villi of the mucous membrane, 

 especially near the cardia, observed by Reubold, which I stated 

 often to occur normally in the intestinal canal of dogs, and which 

 I regard as a sign of old age. 



5. The gastric fur of the tongue, especially the spotted, and the 

 white masses around the teeth and gums, as well as the white coating 

 which often detaches itself irregularly on the fourth or fifth day 

 from the tongue of children taken ill with scarlatina, are easily 

 distinguished with the aid of the microscope and by the absence 

 of the fungus. I was unable to discover the thrush-fungus in 

 the latter, although I applied caustic potash. 



6. Remains of food and especially coagulated milk are easily 

 confounded without the microscope. Many of the cases men- 

 tioned by writers of thrush in the intestines and stomach, of 

 thrush-layers passing off with the excrement, were probably 

 nothing more than particles of such undigested coagulated milk. 

 The microscope alone can throw light on this subject. 



7. Ricord states that a certain syphilitic disease of the tongue, 

 accompanied by granulated papillae, resembles thrush very much. 



Therapeutics. Berg paid great attention to this point, and 

 recommends finally the nitrate of silver (from x grs. to 3J of water, 

 or more, according to Trousseau), which is to be painted over the 

 sore by means of a fine brush. He prefers the various sodium- 

 salts to the potassium-salts, and gives solutions of borax and nitrate 

 of soda in decoctions of sage. He recommends also cleanliness and 

 ointments against the erythema on the rectum and the genitals. 1
