1861.] Ringworm. 823exhausting delineation of the disease, I will add a few eonelusions:1. Uraemia and ammomemia are different conditions, producing,in many respects, different symptoms.'2. Both appellations point merely to those constituentsof urine which mix with the blood, being* in the one caseurea, in the other carbonate of ammonia. There may bein the hlood, besides them, some other elements of urine.3. Ammonhemia has been mentioned and described, byformer physicians, under the names : uroplania, urodilyasisischuria, paralysis of the bladder, &c.4. This disease may result either in direct resorption ofdecomposed urine from the urinary organs, or in absorptionof urea changed to carbonate of ammonia, in the intestinalcanal.The excretion of the morbid matter thus accumulatingin the blood, is effected by exhalation through the lungs,the skin, and the mucous membrane of the stomach andintestines. Cincinnati Lancet $ Observer.On Ringworm. By Jonathan Hutchinson, of London.1. True Ringworm, or Tinea tonsurans may be defined as adisease affecting either the scalp or the general surface, inwhich circular patches are formed, on which the hairs breakshort, and a slight, branny desquammation is seen, bothhairs and epidermic scales exhibiting under the microscopethe sporules and thalli of a fungus.2. Ringworm in the scalp is rarely seen, excepting in children: but on the general surface is not very nnfrequeut inyoung adults.-contagious, and spreads by contagion only.4. It is not attended by any peculiar form of dyscrasia,but on the contrary, often attacks children in perfect health.much more easily cm able on the general surfacethan on the scalp, owing to the circumstances, that in thelatter situation the fungus has obtained access to the folic leaof the hair-.G. Being a purely local d ringworm does not require,ay constitutional treatment.
