motion, may occasion diarrhoea, I must not omit to mention 

 worms, as having frequently that effect. 



MCCCCXCII. I must also mention here a state of the in- 

 testines, wherein their peristaltic motion is preternaturally in- 

 creased, and a diarrhoea produced ; and that is, when they are 

 affected with an erythematic inflammation. With respect to 

 the existence of such a state, and its occasioning diarrhoea, see 

 what is said above in CCCXCVIII. and following. Whether 

 it is to be considered as a particular and distinct case of diarr- 

 hcea, or is always the same with some of those produced by one 

 or other of the causes above mentioned, I have not been able to 

 determine. 



MCCCCXCIII. Lastly, by an accumulation of alimentary 

 or of other matter poured into the cavity of the intestines from 

 several of the sources above-mentioned, a diarrhoea may be 

 especially occasioned, when the absorption of the lacteals, or of 

 other absorbents, is prevented either by an obstruction of their 

 orifices, or by an obstruction of the mesenteric glands, through 

 which alone the absorbed fluids can be transmitted. 



In one instance of this kind, when the chyle prepared in the 

 stomach and duodenum is not absorbed in the course of the in- 

 testines, but passes off in considerable quantity by the anus, the 

 disease has been named Morbus cceliacus, or simply and more 

 properly Cceliaca ; which accordingly I have considered as a 

 species of diarrhoea. 



MCCCCXCIV. I have thus endeavoured to point out the 

 various species of disease that may come under the general 

 appellation of Diarrhoea; and from that enumeration it will 

 appear, that many, and indeed the greater part of the cases 

 of diarrhoea, are to be considered as sympathic affections, and 

 to be cured only by curing the primary disease upon which 

 they depend ; of which, however, I cannot properly treat here. 

 From our enumeration it will also appear, that many of the 

 cases of diarrhoea which may be considered as idiopathic, will 

 not require my saying much of them here. In many instances, 

 the disease is ascertained, and also the cause assigned, by the 

 condition of the matter evacuated; so that what is necessary 

 to correct or remove it will be sufficiently obvious to practi- 

 tioners of any knowledge. In short, I do not find that I can
