Listed external meanings deny the possibility that these elements only are a「dish of water in sunshine.」Furthermore, elements also are「flow of fluids fed to captive or prisoner as torture」or「fluid flow, speak about netting on tray」formerly as EPIDEMIC, perhaps describing the flow of people talking about the spread of disease, evidenced by the poultices and nettings in trays removed from infected IDIOTS. Contagious diseases flowing from person to person also were spread by engaging in some sort of「flow, fluid」with an infected body part, as they still are today.
　「Fluid flow with tonguing mouth on dish」can only occur if the temperature of the fluids in the dish is sufficiently low to not cause injury by scalding of the lips, tongue, and hard palate of the mouth, and warm enough to not be in a frozen state that causes ice to adhere immediately to one's lips and tongue as a health-related event. Of course, only an IDIOT would attempt to drink fluids or eat otherwise. Yet, these elements may not explain the meaning EPIDEMIC unless that term is simply being applied to every bonobo-human eating the meal:
　「Occurring suddenly in numbers clearly in excess of normal expectancy, said especially of infectious diseases but applied also to any…injury or other health related event occurring in such outbreaks.」

　「Fluids and tonguing netting on tray, force-fed in a daily regimen of torturing a captive enemy」as WARM, TEPID, BODY-TEMPERATURE fluids gathered in nettings and caused by a recent EPIDEMIC that only an IDIOT would willingly eat. Refers to a TEMPERATURE approximately that of the human body because the poultice(s) from infected guards had just then been removed and placed before the enemy, to eat the contents resembling a soft-boiled egg. One must believe that the prisoner would LOOK OVER, VIEW AGAIN AND AGAIN the schmutz placed before his nose and mouth. Replacement elements were「flow from person in quarantine, forced isolation, in netting and poultice on tray」(溫) which have little to do with summer sunshine.
