The urodaeum serves only as a passage, the urine being mixed with the faeces in the chamber above.
(A and B from Lankester's Treatise on Zoology, part iv., C original.) of proglottides or of eggs which are disseminated along with the faeces of the final host and subsequently eaten by herbivorous or omnivorous mammals, insects, worms, molluscs or fish.
Discharges - vomited matters, sputa, urine and faeces - are possible media by which plague is spread from person to person.
It was also shown that animals may become infected through the faeces of a flea which has been fed on plague-infected rats.
The greater part of a dose of quinine sulphate administered by the mouth may be recovered, as a rule, from the faeces, this being much the most wasteful method of giving quinine.
Lower down in the bowel these compounds are converted into ferrous sulphide and tannate, and are eliminated with the faeces, turning them black.
Unchewed oats pass out in the faeces uninjured, so that they are capable of germination, and are of less than no value to a horse.
(I) In the former class the eggs are extruded with the faeces, and the young become fully formed within the egg, and when accidentally swallowed by their host are liberated by the solvent action of the gastric juice and complete their development.
The innermost, the coprodaeum, is an oval dilatation of the end of the rectum, and attains its greatest size in those birds whose faeces are very fluid; it serves entirely as the temporary receptacle of the faeces and the urine.
Haematemesis is vomiting of blood, the colour of which may be altered by digestion, as is also the case in melaena, or passage of blood with the faeces, in which the blood becomes dark and tarrylooking from the action of the intestinal fluids.
It colours the faeces black owing to the formation of sulphide.
With the faeces of the host the larva hatches out and swims freely for a time.
