"The cseca were thin and contained very moderate amount of faeces. I 

 should say they were partially empty. No sign of mucus or other accumula- 

 tion. The walls were very thin and there were numerous Trichostrongylus 

 pergracilis. The contents showed large numbers of eggs. The mucosa of 

 the cseca did not show any petechial spots or appear to be congested, but 

 this may have passed off. The mesenteric veins were not dilated. Lungs 

 showed i^ost-mortem staining." — R. T. L.

Full dose of forty-four days' old culture. 

 This bird is kept on same fouled ground all through to end 

 of experiment. 



Used a culture seventy days old, in wliich were mo-\dng 



sheathed worms. 

 Examined cKoal e.\creta. No Trichostrongylus ova and very 



few coccidia. 

 A full dose of August 6th's best culture. 

 Same culture used, twenty-two days old. 

 Used centrifuged culture of August 6th, now twenty-nine 



days. 

 Used very old culture with living slieathed worms. The 



bird is strong and well. 

 A very full dose of metamorphosed worms, made (B) August 



23rd. Cajcal excretion contains still only a few ova, one 



or two ova in one inch field. A very few coccidia. 

 Ctecal excreta — a uniform but spare infection, not more than 



one or two to the one-inch field. 

 Culture of September 14th. Caecal excretion show two or 



three ova in one-inch field certainly more than before. 

 Full dose of September 14th, culture. Living and meta- 

 morphosed worms in considerable quantity. Still strong 



and brisk and very lively. 



(This was the last visit I made to Frimley.) Examined 

 csecal excreta and found a good many Trichostrongylus 

 ova and a number of coccidia sporulating. 



The bird, now two years old, is small, but looks well, and in good feather. 

 Has mated with two hens this season, both now laying. 



This young cock has proved himself to be extraordinarily resistant to 

 infection, compared with the young hen (B), which died in less than 

 twelve weeks, after six doses of culture. This bird is still quite healthy, though 

 dosed nine times with similar cultures, and kept on the same ground all the 

 while for auto-infection.
