into a higher form of parasite in the human body, although 

 there was a form found in these fish which was transformed 

 into the well known bothriocephalus latus which was well 

 known in Russia and sometimes in Ireland. 



Mr. MARBER wished to draw Professor Huxley's atten- 

 tion to a case which had come under his notice this year 

 in connection with a small river in Scotland. This year 

 there were a number of fresh- run salmon in the river in the

 disease never having been known to his knowledge in the 

 river before. He should like to ask if any reason could be 

 given why these fresh-run salmon, which never before ap- 

 peared in the river so early, had come there and brought

Professor HUXLEY said the salmon were quite innocent 

 of bringing the disease there; there was no doubt they 

 caught it in the river. 



Mr. MARBER said the river was prolific in salmon, but 

 they were always very light. They were never known to 

 arrive so early before, and these were not native salmon 

 of the river. 



Professor HONEYMAN (Canadian Commissioner) said 

 the subject of parasites had been brought to his attention 

 for some time past, and not long ago, when preparing the 

 collections on the other side of the Atlantic for the Exhibi- 

 tion, he one day bought from a countrywoman a very fine 

 trout, which he thought would be suitable to exhibit, and 

 took it with him to the Museum. A friend who took great 

 interest in subjects of the kind one of the foremost investi- 

 gators in fish anatomy informed him that he had just 

 discovered that some fish he had bought were full of para-
