He trusted it was from one of the eggs hatclied eitlier by himself or hy the Thames 

 Angling Preservation Society, He collected the fishermen at Gravesend, and they 

 said that for more than thirty-three years a salmon had not been caught there before. 

 He was certain tliat if the cultivation of salmon in the Thames were attended to, 

 in a few years this valuable fish would be restored to the river. 



Mr. Buckland then gave some details respecting the Exhibition of Fish-culture 

 at Boulogne. He Avas happy to say that this congress did great good, commercially 

 and intellectually, inasmuch as representati-ses of all nations^from Norway and 

 Sweden in the north, to Spain in the south — met to interchange ideas, as well as 

 to establish business correspondence. He had received one silver and two bronze 

 medals from this Exhibition, a« well as a silver medal from the Exhibition at Arca- 

 clon for his labours in fish-culture.

On the Entozoa of the Dog in relation to Public Health, 

 By Dr. T. S. Cobbold, F.B.S. 

 In this extended communication the author gave an account of twenty-one dif- 

 ferent species of canine Bnfozoa. Amongst the most important forms were the 

 Tania echinococcus and the Trichina spiralis. In regard to the latter he remarked 

 that " it was probably not indigenous in the dog ; but the ease with which the 

 parasite was transmissible obliged us to class it as a canine parasite." He had 

 frequently reared it in the dog. Except in an indirect manner the dog would not 

 be likely to give the Trichna disease to man ; nevertheless, if infested dog's flesh 

 were eaten by us we should undoubtedly take the disease. At all events, there 

 was danger in allowing trichinized dogs to roam at large, since the consumption of 

 their flesh after death (by other animals) tended to propagate the disorder. Kats 

 especially would thus become liable to the disease. 



On the Teachinq of Science at the Public Schools. 

 By the Eev.' ^\ W. Eaeeab, 31. A., F.B.S. 

 After alluding to the strangeness of the fact that science, to which the most 

 characteristic progress of this epoch was due, should have been hitherto disregarded 

 at our oldest seats of learning, the author proceeds to argue that the introduction of 

 scientific instruction into the public-school system was necessary on three grounds : 

 first, because it called into play a different order of fixculties in boys who had studied 

 Language with success ; secondly, because it evolved those faculties in boys who 

 were naturally unsuited for classical training; and thirdly, because the schools had 

 ceased to be solely preparatory for the Universities, and were therefore bound to 

 give boys the opportunity of acquiring some knowledge which would be of direct 

 practical use to them in their future professions. He next treated of the difficulties 

 in the way of carrying out these views. Those difliculties did not in the least arise 

 from the prejudice of public-school masters, the majority of whom had used their 

 best efibrts to introduce more or less of scientific teaching into the schools, but 

 from the conflicting opinions of scientific men, from the absence of any definite 

 and well-considered scheme, from the badness of many existing text-books, and 

 from the immense amount of time already devoted to the teaching of the modern 

 languages, mathematics, and classics, a teiTu which now involved a very -nnde range 

 of studies._ The author suggested that many of these difliculties might be removed 

 if a committee were appointed by the Association, partly composed of scientific men
