180 ENTOZOA. 



here say is, that most of them when fairly tested have been found 

 to fail ignominiously. Every year we hear of the adoption, often 

 with enthusiasm, of new so-called specifics, or of ancient medicines 

 whose employment had long fallen into disuse. Thus, for ex- 

 ample, in the April number of the " Journal des Veteriaaires du 

 Midi," for 1860, we find M. Raynaud strongly recommending soot, 

 in doses of from one to three spoonfuls, to be followed up by the 

 administration of a grain of lupin for tonic purposes. In like man- 

 ner, we have received from France wonderful accounts of the me- 

 dicinal virtues of a certain foetid oleaginous compound, the value of 

 which has been lately put to a fair test by our distinguished vete- 

 rinarian, Professor Simonds. This last-named gentleman having 

 with infinite care and trouble undertaken a series of experiments 

 with the nauseating remedy in question, informs us, ia the " Scot- 

 tish Farmer and Horticulturist," as a result of his inquiries, that 

 he fears " we must conclude that this supposed cure of rot in sheep 

 has proved quite ineffective for good in our experience." Finally, 

 in regard to the merits of Mr. Youatt's method of treating the 

 malady, as if it were an ordinary inflammation of the hver, reqiiir- 

 ing the adoption of bleeding and other sharp, antiphlogistic mea- 

 sures, one can only regard the plan as altogether a mistake. 

 However, those who desire further knowledge on this point should 

 consult the admirable essay by Mr. Simonds, to which I have so 

 frequently had occasion to allude. 



Summary. — Correlating all the known data afibrded by the ex- 

 perience of our best veterinary authorities, by observant naturalists 

 generally, by my own researches, and by the recent experimental 

 investigations of Continental helminthologists, I may here state in a 

 tentative manner the conclusions to which a due consideration of 

 all these facts inevitably lead. The deductions here recorded may 

 eventually require modification in respect of their minor details ; 

 but in the main they will be found substantially correct, and there- 

 fore be likely to convey that kind of information which can scarcely 

 fail to interest those more immediately concerned in the preserva-
