QQ THE INTERNAL PARASITES OF 



same forms as those found inhabiting the ox ; and there- 

 fore, taking them in the same order for description, I 

 need only to add such particulars as were purposely- 

 omitted in my account of the parasites of the ox. In 

 this connection it will be remembered that I spoke of the 

 ravages of the " common liver fluke/' describing the rot 

 disorder as much more disastrous to flocks of sheep than 

 to herds of cattle. 



It is a mistake to suppose, as some do, that the 

 larger beasts rarely succumb to the fluke disease. The 

 earlier outbreaks which took place in the Duchy of 

 Coburg in 1663 and the following years were remark- 

 ably fatal, not only to sheep, but also to cattle, deer, 

 and hares. The Dutch outbreak in 1674 affected 

 nearly all the cattle of Zeeland. The French epidemic 

 of 1829 destroyed cattle in great numbers; for, in the 

 district of Montmedy alone, Davaine tells us that 

 5000 horned cattle perished; a similar fate overtaking 

 more than one-half of all the sheep grazing in that dis- 

 trict. As to the English outbreaks, they have been quite 

 as severe as regards sheep, but it does not appear that 

 our cattle have suffered to the same extent. Be that as 

 it may, I feel it quite unnecessary to enlarge upon this 

 point ; and the more so, because all who are interested in 

 the matter can readily obtain Professor Simonds's valua- 

 ble memoir or the " Rot in Sheep/' and in this small 

 treatise they will find the history, progress, symptoma- 

 tology, and treatment of the disease discussed in a 

 masterly and thoroughly exhaustive manner. 



I am here chiefly concerned to open out to view certain 

 hygienic and other particulars which bear more or less 

 strongly upon the sale of meat; but as regards the 

 general food question, and apart from the parasitic phase
