DISEASES OF THE OX AND SHEEP. 535 



movements of his body, in consequence of his own exertions 

 through space, it is the complex molecules of his brain which, 

 in virtue of their rapid and strong vibratory oscillations, produce 

 large and actually visible motions of a more simple kind in other 

 human beings. 



Many persons in these days who know how to use the 

 resources of civilisation without any great means produce 

 results, when quietly sitting in their rooms, the magnitude of 

 which even they themselves are far from realising. However, 

 every action is coupled with a re- action, and it is a mournful 

 and sad truth that, as Goethe has expressed it, action kills 

 thought and thought activity. Leaders of men produce gigantic 

 results, both by spoken and by written words ; but they often- 

 times do it at great cost. It cannot be too vehemently 

 emphasised that all the organs of the healthy body may be 

 kept in a state of activity by means of appropriate and well- 

 regulated exercise. 



We have, however, been digressing from our subject, and must 

 therefore now conclude with the practical remark that it is 

 advisable that ewes, even after they have been drafted out in the 

 order in which they will lamb, should be made to move about 

 gently now and again, in order that they may not altogether 

 lapse into inactivity. We may add to this the far more 

 important observation that those men who are engaged in 

 mental pursuits should on no account ever allow themselves 

 to desist entirely from health-giving out-of-door exercise. The 

 warm weather is, as we write, coming on, and all of us who feel 

 ourselves getting into bad habits of this order should now and 

 again shake off the chains which bind us to the office or the 

 stool, and spend an hour or two in the country lanes and woods, 

 among the primroses and the violets and the refreshing buds 

 and breezes of this genial and sweet season of the year, and 

 watch the merry gambols of the lambs, now rapidly advancing 

 towards maturity, and the sober demeanour of their patient 

 mothers, as they slowly chew the cud, while we indulge in the 

 musings engendered of sweet fancy. 



Peritonitis. 

 Peritonitis is the name given to a most serious disorder, viz., 

 inflammation of the membrane which lines the cavity of the
