THE HOG. 



one animal to another of a different species, and even to the human 

 being. 



In Austria, if mange appears in the hog within eight days after 

 the sale, it is presumed to have existed at the time of the said sale, 

 and the animal is returnable to the vendor ; and when it can be 

 proved that he was aware of the unsoundness, he not only has to 

 return the purchase-money, but also to indemnify the purchaser for 

 any loss or inconvenience he may have sustained, besides paying a 

 fine equal to one-tenth of the value of the animal. 



That the actual disease, namely, the scab and the irritation, arises 

 from the presence and proceedings of the acari, there can be no 

 shadow of doubt ; but the question is, whence do these acari arise 7 

 Are they the product of some morbid state of the skin, arising 

 from constitutional derangement, or created by miasma or effluvia ? 

 We find mange in animals that are fed on too stimulating food, we 

 also find it in others that are neglected and badly fed. How can 

 these contradictions be reconciled ] Here is a vast field for scientific 

 research and experiment. As every grain of earth, and every drop 

 of water, and every particle of air, is peopled with living beings, 

 developed by certain causes, it is by no means an improbable theory 

 to suppose that the germs of the acari may exist in a dormant state 

 in the skin, and only be called into actual life by some of the vitiating 

 influences which neglect or mismanagement produces, and once ex- 

 isting, they follow the law of every created being, and propagate and 

 multiply, and pass from one animal to another either by actual con- 

 tact, or by the intermediation of some other substance which both 

 had touched. We admit, however, that this is mere theory, and call 

 upon our professional brethren to aid us by their researches in our 

 endeavors to discover the actual truth. 



MEASLES. 



This is rather a sub-cutaneous than an actual disease of the skin, 

 consisting in a multitude of small watery pustules developed be- 

 tween the fat and the skin, and indeed scattered throughout the 

 cellular tissue and adipose matter. It has, by many, been regarded 

 as a milder form of leprosy ; and so far as our present limited know- 

 ledge will allow us to judge, this supposition appears by no means 

 an erroneous one. 



The external appearances attending it are the development of red- 

 dish patches, somewhat raised above the surface of the skin, on the 

 groin, the arm-pits, and the inside of the thighs at first, and subse- 

 quently on other parts of the body. The attendant symptoms are 

 acceleration of the pulse, heat of the skin, cough, discharge from the 

 nostrils, loss of appetite, nausea, swelling of the eyelids, feebleness
