3V1 TRAINING OF ANIMALS, &C. 



Nature affigns us vigour, fpirit, enterprife, and forefighl in 

 the early part of life, to treafure up the needful indulgences 

 for age. Parents are careful of our firft infancy ; we ourfelves 

 ought to provide for our latter childhood. 

 Confiderations The moft intelligent profefiional men have an opinion con- 

 refpeaing the cerning the fundions of the (kin, confonant with that of the 

 fltin •— vulgar ; and more refined, only from their afligning a general 



caufe for thofe efFe6ls, of which all of us are confcious. The 

 fkin is not regarded merely as an organ of fecretion, deftined. 

 for draining ofF fuperfluous moifture, or faline particles, from 

 the general mafs of fluids, but as a furface of more adive cir- 

 culation, which folicits the blood to the very extremities of the 

 veffels, and thus contributes to fupport and complete the cir- 

 culation of the blood, and to nourifli the parts within. The 

 fkin is regarded as connected, in a peculiar manner, with all 

 the parts of the cellular fubftance, interpofed betwixt the 

 mufcles, and involving the blood veflels. The ftate of the fkin 

 indicates the condition of that cellular fubftance, whofe office 

 it is to conduct the blood-velTels to all parts, efpecially to the 

 mufcular flefli, and to nourifh the parts; and while the circu- 

 lation of the fkin is lively and adive, that of the involved 

 parts can never flag. The condition of the bowels, and of 

 the {kin, are the firfl: and moft natural points for the phyiician 

 to attend to. It is by regulating thefe, that he regulates the 

 pulfe; by simulating or foothing them, that he ralfes or de- 

 prefTes the vital adions; and it is matter of common obferva- 

 tion, that in animals, a good fkin is the criterion of health, and 

 the drynefs of the fliin, the forming of fcabs or eruptions upon 

 it, and the clapping of the hair, (as it is called by thofe who 

 have the care of flock), are the firfl and furefl figns of ap* 

 proaching difeafe. 



Next to the free circulation of the blood through all the 

 body, terminating in the furface, that of the free tranfit of 

 the blood through the lungs, is effential to health. 



The oxydation or chemical change produced by air upon 

 the blood, is etfentlal to its vital properties, A free and pow- 

 erful refpiration is mofl effential to a frefli colour of the face, 

 to lively fpirits, and cheerful feelings, and to the healthy and 

 vigorous actions of the body. " It is my breathing hour of 

 the day," fay's Hamlet to Ofric. It is a princely thing to let 

 apart hours for exercifesj and there is little doubt, that if all
