I0'2 THE MANAGEilENT AND DISEASES dF THE DOG. 



Dr. Biidd observes : "In our domestic animals, the faften- 

 ing influence of fatty substances taken as food 'is far more 

 constant. It was well exhibited in the experirtients lately 

 performed by Majendie, for the purpose of ascertaining the 

 nutritivepoWefs of different kinds of food. In One o'f these ex- 

 periments, a dbg was kept entirely on fresh "butter, which it 

 Coritiriueid to 'eat, though iiot 'regtilarly, -fdr sixty-eight days. 

 It then died of inanition, although remarkably fait. All 'the 

 while the experithent lasted, the anirnal smelt strongly of 

 butyric aCid ; its hair was gi-easy, and its skin covered With a 

 layer of fat. On dissection, all the organs arid tissues weire 

 found infiltrated with fat. The liver, to use the common 

 phrase, was fatty ; and, on analysis, it was found to contain 

 a very large quantity of stearirie, but Jitfle or no oleine. // 

 had acted as a kind tif filter for the butter." 



Matiiy 'other expeHments'df the same kind were made with 

 hog's-lard and similar fatty substances, and with a like restflt. 

 The dogs became loaded with fat, but their muscles wasted, 

 and at length they died of inanition. In many of them, thfe 

 corriea sloughted. In all, the liver was fatty. These experi- 

 ments are dritei'estrng, as showing clearly that an artiihal rtiay 

 be loaded with fat, and yet die of inanition. 



They place in a strong light the truth of the observation 

 long ago made by practical physicians, that fat people are not 

 so str-ong as they IciOk, and, in general, ill bear loss of blood 

 or other depletive measures. The muscles of fat people are 

 small, and it is muscle which gives strength. These remarks 

 will equally apply to the lower animals, the horse in par- 

 ticular.
