EXPLANATION OF THE PLATE OF DISEASED BONES. 



1,2. Dilatation of the shank bone — beneath the knee of a cow. The 

 bone is sawn through its centre for the purpose of showing the interior ; 

 which, the reader will perceive, is very much dilated, especially about the 

 centre of the bone. Before the death of the animal this cavity was oc- 

 cupied by matter resembling pus. 



2. Shows the exterior of 1. 



3. This is a case of caries, or ulceration of the jaw bone. 



4. This constitutes dilatation of the jaw bone, a disease similar to that 

 shown in 1. 



5. This is a specimen of malignant disease of the jaw bone known as 

 cancer. Cancer has no respect for tissues, but involves all contiguous 

 parts in ruin. 



6. This is non-malignant tumor, and is occasioned by a disease known 

 as ostitis A small orifice will be perceived at the upper part of the tumor 

 through which the extensor tendons passed, and thus their free action 

 was secured ; therefore, as the disease respected the tissues in the imme- 

 diate vicinity, I call it non-malignant. 



DESCRIPTION OF "LADY WASHINGTON." 



The mammoth cow, " Lady Washington," whose portrait i§ truthfully 

 delineated in the cut, is the property of Winthrop W. Chenery, Esq., of 

 Belmont, Mass. She was dropped Feb. 22, 1854, and is, therefore, now 

 but five years old. Her weight is three thousand two hundred and sixty 

 pounds ! This extraordinary growth has not been attained by high feed- 

 ing, as, from a calf to the age of two years, she was herded with, and 

 fared the same as, ordinary calves and yearlings. The third and fourth 

 summers, when the feed became short in the pasturej she had a little meal. 

 She is of the Durham breed, from a stock known in the vicinity of Lake 

 Cham plain as the "Keyes Importation." She was raised in Pittsford, 

 Vt. Her dam was a first rate milker, and of extraordinary size ; her 

 weight, when not quite five years old, having been two thousand pounds. 



"Lady Washington" has dropped three calves — the two last having 

 weighed, at birth, respectively, one hundred and thirty-nine, and one 

 hundred and thirty-two pounds. Her last calf, when five months and 

 six days old, weighed six hundred and twenty pounds, and before reach- 

 ing the age of twelve months his weight was twelve hundred pounds. 

 She is now in calf by the imported Dutch bull, " Dutchman," from which 

 cross her owner anticipates highly gratifying results.
