2. Big Jaw in Horses and Cattle, and Its Eemedy. — The 



Live Stock Journal speaks of this disease as follows: "This is more properly 

 called 'dilation of the jaw bones.' In horses it is sometimes called ' big head ;' 

 it is a bony tumor, in which the interior of the bone is absorbed, sometimes 

 leaving a mere shell of bone divided into cells containing purulent or thick 

 matter. This is supposed to be caused by a deficiency of phosphate of lime in 

 food, rendering the bones deficient in this m.ost important element, and the fol- 

 lowing prescription is often given with good result: 



" Phosphate Poioder. — Phosphate of lime, 6 ozs. ; powdered golden seal, 2 

 ozs. ; powdered sassafrass, 3 ozs. ; powdered ginger, 2 ozs. ; oatmeal, 4 lbs. ; mix. 

 This will be divided into 16 parts, one given in the food everj- night. 



"This will have a tendency to restore the missing elements in the bone. 

 And the general diet should be food rich in phosphates. You may get your 

 phosphate of lime by boiling beef bones in lye of wood ashes, and after it is 

 reduced fine, wash with water and give a small quantity daily in food. The 

 first thing to do surgically is to open it and let out any matter that it conlaina. 

 Having removed the matter, inject the cavity with weak pyroiigneoTis aci<l or 

 weak carbolic acid. This will cleanse it and render healing possible." 



Remarks. — I should prefer the pyroligneous acid to the carbolic, and 1 part 

 of the acid to 3 of soft water would be weak enough to use at first; and after- 

 wards 1 to 2, or even equal parts, to speed its healing. Both of these acids are 

 disinfectant, i. e. , remove bad smells, as well as cleanse and heal, when used of 

 proper strengths as above. 



3. Big Head in a Colt, and the Remedy— "L. P. J.," of Ben- 

 zonia, Benzie county, ^Michigan, ]\Iay 27, 1880, wrote to the Post and Tribune, 

 of Detroit, as to the condition of his colt, as follows: 



"What ails the colt? In December I discovered a small lump or Inmch 

 coming on the left side of the face of my colt half way between the eve and the 

 nostril. This grew larger until about the size of a man's fist. I then opened it 

 with a knife. I had been using Centaur liniment and iodine and it had softened 

 a little, but when opened it did not discharge and bled but little. I had also 

 used beef brine. Almost immediately another bunch began to grow below this 

 or back of it, and now the side of the face is badly swollen and the colt is fall- 

 ing away in flesh. He is 3 years old this spring." 



To this their veterinarian, H. W. Doney, of Jackson, who had this depart- 

 ment in charge, made the following answer: 



" Big head. The disease is located on a line between the ^ye and the nos- 

 tril. Its first appearance is a small lump on the side of the head, which con- 

 tinues to enlarge until the whole side of the face becomes swollen. It ison both 

 sides sometimes. If your colt is very valuable, it will pay you to try a cure; if 

 not, get what you can for it and do not bother with it. 



*"' Remedy. — Take while arsenic the size of a common field pea. or 6 or 8 

 grs, ; wrap it in fine paper as close as possible, make an incision in the skin over 

 the hard tumor, insert the arsenic, or the paper containing it, take one stitch, 

 tie the ends in a hard knot, bleed the horse, and tm-n him out. In a short time 

 the horse will swell, and this wili continue until the effects of the arsenic are 

 exhausted. In a short time the effects of the arsenic will be seen. A circular 

 piece of skin and the porous bone of the face will begin to slough off. In thp 

 course of time the diseased portion will drop out. leaving a healthv sore, uinct
