3/6 The Management and Diseases of the Dog. 



dreadfully injured. It being near the Thames, his owner 

 took him to the edge of the river, and dashed some water 

 over him, and he rallied a little. Professor Simonds detected 

 a fracture of the skull, with pressure on the brain, arising 

 from a portion of depressed bone. The dog was perfectly 

 unconscious, frequently moaning, quite incapable of stand- 

 ing, and continually turning round upon his belly, his straw, 

 or his bed. It was a case of coma ; he took no food, and 

 the pulsation at the heart was very indistinct. 



."I told the proprietor that there was no chance of re- 

 covery, except by an operation ; and even then, I thought 

 it exceedingly doubtful. I was desired to operate, and took 

 him home. ^ 



'■ The head was now almost twice as large as when the 

 accident occurred, proceeding from a quantity of coagulated 

 blood that had been effused under the skin covering the 

 skull. I gave him a dose of aperient medicine, and on the 

 following morning commenced my operation. 



" The hair was clipped from the head, and an incision car- 

 ried immediatelyfrom between the eyebrows to the back part 

 of the skull, in the direction of the sagittal suture. Another 

 incision was made from this to the root of the ear. This tri- 

 angular flap was then turned back, in order to remove the 

 coagulated blood, and make a thorough exposure of the skull, 

 I was provided with a trephine, thinking that only a portion 

 of the bone had been depressed on the brain, and it would be 

 necessary ,'with that instrument, to separate it from its attach- 

 ment, and then with an elevator remove it ; but I found that 

 the greater part ofthe parietal bone was depressed, and that 

 the fracture extended along the sagittal suture from the coro- ' 

 nal and lamboidal sutures. At three-fourths ofthe width of 

 the bone, the Iracture ran parallel with the sagittal suture 

 and this large portion was depressed upon the tunics ofthe 

 brain, the dura mater being considerably lacerated. 



" The depressed bone was raised with an elevator, and I 

 found, from its lacerated edges and the extent of the mis-
