Elastic Tubes, for giving immediate relief to Choked or 

 Blown Cattle, Invented by Dr. Monroe, Professor 

 of Anatomy in Edinburgh. 



These Tubes have long been found of the greatest 

 utility in preserving the lives of animals, when choked 

 or blown from eating too freely of clover, turnips, &c. 

 and only require to be more known to be in general use. 

 The wood mouth-piece being placed in the mouth of the 

 animal, and buckled round the head, assists the operation 

 and protects the tube ; the cup end of which will imme- 

 diately remove any obstruction in the throat, and the 

 other end will cause the immediate escape of the con- 

 fined air.
