stitutions, causing violent pains in the abdomen, nausea and vom- 

 iting of severe character, and a number of other troublesome and 

 indirect effects. 



To prevent tapeworm in the dog, it is essential that care be 

 taken in his diet, that he be not allowed to feed on carrion or ex- 

 crementitious matters, and that the meal with which he is fed 

 is thoroughly cooked. We may say, as a general rule, that no 

 meat should be used which still retains a red color, still less such 

 that contains blood ; and no reddish, still less red, fluid should 

 escape. The use of raw meat, or of swine flesh in any form, 

 should be entirely condemned. I will here say too, not only in 

 behalf of the canine, but the human race, that the presence of a 

 tapeworm is not only a source of danger to the health of the indi- 

 vidual, but to every one else in the same house with him, and to 

 every domestic' animal attached thereto ; and a person afflicted 

 with these parasites is more to be shunned than one suffering from 

 small pox or the itch ; the ways by which the parasite may be con- 

 veyed being both numerous and insidious. It is hardly necessary 

 to say that a tapeworm that has been expelled should not be 

 thrown aside. It should first be rendered harmless, which is best 

 done by pouring boiling water over it. 



ENTERITIS. INFLAMMATION OF THE BOWELS. IN- 

 TESTINAL CATARRH. 



In order to understand the frequency of intestinal inflamma- 

 tions, it is necessary to recall some of the anatomical peculiarities 

 of the mucous membrane of the intestines. Those who are famil- 

 iar with anatomy will remember that the network of minute blood- 

 vessels in the villi of the small intestine is situated immediately 

 under the epithelium,* and for this reason the vessels are directly 

 exposed to the influence of irritating substances. Furthermore the 

 venous twigs in the mucous membrane of the large intestine are 

 exactly the same as in the corresponding membrane of the stomach 

 (they form a capillary network, each twig of which returns upon 

 itself in a loop at the extremity of the projection, communicating 

 freely with the adjacent vessels, forming a close plexus around the
