perature range was much higher, and the general disturbance 
very great, death occurring on the twentieth day. In our animal 
the more severe course might have been expected from the large 
number of ripe segments administered ; but, perhaps the passage 
of many of the eggs in the foeces may have had something to do 
with the the mildness of the attack. 
How does it happen that the T. Saginata is so prevalent, when 
its “ measle ” is apparently so scarce ? Several causes bring this 
about. In the first place, the beef “ measle ” is smaller than 
that of the pork, and is not so opaque ; in consequence, it is more 
readily overlooked ; we are sure that any meat-inspector, unless 
specially instructed, would ha ve passed the flesh of our experi¬ 
mental calf. The larvae did not at once catch the eye in the red 
flesh, as in the case of cysticercus celluloses , but required to be 
looked for, though five to six mm. in length. Secondly, it is not 
improbable that many of the animals from which the infected 
meat is obtained are not extensively diseased, but present only 
one or two examples, easily overlooked in dressing the carcase. 
Calves and oxen are much less likely than pigs to get an entire 
strobile of a tape worm, or even many segments. And, thirdly, 
a very much greater quantity of beef and veal is consumed in a 
fresh state than of pork, and the former meats are not, as a rule, 
so thoroughly cooked. It is quite common to see joints on the 
table, the central parts of which have not been raised to a tem¬ 
perature sufficient to kill the larvae. 
LARGE HEART-CLOT FOLLOWING PURGATION.

December 21st, 1880, a mare, about eight years old, was 
brought to me suffering with very severe colicky pains. 
History: She had been brought here about two years pre¬ 
vious, and worked in light harness. After being here about 
a year, she had a slight attack of laminitis, after which she was 
thought unfit for city work, and sold to go into the country, where 
she was poorly fed and cared for. She had been in the city for
