this manner the harm caused by the disease will be considerably 
lessened and rendered at least bearable until the next parturition. 
The farmer will do well to watch the milk and the udder 
very carefully, so that upon the appearance of any defect in the 
milk, an examination for infectious matnmitis may be made as 
quickly as possible. This will enable him to be on his guard 
at the right time to prevent a further spread of the infection. 
Until the examination is made, he should isolate the cow, milk 
her after the others, and milk her sound quarters before the dis¬ 
eased one. The hands should be smeared with lard while milk¬ 
ing instead of the common practice of dampening the hands 
with milk. None of the abnormal secretion should be allowed 
to fall upon the bedding. 
The hands are afterward to be well washed with soap and 
rinsed in warm 3 per cent, carbolic acid solution to disinfect 
them. The cow’s teats should likewise be first washed with 
soapsuds followed by warm carbolic acid solution. 
It is now stated anew that infectious mammitis appears with¬ 
out specific symptoms. In spite of numerous observations, it is 
not yet possible to make a certain diagnosis from the appearance 
of the milk or the udder. Sometimes some grains or shreds are 
found in the apparently normal milk, sometimes the secretion 
is viscid as phlegm, sometimes contains yellow flakes oris slimy, 
purulent and oftentimes bloody and shows a sediment after 
standing. Sometimes the disease is recognized by the bad, 
salty taste, sometimes by the curdling during cooking, and 
often the particles in the milk strainer. 
The general condition of the animal is not noticeably dis¬ 
turbed except that the mess of milk is constantly lessened. The 
udder is at times somewhat swollen and hard; very often with¬ 
out a noticeable change. For this reason a professional exami¬ 
nation is essential and this necessitates the microscopic exami¬ 
nation of the sediment of the milk samples from the diseased 
quarters. 
If anywhere, it is here that the use of the microscope for 
the confirmation of a diagnosis is necessary.
