by boiling or by live steam, or finally by chemical disinfectants. 

 A 2 per cent, solution of cresol will prove effective. Dampening 



the objects and placing in a box in louse condition and filling the 

 box with formaldehyde gas, generated by mixing permanganate 

 of potash with formalin in the proportion of 3 to -f will prove 

 effective. 



]\Iilk, butter, cheese and other uncooked products of the dairy 

 are best and most safely treated by boiling, or burying deeply 

 during the active stages of the disease. Milk may be disinfected 

 by mixing 1 pint of formalin in 8 gallons of liquid in a can. cover- 

 ing closely, mixing thoroughly by shaking, and letting it stand for 

 several hours. Or the milk may be boiled and will be perfectly 

 safe even for consumption. The danger of the infection passing 

 into butter and cheese may be obviated by raising the milk and 

 vessels to the boiling point before proceeding with the manu- 

 facture. 



The carcasses of animals slaughtered while suffering from 

 aphthous fever are in Germany and France usually put on the 

 market as food, the precaution having been taken to remove the 

 skin and hoofs, and to scald the. tongue (Edelmann, Ostertag). 

 Boas (Twentieth Century Medicine) questions the "propriety' 

 of this, as "obviously, in this way, the noxious material can be 

 but imperfectly destroyed." This objection becomes far more 

 sweeping when we view the matter from the side of the suppres- 

 sion of infection. Allowing that man is usually protected by the 

 cooking of the meat, and that even apart from this the meat, like 

 the milk, rarely does infect men, yet the carcass does in itself 

 contain the germs, and receives still more in dressing, at the hands 

 of the butcher, and pigs at least are likely to tact raw scraps from 

 the kitchen and thereby contract and disseminate the disease. We 

 cannot, therefore, look upon the marketing of the flesh as a safe 

 resort, ft is but one example more of the blameable imperfection 

 of the Continental method, the evil fruits of which are charged 

 on the supposed impossibility of controlling this disease by quar- 

 antine alone. The meat certainly ought to be carefully isolated 

 until superheated and canned. If safety demands the superheat- 

 ing of the carcasses before marketing, no less is such a measure 

 necessary in the case of blood, offal, tripe, sausage cases, fresh
