I46 SYNOPSIS 01? VETERINARY 



If used stronger than J-2 to 1 per cent solution it should not 

 be covered, as when prevented from evaporating a 1 per cent fre- 

 quently and a 2 per cent surely causes dry gangrene of the skin. 



The skin takes on a mottled, leathery character that stays in 

 situ for months unless forcibly removed. 



I occasionally make use of this mummifying effect of the 

 drug in treating well defined "quittors ;" injecting a 5 to 10 per 

 cent solution into the sinuses twice daily, (being careful not to 

 get it on the healthy skin), until the parts are thoroughly "mum- 

 mified" then taking a scalpel or narrow blade hoof knife and re- 

 moving the dead tissue down to normal tissue, after which the 

 part is treated as a simple wound. 



As an antiseptic for surgical purposes and for septic wounds 

 it is extremely valuable and cheap, but in injecting it into deep 

 wounds its effects must be watched lest it becoming too drying. 



One drachm of the medicinal product to one pint of water 

 makes a good average strength for general purposes. 



Puerperal Fever and other forms of septic infection in the 

 human being are being successfully treated by the administration 

 of one minim of Formaldehyde in an ounce of water every l / 2 

 to 1 hour until improvement is shown, then less often. 



This would suggest its use in about 12 or 15 minim doses 

 for horses and 15 to 30 minims for cattle. 



It is also used intravenously for the same conditions in the 

 human being, not over 750 c.c. (about 233/2 ounces) of a 1 to 

 5000 solution is used at one time, preferably in a normal salt so- 

 lution, (see sodium chloride) that is to 5000 parts of normal 

 salt solution, add one part of Formaldehyde. 



It should not be long continued for internal use as it causes 

 atrophy of the gastric and intestinal glands with a condition of 

 general inanition.
