626 MEDICINES. 



Vaseline. 



For making up ointments, vaseline has the advantage of not 

 being affected by the air. But for this purpose it is not as good 

 as lard, for its melting point is lower, and it is apt to spread 

 and leave the agent, of which it is the vehicle, to dry upon the 

 surface of the skin. By itself, it is useful in skin dieases. 



Zinc.

Zinc, Chloride of (see p. 68), 



Zinc, Oxide of, 



is used in powder, as an astringent, for sores ; or in the form 

 of ointment (1 to 8 of benzoated lard) as an application for 

 cracked heels, etc. 



Addenda. 



OHLO'RAL HYDRATE (p. 604) when given by itself in sufficiently 

 large quantities to produce insensibility, is dangerous. To obviate 

 risk in this case, Cadeac and Malet advise a subcutaneous injection 

 (p. 633) of 15 grains of morphine hydrochloride, followed ten 

 minutes later by an enema of about 3 oz. of chloral hydrate in 

 water mixed with a little gum. 



IODISED PHENOL is an admirable antiseptic and caustic. It 

 is made by rubbing 1 oz. of iodine and 4 oz. of pure carbolic acid, 

 at a gentle heat, until dissolved.
