lodol. 
Tetraiodopyrrol, a derivative of the base pyrrol (QH5X) obtained 
by the direct action of iodine upon the base in the presence of alcohol. 
Properties. — A light, grayish-brown, crystalline powder without 
odor or taste. Very slightly soluble in water (1:4900). much more so 
in alcohol (1:9): soluble in fixed oils. 
Dose. — ‘‘Average dose: 0.250 Gm. =250 milligrammes (4 grains)." 
(U. S. P.) 
This is one of the vast number of compounds proposed in the last 
few 3'ears as substitutes for iodoform. The iodine of iodol is appar- 
ently less easily split off the molecule than that of iodoform, and it is 
said to be less liable to produce poisoning. 
Other iodine compounds. — Among the enormous number of other 
iodine compounds proposed as substitutes for iodoform may be men- 
tioned: Thymolis lodidum (U. S. P., Eighth Decennial Revision, com- 
monly known as aris.toI)\ airol (bismuth oxy-iodo-gallate. with 20 per 
cent of iodine); >anoform (diiodo-methylsalicylate); the potassium, 
sodium, mercury, and zinc salts of sozoiodolic acid (phenol-sulphonic 
acid in which two atoms of hydrogen have been substituted by two 
atoms of iodine — C6H,l2< 
(OH) 
SO.OHy' 
, known as sozoiodokites : nosojdien, 
antinosine^ and eudaxine (all iodine compounds of phenolphthalein): 
Josophan and europhen (combinations of cresol and iodine): Joretin and 
vioform (derivatives of quinoline containing iodine): diiodofonn 
(tetraiodoethylene. GIJ: sodium diiodosalicylate; acetone iodide: 
iodoso-benzoic acid, etc. 
Various mixtures of iodoform and other substances have been made 
with the object of concealing the odor of the former; thus, eJca-iodo- 
fonn is said to consist of iodoform and paraformaldehyde; anozol of 
iodoform and thymol: iodoformin of iodoform and hexamethylene 
tetramine, etc. lodoformogen is a proteid compound of iodoform, 
lodoformum Aromaticum, X. F., is a mixture of iodoform and 
coumarin. 
KAOLIMM. 
Kaolin. 
Official in the British Pharmacopoeia under same name. A 
native aluminum silicate, consisting largely of the pure silicate 
HgAkSioOg—HoO. It is a very pure clay. 
Properties. — Soft, white or yellowish-white powder, odorless, and 
having an earthy or clay-like taste. 
Insoluble in water.
