As to disinfectants:

If in the case of disinfectants manufactured or sold in this State the
manufacturers, sales agents or dealers fail to show on the labels the car-
bolic acid coefficient or relative germicidal strength of such disinfect-
ants as compared with pure carbolic acid; provided, however, that deo-
dorants and antiseptics having no germicidal strength must be plainly
labeled and sold as such and such preparations as have no such germi-
cidal strength, shall not be labeled "disinfectants."

1910, ch. 156, sec. 140 E (p. 151).

170. No dealer shall be prosecuted under the provisions of sections
166 to 177 when he can establish a guaranty, signed by the wholesaler,
jobber, manufacturer or other parties residing in this State from whom
any article or articles which may or can come within the provisions
of sections 166 to 177 has or have been purchased, to the effect that
same is not adulterated or misbranded within the meaning of sections
166 to 177, designating them. Any guaranty under the provisions of sec-
tions 166 to 177 to afford protection shall contain the name and address
of the party or parties making the sale of such article to such dealer,
and in such case said guarantor or guarantors shall be amenable to the
prosecutions, fines and other penalties which would attach in due course
to the dealer under the provisions of sections 166 to 177.

171. The standard under sections 166 to 177 for the quality, purity
and strength of drugs shall be the standard set by the United States
Pharmacopoeia or the national formulary. That any standards of qual-
ity, purity and strength for foods or for drugs not already standardized
by the United States Pharmacopoeia or national formulary the stand-
ards heretofore adopted by the United States department of agriculture
are hereby declared to be the standards of purity, quality and strength
for such foods and drugs in the State of Maryland, except in the case
of ice-cream, in which case the standards are declared to be as follows:

(a) Ice-cream is a frozen product made from cream and other milk
substances and sugar, with or without a natural flavoring and contain-
ing not less than 4 per cent, of milk fat, to which may be added fresh
eggs and not exceeding 1 per cent, of pure gelatin, gum-tragacanth or
vegetable gum, without statement of such fact, and such goods may be
called ice-cream, provided the required percentage of fat is maintained.
But such product when containing 4 per cent, and upward of milk fat
shall be labeled, showing the percentage of milk fat; if imitation flavor-
ing materials are used, the label must state the fact.

(b) Fruit ice-cream is a frozen product made from cream, sugar and
sound, clean, mature fruits, and containing not less than 4 per cent, of
milk fat, to which may be added the same substances as in case of ice-
cream" under the preceding sub-section (a) and subject to the same
provisions for labeling.
