INADMISSIBLE ARTICLES
The sample post must not be used for the trans- mission of goods for sale or consigned in execution of an order, however small the quantity. Postage stamps or forms of prepayment, whether obliterated or not, or any paper representing a monetary value, are also prohibited from transmission by sample post.
Articles for medical examination or analysis:
Deleterious liquids or substances, though otherwise prohibited from transmission by post, may be sent for medical examination or analysis to a recognised medi- cal laboratory or institute, whether or not belonging to a public health authority, or to a qualified medical practitioner or veterinary surgeon by letter post, but on no account by parcel post, under the following conditions:
1. Any such liquid or substance must be enclosed in a receptacle, hermetically sealed or other- wise securely closed, and this receptacle must itself be placed in a strong wooden, leather, or metal case in such a way that it cannot shift about, and with a sufficient quantity of some absorbent material (such as sawdust or cotton- wool) so packed about the receptacle as abso- lutely to prevent any possible leakage from the package in the event of damage to the receptacle. The packet so made up must be conspicuously marked FRAGILE WITH CARE, and bear the words PATHOLOGICAL SPECIMEN.
2.
Any packet of the kind found in the parcel post, or found in the letter post not packed and marked as directed, will be at once stopped and destroyed with all its wrappings and enclosures. Further, any person who sends by post a deleterious liquid or
or substance for medical examination or analysis otherwise than as provided by these regulations is liable to prosecution.
