PART B -- REFERENCES TO THE CHEMICAL EXAMINER
1. Medical Officer to be consulted about articles to be sent to Chemical Examiner.-- (i) The question as to whether any, and, if so, what articles should be sent for chemical analysis, and the transmission of such articles to the Chemical Examiner will rest ordinarily with the Medical Officer *[concerned] who should, however, attend to any requisition made by the Magistrate or the Police in this matter.
(ii) In certain cases Police may send articles direct.-- In cases where human subjects are not concerned the Police may send articles to, and correspond direct with, the Chemical Examiner.
(iii) All Magistrates are at liberty to forward any articles connected with any Criminal Case before them to the Chemical Examiner, but the desirability of their consulting the Civil Surgeon or other Medical Officer before doing so is obvious.
Every thing upon which the Chemical Examiner's opinion is necessary, should be forwarded to him with the least possible delay.

6. Precautions in packing bottles.-- (i) The several bottles containing the articles sent should be enclosed in a tin or wooden box, which should be large enough to allow of a layer of raw cotton, at least three-fourths of an inch thick, being put between the bottle and the box; the box should be securely fastened and covered with wax-cloth.
(ii) In cases where any of the contents of the bottles might prove offensive, the box must be of tin, and Macdougall's powder or charcoal should be dusted between the box and wax-cloth.
7. Articles to be packed and sealed in the presence of the forwarding officer.-- All articles on being put up by the forwarding officer, and sealed and numbered by him, should be packed in his presence and under his immediate supervision, and the package should then be sealed by him, in accordance with the usual rules of the Post Office as to parcels, in such a manner that it cannot be opened without destroying the seal. The seal used should be a private seal, and the same throughout.
8. Invoice of articles and post-mortem report or statement to accompany articles.-- In all cases of transmission of articles to the Chemical Examiner, whether by a Magistrate, Medical Officer, or the Police, a letter of invoice, giving a full description of the articles sent, should be despatched by post, together with the statement or postmortem report. A duplicate of the invoice should also be placed between the wax-cloth and the box to accompany the package. Both copies of the invoice should be stamped with an impression of the seal referred to *[above.]
The Chemical Examiner should be requested to return, if possible, any articles sent to him for examination which is likely to be required at the trial.

11. Proper custody of articles to be proved.-- In all cases in which articles are brought up in evidence, the custody of such articles, throughout the various stages of the inquiry must be clearly traced and established. Evidence must be recorded on this point, and the evidence should never leave it doubtful as to what person or persons have had charge of the articles at any stage of the proceedings. All such articles must be distinctively marked, and any reference to them in the record must be so clear as to leave no room for doubt as to the special articles referred to.
12.
