NOTES AND QUERIES
HINTS TO CORRESPONDENTS.
No attention will be paid to communications unless accompanied with the full name and address of the writer.
Names and addresses of correspondents will not be given to inquirers.
We renew our request that correspondents, in referring to former answers or articles, will be kind enough to name the date of the paper and the page, or the number of the question.
Correspondents whose inquiries do not appear after a reasonable time should repeat them. If not then published, they may conclude that, for good reasons, the Editor declines them.
Persons desiring special information which is purely of a personal character, and not of general interest, should remit from $1 to $5, according to the subject, as we cannot be expected to spend time and labor to obtain such information without remuneration.
Any numbers of the Scientific American Supplement referred to in these columns may be had at this office. Price 10 cents each.
