ts the analysis can be proceeded
with according to the operator's analytical knowledge.

Few operators are aware of the usefulness of an ordinary deep sea
grapnel rope, as used for cable work, in recovering specimens of the
fauna of any locality. The grapnel rope should be left down for a few
months, so that the denizens of the deep may get used to it and make
it their place of residence and _attachment_. The stench caused by
their decomposition, unless the rope be kept in water, when hauled up
will be in a few days intolerable, even to an individual with a
sea-going stomach. I tried several chemical solutions for preserving
specimens thus recovered, but nothing answered so well as the water
itself drawn up from the same depth as the rope was recovered
from.--_Chem. News._

THE SCIENTIFIC AMERICAN

ARCHITECTS AND BUILDERS EDITION

$2.50 a Year. Single Copies, 25 cts.

This is a Special Edition of the SCIENTIFIC AMERICAN, issued
monthly--on the first day of the month. Each number contains about
forty large quarto pages, equal to about two hundred ordinary book
pages, forming, practically, a large and splendid MAGAZINE OF
ARCHITECTURE, richly adorned with _elegant plates in colors_ and with
fine engravings, illustrating the most interesting examples of modern
Architectural Construction and allied subjects.

A special feature is the presentation in each number of a variety of
the latest and best plans for private residences, city and country,
including those of very moderate cost as well as the more expensive.
Drawings in perspective and in color are given, together with full
Plans, Specifications, Costs, Bills of Estimate, and Sheets of
Details.

No other building paper contains so many plans, details, and
specifications regularly presented as the SCIENTIFIC AMERICAN.
Hundreds of dwellings have already been erected on the various plans
we have issued during the past year, and many others are in process of
construction.

Architects, Builders, and Owners will find this work valuable in
furnishing fresh and useful suggestions. All who contemplate building
or improving homes, or erecting structures of any kind, have before
them in this work an almost _endless series of the latest and best
examples_ from which to make selections, thus saving time and money.

Many other subjects, including Sewerage, Piping, Lighting, Warming,
Ventilating, Decorating, Laying out of Ground
