Dear Sirs: I enclose cheque for $5.00, for which please send me " Steam-Heating Problems" and "Plumbing and House-Drainage Problems." I will be obliged, also, for a copy of your No. 6, Volume XVII., January 7th, 1888, which is a capital number, just read and sent to a Western engineer, a friend, containing much in his line of work.

I have looked at the Index of Volume XVI. It is a marvellous list of knowledge made accessible to the profession at small cost to each subscriber.

I congratulate you upon producing for the Building trade one of the most copious and valuable instructors in safe and sanitary building science in all branches ever published.

Faithfully yours, M. C. Meigs.

The Principles Of , Ventilation And Heating And Their Practical Application

BY

JOHN S. BILLINGS, M.D., LL.D. (Edinb.),

Surgeon U.S. Army.

PROFUSELY ILLUSTRATED.

This interesting and valuable series of papers, originally published in The Sanitary Engineer, have been rearranged and re-written, with the addition of new matter.

The volume is published in response to the general demand that these important papers should be issued in a more convenient and permanent form, and also because almost all the reliable literature on this subject has been furnished by English Authors, and written with reference to the climate of England, which is more uniform and has a higher proportion of moisture. The need of a book based upon the conditions of the American climate is therefore apparent.

The following will indicate the character of the subject-matter:

Expense of Ventilation - Difference Between " Perfect " and Ordinary Ventilation - Relations of Carbonic Acid to the Subject - Methods of Testing Ventilation.

Heat, and some of the Laws which govern its Production and Communication - Movements of Heated Air - Movements of Air in Flues - Shapes and Sizes of Flues and Chimneys.

Amount of Air-Supply Required - Cubic Space.

Methods of Heating: Stoves, Furnaces, Fire-Places, Steam and Hot-Water.

Scheduling for Ventilation Plans - Position of Flues and Registers -

Means of Removing Dust - Moisture,, and Plans for Supplying It.

Patent Systems for Ventilation and Heating - The Ruttan System - Fireplaces - Stoves.

Chimney-Caps - Ventilators - Cowls-- Syphons - Forms of Inlets.

Ventilation of Halls of Audience - Fifth Avenue Presbyterian Church - The Houses of Parliament - The Hall of the House of Representatives.

Theatres - The Grand Opera-House at Vienna - The Opera-House at Frankfort-on-the-Main - The Metropolitan Opera-House, New York - The Madison Square Theatre, New York - The Criterion Theatre, London - The Academy of Music, Baltimore.

Schools.

Ventilation of Hospitals - St. Peters-burgh Hospital - Hospitals for Contagious Diseases - The Barnes Hospital - The New York Hospital - The Johns Hopkins Hospital.

Forced Ventilation - Aspiiating-Shafts - Gas-jets - Steam Heat for Aspiration - Prof. Trowbridge's Formulae - Application in the Library Building of Columbia College - Ven-tilating-Fans - Mixing-Valves.

The book is free from unnecessary technicalities, and is not burdened with scientific formulae.

It is invaluable to Architects, Physicians, Builders, Plumbers, and those who contemplate building or re-modeling their houses.
