Dear Mr. Leeds.

I am glad to receive your Lectures in printed form, and trust

that they may be widely read throughout the community.

Having been in the habit for several years past, of consulting

with you professionally in regard to the arrangements to be made

for heating and ventilation in plans for public and private

buildings, I take this opportunity to acknowledge the value

of the aid thus given; and as I feel assured, from a lengthened

personal experience, that your thorough knowledge of the subject,

both theoretically and practically, is calculated to render your

assistance particularly valuable in the adjustment of complex

and intricate plans, I trust that one result of the circulation

of your interesting pamphlet may be to introduce you more widely

to members of the architectural profession.

I remain, Dear Mr. Leeds,

Yours faithfully,
