The President thon appointed the usual stand.
Ing committees.
On motion Of DR.. Walker, tho association
went into committee Of the whole on the sub
Jeet Of the place to hold the next annual meet
ing.
Montreal, Pittsburg, Columbus, Ohio, and
other places were named, but the further con-
sideration OF the subject was postponed for the
present.
The Association reassembled at . p. NJ, and
proceeded to the consideration OF the subject Of
steam and hot water heating apparatus.
DR.. Corwin detailed the difficulties expe-
risnced by him In procuring boilers for the new
steam heating apparatus Of the institution
under his care. He gave them description
OF the pecullarltles Of the boilers and heating
apparatus.
DR.. Tyler remarked, on this subject, that
when he was connected with the New Hamp-
shire institution, the question had. arisen how
large the air-chamber ought to be In proper
tion OF the amount Of pipe put into 1t; and
also in regard to the 1ues connecting with
the different stories. The hospital was In q
latitude colder than that OF any hospital then
heated BY steam. In putting up the nues he
found many curious facts developed, showing
how small thing would disturb and divert q
current OF air. He came TO the conclusion that
the smoother the nues were made the more
easily the current OF air would pass through
them, and that II they were curVlllnear instead
OF having any angles in them 1t would be better
still.
In the Mclean Asylum he had adopted the
principle Of requiring one foot OF radiatory
surface to sixty cubic feet OF air, and had
found the plan to work very successfully.
DR.. Bancroft said that when a common air.
chamber was used In his Institution, It was
found before steam would pass entirely through
the coil IL would become partially condensed.
He, therefore, adopted the plan OF separate
alr-chambers, which rendered all the steam
| available.
In connection with this subject, the question
OF ventilation was discussed. In response Ia
q question put by DR.. Langdon, DR.. Tyler re,
marked that, in his new building, he con
structed q shaft, going from the boller-room
OF heated air passing up through this shaft
with which the yentilating nues OF the diff
ferent rooms connected, had worked very sue.
| cessfully.
DR.. Langdon then desired to know the gen
| eral opinion OF members Of the Association In
respect to the amount Of atmosphere required
for healthy person.
DR.. Gray replied, that In his institution the
supply furnished to the patients aud household
was about los, 900 cubic feet Of air minute
night and day, distributed well over the insti.
tuition, aud that was not toe much, In his judg.
ment, for seven hundred people. The fact Of
how much a man would breathe In a given
space Of time would depend upon his size
general health, the labor in which he was en-.
gagged, and the atmosphere by which he was
surrounded.
DR.. Laugdon stated that six hundred cubic
feet OF air per minute was required for a single
patient; another gentleman had Fixed It at three
hundred feet.
DR.. Gray suggested eighty cubic feet as the
proper amount Of air to be introduced per min.
ute for the use Of one person.
On motion OF DR.. CorWin, Q resolution was
adopted that committee of three bo appointed
TO draw up series Of propositions ON the sub
ject OF heating and ventilatlng institutions fol-
tho benefit OF the insane. DI. Corwin, But.
tolph, and Gray, were appointed on said com
mittee.
By request, DR.. Nichols then went into ar
able exposition upon the comparative merits ol
hot water apparatus and steam apparatus fol
heating purposes. Tho process OF heating
water by exhaust steam was so destructiy,
that he would not recommend 1t. The great
progress had been made in the matter of heat
Ing buildings by hot water, and so successful
had the experiment been that the practlcabilitN
OF heating buildings Of any slEe whatever b!
this method had been fully demonstrated.
A great deal Of Interesting discussion tool
place on this subject, but the crowded state
Of our news columns prevents us from gvInl
1t In detail.
, The meeting then adjourned.
