          on the subject of air the opinion of the ancients was
given - a notice of modern discoveries - [Pneumated?]
chemistry - diffusion of gasses - quantity of the 
atmosphere illustrated by a large section of the
Earth surrounded with a thin band to represent
the atmosphere - A number of experiments were given
to illustrate the action of air as a supporter of combustion
phosphorous  [added: burned] on a plate - [crossed out: and] covered with a shallow
half glass - agency of air in the process of germination
Small quantity of soil placed in tall glass vessel 
some wheat planted in this - a candle was extinguuished
when plunged into the same - also importance of air
in respiration - the carbonic acid given off by the
lungs shown by an apparatus of this form
[drawing of a flask containing liquid, corked at the top and bearing two opposing bent tubes, one extending below the liquid surface and one ending above] when
the [paper torn, words missing] tube was put in the mouth and the air drawn
through no effect, but when the long tube was blown
through water became milky - [?] of this
air shown by the method of [Gal[crossed out: l]elio?]. 12 strokes were
given to the piston of a syringe attached to a copper
vessel ballanced by weights in an oppost [opposite?] scale
pan - the increase of weight was shown by pieces
of pith placed in the pan instead of metal weights
next stated the absolute weight of the air in the
lecture room to be about 2 tons (suppose room
40 by 40 and 25 hight' weight of air [nearly?] 4000 lbs

I find  that I only attended two
of these lectures and what I have given
above is the substance of these two perhaps
