Di'. 11. A. ('nttinii' read a pajx'!- on (he Pollen hron^'ht 

 down from the atmosphere in showers. Fii'st : he showed 

 that nmcji of the ha/iness of the atmosphere is from the 

 urains of pollen tloatinii" in it : second: though nearly all 

 of oni' |)lants l)l()ssoin in tin- spiini:-. pollen is found lloat- 

 inii in the atmosphere (hiriuii" the entire sunnuei" ; third : 

 that a iireat excess of the iii'ains found at all seasons are 

 from the Conifers, mostly Pines; ijuest. : A\'her(^ does it 

 come from so late in the season? Is it retained fresh in 

 the atmosphere dnrinii' the summei', or does it come from 

 more northern reiiionsy ('ertainly some pollen iirains

Prof. L. 1). Hall read a })aper on Trichina', giving' their 

 hahits from ohsei-vatioii and the residt of sovend experi- 

 ments, sliowinii' that after they were encysted in the nui.s- 

 cles tliey could not i»e propagated. He had fed to rats 

 llesh containing:' nndtitudes of encysted trichiuio without 

 propaiiJiting them, and as the rat was prohably as easily 

 infected as any animal ; it went far to show tliat they 

 t'ould not he thus propajrated, conse(]uently the cyst was 

 a tonih from which the trichina' could not liberate them- 

 selves. From this he would infer that after a time these 

 cysts would be al)sorbed by the natural })rocess of ab- 

 sorption and all trace of the former infection woidd then 

 l)e lost. This paper was illustrated by microscopic spec- 

 imens.
