 ■ . • Ozone.- — Dr. Cutting remarked upon the haziness 

 of. thie atmosphere and ozone. In all cases when he 

 had collected microscopic particles from the atmos- 

 phere during the past Spring and Summer he had 

 not failed to observe more or less White Pine pollen, 

 and in many instances minute atmospheric algae were 

 found attached to the pollen grains. During the 

 thunder shower last Sunday immense quantities of 

 Pine pollen were brought down with the rain. Ozone 

 was very constantly present in the atmosphere up to 

 th(; I 5th of August through all the hot weather and 

 smoky days, and from that time to the 9th of Sep- 

 tember no ozone was' detected. During this absence 

 the atmosphere was tolerably clear, and northerly 

 winds prevailed with cool nights ; dysentery, cholera 

 morbu.s, typhoid fever, and other diseases of a low 

 type were pre\alent. and very severe; many deaths 

 ocrtired ina short time. 



I fis method of testing the ozone was with paper or 

 ... cloth soaked in a solution of one grain of iodide of 

 potassium and twelve grains of starch in one ounce 

 of "watfer. He kept a register of the amount of ozone 

 daily, estimated by a scale from one to ten according 

 to the discoloration of the test paper. But he found 

 that the quantity of ozone in the atmosphere was not 

 correctly registered or represented by the discolora- 

 tion of the test. During high winds a greater quantity 

 of ozone would come in contact with the test, to ob- 

 viate this defect an aspirator was devised by means of 

 which a given amount of atmospheric air was brought 

 absolutely in contact with the test in a given time. 

 He took two tin cans holding five gallons each, hav-
