MKKOSCOPKAL NOTES. 



Murder. At a small town near Pittsburg-, Alex. Killen 

 was c-liargod with robbing- and murdering- a woman who 

 had owned a jewelry store. The culj)rit had broken a 

 window and scraped the jewelry into a yellow satchel. In 

 the haste some g-lass was included. 



After Killen's arrest, such a satchel was found on his 

 premises and some small pieces of glass found in it. At 

 the trial, the District Attorney laid them on a sheet of

 presence of the spores of various species of fung-i which 

 were seen to have beg-un their g-ermination, and culture 

 experiments with the excrements of various snails pro- 

 iluced a larg-e number of g-erminating- spores of fung-i. 

 The same was observed on examining- the stomachs of 

 toads, in which the spores of Russula and Lactarius were 

 specially abundant. 



Honey Bee Secretes Fromic Acid. A fact which is in-

 after filling- a cell with honey and covering- it with the lid,
