only the Hw/natococcus which appears after a shower of 

 water on the soil, on the brooks, by the wayside. Haema- 

 tccoccus, or rather when it is green Protococciis, is ex- 

 tremely common on the water of stagnant marslies. Some- 

 times it is red and then the //(iem«^)coc-e/^.y appears. When 

 this water dries up, or rather when the land is dryer, 

 these may develop into Lichens or the green on barks and 

 fences. For these are but the same, Algae when in water, 

 Lichens when on dry land. Protococvus of a green color 

 when at the ordinary temperature and Red Snow when 

 the temperature is freezing. To see the Red Snow un- 

 derstandingly it is necessary to magnify it four or live 

 hundred diameters. That is to say one hundred and 

 sixty thousand or two hundred and fifty thousand times, 

 and this can be done by using an objective of I or 1-5 

 inch and what is known as a B, or second eyepiece or oc- 

 cular. A wide angled lens is not necessary, but certain 

 minute markings can be made out with such a glass 

 which are invisible to an ordinary lens. 



There were seen in the specimen from Tidal Inh't I'e- 

 sides the red spheres, which constitute the Red Snow it- 

 self, an individual of a stylospore, or stalked spoi'c, of a 

 Coniomycetal Fungus, showing that it lived at that tem- 

 perature ; i. e, about 33° Farh., and there are also com- 

 mon green Confervoid Alg*, belonging to the gemsOscil- 

 latoriacejB, which are long, filaments with close trans- 

 verse striae. When living they continually roll about 

 and in this way move like animals. 



In 1858 Mr. George Gibbs, Geologist of the North West 

 Boundary Survey found at an altitucb^ of 6500 feet on the 

 Cascade Mountains the Red Snow. He disgusted the 

 man who first brought it to him by eating it and exam- 

 ined by means of a lens, showed it to consist of " tadpole 

 shaped bodies with rounded heads and alternated tails, 

 perhaps two lines in length." In conclusion he says that 

 he believes that is the first notice of the occurren(re of
