mucous corpuscles were all active and the leucocytes 

 presented no sign of them. It should be said that the 

 blood serum presented on March 17, quite a number of 

 automobile saltatory copper-colored spores which I have 

 been taught by another observer to be syphilitic and 

 which I have for many years found to be as reliable a 

 sign as any other physical sign. I think the said intra 

 leucocyte spores were syphilitic. I am not so sure of 

 the intra mucous corpuscle spores, though the re-estab- 

 li^ment of their motions after the cessation of the intra 

 leucocytal movements is an exceedingly interesting 

 chemical fact. Long ago was I taught by another 

 observer that the swarming bodies in the oral mucous 

 corpuscles were cryptogamous spores introduced from the 

 outside in food and that a healthy baby nursing a healthy 

 mother's breast has no such enlarged oral mucous cor- 

 puscles nor swarming molecular contents. I corroborate 

 this. In the above case the abnormal morphology of the 

 urine became normal and not long ago the patient re- 

 turned to give thanks for his entire restoration to health.

Lake Erie Water. — G-atherings from this lake are 

 now especially full of Melosira, Stephanodiscus, Cera- 

 tium, Daphnella, Pediastrum, Oscillatoria and a host of 

 smaller things. Cyclops is conspicuously absent from 

 the gatherings. The latter appear in great abundance, 

 in the spring. The gatherings exhibit a different fauna 

 and florg, almost every month. Why is this so? 



Cephalo/.ia sullivantii — This is one of the Junger 

 maniaceaj, the scale or liver mosses. It is the smallest 

 of the species and one of the minutest plants visible to
