MICROSCOPY. 243 
though it generally reduces animal temperature, the corpuscles 
become larger under its influence. Finally, acute anemia (pro- 
duced by arterial hemorrhage) increases the dimensions of the 
corpuscles.— Quarterly Journal of Microscopical Science. 
Comparative Size or Rep Broop-corruscies.— Mr. George 
Gulliver states in the same Journal, that recent measurements 
confirm his conviction that the size of these corpuscles, in families 
of fishes and reptiles, bears little relation to the size of the 
Species; while in many families of birds and mammals, there is 
such relation, the largest corpuscles occurring in the largest spe- 
cies and the smallest corpuscles in the smallest species. 
Viratiry or Orcantc Germs at High Temprrature.— This 
standard question of the experimenters in spontaneous generation, 
is attracting increased attention from its relation to the more 
fashionable question of disinfection. It is discussed in several 
numbers of the ‘Chemical News.” Mr. G. E. Davis calls attention 
to the fact that the ovens, in which fabrics are baked for pur- 
poses of disinfection, are often irregularly heated and may vary 
fifty degrees from the thermometer’s indication. Hence, making 
allowance for this uncertainty, the highest temperature desired 
cannot be safely attempted, and the temperature attempted may 
not be gained. He believes that the heat employed has little ac- 
tion upon the disease germs, and rather tends to encourage their 
growth. He advises that a vessel of carbolic acid diluted with an 
equal volume of water be placed near the clothing, in order to 
gain the combined effect o? the heat and the phenol vapor. 
Mr. Richard Weaver states that 350° Fahr. is the highest 
temperature available for disinfecting clothing: and Mr. H. 5- 
Yardley queries whether germs might nót be destroyed at inter- 
mediate temperatures although they would live at certain lower 
sree higher degrees; thus, might not life be destroyed at 330°, 
Which would continue to exist at 200°, 300° and 400°? 
_‘OBszct Teacnixe” rx Mrcroscory.— It is customary at the 
regular fortnightly meetings of the East Kent Natural History 
Society at Canterbury, England, to make dissections of plants 
ag animals, and microscopical demonstrations of the same. 
ig following items are derived from the Proceedings of this 
Size or Broop-piscs.— Mr. George Gulliver predicted that
