and clearly separates the two pole (coccoid) ends, and the mature 

 object is again presented to our view, Fig. 6.* 



We have thus described the normal, or general, cycle of develop- 

 ment of the micro-etiological organisms of the American, English and 

 German Swine Plagues, the American Southern -Cattle Plague, Hen 

 Cholera, the German Wild-Seuche (of deer, swine and cattle), and 

 Rabbit Septicemia, all of which diseases are caused by a member of 

 this class of " belted " germs and should be classed as extra-organis- 

 mal, local, or land septicsemiae . It seems to me that the germ of 

 Yellow Fever, as well as the disease itself, should also come into this 

 group. I am sorry to say, that, notwithstanding the result claimed 

 by Freire, that I am unable to find a single exact and detailed 

 description of the germ with which he works and which should, there- 

 fore, be the etiological moment in the Yellow Fever if there is any 

 trustworthiness in Freire's statements. 



PROCEEDINGS OF SOCIETIES. 



THE MICROSCOPICAL SECTION OF THE WELLINGTON 

 PHILOSOPHICAL SOCIETY. 



^"T^HE Wellington Philosophical Society is one of the local socie- 

 -*- ties affiliated to the New Zealand Institute. There are seven 

 of these societies located in the chief towns of New Zealand, and the 

 results of the work of each appear in the Annual Volume of Transac- 

 tions of the New Zealand Institute. 



In Wellington there is a Microscopical Section of the Society, 

 holding fortnightly meetings in the winter. Each member is at lib- 

 erty to pursue privately any branch of scientific work that suits him, 

 but the Section as a whole, with a view to the preparation of a com- 

 bined paper, prosecutes some special line of study. 



The members would be glad to exchange material with any one 

 who would do the same. The principal objects desired are Algae 

 (Desmidies and Diatoms), Zoological (Honcopterous Insects). 



The first meeting of the Section this season was held on the 26th 

 of March in the museum lecture room. After some discussion it was 

 resolved that the subject for work should be a continuation of that of 

 last season's, namely: the collection, examination and description of 

 the flagellate, ciliate and tentaculiferous Infusoria of New Zealand.
