This communication is onl}'^ intended to do some justice to 

 a stand wliicli did not deserve to be omitted in the general 

 " round-up." 



"Amateur's " praise of Mr. Bullocli's stands especially was 

 richly deserved. As a friend of Mr. Bullock, I have been 

 much pleased that the great merits of his stands received such 

 recognition.

Editor The Microscope : — 



It may be interesting to microscopists to know of a Diatom 

 deposit in Mississippi, which has not, as yet, to my knowledge, 

 been noticed. It is south of Jackson, and I presume in the 

 same Geological horizon as the beds near Montgomery, Ala., 

 mentioned in your columns some time ago. I have not visited 

 the locality myself, and my discovery of it was almost acci- 

 dental. I had a pupil who showed me some " polishing earth." 

 That was some years ago, before I owned a microscope. Last 

 Winter something brought Diatoms and polishing powder into 

 close juxtaposition in ray mind I believe it was an article in 

 The Microscope. I wrote to my former pupil to send roe a 

 sample, and when I examined it my guess was verified. The 

 material is very poor, in perfect forms, the valves being very 

 much broken. I have noted one species of Surirella and several 

 of Naincula. I have not compared it with Electro-silicon, but 

 it is certainly a success as a polishing powder.

Mr. Tutfen West, the microscopical draughtsman, died in 

 England, recently, at the age of sixty-eight. He was unrivaled 

 as a draughtsman and a manipulator, and his love for his sub- 

 ject supplied him with never-failing energy. It was not, how- 

 ever, solely for his artistic ability that his collaboration was 

 eagerly sought by authors, for it was well known that he was 

 both able and willing to give help in the most varied directions
