 and circulated privately among- its members. We could 

 save the Club expense and gratify our subscribers by

 or three times per year. 



John C. House, of Troy, N. Y., who died January 22, 

 1897, was a man of g-entle and refined nature, quiet habits 

 and ag-reeable manners, of good heart, good sense and 

 g-ood will, a g-entleman of the old sort, whose presence was 

 ever a pleasure and an aid to his friends. May we see 

 more of his like, again ! He was a business man of profes- 

 sional instincts, whose leisure time was larg^ely spent, 

 with evident pleasure, in microscopical and astronomical 

 study. He was for ten years secretary of the Troy Scien- 

 tific Association, his last public act being the attendance 

 at the last annual meeting of the Association, and taking- 

 roug-h minutes of the meeting which was to have commen- 

 ced his eleventh year of service, but which his sudden 

 death prevented his writing out He was a member of 

 the Club for eleven years, and most of the time in charge 

 of one of the home-circuits in Troy; and notwithstanding- 

 the feebleness of advanced age, he was was one of the most 

 careful, trustworthy and efficient members. In the note 

 book of the last box that reached him, the date of its receipt 

 was carefully entered in his handwriting, though he lived 

 not long enough to reach the three days' time at which he 

 should, and would, have forwarded it. 



MICROSCOPICAL APPARATUS. 



An Oblique Light Illuminator. — When using light for 

 illumination, oblique to the axis of the microscope, it is 

 found that about 150 deg-rees is the best ang-le to put it at. 

 Less than that does not bring out the fine marking-s on the 

 Pleurosigma angulata, for instance, and more than that, is 

 more than the objective can stand so that the color results.
