T 10 The Microscope. 



sympathetic action upon the e3'e over the tube, equal to the 

 blurring out of fine detail, especially in work demanding the use 

 of lenses of high resolving power. Keeping the other eye open 

 is one of the very important " little things " in microscopical 

 manipulations. 



While the microscope may never reveal the form of a mole- 

 cule, still the microscopist should educate himself to feel optically 

 its vibrations. Aye, more. The writer has a ^ adjustable, homo- 

 geneous immersion objective of 1.43 N. A*., with which, when 

 the " i)ersonal equation " is just right, he imagines he can almost 

 •optically feel the " inter-vibrations " of an atom ! It seems a 

 sentient thing, a part of his very inner self. Under present light 

 I would not exchange this lens for the latest apochromatic. 

 Four years ago, by light from my diaphragm lamp with no other 

 aid than bull's eye and mirror, it convinced me that the trans- 

 verse stria' on AmpJdplura pelldcida are formed l)y oval beads, 

 length -wise of the transverse stria? of the frustule. I have never 

 •entirely separated these beads, yet, I have so greatly narrowed 

 the connecting link that I can readily believe them separated. 

 I know no objectives superior to those of American make. 



In " spirito " I know no past except it be the infinity anterior 

 to " Ea archa," hence no inconsistency in my s^Deaking of my 

 ancient friend, Got-Thothi-Aunkh, as a present associate. He 

 appeared on the earth nearly 950 B. C. ; a priest (?), archi- 

 tect, and of royal Egyptian blood, as evidenced by the leathern 

 cross on his thorax, with four seals thereon of Osorkon III. 

 Enter the Museum of Tulane University of New Orleans, La., 

 take a few steps forward and to the right, and you will feel your- 

 self physically and psychically present with him. Small samples 

 of each vestment in which he has been clothed for nearly 3,000 

 years have been in my microscopical den for two months, under- 

 going treatment, and microscopical examination, with specimens 

 •of the fibre teazed out from the cloth. A difference of opinion 

 existing as to this fibre, rather stirred up my microscopical 

 mettle, and for two months I have been under the pressure of 

 work in making an exhaustive and final settlement, with proof, 

 as to the cloth in which Got-Thothi-Aunkh was embalmed. 

 After over a thousand examinations and two hundred mounts, 

 I find no fibre but that of linen. 



The young microscopist may think that eight to twelve hours
