the cell, so as to press upon all parts 

 evenly, or one side may be crushed 

 lower than the other, and spoil the 

 appearance of the cell. 



These wax cells possess certain 

 advantages over others, among 

 which 18 the slight cost of the 

 necessary apparatus for making 

 them. The punch is not a ne- 

 cessity, but .it saves a good deal 

 of trouble, and may be obtained 

 for twenty-five or fifty cents, and 

 one punch cutting a hole eleven- 

 sixteenths of an inch will cut 

 out a piece that will make two cells 

 fit for five-eighth and half-inch 

 covers. The circular pieces that 

 are turned out of the centre may 

 be used again for a smaller cell, or 

 for making cells for opaque objects 

 with the brass curtain-rings. The 

 cells being made and fastened upon 

 the slide at one operation are not 

 liable to that distortion which re- 

 moval from the punches is liable to 

 cause. They can also be made of 

 any size. 



These cells are very pretty in 

 appearance, but I have had no ex- 

 perience in their practical use ; 

 my friend, Mr. C. C. Merriman, of 

 Rochester, IST. Y., informs me that 

 he has used them much and 

 approves of them highly. He 

 states that the wax must be care- 

 fully covered with some cement, 

 whether used for fluid or dry 

 mounts ; for it is said that certain 

 volatile portions will ultimately 

 collect upon the glass cover of dry 

 mounts or mingle with the preser- 

 vative media in liquid mounts, and 

 thus spoil the work in either case. 

 His experience is, that the best ce- 

 ment to cover the wax with is Miil- 

 ler's liquid marine-glue. After 

 coating the ring with this, it is used 

 in the ordinary way.

"The scientist should allow his 

 name and influence to be used only 

 when the full bearing of his state- 

 ments, in spirit and in probable 

 effect, and without qualification or 

 reserve, is exactly what it purports 

 and seems to be. Nor should he 

 allow his aid to be used to the det- 

 riment, in his judgment, of honest 

 individual or social interests. I am 

 aware of the difliculty of his posi- 

 tion ; he cannot hope to judge cor- 

 rectly every case in advance, which 

 even the members of the legal pro- 

 fession do not claim ability to do, 

 but he should, in my opinion, limit 

 his influence to those cases where 

 the facts within his cognizance seem 

 to fully, not partially, uphold his 

 action, and where they do not seem 

 likely to be used in the accomplish- 

 ment of wrong. Fortunately, he 

 is under no compulsion of usage or 

 the necessities of society to act in 

 any case against his own convic- 

 tions. The custom of defending, 

 so far as practicable, almost every 

 cause, however undesirable its suc- 

 cess might be, although apparently 

 unavoidable is, in the judgment of 

 those outside of the profession best 

 qualified to decide, the least satis- 

 factory point in the relations of 

 present legal usages to the inter- 

 ests of society ; a point at which 

 no doubt all honorable members of 

 the profession take the greatest 

 care to prevent their personal suc- 

 cess and that of their clients from 

 becoming a hardship to others ; 

 where persons without character, 

 who are liable to creep into any 

 profession without becoming assimi- 

 lated to it, find it easiest, for selfish 

 purposes and with impunity, to 

 make themselves the enemies in- 

 stead of the friends and protectors
