176 THE AMERICAN MONTHLY [September, 
posed on the world with inferior products ; neither has a commission of any exhibition 
ever rendered such a verdict. Contrary to that, in World, International, and State Ex- 
hibitions I was always recognized as master of the masters, which is shown by the fol- 
lowing first-class awards :— 
Prize Medal of Honor and Diploma of Merit awarded at the Centennial Exposition 
of 1876. Also, First Prize Medal and Diploma, International Industrial Exhibition, 
Buffalo, N. Y. 
Three First Prize Medals, Utica Mechanics’ Association. First Premium Medal, 
Syracuse Mechanics’ Association. Silver Medal and Certificate of Highest Merit of 
New York State. 
Regarding the sentence that I do not publish my method of ruling, I do not want 
to dictate to other persons what methods to use to accomplish a certain work—in 
somewhat by showing and illustrating my machine—neither do I want to contradict 
those who attempt to illustrate how work is or should be done. I claim that every- 
body has the privilege to construct and make their own microscope, measuring, and 
illuminating apparatus, ruling machine, and machinery to make those and all other de- 
vices that anybody wishes to make for private or general public use, as I have done. 
As it is proper for a man to uphold and prove what he has said, or either -retract 
such quotation, I would ask Prof. Seaman to send the following rulings made by 
Prof. Rogers. All test plates should be ruled in bands, beginning with and running 
up every 10,000 to the denominations as given below :— 
1 plate ruled up to 200,000, or 250,000 lines per inch.

3 stage mic. ruled 1, 10, 100, 1,000 lines per mm. 
3, stage mic. ruled 100, 1,000, 5,000, 10,000 lines per inch. 
When I will appoint a committee of four to measure and resolve them. And the 
Professor can appoint his committee and do likewise with my rulings. 
We have numerous times resolved 200,000 and over. I have the facilities to do it 
with, and measuring likewise.

To THE Eprror :—You will take some interest in the fact that a Microscopical 
Society has at last been started in Calcutta. During the last 150 years we have made 
great progress here, and from having been a malarious rice-swamp at the commence- 
ment of that period, we have become a healthy and prosperous centre of trade and 
and commerce. We have had an University for over 30 years and have several 
societies, one of which, the Asiatic Society, is world-wide in its fame; but until the 
day before yesterday we had no Microscopical Society! It has not been for want of 
work, for our.flora and fauna, and especially the microscopical portion of it, is unex- 
plored. I only hope that interest in the new association will be maintained, and that 
its members will always work loyally in its interests and not put forth all their strength 
at the first go-off. I send by this mail a copy of a local paper containing a short notice 
of our first meeting, and as soon as they are ready will post you a copy of our Rules, 
etc. Dr. Simpson, our president, is health officer here, and a trained microscopist. 
I believe he has been in both Koch and Pasteur’s laboratories. Our vice-president, 
Mr. I. Wood-Mason, is a celebrated zoologist out here, and specially strong in en- 
tomology and microscopy. We haveanF.L. S., and one or two other doctors amongst 
us, and several members take a lively interest in local bacteriology and botany; so 
that on the whole I hope the society, which I may venture to call mine, will do good 
work. Iam, dear sir, 
Yours truly, W. I. SIMMONS.
