"This book is one that I can heartily recommend." -- Sir Harold Spencer Jones, F. R. S., formerly Astronomer Royal
A model of comprehensive scholarship, The History of the Telescope relates not only the stories of early inventors and astronomers but also the rarely recorded details of the instruments themselves and their makers. This remarkable chronicle covers many fields, including professional and amateur astronomy, optics, glass and lens technology, and the craft of the precision instrument.
Author Henry C. King bases his accounts primarily on first-hand sources -- the letters, memoirs, papers, and treatises of the men who worked with telescopes. The great intellects (Roger Bacon, Galileo, Newton) and innovators (Tycho Brahe, Huygens, Hooke, Sir William Herschel) receive their due, along with lesser-known craftsmen and amateurs: the seventeenth-century Italian telescope makers Campani and Divini; the great London instrument artists Graham, Dolland, and Ramsden; and the experimenters Foucault and Brashear, whose contributions to mirror manufacture remain fundamental to all levels of astronomical endeavor. The modern-day successors of these men and their achievements bring this history to its conclusion in the mid-twentieth century, with profiles of the instruments still in use today.
A prime resource on the evolution of the telescope, this volume is magnificently illustrated with nearly 200 portraits, diagrams, and photographs.

Not durable for a large breed
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG, Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
I received this toy about 2hrs ago. My dog tore a hole in it already. Not made for Rottweiler/American Bulldog breed, apparently. 🙂 Love that there isn't stuffing though, at least she's not making a mess, lol!

My dog loves it.
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
I thought I was going to have to return this dog toy because my dog was afraid of the toy, especially the squeaker. But after a while, he finally did start playing with it and now he won’t let the other dogs touch his frog. It’s so bad that if they do touch it, he rips it out or their mouth, jumps up into a chair, and lays on top of it so they can’t get it. He still doesn’t like the squeaker if it’s down in front of him, but if I’m in another room, the squeaker makes him come running. He loves the squirrel I got him too. But the material of the frog seems really durable. The part I like the most of that it’s like a puppet and you can stick your hand in it or an empty bottle of water and then Velcro it shut. If your dog doesn’t like the squeaker, there is a pouch in the mouth of the frog that you can access through this velcroed area and cut it out. Definitely a must have if you have a tough chewer.

Don't waste your money!

Do NOT buy unless you like throwing away your money! This Ethical Pets 54093 Skinneeez Frog seemed like a great dog toy, but my Malti Poo destroyed it within TEN minutes! He actually ate the material and half of the squeaker before I found the other half. Guess we’ll be seeing that outside in a few days! This toy is listed as “Durable Dog Toy”, but it is NOT. I’ve got dog toys from the dollar store that lasted for months! We will not be buying nor recommending this product again. Don’t waste your money!

Great toy
Color: Grey
My girl loves this toy. She has a lot of toys but this is her favorite. She is a 26 lb mini golden and we have had it over a year. It is just now starting to show wear. Once it is completely worn out I will buy it again!
