This book (hardcover) is part of the TREDITION CLASSICS. It contains classical literature works from over two thousand years. Most of these titles have been out of print and off the bookstore shelves for decades. The book series is intended to preserve the cultural legacy and to promote the timeless works of classical literature. Readers of a TREDITION CLASSICS book support the mission to save many of the amazing works of world literature from oblivion. With this series, tredition intends to make thousands of international literature classics available in printed format again - worldwide.

An Introduction to Chemical Science Chapter 1 THE METRIC SYSTEM.

1. The Metric System is the one here employed. A sufficient knowledge of it for use in the study of this book may be gained by means of the following experiments, which should be performed at the outset by each pupil.

2. Length.

Experiment 1.-Note the length of 10 cm. (centimeters) on a metric ruler, as shown in Figure 1. Estimate by the eye alone this distance on the cover of a book, and then verify the result. Do the same on a t.t. (test-tube). Try this several times on different objects till you can carry in mind a tolerably accurate idea of 10 cm. About how many inches is it?

In the same way estimate the length of 1 cm, verifying each result. How does this compare with the distance between two blue lines of foolscap? Measure the diameter of the old nickel five- cent piece.

Next, try in the same way 5 cm. Carry each result in mind, taking such notes as may be necessary.

(Fig. 1)

3. Capacity.

Experiment 2.-Into a graduate, shown in Figure 2, holding 25 or 50 cc. (cubic centimeters) put 10 cc. of water; then pour this into a t.t. Note, without marking, what proportion of the latter is filled; pour out the water, and again put into the t.t. the same quantity as nearly as can be estimated by the eye. Verify the result by pouring the water back into the graduate. Repeat several times until your estimate is quite accurate with a t.t. of given size. If you wish, try it with other sizes. Now estimate 1 cc. of a liquid in a similar way. Do the same with 5 cc.

A cubic basin 10 cm on a side holds a liter. A liter contains 1,000 cc. If filled with water, it weighs, under standard conditions, 1,000 grams. Verify by measurement.

4. Weight.

Experiment 3.-Put a small piece of paper on each pan of a pair of scales. On one place a 10 g. (gram) weight. Balance this by placing fine salt on the other pan. Note the quantity as nearly as possible with the eye, then remove. Now put on the paper what you think is 10 g. of salt. Verify by weighing. Repeat, as before, several times. Weigh 1 g., and estimate as before. Can 1 g. of salt be piled on a one-cent coin? Experiment with 5 g.

5. Resume-Lengths are measured in centimeters, liquids in cubic centimeters, solids in grams. In cases where it is not convenient to measure a liquid or weigh a solid, the estimates above will be near enough for most experiments herein given. Different solids of the same bulk of course differ in weight, but for one gram what can be piled on a one-cent piece may be called a sufficiently close estimate. The distance between two lines of foolscap is very nearly a centimeter. A cubic centimeter is seen in Figure 1. Temperatures are recorded in the centigrade scale.

My bank account showed exactly $42.18, and my student loan notifications were flashing red. I lived in a sweltering Queens apartment with my Aunt Lydia, where the air was thick with the smell of stale frying oil and the constant threat of being homeless. Lydia handed me a grainy photo of a man twice my age and told me she had already "sold" me to him. He was a dry cleaner looking for a wife, and in exchange for my hand, he would pay off her credit cards and my debt. If I didn't show up for the date that night, my boxes would be on the curb by midnight. I arrived at the cafe in a state of panic, my selective mutism making it impossible to even breathe. In the crowded room, I accidentally sat at the wrong table. Instead of the man from the photo, I found myself facing Gerhard Holcomb—the cold, terrifyingly handsome billionaire whose family owned the very museum where I worked. He didn't send me away; instead, he studied my trembling hands and offered me a different deal: a two-year contract marriage, a two-million-dollar payout, and a strict clause forbidding any children. I signed the papers and moved into his Park Avenue penthouse, thinking I was finally safe. But when I went back to the old apartment to retrieve the only memento of my dead parents, Lydia lashed out, leaving me bleeding from a head wound. Gerhard’s retaliation was absolute—he had her arrested and her building foreclosed on within hours, claiming he was simply "protecting his assets." As I recovered in his silent, glass-walled home, I saw a call from a famous socialite flash on his phone, and a cold truth settled in my gut. I wasn't just a wife; I was a placeholder, a silent shield used to fend off the women from his past. I looked at the massive pink diamond on my finger and realized the silence I had lived in my whole life was about to become my most expensive prison. I had traded a life of poverty for a high-stakes game of shadows, and now I had to survive the man who claimed to own me.

The heavy thud of the release stamp was the only goodbye I got from the warden after five years in federal prison. I stepped out into the blinding sun, expecting the same flash of paparazzi bulbs that had seen me dragged away in handcuffs, but there was only a single black limousine idling on the shoulder of the road. Inside sat my mother and sister, clutching champagne and looking at my frayed coat with pure disgust. They didn't offer a welcome home; instead, they tossed a thick legal document onto the table and told me I was dead to the city. "Gavin and I are getting engaged," my sister Mia sneered, flicking a credit card at me like I was a stray dog. "He doesn't need a convict ex-fiancée hanging around." Even after I saved their lives from an armed kidnapping attempt by ramming the attackers off the road, they rewarded me by leaving me stranded in the dirt. When I finally ran into Gavin, the man who had framed me, he pinned me against a wall and threatened to send me back to a cell if I ever dared to show my face at their wedding. They had stolen my biotech research, ruined my name, and let me rot for half a decade while they lived off my brilliance. They thought they had broken me, leaving me with nothing but an expired chapstick and a few old photos in a plastic bag. What they didn't know was that I had spent those five years becoming "Dr. X," a shadow consultant with five hundred million dollars in crypto and a secret that would bring the city to its knees. I wasn't just a victim anymore; I was a weapon, and I was pregnant with the heir they thought they had erased. I walked into the Melton estate and made an offer to the most powerful man in New York. "I'll save your grandfather's life," I told Horatio Melton, staring him down. "But the price is your last name. I'm taking back what's mine, and I'm starting with the man who thinks he's marrying my sister."

Trigger/Content Warning: This story contains mature themes and explicit content intended for adult audiences(18+). Reader discretion is advised. It includes elements such as BDSM dynamics, explicit sexual content, toxic family relationships, occasional violence and strong language. This is not a fluffy romance. It is intense, raw and messy, and explores the darker side of desire. ***** "Take off your dress, Meadow." "Why?" "Because your ex is watching," he said, leaning back into his seat. "And I want him to see what he lost." ••••*••••*••••* Meadow Russell was supposed to get married to the love of her life in Vegas. Instead, she walked in on her twin sister riding her fiance. One drink at the bar turned to ten. One drunken mistake turned into reality. And one stranger's offer turned into a contract that she signed with shaking hands and a diamond ring. Alaric Ashford is the devil in a tailored Tom Ford suit. Billionaire CEO, brutal, possessive. A man born into an empire of blood and steel. He also suffers from a neurological condition-he can't feel. Not objects, not pain, not even human touch. Until Meadow touches him, and he feels everything. And now he owns her. On paper and in his bed. She wants him to ruin her. Take what no one else could have. He wants control, obedience... revenge. But what starts as a transaction slowly turns into something Meadow never saw coming. Obsession, secrets that were never meant to surface, and a pain from the past that threatens to break everything. Alaric doesn't share what's his. Not his company. Not his wife. And definitely not his vengeance.
