Of the following statements those in quotation marks are from the observations of Lascelles:1

"West India coffee is for the most part even-sized, pale, and yellowish, firm and heavy, with fine aroma, losing little in weight by the roasting process."

"Brazil coffee is larger, less solid, greenish or white, usually styled by the brokers 'low' or 'low middling.'"

"Java coffee is smaller, slightly elongated, pale in color, deficient in aroma and essential oil, and light."

"Ceylon produces coffee of all descriptions, but the ordinary plantation coffees are even-colored, slightly canoe-shaped, strong in aroma and flavor, of considerable gravity, and admit better of adulteration than most other kinds."

Mocha is usually considered the best coffee of commerce. It is stated that East India coffees are sometimes shipped to Arabia and exported from this latter country as genuine Mocha coffee. The seeds of the Mocha are small and dark yellow.

Java coffee when new is a pale yellow and is then cheaper than when old and brown. This color is partly a result of the method of curing in addition to the effects of age.

The high price of Java has led to the coloring of cheaper grades with mineral pigments or otherwise, in imitation of this favorite coffee. It may be well to state that this practice can not be general, since no foreign coloring matters were found in the Javas examined in the course of the investigations treated of in this work, though it is probable that coffees colored by exposure to a high, moist heat may have escaped detection.

The following table, by Thorpe,1 indicates the variations in the size of coffee beans:

Number of seeds in a measure holding 50 grams of water.

Rio Coffees form a very large proportion of those consumed in the United States. Judging from the above table, the Rio coffee bean is considerably smaller than the Java and is approximately the size of the Mocha.
