culiar manner on amygdalin to pro- 

 duce volatile oil of bitter almonds. 



EMULSION. A milky liquid in 

 which an oil is suspended, as in milk. 



EMUNCTOKIES. The vessels of 

 the skin which exhale perspiration 

 are so called. 



ENAMEL. The hard ivory por- 

 tion of teeth. Glass and oxide of tin 

 fused together. 



ENCRINITES. FossU crinoideans 

 resembling a lily. 



ENCYSTED (from ev, in, and kvc- 

 Ticabag). Fluid or other tumours en- 

 closed in a sack of membrane. It is 

 necessary, in removing them, to cut 

 out or destroy the sack also. 



ENDEMIC (from ev, and drj/inc, a 

 people). A disease or peculiarity be- 

 longing to a particular people or race. 



ENDIVE. Chichorium endiva. 

 The varieties are the green and 

 white curled, yellow, and broad 

 leaved. The green curled is earliest : 

 sow in April and May, and for gen- 

 eral crops, in June or July, at inter- 

 vals, to suit the table or market. 

 When the seedlings are three inches 

 high, transplant to a good soil, and 

 set a foot apart each way ; tie up to 

 blanch when full-sized. They must 

 be attended to and treated like lettuce. 

 One ounce of seed furnishes four to 

 five thousand plants. It is a bitter 

 salad, used raw, and also in stews : 

 with care it may be preserved like 

 cabbages through the winter. 



ENDOCARP (from ev6ov, within, 

 and Kapxof, a fruit). The middle 

 part of a fruit ; it forms the flesh of 

 the apple, peach, cherry, &.c. 



END O GENS (from evdov, and 

 yei.vofj.ai, I grow). Plants or trees 

 which do not enlarge their trunks by 

 any addition of wood exterior to that 

 existing the year before. One of the 

 great divisions of the vegetable king- 

 dom, including palms, grasses, and 

 numerous bulbous plants. The leaves 

 are furnished with straight veins, the 

 flowers usually divided into three 

 parts or some multiple of that number. 



ENDOPLEURA (from evdov, and

E N D O R H I Z .E (from cvdov, and 



I ^iCa, a root). A term invented by 

 1 R ichard for the embryo of monocoty 

 ledons, in which the radicle has to 

 rupture the integument at the base 

 of a seed prior to entering into the 

 earth, appearing as if it came from 

 within the mother root. 



ENDOSMOSE (from ev6ov, and 

 uff^of, impulsion). A term invented 

 by Dutrochet to designate the pas- 

 sage of fluids through membranes. 

 Penetration is an analogous term. 

 Whenever two fluids are separated 

 by a membrane or tissue without 

 sensible pores, both of which moisten 

 it, there is a passage of each fluid, 

 one into the other : but this is often 

 with different rapidities, the fluid af- 

 fecting the tissue most passing with 

 the greatest rapidity. The move- 

 ment continues until the mixture on 

 each side is similar. This also oc- 

 curs with gases. It is controlled by 

 electricitv, as Dr. Draper has shown.

 tines. See Horse, Ox, &o. 



ENTOMOLOGY (from evTopa, in- 

 sects, and /loyof, a discourse). The sci- 

 ence treating of insects. See Insects. 



ENTOZOA (from evTog, and l^uov, 

 an animal). A tribe of worms, many 

 of which are parasitic to the intes- 

 tines and other parts of animals. 



EOCENE (from j?uf, the daicn, and
