INFLAMMATION. An unnatu- 

 ral increase of circulation, lilood, and 

 heat in any part. It originates in 

 irritation, colds, contagion, and un- 

 healthy conditions of the nervous 

 system, and may attack any part. It 

 begins with dryness, heat, pain, and 

 tension, which is succeeded hy in- 

 creased vascularity, swelling, and se- 

 cretion, and terminates naturally by 

 resolution to the primary states, by 

 the adhesion of parts or the forma- 

 tion of pus, ulceration, mortification, 

 and death of the part. 



If the animal be vigorous, it is to 

 be treated by bleeding, purging, blis- 

 ters, and cooling applications. But 

 the inflammations ot weakly animals, 

 especially when arising from conta- 

 gion and ending in ulcerations and 

 gangrene, is to be treated by stimu- 

 lants and tonics, of which carbonate 

 of ammonia {sal volatile) and bark are 

 the best. 



INFLATED. Distended like a 

 full bladder, as the carpels of some 

 plants. 



INFLEXED. Bent inward. 



INFLECTION. In optics, the 

 same as difTraction. 



INFLORESCENCE. The group- 

 ing of flowers on the stems of plants ; 

 the principal forms are the spike, ra- 

 ceme, corymb, umbel, panicle, thyr- 

 sus, catkin, capitulum. 



INFLUENZA. An epidemic cold, 

 with sore throat and fever, prevail- 

 ing in some springs. 



INFUNDIBULIFORM. Shaped 

 like a funnel. 



INFUSION. A liquor obtained by 

 macerating herbs, &c., in hot or cold 

 water. 



INFUSORIA. The minute ani- 

 malcules of infusions and stagnant 

 waters ; some possess a mineral ca- 

 sing ; and the remains of innumera- 

 ble myriads are found in rocks, such 

 as tripoli, polirsheifer ; hence termed 

 infusorial, or infusory rocks or forma- 

 tions. 



INGLUVIES. The crop of birds. 



INGUINAL. Connected with the 

 groin {inguen).

INK. To make black ndt ul the 

 best quality, take 12 parts gall-nuts, 

 f) of green vitriol, and 5 of gum ; the 

 galls are to be well pounded and 

 boiled, and the other ingredients af- 

 terward added ; 1 gallon of water is 

 used for every pound of galls. Oak 

 bark, logwood, and otlier substances 

 are often used in place of the galls : 

 the quantity must be two or three 

 times greater. 



The indelible ink, for marking lin- 

 en, is a solution of nitrate of silver 

 (lunar caustic). It is used with a 

 clean pen on a place previously soaked 

 with a little salt ; the marking is to 

 be exposed to light to blacken. It is 

 removable by chlorine and ammonia. 



Blue ink is a patent solution of 

 Prussian blue in oxalic acid and wa- 

 ter ; gum is added to make it adhere 

 to paper ; it is perishable, and easily 

 dissolved. 



INJECTION. In farriery, a fluid 

 medicine thrown into any cavity of 

 the body by a squirt or syrini^e. 



INNER BARK. The liber of bot^ 

 anists, bass. 



INNOMINATUM BONE. The 

 bone of the buttock ; aitch, or adze 

 bone. 



INOCULATION. The introduc- 

 tion under the skin of animals of a par- 

 ticular poison, fluid, or virus, to pro- 

 duce a specific disease, as smallpox. 

 Budding and the transfer of grass 

 turfs are also called inoculation by 

 farmers. 



INORGANIC. Not organic or de- 

 structible by heat, as the ashes of 

 plants, minerals, &c. 



INOSCULATION. The union of 

 the extremities of veins and arteries. 



INSECTIVOROUS. Birds, ani- 

 mals, or reptiles that prey on insects. 



INSECTS. The following brief 

 sketch of Entomology is chiefly by 

 Mr. Swainson, from Loudon's Ency- 

 clopaedia : 



"Insects, above all other animals, 

 are by far the most injurious to the 

 agriculturist, not only from their num- 

 bers, but from their attacking the 

 produce of the earth in all its stages 

 of growth and maturity.
