[83] The term micropyle (a little gate) has heretofore only been used in its relation with the vegetable kingdom: it is used to denote the opening or foramen towards which the radicle is always pointed.
[84] Dr. Halifax adopts the method of killing the insect with chloroform; he then immerses it in a bath of hot wax, in which it is allowed to remain until the wax becomes cold and hard; with a sharp knife sections are easily made in the required direction without in the least disturbing any of the more fragile parts, or internal organs of the specimen.
