    Note: In the mouth of bloodsucking leeches are three convergent, serrated jaws, moved by strong muscles. By the motion of these jaws a stellate incision is made in the skin, through which the leech sucks blood till it is gorged, and then drops off. The stomach has large pouches on each side to hold the blood. The common large bloodsucking leech of America ( Macrobdella decora) is dark olive above, and red below, with black spots. Many kinds of leeches are parasitic on fishes; others feed upon worms and mollusks, and have no jaws for drawing blood. See Bdelloidea. Hirudinea, and Clepsine.

Leach (steam automobile company)

Leach or Leach Steamer was an American automobile company started in 1899.

Leach (automobile)

Leach-Biltwell Motor Company designed, engineered, manufactured, and distributed luxury automobiles in the early 1920s. They used a Continental 303.1 cubic inch inline six-cylinder engine. Some of the advanced features of the Power-Plus Six included a tilt and telescoping steering column, removable steering wheel (to be used as an anti-theft feature) and a directional signal/stop light box on the rear fender (with the control switch on the dashboard).

Perhaps the most distinctive feature of the Power-Plus Six was the pillarless "California top" that was a popular accessory for open touring cars in the 1920s. This top effectively made the car a " hardtop," thirty years before the hardtop-convertible became a popular body style in the United States. Body styles included both two and four door models.

Leach cars were high-priced for the day, and the company found itself in financial hot water by 1923. It closed its shutters in early 1924 after a grand total of about 250 cars (chassis with and without factory bodies) were produced.
