electrical connection. This section of the jaws also contains a screw hole at the side so 
that the jaws may be placed at right angles, with the opening parallel with the rod. A 
screw hole on top of the other section serves to place the jaws at right angles to the rod 
with the opening horizontal.................................................... § 3.75 
Muscle Lever, Light; with double hooks, pulley, and after-loading screw. Mounted on a 
rubber block with insulated binding posts. (J.E.P.:5S; Z.L.E.P.:40)................... 3.90 
Muscle Lever, Heavy. Consisting of a tripod with a clamp at the top for holding a muscle 
lever and a cross-piece underneath supporting an adjustable lever arranged for electrical 
stimulation and taking a scale pan................................................ 3.80 
Clamp, Gaskell’s.. A clamp with comparatively sharp, hard-rubber jaws operating on two 
small guide rods by means of a fine screw and nut attached to the movable section of the 
jaw. Used for compressing heart muscle and the sartorius........................... 2.50 
Crank-Myograph. Attachable to a support by means of a right angle clamp. The base 
plate supports a hot water chamber and a notched and perforated bell-crank lever with 
an after-loading screw. The hot water chamber is supplied with tublatures at the bottom 
for securing circulation of the water supply, and the top is provided with a cork covering 
having a central brass plate extending slightly above the cork. (B.E.E.P.:31; K.H.P.:119) 25.00 
Myograph, Double. Consisting of two No. 59207 heart or muscle levers, with perforated 
stylus-holder and spiral spring tension regulated by means of a collar and set-screw, and 
a No. 59007 muscle clamp. (H.E.P.:5S; S.P.P.:268)................................. 13.25 
Myograph, Frog Board, Hall’s. Attachable to a support by means of a right angle clamp. 
The base board is covered with a heavy cork plate, and a bell-crank with an after-loading 
screw is attached to one end of the base. The bell-crank stylus-holder is perforated for 
the use of weights. Two of these myographs and a muscle clamp make an excellent 
double myograph of the frog board type. (H.E.P.:50-51, 54, 64-66, 75, 85; H.L.P.:54). . 11.25

Myograph, Spring, DuBois-Reymond’s; modified by Lingle. This type was originally con¬ 
structed to meet the requirements of the Physiology Department of the University of 
Chicago. It consists of a heavy rectangular support with three legs, provided with quick¬ 
acting leveling screws. The sliding paper-carrier, to which is attached the smoked paper, 
travels over two nicely adjusted guide rods. Above the two guide rods used for thé 
carrier is a third which carries the compression spring used to actuate the carrier. A 
projection from the top of the paper-carrier is used to compress the spring. At the side 
of the paper-carrier is a projecting rod with a notch which engages the trigger attached 
to the side of one of the uprights of the rectangular frame. When the trigger releases the 
paper-carrier, it shoots to the other side of the supporting frame and is caught, without 
back-lash, by a spring catch attached to the top of the other upright. Adjustable along 
the carefully planed surface of the horizontal part of the support are two adjustable 
trip keys with binding posts. The keys are tripped by projections extending downward 
from both sides of the paper-carrier. (C.U.; H.T.P.:65; K.H.P.:120' LS '593 595 703'

Lever, Heart or Muscle. A carefully constructed lever with perforations in the bell-crank 
stylus-holder for weights, and a spiral spring with collar and adjusting screw for adjust¬ 
ing the tension. See illustration on page 218. (,H.E.P.:58-60)...................... 
Lever, Frog Heart, Hall’s. A lever with a pin for a cork on one end, and a counterpoise 
on the other. Pivoted on a sharp-pointed tripod. The pin end of the lever is arranged 
for the insertion of a stylus. (H.E.P.:75)............................
