TRANSACTIONS OF SECTION G. 905 
(6) An arrangement was shown in operation for obtaining the diagrams of 
crank effort, by means of a special apparatus which is done on smoked 
glass. These can either be printed off, or used direct in the lantern for 
illustration upon the screen. 
The dynamometer coupling was then described and illustrated, after which a 
diagram giving a complete table of the results of several trials of the experimental 
engine was shown, and copies were distributed amongst members of the Section." 
The various conditions of the trials were as follows :— 
Triple unjacketed condensing. 
Triple jacketed condensing. 
Jompound unjacketed condensing. (I. and II.) 
Compound jacketed condensing. (I. and II.) 
Compound unjacketed condensing. (II. and III.) 
Compound unjacketed non-condensing. (II. and III.) 
Single unjacketed condensing. (II.) 
Single jacketed condensing. (II.). 
These tables showed at a glance the method adopted for tabulating the results 
of the trials which had been carried out by the senior lecturer, Mr. Dunkerley. 
The hydraulic tank and sump was next alluded to, and the new form of valves 
for rapidly operating with the jet under pressure was mentioned ; a brief descrip- 
tion of the other laboratory apparatus illustrated on the diagrams then concluded 
the paper.
