Des Cartes, that the sine of the angle ZKA should be to the sine of the angle HKB as 3 to 2, supposing that this is the proportion of the refraction of glass; or rather, that the sine of the angle KGL should have this same ratio to the sine of the angle GKQ, considering KG, GL, KQ as straight lines because of their smallness.
The radiator fitted to this engine, together with the water-jackets, has a capacity of 25 litres of water, it is rectangular in shape, and is normally tilted at an angle of 30 degrees from vertical. Its weight is 26 kg., and it offers but slight head resistance in flight.
The straw should be dried in the sun for several days, stored if necessary in an air-tight container and used within two months. The ratio of paddy straw to mushroom spawn should be 1 kg "prepared" straw to 4% spawn. Procedure: First the straw must be prepared. The straw should be cut to 3-5 cm pieces.
I am a good deal discomforted by this visit of ye Kg. of Pr. It seems so natural for persons to wish that Episcopacy shd be bestowed upon those who desire to receive; and people for ye most part have very little or no notion as to ye unsoundness even of the sounder part of ye G. Divines.
An average adult croc is about 250 kg and about two to three metres long. It takes 15-20 people to carry it. Once it is released in the pool the ropes and rubber bands are removed and the last unfortunate or brave man, depending on how you look at it, makes a run for his life over the edge of the pond onto the safety of dry land.
The weights in comparison with the power of the engine realised a considerable advance over anything made to date, since the two engines weighed together realised 42 kg., the firebox and boiler 60 kg., the condenser 15 kg., or a total of 117 kg. for approximately 40 horse-power or a little less than 3 kg. per horse-power.
One other industry should also be mentioned. With the development of printing, which will be discussed below, the paper industry was greatly stimulated. The state also needed special types of paper for the paper currency. As already mentioned, silver in form of bars had been increasingly used as currency in Sung time. The yearly government production of silver was c. 10,000 kg.
