Cold-hammering was used in the late Stone Age to produce plates of gold for ornamental purposes, and this metal has always been synonymous with beauty, wealth and power. Considerable quantities were accumulated by ancient peoples. The coffin of Tutankhamun (a minor Pharaoh who was only 18 when he died) contained no less than 112 kg of gold, and the legendary Aztec and Inca hoards in Mexico and Peru were a major reason for the Spanish conquests of Central and South America in the early sixteenth century. Today, the greatest hoard of gold is the 30000 tonnes of bullion (i.e. bars) lying in the vaults of the US Federal Reserve Bank... 

According to the Journal of Ihc Hoard of AgricultMeJ [rom 500 to 1000 acres are under peppermint cultivation in England, In this country black mint yields twice as niiicb oil as does white mint, and as a result the cultivation ol the latter has been supplanted to a considerable extent.

Uses of Formaldehyde. Formaldehyde is the simplest and most reactive aldehyde. Condensation polymerization of formaldehyde with phenol, urea, or melamine produces phenol-formaldehyde, urea formaldehyde, and melamine formaldehyde resins, respectively. These are important glues used in producing particle hoard and plywood. 

A new polymer type which emerged as important materials for circuit hoards are polycyanurates. The simplest monomer is the dicyanate ester of hisphenol A. When polymerized, it forms three-dimensional, densly cross-linked structures through three-way cyanuric acid (2,4,6-triazinetriol) ... 

The largest application of polycyanurates is in circuit hoards. Their transparency to microwave and radar energy makes them useful for manufacturing the housing of radar antennas of military and reconnaissance planes. Their impact resistance makes them ideal for aircraft structures and engine pistons. ... 

In the chemical industry, simple aldehydes and ketones are produced in large quantities for use as solvents and as starting materials to prepare a host of other compounds. For example, more than 1.9 million tons per year of formaldehyde, H2C=0, is produced in the United States for use in building insulation materials and in the adhesive resins that bind particle hoard and plywood. Acetone, (CH.3)2C"0, is widely used as an industrial solvent approximately 1.2 million tons per year is produced in the United States. Formaldehyde is synthesized industrial ) by catalytic oxidation of methanol, and one method of acetone preparation involves oxidation of 2-propanol. 

Structural characteristics of compounds with X Me = 8 are collected in Table 17. Na3NbF8 and Na3TaF8 compounds that form similar crystal structure [77], The structure of Na3TaF8 was determined by Hoard et al. [136], by means of X-ray diffraction of a single crystal. Na3TaF8 is composed of sodium cations and isolated complex ions TaF83, in an Archimedean antiprism configuration, as shown in Fig. 23.

Other Covalent Radii. In Cu20 and Ag20 each metal atom is equidistant from two nearest oxygen atoms, the interatomic distances corresponding to the radius values 1.18 and 1.39 A for Cu1 and Agl with coordination number two. In KAg(GN)2, in which each silver atom is similarly attached to two cyanide groups1), the effective radius of Agl is 1.36 A. It has been pointed out to us by Dr. Hoard that the work of Braekken2) indicates the presence of strings —Ag—G=N—Ag—G... 

We learned later that crystals of the substance were also given by Professor Franklin to Dr. J. L. Hoard, who is continuing their study at Cornell University. The substance was originally identified (E. C. Franklin, Jour. Am. Chem. Soc., 44, 497 (1922)) as NaC2-Na-HjO, the sodium salt of dicyanimide. Our x-ray investigation led us to adopt the trimeric formula, which was also adopted by Professor Franklin (Ref. 4). 

It is interesting to note, as pointed out to me by Mr. J. L. Hoard, that these considerations lead to an explanation of the stability of trivalent cobalt in electron-pair bond complexes as compared to ionic compounds. The formation of complexes does not change the equilibrium between bivalent and trivalent iron very much, as is seen from the electrode potentials, while a great change is produced in the equilibrium between bivalent and trivalent cobalt. 

I wish to thank Dr. J. L. Hoard for assistance in preparing the photographs and Dr. J. Sherman for the intensity calculations of Table III. 

By contrast, medicines used in the home are not orrly less often eontaminated but also contain lower levels of contaminants and fewer pathogenie orgarrisms. Generally, there are fewer opportunities for contamination here since smaller quantities are used by individual patients. Medicines in the home may, however, be hoarded and used for extended periods of time. Additionally, storage conditions may be imsuitable and expiry dates ignored and thus problems other than those of microbial contamination may be seen in the home. 

There are other causes of pain and pulpal irritation. Hydraulic pressure developed during the seating of a restoration can lead to pulpal damage (Hoard et al., 1978). The movement of fluid under osmotic pressure has been dted as a cause of pain (Brannstrom Astrom, 1972).
