1. 1. Pooled blood samples obtained from a number of Eisenia foetida specimens were analysed for the compounds indicated below. 2. 2. The levels of free long chain fatty acids, glycerides, phospholipids and sterols were found to be quite high. 3. 3. Haemoglobin was found to be the only protein detectable and its amino acid composition was compared with previous results obtained for other invertebrates and mammalian blood pigments. 4. 4. The free amino acids were all at a low level except for exceptionally large amounts of arginine and ornithine. 5. 5. Low levels or absence of sugars, organic acids and pyrimidine and purine compounds were recorded. 6. 6. The results are compared with values obtained for other invertebrate species.

Research is being carried out in New Brunswick to develop a better understanding of the nature and function of land-survey systems in a dynamic society. This paper briefly outlines some of the concepts that have been developed, describes the modeling techniques that have been applied to the study, and presents some of the requirements that have been formulated for a land-survey system.

1. 1. Lipid extracts obtained from Eisenia foetida were purified and fractionated into the major polar and less polar lipid classes. 2. 2. As expected an extremely limited range of sphingolipids and sulphatides was found. 3. 3. The only glycerophospholipids found to occur at high levels were phosphatidyl choline, phosphatidyl ethanolamine and phosphatidyl serine respectively. No α-glyceryl ether groupings were detected, but plasmalogen levels were quite high for phosphatidyl choline and phosphatidyl serine. 4. 4. The neutral lipid was characterized by its comparatively high monoglyceride and free fatty acid content, though most of the fatty acid was present as triglyceride. No O-alkyl diglycerides were detected in the triglyceride fraction but O-alk-enyl-diglycerides (neutral plasmalogen) were present. 5. 5. The major sterols present were cholesterol and 7-dehydrocholesterol with unidentified more polar material also present. 6. 6. The findings are compared with those obtained from studies on other invertebrates.

The surveying profession has the opportunity to make an important contribution towards the design and development of information systems of the urban physical environment. However, the achievement of this role will require an awareness of the urban information process and, more especially, an understanding of the needs for urban information. This can only be attained through a rigorous urban surveying research program.

A previous publication, ENH854 (http://edis.ifas.ufl.edu/EP107), listed over 350 native and non-native plant species for south Florida. This new publication was developed as a supplement to ENH854, but it is also a good stand-alone reference for people wishing to add native plants to their private yards or public landscapes, or simply to learn more about them. This document is ENH 875, one of a series of the Environmental Horticulture Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

A community garden is a collaborative greenspace in which the participants share in both the maintenance and the rewards. There is a long tradition of community gardening in various parts of the United States and around the world. This publication has been developed to assist those who wish to form a community garden in Florida. This document is ENH 966, one of a series of the Environmental Horticulture Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
