01 level of significance one summer but not in the other. 01 level significance in 20 of the pairs. The experimental differences found for spiral number, thread length, angle regularity, radial number and spiral zone are particularly consistent. Drug Application Some spiders were given drugs more than once, though never more than 3 times. At least 2 weeks intervened between drug-administrations to the same animal. Under laboratory conditions, all spiders building a web on a given morning do so within a few minutes of each other.

We make the webs visible by spraying them with white paint, photograph the sprayed webs, and measure and evaluate the patterns in terms of plane geometry. Recently better lighting conditions and more sensitive photographic film has permitted good photography of unsprayed webs. Most experimental effects are sufficiently described as departures from the geometric pattern of the normal web, but because so many factors influence daily web-building, many webs have to be evaluated in order to obtain statistically valid data.

It can then be placed in the test tube in preparation for nitrogen determination (see page 17). B. Changes of Webs with Age There can be no doubt that a small baby spider builds a web different from that of a full-sized animal. Several questions can be asked as to the changes: Is there a continuous change in web size and pattern from babyhood to adulthood and old Changes of Webs with Age 47 age, or are there discontinuous changes, certain periods in which distinct parameters are altered? We can also ask whether the pattern changes are related to the growth of the body of the spider.
