✦ Synopsis

We examine the scaling law BJM? which connects organismal resting metabolic rate B with organismal mass M, where is commonly held to be 3/4. Since simple dimensional analysis suggests "2/3, we consider this to be a null hypothesis testable by empirical studies. We re-analyse data sets for mammals and birds compiled by Heusner, Bennett and Harvey, Bartels, Hemmingsen, Brody, and Kleiber, and "nd little evidence for rejecting "2/3 in favor of "3/4. For mammals, we "nd a possible breakdown in scaling for larger masses re#ected in a systematic increase in . We also review theoretical justi"cations of "3/4 based on dimensional analysis, nutrient-supply networks, and four-dimensional biology. We "nd that present theories for "3/4 require assumptions that render them unconvincing for rejecting the null hypothesis that "2/3.

## Abstract In a recent examination of the integrated nature of inflation, Culver and Papell (__Journal of Applied Econometrics__, 1997) applied a range of unit root and stationarity tests to data from a panel of 13 OECD economies. The results obtained were mixed. While little evidence of stationar

The 13C NMR spectra of the synthetic chlorins H,(OEC), Ni(TMC) and H,(TPC) have been re-examined. Evidence from single-frequency proton decoupled, proton coupled, and 2D 13C-13C INADEQUATE experiments show that the previous assignments of the meso-substituted chlorins were incorrect.

## Abstract The vagus (X) and cranial root of the accessory nerve (crXI) are traditionally described as arising from a series of rootlets from the medulla oblongata. Descriptions of the number of rootlets vary, and the existence of the crXI is contested. Here we report the results of dissections in
