160 REPORT—1850. 
Tenth Report of a Committee, consisting of H. EK. Srrickuanp, Esq, 
Prof. Dauseny, Prof. Hensiow, and Prof. LinpuEy, appointed 
to continue their Experiments on the Growth and Vitality of 
Seeds. 
Tue seeds which were collected in 1842 have been sown for the third time 
this season, and the results are registered in the accompanying Table, and 
also in the General Summary of the results of these experiments since 1841, 
which is annexed. 
Besides those named in the General Summary, there have been small 
quantities of many kinds submitted to a single sowing ; but as in most cases 
the probable age at which they ceased to germinate could not be traced, . 
they have been omitted. This observation applies more especially to those 
registered in vol. xiii. pp. 96-99, vol. xv. pp. 22-24, and vol. xvi. p. 14, of 
these Reports, where, by glancing at the numbers of each kind sown, it will 
be seen, that a just result could not be arrived at from so slight a test. Those 
kinds however which germinated at any known period have been inserted, 
merely to show that vitality had not altogether ceased at such ages. 
We are again indebted to Miss Molesworth of Cobham, Surrey, for many 
packets of seeds from which we selected six kinds, being all that were avail- 
able for our purpose; the remaining kinds having been either already tested, 
or, if new seeds, were in such small quantities, as would not admit of their 
being distributed in conformity with the specified instructions. 
The seeds sent to Cambridge last year were not sown till the present sea- 
son, the results of which liave been received and registered in the General 
Summary.
